Your WUI Code Compliance Checklist for Wildfire Defense

Building a home where your backyard meets open space is a beautiful dream. But in many areas, that dream comes with the real risk of wildfire. It’s not about giving up on the view; it’s about building smarter so you can enjoy it with peace of mind. This is where WUI codes come in. They aren't just bureaucratic red tape; they are a research-backed guide to constructing a home that can stand up to embers and flames. Getting it right from the start protects your family and your investment. This guide breaks down what you need to know, providing a clear WUI code compliance checklist to help you make informed decisions about materials, design, and landscaping.

Key Takeaways

• Build a dual-layer defense for your property: The most effective protection combines hardening your home with ignition-resistant materials (like Class A roofing and non-combustible siding) and managing the surrounding landscape by creating defensible space to reduce fire fuel.
• Aim for insurability, not just code compliance: Meeting the legal minimum of local building codes is only the first step. Insurance carriers often have stricter requirements, and building to satisfy them is critical for securing coverage and protecting your financial investment.
• Treat wildfire resilience as an ongoing practice: A fire-safe home requires consistent upkeep. Regular seasonal maintenance, such as clearing debris from your roof and managing vegetation, is just as important as the materials you choose during construction.

What is the Wildland-Urban Interface (WUI)?

If you’ve ever admired a home nestled against a forest or perched on a hill overlooking a grassy canyon, you’ve seen the Wildland-Urban Interface, or WUI. It’s simply any area where human development meets or mixes with wildland vegetation. Think of it as the transition zone where the suburbs shake hands with nature. These communities are growing fast because, let’s face it, who doesn’t love a beautiful view and a bit of open space?

The Wildland-Urban Interface isn’t just a geographical term; it’s a critical concept for anyone building or living in these beautiful, but vulnerable, areas. As communities expand further into these natural landscapes, homes are placed closer to the very fuel that wildfires depend on—trees, shrubs, and grasses. Understanding that you live in the WUI is the first step toward building a home that can stand up to the threat of wildfire. It’s not about avoiding these places, but about learning how to build smarter within them. This knowledge empowers you to make choices that protect your property, your family, and the firefighters who defend your community.

Why living in the WUI increases wildfire risk

Living in the WUI means accepting that wildfire is a natural part of the surrounding environment. The risk isn't just from a massive wall of flames; it's often from wind-blown embers that can travel a mile or more ahead of a fire, igniting homes far from the main blaze. The combination of dense, dry vegetation, combustible building materials, and sometimes limited access for emergency services creates a perfect storm for fire.

As more homes are built in these zones, the potential for human-caused ignitions also rises. Unfortunately, many homeowners in the WUI may not fully grasp the specific vulnerabilities of their property or the steps needed to create a fire-resistant home. This is where understanding and embracing best practices for WUI construction becomes so important for community-wide safety.

How building codes create a stronger defense

This is where WUI building codes come in. Think of them as a set of instructions for constructing a more fire-resilient home. These specialized codes are designed to give your property a fighting chance by requiring specific materials and building techniques that resist ignition from embers and radiant heat. They cover everything from the type of roofing and siding you can use to the design of your vents and eaves.

Following these codes is non-negotiable—they represent the legal minimum for construction in high-risk areas. However, it’s crucial to remember that your insurance carrier will likely have its own set of requirements that may be even stricter. Meeting code is the baseline, but aiming for a higher standard of resilience not only makes your home safer but also improves its insurability and value.

What Do WUI Codes Actually Require?

When you hear "building codes," it’s easy to imagine a long list of complicated rules. But WUI codes are really just a practical guide for building a home that can better withstand a wildfire. They focus on reducing a home's vulnerabilities by addressing how it’s built and the area immediately surrounding it. Think of it as a two-part defense system: hardening the structure itself and managing the landscape to keep flames at a distance.

These requirements aren't meant to be restrictive; they’re designed to give your home a fighting chance against embers and flames. The core principles are straightforward and cover three main areas. First, codes specify the use of building materials that resist ignition. Second, they require you to create and maintain a buffer of "defensible space" around your property. Finally, they outline specific structural design standards that close off common entry points for embers. Understanding these key requirements is the first step toward building a safer, more resilient home.

Select fire-resistant building materials

WUI codes are designed to reduce fire hazards by specifying the use of fire-resistant materials for construction. This is one of the most effective ways to protect your home, especially from flying embers, which can travel a mile or more ahead of a wildfire and are a leading cause of home ignition. The goal is to wrap your home in a non-combustible or ignition-resistant shell. This means choosing materials like Class A fire-rated roofing (such as asphalt shingles, metal, or tile), fiber-cement or stucco siding instead of wood, and multi-pane tempered glass for windows. Every material choice contributes to your home's overall defense.

Create and maintain defensible space

Defensible space is a critical component of WUI codes, emphasizing the importance of creating and maintaining a buffer zone around your home. This is your property’s first line of defense. It’s a carefully managed area where flammable vegetation is cleared or reduced to slow the spread of a wildfire and create a safe zone for firefighters to work. This space should be managed to reduce the risk of fire spreading to your home. By clearing away dead plants, trimming trees, and choosing fire-wise landscaping, you can disrupt a fire’s path and lower its intensity before it ever reaches your walls.

Follow key structural design standards

While building codes set the legal minimum for construction, WUI codes often include additional structural design standards that enhance fire resistance. These rules address the small details where a home is most vulnerable to embers. For example, codes will specify how to properly screen vents to prevent embers from getting into your attic or crawlspace. They also address the design of eaves, soffits, and decks, which can easily trap embers if not built correctly. These standards are crucial for ensuring that your home can withstand the unique challenges posed by wildfires, turning potential weak spots into well-defended features.

Your WUI Compliance Checklist: Key Areas to Cover

When you’re building or renovating in a wildfire-prone area, it’s helpful to think of your property as a complete system. Every component, from the roof to the driveway, plays a role in its defense. WUI codes aren’t just a bureaucratic hurdle; they’re a research-backed framework designed to give your home the best possible chance of survival. Getting these details right from the start protects your investment, simplifies the insurance process, and, most importantly, keeps you and your family safe.

Think of this as your high-level checklist for WUI compliance. These are the four core areas that local officials, insurance assessors, and fire professionals will focus on. By addressing each one in your building plans, you create multiple layers of protection against wildfire. We’ll break down what you need to look for in your home’s structure, its immediate surroundings, and the access routes that first responders will depend on in an emergency. Tackling these areas methodically ensures you’re not leaving any critical vulnerabilities in your home’s defense strategy.

Check your roofing and exterior walls

Your roof and walls are your home’s first line of defense against airborne embers, which can travel a mile or more ahead of a wildfire. That’s why WUI building codes are often much tougher than standard building codes, requiring specific, non-combustible materials. Your roof should have a Class A fire rating—the highest level of protection available. For exterior walls, materials like fiber cement, stucco, and treated wood are excellent choices. The goal is to create a non-flammable "shell" that can resist ignition from embers and radiant heat, preventing a fire from ever taking hold.

Inspect windows, doors, and vents

While your walls and roof form a shield, any opening can become a weak point. Embers are tiny and can easily enter your home through gaps in windows, doors, or uncovered vents, igniting it from the inside. WUI standards address this by requiring multi-pane tempered glass, which is more resistant to breaking under extreme heat. Door and window frames should be made from fire-resistant materials like metal or solid wood, not vinyl. Vents, including those for your attic and foundation, must be covered with a fine metal mesh (1/8-inch is a common standard) to block embers while still allowing for airflow.

Manage your landscaping and vegetation

What you plant around your home is just as important as what it’s built from. The area surrounding your house is known as "defensible space," and maintaining it is a core requirement of WUI compliance. This involves clearing flammable vegetation, dead leaves, and other debris for at least 30 to 100 feet around your home. Unfortunately, defensible space standards are sometimes misunderstood by homeowners, but they are critical for reducing the fuel a fire has to feed on. Creating this buffer zone can slow a fire’s spread and give firefighters a safe area to work.

Ensure clear access for emergency vehicles

If a wildfire approaches, can firefighters get to your home to defend it? WUI codes include specific requirements for property access to make sure they can. This involves having a driveway that is wide and sturdy enough to support a fire engine, with adequate vertical clearance from overhanging trees. Your address should be clearly visible from the street, even at night. Making sure emergency vehicles can easily get to and from properties is a non-negotiable part of a safe building plan. Without clear access, even the most well-built home may be impossible to protect.

How Do You Create Defensible Space Around Your Home?

Creating defensible space is one of the most effective actions you can take to protect your home from a wildfire. Think of it as a buffer zone you create between your house and the surrounding vegetation. This space is designed to slow or stop the spread of wildfire and protect your home from catching fire—either from direct flame contact or radiant heat. It also gives firefighters a safer area to work in if they need to defend your home.

The concept is based on a series of zones that extend outward from your house, each with its own set of recommendations. By managing the landscaping and materials within these zones, you can dramatically reduce your home’s vulnerability. It’s not about clear-cutting your property; it’s about creating a well-maintained, fire-resistant landscape. Understanding these zones is the first step toward building a home that can better withstand a wildfire. Many homeowners find that defensible space standards and WUI best practices are easier to implement than they first appear, especially when broken down into these manageable areas.

Zone 1: The immediate zone (0-5 feet)

This zone, also called the "non-combustible zone," is the most critical area of defense. It includes the area directly under and around your home, extending five feet out in all directions from the foundation. The goal here is simple: eliminate anything that can burn. This means clearing away all dead leaves, pine needles, and dry grass from your roof, gutters, and the ground. Use non-flammable materials like gravel, pavers, or concrete for landscaping right next to the house. Avoid planting flammable shrubs or placing bark mulch against the foundation. Think of this space as your home’s first line of defense against embers, which are a primary cause of home ignition during a wildfire.

Zone 2: The intermediate zone (5-30 feet)

In the space between 5 and 30 feet from your home, your focus should be on creating a "lean, clean, and green" landscape. This means interrupting the path of a potential fire by breaking up continuous vegetation. You don’t have to remove all your plants, but you should manage them carefully. Prune the lower branches of trees to create at least six feet of clearance from the ground. Space out trees and shrubs to prevent fire from jumping from one to the next. Regularly mow your lawn and clear away any accumulations of dead vegetation. These steps are often required by the Wildland-Urban Interface code, which sets rules for managing plants to reduce fire risk.

Zone 3: The extended zone (30-100+ feet)

This outermost zone extends from 30 feet to at least 100 feet from your home, or to your property line. The objective here is to further reduce a fire's energy and slow its spread. You don't need to be as aggressive with vegetation removal as in the closer zones, but you should still thin out trees and shrubs. Remove any highly flammable plants and get rid of dead trees or fallen branches. The goal is to create a landscape that transitions from your managed intermediate zone to the natural vegetation beyond. A well-maintained extended zone helps ensure that by the time a fire reaches your home, its intensity has been significantly reduced, making it much more defensible.

Choosing the Right Building Materials for WUI Zones

When you live in a Wildland-Urban Interface (WUI) zone, the materials you choose for your home are more than just an aesthetic choice—they’re your first line of defense against wildfire. This concept, known as “home hardening,” is a core principle of WUI building codes. It’s all about making your home stronger and less likely to catch fire from flying embers, which are the leading cause of home ignition during a wildfire.

Selecting the right materials isn't just about meeting the minimum requirements of your local building code. It’s about giving your home the best possible chance of survival. Fire-resistant materials can dramatically slow or even stop a fire from spreading to your structure, protecting your property and, most importantly, your family. These choices also have a direct impact on your ability to get and afford homeowners insurance. Insurers are increasingly looking at a home’s specific vulnerabilities, and a house built with fire-resistant materials is a much lower risk. From your roof to your deck, every choice matters. Let’s walk through the key areas where your material selection can make the biggest difference.

Use Class A fire-rated roofing

Your roof is the most vulnerable part of your home during a wildfire. It’s a large, exposed surface where embers can land and sit, potentially igniting the entire structure. That’s why WUI codes are so specific about roofing. You’ll need to use materials with a Class A fire rating, which is the highest level of fire resistance available. These materials are tested to withstand severe fire exposure without catching fire or allowing the fire to penetrate the roof deck.

Common Class A options include asphalt shingles, concrete or clay tiles, and metal roofing. The goal is to create a shield that stops embers from getting a foothold. A well-constructed, Class A-rated roof is one of the most effective investments you can make to protect your home.

Install non-combustible siding

After the roof, your home’s exterior walls are the next largest surface area exposed to wildfire. Siding made from flammable materials like untreated wood can easily ignite from embers or radiant heat from a nearby fire. WUI codes require siding to be made of non-combustible or ignition-resistant materials. This means choosing materials that don’t burn easily and can withstand high heat without catching fire.

Excellent choices for fire-resistant siding include fiber cement, stucco, brick, and stone. These materials create a protective shell around your home’s frame. While some treated wood products can meet fire-resistance standards, it’s crucial to verify their rating. Investing in non-combustible siding not only hardens your home against wildfire but also adds durability and can lower your insurance premiums.

Build with fire-resistant decking and fencing

A wooden deck or fence attached to your house can act like a fuse, carrying fire directly to your exterior walls. Because of this risk, WUI codes place a strong emphasis on the materials used for these attached structures. Your deck and fencing must be built with materials that are ignition-resistant or non-combustible. This is a critical part of creating a defensible space right up to your foundation.

Instead of traditional wood, consider using composite decking materials that have a Class A or B fire rating. Other great options include decks made from lightweight concrete or stone patios. For fencing, especially in the first five feet closest to your home, use non-combustible materials like metal or masonry. These choices help prevent fire from reaching your home and create a safer, more resilient property.

What Structural Features Must Meet WUI Standards?

When building or retrofitting a home in a wildfire-prone area, it’s easy to focus on big-ticket items like roofing and siding. But WUI codes go much deeper, addressing the small details of your home’s construction that can make all the difference during a fire. The primary goal is to prevent wind-blown embers from finding a way inside your home, as embers are responsible for igniting the majority of homes lost to wildfires.

Think of your home as a complete system. WUI standards ensure that every component, from the foundation to the peak of the roof, works together to create a hardened, fire-resistant structure. These codes address potential weak points where embers could get trapped or enter, such as vents, eaves, and the gaps under decks. By focusing on these structural vulnerabilities, you can significantly reduce the chance of your home igniting from within. A well-built home following these standards is designed to withstand an ember storm, giving it a fighting chance even when you’re not there.

Review foundation-to-roof construction

WUI codes provide a comprehensive roadmap for building a fire-resilient home. As one source puts it, these special rules "tell builders how to construct homes to resist fire from flames, heat, or flying embers." This means every part of the building process is considered, starting from the ground up. Your foundation must be properly sealed to prevent embers from getting into the crawl space. Exterior walls need to be built with non-combustible or ignition-resistant materials, and the assembly where the walls meet the roof must be designed to block ember intrusion. Following these holistic building principles ensures there are no weak links in your home’s defense.

Protect your eaves and soffits

Eaves (the part of the roof that overhangs the walls) and soffits (the underside of the eaves) are particularly vulnerable to wildfires. Their design can trap hot air and embers, creating a perfect spot for a fire to start and spread to the rest of your roof and attic. WUI codes require that eaves and soffits "be designed to block embers, often with fine screens." This typically involves "boxing in" open eaves and ensuring all vents—including those in the attic, foundation, and under the eaves—are covered with a fine metal mesh (1/8-inch is the standard). This simple step allows your home to breathe while keeping dangerous embers out.

Install a chimney spark arrester

If you have a wood-burning fireplace or stove, your chimney can pose a significant fire risk. It can act as an entry point for embers or, worse, release sparks that could ignite your roof or nearby vegetation. The International Code Council notes that spark arresters are devices "installed on chimneys to stop sparks from escaping and starting fires." A spark arrester is essentially a metal screen that fits over the top of your chimney flue. It’s a small, inexpensive addition that is required by the International Wildland-Urban Interface Code and is a critical part of making your home fire-safe.

How Can You Work Effectively with Local Fire Officials?

Navigating WUI codes can feel like a solo mission, but your local fire officials are one of your most valuable allies. Think of them as your partners in safety, not just enforcers. Their primary goal is to help you protect your home and community from wildfire, and they have the local expertise you need to do it right. Building a positive, proactive relationship with them from the start can make the entire process smoother and more successful.

Instead of waiting for an inspection or a notice, reach out to them as a resource. They can clarify confusing requirements, offer practical advice tailored to your property, and point you toward local programs or grants you might not know about. A collaborative approach ensures you’re not just checking boxes but making meaningful improvements that genuinely reduce your risk. By communicating early, keeping meticulous records, and understanding the specific rules for your area, you can turn a potentially stressful process into a confident step toward a safer, more resilient home.

Communicate early and often

Don’t wait until you’re deep into a building or landscaping project to get in touch with your fire department. Proactive communication is key because, as the Grand County Wildfire Council notes, defensible space and WUI building standards can sometimes be misunderstood. Reaching out early gives you a chance to ask questions and get clear, official guidance before you invest time and money. Call your local fire marshal or prevention officer and ask them to clarify the specific requirements for your property. This simple step can prevent costly rework and ensure your efforts align with what inspectors will be looking for.

Keep detailed records

Documenting your compliance efforts is crucial for both your local officials and your insurance provider. Remember, building codes represent the legal minimum, but your insurance carrier’s requirements are often much stricter. Create a file for your home that includes permits, inspection reports, receipts for fire-resistant materials, and before-and-after photos of your defensible space work. This "compliance portfolio" serves as clear proof that you’ve met your obligations. It’s an invaluable asset when speaking with inspectors and can make a significant difference when it comes time to secure or renew your homeowner's insurance policy.

Know your local code variations

WUI codes are not universal; they can change significantly from one county or town to the next. Your property’s specific location within a designated fire hazard severity zone will determine which rules apply to you. For example, strict defensible space enforcement might only apply to homes officially mapped within the Wildland-Urban Interface. Never assume the regulations are the same as in a neighboring community. The best source for this information is always your local fire department or county planning office. Check their websites or call them directly to confirm the defensible space laws and building standards for your exact address.

What Happens if You Don't Comply with WUI Codes?

Following WUI codes isn't just about checking boxes for a permit. It's about building a home that can stand up to the threat of wildfire and protecting your family and your investment. When you cut corners or overlook these requirements, the consequences can be serious, affecting everything from your physical safety to your financial stability. Unfortunately, many homeowners don't realize the full extent of the risks until it's too late. Non-compliance can put your home directly in harm's way, lead to frustrating legal and financial penalties, and even create devastating gaps in your insurance coverage when you need it most. Understanding these potential outcomes is the first step in making sure you're building a home that is truly resilient, insurable, and safe.

Risks to your safety and insurability

The most critical reason to follow WUI codes is simple: your safety. These regulations are designed to reduce the chance of your home igniting from embers or direct flames. When a home isn't built with fire-resistant materials or lacks adequate defensible space, it becomes a target. Unfortunately, many WUI best practices are misunderstood or overlooked by homeowners, leaving them unknowingly exposed. Insurance companies are acutely aware of this risk. If they see your property as non-compliant, they may refuse to offer a policy, increase your premiums, or even cancel your existing coverage, leaving you both physically and financially vulnerable.

Potential legal and financial penalties

Beyond the immediate safety concerns, ignoring WUI codes can lead to significant legal and financial headaches. Local authorities can issue stop-work orders on construction projects, forcing costly delays until the issues are fixed. You could also face hefty fines for non-compliance. In worst-case scenarios, you might be required to demolish and rebuild parts of your home that don't meet the standards. It's important to remember that building codes are the legal minimum, but failing to meet them opens you up to direct penalties that can drain your budget and derail your project timeline.

Gaps in your insurance coverage

Even if you have a homeowner's policy, non-compliance with WUI codes can leave you with unexpected gaps in your coverage. After a fire, an insurance adjuster will investigate the cause and extent of the damage. If they find that your home didn't meet required codes, they could argue that your negligence contributed to the loss and deny your claim. These kinds of common misunderstandings can leave you vulnerable to immense financial strain. Insurance carriers often have their own internal standards that are even stricter than local codes. Failing to meet these requirements means your policy might not provide the financial safety net you thought you had.

How to Stay Current with WUI Code Changes

Wildfire science and building technology are constantly evolving, and so are the codes designed to protect your home. Staying on top of these changes is not just about compliance—it’s about ensuring your defensive strategies remain effective year after year. Keeping informed requires a proactive approach, but knowing where to look makes it much easier. Here are a few reliable ways to stay current with the latest WUI requirements.

Follow local government resources

Your local fire department and county planning or building office are your primary sources for code updates. These agencies are responsible for adopting and enforcing the codes in your specific area, so their websites and publications are the official record. Because "defensible space standards and WUI building codes may be misunderstood," it’s best to get information directly from the source. This clarity helps you avoid costly mistakes based on outdated or incorrect advice. Look for newsletters you can subscribe to or public meetings you can attend. Following these official channels helps you cut through the noise and get accurate, timely information relevant to your property.

Look to professional associations for updates

For builders and architects, professional organizations offer another layer of insight. Groups like the National Fire Protection Association (NFPA) and the Insurance Institute for Business & Home Safety (IBHS) provide research, training, and updated best practices. Remember, "building codes are the legal minimum, but insurance carriers have their own, often stricter, requirements." Professional associations often share resources that address these higher standards, helping you design and build homes that are not only compliant but also resilient and insurable in high-risk areas. Their guidance can give you an edge in creating a truly fire-adapted home.

Get involved in your community

Your neighbors are one of your best resources. Participating in local workshops or joining a community group like a Firewise USA® site creates a space to share knowledge and experiences. A few "common misunderstandings can undermine your hard work and leave you unexpectedly vulnerable," but discussing plans with your neighbors can bring these issues to light. You can learn which contractors are familiar with WUI standards, what challenges others have faced, and how your collective efforts can create a safer neighborhood for everyone. Community engagement turns compliance from a solo task into a shared goal.

Keep Your Home Compliant: A Long-Term Plan

Meeting WUI codes isn’t a one-and-done task you check off when construction is finished. Think of it as an ongoing commitment to keeping your home and family safe. A strong long-term plan involves regular check-ins and proactive maintenance to ensure your property remains resilient year after year. By staying on top of these key areas, you can maintain your home’s defenses and adapt to any changes in local requirements.

Schedule regular property inspections

It’s easy to overlook compliance issues when you see your property every day. That’s why scheduling regular inspections—either by a professional or by using a detailed checklist yourself—is so important. Regular check-ups help you catch potential problems before they become serious risks. As the Grand County Wildfire Council notes, many homeowners may not fully understand defensible space standards, and inspections are a great way to stay informed and compliant. Treat it like an annual physical for your home’s wildfire safety, ensuring everything from your vegetation to your vents is still up to code.

Complete seasonal maintenance

Wildfire defense requires consistent effort, and seasonal maintenance is your first line of defense. Simple tasks like clearing dead leaves from your roof and gutters, trimming back overgrown shrubs, and removing flammable debris from under your deck can make a huge difference. This isn't just about keeping your yard tidy; it's a critical strategy for reducing fuel for a potential fire. As experts from Defensible Space Score point out, consistent seasonal maintenance is crucial for maintaining your defensible space and protecting your property from both fire and financial strain. Make it a recurring event on your calendar each spring and fall.

Get a professional plan review

If you’re planning a new build or a major renovation, remember that meeting the minimum building code doesn't automatically mean your home is insurable. Insurance carriers often have stricter requirements than local ordinances. This is where a professional plan review becomes invaluable. An expert can analyze your architectural plans to ensure they satisfy both legal codes and insurer expectations. This step provides critical peace of mind, confirming that your investment is not only built to last but is also properly protected before you even break ground.

Frequently Asked Questions

How do I know if my property is located in a WUI zone? The best way to find out is to check with your local authority. Your county’s planning department or your local fire district will have official maps that designate WUI areas and different fire hazard severity zones. A quick search on their website or a phone call is the most reliable way to confirm your property’s status and understand the specific rules that apply to you.

I have an existing home. Do I need to upgrade it to meet all the current WUI codes? Typically, you are not required to bring an existing home up to current code unless you are planning a major renovation, addition, or rebuild. However, voluntarily making fire-wise upgrades is one of the smartest things you can do. You can start with high-impact, lower-cost projects like creating defensible space, cleaning your gutters, and installing fine metal mesh over your vents to block embers.

Is it significantly more expensive to build a home that complies with WUI standards? While some fire-resistant materials can have a higher upfront cost than their standard counterparts, it's best to view it as an investment in your home's long-term safety and value. Building to these higher standards can reduce your insurance premiums and, most importantly, dramatically increases the odds that your home will survive a wildfire. The cost of compliance is minimal compared to the potential cost of rebuilding.

Will following these codes guarantee my home will survive a wildfire? Unfortunately, there are no guarantees in a severe wildfire. The goal of WUI codes is not to make a home fireproof, but to make it fire-resistant. By following these standards, you are hardening your home against the most common cause of destruction—wind-blown embers—and giving it a much better chance of survival. It’s about reducing risk and creating a structure that firefighters can more safely defend.

My insurance company has different requirements than my local building code. Which one should I follow? You should aim to meet the stricter of the two standards. Your local building code represents the legal minimum you must follow to get your project approved. However, your insurance carrier’s requirements determine your ability to get and keep an affordable policy. To be truly protected, both physically and financially, it's essential to build a home that satisfies both your building inspector and your insurance underwriter.
