California adopted its Zone 0 rule on August 19. It is not in effect yet.
The Board of Forestry approved the statewide ember-resistant zone regulation, which requires a noncombustible fence span where your fence or gate meets the house. No statewide compliance deadline is running yet. Most of what's being mailed to homeowners about this is wrong: we read the regulation text, date every claim, and tell you what you actually need, and what you don't.
Where the rule stands: September 11, 2026
Statewide: adopted, then withdrawn from OAL. The Board approved the regulation on August 19, 2026 and filed it with the Office of Administrative Law on August 28. That filing was withdrawn on September 8, 2026, so the rule is not in effect, OAL neither approved nor disapproved it, and there is nothing in front of OAL now. Two further conditions sit in the statute and are easy to miss: the ember-resistant zone requirement does not take effect for new structures until the Board updates its guidance document as well as the regulations, and CAL FIRE may not change its inspection practices and forms until the State Fire Marshal posts a written finding that the Legislature funded the change. We looked for that finding and could not find it.
Withdrawn from OAL on September 8, 2026. The package was filed on August 28 as file number 2026-0828-03E, "Zone 0 Defensible Space", adopting Title 14 sections 1298.01 through 1298.04 and amending 1299.01 through 1299.03. OAL's record of actions on emergency regulations now carries that file as "Withdrawn, September 8, 2026", it is off the under-review table, and the Board has not refiled. A withdrawal is not a disapproval and not an approval: OAL decided nothing, so the regulation never reached the Secretary of State and has no effective date. Neither body has published a reason. The five-day public comment window ran from August 28 to September 2 and is over, and there is no longer a package at OAL for a comment to reach. The status tracker has the full record, including the ten-calendar-day arithmetic that puts the withdrawal on the day OAL's decision was due.
