Room Conversion ADU

Unlock Hidden Space: Create a Room Conversion ADU in Southern California!

Do you have a spare room or unused space in your Southern California home? You can unlock its potential and create a valuable Accessory Dwelling Unit (ADU) with a room conversion! At pacific sands, we specialize in transforming underutilized rooms into functional and stylish ADUs.

What is a Room Conversion ADU?


Room conversion ADUs utilize existing space within your home. This could be a large bedroom, a basement area, or even a sunroom. By adding a separate entrance, kitchenette, and bathroom, you can create a complete living space for tenants or guests.

Benefits of a Room Conversion ADU:

  • Maximize your existing space: Put that spare room to good use and generate income.


  • Boost your property value: A well-designed ADU can significantly increase your home's worth.


  • Offer flexible living options: Create a dedicated guest suite, in-law unit, or income-generating rental.



  • Enjoy a faster construction process: Room conversions often take less time to complete than detached ADUs.
