What are the accessibility requirements for foundation work on a rental property under Ontario's building code?

Foundation work on rental properties in Ontario is governed by the same Ontario Building Code requirements as owner-occupied homes — the OBC does not create a separate accessibility standard for foundation or structural work on residential rental properties. However, there are important intersections between the OBC, the Accessibility for Ontarians with Disabilities Act (AODA), and the Residential Tenancies Act that landlords should understand before starting any foundation or parging project.

What the Ontario Building Code Actually Covers

The OBC Part 9 (Housing and Small Buildings) governs foundation construction, dampproofing, waterproofing, drainage, and masonry for residential buildings up to three storeys. For foundation-specific work — parging, crack repair, exterior waterproofing, weeping tile replacement — the code requirements are the same regardless of whether the property is owner-occupied or rented. You'll need a building permit for structural foundation repairs (crack injection for structural cracks, wall anchors, underpinning, excavation affecting the footing or drainage system), and the work must comply with OBC Section 9.13 for masonry and Section 9.14 for foundation drainage.

AODA accessibility requirements apply differently depending on building type. For small residential rental properties (single-family homes, duplexes, triplexes), AODA obligations are minimal compared to commercial or multi-residential buildings with common areas. If your foundation project involves altering an entrance, walkway, or common area of a larger multi-unit building, you may trigger AODA compliance requirements for accessible paths of travel — but this is a question for your local building department and potentially a lawyer, not a parging contractor.

Practical Implications for Landlords

Where accessibility intersects most directly with foundation work is temporary disruption during construction. If exterior waterproofing or foundation repair requires excavation along a walkway, entrance, or accessible path, Ontario's Building Code and municipal bylaws require safe, accessible temporary access to be maintained for tenants throughout the project. Blocking the only accessible entrance to a unit without providing an equivalent alternative can create liability under the Residential Tenancies Act.

Tenant notification is also a legal obligation, not just courtesy. The Residential Tenancies Act requires landlords to provide reasonable notice before entering a rental unit or disrupting access. Foundation work that affects a tenant's access to their unit, parking, or utilities requires advance written notice — typically 24 hours minimum, though longer notice is appropriate for multi-day projects involving excavation or scaffolding.

What This Means for Your Project

For standard parging, parge coat repair, tuckpointing, or exterior caulking on a rental property, the practical requirements are straightforward: pull a permit if the work is structural, hire a contractor with WSIB coverage and liability insurance, notify tenants in advance, and maintain safe access throughout the project. These are the same steps any responsible landlord should follow regardless of accessibility considerations.

If your project is more complex — exterior waterproofing with excavation, chimney scaffolding, or any work affecting common areas of a multi-unit building — I'd strongly recommend consulting with your local municipal building department about permit requirements and with a legal professional about your obligations under the Residential Tenancies Act and AODA before work begins.

For the masonry and parging side of any rental property foundation project, Toronto Parging can match you with experienced local contractors through the Toronto Construction Network. For questions about AODA compliance, RTA obligations, or building permits specific to your property, your local building department and a licensed paralegal or lawyer are the right resources — those fall outside what a parging matching service can advise on.
