  • Accessory Units (Mother-in-law Units)
    Modesto permits accessory units, sometimes called "mother-in-law" units or second units to be built on single-family lots under certain circumstances. If you are interested in adding a second unit to your lot, you are encouraged to call the Planning Division at (209) 577-5267 to determine whether your lot is suitable for a second unit.
    The City of Santa Cruz makes available a set of prototype designs for accessory units which may help you in thinking through your design. A set of these documents is available for review at the City of Modesto's Community Development front counter, or for more information please visit:
