Poured concrete (Zone 0 hardscape)

This is a material class, not a wall or roof assembly listing. A class is not a permit.

Poured concrete slabs and walks are noncombustible hardscape in the first five feet. Landscaping guidance on this site names concrete alongside gravel, pavers, and stone. It is a material class, not an OSFM-listed assembly.

Kind: material-class. Page reviewed 2026-08-23. JSON (CC BY 4.0)

Zone 0 rules vary. California’s August 2026 Board of Forestry Zone 0 vote was not yet in force as of this verification.
Combustible formwork, wood sleepers, and stored fuel on the slab are not the slab.

Where this applies

A product is a national record; where it applies is a fact about a place. The rule that binds a given address — and every product matching it — is published on that place's own answer page, linked above and re-linked by the location lens. The complete per-place claim graph for this record, including every open official check, is in its JSON twin.
