The maximum occupancy of an ADU in Mountain View is two adults and two children.
Every ADU must have at least one off-street parking space and not take up more than one-third of the driveway space. This ensures that homeowners and guests can share the driveway and parking area so everyone can access the street.
Before building an ADU, you must obtain a building permit from the city. Getting a building permit involves submitting an application to the city development department and several required documents.
These documents include a copy of the ADU plans, a completed ADU application, and payment of the appropriate fee. This permit will authorize the construction of the unit. In addition, it provides details about the materials that must be used and the size of the unit.
If you plan to rent out your ADU, you must first obtain a rental permit from the city. This permit will include information about the rental agreement and any applicable restrictions.
Any utilities used for the ADU must be separate from those used for the existing single-family home. This includes gas, electricity, water, and sewer.
ADUs in Mountain View cannot be used as vacation rentals, a frat house, or day care.
The city has design guidelines that must be followed when constructing an ADU. These guidelines include information about the size and style of the unit.
Any landscaping or exterior features added to the ADU must maintain the view of the existing single-family home.
The city requires that the ADU have a separate exterior entrance that is not connected to the existing single-family home.
The city requires that all ADUs be taxed as separate units. This means the homeowners must pay separate property taxes for their ADU, just as they would for a separate apartment or house.
Noise from the ADU must not exceed those of the existing single-family home. This means you must keep loud music, parties, and other noisy activities to a minimum.
Subdividing an existing single-family home lot to construct an ADU is not allowed in Mountain View.
Homeowners must occupy either the existing single-family home or the ADU for at least six months out of the year to be eligible for an ADU permit.
ADUs must meet all local zoning requirements, including those related to building height, lot coverage, and setback.
All ADU structures must adhere to the city’s minimum setback requirements of 3 feet from the side and rear property lines and 5 feet from the front property line. This rule is in place to ensure that each ADU is safe from adjacent properties and to prevent any potential disputes between neighbors.
Accessory structures, such as decks or garages, must meet all local building codes and be within the maximum size requirements.
