Welcome to our guide on accessory dwelling units (ADU), also known as secondary suites. ADUs are separate living units located on the same property as a single-family home. They offer a range of benefits, from providing flexible living space to potential financial advantages.
However, building and designing an ADU involves navigating specific regulations and permit requirements. Let’s explore how ADUs work and uncover the key elements you need to know.
What is an ADU?
An Accessory Dwelling Unit (ADU) is a smaller living unit that is located on the same property as a single-family home. It provides a separate and self-contained space that can be utilized for a variety of purposes. ADUs are becoming increasingly popular due to their versatility and potential benefits.
ADUs can take different forms, including:
- Detached structures
- Converted portions of existing homes
- Additions to existing homes
ADUs are subject to specific regulations and zoning laws imposed by local authorities. These regulations dictate various aspects of ADU construction, such as size, utility connections, and occupancy. The specific regulations may vary from city to city or municipality to municipality.
Creating an ADU requires adhering to local zoning regulations to ensure compliance with guidelines. These regulations are in place to maintain the harmony of the neighborhood, protect the interests of the community, and guarantee safety.
ADU zoning refers to the specific areas designated by local authorities where ADUs can be built. Zoning regulations outline the specific requirements, restrictions, and allowances for ADUs in each designated area.
ADU Zoning and Regulations
ADU zoning and regulations are important for deciding where and how ADUs can be built. Zoning laws determine factors like lot size, setbacks, and accessibility rules to maintain neighborhood character. Regulations cover aspects like occupancy, parking, and utilities to ensure ADUs are safe and meet standards.
Understanding ADU zoning is crucial for building one. Compliance avoids legal problems and ensures the ADU meets standards.
Below is a table highlighting some common ADU regulations:
| Regulation | Description |
|---|---|
| Size | ADUs must meet specific size requirements, which vary depending on the location. |
| Occupancy | Regulations often limit the number of people who can live in an ADU. |
| Utility Connections | ADUs must have proper connections to utilities such as electricity, water, and sewage. |
| Design | ADUs must adhere to certain design standards, ensuring harmony with the existing neighborhood. |
Types of ADUs
ADUs, or accessory dwelling units, can take various forms to suit different property layouts and homeowner preferences. Let’s explore the different types of ADUs:
Detached ADU
A detached ADU, also known as a backyard cottage or laneway house, is a separate structure located on the property but not physically attached to the main house. It offers privacy and independence, making it an attractive option for homeowners who desire a separate living space for themselves or as a rental unit.
Garage Conversion ADU
A garage conversion ADU involves converting an existing garage into a living space. This type of ADU is ideal for homeowners who have an underutilized garage and want to transform it into a functional living area. Garage conversion ADUs save space and can be cost-effective compared to building a separate structure.
Attached ADU
An attached ADU is an additional living space that is physically connected to the main house. It can be positioned above a garage, beside a workshop, or as an extension of the existing dwelling. Attached ADUs provide convenience and easy access to the main house while still offering a separate living area.
Basement Conversion ADU
A basement conversion ADU involves transforming an unfinished or underutilized basement into a livable space. This type of ADU maximizes the existing footprint of the property and can offer additional square footage without the need for extensive construction. Basement conversion ADUs are commonly used as rental units or for accommodating extended family members.
Internal ADU
An internal ADU refers to an additional living space that is integrated within the existing structure of the main house. This may include converting underutilized rooms, adding an independent suite within the house, or repurposing space such as an attic or a wing of the house. Internal ADUs provide flexibility and can be seamlessly incorporated into the overall layout of the home.
Each type of ADU has its own unique characteristics and considerations when it comes to design, construction, and zoning regulations. Homeowners should carefully evaluate their property and requirements to choose the ADU type that best suits their needs.

Here are some key points to keep in mind regarding ADU zoning and regulations:
- Zoning laws specify where ADUs are allowed to be built within a particular jurisdiction.
- Minimum lot size requirements may determine whether your property is eligible for an ADU.
- Setbacks refer to the minimum distance required between the ADU and the property boundaries or other structures.
- Accessory structure restrictions may limit the size and design of ADUs to preserve the aesthetics of the neighborhood.
- ADU regulations address occupancy limits, which dictate the number of people allowed to reside in the ADU.
- Parking requirements may stipulate the minimum number of parking spaces needed for ADU residents.
- Utility connections, such as water, electricity, and sewage, must meet the requirements set by local regulations.
Example of ADU Zoning and Regulations
In Los Angeles, ADUs are allowed in various zoning districts like R1, R2, and RD, but they have specific rules. For instance, they must be on the same lot as the main home and can’t be larger than 1,200 square feet. Also, they need to have setbacks of at least 5 feet from side and rear property lines.
Remember, ADU rules can differ by area, so it’s smart to check with your local planning department or an ADU builder to know the exact requirements where you live.
