Building on Raw Land in Coconino County, Arizona

The Firewise three-zone system: what the ordinance actually requires around a structure

Coconino County's Zoning Ordinance (Section 4.4.E, Fire Protection and Weed Mitigation) requires any subdivision or development needing a landscape plan within the Wildland-Urban Interface to follow Firewise defensible-space zones keyed to distance from the structure. In the zone closest to the building, the rule is to clear native brush from under trees, trim trees so the lowest branches sit above roofline height, and keep tree canopies at least 10 feet apart. Moving outward, the requirement shifts to removing ladder fuels -- vegetation that lets fire climb from the ground into tree canopies -- by keeping the lowest branch at least three times the height of nearby shrubs and trimming tree limbs to a minimum of 6 feet off the ground. This is layered on top of the countywide Wildfire Defense Ordinance itself (most recently Ordinance 2024-01, replacing a 2022 version), which governs broader defensible-space and fire-restriction obligations for private property in the unincorporated county.

Separate fire districts can go further on their own authority. The Sedona Fire District, for one, has adopted the 2018 Wildland-Urban Interface building code with its own additional fire-suppression construction requirements. If you're building anywhere in forested or high-elevation Coconino County -- which covers most of the county outside the high desert near the Grand Canyon -- confirm with Community Development both the current version of the county wildfire ordinance and whether the parcel sits inside a fire district (like Sedona's) layering its own building-code requirements on top.

A documented, worsening insurance problem -- and Arizona has no FAIR Plan to fall back on

Coconino County government maintains its own dedicated public page, "The Wildfire Insurance Crisis in Coconino County," acknowledging that many residents face sharply rising premiums or outright non-renewal of homeowners' coverage because of wildfire risk -- some private carriers have stopped writing fire coverage in high-risk parts of the county entirely. This isn't anecdotal: a University of Arizona Cooperative Extension bulletin (az2170, October 2025), "Wildfire & Homeowners' Insurance Non-Renewals in Arizona," compiles newly available statewide data comparing non-renewal rates to wildfire activity over time, and identifies Coconino County -- along with Navajo and Greenlee counties -- as one of the northern Arizona counties with a sharp spike in non-renewals following major fire seasons. An independent, ten-month investigation by Arizona's Resiliency and Mitigation Council reached similar conclusions about rising premiums and elevated non-renewal rates statewide.

The structural problem for a Coconino buyer is that Arizona, unlike California or Oregon, has no state-run FAIR Plan -- the insurer-of-last-resort program those states use to guarantee basic fire coverage when the private market pulls back. When a standard carrier declines or drops a Coconino property, the fallback is a surplus-lines carrier (an unregulated, non-admitted insurer that can charge more and offer thinner terms than an admitted carrier) or, in the worst case, going without fire coverage entirely. For anyone building or buying forested or high-elevation land here, get a specific insurance quote for the actual parcel before finalizing a purchase or construction budget -- don't assume standard-market coverage and pricing will be available just because a neighboring, lower-risk property has it.

What this means for financing and budgeting a build

A construction loan or mortgage typically requires proof of hazard insurance before closing, so an insurance gap isn't just a cost problem -- it can be a financing blocker. If a lender's underwriting depends on a specific coverage type or price point that turns out to be unavailable for a high-wildfire-risk Coconino parcel, that can delay or derail a purchase or construction loan late in the process. Get a firm insurance quote (not just an estimate) for the specific parcel and structure plan early, ideally before waiving a financing or inspection contingency, and ask your lender directly whether they have experience underwriting in Coconino's wildland-urban interface areas.
