ADU work in
Northridge.

Garage conversions in Northridge can be efficient when access is open and utilities are clear. Foundations, garage slab reinforcement, and utility trenching have to account for Valley floor clay, larger backyards, and older utility layouts. Plan check runs through LADBS 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 Northridge 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. Postwar tracts often have workable access but older plumbing routes. 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 Northridge homeowners.
