Building an ADU in Bellflower
Bellflower grew rapidly in the postwar years, and its neighborhoods are filled with single-story ranch homes on comfortable rectangular lots. Many blocks have alleys or long driveways leading to detached garages behind the house, and backyards tend to be open, flat, and large enough to offer genuine choices about where a new structure could go.
That gives Bellflower homeowners two strong ADU paths. Detached garages — especially those on alley-served blocks — convert cleanly into rental-ready units with their own access, and open backyards often accommodate a detached cottage or in-law suite. We look at access, privacy between the two homes, and utility routes to recommend the option that delivers the most value for the property. Neighborhoods toward the Lakewood border share the same postwar ranch pattern, with rear garages that convert cleanly.

Common questions about ADU costs, permits, and timelines.
213-816-6012How much does an ADU cost in Los Angeles?+
ADU construction in Los Angeles ranges from $90,000 for a basic garage conversion to $450,000+ for a custom-built detached 1,200 sq ft ADU. Most of our clients invest between $180,000 and $300,000 for a turnkey project including permits, design, and finishes.
How long does it take to build an ADU?+
A typical detached ADU takes 6–9 months from permit submittal to final inspection. Garage conversions are faster — usually 3–4 months. Prefab ADUs can be installed in as little as 8 weeks once site prep and permits are complete.
Do I need a permit to build an ADU in Los Angeles?+
Yes. All ADUs require a permit from LADBS or your local city building department. State law makes the approval process ministerial — meaning if your plans meet code, the city must approve them. We handle the entire permit process for you.
Can I rent out my ADU?+
Yes. California state law allows you to rent your ADU long-term (30+ days). Short-term rentals like Airbnb depend on your local city ordinance — Los Angeles has additional restrictions.
Will an ADU increase my property taxes?+
Only the newly built ADU is reassessed. Your existing home keeps its current Prop 13 tax basis. Most homeowners see a tax increase of $1,500–$3,500 per year, depending on the ADU's assessed value.
What's the difference between an ADU and a Junior ADU (JADU)?+
A JADU is a unit up to 500 sq ft created within the walls of your existing home, with its own entrance and kitchenette. ADUs can be detached, attached, or converted and up to 1,200 sq ft.
My Bellflower garage sits on an alley. Does that help an ADU project?+
It does. Alley access means the converted unit can have its own entrance and approach, separate from the main house — a real advantage for rentals and multigenerational living alike.
Should I convert my garage or build a new detached unit in Bellflower?+
If your garage is structurally sound and well placed, a conversion is usually faster and less expensive. If you want a larger unit, higher ceilings, or a better position in the yard, new detached construction may be worth the extra investment. We price both so you can compare.
