Before you apply

This guide will help you submit a complete application and avoid delays in permit processing. It outlines the minimum information required for your project to move forward.

It explains:

  • when you need a permit
  • what permits you need
  • what your application requirements are
  • some common rules relating to your project

It doesn't:

  • limit your design choices
  • provide specific advice on Code compliance
  • apply to renovations or additions

Note: if this information is too technical, we recommend hiring a professional to assist you with your application.

This guide focuses on rowhouses with up to four units. A rowhouse has each of the at-grade main entrances facing the street. If your project includes secondary suites and there are more than five units, you require a firewall for this Guide to apply. It does not apply to renovations or additions. It specifically applies to buildings that contain up to four attached, non-stacked dwellings within the scope of Part 9 not requiring professional involvement. 

Building permit process

The building permit process is based on the Safety Codes Act, Permit Regulation and National Building Code – Alberta Edition (NBC (AE)). Plan reviews and site inspections are provided to ensure all Calgarians are safe. Trade permits for electrical, plumbing, gas and mechanical may be required. 

For more information about the building permit process, please read our guidelines and common questions. 

What you need for a successful application

To ensure your application is complete follow these three tips: 

  • Ensure completeness

    Double-check that all required documents, plans and fees are included at the time of submission to avoid delays. You will find information in the required documents below.

  • Respond to notifications promptly

    If you receive a request for additional information or a reminder, address it as soon as possible.

    Building permit process

  • Track application

    Monitor your email and the online portal for updates on the status of your application. Remember to check your Junk Mail and Spam folders, as important emails may sometimes be filtered there.

Application type: Rowhouses with up to four units

This Guide to a Complete Application focuses on rowhouses with up to four units.  If your project includes secondary suites and there are more than five units, you require a firewall for this Guide to apply. Information about the firewall requirements is shared below.

  • Firewall drawings

    Firewalls must be reviewed by a professional. The firewall designs must have engineering stamps and sealed drawings due to their unique construction and structural requirements. Refer to technical requirements below for specific Code articles and detailed design information. While the remainder of the building may typically be done without professional involvement, professionally stamped engineering drawings are required for the firewall including structural supports and associated details.

  • Firewall placement

    Firewalls divide a building into separate buildings. This creates new buildings with their own distinct entrance requirements. This must be taken into consideration when placing the building on site relating to separate services, entrances and firefighting access.

  • Firewall construction materials

    Firewalls must be made of non-combustible construction materials. Any materials attached to the firewall, including insulation and cladding, must also be non-combustible materials

Application requirements

Owners, professionals, designers and contractors must comply with all requirements of the NBC (AE), National Energy Code of Canada for Buildings, ASHRAE and the Alberta Safety Codes Act and associated regulations.

Fees

Fees are calculated based on the permit/projects Prevailing Market Value (PMV).

 

Notes

  • Your application is considered incomplete until the fees are paid in full. 
  • The minimum 25% (or $10,000 deposit for Building Permits with fees over $10,000) needs to be paid for any partial permit review to occur.
  • A partial permit cannot be issued until fees are paid in full. However, a review for a partial permit can proceed without fees being paid in full.

  • Building code

    View copies of all current Codes and standards on the Government of Alberta website.

Drawings and documents

You must provide the complete drawing sets listed below. A separate drawing set is required for each building and permit. A detached garage may be included on the permit of the building closest to it, or it may be applied for as its own permit.  Including it on the permit of the building closest to it may impact occupancy for the residential building because it is tied to the completion of the garage.

All drawings must be to professional standard outlined in the NBC (AE). 

Before uploading the documents for your permit application, please review our digital permit application criteria. The plans and documents that you upload must meet The City’s digital file criteria to facilitate quicker application review and approval. 

Professional schedules

Professional involvement may be required if the building has a firewall and secondary suites.

NBC (AE) Div C, 2.4.2. Schedules of Professional Involvement

Provide the following Professional Schedules at the time of application:

Specific fire resistance ratings must be indicated for wall assemblies and structural components. Reference to Appendix D, the Fire and Sound tables or ULC listings are needed for any assemblies with required ratings.  
  • Floor plans must show all doors, windows and layouts to determine means of egress and exits.
  • Firewalls divide a structure into separate buildings and require significant engineering.
