Garage Conversions and ADUs in Upland, CA

Turn Your Garage Into Livable Space with a Legal ADU

With updated California housing laws, homeowners can now legally convert garages into Accessory Dwelling Units (ADUs) to provide rental income, house family members, or create private guest space. At H and H Construction, we specialize in designing and building custom, fully compliant garage conversions in Upland and surrounding cities. From planning to permits to build-out, we handle the entire process.

What Is an ADU and Why Build One?

An ADU is a self-contained living space added to a residential property. Garage conversions are one of the most cost-effective ways to create an ADU because they use the existing structure. Benefits include:
