Los Angeles-Hawthorne ADU FAQs
Frequently Asked Questions About ADUs in the Hawthorne Area
Homeowners in Hawthorne, Inglewood, Gardena, and nearby areas often ask us what types of ADUs are allowed, how long permits take, and what construction timelines look like. Below are the answers we provide during our free ADU review.
What types of ADUs can I build on my property?
In most parts of Los Angeles County, including Hawthorne, homeowners can usually build a detached ADU, an attached ADU, or a garage conversion ADU. The exact size and layout depend on your lot, existing house, and local zoning rules. During your free ADU review, we look at your property and tell you what is realistically possible.
Do you handle the plans, engineering, and permits for me?
Yes. Direct ADU is a full design-build team. We prepare the architectural plans, structural engineering, Title 24, and all required documents, and we submit them to the city on your behalf. We also respond to plan check comments and work with the city until your ADU is approved.
Can you convert my existing garage into an ADU?
In many cases, yes. Garage conversions are one of the most popular ADU types in Hawthorne and surrounding cities. We check setbacks, existing structure, and parking requirements, and then design a layout that works with your existing garage shell. We also upgrade the structure, insulation, plumbing, and electrical so it meets current code.
Do I need to move out of my home during construction?
For most ADUs, you can stay in your main home while we build. There will be noise and activity during working hours, but we coordinate access, deliveries, and inspections to minimize disruption. If any short-term access limits are needed, we discuss them with you in advance.
