Detached ADUs
Detached ADUs are standalone structures built in the backyard. These are ideal for rental units, guest houses, or private living spaces with maximum separation from the main home.
Garage Conversion ADUs
Garage conversions transform existing garage space into a fully functional living unit. This is often the fastest and most cost-effective way to build an ADU.
Attached ADUs
Attached ADUs are connected to the main home but operate as a separate living space with private entry, kitchen, bathroom, and living area.
JADUs
Junior ADUs (JADUs) are smaller units built within the existing footprint of the home. They are typically the most affordable ADU option and work well for limited space situations.
