Tiny Homes on Wheels Are an Approved ADU Option in the City of San Diego
The City of San Diego has become one of California's leaders in expanding housing options. One of the most exciting changes for homeowners is the City's adoption of regulations allowing qualifying Tiny Homes on Wheels (THOWs) to be used as Accessory Dwelling Units (ADUs). The City Council approved movable tiny homes as a distinct residential use under its ADU regulations in 2020, with later updates to the ordinance.
For homeowners looking to create housing for family members, generate rental income, or add flexible living space, a Tiny Home on Wheels can be an attractive alternative to a traditional backyard ADU.
What Is a Tiny Home on Wheels?
A Tiny Home on Wheels (THOW) is a compact home built on a trailer chassis that provides complete independent living facilities, including:
Kitchen
- Bathroom
Sleeping area
Living space
Heating and cooling
Plumbing
Electrical systems
Unlike an RV used for recreation, a THOW intended as an ADU must comply with the City's applicable requirements and permitting process.
Why Homeowners Are Choosing Tiny Homes
A luxury Tiny Home on Wheels offers many advantages:
Additional living space
- Housing for aging parents
Guest accommodations
Housing for adult children
Long-term rental opportunities where allowed
Efficient use of existing property
Many homeowners also appreciate the shorter construction timeline compared to some traditional site-built projects.
Understanding the Approval Process
Although the City allows qualifying movable tiny homes as ADUs, every property is different.
Approval depends on factors such as:
Zoning
- Lot configuration
Utility connections
Fire safety requirements
Access
Building permits
Applicable development standards
Before investing in a project, it's important to determine whether your specific property can accommodate a Tiny Home on Wheels under the City's requirements.
