Demolition Adjacent to Occupied Buildings

Demolition next to occupied buildings requires additional controls to protect residents and occupants.
Dust, noise, vibration, and falling debris from demolition directly affect people in adjacent properties.
Party walls shared with occupied buildings must be assessed for stability before demolition starts.
Structural monitoring of the adjacent building using tell-tales and survey points is typically required.
Hoarding and debris netting must prevent material falling or projecting towards the occupied building.
Noise and vibration limits may be imposed by the local authority under environmental health powers.
Asbestos surveys and removal must be completed before demolition to prevent fibre exposure to neighbours.
CDM 2015 and the Environmental Protection Act 1990 both apply to demolition near occupied premises.
A community liaison plan must communicate the works to affected residents before demolition begins.
Working hours may be restricted to reduce the impact on residents during unsociable hours.

Public safety	Debris, dust, and structural failure from demolition can injure or kill building occupants.
Structural risk	Removing shared structures can destabilise the adjacent occupied building.
Nuisance complaints	Excessive noise, dust, and vibration trigger enforcement action and project delays.
Legal compliance	CDM, environmental protection, and building regulations all impose duties near occupied premises.

Do

Don't

Assess the structural impact on adjacent occupied buildings before starting demolition.
Install structural monitoring on the adjacent building and review readings regularly.
Erect hoarding and debris netting to protect the occupied building from falling material.
Complete asbestos removal before demolition to prevent fibre exposure to neighbours.
Communicate the demolition programme and expected impacts to affected residents.
Comply with noise and vibration limits imposed by the local authority.
Use water suppression to control dust drifting towards occupied buildings.
Monitor for cracks, movement, or distress in the adjacent building during works.
Restrict working hours as required to minimise disruption to residents.
Maintain a complaints log and respond to concerns from neighbours promptly.

DON'T start demolition without assessing the impact on adjacent occupied buildings.
DON'T demolish party walls or shared structures without specialist engineering advice.
DON'T allow demolition debris to fall or project towards the occupied building.
DON'T demolish without completing the asbestos survey and removal first.
DON'T exceed noise or vibration limits set by the local authority.
DON'T ignore complaints from residents — investigate and act on them.
DON'T skip structural monitoring of the adjacent building during demolition.
DON'T work outside agreed hours without prior approval and notification.
DON'T allow dust plumes to drift onto occupied properties.
DON'T remove hoarding or protection before the demolition phase is fully complete.
