Renovating an apartment you rent out, or a unit in a duplex, triplex or larger plex, is a renovation with a third party involved: the tenant. The carpentry, plumbing and finishes are the same as in any home, but the schedule, the notices you give and whether anyone has to move out are governed by provincial tenancy law, and getting them wrong can halt the work or cost more than the renovation itself.

Owners take on apartment renovations for different reasons: to refresh a unit between tenants, to upgrade a kitchen or bathroom while someone still lives there, to fix aging systems across a building, or to add a legal unit to a house or plex. Each path has its own rules in Ontario and Quebec, and each changes how a contractor plans the job, protects occupied spaces and phases the work.

This page covers notices and access for work in occupied units, what happens when tenants must leave, permits and fire separations between units, and finishes that stand up to rental use. For renovating a unit you own in a condominium, see our condo renovations page.

Types of apartment renovations: turnovers, occupied-unit upgrades, building systems and new units

  • Turnover renovations happen between tenancies, when a vacant unit can be repainted, refloored or given a new kitchen or bathroom without notices or relocation.
  • Upgrades in an occupied unit, such as a new bathroom or kitchen, go ahead while the tenant stays, under notice and access rules that limit when the crew can be there.
  • Building-wide work on roofs, windows, plumbing risers, electrical service or heating affects several households at once and has to be scheduled around each of them.
  • Adding a unit to a house or plex, or combining or dividing existing ones, changes how the building is used and brings zoning, permit and fire-safety requirements.

Renovating an occupied rental unit: notice, access and work hours in Ontario and Quebec

In Ontario, the Landlord and Tenant Board's guideline on entry says a landlord may enter a unit to carry out repairs or work after giving written notice at least 24 hours in advance that states the reason, the date and a time of entry between 8 a.m. and 8 p.m.

In Quebec, the Tribunal administratif du logement separates routine access from major work. For inspections and ordinary repairs, the lessor gives 24 hours' notice, verbally or in writing, repairs are done between 7 a.m. and 7 p.m., and urgent repairs such as a major plumbing leak can go ahead immediately. Substantial improvements or repairs, such as renovating a bathroom or kitchen, are major work: the lessor must give 10 days' notice if the tenant doesn't have to leave or leaves for no more than a week, and three months' notice if the dwelling must be vacated for longer. The notice states the type of work, the start date and estimated duration, the conditions affecting the tenant's use of the dwelling and, where relevant, how long they would be out and the compensation offered.

  • A Quebec tenant has 10 days after receiving a major-work notice to ask the Tribunal to change conditions they consider abusive, and the work is suspended once either party applies, unless the Tribunal decides otherwise.
  • Compensation for a temporary move covers moving and storage costs, extra rent paid and other reasonable expenses, and is payable when the tenant vacates.
  • During the lease, the lessor can't raise the rent or change other lease conditions because of the work.
  • Contractors working in an occupied unit should protect floors and belongings, contain dust, and restore water, heat and a usable bathroom at the end of each day wherever they can.

When tenants must move out for renovations in Ontario: N13 notices, compensation and the right to return

An Ontario landlord can end a tenancy for repairs or renovations only when the work is so extensive that it requires a building permit and vacant possession of the unit. According to the Landlord and Tenant Board's guideline, this is done with an N13 notice whose termination date is at least 120 days after it is given. A tenant who informs the landlord in writing that they intend to move back can return when the work is finished, at the same rent as before. In a building with five or more units, the landlord owes three months' rent to a tenant who doesn't return, or the rent for the lesser of three months and the repair period to one who does; with fewer than five units, it is one month's rent, or the lesser of one month's rent and the repair period.

  • In Toronto, the Rental Renovation Licence Bylaw requires a landlord who issues an N13 for work needing vacant possession to apply for a licence within 7 days, with the building permits and a qualified person's report confirming that vacant possession is required.
  • Toronto licence holders must also offer the tenant either temporary comparable housing or rent-gap payments, plus a moving allowance; enforcement began on July 31, 2025, for N13 notices issued from that date.
  • A tenant who believes an N13 was given in bad faith can apply to the Board, so the scope, drawings and permits should be real before any notice goes out.

Quebec: temporary relocation for major work and the moratorium on evictions to subdivide or enlarge

Quebec handles long renovations differently from Ontario. For major work, the lessor asks the tenant to vacate temporarily rather than ending the lease. The tenant has 10 days after receiving the notice to say whether they agree, no answer counts as a refusal, and after a refusal the lessor can apply to the Tribunal within 10 days to rule on whether vacating is advisable and on what conditions. Ending a lease in order to subdivide a dwelling, enlarge it substantially or change its use is a separate process, and the Tribunal explains that a law assented to on June 6, 2024 prohibits evicting a tenant for those purposes for three years.

Permits, fire separations and legal secondary units when renovating a plex

Work inside an existing unit follows the usual permit triggers, but changing the number of units is a change of use. Toronto's permit guidance, for example, says turning a single-unit house into a multi-unit house needs a building permit even when no construction is proposed, as does finishing a basement to add a second suite. Ontario's guidance on second units advises speaking first with the municipal planning and building departments, since parking, exit, servicing or unit-size rules in local bylaws can rule a unit out.

Between units, the building code calls for fire separations: rated wall and ceiling assemblies, with sealed penetrations and suitable doors, that slow fire and smoke from spreading from one home to the next. Ontario's second-unit guide requires them between the units and between each unit and common areas, and allows a shared exit only if the exit area is itself fire-separated. A renovation that opens a ceiling for pot lights, ducts or pipes can breach that separation, so the contractor must restore it with materials that match the rated assembly.

  • Ontario's guide calls for smoke alarms on every level of the house and in each bedroom of the second unit.
  • Carbon monoxide alarms are required where the house has a furnace burning natural gas, propane or a similar fuel.
  • Electrical work for a new unit needs its own electrical permit and an inspection by the Electrical Safety Authority.

Durable, repairable finishes for rental apartment renovations

  • Choose flooring that tolerates wear and water and can be repaired one section at a time, rather than a finish that has to be replaced wall to wall after one damaged area.
  • Standardize paint colours, fixtures and hardware across units, so touch-ups and replacements at turnover are quick.
  • Have the plumber put accessible shut-off valves in each unit, so a leak can be stopped without cutting water to the whole building.
  • In older plexes, follow Health Canada's advice to have suspect materials tested for asbestos before renovating, and treat paint in buildings from before 1960 as probably lead-based.

Apartment Renovations: frequently asked questions

Can a landlord evict a tenant to renovate in Ontario?

Only for repairs or renovations so extensive that they need a building permit and vacant possession, with an N13 notice giving at least 120 days. The tenant can return at the same rent by telling the landlord in writing, and compensation is owed. In Toronto, a Rental Renovation Licence is also required.

Does a tenant in Quebec have to leave during major work?

Only if they agree or the Tribunal administratif du logement decides it's advisable. The lessor's notice must state how long the tenant would be out and the compensation offered, and the tenant has 10 days to answer; not answering counts as a refusal.

How much notice must a landlord give before contractors enter a rental unit?

In Ontario, at least 24 hours' written notice, with entry between 8 a.m. and 8 p.m. In Quebec, 24 hours' notice, verbal or written, with repairs done between 7 a.m. and 7 p.m., though urgent repairs can be done immediately.

Can the rent go up after an apartment renovation?

In Ontario, a tenant who returns after an N13 renovation pays the same rent as before the tenancy ended. In Quebec, the lessor can't raise the rent during the lease because of major work. Increases at renewal follow each province's own rules.

Do I need a permit to add an apartment to my house or duplex?

Yes. Adding a unit changes the building's use and needs a building permit, and zoning must allow the unit. Expect requirements for fire separations, exits, alarms and a separate electrical permit, so talk to your municipality's planning department before drawings are made.

  • Size and scope of the project
  • Structural changes, such as moving or removing walls
  • Plumbing, electrical and HVAC work involved
  • Finishes and materials chosen
  • Design, drawings and permits
  • Condition of the existing house once it's opened up

How to compare renovation contractors before you hire

  • Look for a contractor who has finished projects similar in size and type to yours, and ask to see them.
  • Get a written contract with the scope, the payment schedule, the timeline and how changes will be priced.
  • Ask who will manage the job day to day and how often you'll get updates.
  • Check that they carry liability insurance and workers' compensation coverage, and that their trades are licensed where required.
  • Compare quotes on the same scope, and ask what each one leaves out.
  • For structural changes, make sure an engineer or designer is involved where needed.

Questions to ask renovation contractors before you hire

  • Who will pull the permits, and who will be there for inspections?
  • Which parts of the job will you do yourselves, and which will go to subcontractors?
  • How do you handle change orders and unexpected problems once walls are open?
  • What is the payment schedule, and what is each payment tied to?
  • Can you show me proof of liability insurance and workers' compensation coverage?
  • What warranty do you offer on your workmanship, and is it in writing?
  • Can I speak with a few of your recent clients?

Apartment renovation permits and local rules

Some apartment renovation work needs a permit or has to meet local bylaws. Rules vary by municipality, so ask your pro whether a permit is needed and who will apply for it — and check with your city or town if you’re unsure.
