What Jefferson County’s wildfire code means for Pine-area projects
Jefferson County’s wildfire code took effect July 1. Pine-area owners should check the WUI map before filing permits for additions or exterior work.
Jefferson County’s Wildfire Resiliency Code took effect July 1, 2026. For property owners in and around Pine, the practical question is whether a parcel is in the county’s mapped Wildland-Urban Interface and whether the planned work requires a permit.
The rules do not apply automatically to every property with a Pine mailing address. Pine is addressed here as an unincorporated Jefferson County community or area, and the code applies only to qualifying work on unincorporated county parcels within the mapped WUI.
Permit timing matters
The code applies to permits submitted on or after July 1, 2026. Applications submitted before that date are governed by the codes and regulations in effect when they were filed. The rule is tied to the permit application date, not the date construction is completed.
Jefferson County’s map identifies WUI Class 1 areas in blue and Class 2 areas in orange. Class 1 includes Interface Perimeter and Interface Interior areas. Class 2 is the Wildland-Urban Intermix and carries additional structure-hardening and defensible-space requirements because the county identifies it as a moderate- to high-fire-hazard area.
Which Pine-area projects may be covered?
The code applies to construction, exterior alterations, movement, exterior repair and replacement of buildings or structures within mapped WUI areas. Examples listed by the county include new construction, additions, deck replacements, re-siding and re-roofing.
The requirements generally apply to the part of the building being changed rather than automatically requiring the entire existing structure to be rebuilt to current standards. Depending on the project and WUI class, the rules address roofing, gutters and downspouts, ventilation openings, exterior walls and siding, windows and doors, decks, eaves, soffits and other structure-hardening features.
New buildings and additions may also trigger defensible-space requirements. The county describes three zones measured from a structure: Zone 1 from 0 to 5 feet, Zone 2 from 5 to 30 feet, and Zone 3 from 30 to 100 feet. Zone 3 requirements apply only in Class 2 areas.
For applicable defensible-space work, the county generally requires the property owner to hire a county-approved Wildfire Mitigation Specialist for an initial inspection and a final inspection after the work is complete. The county says there is no county fee for defensible-space work, but the owner is responsible for the specialist’s services. A limited self-inspection and owner attestation may be used for re-siding projects that require only Zone 1 standards.
Some work is exempt
The code exempts alterations that affect only the interior of an existing structure, such as a kitchen remodel. It also lists exemptions for certain exterior wall or roof work affecting less than 25% of the applicable surface area, other minor exterior repairs, painting and similar maintenance, some detached accessory structures of 120 square feet or less, qualifying agricultural barns and fences located more than 8 feet from a structure.
Those exemptions are technical. A full roof replacement, for example, is not treated the same as a roof repair affecting less than 25% of the roof area: the county says a full re-roof in the WUI must meet applicable roofing standards, but no defensible-space work is required for re-roofing under the code. An exemption from the wildfire code also does not authorize work that violates other county requirements.
How to check a Pine-area property
Use Jefferson County’s interactive WUI parcel map to see whether a property is mapped in Class 1 or Class 2. The county says blue parcels are Class 1 and orange parcels are Class 2. The county’s PDF overlay map can provide broader context, but a parcel-specific map check is the better starting point.
Property owners who need help interpreting a parcel or project should contact Jefferson County Planning and Zoning. The county map is a screening tool, not a substitute for a parcel-specific determination by county staff.
For Pine-area homeowners, builders and property buyers, the practical step is to check the parcel and project scope before submitting plans. The new requirements are tied to mapped WUI coverage and permit timing—not simply to living in Pine.
