WHAT PERMITS ARE REQUIRED TO LEGALIZE A SECONDARY SUITE IN CALGARY?
Calgary requires several permits to legalize a secondary suite. Each has a distinct role in the process.
Legalizing or building a secondary suite in Calgary often requires multiple permits. At minimum:
Development Permit – required if your property is in a discretionary zone or doesn’t meet land use rules
Building Permit – mandatory for all structural or fire/life safety modifications
Electrical Permit – for all electrical work including smoke alarms and kitchen wiring
Plumbing Permit – for new or altered bathrooms, kitchens, drainage
Improper sequencing or missing documentation can delay approvals or cause rejections.
STEP-BY-STEP SECONDARY SUITE BUILDING PERMIT PROCESS IN CALGARY
This is the typical process for obtaining suite-related permits in the correct order.
Step 1: Zoning Check and Development Permit
Step 2: Site Assessment & Drawings
Step 3: Building Permit Application
-
Confirm if your land use district permits suites by right
-
If not, apply for a discretionary Development Permit (DP)
-
Assess your current suite or layout plan
-
Create floor plans, site plans, and ensure code compliance (egress, ceiling height, separation)
-
Complete all forms and documentation
-
Submit to the City including plans and safety details
Step 4: Trade Permits (Electrical and Plumbing)
Step 5: Construction & Inspections
Step 6: Permit Closure & Registration
-
Required for new circuits, alarms, fixtures, drains, or ventilation
-
Apply via licensed trades or as homeowner with correct forms
-
Start work after permits issued
-
Book and pass framing, insulation, and final inspections
-
Once passed, close all permits
-
Register your suite with the City of Calgary (if applicable)
WHY PERMIT TIMING AND SEQUENCE MATTER
Even small missteps in the permit order can cause delays, failed inspections, or extra costs.
-
Submitting permits too early can lead to rejection if zoning isn’t approved
-
Skipping drawings or inspections forces rework mid-construction
-
Starting without full scope leads to “stop work” notices from the City
-
Trade permits depend on approved building permit details
We follow the correct sequence, so permits move forward — not back to the drawing board.
WHY SECONDARY SUITE PERMITS GET REJECTED OR DELAYED
Most delays or rejections are caused by missing documentation, incorrect permit timing, or failure to meet building code standards.
-
Submitting generic or outdated drawings not matched to actual site conditions
-
Floor plans lacking required dimensions, egress window specs, or fire safety notations
-
Applying for a building permit before obtaining zoning/development approval
-
Failing to schedule or pass mandatory inspections during construction
-
Omitting smoke alarm interconnectivity or proper separation for furnace/mechanical rooms
-
Using contractor-prepared plans that don’t follow City templates or code specifics
-
Misunderstanding which elements are code-required vs discretionary upgrades
-
Unclear parking layout or amenity space on site plans
-
Missing declarations or incomplete trade permit info (e.g. electrical panel scope)
We review every drawing and form before submission, align documents with inspector expectations, and help ensure your permit path moves forward without costly revisions or delays.
WHY CALGARY REQUIRES THESE PERMITS FOR SECONDARY SUITES
Permits protect tenants, property value, and your legal status as a landlord.
Avoid legal and financial risk
Operating a suite without proper permits can lead to enforcement actions, insurance denial, or civil liability.
Support resale value and financing
A legal, documented suite increases your home’s appraised value and helps with mortgage approvals.
Ensure fire and life safety compliance
Permits verify installation of egress windows, fire-rated separation, smoke alarms, and safe mechanical systems.
Gain peace of mind as a landlord
You’ll know your suite is safe, approved, and no longer at risk of shutdown.
Qualify for suite registry listing
Only suites with closed permits and inspections can be registered with the City of Calgary.
Permits are not bureaucracy — they’re protection for you, your tenants, and your long-term investment. We help you pass them on the first try.
