Adding a secondary suite
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?
Yes, you will need:
- a building permit
- a separate electrical permit for all electrical installations and renovations
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.
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.
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)
If secondary suites are listed as discretionary in your district, or your design or location does not meet land use bylaw specifications, you will also require planning approval (development permit). To find out if you need a development permit, search your address using the tool in where are you building?
Plumbing permit
A separate plumbing permit is required for all new plumbing installations, as well as when extending or altering any existing plumbing systems.

Secondary Suite Incentive Program
The Secondary Suite Incentive Program supports safe housing for all. The program will provide up to $10,000 per qualifying homeowner.
What is a secondary suite?
A self-contained residence with two or more rooms and includes a kitchen, living, sleeping and sanitary facilities.
All suites must have:
- Bedrooms with proper egress windows
- A separate bathroom
- Separate cooking facilities
- An entrance that is accessible from outside without passing through the main dwelling unit. A shared stairwell is acceptable, but each unit must have a private entrance.
Permit costs and timelines
Find out which permits you need to complete your secondary suite, how much they will cost, and the approval timelines.
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?
General suite rules
Number of suites on a property
- There can only be one secondary suite within each dwelling unit.
- A backyard suite and a secondary suite cannot be located on the same property
- You must indicate on your plans:
- The location of the amenity space for the suite
- The location and size of parking being provided for the suite
If you have questions or need clarification on the Land Use Bylaw rules, or have general permit questions, please contact the Planning Services Centre.
Construction information (building code) to consider when designing your building
The current National Building Code – Alberta Edition identifies safety considerations that must be in place in any secondary suite.
Ceiling and door heights
There must be a minimum floor to ceiling height of 1.95 m for basement suites.
- Ceiling heights can be reduced to 1.85 m where ductwork and beams make drop ceilings necessary.
- Doors within the suite may be reduced to 1.89 m where required.
Separation of suites
Preventing the spread of smoke and fire is essential for safety. The building code requires the installation of a smoke tight separation between the main residence and suite, in any common spaces and/or the furnace room.
Doors installed in common spaces, furnace room or between dwellings must be solid core wood at least 45mm thick and have a self-closing device on the door.
- Installing a minimum of 12.7 mm (½") thick drywall on the ceiling and on both sides of wall studs that separate a suite from main residence. All drywall joints must be taped and filled with drywall compound to provide a smoke tight joint.
- Installing a minimum 12.7 mm (1/2”) thick drywall on the ceiling and on both sides of wall studs of the mechanical room. All drywall joints must be taped and filled with drywall compound to provide a smoke tight joint, and any penetrations must be appropriately sealed.
Additional requirements for smoke-tight separation
- The mechanical room must have a solid door with a self-closing device. The path of travel to an exit door cannot pass through a mechanical room.
- Any services such as pipes or ductwork, which pass through a protective separation, need to be tightly fitted and sealed with drywall compound or sealant.
- In retrofit situations, existing mechanical rooms may have obstructions that make a smoke-tight separation difficult to construct. One option may be to remove all existing HVAC ducts to ease the installation of 12.7 mm (½”) drywall. Once the separation is constructed, new holes may be cut where required to install ductwork.
- Double wall (B-Vent) chimneys will require minimum 25.4 mm (1”) clearance to ½” drywall and tightly fitted sheet metal fire stop to maintain the smoke separation.
- Single wall vent connectors will require minimum 152.4 mm (6”) clearance to ½” drywall.
Sound proofing
Each dwelling must be separated and constructed using sound proofing materials to minimize noise transfer between units including:
- Filling joist spaces with sound-absorbing material of no less than 150mm nominal thickness.
- Filling stud spaces with sound-absorbing material, ensuring there is a resilient channel on one side of the separation spaced 400 or 600 mm o.c.
- Having no less than 12.7 mm thick gypsum board on the ceiling and both sides of the walls .
- Providing an STC rating of not less than 43, (refer to NBC-AE) or a separating assembly and adjoining constructions, which together provide an ASTC rating of not less than 40.
Smoke and carbon monoxide alarms
Smoke alarms
- Must be installed at, or near, the ceiling of each floor level in both the primary dwelling and secondary suite.
- Are required in each bedroom, common space and any supplementary spaces including mechanical (furnace) rooms.
- Must be permanently wired to the electrical panel through a circuit that contains lighting or a mix of lighting and receptacles, if that circuit is protected by an arc fault circuit interrupter and/or a ground fault circuit interrupter, the smoke alarms must contain an integral battery (10-year battery) as a secondary supply source.
- Must be interconnected, so the activation of one smoke alarm will cause all units in the secondary suite and a minimum of one smoke alarm to sound in the main residence.
Carbon monoxide alarms
- Should be centrally located in the primary dwelling, the secondary suite, common spaces and mechanical room.
- Should be installed at the height specified by the manufacturer and located within 5 m (16’5”) of any bedrooms.
- Must be permanently wired to the electrical panel through a circuit that contains lighting or a mix of lighting and receptacles, if that circuit is protected by an arc fault circuit interrupter and/or a ground fault circuit interrupter, the carbon monoxide alarm must contain an integral battery (10 year battery) as a secondary supply source.
- Must be interconnected, so the activation of one carbon monoxide alarm will cause all units in the secondary suite and a minimum of one carbon monoxide alarm to sound in the main residence.
An electrical permit is required if installing additional wired smoke alarms, carbon monoxide alarms and combination smoke/carbon monoxide alarms.
Entry and exit points
The main residence and suite must have at least one exit that leads directly outside. This may be a door that leads to an exterior stair or a door to a common set of interior stairs that is separated from both the main residence and suite.
- A stairway used in an exit requires a minimum width of 860 mm and must have at least one handrail.
- Handrails should be mounted between 865 mm and 1070 mm above the stair. The height is measured vertically from the front edge of the stair tread.
- At least one light fixture that can be switched both on and off at the top and bottom of the stairs is required.
- A landing must be provided at the top and bottom of all stairs. The landing must be at least 860 mm long and at least as wide as the stairs.
- Doors serving the exit are required to be a minimum of 810 mm wide and 1.89 m high. Utility rooms, laundry rooms, furnace rooms and all other doors leading to the exit must also be at least 810 mm wide.
Bedroom egress windows
Each bedroom must have at least one window that can be fully opened and used to escape during an emergency, such as a fire. Information about the window, including if it is existing, proposed, the size and type must be included on your plans.
- The windows must be openable without the use of keys, tools, or special knowledge and without the removal of sashes or hardware.
- The window must have an unobstructed opening of 0.35 m2 (3.8 ft2) in area and no dimension less than 380 mm (15").
- If a casement-type window is used, it must swing open a full 90 degrees.
- Refer to Building Advisory A19-005 - Egress Window Guidelines for more details.
Casement windows
Casement windows must open a full 90 degrees when a window is required.
Horizontal sliding window
Vertical sliding window
Awning window
Exterior stairways and protection of secondary suite exits
You must ensure your suite tenants can safely exit in the event of a fire or emergency. There are additional requirements to consider when the only exit for a suite is served by an exterior staircase, where a window or opening is located directly above the stairway:
- Option A: Installing glass block or wired glass in fixed steel frames on the windows of the primary home.
- Option B: Constructing a roof over the entirety of the exterior exit stair out of solid material such as wood, metal or concrete.
Option A
If you install glass block or wired glass:
- Windows that are less than 3 m horizontally and less than 10 m below or less than 5 m above the exit stair need to be protected.
- Windows on the primary entrance that do not expose to the stairwell do not need protection.
- Only fixed, non-operable windows can be protected in this way.
- Bedroom windows must be operable.
Option B
Option B shows an exterior stairwell with a roof providing protection from the window above it.
More information on unenclosed exterior stairs can be found on the protection of openings near unenclosedexterior stairs and ramps advisory.
New exterior stairwells and engineering
The National Building Code (Alberta Edition) requires all foundation footings in Calgary to have at least 1.2 m of ground cover for protection.
- New exterior exit stairs must include a shallow foundation design by a registered professional engineer since stairwell excavation impacts the required frost cover.
- Retaining walls required alongside the new staircase opening often retain greater than 1 m of soil. In these cases, the retaining wall may be required to be included in the engineered design.
Plumbing
Secondary suites must have:
- A supply of hot water and at least one kitchen sink, bathroom sink, toilet and a bathtub or shower.
- A back-flow prevention device on the branch drains of the sanitary sewer line.
For more information, refer to the following advisories:
Electrical
A common electrical panel can serve both suites, provided there are no shared branch circuits between the suites. It is recommended the electrical panel be in a common area, or that each tenant has access to the electrical panel.
- Use the secondary suite electrical load calculation sheet to ensure your current electrical service is adequate.
- Before an electrical permit rough-in inspection occurs, the form should be emailed to us.
- If the main electrical service must be increased from 60 amps, 100 amps, or 200 - amp service, please have your Contractor contact ENMAX.
Airport vicinity protection area (AVPA)
On a property located inside the airport vicinity protection area (AVPA), the suite must be located in the basement of an existing single family development.
Chat with us, or contact the Planning Services Centre at 403-268-5311 for more information about secondary suites in the AVPA.

Suites FAQs
Suite registry FAQ
What is the secondary suite registry?
The secondary suite registry is an online, searchable list identifying legal and safe secondary suites in Calgary. These suites have been registered and inspected to meet Alberta’s safety code requirements. View the suite registry bylaw and go to secondarysuites.calgary.ca to view the registry.
What is the goal of the registry?
The registry aims to build awareness with Calgarians about the importance of public safety, and the safety features of a legal secondary suite. Suites that have been inspected by The City and meet the requirements under Alberta’s safety codes provide the necessary measures to help protect lives.
What are the advantages of the registry and sticker for owners?
Registered secondary suites are listed on The City’s website and receive a numbered sticker that can be posted at the main entrance of the suite. Owners can use the registry and sticker as a means to promote their suite to current and future residents.
Is there a cost to be on the registry?
Not currently, however, in January 2022, we will reinstate fees for the suite registry. The registry program is intended to promote the importance of safe secondary suites for Calgarians.
How do I get a secondary suite sticker for my suite?
Please note it will take two to three weeks after the final inspection to receive your sticker in the mail.
Where do I place the sticker on my property?
We recommend placing the stickers on the entry point of the suite. This informs current and future residents that suite is part of The City’s registry program.
If the property is sold, does the registry transfer to the new owner?
Yes. The registry is connected to the address containing the legal and safe secondary suite.
How long is the sticker valid for?
There is no expiry date.
Can I make modifications to my secondary suite after the building permit is approved?
Any changes to your secondary suite could require additional permits and inspections. To ensure modifications meet the requirements of Alberta’s safety codes and do not alter the safety features of your suite, contact The City’s Planning Services Centre at 403-268-5311 for assistance.
What penalties might I face for owning an unsafe suite?
Safety is always top priority for The City. Our inspectors work collaboratively with secondary suite owners, and we determine appropriate timelines to complete work. However, if owners of illegal suites do not comply with minimum safety standards, we may take legal action.
Can I be removed from the registry?
The City investigates all complaints, should your secondary suite be found to no longer comply with Alberta’s safety codes, your suite will be removed from the registry.
Suite addressing FAQ
The City of Calgary requires the assignment of a separate address for secondary suites to supplement the basic address of the main dwelling. The identifier for the secondary suite may be alphabetical or numeric. Suite numbers are shown at the start of the address for the following purposes:
Emergency response and wayfinding
If an emergency event occurs in the secondary suite, every second counts and a precise location will assist the emergency responders to locate the suite.
Current and future utility hookups
Utility hookups require the exact suite address where the utilities will be hooked up and for the utility bill to be sent.
Applications for future business licences
A requirement of a business licence is to have the exact suite address to where the business will be operating. Although there might not be a business operating out of the secondary suite at this time, an address will still be created to enable a business to be licenced at the suite when needed.
Applications for future short-term rentals
Although the secondary suite might not be used as a short-term rental at this time, a new address will still be created to enable a suite to be licenced for a short-term rental when needed. The licence requires the exact suite address and not the main dwelling address.
Canada Post and other mail delivery services
Although not a City of Calgary requirement, having a separate address for the secondary suite will assist in the delivery of mail to the correct dwelling unit.
Suite density FAQ
Residential development: Understanding secondary and backyard suites’ impacts on growth in established areas
At a recent Partners in planning session, hosted by the federation of Calgary communities, several questions were asked on understanding suites’ impacts within an established area.
What is the difference between a secondary or backyard suite and a dwelling unit?
A dwelling unit is the primary home for the property. Dwelling units come in many forms like an apartment, single-detached house, semi-detached house or rowhouse.
Suites are spaces used as separate living quarters from the primary home on a property. They can take form as a secondary suite or a backyard suite.
Secondary suites are located within the primary home. They are typically located in the basement but may also be located on the main or upper floors or above an attached garage.
Backyard suites are physically separated from the home and located in the property’s backyard. They are typically built on top of a detached garage but can also be on the ground floor attached to a detached garage or in an independent structure.
A suite must be approved with a primary home. They are not separate dwelling units, meaning these suites can’t be subdivided or sold separately from the primary home.
Why are suites allowed in single-detached/ R-C1 communities?
Suites are allowed in all low-density residential districts (except the R-MH District) in the City of Calgary. City Council amended the land use bylaw in 2018 to allow for suites throughout the city.
How does the MDP estimate population based on number of units?
The table below provides a common method for calculating population per hectare, by each of the key dwelling unit types (low, medium, high) and the occupancy rate, in established areas.
Why are suites allowed in single-detached/ R-C1 communities?
Secondary suites are allowed in all residential districts in the City of Calgary. City Council amended the land use bylaw in 2018 to allow for secondary suites throughout the city.
Will my property tax increase with the development of a secondary suite or backyard suite?
Property tax is calculated and billed annually using the property’s assessed value, as found on your property assessment notice, and the Council-approved property tax rate. Home improvement projects (i.e. basement development) or adding livable space to your home could increase your property taxes. If you have questions about property tax, contact 311.
Are levies charged on suites in the established area?
Developers pay for the costs of infrastructure within a development site that they’re building but exempts backyard and secondary suites, following the rules outline in the off-site levy bylaw. For established areas, levies are collected for the treatment plant levy. More information can be found on our off-site levy page.
What are the parking requirements for suites?
Under the current Land Use Bylaw, suites require a minimum of one motor vehicle parking stall. This requirement is reduced in some land use districts where certain conditions are met such as a limited floor area, proximity to transit, provision of bicycle parking or where the main dwelling has 2 or more parking stalls. A relaxation in parking minimums may be considered based on proximity to city centre, amenities and public transit. For more information, please refer to the policy to guide discretion for secondary suites and backyard suites.
Are suites considered in The Municipal Development Plan (MDP)’s density calculation?
Yes, indirectly. The Municipal Development Plan has intensity targets for select areas of the city, including activity centres, main streets, transit station areas and new communities. These targets are measured as people and jobs per hectare, which would include people living in suites in the calculation. These targets are not requirements, but rather aspirations.
How does the MDP estimate population based on number of units?
The table below provides a common method for calculating population per hectare, by each of the key dwelling unit types (low, medium, high) and the occupancy rate, in established areas.
Occupancy rates are based on observed census data, and the population of suites is accounted for in the occupancy rate of low-density dwelling types.
How come suites are not counted towards density?
Density is calculated by the number of primary dwellings on a parcel of land and does not include backyard or secondary suites. These suites do not increase the number of primarily dwelling units on a property as they are created either within the existing home or as part of the backyard.
For example, R-C1 districts allows for single-detached homes as well as secondary suites. A homeowner may choose to convert their basement into a legalized suite, which offers more housing choice in the community but does not increase the number of primary dwelling units onto the property.
What about districts where more than two dwelling units can be on a parcel of land? In the R-CG district, a maximum density is established to regulate the number of homes on a parcel, rather than the type of home. This is because a range of dwelling units may be found in a single building (i.e. a rowhouse may include three, four, five or more dwelling units) and more than one building containing dwelling units may be built on a parcel. In this district, there may be one suite per dwelling, but those suites do not count toward the maximum allowable density. This is done to allow for suites, but not allow for additional dwelling units beyond the maximum density.
Disclaimer: This information has no legal status and cannot be used as an official interpretation of the various bylaws, codes and regulations currently in effect. The City of Calgary accepts no responsibility to persons relying solely on this information. Web pages are updated periodically.
| Residential type | Units per hectare | Occupancy rates | People per hecare |
|---|---|---|---|
| Low density | 17-28 | 2.8 | 50-80 |
| Medium density | 25-2008 | 2.4 | 62-500 |
| High density | 225-1041 | 1.6 | 360-1667 |
Occupancy rates are based on observed census data, and the population of suites is accounted for in the occupancy rate of low-density dwelling types.
Suite services FAQ
Does my secondary suite get its own blue, black and green carts?
- Any residential dwelling which currently receives City residential blue, black and green cart service and has a secondary suite can add additional carts to ensure there is adequate cart capacity to sort your household waste properly.
- More information on who qualifies for additional carts and how to request them please visit this page.
