  • A detached ADU, which is a completely separate building from the main house.

You can either construct a new building for your ADU or convert an existing structure into one. The advantage of conversion is that it typically bypasses setback and height restrictions, and you can even expand the space for a larger ADU. However, converting older structures may lead to unforeseen issues that could increase the overall cost of the project.

ADU setbacks from the property lines and other buildings

What are the required setbacks for an ADU in Bellflower?

ADUs need to be set back at least 4 feet from the side and rear property lines. If a property line is in the middle of a public right-of-way, setbacks are measured from the edge of that right-of-way.

This could involve a connection fee or capacity charge based on factors like size or drainage fixture unit value.

The parking requirements for ADU

What is the parking requirement for an ADU in Bellflower?

In Bellflower, each ADU requires one parking space. However, there are exceptions. ADUs within a half-mile of public transit, in significant architectural or historical districts, or part of a primary dwelling or accessory structure do not need parking. Additionally, if the ADU is in an area without parking permits for occupants or within one block of a carshare vehicle, the parking rule doesn’t apply.

Where can I have a parking space on my property?

Parking for an ADU can be set up as tandem parking on a driveway or within setback areas. If a garage or carport is taken down or converted into an ADU, no replacement parking is needed.

How to get permits for your ADU

How long does it take to get an ADU permit in Bellflower?

The permitting process generally takes about 3.5 to 4 months. After preparing the permit drawings, you or your architect should submit them for a Plan Check. It's recommended to schedule a pre-check meeting with the planner to go over your application before submission.

Once submitted and the fees are paid, the city has 60 days to determine if your application is complete. If they don’t respond within that time frame, the permit is automatically approved. If corrections are needed, your designer will need to make the necessary changes and resubmit. Your application should provide adequate details to ensure compliance with ADU requirements. Missing information won’t lead to an automatic rejection. The cost for Plan Check services for ADUs in Bellflower is approximately $2,780.

Does Bellflower require in-person submission of plans for an ADU?

Yes, in Bellflower, you need to submit ADU plans in person to the city's Planning Division to ensure they meet local zoning regulations and guidelines.

No, you don’t need coastal development permits in Bellflower.

When do you need a licensed professional to design an ADU in Bellflower?

Cost, financing and market value of ADUs

Is it profitable to build an ADU in Bellflower?

Profitability can also be assessed by considering potential rental income or the benefits of having family members live on the same property.

Can you sell an ADU in Bellflower?

Yes, you can sell an ADU in Bellflower if certain conditions are met. The city has to have a local ordinance that allows ADU sales and explains the rules. If a qualified nonprofit built the ADU, you can sell it separately. You can also use a tenancy in common agreement to divide the property based on specific guidelines. Additionally, the city may let you sell the ADU and the main home as separate condominiums, provided you follow all relevant rules.

Are ADUs rent-controlled in Bellflower?

No, ADUs in Bellflower are not subject to rent control ordinances. Due to their status as newly constructed units, they are exempt from such regulations, unlike older properties typically aged 15 years or more, which are impacted by rent control. Consequently, legislation like AB 1482, addressing rent control, does not apply to ADUs in Bellflower.

How do I get money to build an ADU in Bellflower?

In Bellflower, homeowners have various options to secure funding for constructing an ADU. One avenue is through participation in the CalHFA ADU Grant Program, accessible within the city.
