ADU builder
Pasadena.

ADU builds in Pasadena are shaped by older homes, mature trees, and a city permit process separate from LADBS. Foundations, garage slab reinforcement, and utility trenching have to account for older alluvial soils, landmark homes, and tight access in historic districts. Plan check runs through City of Pasadena Permit Center 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 Pasadena 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. Bungalow Heaven and Linda Vista projects may have design review or preservation limits. 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 Pasadena 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.
