Railing Height and Code Requirements in Alberta: What Homeowners Need to Know

Summary:Alberta has clear building code standards for railing height, strength, and spacing. These rules help keep decks, balconies, and stairways safe. This guide explains the main requirements so homeowners can plan their railing project confidently.

Understanding Alberta’s Railing Codes

Alberta follows the National Building Code of Canada along with provincial guidelines. These standards ensure railings can handle real world use and prevent falls.

Minimum Railing Heights

For decks, balconies, and raised platforms:

•If the walking surface is more than 24 inches above the ground, a guardrail is required.

•Railings must be at least 42 inches high for most elevated surfaces.

For stairs:

•Handrails on stairways must be between 34 and 38 inches in height, measured vertically from the stair tread.

•Guardrails alongside open stairways must also meet the 42 inch minimum unless the building type allows exceptions.

Spacing and Safety Requirements

•Openings in a guardrail cannot allow a 4 inch sphere to pass through. This prevents small children from slipping through.

•Railings must be built to resist horizontal force so they remain stable during use.

•Glass used in railings must be tempered or laminated for safety.

Why These Rules Matter

Clear standards help reduce accidents and give homeowners peace of mind. Meeting code also protects you during resale, insurance claims, and home inspections. Even small deviations can lead to costly fixes later.

Choosing a Code Compliant Railing

Whether you prefer glass, aluminum, or picket railings, reputable installers will design your system to meet Alberta’s guidelines. A professional can confirm height, spacing, and load requirements for your specific home.
