Oregon is changing how it builds homes — and the Oregon Coast and Central Oregon are at the center of that shift. The State of Oregon has adopted Section R327 of the Oregon Residential Specialty Code (ORSC), a comprehensive set of wildfire hazard mitigation standards that local municipalities can adopt by ordinance. As of April 1, 2026, Deschutes County and the City of Sisters have made R327 mandatory for all new residential construction — and the City of Bend is actively moving toward adoption. For homeowners, builders, and buyers from Brookings on the Southern Oregon Coast to the high desert of Central Oregon, this is one of the most consequential changes to residential construction in a generation.

Oregon's Statewide Wildfire Building Code Movement

The State of Oregon's Building Codes Division (BCD) developed R327 in direct response to Oregon's escalating wildfire losses — most dramatically the 2020 Labor Day fires that destroyed more than 4,000 Oregon homes in a single catastrophic week. The code is built into the Oregon Residential Specialty Code and is available for any municipality in the state to adopt locally by ordinance. Oregon's BCD describes home hardening as steps that "decrease the likelihood that a nearby fire will ignite your structure, and reduce the potential for damage" — and emphasizes that fire hardening "makes the community more resistant to the spread of wildfire" by slowing fire spread and creating additional time for emergency responders.

Critically, R327 is not limited to Central Oregon. The Oregon BCD explicitly states that home hardening measures "may be voluntarily followed for new construction, and when replacing exterior elements of existing construction" throughout the entire state — including the Oregon Coast. Whether you are building a new home in Gold Beach, remodeling a coastal cottage in Brookings, or replacing the roof on a property near Coos Bay, R327 standards provide a clear, state-endorsed roadmap for reducing your wildfire risk.

The municipalities that have formally adopted R327 by ordinance as of April 2026 are Ashland, Deschutes County, Grants Pass, Medford, and Sisters. Bend is actively pursuing adoption. This growing list reflects a statewide recognition that wildfire risk is no longer confined to remote rural areas — it is a present and growing threat in Oregon's cities, suburbs, and coastal communities alike.

Why the Oregon Coast Is Not Exempt from Wildfire Risk

Many Oregon Coast homeowners assume that the region's maritime climate — its fog, rainfall, and proximity to the Pacific — provides natural protection from wildfire. That assumption is increasingly dangerous. The Oregon Coast Range contains dense conifer forests that can carry fire rapidly under the right conditions. The 2020 Labor Day fires burned through portions of Lincoln County and Lane County on the Coast Range, and the Chetco Bar Fire of 2017 burned more than 190,000 acres in Curry County — right in Gerald Ross Agency's home territory near Brookings and Gold Beach.

The insurance industry has taken notice. Carriers writing homeowners insurance in Curry County, Coos County, and Douglas County are applying wildfire risk models that increasingly flag coastal properties in the wildland-urban interface (WUI). Homes built with older materials — wood shake roofs, single-pane windows, open eave vents — are receiving heightened scrutiny at renewal, regardless of whether they are located in Bend or Brookings.

What R327 Requires: The Six Core Components

R327 focuses on the exterior components of a home most vulnerable to wildfire ignition — the surfaces and openings that embers, radiant heat, and direct flame contact first. Deschutes County has accepted the CalFire Building Materials Listings and Wildland Urban Interface (WUI) Listed Products Handbook as a compliance reference, making product selection more straightforward for builders. Many of the required materials are already common in modern construction.

What R327 Applies To — and What It Does Not

R327 applies exclusively to structures governed by the Oregon Residential Specialty Code — new one- and two-family dwellings and newly constructed accessory structures such as garages and shops. It does not apply to commercial buildings, apartment buildings, or mixed-use structures. It also does not apply to existing homes, remodels, additions, or non-habitable detached accessory structures under 400 square feet with a maximum roof height of 15 feet.

Defensible Space: The Other Half of the Equation

R327 focuses on the structure itself — but home hardening alone is only part of the picture. Defensible space is the cleared buffer zone around your home that slows or stops fire spread and gives emergency responders room to work. The City of Bend is addressing defensible space requirements separately from R327, recognizing that it involves multiple city departments and broader community input. For existing homeowners throughout Oregon — including the Oregon Coast — maintaining defensible space is one of the most impactful steps you can take right now, regardless of whether your home was built to R327 standards.

What R327 Means for Your Oregon Insurance

The insurance industry has been watching Oregon's wildfire building code adoption closely — and the implications are significant for homeowners across the entire state. Carriers that have been tightening underwriting in high-risk areas are increasingly factoring construction quality into their decisions. A home built to R327 standards is a materially different risk profile than one built to older codes, and that difference is beginning to show up in coverage availability and pricing from the Oregon Coast to the Cascades.

For existing Oregon homeowners — whether you are on the Southern Oregon Coast in Brookings or Gold Beach, in Coos Bay, or in the Central Oregon communities of Bend, Sisters, or Prineville — voluntary compliance with R327 measures is a smart investment. Replacing aging roofing with Class A materials, upgrading to ember-resistant vents, or installing dual-pane windows can be presented to your carrier as documented risk mitigation improvements. Some insurers will credit these upgrades at renewal. It is worth discussing with your agent before your next renewal date.

If you are purchasing a newly constructed home in Deschutes County or Sisters, ask your builder to confirm R327 compliance in writing and request documentation of the materials used. This documentation can be valuable when shopping for homeowners insurance or at renewal — carriers increasingly want to see evidence of construction quality, not just a general description.

Our Take: What This Means for Oregon Coast & Central Oregon Clients

At Gerald Ross Agency, we have been serving Oregon homeowners since 1937 — from our Brookings office on the Southern Oregon Coast to our Bend and Prineville offices in Central Oregon. We have watched the wildfire insurance market tighten dramatically over the past five years, and we are already seeing carriers look closely at wildfire mitigation as a factor in underwriting decisions across all three of our service regions.

R327 is not just a building code — it is the insurance industry's emerging benchmark for what a "well-built" home looks like in Oregon's wildfire era. Whether you are building, buying, or simply renewing your existing policy, understanding R327 and taking voluntary steps toward compliance puts you in a stronger position with carriers. We work with more than 50 insurance carriers and can help you find coverage options that reflect the actual risk profile of your home — not just a ZIP code.
