ADU builder
Agoura Hills.

ADU sites in Agoura Hills often sit between suburban pads and hillside rules. Foundations, garage slab reinforcement, and utility trenching have to account for foothill soils, oak-tree constraints, and Santa Monica Mountains edges. Plan check runs through City of Agoura Hills Building and Safety with Title 24 energy compliance and structural review on every permitted unit. Garage conversions often move faster than detached new-builds because the shell exists; hillside lots, tight side yards, and long utility runs can still add foundation and MEP cost. Most ADU construction in Agoura Hills lands in the $100,000-$300,000 range — garage conversions from $90k–$160k, detached units from $190k–$290k. Permit fees, utility connections, soils reports, and design are quoted separately by line item. Finish level, fire sprinklers, and separate utility meters are the usual cost drivers after site conditions. Old Agoura and Morrison Ranch can add HOA or rural access concerns. We coordinate HOA/ARC packets — exterior materials, parking replacement, access plans — in parallel with city submittals when they apply. We already build in your backyard. Here's what we handle for Agoura Hills homeowners.

We build pools and ADUs on the same lots across Southern California. When both are planned together, shared excavation, grading, and utility trenching often saves 10–15% versus separate projects.
