Regulations at a glance

Local rules & notes

TRPA Coverage (IPES) Override: California state ADU laws do not override TRPA environmental coverage restrictions. ADU size and feasibility are strictly governed by the parcel's allowed land coverage. Development Right Requirement: Every ADU requires a 'development right' or 'building allocation,' which can be obtained via a Bonus Unit, a Residential Unit of Use (RUU), or by purchasing one on the open market. Two-Step Permitting Process: Applicants in the Tahoe Basin must receive a permit from TRPA first, and then a separate permit from their local jurisdiction (e.g., City of South Lake Tahoe or El Dorado County).

For the official ordinance and latest updates, check your city or county planning department.
