17.78.010 Findings.

  1. The adoption of an accessory dwelling unit ordinance which permits accessory dwelling units by ministerial review in R-1, and R-2 including R-1/PD (single-family residential/planned development) districts developed with detached single-family

dwellings is consistent with the goals and policies of the Foster City general plan in that accessory dwelling units would help meet the need for affordable housing. Furthermore, construction of accessory dwelling units would not be as costly as new construction, because there are no additional land costs, infrastructure costs are reduced, and an accessory dwelling unit can be added at the cost of an addition to, or remodeling of, the main single-family dwelling.

  1. The accessory dwelling unit ordinance as proposed would not be detrimental to the health, safety and welfare of surrounding residents, the character of existing neighborhoods, or the community as a whole, in that the ministerial permit process provides the city with adequate control over specific requirements such as on-site parking, compliance with zoning requirements (lot coverage, setback, etc.) and limitations on unit size.
  2. Due to the small minimum lot sizes allowable and in order to prevent the overdevelopment of single-family and two-family lots, maintain sufficient separation between dwelling units for protection of privacy and provision of adequate light and ventilation, and preserve the residential character of properties within the R-1, R-2, and R-1/PD zones, the maximum size of any accessory dwelling unit is established as 640 square feet.

17.78.020 Purpose.

The purpose of this chapter is to develop accessory dwelling units through ministerial permit procedures which set forth conditions that mitigate neighborhood and environmental impacts.

17.78.030 Application.

The provisions of this chapter shall apply in R-1, R-2 and R-1/PD districts. Accessory dwelling units are not permitted in any other district. Except when sited within the envelope of an existing permitted and legally-constructed primary residence, no accessory dwelling unit may be sited on a lot less than 5,000 square feet in size in the R-1 or R-2 districts or on a lot less than the minimum lot size allowable in the R-1/PD district.

17.78.040 Definitions.

  1. “Accessory dwelling unit” means an attached or a detached residential dwelling unit which provides complete independent living facilities for one or more persons.
