Why ADU demand
is strong here.

Proximity to CSUN creates steady rental demand from faculty and graduate students. The postwar grid means consistent lot depths and few irregular parcels, which keeps feasibility straightforward on most sites.

California state law

What the rules
actually say.

State law has made ADUs significantly easier to permit since 2020. Here is what applies to most Northridge parcels today.

AB 68 + AB 881
Approvals are ministerial. If your project meets objective standards, the city must issue the permit. No discretionary hearings, no neighbor sign-off.
SB 13
Impact fees are waived on ADUs under 750 sq ft, saving you $10,000 to $40,000 compared to a standard new-construction permit on the same lot.
AB 976
Owner-occupancy is not required. Build, rent, and never live on the property.
SB 897
Attached ADUs may reach 25 feet in height, which allows a second-story addition on many existing single-family homes.
AB 1332
Cities must maintain a library of pre-approved ADU plans. We use pre-approved sets when they compress your permit timeline.
AB 68
Junior ADUs up to 500 sq ft are allowed inside the existing home or an attached garage on any residential-zoned parcel statewide.
Permitting in Northridge

We handle
the whole process.

Northridge 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.

02

Design

Schematic plans tailored to your lot, or a pre-approved Nexor plan set if you want to move fast. Four-week design block.

03

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.

Why it matters

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.
