Common Questions

ADU & Garage Conversion FAQ

Do I need a permit for a garage conversion or ADU?
Yes. Yes. All ADU conversions and garage conversions in Los Angeles County require building permits and inspections. We handle the entire permit process for you.
How long does a garage conversion take?
Garage conversions typically take 3 to 5 months from permit approval to completion. New-build ADUs take longer, usually 5 to 8 months.
Can my parents or adult children live in the ADU?
Absolutely. About one-third of Latino families in the U.S. live in multigenerational households. An ADU gives aging parents or adult children their own private living space while keeping the family under one roof. We see this every day in Southeast LA.
Can my ADU generate retirement income?
Yes. A garage conversion ADU in Los Angeles can generate $1,500 to $2,500 per month in rental income. Many homeowners approaching retirement are building ADUs to create a steady second income. Some even move into the ADU and rent the main house for even more.
What is SB 9 and can I use it with my ADU?
California Senate Bill 9 (the HOME Act) allows homeowners to build up to two primary units on a single-family lot, or split their lot into two parcels with up to four units total. This is separate from ADU law. Depending on your property and your city's rules, you may be able to combine an ADU with SB 9 units for even more options. Some homeowners use this to create housing for multiple generations of their family or to maximize rental income. We can walk through your options during a free consultation and help you understand what's possible on your specific lot.
What cities do you serve?
We serve homeowners in Downey, Lakewood, Cerritos, Whittier, Pico Rivera, Norwalk, South Gate, Bell Gardens, Huntington Park, and across Southeast Los Angeles.
