Installation and Construction Requirements

You should understand the specific regulations and requirements that govern the construction process of Bonita granny flats. Here are some regulations you need to be aware of:

Zoning and Permits

Your property must be zoned for residential use, and the granny flat is considered an Accessory Dwelling Unit (ADU) or Junior Accessory Dwelling Unit (JADU) under California state law.

Setback Requirements

For attached Bonita granny flats, there’s typically a minimum setback of 4 feet from the side and rear property lines. Detached granny flats generally require setbacks of 5 feet from side and rear property lines.

Maximum Size and Height

Attached ADUs can be up to 50% of the existing primary dwelling’s living area or 1,200 square feet, whichever is smaller. Detached ADUs are limited to 1,200 square feet.

The maximum height of a detached ADU, on the other hand, is 16 feet while that of an attached ADU is limited to the height of the primary dwelling.

Utilities and Connections

Separate utility connections for the granny flat are not required. ADUs can share utility connections with the primary residence. Adequate utility connections for water, sewer, and electricity must be provided in compliance with local standards.

Access and Parking

If the Bonita granny flat is located within half a mile of public transit, no additional parking is required. If not within half a mile of public transit, one off-street parking space per ADU is required, either within a garage, carport, or on the driveway.

Granny Flats Boost You Home’s Value & ROI

The ROI of different types of Bonita granny flats varies based on several factors. Here’s how different Bonita granny flats can impact your home’s value:

Rental Income Potential

Many property owners in California have reported significant rental income from their ADUs. The specific ROI can vary, but it’s not uncommon for well-designed and strategically located ADUs to generate a positive cash flow.

Property Value Appreciation

ADUs have the potential to enhance the overall value of the property. Adding a well-designed ADU can attract more potential buyers or tenants, leading to increased demand and potentially higher property values.

Regulatory Changes

California has made efforts to streamline the ADU permitting process and ease regulatory restrictions. These changes have made it more feasible for property owners to construct and rent out ADUs, positively impacting their ROI.

Flexible Use

ADUs offer flexibility for property owners. They can be used to accommodate family members, generate rental income, or even provide space for a home office or personal studio.
