ADU builder
in Chatsworth,
CA.
Northwest Valley, with some of the largest lots in the area and pockets of hillside and semi-rural land against the Santa Susana foothills. Big lots leave room for a full-size detached unit; hillside sites bring grading, drainage, and access to plan for. Nexor handles design, permits, and construction under one fixed-price contract. No handoffs, no surprises.
Why ADU demand
is strong here.
Space is the Chatsworth advantage. Lots here can carry a full 1,200 sq ft detached ADU or a two-bedroom where tighter neighborhoods cannot. The hillside parcels need real engineering, which is exactly where a single design-build team beats a hand-off.
What will it
cost to build?
Select a type and size. We show our actual per-sq-ft rate from completed projects. Garage conversions are priced after a site visit because structural condition varies too much to quote blindly.
Under 600 sq ft: $235-$250/sq ft
600 sq ft and above: $222/sq ft

What the rules
actually say.
State law has made ADUs significantly easier to permit since 2020. Here is what applies to most Chatsworth parcels today.
We handle
the whole process.
Chatsworth is in the City of Los Angeles, permitted by LADBS. State law requires LADBS to approve or deny a complete application within 60 days. We file, respond to corrections, and track status so you never have to chase the building department.
Feasibility
Site visit, parcel map review, and a fixed-fee feasibility memo. You know setbacks, max footprint, and a rough cost range in two weeks.
Design
Schematic plans tailored to your lot, or a pre-approved Nexor plan set if you want to move fast. Four-week design block.
Permit
We file with LADBS and respond to every correction. Under state law, LADBS must approve or deny a complete application within 60 days. Pre-approved LA Standard Plans can clear in 21 to 30 days.
Build
Foundation to final inspection in 14 to 18 weeks. Weekly site reports. We hand you keys and a closing binder.

neighborhoods
we serve.
We build across Chatsworth and the surrounding Valley.
One contract.
One crew.
No handoffs.
Most ADU projects stall at the seam between a designer and a contractor. We do both. The team that draws your plans is the same team that pulls your permits and builds the unit.
Drawings match the build
When design and construction share the same team, field changes do not require going back to a separate architect and waiting weeks for a revision.
Fixed price, not an allowance game
What you sign is what you pay, unless you change the program. No allowance line items that blow up at selection time.
Weekly written reports
Your project manager sends a written update every Friday. You always know where the schedule stands.
