Beautiful, small, prefabricated backyard homes are now all electric. These Accessory Dwelling Units (ADUs) offer the benefit of zero emissions, reduced energy costs, increased safety, and enhanced personal health. There is no need to install a natural gas line, saving occupants from harmful pollutants! Some ADUs are designed to include high-rated insulation, solar panels, heat pump water heaters and HVAC, induction cooktops, and Energy Star appliances. ADUs are usually fully constructed offsite, so installation at the property can take from as little as two to twelve weeks.

Homeowners may supplement income by renting their ADU(s) to singles, couples, or small families. ADUs often increase property values. The fair market value can increase by 1.5 – 2 times the cost of construction. ADUs can also provide a housing solution for live-in nannies, college-aged children, or elderly parents. The construction of ADUs helps cities reach their housing goals, too, especially for low- and moderate-income renters.
While custom ADUs can be designed in a myriad of styles, prefabricated ADUs typically feature sleek, simple lines, lots of natural light, and the use of natural materials such as wood and stone. They are enhanced by neutral colors, a lack of clutter, and compact functionality. A thoughtful floor plan, high quality construction and installation, and artful landscaping can add beauty to your property.

State and local laws have been crafted to streamline the ADU building process. Usually, only a building permit is needed, requiring no public notice, no hearing, and no neighborhood input. Once the ADU plan is submitted, the turnaround time for the permit is about three weeks. The state has mandated limits on the review and response times so homeowners can now have a smoother, quicker approval process. Most builders provide all-in-one service; they obtain the permit, clear the land, prepare the plumbing and electrical transitions, install the ADU, and landscape the site.

ADUs are tailored to the lot size and can be selected by architectural style and budget. They can stand separate from the main house, be constructed as an attached addition to the main house, or even be constructed as a remodel of an existing portion of the main house. Some of the ADU companies working in the Bay Area include Samara, Villa Homes, Adore Homes, Eano, Blu Homes, Digz2Go, Adobu, Bay Modular, Hybrid Core Homes, Mighty Buildings, Avava, Habitat Homes, Shilo, Veev, and Modern Empathy.
