When is a permit required for a change of use of a building?

A permit is required for a change of use of a building whenever the use of the space is altered because such changes can impact safety, accessibility, and compliance with the building code. Changing the use of a space may involve different requirements for fire safety, occupancy load, plumbing, electrical systems, and other building systems that need to be reassessed to ensure they meet current codes and standards.

For example, converting a residential property into a commercial space may require adjustments to meet the needs of the new use, including parking availability, egress, and health and safety regulations. These considerations are essential for protecting the occupants and the public and ensuring that the building can accommodate the new activities.

In contrast, changes tied to the sale of a building, limitations to commercial properties, or structural changes alone do not automatically trigger the need for a permit for a change of use. Only the alteration of the building’s intended function necessitates this permit to ensure all regulatory requirements are satisfied.
