A Commercial Building Alteration Permit is required before making any changes to an existing commercial, industrial, mixed-use, or qualifying residential building. This includes any projects that modify an existing building without increasing its footprint or overall volume.

What it allows you to do:

  • Alter the interior or exterior of an existing building
  • Recongigure interior spaces by adding or removing walls
  • Renovate or remodel an existing commercial building

Example projects:

  • Remodel an office space
  • Renovate a restaurant or retail store
  • Convert an existing space for a new tenant
  • Reconfigure interior walls or room layouts
