What permits are required to increase the floor area, building height or build an extension to an existing building or structure?

A building permit is required before the extension or increase to an existing building or structure. An application form, signed and stamped plans, and supplemental documents are required for a complete application submission.

Generally, modifications and additions that increase the size of an existing building or structure or add a new building or structure on a commercial or residential property may require the following permits:

  • Commercial Addition Permit / Residential Addition Permit (Building Permit): This permit is required prior to increasing the size of an existing building or structure or adding a new structure on an existing property.
  • Electrical permit (sub-record to building permit): This permit is required for any electrical work, such as installing new outlets, wiring, or lighting fixtures.
  • Plumbing permit (sub-record to building permit): This permit is required for any changes or additions to the plumbing system, such as installing new sinks, toilets, or water heaters.
  • Mechanical permit (sub-record to building permit): This permit is required for any mechanical systems, such as HVAC or ventilation systems.
  • Fire permits: Applicable fire permits are required for any modifications, additions, or changes to a fire sprinkler system; fire alarm system, or other applicable fire-related emergency equipment and devices. Please contact the Fire Prevention office for information regarding fire permits.

In addition to these permits, there may be other permits or approvals required depending on the specific project and the City’s adopted codes and regulations. It is important to work closely with the landlord/property management company and the city’s development review team to ensure that all necessary permits and approvals are obtained before beginning any construction or renovation work.
