02 — Process
How Our Northridge ADUBuild Process Works
- 01
Site Assessment & Feasibility
We visit your Northridge property, assess your lot for ADU eligibility under current zoning, and discuss your program — how you plan to use the unit, what size makes sense, and what's achievable within your budget.
- 02
Design & Planning
We develop ADU plans that meet Northridge and Los Angeles code requirements. Setbacks, height limits, utility connections — all accounted for in the design before anything goes to the city.
- 03
Permitting
We manage ADU permit submissions with the City of Los Angeles. We know the process, the pre-approved ADU pathways, and how to respond to plan check comments without losing momentum on your Northridge project.
- 04
Construction
Foundation to finishes. Our team manages site work, framing, rough-in trades, and all finish work. Daily oversight keeps the project on schedule and on spec.
- 05
Final Inspection & Handoff
Final city inspection and walkthrough with you. Certificate of occupancy in hand. Your Northridge ADU is ready to rent, house family, or use however you planned.
