Tips
- Per the Commercial Permit Guide, Multiple Reviews (the standard track) take up to 25 business days; an Expedited Review option is available and is not to exceed 10 business days for qualifying projects.
- Commercial permits are also the required track for any residential project of 3 or more units (apartments, condominiums, Mobile Home/RV parks) — do not use the single-family Residential Building Permit process for these.
- The Administrative Review checklist differs slightly from residential: commercial requires only one (1) set of construction documents versus two (2) for residential, but adds Environmental Programs (Notice of Intent & Request to Discharge), Well (ADWR form ff-40), and SWPPP/NOI documentation where applicable.
