The Bay Area is experiencing a boom in the construction of Accessory Dwelling Units (ADUs), and it’s not hard to see why. Here’s a closer look at why more people are building ADUs in the Golden State. Traditional ADUs take cues from classic architectural styles, such as Colonial, Victorian, or Georgian. These units often include decorative elements like cornices, columns, and brick or stone facades. Interiors might feature crown molding, wainscoting, and traditional cabinetry, offering a timeless and elegant living space.

Who is buying ADUs?

We help you prepare for the local process and avoid common “gotchas” that cause delays. We start with your “why” (rental, family suite, office, resale) and your site constraints (access, slope, utilities, setbacks). A customized guide walking homeowners through every step of the ADU process in your community.

This depends on what your local zoning code says is permissible. In other cases, an ADU may not be allowed, but alternatives such as a guest house or a detached office or bedroom with a bathroom may be allowed. Use fiberglass or acrylic tub/shower surrounds—one-piece units eliminate leak-prone seams. Wall-mounted vanities make small bathrooms feel more spacious.

Construction Pros Who Understand Rental Properties

Some cities are jumping on board the ADU train by improving their ordinances and development regulations to make ADUs easier to build. Frankly, there’s an underlying sentiment of resistance to change, and it’s politically challenging to pass good ADU regulations. Seattle provides the nation with a cautionary tale of the fear that surrounds the idea of ADUs amongst some neighborhood associations. Seattle’s city commissioner’s valiant efforts to improve ADU regulations were hung up in a legal battle and were postponed by a year as a result. ADUs are defined by the fact that they’re a type of housing unit—NOT a standardized structural form.

If the space is non-habitable, and is under 200 sq ft, then sometimes you do not need a permit. But, in the case of building habitable living space, you’re always required to obtain a building permit. An accessory dwelling unit, usually just called an ADU, is a secondary housing unit on a single-family residential lot.
