The company specializes in the design, planning, and construction of accessory dwelling units, helping property owners navigate the process from initial concept through to a completed build. Their team includes certified contractors, architects, and other building professionals, along with qualified tradespeople such as electricians and plumbers.
Accessory dwelling units — also referred to as granny flats, backyard cottages, secondary units, or in-law suites — are smaller, self-contained dwellings that share a lot with a primary residence. They are a legal housing option in San Diego County and have grown in popularity as a way to add livable space, accommodate family members, or generate rental income. An ADU cannot be sold separately from the main property, but it can contribute to the overall value of the lot.

The maximum allowable size for an ADU in San Diego is 1,200 square feet, and county regulations allow up to two ADUs on a single residential lot, provided all local zoning requirements are met.
