Sacramento, California
ADUs are California's fastest-growing housing type — but every city has different rules for setbacks, size limits, and parking. Under state law (AB 68, AB 881), your city must approve a compliant ADU ministerially, but you still need to meet local zoning requirements for the primary structure and overall site. A single code miss can delay your permit by weeks.
California has some of the most permissive ADU laws in the country. Under AB 68 and AB 881, cities must approve ADUs that meet state standards — no discretionary review, no public hearings. But each city still has its own zoning code that determines setbacks, height limits, and lot coverage for the primary structure and site.
