Mountain View lists a typical permit time of 3 to 8 months for single-family additions, depending on scope. An addition that needs a floor area ratio exception or variance, or a conforming addition to a nonconforming home, may require a Planning Division permit. We prepare the plan set and the structural and energy calculations, and we secure the necessary permits.
