CanIBnBCalifornia STR Rules
Methodology

How we verify

Where a rule comes from

Every rule line on this site carries a verification level, the date it was checked, and a citation. The levels mean exactly this:

Level 1Quoted from the live municipal code text or the adopted ordinance PDF. Headline rules show the code's own sentence, in quotation marks, with the section number.
Level 2From the city's or county's official page or application materials, when the code text itself could not be read. The page says so.
Level 3From a secondary source such as news coverage, clearly labeled, used only when nothing official is readable. We do not publish a full page on level 3 alone.
Level 0Not verified. No page is published; a short holding note says what we could not read and how to ask the jurisdiction directly.

Where a jurisdiction says it is unregulated, that absence was verified, not assumed: the code's table of contents, the zoning use tables and definitions, and the transient occupancy tax chapter were each checked for short-term rental provisions.

How the work is done

Research is AI assisted and human reviewed. Automated researchers read the publishers' code libraries and official pages under fixed rules: quote the operative sentence verbatim or record the field as unknown, never fill a fact from memory, and never present a pending ordinance as current law. The CanIBnB research desk reviews records before they publish, and a build check refuses any page that lacks its citations, quotes, dates, or error link.

Records are re-checked on a rolling schedule. A page whose sources have not been re-checked in six months shows a notice saying so. Pending amendments appear in their own box, marked proposed and not in effect, with the council date.

What we do not cover

We verify government rules: state law, city and county ordinances, and official permit registries. We do not check private restrictions. HOAs, CC&Rs, condo associations, and lease terms can prohibit short term rentals even where the city allows them. Before buying or renting, confirm with the HOA or review the CC&Rs for the specific property.

When we are wrong

Every page has a Report an error link. A confirmed error is fixed within a week and recorded in the public corrections log with the date. Rules change and cities amend ordinances; if the code and a city's own page disagree, the page says which says what.
