For journalists: what we track, what we have that nobody else does

Fact-checked August 23, 2026·Sources at the end of this article

Seven findings you can build a story on

Each of these is verified against primary text, and each links to the page that carries the full sourcing. Take the finding and go to the primary source; that is what the pages are for.

• Local rules already bind, and some are stricter than the state text. At least nineteen jurisdictions, from a fire district that started in 2019 to two desert cities this year. Paradise requires all fencing within five feet of any structure to be noncombustible, existing fences included, with a compliance certificate required before a sale closes. The register has every citation.
• Two cities reverse the state repair rule. The adopted state text expressly permits combustible repairs to an existing combustible fence. Indio and Indian Wells, by identical local amendments, require that replacing any part of a near-house fence run brings the entire run back noncombustible. A homeowner reading accurate coverage of the state rule would get the law in those cities exactly backwards. County page, with the ordinance text quoted.
• The statute under the five-year headline says three. SB 504 (Chapter 982, 2024), the statute nobody's history includes, set the existing-home lag at three years in both defensible-space codes. The adopted regulation matches that in the Local Responsibility Area and gives the State Responsibility Area five. The harmonising reading exists, and it is a construction, not something either text says. Tracked as an open question with the chaptered text quoted.
• The best fence sentence in print belongs to a local paper. We check published claims against the rule text on the corrections page, and it cuts both ways: the syndicated national claim that wood fences "must be replaced" fails on scope, extent and timing, while The Press Democrat's rendering is the most accurate we have found. When we have been wrong ourselves, the same page says so.
• Enforcement runs on education, and one town routed around that. The most recent reported year: 248,403 defensible space inspections, 3 citations. Paradise's point-of-sale certificate is the exception that does not wait for an inspector, because escrow does the asking.
• All fifty-eight county codes read, and local wildfire law lives in another era. We read the codified fire and vegetation law of every California county in a single survey: adoption dates run 1928 to 2008, the framework is thirty and one hundred feet, and outside the register's jurisdictions the five-foot idea appears in county law three times: a plan-check mandate in San Bernardino, an optional setback trade in Lassen, and one county code, Amador's, that names “Zone 0” just to recommend it. Three of the counties were read from Internet Archive captures of their blocked publishers' own pages, dated by the publishers' banners, two more through a print endpoint their login-gated publisher leaves open, and the last five from current text on August 23, 2026, including one county that publishes its own code as PDFs and one whose supposed publisher hosts nothing at all; the register's ledger tells each story plainly. The survey, with every citation on the register.
• Eight local codes may change meaning on the state rule's effective day, and nobody has told their residents. Calaveras, Contra Costa Fire and Morro Bay incorporate the state's defensible space regulation by reference; Mono, Inyo, Tehama and Alpine impose local duties that defer to the statutes the ember-resistant zone was written into, Alpine's expressly “as may be amended in the future”; and Kensington Fire Protection District points at the statutes, the regulation and their future amendments in one sentence, with recitals saying it intends Zone Zero alignment. On effective day, all eight may begin requiring Zone 0 through their own municipal codes, with no new vote and no announcement. We published the membership test, and the five near-misses we excluded, by name with reasons, so the list can be checked rather than trusted. Finding two of the survey, and every entry on our effective-date checklist.

What we will tell you that a source with a stake usually will not

• What the rule does not require. Existing unattached fences within five feet may remain under the state text. Repairs may use wood. The attached-fence requirement is a five-foot span, not a fence. We sell fence products, and we would rather you print what the text says than what a quote-hungry version of us would prefer.
• Which of our numbers is soft. The register count is a fact about how hard we have looked, not about California; we write "at least nineteen that we have verified" and never "there are nineteen." Counties surveyed: all fifty-eight, and the register carries the ledger of how.
• What we could not verify. Every county page carries a "claims we could not verify" section, and the register separates "checked, nothing found" from "unreachable," because a page that fails to load and a page with no fence provision produce identical search results.

How to check us, and how to cite us

Every substantive page carries a fact-check date and quotes its sources verbatim, with the citation under the quote. If you find a claim of ours that does not survive contact with the primary text, we want to know, and the correction will run on the page where the error was, dated. Cite us as The Zone Zero Report with the page URL; better still, follow our citation to the primary source and cite that.

For the statewide rule's status on any given day, the tracker is the page we keep current, including through the Office of Administrative Law filing window. If you are on deadline about whether Zone 0 is "law yet," that page is the answer, and it says exactly what is and is not pending.
