Many tenants in Ontario wonder whether they can alter a rental unit to suit their needs — from painting walls to installing shelves or changing light fixtures. The rules depend on your lease, the type of change, and whether the alteration affects safety or building systems. This guide explains when you generally need landlord permission, what kinds of minor changes are usually allowed, how to document requests, and steps to follow if a landlord refuses. It also covers who is typically responsible for repairs or restoring the unit at the end of your tenancy, and which official forms or applications may apply. Read on for clear, practical advice written for renters navigating alterations in Ontario.
Understanding your rights and the law in Ontario
Ontario renters are protected by the Residential Tenancies Act, 2006[1], and disputes about permission or repairs are heard by the Landlord and Tenant Board[2]. Your lease is the first place to check: some agreements include an alterations clause that limits what a tenant may do. Where the lease is silent or unclear, the law and Board decisions guide whether a change is allowed and who pays for any repair or restoration.
When you need permission
Major alterations that affect structure, electrical, plumbing, or building systems typically require permission and professional work. Examples include removing walls, changing kitchen layouts, or installing hardwired appliances. If a change could affect safety, building code compliance, or other units, always get explicit written permission before starting work. If a landlord denies permission, you can document the refusal and consider next steps with the Landlord and Tenant Board[2].
When small changes are usually allowed
Many minor, reversible changes such as picture hooks, removable shelving, or temporary blinds are often acceptable — but check your lease. Some landlords allow cosmetic changes if you agree to restore the unit when you move out. Questions about routine maintenance, who pays for small repairs, and restoration at the end of tenancy are addressed in provincial guidance and common-practice summaries like Routine Repairs in Rental Units: Tenant and Landlord Responsibilities.
How to ask your landlord — practical steps
Approach requests clearly and respectfully. Written requests create a record and help avoid misunderstandings. If you expect to do work that requires a tradesperson or a permit, say so up front and offer details about timing, who will pay, and how the work will be done.
- Send a written request that describes the change, the proposed timeline and who will pay.
- Attach photos, drawings or product examples to show the planned alteration.
- State who will cover costs and whether you propose to restore the unit at the end of tenancy.
- Keep dated records and proof of delivery when you send the request.
What happens if a landlord refuses or does not reply
If a landlord refuses without a valid reason or fails to respond, gather evidence (copies of your request, photos, receipts) and consider filing an application with the Landlord and Tenant Board. The Board explains the forms and process on its website and lists the relevant application forms[3]. A typical tenant approach is to ask for reconsideration in writing, and if that fails, use the Board process to seek a resolution.
Repairs, restoration and responsibilities
If an alteration causes damage or requires future repairs, responsibility depends on your agreement and whether the change was authorized. If you received written permission that included restoration terms, those terms usually govern whether you must return the unit to its original condition.
