ADU builder
Irvine.

ADU projects in Irvine are usually less about hillside engineering and more about HOA standards and tight staging. Foundations, garage slab reinforcement, and utility trenching have to account for planned-community pads, HOA design rules, and compact access in newer tracts. Plan check runs through City of Irvine Community Development 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 Irvine lands in the $115,000-$330,000 range — garage conversions from $105k–$170k, detached units from $220k–$340k. 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. Many Irvine villages require HOA approval before city permits. 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 Irvine 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.
