Most single-family properties can accommodate additions. The development criteria are based upon the zoning designation of your property. You can obtain or verify your property's zoning information online by visiting the City's interactive GIS map and searching by street address or by Assessor’s Parcel Number (APN). When these development standards are applied to your property, they will determine the maximum size and configuration of the home on your property. Refer to Development Code Section 22.08.040 for development standards.
Some second-story additions, and all additions that increase the size of the house by more than 50% require Planning Commission approval. Contact the Planning Division for initial inquiries and more information by submitting online through the Planning inquiry form or by making an appointment with the Planning Division.
