About Us
A1 ADU Contractor is a licensed California general contractor focused on turning underused garages into legal, livable space across Los Angeles County, including Sherman Oaks, Granada Hills, Encino, Burbank, and North Hollywood. Most of the work centers on converting existing garage footprints into ADUs, whether that's a rental unit, an in-law suite, a home office, or a studio apartment.
The team handles the project end to end: design, permitting, and construction, so homeowners aren't stuck coordinating separate architects, permit expeditors, and crews. Beyond standard garage-to-ADU conversions, the company also builds custom ground-up ADUs, prefab installations, and multi-dwelling units for property owners looking to add rental income or extra living space.
Client reviews point to a consistent focus on smooth permitting and inspections, flat-rate or transparent pricing, and builds that pass city inspection without repeated delays. That matters in a process where permitting holdups and surprise costs are often the biggest headache for homeowners taking on an ADU project.
