Opening or buying a laundromat in Montreal: check the address before the equipment
Water, drainage, power and dryer-exhaust work can turn an affordable Montreal shop into an expensive laundromat project. Nearby apartments do not show whether households need your machines or already have convenient laundry facilities. Before committing, investigate both the building’s capacity and customers’ existing laundry options. An existing laundry can offer trading records to examine, but its equipment and permissions still need checking when ownership changes.

Demand
Find out what nearby households use now
For your proposed catchment, distinguish four groups of homes:
- homes with in-unit machines
- homes with usable shared laundry
- homes with no facilities
- homes whose laundry availability remains unknown
“Lots of apartments” is too broad a demand test. A building laundry room may already solve the problem you intend to serve.
Field checks in the catchment
Use those observations to decide what to investigate next. Do not use them to turn pedestrians or apartments into forecast customers.
Larger machines need their own demand test
Bulky bedding is a possible reason to visit even when someone has a washer at home. But Montreal’s winter does not, by itself, establish a predictable increase in bulky-load sales.
Before paying for a larger-machine mix, ask prospective customers what they cannot wash conveniently now. When buying a store, request usage records by machine size across the year. Check whether larger washers attract paid loads, whether customers queue for them and whether drying capacity matches those loads. Spare capacity elsewhere in the store does not solve a shortage of the size customers need.
Permits and building
Take the exact address and operating plan to the borough
Montreal’s boroughs have their own zoning by-laws. The City advises checking whether the intended activity is permitted before renting or purchasing premises.2 Do not assume these City of Montreal procedures apply to every municipality in the wider metropolitan area. First establish which authority serves the address.
Describe the actual operation: self-service machines, any wash-and-fold processing, customer collection, proposed hours and alterations. Ask the borough permit counter for written, address-specific guidance.2 Have a lawyer help structure any lease or purchase conditions around satisfactory approvals and technical checks.
Keep the following questions separate:
Permitted activity and occupancy
Starting point: Borough permit counter; City occupancy-permit guidance.
Establish whether the proposed operation is allowed and what occupancy application is needed. The City requires a new permit when the operator or occupied area changes, so do not assume the seller’s permit simply carries over.3
Fit-out and building systems
Starting point: Borough, qualified designers and trades; Québec Construction Code guidance.
Establish which approvals and works the proposed plumbing, electrical, gas and exhaust installation needs. Equipment delivery is not proof that the building is ready.4
Water and sewer connections
Starting point: Borough and a qualified plumbing professional.
Establish whether service or connection changes require permits, and whether the existing supply and drainage can support the equipment.5
Wastewater discharge
Starting point: City wastewater service.
Establish whether this particular operation needs a permit, approval or other measures. The City’s general guidance does not establish a blanket laundromat permit requirement.6
Commercial sign
Starting point: Borough permit counter.
Montreal requires a permit to install, replace or change a commercial sign. Confirm the proposal before fabrication.7
Give the professionals an equipment schedule, not just a proposed machine count. Include the selected models, water-heating arrangement and intended dryer installation. Ask for written findings on capacity, upgrade work, installation costs and any unresolved conditions.
Utilities
Resolve the water meter and utility arrangements in the lease
Montreal requires buildings wholly or partly intended for non-residential use to have a water meter.9
Before signing the lease
For electricity, give Hydro-Québec the proposed load information and request confirmation of the account’s applicable tariff and service requirements.10 For an acquisition, obtain the existing account and billing history. Do not insert a generic electricity allowance into the budget on the assumption that efficient machines make it adequate.
Money
Count paid activity, then follow the cash
For an existing store, reconcile washer payment records with machine activity, prices, refunds and free or corrected washes. Keep each machine size separate. Track dryer receipts separately too, because purchases of drying time are not interchangeable with completed washer cycles.
Check busy periods and downtime, not just average daily activity. An unavailable washer loses the opportunity to serve customers, and a shortage of suitable dryers can disrupt the whole visit. Request repair invoices, fault records and written service terms for the equipment you would own.
The money needs to pass several distinct tests:
Each paid load contributes
Each paid load must contribute toward the remaining bills. Start with its receipts and subtract costs that change with the load, such as attributable water, heating, energy, payment fees and supplies. Use actual equipment and billing information rather than assuming every utility charge varies directly with every cycle.
The store covers its costs
The store must cover its operating costs. The remaining contribution supports rent, staffing, cleaning, maintenance, insurance and other ongoing expenses.
The investment supports more
The investment must support more than the store. Allow for the owner’s work, actual financing payments, tax cash payments and equipment replacement funding. Operating surplus is not automatically cash available to take home.
For a new build, obtain equipment and installation quotes in Canadian dollars (CAD), alongside written utility and premises findings. Keep untested sales assumptions clearly separate from quoted costs. Obtain financing terms for the actual borrower and project, including when repayments begin if opening is delayed. A lender’s advertised product is not an approved offer.11
Operations
French service and unattended operation both need planning
Québec’s French-language obligations apply to businesses operating in the province. Public and commercial display must be in French, and additional languages are subject to the applicable conditions.1213 Treat French customer information and service as an operating requirement, not merely a preference for bilingual branding.
Review machine instructions, payment prompts, refund notices and the proposed business sign against current Québec and OQLF guidance. Check the actual name and wording before printing.13 Municipal sign permission and provincial language compliance are separate checks.
Coverage plan for an unattended floor
Remote payment tools do not replace that coverage plan.
Wash-and-fold adds intake, order tracking, processing, folding and collection work. Assess it separately from self-service. Its receipts must support handling labour and supplies as well as machine use. It can also compete with self-service customers for equipment during busy periods.
Next step
Make the next commitment conditional on the missing evidence
Buying an existing laundromat
Before buying, compare the seller’s sales claims with payment reports, bank records and tax filings. Inspect utility bills, the lease, permit history, repair records and equipment ownership. Ask the seller to describe the work they perform, then price or assign the work you will inherit.
Building a new store
Before building, establish a plausible customer need, obtain borough guidance and complete the technical inspection before placing irreversible equipment orders.
The useful Montreal decision is not whether laundromats can work in the city. It is whether this address, this machine mix and this coverage plan can serve a verified need while leaving enough cash to pay for the work and sustain the equipment.
Summary
Key takeaways
- Count which nearby homes lack convenient laundry. A large number of apartments is not enough evidence of demand.
- Ask the borough for written guidance on the exact address before renting or buying. A seller’s occupancy permit does not simply carry over.
- A water meter confirms neither supply capacity nor who pays. Settle utilities in the lease in writing.
- Reconcile payments with machine activity by machine size, and keep washer and dryer receipts separate.
- French customer information and an incident coverage plan are operating requirements, including for an unattended store.
- Make the next commitment conditional on the evidence that is still missing.
