Given their unique construction and often below-grade location, it’s crucial to understand the various exit options required by building codes and regulations. This topic explores the specific requirements and considerations for exit options from basements in Ontario. THE ONTARIO BUILDING CODE | EGRESS WINDOWS OR DOORS FOR BEDROOMS 9.9.10.1. Egress windows or doors for Bedrooms (1) Except where a door on the same floor level as the bedroom provides direct access to the exterior, every floor level containing a bedroom in a suite shall be provided with at least one outside window that, (a) is openable from the inside without the use of tools, (b) provides an individual, unobstructed open portion having a minimum area of 0.35 m² with no dimension less than 380 mm, and (c) maintains the required opening described in Clause (b) without the need for additional support. (2) Except for basement areas, the window required in Sentence (1) shall have a maximum sill height of 1 000 mm above the floor. (3) When sliding windows are used, the minimum dimension described in Sentence (1) shall apply to the openable portion of the window. (4) Where the sleeping area within a live/work unit is on a mezzanine with no obstructions more than 1 070 mm above the floor, the window required in Sentence (1) may be provided on the main level of the live/work unit provided the mezzanine is not more than 25% of the area of the live/work unit or 20 m2, whichever is less, and an unobstructed direct path of travel is provided from the mezzanine to this window. (5) Where a window required in Sentence (1) opens into a window well, a clearance of not less than 550 mm shall be provided in front of the window. (6) Where the sash of a window referred to in Sentence (5) swings towards the window well, the operation of the sash shall not reduce the clearance in a manner that would restrict escape in an emergency. (7) Where a protective enclosure is installed over the window well referred to in Sentence (5), such enclosure shall be openable from the inside without the use of keys, tools or special knowledge of the opening mechanism Exit Requirements 1. Egress Windows: One of the primary exit options for basements in Ontario is through egress windows. These windows must meet specific size and accessibility criteria set by the Ontario Building Code (OBC). The window must have a minimum unobstructed open area for escape and must be easily operable from the inside without the use of tools. 2. Window Wells: Egress windows typically require window wells when the window sill is located below grade. Window wells provide a space outside the window for emergency egress and should also meet certain standards for size and accessibility. 3. Exterior Doors: Basements may also have direct access to the exterior through exterior doors. These doors should lead to a safe outdoor area, such as a ground-level patio or yard, free from obstructions. Considerations and Regulations 1. Building Codes: All exit options from basements in Ontario must adhere to the regulations outlined in the Ontario Building Code. These codes specify the dimensions, construction, and accessibility requirements for egress windows, window wells, and exterior doors. 2. Safety and Accessibility: The primary purpose of exit options in basements is to ensure the safety and accessibility of occupants in case of emergencies such as fires or other hazards. It’s essential to consider ease of use and accessibility for all household members. 3. Permit Requirements: Installing or modifying exit options in basements often requires building permits from the local municipality. Compliance with building codes and regulations is typically verified during the permit application process. Common Issues and Solutions 1. Window Well Drainage: Proper drainage around window wells is crucial to prevent water accumulation and potential flooding. Improper drainage can lead to water ingress into the basement. 2. Window Well Covers: Installing secure and properly fitting covers for window wells is essential to prevent accidents and ensure the well remains free from debris and snow accumulation. 3. Emergency Planning: Educating household members about the location and use of basement exits during emergencies is vital. Regularly testing exit options and ensuring they remain unobstructed is recommended. Conclusion Understanding the exit options from basements in Ontario is essential for both homeowners and builders. Compliance with building codes and regulations ensures the safety and accessibility of basement living spaces. By implementing proper exit options and considering safety measures, basements can be transformed into functional and secure areas of the home. Thank you, Amandeep Pathak Permit Canada
