Garage Conversion ADU

Convert Your Santa Clara Garage Into a Fully Permitted ADU

Many Santa Clara homeowners have an attached or detached garage that can become a fully permitted accessory dwelling unit — guest quarters, rental income, or a home for extended family. Garage conversion is one of the most cost-effective ADU types because the foundation and structure already exist. Mayer’s Construction handles the full conversion — design, permits, and build — as one integrated project with one point of contact.

🏠

Full-Service Conversion

Insulation, HVAC, plumbing, electrical, kitchen, and bath — every trade is our own in-house crew. No subcontractor coordination required from you.

📋

Permit Handling Included

State ADU law requires Santa Clara to allow garage conversions. We file all permits, manage plan check, and coordinate inspections through to certificate of occupancy.

🎨

In-House Design Included

Our designer optimizes your garage layout for livable, functional space — with material sourcing assistance for finishes, fixtures, and cabinetry.

Yes. State ADU law requires Santa Clara to allow garage-to-ADU conversions. The existing structure — foundation, walls, and roof — is already in place, which makes a garage conversion one of the most practical ADU types. Mayer’s Construction handles the full project: design, permits, all trades, and final certificate of occupancy. Call (888) 394-4041 to schedule a free feasibility visit on your Santa Clara property.
A full garage conversion ADU from Mayer’s includes: in-house design and floor plan, all permits through Santa Clara Building Division, insulation, HVAC, electrical upgrade, plumbing, kitchen and bath installation, flooring, interior finishes, and material sourcing assistance. One team, one point of contact, from the first estimate through the final inspection.
For most Santa Clara homeowners, yes. A well-built ADU typically adds 20–30% to your property’s market value. In the Bay Area, a 1-bedroom ADU rents for $2,500–$3,800 per month, which means most owners recover their full investment within 6–8 years through rental income alone — while permanently increasing what their home is worth. Mayer’s Construction handles every step in-house: design, permits, and construction under one roof, so there are no gaps, no delays from coordinating separate vendors, and no surprises on cost.
