Key provisions · Claude summary, not statute text

Intent that local ADU and JADU ordinances enable, rather than restrict, these units.

  • Ordinances must provide for ADUs. An ADU or JADU ordinance must have the effect of providing for the creation of ADUs or JADUs.
  • No unreasonable restrictions. Provisions on unit size, parking, fees and other requirements may not be so arbitrary, excessive or burdensome as to unreasonably restrict homeowners from creating ADUs or JADUs where the ordinance authorizes them.
