Legal Basements Requirements

Minimum Ceiling Height
According to Toronto’s building regulations, a legal basement must meet minimum height standards to ensure comfort and safety. For existing finished basements, the required floor-to-ceiling height is at least 6 feet 5 inches (1.95 meters). For new builds or basements undergoing major structural changes, the minimum height increases to 6 feet 11 inches (2.1 meters).
Egress Window Requirements
To meet safety standards, every legal basement in Toronto must have an approved egress window or door. The opening must offer at least 3.8 square feet of clear space, with no single dimension smaller than 15 inches — providing a reliable and accessible emergency exit.

Ventilation Standards
Proper ventilation is essential for maintaining healthy air quality and preventing moisture buildup or mold growth. Basements must meet ventilation requirements either by having windows equal to at least 5% of the total floor area or by incorporating a properly installed ventilation or air conditioning system.
Fire Safety Compliance
Toronto building codes require the use of fire-resistant materials for all partitions, ceilings, and floors in basement construction to enhance household safety. Additionally, smoke detectors and carbon monoxide alarms must be installed on every level of the home, including the basement, and must be interconnected to ensure early warning in the event of an emergency.

Electrical and Plumbing Standards
All plumbing and electrical work must meet the requirements set by the Ontario Building Code and be inspected and approved by the Electrical Safety Authority (ESA). This includes the proper installation of electrical fixtures, ground fault circuit interrupters (GFCI) near water sources, and thorough waterproofing to prevent damage and ensure long-term safety.
Permits and Legal Basement Suites
Before starting any basement construction in the London , obtaining the appropriate building permits is mandatory. If you’re planning to create a legal basement apartment or second suite, additional conditions apply — including compliance with zoning bylaws, proper fire separation, and other safety requirements.
