Yes, building an ADU typically requires a building permit, which ensures that the structure complies with local zoning laws, building codes, and safety standards. Your contractor or designer will typically handle the permitting process, but it’s always good to double-check with your local planning department to understand the specific requirements for your area.

Frequently Asked Questions About ADUs (Accessory Dwelling Units)
What is an ADU (Accessory Dwelling Unit)?
An ADU, or Accessory Dwelling Unit, is a secondary living space on a residential property that is typically smaller than the main house. It can be attached or detached from the main dwelling and is often referred to as a “granny flat,” “in-law unit,” or “backyard cottage.” ADUs can be used for various purposes such as housing relatives, guests, or generating rental income.
What are the benefits of building an ADU?
Additional Living Space: Perfect for growing families, elderly relatives, or guests.
Rental Income: Renting out an ADU can be a source of passive income.
Property Value Increase: Adding an ADU can increase the overall value of your property.
Flexible Use: ADUs can serve as guest houses, home offices, studios, or rental units.
How much does it cost to build an ADU?
The cost of building an ADU can vary greatly depending on factors like size, design, materials, and location. On average, homeowners can expect to pay between $80,000 to $250,000 for an ADU project. This price includes design, construction, and permitting costs. Keep in mind that costs may also differ based on whether the ADU is detached or attached.
What is the size limit for an ADU?
The maximum allowable size for an ADU depends on local zoning laws. In many areas, the typical size limits are between 600 to 1,200 square feet for detached units. However, some municipalities may have different regulations, so it’s important to check with your local city or county office for exact guidelines
Can I rent out my ADU?
Yes, in most areas, you are allowed to rent out your ADU as a long-term or short-term rental, such as through platforms like Airbnb. However, local zoning laws and building codes may have specific requirements for renting out an ADU, including rental registration and permit applications. It’s essential to confirm the rental regulations with your local government.
Do I need a permit to build an ADU?
What are the zoning requirements for an ADU?
Zoning requirements for ADUs vary by location. In general, ADUs are allowed in residential zones, but there may be restrictions on the size, height, setback, and parking requirements. Some areas may have specific conditions for both attached and detached units, so it’s essential to consult your local zoning office before beginning the design and construction of your ADU.
Can I build an ADU in my garage or convert an existing space?
Yes! One of the most popular types of ADUs is a garage conversion, where an existing garage or storage space is transformed into a fully functional living area. This is often more affordable and quicker than building a detached ADU. Depending on your garage’s layout and the local regulations, you may be able to convert it into a living space without needing to build an entirely new structure.
What utilities are needed for an ADU?
ADUs need basic utilities such as water, electricity, and sewage. Depending on the type of ADU and your location, you may need to extend existing utility lines from your main home to the new structure, or in some cases, install separate utilities. Your contractor will help coordinate with local utility providers to ensure proper connections.
How long does it take to build an ADU?
The timeline for building an ADU can range from 4 to 12 months, depending on factors like design complexity, permitting, and construction. Simpler projects, such as converting a garage or using an existing structure, may take less time. Custom-built, detached ADUs may take longer due to the need for more extensive planning, permits, and construction.
Do ADUs require separate entrances?
Yes, most ADUs are required to have a separate entrance to ensure privacy for both the primary house and the ADU. This is especially important if you plan to rent out the unit. Your local jurisdiction will have specific rules regarding entrance locations, design, and accessibility.
Can I add an ADU to my existing home even if I have a small lot?
Many local governments are making it easier for homeowners to build ADUs on smaller lots, especially in urban areas. If you have a small lot, you may still be able to build a small ADU, but there may be restrictions on its size, height, or placement. Some jurisdictions offer exceptions or streamlined processes to encourage ADU development on smaller properties. Be sure to check with your local planning department.
