Tenant improvement projects — build-outs, suite renovations, and commercial remodels — generate the same construction dust as ground-up construction, but in a very different setting: usually inside an occupied building, on a compressed timeline, with a tenant waiting to move in the moment the space turns over. TI cleaning has to respect all three realities. This guide covers how it differs from ground-up construction cleaning and how to scope it well.
What Makes TI Cleaning Different
- Occupied surroundings: The suite under construction sits beside suites in business. Dust migration into corridors, elevators, and neighboring spaces is a live issue — and often the building's biggest complaint about a TI project.
- Common-area accountability: Corridors, elevators, and lobbies used for construction access need regular cleaning during the project, and building management will notice when they don't get it.
- Compressed timelines: TI schedules run tight; the final clean often lands in a narrow window between trade completion and tenant move-in, with little slack.
- Move-in standard: The acceptance judge is a tenant taking occupancy — cabinets they'll fill, glass they'll sit beside, floors their furniture lands on. The standard is move-in ready, not just inspection-passed.
Cleaning Through the TI Project
- During construction: Rough cleaning keeps the suite workable and — critically — polices the construction path through the building: walk-off protection, corridor cleaning, and debris routes that respect the occupied floors.
- Final clean: The full post-construction scope, sized to the suite: top-down dust removal, cabinet interiors, glass and tracks, fixture detail, sticker and film removal, and floor care by surface.
- Common-area restoration: Corridors, elevator cabs, and any building areas used for access get detailed back to building standard.
- Touch-up through punch list: Restoration passes behind punch-list corrections, with the last pass immediately before tenant walkthrough.
Dust Control in Occupied Buildings
The complaints that reach building management during TI work are rarely about the suite — they're about the corridor. Practical dust discipline includes maintained containment at the suite entrance, walk-off matting at the construction door, clean debris routes on a schedule that avoids peak building hours, and prompt cleaning of any migration into common areas. The cleaning contractor can't build the containment (that's the GC's scope), but a good one works with it, flags failures, and keeps the building side of the door presentable throughout.
Scoping a TI Clean Well
- State the suite square footage, finish types, and glass/cabinetry scope — TI suites vary enormously per square foot.
- Include common-area cleaning explicitly: which corridors and elevators, restored how often, and to what standard at project end.
- Confirm building rules: work hours, freight elevator booking, badging, and protection requirements.
- Sequence the final clean against the move-in date with touch-up capacity reserved for punch-list closure.
