Frequently Asked Questions

An Accessory Dwelling Unit (ADU) is a secondary housing unit located on the same property as a primary residence. It can be attached or detached and serves as an independent living space with its own entrance, kitchen, and bathroom.

ADUs offer increased living space, provide rental income opportunities, create space for family members, and can add value to a property while making efficient use of available land.

ADUs come in several types: detached units (standalone buildings), attached units (extensions or conversions of existing spaces), and garage conversions. Each option provides different layout and design possibilities.

Yes, zoning regulations vary by location. Local codes determine where ADUs can be built, their size, setbacks, and parking requirements. It’s essential to check with your city or county for specific rules and approval processes.

In many areas, you can build an ADU in your backyard, as long as you comply with local zoning laws, setback requirements, and other regulations regarding size and access. A detached ADU is often ideal for backyard construction.

Costs vary based on size, materials, and location. Key factors include the need for new plumbing or electrical work, foundation requirements, and whether the unit is a new construction or a conversion of existing space.

The timeline for building an ADU typically ranges from a few months to a year, depending on complexity, permitting, and construction phases. Detached ADUs may take longer due to the need for additional infrastructure like utility connections.

Financing options include home equity loans, personal loans, construction loans, or using savings. Some areas also offer incentives or financing programs to encourage ADU development for affordable housing.

Yes, ADUs can be rented out as long as local zoning and rental regulations allow it. Many homeowners build ADUs specifically for rental purposes, providing a steady stream of passive income.

Building an ADU can increase your property’s market value, as it adds living space and potential rental income. However, the value increase depends on the unit’s size, quality, and how it fits into the neighborhood’s housing market.
