FireApproved.com CAL FIRE OSFM Building Materials Listing — WUI category censuses

Complete public censuses of the CAL FIRE Office of the State Fire Marshal Building Materials Listing, published by FireApproved.com. One census per in-scope category code, from a frozen snapshot. Every listing in a covered category is present — a census, not a selection.

• 276 listings across 16 category codes (decking, siding, doors, windows, vents, eaves, roofing, ignition-resistant and noncombustible materials, insulation, partitions, treated lumber, plywood).
• Each row keeps the listing ID, the product name as the listing records it, the BML application number, and the expiry. A row with no product page states why.
• croissant.json is Croissant 1.1, validated with mlcroissant.
• Canonical: https://fireapproved.com/data/
• Snapshot: https://github.com/grysngrhm-tech/fireapproved-data/releases/tag/v2026.08.25
• Coverage: California OSFM WUI listings issued 2026-03-19 through 2026-08-19, frozen 2026-08-25. Not a nationwide materials census.
• Methodology: https://fireapproved.com/methodology

Not a permit table and not a rating. A listing is a model record; local amendments govern, and the authority having jurisdiction decides what is accepted.

About FireApproved.com

Every wildfire plant list contradicts the next one, and almost none of them say why. One extension bulletin calls a shrub fire-resistant, the next calls it a hazard, and neither shows its work.

FireApproved.com is where you find out what is actually behind the advice. Look up a plant and you see every source that rated it, the exact words each one used, when it was published — and where they disagree, laid side by side instead of averaged into one anonymous verdict you have to take on faith.

It covers the whole decision, not just the planting list:

• 🌿 Plants — thousands of taxa with every cited rating, browsable by genus, by state and by USDA zone, each tracing to the source that rated it.
• 🏠 Materials — the vents, siding, decking, windows and roofing that are actually listed and tested, with the standards behind them and a lapse log for listings that have expired.
• 📍 States and requirements — what the code adopted where you live actually says, cited to the ordinance rather than to a summary of it.
• 📚 Guides — plain-language answers, from where to start to how to read a plant page, with a glossary for the terms the codes use.
• 🔎 Findings — the places where a test result or a jurisdiction contradicts what everyone repeats.

Why this data is worth citing

The site issues no rating of its own. Every status is computed from cited evidence by a published rule, and four properties make that reproducible:

1. Every verdict keeps the source's own words — its phrasing, its edition, and the date the document was read, not a label invented later.
2. Classifications are computed, never hand-assigned. See the methodology.
3. Evidence deduplicates by lineage, not by row. A rater who republishes the same finding in five places counts once, so a widely-copied opinion cannot outvote a laboratory result.
4. Conflicts are preserved, not averaged. When sources disagree the record says so and shows both sides.

The source registry ships alongside the evidence, so you can recompute or re-weigh every classification yourself rather than trusting ours.

The live site is the source of truth and is always current. Machine-readable entry points: llms.txt · llms-full.txt · every page has a JSON twin (the .json replaces the trailing slash).

FireApproved.com is a citation directory. It is not a listing body, an insurer, or a building official — verify at the source before you specify.
