Home renovations and basements
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?
A basement development or other interior home renovation (such as main floor renovations) requires a building permit if:
- The basement is being developed for the first time
- You are making structural changes such as moving or removing walls on any floor of the house
- You are creating new openings in interior or exterior walls (new or relocated windows, new doors)
- Exterior renovations that do not add new square footage or structures. For renovations that include a new space, see our page on additions.
Typically, interior renovations and changes to existing basements do NOT need a permit when the work consists of minor cosmetic upgrades, which includes finishes, painting and furniture.
Building safety approval (building permit)
Building safety approval is to make sure that the structure meets building safety requirements. Review the construction (building code information) section of this page for more information.
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.
Planning approval (development permit)
In most situations your interior renovation or basement development will only require a building safety approval (building permit). If your design or location does not meet land use bylaw specifications, you will also require planning approval (development permit).
To find out what your land use district is and for a list of common rules, read more in the what are the rules section.
Electrical permit
You need a separate electrical permit for all electrical installations and renovations.
If you are doing the work yourself, you may be eligible for a Homeowners Electrical Permit. Review the electrical wiring section of homeowner electrical and plumbing permits for more information.
If you are hiring someone to do the work for you, they will need to apply for the permit. Visit our hiring a contractor page for more information.
If you are a contractor, visit our trade permit contractor page for more information.
Plumbing permit
A separate plumbing permit is required for all new plumbing installations, as well as when extending or altering any existing plumbing systems.
For more information about what type of electrical work a homeowner may obtain a permit for, review the homeowners permits eligibility and plumbing permit sections.
For information for contractors, visit the trade permit contractor information page.

The engineer should be registered with APEGA- The Association of Professional Engineers and Geoscientists of Alberta. Please visit APEGA website for professional engineer’s stamp authentication requirements.

New work and replacement of "like for like" mechanical components and systems normally requires building, gas and/or electrical permits. Please see the Alberta Permit Regulation and the Calgary Building Permit Bylaw for details.

Radon
Radon is a naturally occurring gas that is invisible, odourless and tasteless. When diluted by the air around us, it does not cause problems. However, when concentrated in an enclosed space, it has been linked to serious health issues.
To test for radon in your home, you can purchase a do-it yourself test or hire a radon professional. Once your basement has been tested, if it shows that the levels of radon are above the Health Canada threshold of 200 becquerels per cubic metre (200 Bq/m3) then a radon remediation system could be installed. For more information, visit Health Canada's Guide for Radon Measurements in Residential Dwellings (Homes).
A radon remediation system rough-in installation is not a building code requirement for existing homes. If you are adding to the footprint of your home, then a radon remediation system rough-in is required for the addition. Review our additions page for more information.
For more information on radon mitigation, contact Health Canada.
If you have questions regarding installation requirements for your radon rough-in, contact the Technical Assistance Centre.
Building code questions
If you have questions or need clarification on the Building code information above, contact the Technical Assistance Centre.
For all other inquiries contact our Planning Services Centre.

What to do if the work has already been completed?
Concealed wiring procedure
If your renovation has previously been finished without proper permits, you can still apply for the permits after the work has been completed.
For an electrical permit, when the work has been concealed by drywall, you are required to follow the concealed wiring procedure. A homeowner’s permit cannot be issued for concealed wiring completed without proper permits. To have the inspection done, the owner must hire a licensed electrical contractor. The contractor will have to obtain an electrical permit and check that the wiring complies with electrical codes. However, the homeowner is responsible for any previously concealed electrical wiring.
Note: There is a possibility the inspector may ask for drywall to be removed to complete their inspection.
