San Diego has become one of the most active markets for Accessory Dwelling Units (ADUs) in the entire state of California. Thanks to its high property values, year-round desirable climate, and a persistent housing shortage, homeowners across neighborhoods like North Park, Ocean Beach, and Chula Vista are turning to ADU contractors in San Diego to maximize their property's potential. The city has embraced state-level ADU reform laws, making it easier than ever to build a secondary unit on your property.
Working with an experienced San Diego ADU contractor is essential because local regulations can be complex. San Diego follows California state law, which allows ADUs on most single-family and multi-family residential lots. Key rules include:
San Diego has streamlined its ADU permitting process through the Development Services Department (DSD). The city offers pre-approved ADU plans, which can significantly reduce approval timelines. A qualified ADU builder in San Diego will handle the permit application, architectural drawings, structural engineering, and coordination with city inspectors. Typical permit approval times in San Diego range from a few weeks for pre-approved plans to several months for custom designs.
Choosing the right contractor is critical to a successful ADU project. Reputable ADU contractors in San Diego will offer end-to-end services, including design, permitting, construction, and final inspection. When evaluating contractors, look for:
The cost to build an ADU in San Diego typically ranges from $150,000 to $350,000 or more, depending on size, type, and finishes. However, given San Diego's strong rental market — with average rents among the highest in California — homeowners can often see a strong return on investment. A well-built ADU can generate $1,500 to $3,000+ per month in rental income, making it a smart long-term investment in one of America's most competitive real estate markets.
