Basement Suite Rental Income in Winnipeg: Rules, Rent and Payback

A basement suite can bring in rent every month, but only once it’s legal, and only if the numbers work for your house. That comes down to three things: whether the City allows a suite on your lot, what the building code asks of the space, and what a tenant will realistically pay.

This guide uses the City of Winnipeg’s secondary suite pages and forms, the 2020 National Building Code as Manitoba adopted it, and CMHC’s October 2025 rental survey, with the date we checked each one listed under Sources. It’s general information, not legal, tax or financial advice, and the City’s documents and staff govern for your property.

When can you legally rent out a basement suite in Winnipeg?

When zoning allows it, the permits are in place and the work has passed final inspection. The City says attached suites, such as a basement suite, may be permitted in every zoning district that allows single-family homes, and only one suite, attached or detached, is allowed per lot.

Before construction, homeowners need a development permit and a building permit, and the City requires separate electrical and plumbing permits. Its housing inspections page says the final inspection confirms that all work under all permits is complete and the project is ready for occupancy or use. Plan a tenant’s move-in date after that inspection, not before.

If a suite doesn’t meet the Zoning By-law’s use-specific standards, the City’s April 2026 form says a conditional use application is required. The fee to establish an attached suite that way is $274 plus GST ($287.70). The process includes public notices and a hearing; the City says its length depends on how complex and complete the application is.

The zoning districts, size limits, parking and the rules for garden and garage suites are covered in our guide to secondary suite rules in Winnipeg. The Zoning By-law was amended in June 2025 and the City’s page doesn’t say whether it reflects that, so confirm the rules for your address with the City before you design.

Can you rent out a suite that was built without permits?

Get it approved first. If an existing attached suite doesn’t meet the use-specific standards, the City’s form calls for a conditional use application to maintain it. The fee is $660 plus GST ($693.00).

If the conditional use is rejected on appeal, the form says no building or development permit can be issued for the work, and the same conditional use can’t be applied for again within one year of the Appeal Order.

Permit Amnesty may not help here. The City’s program is for work at a homeowner’s primary residence, and its page lists rental properties as not eligible, so ask the City how that applies to a house with a rented suite. Our guide to checking a home’s permit history shows how to find out what was permitted.

What ceiling height does a basement suite need?

At least 1.95 m (about 6 ft. 5 in.), with at least 1.85 m (about 6 ft. 1 in.) of clear height under beams and ducts. Those are the secondary suite minimums in the 2020 National Building Code, which Manitoba adopted with its own amendments on January 1, 2024.

Where the ceilings meet that minimum, doorways inside the suite can be sized for doors 1,890 mm (about 6 ft. 2 in.) high. The City’s guide for ordinary basement development uses 2.1 m (6 ft. 11 in.) for finished rooms, so ask its plan examiners which figure applies before you plan around a low ceiling.

What are the egress window rules for a suite bedroom?

Unless the suite is sprinklered, each bedroom needs an outside window or exterior door that opens from the inside without keys, tools or special knowledge. A bedroom window must:

• give an unobstructed opening of at least 0.35 m² (3.77 sq. ft.), with no dimension under 380 mm (15 in.)
• stay open on its own in an emergency, without extra support
• have at least 760 mm (2 ft. 6 in.) of clear space in front of it where it opens into a window well

The City’s basement guide uses the same minimums for any basement bedroom. A new or enlarged opening in a foundation wall needs drawings stamped by an engineer, and our guide to basement development permits covers the rest of the City’s checklist.

What fire separation, alarms and sound control does a suite need?

A smoke-tight drywall barrier between the two units, smoke alarms interconnected across both, and a sound-rated separation. A house with a suite gets lighter rules than an apartment building; the table sets out the main requirements in Part 9 of the code, with the article numbers to show your designer or the City.

Summary of Part 9 of the National Building Code of Canada 2020, which Manitoba adopted with amendments (Manitoba Regulation 78/2023); the carbon monoxide row includes Manitoba’s amendment to Article 9.32.3.9. The code and the City’s plan examiners govern.

Plan the entrance with the exits. The City describes an attached suite as having a separate entrance, and each household must reach its own services, such as the panel, without passing through the other unit.

In a house with a suite, the units can share an exit stair without each needing a second, separate exit. The exception: an upper unit whose door opens onto an exterior passageway more than 1.5 m above the ground, served by one stair and with a floor rated under 45 minutes, needs a second exit (Article 9.9.9.3.).

What can a basement suite rent for in Winnipeg?

CMHC doesn’t publish basement-suite rents for Winnipeg, so the closest benchmark is its Rental Market Survey. Run every October, it covers privately initiated rental buildings with at least three units, so its figures show what Winnipeg tenants pay for an apartment, not for a suite.

Source: CMHC Rental Market Survey, Winnipeg data tables 1.1.1, 1.1.2 and 1.1.9 (October 2025). Vacant units show what landlords were asking for units that were empty at the time of the survey.

Vacancy rose over the year, and rent growth slowed. The overall vacancy rate went from 1.7% to 2.8%, and CMHC reports that conditions softened across the Winnipeg area in 2025, with vacancy rising in suburban neighbourhoods.

The average one-bedroom rent was $1,232, up from $1,179 in October 2024, but those averages cover different sets of buildings. For buildings surveyed in both years, CMHC estimates one-bedroom rents rose about 1.8%, and it says increases for existing tenants stayed below Manitoba’s rent increase guideline of 1.7%.

A suite’s own rent depends on its size, light, ceiling height, entrance and what’s included, such as utilities or parking. Compare current listings for similar suites near you, then use the figure you expect in the calculator below.

How do you work out a basement suite’s payback?

With your own numbers. Use the total from a written quote for the suite and a rent you’ve checked against local listings. Our instant price guide shows basement-development ranges, not suite prices. The calculator works out three figures:

• Gross yield: a year of rent divided by the build cost.
• Net monthly income: the rent, less vacancy and the monthly costs you’ll pay, such as utilities, insurance and maintenance.
• Simple payback: the build cost divided by a year of net income.

As an example, take CMHC’s one-bedroom average of $1,232 a month and the 2.8% vacancy rate for all units. That’s about $14,370 of rent a year, so each $10,000 of build cost takes about eight months of rent to recover, before any costs you pay.

Before you commit, check the numbers with your lender and a tax professional.

How can you pay for a suite, and what help exists?

The main federal tool is insured refinancing. Since January 15, 2025, lenders can offer CMHC-insured refinancing to homeowners adding a secondary suite, on the terms in the table. The two suite loan programs many sites still mention aren’t available.

Sources: Department of Finance Canada (October 8, 2024), CMHC refinance fact sheet (August 2025), Budget 2025 Annex 3, and an archived copy of the Province of Manitoba’s program page (August 13, 2025).

Rent from a suite is also reported for income tax. The Canada Revenue Agency says form T776, Statement of Real Estate Rentals, is used by rental property owners to report rental income and expenses. Ask a tax professional how a suite affects your return before you rely on a payback figure.

Building the suite so a senior, or an adult eligible for the disability tax credit, can live with a relative? The federal Multigenerational Home Renovation Tax Credit may apply; see our guides to Manitoba renovation tax credits and rebates and home renovation financing in Canada.

When do you need a designer or engineer for a suite?

Most suites start on paper. The City’s basement permit form asks for a fully dimensioned floor plan showing each room’s use, every door and window, and the electrical and plumbing layout. Some parts of a suite need a professional:

• An engineer’s stamp on drawings for any window added or enlarged in a foundation wall.
• Engineered drawings for major structural work, such as changing beams or teleposts.
• For a garden or garage suite, a water and sewer site servicing plan prepared by a Manitoba land surveyor or professional civil engineer.

The heating layout is worth settling early too. The code’s rules on separate ducts and controls decide where ducts run, and that affects the ceiling heights you can keep.

Apart from radiant heating, a heating or air-conditioning system that serves both units has to meet Part 6 of the code rather than the house rules in Part 9 (Article 9.33.1.1.), so ask the City what it needs to see for your layout.
