Planning Commission - Mar 4, 2026
Commissioners heard that building an ADU costs roughly $550 per square foot and the process is confusing for everyday residents. Ideas floated include a plain-English checklist in English and Spanish, pre-approved plans, a sample fee sheet, monthly ADU help hours, and possibly an amnesty program for unpermitted units.
