TimberTech® AZEK® Landmark Collection decking is listed for wildfire-area use in California as a deck-surface assembly.

CAL FIRE’s Building Materials Listing 8110-2042:0503 covers the Landmark assembly under SFM 12-7A-4A and shows an expiration date of June 30, 2027. The approval depends on the complete construction, so the board profile, fasteners, spacing, joists, and other installation details must match that listing and the manufacturer’s instructions.

A separate CAL FIRE listing, 8170-2042:0504, classifies Landmark and Vintage boards under ASTM E84 with an extended 20-minute test. That material classification is not a substitute for the deck-assembly listing.
