Changes to existing buildings
Before you apply
Use this page to help guide you through submitting a complete application. We will explain when you need a permit, what permits you need, what your application requirements are and go over some common rules relating to your project.
Do you need a permit?
Building safety approval (Building permit)
- Any construction being done, including alterations, relocation, repair or demolition 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.
- There’s a change to the business activity resulting in a new building code classification or occupant load (ex. a warehouse changes to a vehicle repair shop). Even if there is no construction planned, you may still need a building permit.
- When upgrading or installing new mechanical equipment to meet building code (ex. 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.
For more information for when a permit is required can be found in the permit regulation. This regulation establishes rules governing building, fire, gas, electrical and plumbing permits.
A building permit is not required when the above criteria does not apply to your application, and the scope is wholly cosmetic (painting or furniture).
Review how to prepare your application for more information on preparing your application.
When do you need additional permits?
You may require additional permits depending on if it meets the rules of the Land Use Bylaw or if you are doing any additional work including electrical or plumbing.

Navigating the approval process for commercial multi-family projects
Watch a recorded Q&A on everything you need to know before starting your building permit application. Learn about common building permit application mistakes for altering a commercial space and what your clients need to know about development and building permits before renting a commercial space.
Any changes to a commercial or industrial space will need to have the appropriate planning approval in place before the Building Permit can be issued. We recommend applying prior to making your building permit application. All building permits undergo a use review upon submission to confirm that this planning approval is in place before proceeding to further review.
NOTE: If you’ve already applied for your building permit and no previous approvals have been applied for, then your building permit will remain on hold until the appropriate planning approvals have been granted. .
A Development permit may be required if:
- you are changing how the space or building will be used
- if the space does not have the appropriate planning approvals for your proposed activities
- if you are making exterior changes that do not match the approved Development Permit for the building
Please note that Development Permits are not guaranteed to be approved.
For more information on Development Permits, read the Land use Bylaw section.
If you are unsure if you need a development permit, contact the Planning Services Centre.
Separate trade permits are required for each trade (ie electrical, plumbing, gas and HVAC) and will need to be applied for by the appropriate trade contractor. Read more about hiring a contractor.
Contractors looking for more information can review the Trade Permit contractor information page for more details.

How do you pay for a permit?
For online submissions with large permit costs, there is a deposit process in place that limits the amount paid online.
Permit fees under $10,000 must be paid in full when submitting your application.
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.

Will you need professional involvement?
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).
What are the rules when designing your project?
The following information will help you prepare your building permit application, and make sure it meets the City’s requirements.
Where are you building?
Some rules may depend on the land use district (zone) you live in. Use the address search below to find your zone.
Land Use Bylaw information
All commercial and industrial spaces in Calgary require planning approval to ensure compliance with the City of Calgary’s Land Use Bylaw. This approval is based on the land use district (commonly referred to as zoning) and what the proposed activities of the space will be. The Land Use Bylaw also sets rules for building form, density, and location.
The Land Use Bylaw specifies a list of allowable uses for each land use district based on what the intent is for that location. Uses will be listed as either permitted or discretionary, but if the use is not listed in a land use district, that activity will not be allowed to operate from that location.
How the space is used will determine what use or uses best fit your business. Types of planning approval include Permitted Change of Use, Permitted with Relaxation Change of Use, and Discretionary Change of Use.
If you are making changes to the exterior of a building, be aware that changes to the how the building looks will often require a new Development Permit or Revised Plan. Changes to the parking or other elements of the property will require a Changes to Site Plan Development Permit.
If you are unsure if your scope of work requires a development permit, contact the Planning Services Centre.
Permitted or Discretionary? What’s the difference?
In the Land Use Bylaw, Uses are defined as either being Permitted or Discretionary in a Land Use District.
Permitted means that, if a use meets all the rules of the bylaw, it must be approved. The uses listed as permitted were intended for this location and have little to no impact on the surrounding community.
Permitted with Relaxation means a use that is permitted but requires a relaxation of one of more bylaw rules. Evaluations are done on a case-by-case basis to determine if the relaxation is appropriate and how it impacts the surrounding community.
Discretionary use means that the use needs to be reviewed and is evaluated against several factors including applicable policies, appropriateness of the location, the compatibility of the use with others in the surrounding area, access, parking, servicing, and sound planning principles. Each submission is reviewed on its own merit at the time of application as discretionary uses have a higher impact on the surrounding community.
You may need a development permit to operate from your preferred location if your proposed business activities do not match the current approved use. This is called a change of use development permit. You may need a development permit for other reasons, including some exterior and interior changes to the space.
Sometimes, even if your business is listed as permitted, your business activities require a relaxation to the bylaw rules. This is considered permitted with relaxation change of use and takes longer to process than a permitted change of use.
Contact the Planning Services Centre if you are unsure if the changes in operations will require new approvals.
How to apply
You can apply for your Change of Use Development Permit before, at the same time as, or after your business licence (Licence) application. We recommend applying before your Licence.
Review the sample drawings to help prepare your application.

Alberta Building Code information
This information assists business owners and contractors understand and implementing general Alberta Building Code requirements for commercial building permits. Commercial spaces must comply with the Land Use Bylaw as well as minimum requirements established in the National Building Code - Alberta Edition, 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 Alberta Fire Code also known as the 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.
Business activities are associated with a type of occupancy and governing building classification in the Alberta 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 Alberta 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.
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: a space (e.g. hospital, assisted living, nursing home) where medical treatments occur, including surgery, intensive care, and emergency medical intervention; OR a space where daily patient/resident monitoring and support occurs to assess daily functioning and cognitive awareness; the facility may also book appointments for residents, provide reminders of those appointments, provide supervision pertaining to medications and nutrition, and intervene in the event of an emergency
Residential: a space that includes sleeping accommodations such as an apartment or hotel; please note this category excludes sleeping accommodations for the purpose of care, treatment and/or involuntary detention
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 Alberta Building Code for exact wording of each category. The above information is intended to provide a general summary.
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 National Building Code (Alberta Edition).
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.
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 Alberta 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.

How to check the status of your permit
What inspections do you need?
Building permit inspections you will need
If you’ve applied for the following trade permits, you will need these inspections:
What you need to complete before you call for each plumbing inspection:
- Install and complete all plumbing drainage and venting.
- Install and connect water lines to the rest of the water distribution system.
- Properly support all drains, vents, and water lines.
- Install the bathtub/shower valve.

- Seal all piping designed for future fixtures with an approved plug or cap.
- Provide a shut off valve for all toilets.
Following an inspection, The City’s safety codes officer (SCO) may identify corrective action to comply with the National Building Code (Alberta Edition). In place of a re-inspection, the SCO may provide an option to submit a verification of compliance (VOC).
How do you book your inspections?
All contractors can book inspections online through the inspections booking system.
Our enhanced inspections booking system provides a more streamlined experience for contractors to better manage their inspections. Contractors can book, reschedule or cancel their inspections all through the online tool.
Please note, inspections can be booked up to 10 business days in advance and occur Monday to Friday from 8 a.m. to 4 p.m. The City continues to do our best to accommodate booking requests, however some dates may be unavailable due to inspection capacity.
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.
Visit building inspections for information on how to book an inspection, cancel or reschedule, permit expiry and the applicable requirements for each inspection type.
