California note
Union City business licenses include a zoning review
Union City business license work includes more than payment. If the business location is inside city limits, Planning reviews the use for zoning compliance before the license is finished.
That makes the address important right away. A home office, warehouse, retail shop, food business, contractor yard, or office suite may each fit different zoning rules. A use that sounds simple can still need review if customers visit, equipment is stored, signs change, or the space was used for something else before.
Finance handles the license payment side, while Building handles permit questions for construction, tenant work, and inspections. The permit directory is useful when the work also touches alarms, fire review, encroachments, grading, transportation, events, or home improvements.
Start with the proposed address, business activity, owner contact, and any planned work to the space. If the address is not in Union City limits, use the right city or county office instead.
