Unlocking Extra Living Space: The Power of ADUs
An Accessory Dwelling Unit (ADU) is a separate living space built on the same lot as your primary home. Whether detached, attached, or converted from an existing structure, ADUs are one of the most effective ways to expand your home's footprint — legally and permanently. San Diego homeowners can expand their current home footprint by up to 50% with an attached ADU, or build a detached ADU up to 1,200 sq. ft. Pre-approved floor plans and fully customizable designs are available.
Why Add an ADU?
The Many Benefits of Adding an ADU to Your Property
An ADU is one of the highest-return improvements a San Diego homeowner can make. From generating rental income to supporting family members, here is why homeowners choose to build.
1- Multi-Generational Living
Keep aging parents or adult children close while giving everyone their own private space and independence.
2- Rental Income
Generate consistent monthly rental income by renting your ADU on a long-term or short-term basis, offsetting your mortgage or building wealth.
3- Increased Property Value
Adding a permitted ADU significantly increases your home's market value and appeal to future buyers looking for income potential.
4- Potential for Work or Hobby Space
Use your ADU as a dedicated home office, art studio, gym, or workshop, separated from the main living area for focus and quiet.
5- A Sustainable Choice
ADUs make efficient use of existing land and infrastructure, reducing urban sprawl while adding density responsibly in established San Diego neighborhoods.
