Why do apartment buildings need scheduled dryer vent cleaning?
Because the risk concentrates and the residents cannot address it. In-unit dryer exhaust in multi-family buildings frequently runs long distances to a roof or shared termination, and residents have no access to any of it. Lint accumulates across the whole run, restricting airflow and creating fire risk in a building where one unit's fire affects everyone. Scheduled property-wide cleaning is the standard control, and insurers increasingly expect to see records of it.
The part residents cannot reach
A resident can clean a lint trap. They cannot clean forty feet of duct running through a chase to a roof cap. In multi-family construction that inaccessible portion is where the restriction actually develops, which makes this a property-level responsibility rather than a resident one.
Shared risers and roof terminations
Where units share exhaust risers, cleaning one unit's branch does not resolve a restricted riser. Where each unit terminates individually at the roof, the terminations are the common failure point, particularly where dampers have stopped working and nesting has occurred. Both need to be in the program scope.
Running the program
Blocks scheduled by building or stack, notice coordinated through management, per-unit airflow verification, and a documented record for each unit. Properties typically run this annually, with high-occupancy and senior living communities sometimes running a shorter cycle.

Common questions
Does our insurer need records of this?
Increasingly, yes. Carriers and fire inspectors commonly ask for evidence of scheduled dryer exhaust maintenance in multi-family buildings. We provide per-unit documentation for exactly that purpose.
What about units where we cannot get access?
They are tracked as incomplete and rescheduled. The final report shows what was completed and what remains, so nothing is quietly counted as done.
Can this be combined with duct cleaning?
Yes, and it is usually more efficient that way. One access event per unit, one resident notice, one mobilization.
