Isleton, CA Short-Term Rentals: Occupancy Limits (2026)

The City of Isleton (population ~800) is a small Sacramento River Delta city whose Municipal Code, accessible through the Municode Library and Isleton's zoning code (Appendix A), does not include a stand-alone short-term rental, vacation rental, or transient occupancy chapter as of this writing. Article 13 (General Provisions and Exceptions) and Article 12 (Home Occupations; Manufactured and Second Housing Units) do not address STR occupancy. Because there is no local STR-specific cap, overnight occupancy in an Isleton STR defaults to (1) the general residential occupancy standards in the California Building Code and California Residential Code (CRC R304 minimum-room-area rules), and (2) California Health & Safety Code § 17920.3, which addresses substandard housing and overcrowding. The widely used informal benchmark drawn from the federal HUD/Keating Memo standard - two persons per bedroom plus one additional occupant - is commonly applied by code enforcement and platforms in jurisdictions without a local cap. State law also requires hosting platforms to display the relevant local STR rules; where (as in Isleton) there are no local caps, the platform's posted maximum and the property's bedroom count typically govern. Operators should also confirm whether their property is in unincorporated Sacramento County rather than within Isleton city limits, because Sacramento County does have its own STR rules in unincorporated areas.
