Garage Conversion in Van Nuys, CA

ADU or living space?

Van Nuys rental demand makes the garage-to-ADU path attractive: a permitted unit with its own entrance off the alley can be rented long-term under state ADU law. A living-space conversion — bedroom suite, office, family room — stays part of the main house and is simpler to permit and build. We scope both at the feasibility visit so the choice is made with real drawings.

Slab and foundation condition

Most Van Nuys garage slabs were poured for cars, not people: they sit low, lack moisture barriers and sometimes lack perimeter footings. We evaluate the slab and foundation first and price any underpinning, vapor barrier or raised floor as its own line, so the number is known before design.

Utilities and panel capacity

A detached garage usually has a single circuit from the house. A conversion needs a subpanel or a main-panel upgrade, new plumbing for a bathroom or kitchen, and HVAC sized for the space. Where the sewer lateral runs — and how deep — decides the cost of the plumbing run, and we locate it before estimating.

Rental use

A permitted garage-to-ADU conversion can be rented long-term under state law; most jurisdictions prohibit short-term rentals under 30 days. An unpermitted conversion cannot be legally rented and will not appraise as living space. Local rules differ, so confirm specifics with the city before you list.

• Van Nuys is within the City of Los Angeles; conversion permits are issued by LADBS — often through the Van Nuys district office itself — and every conversion requires plans, plan check and staged inspections.
• Garage-to-ADU conversions follow state ADU law. Under state law, a city cannot require you to replace the parking lost when an existing garage converts to an ADU — the California HCD ADU Handbook explains this exemption in detail. A conversion that is not an ADU can still be subject to local parking standards, so we confirm the rule for your parcel.
• Fire separation depends on distance to property lines: walls and openings close to a neighbor typically require rated assemblies and protected eaves. Title 24 energy compliance covers insulation, glazing and mechanical systems for the new habitable space.
• We prepare the drawings, submit for plan check, respond to corrections and schedule every inspection. Requirements change; we confirm them with LADBS on every project.

Timeline

Feasibility and design take a few weeks, LADBS plan check and corrections follow and vary by design and season, and construction of a conversion is typically shorter than a new detached build because the shell exists. You receive a written, phased schedule before work begins.
