About Our Team
Professional ADU Contractor in Los Angeles
If you need a professional ADU contractor in Los Angeles, our team manages the entire process from architectural design to final permitting and construction. The City of Los Angeles has simplified its ADU regulations to help homeowners build accessory dwelling units, eliminating previous limitations such as owner-occupancy rules, minimum lot sizes, and restrictive setbacks. Most single-family properties under the jurisdiction of the Los Angeles Department of Building and Safety can now add at least one detached ADU. Some lots are eligible for both an ADU and a Junior ADU. Working with our experienced team ensures your project complies with all local guidelines, from initial planning through the final ADU contraction in Los Angeles.
Building an ADU is an excellent way to secure rental income or provide housing for family. High rental demand across Los Angeles makes this a valuable investment. Our team handles every phase of design and ADU construction in Los Angeles, so you can build with confidence.
