Corrections
Every factual correction this site has made, newest first, taken from the dated note on the page where it was made. If we got something wrong, this is where it is written down.
This index is generated from those notes rather than kept by hand, so it cannot list a correction the site does not make, and it cannot quietly drop one. Each entry links to the page so you can read the note in context.
Not to be confused with a different page. This one is about errors we published. What the Zone 0 coverage gets wrong is about errors other people publish, claim by claim.
Why this page exists. This site's subject is other people's stale and inaccurate claims about a rule that keeps moving. A publication that corrects everyone except itself is not worth reading. So corrections are made in the text with a dated note, the original wording is quoted rather than deleted, and nothing is edited quietly.

September 1, 2026: San Diego's Zone 0 fence ordinance is already in force. Here are the real deadlines
Correction, September 1, 2026. This section used to open "San Diego's ordinance allows two things the state regulation does not." The ordinance does not. We read San Diego Municipal Code §512.0604 in full today, and the only fence in it is a setback-reduction clause about noncombustible block walls. The two allowances below come from the City's Zone 0 Guidelines for Existing Structures, the same guidance document quoted above, and the guidelines attach conditions we had left out. Our August 31 addition naming three treated-lumber products sat under the old heading, so it compounded the error rather than inheriting it.
September 1, 2026: What counts as a noncombustible fence material (and what fails)
San Diego is the one major jurisdiction with an in-force Zone 0 ordinance (SDMC §512.0604, in force for new structures since February 28, 2026, with the existing-structures phase beginning February 28, 2027) whose materials rules are more permissive than the adopted state regulation. The permissive rules are not in the ordinance, which names no fence material: they are in the City's Zone 0 Guidelines for Existing Structures (rev. April 22, 2026), which say of themselves that they are not enforceable until February 28, 2027 and are subject to change. Corrected September 1, 2026; we had attributed them to the ordinance. The guidelines allow:
August 31, 2026: What counts as a noncombustible fence material (and what fails)
Correction, August 31, 2026: a fence can hold a state listing The paragraph above used to go further than that, and it was wrong. Until today this page said there was "nothing to certify against" and that no fence product from any manufacturer could carry a certification. The three empty registries are real, and we still stand behind them. The conclusion we drew from them does not follow.
August 30, 2026: Zone 0 in Santa Barbara County: who requires it, and who pays for it
The Board of Supervisors does have a Zone 0 provision, and we said it did not. It is not in the county's fire code, which is where we looked; it is in the county's separate wildland-urban interface code, adopted November 18, 2025. Corrected August 30, 2026, and set out below.
August 29, 2026: Zone 0 in Ventura County: what applies where
Unincorporated Ventura County: still unread, and we had the wrong document. Corrected August 29, 2026. We described Ventura County Resolution No. 25-116 as the county's own ratification. Reading Port Hueneme's staff report, it is not a ratification at all: it is the findings resolution that Health and Safety Code section 13869.7 requires the district to make about local climatic, geological and topographical conditions, adopted by the VCFPD Board of Directors on September 16, 2025. Resolution 25-116 is attached to that packet as a scanned image with no readable text layer. We have since read it from a different packet, Moorpark's, whose scan of the same document does carry a text layer; it is set out in full...
August 29, 2026: Zone 0 in Riverside County: what applies where
Beaumont is now a row, and we had the wrong ordinance. Corrected August 29, 2026. We previously said here that Beaumont's code publisher "records Ordinance No. 1196 as adopted on December 16, 2025," and that we had read a draft and a citation rather than the adopted chapter. The draft part was right and the citation was wrong. Beaumont's codified Chapter 15.20 exists, carries Section 604.11 in full, and its Editor's note names a different instrument:
August 25, 2026: Where Zone 0 is already law: every California jurisdiction with rules in force
Corrected August 25, 2026. This section used to be headed "twenty-six jurisdictions, twenty-six different rules." That is a quotation of what we used to say, kept at the number we said it at, and it is not what we found when we went looking properly.
August 24, 2026: Zone 0 in San Diego County: what applies where
No adopted Zone 0 ordinance of their own was found for the cities of Escondido, San Marcos, El Cajon, Chula Vista, Carlsbad or Poway as of August 16, 2026. Corrected August 24, 2026: this list previously included Fallbrook and Ramona, which are unincorporated communities rather than cities, and are therefore covered by the county Consolidated Fire Code described above rather than needing an ordinance of their own.
August 24, 2026: Zone 0 in Riverside County: what applies where
Corrected August 24, 2026. This summary used to end by saying that "nothing in force here touches the five-foot ember zone," which was true when we wrote it and has been wrong since the county adopted Ordinance 787.11. The county still enforces 100-foot defensible space and hazard abatement, and it now also enforces a Zone 0 fence rule, as do five of its cities. If you are in unincorporated Riverside County, that includes Idyllwild, Pine Cove and Mountain Center.
August 24, 2026: Does Zone 0 apply to your home? SRA, LRA and hazard maps decoded
Correction, August 24, 2026. This paragraph used to say that Escondido, San Marcos, Fallbrook, El Cajon, Chula Vista, Carlsbad, Poway and Ramona were "separate jurisdictions without such an ordinance." That was two errors in one sentence. Fallbrook and Ramona are not cities at all; they are unincorporated communities, so the instrument that governs them is not a city ordinance but the County of San Diego's Consolidated Fire Code, working through their fire protection districts. And that code has carried a Zone 0 section since April 13, 2023, requiring the first five feet to be "continuous hardscape or non-combustible materials," with mulch prohibited. So the honest statement is that the incorporated cities...
August 23, 2026: Zone 0 in Riverside County: what applies where
Correction, August 23, 2026. This section previously said we had found no adopted Zone 0 ordinance "from Riverside County or from any city in the county". That was accurate when we wrote it and it is not anymore, because we kept looking: Indio and Indian Wells both carry Zone 0 fencing rules in force, adopted as local additions to the 2025 California Wildland-Urban Interface Code. We found them by searching code libraries for the operative language rather than by checking agency websites, which is how the first pass missed them.
