El Dorado Hills rules that affect a multigen adu
El Dorado Hills multigenerational builds are designed single-level and accessible — zero-step entry, wider doorways, curbless showers — so parents or adult kids live independently next door. El Dorado County permits these like any detached or attached ADU.
Local permitting: El Dorado Hills permits through the El Dorado County Planning & Building Department, not a city counter. Gated communities like Serrano and Blackstone add HOA design review, and larger custom lots often trigger septic, well, or grading review we scope before bidding.
That's the multigen adu-specific picture. For the full El Dorado County rulebook — every setback, height, and owner-occupancy detail — see our Sacramento-region ADU rules guide, and learn how the build type works statewide on our multigenerational adu page.
