Garage Conversions in Simi Valley

Simi Valley homeowners call AAA All Star Construction when they want the job done right. A garage conversion is often the fastest and most affordable way to add a legal living unit in Simi Valley. The walls, slab and roof are already there; we bring the space up to code for habitation and finish it like the rest of your home.

Simi Valley is about 24 miles west of our North Hollywood office, so our Southern California crews are on site quickly for estimates, inspections and the day-to-day work.

What's included

• Assessment of the existing slab, framing and roof
• Insulation, drywall and Title 24 energy upgrades
• Replacing the garage door with a code-compliant wall and windows
• New plumbing for a kitchen and bathroom
• Electrical subpanel, lighting and outlets
• Flooring, paint and finish carpentry

Building in Simi Valley

Hot summers and seasonal Santa Ana winds in Simi Valley affect roofing, exterior finishes and landscaping choices. We use wind-rated installation methods and heat-tolerant materials suited to inland Southern California.

Building permits for Simi Valley projects are issued by the City of Simi Valley. Converting an existing garage into an ADU is covered by the state ADU laws, and replacement parking is generally not required when a garage is converted. We confirm the details with the Simi Valley building department.

What affects the price

• Condition of the existing slab and whether it needs a vapor barrier or leveling
• Adding a kitchen or bathroom (sewer and water connection)
• Electrical service capacity
• Windows, egress and ceiling height
• Finish materials

Simi Valley Garage Conversions FAQ

Is a garage conversion cheaper than a new ADU?

Usually, because the foundation, walls and roof already exist. The final price depends on the condition of the structure and whether you add a kitchen and bathroom.

Do I have to replace the parking I lose?

Under California ADU law, replacement parking is generally not required when a garage is converted to an ADU. We verify this for your specific Simi Valley property.

How long does a garage conversion take?

Construction typically runs 8 to 14 weeks after permits are issued, depending on scope.

Do you serve all of Simi Valley?

Yes. We work throughout Simi Valley and the surrounding Ventura County communities from our North Hollywood office. Call 844-975-5512 to schedule a free estimate.
