Basement Walkout Entrance Permits & Drawings
Basement entrance permits are required for many new walkout or below-grade entrance projects. Building Permit Group prepares permit drawings, project-specific structural coordination, drainage and waterproofing details, and municipal application support for residential properties throughout Toronto and the GTA.
A Walkout Entrance Changes More Than the Door
Basement entrance permits typically involve more than adding a door. For example, a new walkout may require excavation beside the house, a foundation-wall opening, and an exterior stairwell or landing. In addition, the project may include retaining walls, guards, drainage, grading and waterproofing.
Therefore, Building Permit Group reviews the proposed location, prepares permit drawings, coordinates project-specific structural information when required and supports the municipal permit process.
However, every property is different. The design may be affected by side-yard space, zoning setbacks, lot grading, utilities, easements, trees, existing foundations and the intended use of the basement.
What May Be Included in a Basement Walkout Project?
The exact design depends on the house, foundation, grade, available exterior space and intended basement use.
Foundation Wall Opening
A new exterior door opening through the existing foundation, with structural support designed for the conditions above.
Exterior Stairwell
Concrete, masonry or another approved stair construction with appropriate landings, risers, treads, guards and handrails.
Retaining Walls
Walls designed to retain soil around the excavated stairwell, based on height, loading and site conditions.
Drainage System
Drainage provisions intended to manage water at the bottom of the stairwell without creating moisture problems.
Waterproofing and Flashing
Details at the foundation, door opening and surrounding walls to help protect the basement from water entry.
Grading and Site Coordination
Review of surrounding grade, access, utilities, easements, existing drains and other property-specific constraints.
Basement Entrance Permits: Drawings and Application Information
Submission requirements vary by municipality, property and scope. A basement entrance application commonly requires information such as:
Site Plan
Property lines, house location, proposed entrance, setbacks, exterior dimensions and relevant site conditions.
Existing and Proposed Floor Plans
Basement layout, door location, stairs, landings and the relationship between the new entrance and interior rooms.
Exterior Elevations
Grade, stairwell depth, retaining walls, door, guards, handrails and the relationship to the existing house.
Building Sections
Foundation opening, stair construction, landings, wall heights, waterproofing and below-grade conditions.
Structural Information
Lintel or beam support, foundation details, retaining walls and engineering information where professional design is required.
Drainage and Waterproofing Details
Proposed water management, drainage connection or disposal approach, waterproofing and protection at the new opening.
Guards, Handrails and Stair Details
Stair geometry, landings, guards and handrails documented according to the applicable design requirements.
Municipal Forms and Supporting Documents
Permit forms, designer information and other documents or approvals required for the specific application.
From Property Review to Permit Submission
We organize the design and permit work into clear stages so you understand the project requirements before construction begins.
Project Review
We review the proposed entrance location, basement use and available property information.
Site Assessment
We document dimensions, grade, foundation conditions, access and visible site constraints.
Design Coordination
We develop the stairwell and opening design and coordinate structural information when required.
Permit Drawings
We prepare the plans, elevations, sections and construction details included in our scope.
Application Support
We assist with submission and address municipal comments related to our drawings and services.
Can a Walkout Entrance Work on Your Property?
A basement entrance may be possible, but its location and design must be evaluated against the conditions that apply to your property.
Available Side-Yard Space
The stairwell, excavation and access route must fit within the available exterior space and applicable zoning requirements.
Foundation Conditions
Foundation material, thickness, condition and the structure supported above influence the opening design.
Grade and Drainage
Existing slope, water flow and the proposed stairwell depth affect drainage and waterproofing decisions.
Utilities and Easements
Gas, electrical, water, sewer, telecommunications and registered easements may restrict excavation or entrance placement.
Trees and Exterior Features
Trees, driveways, decks, porches, air-conditioning equipment and neighbouring structures may affect the design.
Intended Basement Use
Requirements may differ when the entrance is associated with a renovation, recreation space or proposed secondary suite.
A Walkout Does Not Automatically Legalize a Basement Suite
A separate exterior entrance may be part of a secondary-suite project, but the dwelling unit must independently satisfy the applicable zoning, Building Code, fire-safety, electrical and other requirements. The entrance permit alone does not establish a legal second unit.
Coordinated Drawings for a Complex Exterior Alteration
We help organize the site, structural, drainage and permit information needed to move your basement entrance project forward.
Property-Specific Review
We assess the proposed location using the available property information and visible site conditions.
Permit Drawing Coordination
We coordinate architectural, site and structural information required for the agreed permit application scope.
Water-Management Focus
We identify drainage, grading and waterproofing considerations that are central to a below-grade entrance.
Municipal Submission Support
We assist with the application process and respond to review comments concerning our submitted drawings.

Basement Entrance Permit Services Across Toronto and the GTA
Municipal zoning, forms, fees and submission procedures vary. Every property and project must be reviewed individually.
Toronto
Includes Etobicoke, North York, Scarborough and East York. Toronto has a dedicated Residential Basement Entrances permit process. Required drawings and supporting information depend on the proposed work and property conditions.
Toronto basement entrance guidance →Mississauga
Mississauga identifies below-grade entrances and basement walkouts as permit work. The proposed location must also be reviewed against the zoning provisions that apply to the property.
Mississauga basement entrance guidance →Brampton
Brampton includes below-grade entrances in its residential permit resources. Zoning, grading, conservation-authority or other approvals may also apply depending on the property and project.
Brampton below-grade entrance guidance →Vaughan
Vaughan requires a building permit for basement walkouts and identifies Development Engineering grading approval as part of the approval process for this type of work.
Vaughan basement walkout guidance →Oakville
Oakville identifies below-grade entrances and basement walkouts as permit work. Walk-up entrances require project-specific construction drawings and details, and additional zoning, heritage, conservation or site-related approvals may apply.
Oakville building permit guidance →Burlington
Burlington identifies a basement walkout addition as work requiring Pre-Building Approval review. Zoning and, where applicable, grading, drainage, forestry and other approvals are coordinated separately from the building-permit review.
