ADU rules in Truckee, CA — also called accessory dwelling unit regulations or granny flat ordinances — cover setbacks, owner-occupancy, parking, and permit requirements.
Truckee Development Code Section 18.58.025 (effective December 10, 2024) governs ADUs. Detached or attached ADUs up to 800 sq ft and 16 ft tall qualify for reduced 4-foot side and rear setbacks; larger ADUs follow the zoning district's standard setbacks.
Under DC 18.58.025, an ADU must include permanent provisions for living, sleeping, eating, cooking, and sanitation on the same parcel as a single-family or multifamily dwelling. ADUs are not permitted between the primary residence and the front property line unless they qualify as a smaller ADU. Smaller ADUs - up to 800 sq ft gross floor area and 16 ft height from natural grade - may be located as close as 4 feet to side and rear property lines (including eaves). Larger ADUs must meet the underlying zoning district setbacks per DC 18.26. Owner occupancy and short-term rental restrictions track California state law (Gov't Code 65852.2): a detached ADU cannot be rented short-term separately from the main dwelling (TMC 5.02; DC 18.58.220.F).
Building or occupying an ADU without a permit is enforced as a building code violation under TMC Title 15, with citations, stop-work orders, and required permit retroactivity. Illegal short-term renting of a DLA/ADU triggers STR fines up to $5,000/day per TMC Ch. 5.02.
