Microunit buildings.

The Planning and Zoning Law authorizes the legislative body of any county or city to adopt ordinances regulating zoning within its jurisdiction, as specified. This bill would require a city or county with a population of more than 400,000 people to permit the building of microunit buildings, as defined, in any zone where multifamily residential buildings are permitted. The bill would require that microunit buildings be permitted on the same basis as multifamily dwelling units. The bill would set minimum standards for the construction of microunit buildings, including floor-space ratios and setback requirements. The bill would require that specified percentages of microunit buildings be set aside for affordable housing, as specified. The bill would define terms for the purpose of these provisions. Because this bill would impose additional zoning requirements on local governments, it would impose a state-mandated local program. The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement. This bill would provide that, if the Commission on State Mandates determines that the bill contains costs mandated by the state, reimbursement for those costs shall be made pursuant to the statutory provisions noted above.
