Upside ADU builds junior adu (jadu)s in El Dorado Hills, El Dorado County, for a $1,000 deposit with transparent fixed pricing and inspection-tied payments. A typical El Dorado Hills junior adu runs $50,600–$184,000 all-in, and we permit it through the El Dorado County Planning & Building Department end to end.
El Dorado Hills rules that affect a junior adu
A junior ADU stays inside your existing El Dorado Hills home (up to 500 sq ft) with an efficiency kitchen and its own entrance, so it skips most setback and site-work questions. Note that JADUs carry an owner-occupancy requirement, which we confirm against El Dorado County rules.
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 junior 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 junior adu (jadu) page.
