Single Family Dwellings

Building a new single family home is a major investment, and a proper building permit ensures your project meets provincial safety codes, City bylaws and engineering standards. Single family home permits protect occupants, neighbours and the long-term integrity of your property and community.

This page explains when a permit is required, what approvals and inspections are needed, how to apply and what documentation you must provide.


When do you need a permit?

A building permit is required whenever you plan to construct a new single family dwelling on a vacant lot.

In most cases, Development approval must be obtained first from Planning & Design to ensure the lot meets zoning requirements (e.g., setbacks, height, lot size, and permitted uses).

No building permit is issued until zoning review and Development approval are complete.

You can apply online through eApply or in person at City Hall.

Include the following with your application:

  • Site plan, including architectural controls (if applicable)

Things to know before you start

Helpful information to support homeowners and contractors in understanding key considerations, requirements and resources for a successful Single Family Dwelling Development.

Before applying for a building permit:

  • Confirm the property’s zoning district using the City’s Property Information Map.
  • Check the Land Use Bylaw 6300 for permitted uses and minimum requirements (e.g., parcel size, setbacks, building height, etc.).
  • Contact Planning & Design if you’re uncertain about what zoning or development approvals are required.

Development approval ensures your proposed home fits all local regulations before technical review begins.

Your home must meet safety and structural standards in the applicable building codes:

  • Footing & foundation, framing, insulation, vapour barrier, wiring, plumbing, gas and ventilation must comply with applicable codes.
  • Egress windows are required in all bedrooms and must meet minimum size and safety criteria.
  • Tall walls, fire response time and structural member specifications must be addressed in your construction drawings.
  • Attic access, load requirements for heavy point loads (e.g., columns) and special foundation conditions (e.g., piles, ICF) also have specific code requirements.

Professional drawings are often required, especially for structural or engineered.

Building a single family home typically requires several coordinated permits:

Mandatory Permits

  • New Home Warranty / Exemption Number: All newly constructed homes in Alberta must be registered with Alberta Municipal Affairs.
  • Lot Grading Permit: Ensures proper drainage away from the foundation; final grading must be verified by a registered professional (e.g., land surveyor).
  • Building Permit: Includes inspections for Footing & Foundation, Framing, Insulation & Vapour Barrier and Final.

Trade Permits

  • Electrical Permit: May be issued to the homeowner or a contractor, but electrical service must be installed by a licensed electrical contractor. Includes service, rough-in and final inspections.
  • Plumbing Permit: May be issued to the homeowner or contractor; includes rough-in and final inspections. Optional below- and above-grade inspections are available.
  • Gas Permit: Must be issued to a licensed gas installer; includes rough-in and final inspections.
  • Heating & Ventilation (HVAC) Permit: May be issued to homeowner or contractor; includes rough-in and final inspections.

Multiple inspections throughout the build ensure compliance with all applicable safety and construction standards.
