Weeds - FAQ

How bad does the weed problem have to be before a peace officer will come out?

We respond to all calls. A notice may be issued:

  • If the grass is longer than 6 inches (15 cm) tall.
  • If certain types of weeds are growing.
  • If the lack of maintenance on the property has created a fire hazard.

I received a weed notice. Who complained about me?

This information is confidential. We can only tell you whether our investigation is the result of a complaint, or if the peace officer was in the area and initiated the investigation.

What gives inspectors the right to enter a private property?

All weed inspectors are sworn in under the provincial Weed Control Act, and are authorized to enforce pertinent City of Calgary bylaws. These statutes give Animal & Bylaw Services officers the authority to enter on to private land.

I received a notice stating that if I don't mow the yard and laneway, the City will do it and charge me. I'm renting this house. What are my responsibilities?

The City of Calgary automatically bills the property owner for the cost of cleaning-up the weeds, although we do issue a copy of the notice to tenants. We do not get involved in arrangements made between landlords and tenants regarding responsibility for yard maintenance.
