  • Heat-loss calculation
  • Two sets of building plans to scale that describe elevations, floor plans, cross-section, and foundation details

Here are some things to keep in mind when making an application:

  • Incomplete application packages will not be processed and returned to the applicant
  • Once a permit has been reviewed by a Safety Codes Officer it cannot be released until all applicable sub trades (gas, plumbing, heating, and electrical) have obtained their permits
  • It could take 3-5 weeks for an application to be reviewed and processed 
  • You can check on the status of your permit application using your MyCity account
