Table Of Contents

TL;DR

St. Catharines requires all Airbnb and short-term rental (STR) operators to hold a Short-Term Rental Licence under By-law 2021-67. Only properties in approved zones and owned by residents can operate legally. Hosts must pay a 4 % Municipal Accommodation Tax (MAT), maintain $2 million liability insurance, and follow noise, parking, and safety standards. Unlicensed hosts may face fines of up to $100,000 per offence.

Introduction

With its historic downtown, close proximity to Niagara Falls, and Port Dalhousie waterfront, St. Catharines has become a growing hub for short-term rentals. But to protect housing availability and maintain community balance, the city introduced By-law 2021-67, setting out strict conditions for Airbnb and STR operators.

If you rent your property for fewer than 30 days at a time, you must obtain a Short-Term Rental Licence for property in St. Catharines. The rules cover zoning, safety, occupancy, and the 4 % Municipal Accommodation Tax (MAT) that applies to every booking.

This updated 2025 guide explains everything St. Catharines hosts need to stay compliant — from licensing steps and inspection requirements to noise, insurance, and tax obligations — plus how FullHome helps manage compliance while maximizing rental performance.

St. Catharines STR Licensing & Eligibility Requirements

The City of St. Catharines regulates all short-term rentals under By-law No. 2021-67, introduced to create safer, fairer operations across residential and tourist areas. If you plan to list your property on Airbnb, Vrbo, or Booking.com, you must obtain a valid Short-Term Rental Licence.

🔹 Who Needs a Licence

  • Anyone renting a property or unit for 28 days or less.

  • Applies to all platforms and private short-term leases.

  • Both homeowners and designated property managers can apply, provided the property qualifies.

🔹 Licence Type & Validity

  • Each STR property requires its own licence, valid for one year.

  • Licences are non-transferable between properties or owners.

  • Renewal is required annually before expiry.

🔹 Application Process

  1. Complete the STR Licence Application on the City of St. Catharines portal.

  2. Submit supporting documents:

    • Proof of property ownership or consent from the owner.

    • Proof of liability insurance (minimum $2 million coverage).

    • Floor plan, site plan, and parking details.

    • Fire inspection certificate and safety plan.

  3. Pay the annual fee — $500 for initial applications, $250 for renewals.

  4. Schedule and pass inspections for fire, building, and by-law compliance.

🔹 Display & Advertising

  • The licence number must appear on every online listing and inside the rental unit.

  • Hosts are responsible for ensuring that any third-party managers also follow this requirement.

💡 Tip: The city performs random audits — keeping digital and printed proof of compliance helps avoid interruptions in listing approval.

St. Catharines STR Zoning Rules & Property Restrictions

Zoning is one of the most important factors determining whether your property can legally operate as an STR in St. Catharines.

🔹 Approved Zones

  • STRs are allowed in Residential (R1–R4) and Commercial (C1–C2) zones that permit lodging or accommodation use.

  • Properties in Heritage or environmentally sensitive zones may require additional municipal review.

  • Check your property’s zoning at St. Catharines GIS Map Portal before applying.

🔹 Principal Residence Requirement

  • STRs are only allowed in the host’s principal residence.

  • You must live in the property most of the year — investment or vacant homes cannot be licensed.

  • Proof of residency (driver’s licence, utility bill, or municipal tax record) is required during application.

🔹 Condo & HOA Restrictions

  • Many condos and townhouse developments have internal bylaws prohibiting STR activity.

  • The city licence does not override condominium declarations — hosts must obtain written permission if applicable.

🔹 Port Dalhousie & Tourist Zones

  • STRs in Port Dalhousie and waterfront districts must meet parking and density limits to protect residential character.

  • The city limits the number of STRs per street block in high-demand areas.

💡 Pro Insight: The City uses Airbnb’s data-sharing agreement to verify unlicensed listings, particularly in Port Dalhousie and downtown St. Paul Street — zoning violations are among the most common causes of fines.

St. Catharines STR Operational Rules & Safety Standards

Once licensed, every short-term rental in St. Catharines must comply with ongoing safety, property, and guest behaviour rules outlined in By-law 2021-67 and related municipal codes.

🔹 Fire & Building Safety

  • The following are mandatory:

    • Working smoke alarms on every level and in each bedroom.

    • Carbon monoxide detectors near sleeping areas.

    • A fire extinguisher on each floor.

    • A clearly posted evacuation plan and emergency contact numbers.

  • The City conducts inspections prior to licence approval and periodically for renewals or complaints.

🔹 Occupancy Limits

  • Maximum two guests per bedroom, up to a total of eight guests per dwelling.

  • Hosts must list occupancy limits in the online listing and enforce them during stays.

🔹 Parking Requirements

  • Minimum one on-site parking space per guest room.

  • Vehicles must not block sidewalks, driveways, or neighbouring properties.

🔹 Noise & Nuisance Rules

  • The Noise By-law (89-2000) restricts excessive sound between 11:00 PM and 7:00 AM.

  • Hosts are responsible for guest conduct — repeated noise violations can lead to licence suspension or revocation.

🔹 Maintenance & Waste

  • STRs must meet general Property Standards By-law (2020-89).

  • Waste can only be placed curbside on collection days.

  • The property exterior must remain clean, well-lit, and hazard-free.
