Garage Conversion
Garage Conversion
Your garage is sitting there every day, taking up some of the most valuable square footage on your property. For most Bay Area homeowners, converting it is one of the smartest decisions they can make. More living space. More property value. A fully permitted ADU that can generate rental income or house the people you care about most.
At Mayer’s, we have been converting garages across the Bay Area Peninsula for years. We handle everything from the first design sketch to the final walkthrough.
How We Make Garage Conversions Simple
A garage conversion sounds straightforward. In reality it involves structural work, plumbing, electrical, insulation, permits and design. All of it has to be coordinated perfectly or the project falls apart.
That is exactly why having an in-house architect, engineer and designer on your team matters. Before we touch your garage, our team designs your new space and renders it in 3D so you can see exactly what it will look like. Our in-house engineer handles all structural requirements. Our designer works with you on finishes, layout and materials. And Mike and Nathan are with you throughout the entire project. We file every permit with the City of San Jose and every Bay Area municipality. We know the ADU regulations in California inside and out. Your project will not get delayed at the permit desk because of something we missed.
When the work starts, our team handles everything from foundation to finish. One company. One team. One clear plan from day one.
“We had a great experience with Mayer’s Construction. We contacted them through our neighbor’s recommendation. We wanted to remodel our kitchen and convert our garage. The project was completed in just over four weeks and the results were outstanding. We had a problem with our ceiling that Mike noticed and the crew fixed it at a reasonable price. From the beginning, we set a limit on our cost, and they were very accommodating. We are thoroughly enjoying the results and would not hesitate to hire Mayer’s for any future work.”
