Rental licensing in London, Ontario

Last reviewed October 30, 2026

London is one of several Ontario cities that license residential rental units. If you own a small rental property in London, from a single rented house to a fourplex, there's a good chance you need a licence. Here's an overview of how it works. Always confirm the current requirements with the City.

What the by-law covers

The City's Residential Rental Unit Licensing (RRUL) By-law sets standards for rental units. According to the City, its purpose is to protect the health and safety of people living in rental housing and to maintain the amenity, character and stability of residential areas. It generally applies to rental buildings with four or fewer units. Larger apartment buildings are regulated differently.

Do you need a licence?

If you rent out a house, a unit in a duplex, triplex or fourplex, or an additional residential unit, you likely need a licence for each rental unit. Exemptions and specific definitions apply, such as certain owner-occupied situations, so check the by-law and the City's guidance for your situation. If in doubt, contact the City's licensing office before you rent the unit out.

How to apply

Based on the City's published process, an application typically includes:

1. A completed licence application form
2. A floor plan showing the location of all rooms, windows and entrances/exits
3. A self-certification checklist for each unit
4. Payment of the applicable fees

Applications have been accepted by email to the City's licensing office. See the City's residential rental unit licence page for current forms and fees.

Inspections

The City conducts inspections in partnership with London Fire Prevention. Inspectors look at property standards and fire safety: smoke and carbon monoxide alarms, egress, fire separations where required, electrical hazards, and the general condition of the unit. Fix deficiencies within the timelines given.

Fees and penalties

Licence fees are set by the City and renewed annually. Fees and penalties change, so check the City's current fee schedule. Penalties for operating without a licence can be substantial: the City states that the maximum fine on a first conviction under the by-law is $25,000 for a person and $50,000 for a corporation, and the maximum doubles for later convictions (source: City of London).

Licensing and tenancies

Licensing is a municipal requirement. It sits alongside, not instead of, your obligations under the Residential Tenancies Act. Even with a licence, you must use the standard form of lease, follow the rules on deposits and rent increases, maintain the unit, and follow the LTB process for any eviction. See landlord basics.

Short-term rentals are separate

Short-term accommodations (stays under 30 days, such as Airbnb) are licensed under a different City by-law, with a principal-residence requirement. See short-term rentals.

Buying a licensed property

Licences are generally tied to the owner, so a new owner usually needs to apply in their own name. When buying an existing rental:

• Ask the seller for the current licence and recent inspection reports.
• Confirm the number of units the City recognises.
• Ask about outstanding orders or work orders. Your lawyer can search for some of these.
• Budget time for your own application after closing.

A licensing checklist for new landlords

• Confirm the unit is legal (permits, zoning).
• Install and test smoke and CO alarms in every unit.
• Check bedroom egress windows meet requirements.
• Prepare an accurate floor plan.
• Complete the self-certification checklist honestly.
• Apply before your first tenant moves in.
• Diarise the annual renewal.
