ADU rules in Elk Grove, CA — also called accessory dwelling unit regulations or granny flat ordinances — cover setbacks, owner-occupancy, parking, and permit requirements.
Elk Grove permits ADUs and JADUs on all residential lots per California Government Code §65852.2. EGMC Chapter 23.70 adopts the state standards: up to 1,200 sq ft detached ADUs, 4-foot rear/side setbacks, no owner-occupancy requirement, and streamlined ministerial permits within 60 days.
Elk Grove's ADU regulations are codified in EGMC Chapter 23.70 and comply with Gov Code §65852.2 plus AB 68, AB 881, SB 13, and AB 1033. Property owners may build one detached ADU, one attached ADU, and one junior ADU (JADU) on a single-family lot, subject to state ceilings. Ceiling standards the city cannot go below include: 800 sq ft and 16 feet in height with 4-foot side/rear setbacks (no matter lot size), up to 1,200 sq ft with local standards if the base limits are met, no replacement parking required within one-half mile of transit, no impact fees under 750 sq ft, and 60-day ministerial permit processing. JADUs are limited to 500 sq ft within existing single-family structures and require owner occupancy of either the main home or the JADU. AB 1033 (2024) allows ADU condo-ization so an ADU can be sold separately from the main dwelling. Elk Grove provides pre-approved ADU plan sets to reduce permit time.
Building an ADU without a permit: stop-work order, after-the-fact permit fees, and potential removal orders if safety or setbacks cannot be cured. Operating an ADU as a short-term rental may violate separate city STR rules.
