ADU builder
in Pasadena,
CA.
Older, architecturally significant housing stock, Craftsman and bungalow, much of it inside designated historic districts that shape what an ADU can look like. Nexor handles design, permits, and construction under one fixed-price contract. No handoffs, no surprises.
Why ADU demand
is strong here.
Pasadena has more designated historic resources than any city in LA County, so the design review is the defining factor here. A firm that handles the historic-district approval in-house, not through a hand-off, is the real advantage.
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
Estimated build cost for a 600 sq ft detached ADU. Design and permit fees are quoted separately.

Permitting in
Pasadena.
If your parcel is in one of Pasadena's 31 historic districts and the ADU is visible from the street, you need a Certificate of Appropriateness reviewing exterior materials, windows, siding, and roof form. The commission cannot block the ADU or add setbacks beyond state law; it shapes the visible design. We handle that review as part of the job.

we serve.
We build across Pasadena 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
