ADU Modular Homes

What is an Accessory Dwelling Unit?

ADUs have many synonyms and come in a variety of shapes and forms, ranging from basement built-outs to stand-alone structures. They can be attached to or detached from the primary home or located above a garage. Basically, an accessory unit is a secondary and smaller structure set on a large enough property that already has a primary residential home on it. Many ADUs are connected to the power and water utilities of the primary home but can have their own as well.

Does an ADU add value to your property?

Yes, an ADU adds value to a property. The next logical question is, “How much value does an ADU add?”. Unfortunately, it’s impossible to provide an universal answer to this question. The contributory value of an ADU is at times difficult to measure. But, professional appraisers will look for recent sales comparisons on which to base their appraisals. Their appraisal represents their professional opinion of value of the property based on the sales comparison data that is available to them at the time of their appraisal.

Do I need a permit to build an ADU?

Yes, you always need a permit from your local jurisdiction to build habitable living space on your property. If the space is non-habitable, and is under 200 sq ft, then sometimes you do not need a permit. However, this exception varies from one municipality to another. But, in the case of building habitable living space, such as an ADU, you (or your builder) are always required to obtain a building permit and to adhere to the local building code.

Must an ADU have a kitchen & bathroom?

Yes, ADUs must have a kitchen and a bathroom. In fact, they are two of the defining features of an ADU that differentiates it from other habitable living spaces such as an office or guest space. An ADU must also have a separate and private entrance. The ADU may, but is not required to, include access to the primary dwelling. However, it is not considered an ADU if it can only be accessed through the primary dwelling or the area is open to the primary dwelling with no expectation of privacy.
