How the Occupancy Process Actually Runs
When a change of occupancy is coming, the owner or managing agent notifies the Building Official, and the city inspects the property to check it still complies with the code. Failing to report a change of occupancy is itself a violation, and the duty falls on real estate agents and brokers as well as owners, so this is not something that quietly gets missed.
On the current fee schedule, an application for a one- or two-family dwelling costs $100 and includes two inspections. The permit itself is $50 to issue. The fees cover the first reinspection if one is needed, and each reinspection after that adds $50. Extensions and conditional permits are $50 each. Utilities have to be on at the time of inspection, which is a real obstacle for a vacant house. Confirm current fees with the Building Division rather than relying on any figure you read online, including this one.
