Limited plants may be permitted in the 1–5 foot zone under strict conditions. They must be separated from walls, eaves, windows, vents, and other plants, and must be low-growing and low-combustibility. No plants of any kind are allowed within 1 foot of the foundation. Check with your local AHJ for approved plant lists.

Yes. Bark mulch, wood chips, and all organic mulch must be removed from within 5 feet of any structure. Inorganic alternatives like decomposed granite, gravel, river rock, or concrete pavers are permitted and recommended as ground cover replacements.

Individual potted plants may be permitted within Zone Zero under the August 19, 2026 final draft, provided they are separated from walls, eaves, windows, and other combustible materials. Potted plants must not be clustered and should be in non-combustible containers (ceramic, metal, or concrete, not plastic or wood).

Lawn grass is generally lower combustibility than mulch or shrubs and may be permitted under the August 19, 2026 final draft, particularly if kept green and mowed. Dead or dry grass must be removed. The foundation safety zone (0–1 foot) must be completely clear of all vegetation including grass.

In the August 19 text, existing structures have three years from the effective date for these landscaping items. The effective date does not exist yet — the package is in OAL review. New construction would comply on the effective date itself. Starting early is strongly recommended, as qualified landscapers in high-risk areas will be in high demand.

Basic removal like clearing mulch, pulling dead vegetation, and trimming trees can be done by homeowners. For tree trimming near structures, a licensed arborist is recommended. A licensed contractor can conduct a full Zone Zero assessment and document your compliance for your local AHJ.
