Placentia, CA Short-Term Rentals: Host Platform Liability (2026)

Placentia Municipal Code Chapter 6.45 regulates short-term residential rentals, defined as the rental of a dwelling unit for a continuous period of 29 days or less. Section 6.45.020 defines a hosting platform as a person or entity that provides booking services and collects or receives a fee for them, and it also covers an online marketplace whose operator earns booking fees or advertising revenue from short-term rental listings. Facilitating includes simply allowing the offeror of a unit to advertise it on the platform's website.

Section 6.45.210 puts three duties on those platforms: do not facilitate rentals of unlicensed and illegal businesses, do not process transactions for properties that are not licensed and permitted by the city, and do not facilitate the evasion of taxes and regulations. Section 6.45.100(b) adds an advertising rule. No owner, managing agent, responsible party or hosting platform can advertise a short-term rental in the City of Placentia that is not licensed under the chapter. Before an owner lists a Placentia property, the platform must give that owner a notice stating that the chapter prohibits short-term rental of residential premises unless the city has issued both a business license and an operating permit and the owner pays transient occupancy tax. The operating permit number must appear on the platform's website wherever the rental is advertised, and each rental carries its own unique number. Section 6.45.100(a) also requires every advertisement, online included, to state the permit number and the number of occupants allowed.

Enforcement runs through administrative citations. Section 6.45.170(a) authorizes the city to cite a hosting platform for a violation of the chapter, and subsection (f) sets the fine for each violation of Section 6.45.210 at $1,000 per violation per day. Under subsection (b), each day or portion of a day that a violation exists is a separate violation, and citations, notice and appeals follow Sections 8.06.010 through 8.06.180 of the code. Section 6.45.010 declares any violation of the chapter a public nuisance punishable as a misdemeanor.
