How much does an ADU cost in Los Angeles?

Cost depends on whether it is a garage conversion or new construction, the size of the unit, utility connections and the finishes. We don't quote numbers before seeing the project: after reviewing the space we give you a free, written, itemized estimate.

How long does it take to build an ADU in LA?

From permit submission to final inspection, most ADU projects take 6–12 months. Garage conversions can be faster, sometimes completed in 4–6 months.

Do I need permits to convert my garage to living space?

Yes — all garage conversions and ADUs require permits. EC Construction Group handles all permits, engineering, and city inspections as part of our turnkey service.

Can I rent out my ADU in Los Angeles?

Yes — ADUs and garage conversions can be legally rented as separate dwelling units in Los Angeles under California ADU law. They are a popular source of rental income for homeowners.

What is the difference between an ADU and a garage conversion?

An ADU can be a detached, attached, or converted living space, while a garage conversion transforms an existing garage into a legal dwelling unit. Both options can add living space and increase property value.

What size ADU can I build on my property?

The allowable ADU size depends on your lot, zoning regulations, and local city requirements. Our team evaluates your property and identifies the maximum allowable size for your project.

Do you handle ADU design, engineering, and permits?

Yes. EC Construction Group manages the entire process, including design, engineering, permit applications, city approvals, and construction.

Will an ADU increase my property value?

In many cases, an ADU can significantly increase property value while also creating rental income opportunities and additional living space for family members.

Can family members live in an ADU?

Yes. Many homeowners build ADUs to accommodate parents, adult children, guests, or multi-generational living arrangements while maintaining privacy.

Are you a licensed contractor?

Yes. EC Construction Group is a California licensed contractor (CSLB #1132619) for ADU construction and garage conversion projects throughout Los Angeles and the San Francisco Bay Area. You can check the license status, bond and workers' compensation details on the CSLB website, cslb.ca.gov.
