Published
A demolition site is secured overnight with perimeter fencing, machines parked with buckets down and keys removed, any partly standing structure left stable, open excavations protected, and debris kept inside the fenced area. The goal is that nobody can get in and nothing can fall, blow or roll out.
What's needed depends on the stage of the job and how close the site is to neighbours and the street.
Perimeter fencing
Ontario's construction regulation, O. Reg. 213/91, requires that a project be fenced or otherwise protected where needed to keep the public out. On a residential demolition in Vaughan, that usually means temporary panel fencing around the work area, with gates that close and lock at the end of the day.
Leaving the structure stable
If the building isn't fully down at the end of the day, what's left has to be able to stand on its own overnight. Walls aren't left free-standing without support, and the sequence is planned so the day ends at a stable point.
Machines and equipment
At the end of each shift:
- Buckets and attachments are lowered to the ground
- Keys are removed and cabs locked
- Machines are parked away from open edges
- Fuel and small tools are secured
Open excavations
An open basement after a teardown is the biggest overnight hazard. It stays inside the fence, and edges are protected or sloped. If it will be open for a while, talk to your builder about how it's protected until they start.
Debris, dust and the street
Loose debris is kept inside the fenced area, piles are kept stable, and anything light that could blow is loaded or weighed down. The sidewalk and road are cleared at the end of each day. If there's dust, the piles are wetted before the crew leaves.
Signs and contact information
A sign at the gate with the contractor's name and a phone number that's answered means neighbours and passers-by can report a problem at any hour. Ontario's construction regulation also requires certain information to be posted on a project, and many sites post the permit card and emergency contacts at the entrance.
Weather
Weather is the other overnight risk. Before the crew leaves, they check the forecast and plan for it:
- Wind: light debris loaded or tied down, fencing panels braced
- Rain: excavation edges checked and drainage kept clear
- Freeze-thaw: shoring and fencing footings checked the next morning
- Snow: gates and fencing kept clear so the site stays closed
Checking in the morning
Securing the site overnight only works if someone checks it at the start of the next day. The morning check looks at fencing, gates, machines, any standing structure and the excavation, and anything out of place is dealt with before work starts. If something has been disturbed, it's recorded.
Public areas next to the site
The fence protects the site, but the sidewalk and road next to it matter too. At the end of each day, the crew makes sure:
- The sidewalk is clear of debris and open to pedestrians
- Mud and debris tracked onto the road are cleaned up
- Bins and trailers left overnight are placed where the City allows
- Nothing leans on or overhangs the fence into the public area
Longer pauses
If a job stops for more than a night, such as over a long weekend or while waiting on a utility, the site gets a closer check before the crew leaves, and someone visits during the pause.

Frequently asked questions
- Is fencing required on a house demolition?
- Ontario's construction regulation requires the public to be kept out where needed. On most residential demolitions, that means perimeter fencing.
- What if someone gets into the site overnight?
- Call the contractor's number on the site sign. If there's immediate danger, call 911.
- How long does fencing stay up?
- Until the site is safe to open, which is usually after backfill or when the builder takes over.
- Are machines left on site overnight?
- Often, yes, parked safely inside the fence with keys removed.
