Detached ADUs

A detached ADU is a standalone unit built separately from your main house, often located in your backyard. This option provides maximum privacy and independence while adding significant value to your property. It’s an ideal solution for homeowners looking to create a rental unit for additional income, a guest house for visiting family and friends, or a multigenerational living space to keep loved ones close while maintaining privacy. Detached ADUs are also a great option for those who need a dedicated home office or studio space, allowing for a productive environment away from the main house.

Attached ADUs

An attached ADU is built as an extension of your existing home and shares at least one wall with the main structure. This option allows for a seamless integration with your home’s design while still providing a separate and private living area. Attached ADUs work well for in-law suites, additional bedrooms, or even home offices that offer a quiet and functional workspace. Since they are connected to the main home, they often require fewer utility upgrades compared to a detached ADU, making them a more budget-friendly option.

Junior ADUs (JADUs)

A junior ADU, or JADU, is a compact unit that is typically created within the existing footprint of the main house, often by converting part of a larger bedroom, an unused living area, or a garage. These units are limited to 500 square feet but can include a kitchenette and a separate entrance. JADUs are a great option for homeowners looking for an affordable way to add extra living space for aging parents, young adults, or a short-term rental opportunity.

Garage Conversions

A garage conversion transforms an existing garage into a fully functional living space. This is one of the most cost-effective ways to build an ADU, as it utilizes an existing structure while significantly increasing the home’s livable square footage. Garage conversions are a great choice for homeowners who want to create a rental unit, a private guest suite, or an extra bedroom without expanding their home’s footprint. Since the structure is already in place, these projects often have a faster approval and construction timeline.
