How to Get a Residential Rental License for Your London ARU

A legal ARU is more than a finished space with a tenant. In London, rental licensing, fire safety, egress, permits, and inspections should be planned before occupancy so the unit is defensible for tenants, neighbours, insurers, lenders, and the City.

Decision guide

Check the property before you spend on plans

Use the lot, loan, rent-cap, and servicing screens to decide whether the next step should be design work, a builder conversation, or more research.

  • Check the address
  • Review the loan rules
  • Confirm the rent math
  • Budget the hidden costs

Fire Code Compliance

A legal rental unit needs proper fire separation, safer doors where required, interconnected smoke alarms, carbon monoxide alarms, and a layout that gives tenants a protected way to exit. For basement apartments and garage conversions, fire safety is often one of the largest differences between a finished room and a legal dwelling unit.

  • Review fire separation and door requirements before finishing walls and ceilings.
  • Use interconnected smoke and carbon monoxide alarms where required.
  • Coordinate permit inspections before renting the unit.

Egress And Inspections

Basement suites and detached ARUs need compliant exits and inspections before they are treated as legal rental housing. For basement conversions, egress window sizing and access can drive layout decisions. For detached units, the inspection path also connects to structure, services, insulation, HVAC, and site work. If you are converting an existing shell, review the garage conversion guide as well.

The rental licence is the final mile. The permit, inspection, and safety path should be planned from the first sketch.
