Post-construction cleaning for a ground-up new build and a suite-level tenant improvement look similar on a price sheet — but they're very different projects. New builds generate far more debris across larger footprints. Tenant improvements are smaller but carry unique challenges: occupied adjacent spaces, phased handovers, and strict dust control requirements. Understanding how scope, sequencing, and pricing of post-construction cleaning services changes based on project type helps both owners and GCs scope accurately and avoid surprises.
New Build Post-Construction Cleaning
A ground-up new build is the larger, messier, but more straightforward project type. The building is unoccupied throughout construction, access is unrestricted, and the three phases of cleaning follow a predictable sequence.
Characteristic features:
- Higher total dust volume (drywall sanding, concrete cutting, grinding)
- Larger surface area to clean (often tens of thousands of square feet)
- Multiple levels requiring elevator and lift access
- Exterior glass and fixture cleaning included
- HVAC and ductwork usually accessible for filter changes and cleaning
- More labor per square foot (roughly 30–60 minutes per 1,000 sq ft of final cleaning)
- Scheduling relative to other trades (casework, painting, flooring) is critical
New build cleaning vendors need to bring significant equipment: multiple HEPA vacuums, ride-on auto-scrubbers, pressure washers for exteriors, elevated platforms, and large crews that can work parallel zones.
Tenant Improvement (TI) Cleaning
Tenant improvement projects — remodeling a space within an existing occupied building — have entirely different constraints:
- Adjacent occupied spaces that must remain unaffected by the work
- Shared HVAC systems that can carry dust to neighboring suites
- Shared corridors, restrooms, and loading docks with occupants
- Strict hours-of-work restrictions (often after-hours or weekend only)
- Limited debris staging — no on-site dumpsters in many buildings
- Elevator coordination with building management
- Noise and disruption limits from the building rules
The cleaning itself may be a smaller scope (often 2,000–20,000 sq ft) — but the coordination complexity is higher. TI cleaning vendors need to be comfortable working in buildings with other tenants and following building-specific protocols.
Dust Control Is the Big Difference
In a new build, some dust escape during cleaning is acceptable — no one is downwind. In a TI, dust escape is immediately a problem. TI cleaning requires:
- HEPA filtration on every vacuum (not just the main ones)
- Sealed work zones during active cleaning to prevent dust migration to adjacent spaces
- Plastic sheeting at work zone boundaries — typically installed by the GC but respected by the cleaning crew
- Coordinated HVAC management — the TI suite may have isolated air handling, or the shared system may need to be shut down during dusty operations
- Walk-off mats and shoe covers to prevent tracking dust into occupied corridors
- Careful debris removal — bagged and sealed rather than loaded onto open carts
Building management will often require documented dust control protocols before allowing work to proceed.
Scheduling and Phasing Differences
New build cleaning follows the standard three-phase timeline:
- Rough cleaning during construction
- Final cleaning after substantial completion
- Turnover cleaning before occupancy
TI cleaning often compresses this:
- The project is small enough that rough and final may happen in the same session
- Work is frequently done in off-hours (after business hours, weekends)
- Phased moves may require multiple turnover cleans as the tenant takes occupancy of zones incrementally
- Overnight turnaround is common: work ends at 10 PM, space is ready for the tenant by 8 AM
TI work rewards vendors who can respond quickly and work in tight windows. New build work rewards vendors who can scale crews and run sustained multi-day operations.
How Pricing Differs
New build pricing is typically quoted per-square-foot for final cleaning (with rough and turnover quoted separately). Per-sf pricing drops with scale — a 50,000 sq ft project prices lower per foot than a 10,000 sq ft project because setup time is amortized over more area.
TI pricing often runs higher per-square-foot for the same total size, because:
- Setup time is similar but area is smaller
- Off-hours labor rates add 10–30%
- Dust control protocols add time
- Scope coordination with building management adds overhead
A 15,000 sq ft TI might quote at 1.5–2× the per-sf rate of a 100,000 sq ft new build final clean. That's not padding — it reflects real operational differences.
Key Takeaways
- New build = larger scope, predictable phasing, unconstrained access.
- TI = smaller scope but higher coordination complexity and strict dust control.
- Dust control requirements are the defining operational difference.
- TI scheduling often compresses phases and runs in off-hours.
- Per-sf pricing is naturally higher for TI — scale matters for unit economics.
