If your insurer asks for proof that your home is hardened, a contractor invoice only tells part of the story. The IBHS Wildfire Prepared Home designation is a third-party certificate that documents the whole system: roof, vents, the first five feet and the landscape around the house. Here is how it works in California and Nevada, what it takes, and what it can and cannot do for your policy.
What the designation is
Wildfire Prepared Home is a voluntary program run by the Insurance Institute for Business & Home Safety (IBHS), a research nonprofit. <br>
It was established in 2022 and is built on IBHS research into how homes ignite and which measures best prevent that. The program is now available in 14 states, including California and Nevada, after an April 2026 expansion.
A home earns the designation by completing a set of actions that address the roof, specific building features and the defensible space around the structure. It is all or nothing. IBHS says wildfire exploits the weakest link, so partial mitigation does not qualify.
There are two levels. IBHS recently renamed them, so you will see both sets of names online:
- Essential (formerly Base): focuses on wind-blown embers, which IBHS calls the leading cause of home ignitions. IBHS says most existing homes can be retrofitted to reach this level.
- Enhanced (formerly Plus): adds protection against direct flame contact and radiant heat. IBHS notes it is often achieved during new construction or major exterior renovations.
What Essential level requires
The requirements are specific and checkable, which is exactly why insurers and fire districts like them. Based on IBHS and Truckee Fire's summary, the Essential level includes:
- A Class A fire-rated roof covering
- Noncombustible gutters and downspouts
- Ember- and flame-resistant vents, or existing vents covered with 1/8-inch metal mesh
- Six inches of noncombustible siding or exposed concrete foundation at the base of exterior walls
- A noncombustible zone from 0 to 5 feet around the house and attached decks
- Maintained defensible space out to 30 feet, or to the property line if that is closer
The Enhanced level adds items such as noncombustible siding and decking, enclosed eaves, upgraded windows and doors, accessory structures moved at least 30 feet from the house, and removal of fencing that runs parallel to the home.
In June 2026, IBHS updated the home standard. The changes include revised tree and shrub guidance on spacing, trimming and placement, and clearer rules for decks and attached structures. If you read an older checklist, download the current one before you buy materials.
Who is eligible, what it costs, and how long it lasts
Eligibility is narrower than many people assume. The applicant must be the property owner. The home must sit on a permanent foundation, be three stories or fewer, and comply with applicable state and local wildland-urban interface building codes. Homes under active construction are not eligible.
The process, per IBHS:
- Complete the required mitigation work for your chosen level.
- Apply online and pay the nonrefundable application fee, which is $125.
- Upload photos of all four sides of the home, the 0 to 5 foot zone, and features such as decks, porches, pergolas, hot tubs and propane tanks.
- A third-party evaluation company verifies the documentation, and IBHS issues the certificate if the home qualifies.
A certificate is not guaranteed. The $125 covers the application only, not the work itself. IBHS notes mitigation costs depend on the condition of your home.
The designation is valid for three years. To keep it active, you complete a photo-based annual review in year one and again in year two, and you can apply to renew as the three-year mark approaches. Late reviews carry a fee. If you sell, the designation stays with the property and can be transferred to the new owner for a small fee.
This maintenance piece matters most in the first five feet. A certificate is only as good as the condition of your Zone 0 on the day someone checks. Our guide to the five-foot ember-resistant zone covers what to keep in that strip.
What it does for your insurance
This is where homeowners should be careful. The designation helps you document your home. It does not guarantee a policy, a renewal or a price.
Several carriers do reward it. Mercury Insurance, for example, lists potential wildfire-peril discount ranges for certified homes on its California wildfire mitigation page, and states that discounts, eligibility and renewal are subject to underwriting approval. An Insurance Journal report on the Mercury partnership noted that the discount applies to the catastrophe fire portion of the premium, not the whole bill. An analysis from Insurance for Good found that seven California insurers offer discounts for IBHS certification, and that the size of the discount varies widely by carrier. Some insurers offer none at all.
Sources also disagree on how the designation fits California's Safer from Wildfires regulation. Some county and industry pages describe it as part of that framework. The Insurance for Good analysis says it is not on the Department of Insurance's required list of measures, though some insurers offer discounts for it voluntarily. The practical takeaway: ask your carrier or broker directly whether they recognize the certificate, and how.
You also may not need the physical certificate to benefit from the work. Mercury's community resilience manager told Truckee Fire that insurer standards mirror much of what IBHS requires, and that homeowners making meaningful improvements can have those efforts considered in underwriting before the certificate arrives. Your carrier sets final pricing, and Wetline is not an insurance agent, so treat any figure you see online as a range to verify, not a promise.
In Nevada, the question is different. Wildfire exclusions are the bigger issue there, and documentation of mitigation can matter to carriers deciding whether to write a policy at all. Our piece on the Nevada wildfire exclusion explains what to check on your policy.
Local help in the Truckee and Tahoe area
If you live in the Truckee Fire Protection District, you have unusually good support. Truckee Fire has publicly encouraged residents to pursue the IBHS designation, says its staff will guide homeowners through the process at no cost, and has said it will reimburse the IBHS application fee for homeowners who earn the designation.
The district's Home Hardening Rebate Program reimburses up to 50 percent of eligible costs, with a maximum of $2,000. Rebates are paid after the project is completed and approved. To apply, you need a full-access defensible space inspection from Truckee Fire within the last 24 months, and all Zone Zero issues must be resolved first. Only existing, permitted structures qualify, so new construction, outbuildings and sheds are out. You can start by calling Truckee Fire at 530-582-7888 or scheduling an inspection at truckeefire.org/dspace. Details can change, so confirm current terms with the district.
Elsewhere around the lake, Living With Fire, the Tahoe-Nevada outreach partnership, hosted an IBHS Wildfire Prepared Home webinar in May 2026 with fire districts on both sides of the state line. Check with your local district to see whether it offers inspections or incentives.
What this means for your home
You do not have to decide today whether you want the certificate. You can work toward it in a sensible order.
- Start with the first five feet. Remove combustible mulch, plants, wood piles and stored items from the 0 to 5 foot zone, including under decks. It is the cheapest step and every checklist includes it.
- Fix the entry points for embers. Swap or cover vents with ember- and flame-resistant products or 1/8-inch metal mesh. Our vents and gutters service covers this work, including noncombustible gutters.
- Check your roof. A Class A roof is a baseline requirement. If yours is near the end of its life, plan the replacement so it also meets the standard.
- Get an assessment before you apply. A free home hardening assessment can show which Essential items your home already meets and which are gaps. For the program overview, see our page on the Wildfire Prepared Home designation.
- Use local programs. Truckee-area owners should start with a district inspection and rebate. See our Truckee page for local context.
- Keep records. Save dated photos, invoices and product specifications. Insurers and evaluators both ask for them.
- Call your carrier or broker before you spend. Ask whether they recognize the IBHS designation, what documentation they want, and when they apply mitigation credits. Your carrier sets final pricing.
Frequently asked questions
Is the Wildfire Prepared Home designation available in Nevada?
Yes. IBHS lists Nevada among the 14 states where the program is available, alongside California. The eligibility rules are the same: owner-applicant, a permanent foundation, three stories or fewer, and compliance with local wildland-urban interface building codes.
How much does the designation cost?
The IBHS application fee is $125 and is nonrefundable. The larger cost is any mitigation work your home needs, which varies by condition. Some local programs offset it, such as Truckee Fire's rebate of up to $2,000 and its reimbursement of the application fee for homeowners who earn the designation.
Will the designation lower my premium?
It may, but there is no guarantee. Some carriers offer discounts for certified homes, others do not, and the amount varies. Discounts are generally tied to the wildfire portion of the premium and are subject to underwriting approval. Ask your carrier or broker what they recognize, and remember that your carrier sets final pricing.
