Investigate the address as a proposed new use
Prepare a room-by-room account of the intended work: consultations, administration, storage, staff meetings, or patient attendance. Compare it with the previous operation and identify even small changes. A remote-first service can still raise premises questions if it adds staff, equipment, or visits that were not part of the earlier arrangement.
The Santa Rosa permitting guide distinguishes land-use permission, construction review, and business-tax registration. Bring the proposed activity and change of tenancy to city staff rather than asking only whether the address already has a license. Confirm the applicable sequence before paying for improvements. Keep the city's response specific to the described facts. If the business plan later changes, review whether that response still addresses what will actually happen at the property.
