Step 1: Review the rules, application process, and fees for your project

Do I need a permit?

  • A building permit is required if any of these conditions apply:
    • There’s a change to the business activity resulting in a new building code classification or occupant load (e.g. a warehouse changes to a vehicle repair shop). Even if there is no construction planned, a building permit may still be required.
    • Any construction is being done, including alterations to structural and non-structural walls. If you’re making changes to mechanical, plumbing, gas or electrical work, you may need a building permit and additional trade permits.
    • When upgrading or installing new mechanical equipment to meet building code (e.g. a car detailing business to an engine repair business; using a forklift in a warehouse may require additional ventilation; adding or modifying cooking equipment).
    • You are the first tenant in a new building.
    • Alberta Health Services must review the application; some examples are restaurants, daycares, pools, hair salons, massage centers, tattoo parlors, and nail salons.
  • A building permit is NOT required when the above criteria does not apply to your application, and the scope is cosmetic (painting or furniture).
  • A development permit may be required, before applying for a building permit. If you are unsure if you need a development permit first, contact the Planning Services Centre.

Payment Process

Online submissions

For online submissions with large permit costs, there is a deposit process in place that limits the amount paid online.  For building permit fees over $10,000, only 25% of the base permit fee will be charged as an initial deposit, up to a maximum of $10,000. If 25% of the building permit base fee exceeds $10,000, you will be contacted to make payment for the remaining permit fee balance and any applicable additional fees (i.e. partial permit, lot grades, SCC, etc.) For example, if 25% of the permit fee is $25,000, you will pay a $10,000 deposit online and our Cash Office will contact you the next business day to make the payment for the remaining $15,000 of the deposit.

Step 2: Prepare

Preparing your application

The building permit checklist will indicate the plans and documents that are required. Plans need to include enough detail to clearly convey the entire scope of intended work, and include information needed to guide the construction process.

All areas covered by the current Building Code including mechanical, plumbing and electrical systems, washrooms and fire ratings should be included in your plans. Submitting a comprehensive set of plans will result in a specific and accurate review process, leading to efficient approval of the building permit application.

Quick releases

 To help plan your project, determine if your permit qualifies for quick release:

Professional architects or engineers

An architect or professional engineer may be required to design and inspect your project. Refer to the current Building Code, Division C, Section 2.4.2 or a consultant to determine if professional involvement is required. Where professional involvement is required, plans or documents must be stamped by the corresponding professional(s).​​

Planning approval requirements

All building permits undergo a use review to ensure the proposed construction has appropriate planning approval. Planning approval can be achieved through a development permit. If no previous approvals have been applied for, then your building permit will remain on hold until the appropriate use approvals have been granted. You can find more information about the Development Permit Process through the linked page. 

Building Code requirements

Building Code information

This information assists business owners and contractors understand and implementing general current Building Code requirements for commercial building permits. Commercial spaces must comply with the Land Use Bylaw as well as minimum requirements established in the current Building Code, including applicable standards for safety of the public and building occupants, health, accessibility, energy, fire, and structural integrity. Commercial spaces must also comply with the National Fire Code (Alberta Edition) also known as the 2019 National Fire Code (Alberta Edition). Businesses are responsible for following the rules and regulations of all applicable governing bodies prior to using the space.

Business owners and contractors should consult a design professional before financially committing to a location. The cost to make necessary upgrades or changes may be expensive. The City of Calgary does not determine who should coordinate or pay for upgrades.

Some activities have very specific code requirements, including restaurants.

Building code classification

Business activities are associated with a type of occupancy and governing building classification in the current Building Code. Classification is determined by building size (footprint area and number of storeys), construction type (wood or concrete and steel), the need for a sprinkler and fire alarm system, and type of occupancy.

Depending on how the building is classified, changes and upgrades may be necessary to accommodate the proposed activity. For example, a building without sprinklers may be suitable for a retail store, but not suitable for a restaurant when taking into consideration the size, construction type, and mechanical ventilation.

Knowing the building classification will assist with design and construction, by helping to determine:

  • Fire ratings of walls, floors, mezzanines and roofs
  • Construction type (combustible, non-combustible or combination of both)
  • If sprinkler and fire alarm systems are required

The current Building Code also determines:

  • Maximum occupant load
  • Barrier free accessibility and washroom design
  • Required exiting
  • Fire alarm and detection requirements

Due to the complexity of interpreting the classification, you may need to engage with a consultant that can conduct a building code analysis in order to identify the building classification and the rules related to that class before preparing your plans and documents.

Ensure your building classification is clearly indicated on your plans. Providing this information reduces delays in your application review.

Code classification descriptions

On your building permit application, you must indicate one of the following building occupancies:

Assembly: a space (e.g. arena, theatre, restaurant, day care) where people gather for civic, political, travel, religious, social, educational, recreational or similar purposes, including consumption of food or drink

Detention: a space where people are held under restraint or are not self-sufficient due to security measures

Care: the use of a building or part thereof where the provision of services other than treatment by or through care facility management is provided to residents who require these services because of cognitive, physical or behavioural limitations.

Treatment: use of a building or part thereof for the provision of medical or other health-related intervention to persons, and where overnight accommodation is available to facilitate the treatment.

Residential: use of a building or part thereof by persons for whom sleeping accommodation is provided but who are not harboured for the purpose of receiving care or treatment and are not involuntarily detained.

Personal Service/Office/Business: a space (e.g. banks, beauty salons, dental offices, medical offices) used for business transactions, including provision of professional or personal services

Mercantile/Retail: a space including, but not limited to, exhibition halls, department stores and markets that are used to display or sell retail goods

Industrial: a space used for the assembly, fabrication, manufacture, processing, repair or storage of goods and materials

Please see the current Building Code for exact wording of each category. The above information is intended to provide a general summary.

Barrier free design

Codes addressing accessibility, or barrier-free design, allow safe access to buildings and facilities for all people. Reasonable access to facilities is required to ensure that everyone has the same opportunities to be active, independent and safe within the community.

The rules for barrier-free design are in section 3.8 of the current Building Code. To help explain this material, the Alberta Safety Codes Council created a barrier-free design guide.

Access Design Standard - is required to be applied ONLY on City of Calgary owned / operated facilities – please speak with the project manager for the City owned project you are working on for details

If the physical layout of the building makes it difficult to provide barrier-free access and/or facilities, you can apply for a relaxation with Alberta Municipal Affairs.

National Energy Code of Canada for buildings

If you are constructing a new building or an addition (including second floors and mezzanines), your design will need to comply with the National Energy Code of Canada for Buildings (NECB) or the current Building Code section 9.36.

Buildings that were constructed to meet the National Energy Code still require compliance when undergoing renovations or improvements. This may include:

  • Building envelope: requirements for roofs, walls and windows to control heat loss and air leaks.
  • Heating, ventilation and air conditioning (HVAC): efficiency of heating and cooling equipment
  • Water heating: efficiency of equipment and controls
  • Lighting: number and type of lighting fixtures and controls

Visit National Energy Code of Canada for Buildings for more information about how it may affect your business.

Step 3: Apply

To apply online, you need a myID account. Create a myID account.

We’re currently experiencing higher than seasonal application volumes, we apologize for delays. To check the status of your permit, go to and enter in your Job Access Code (JAC) number

Apply in person

Once you have gathered all required documents, you can apply for your permit in person by visiting the Planning Services Centre.

Complete Application Requirement

An application for a permit may be refused if, within ninety (90) days from the date of receipt, adequate information and documentation is not supplied as requested by the Safety Codes Officer. Should a permit be considered for refusal the applicant will be given notification in writing and 30 days to resubmit the missing information. For more information, please review Building Advisory A19-002 Building Permit Complete Application

Step 4: Track

After you submit your application online, you will get a confirmation email with a Job Access Code (JAC).

To track your application and check its status, enter your Job Access Code in Vista.

If you need help or have questions, contact our Planning Services Centre

Revisions and resubmissions

A resubmission may be requested by your plans examiner prior to the release of your building permit. To submit the requested documents, please go to, and sign in with your myID account. Once you reach step 2 of this application process, you will select the "revisions, resubmission, and inspection documents" option to progress with your resubmission. This process is also applicable when submitting a revision to an already issued building permit.

Step 5: Changes

How long is my permit valid for?

Building permits are valid for 6 months after the date of issuance. If an inspection occurs during this time, then the permit will continue to be valid for another 6 months from the date of the last inspection. Inspections can not be booked once a permit has expired. The permit must be reinstated before another inspection can occur. 

Step 6: Inspect

Why do you need an inspection?

Inspections are part of the approval process and are included in the permit price. Your permit is not complete until your work has passed all required inspections.

Inspectors verify that your completed work meets safety or approval standards and they can assist if you encounter problems with your project. Having permits approved and completed allows future buyers to verify that your work was inspected by The City. Remember, any work completed on the building is ultimately the owner’s responsibility. If you’re working with a contractor, setting your expectations at the beginning of the project in a written contract is a good way to protect your investment. For more tips, visit hiring a contractor.

Do I require an occupancy inspection?

An occupancy permit​ is the final approval indicating that the building is safe to occupy. The building safety codes officer will review the scope of work to determine if an occupancy permit is required. If required, the building safety codes officer will provide an application for occupancy form to the general contractor at the time of inspection. If occupancy is granted, the building inspector will leave the signed occupancy permit with the contractor on site. New businesses will need to arrange for a business licence after they have received their occupancy permit. ​​
