Elk Grove caps residential lot coverage under Title 23, with typical single-family limits of 40-50% of lot area covered by structures. ADUs up to 800 sq ft are exempt from lot-coverage caps under Gov Code §65852.2.
Lot coverage in Elk Grove — defined as the percentage of a lot occupied by the footprint of buildings and covered structures — is capped by zone in Title 23. Most single-family zones (RD-4 to RD-7) limit total lot coverage to roughly 40-50%, with denser zones and smaller-lot products often allowing higher percentages. Covered patios, attached garages, and accessory buildings count toward lot coverage; uncovered decks below 30 inches tall and open pools generally do not. Under Government Code §65852.2, cities must allow at least an 800-square-foot detached ADU even if it would exceed the lot-coverage cap. Impervious surface (driveway, patio, walks) is regulated separately through stormwater standards rather than the lot-coverage cap.
