ADU builders in Van Nuys

Van Nuys is the Valley's workhorse: deep, flat postwar lots, alley access, and a mix of single-family blocks and small multifamily. Deep flat lots are exactly what detached ADUs want, and the LADBS office that permits half the Valley sits in the middle of it.

Why Van Nuys homes bring this work to us

Van Nuys lots are deep, flat, and often alley-loaded — the exact geometry detached ADUs want. It's also LADBS's Valley home: the office that reviews your plans is up the street, and we're in it every week.

We're based in Mission Hills, so Van Nuys is home turf — walkthroughs usually happen within a couple of days.

What's included

ADUs we build in Van Nuys

Detached new-build ADUs

A complete small home in your backyard — foundation, framing, systems, and finishes, up to 1,200 sq ft under state law.

Garage conversions

The fastest, most affordable path to a rentable unit: foundation checks, insulation, systems, and a finish that doesn't feel like a garage.

Attached ADUs & JADUs

Additions and junior units carved from existing space, with the required separate entrance and kitchen done to code.

Guest houses & casitas

Not every backyard building needs a full kitchen — we build casitas, studios, and offices to the same standard.

Site work & utilities

Trenching, sewer connections, panel upgrades, and meters — the part of ADU budgets everyone forgets. We price it up front.

Plans, engineering & permits

Architectural plans, structural engineering, Title 24, and city plan check — or we build from the plans you already have.
