Multi-Unit Painting: Build a Scope Matrix Before Comparing Bids
Use a unit-by-unit matrix to compare repaint scopes, repair allowances, occupied access, color schedules, changes, and closeout records across a building.
By NYC Painting Pros Team
Two buildings with the same number of apartments can produce very different painting proposals. Unit sizes, condition, occupancy, access, and included surfaces all matter. A scope matrix makes those differences visible before a single blended price hides them.
The matrix is a working procurement document, not a substitute for site assessment. Start with one row per unit or work zone and enough detail to let bidders identify the same base work, exceptions, and assumptions. Keep resident information limited to what the project actually needs.
Give each unit a comparable base scope
Identify walls, ceilings, doors, trim, and closets as separate inclusions. Record the approved product and color schedule. Define what routine preparation includes so one bidder does not assume minor patching while another assumes extensive wall repair.
If units fall into recurring types, use those types as a starting point but record exceptions after inspection. A matching floor plan does not prove matching condition. Photos should carry the unit or zone identifier and a clear location note.
| Matrix field | Example of useful detail |
|---|---|
| Unit or zone | Internal project identifier |
| Occupancy and access | Vacant; keys controlled by management |
| Included surfaces | Walls and ceilings; doors separately priced |
| Condition exceptions | Bedroom wall repair pending assessment |
| Finish schedule | Product, color, and sheen code |
| Readiness | Repairs complete; access confirmed |
Separate the base price from exceptions
Request a defined method for pricing additional repairs, extra colors, or surfaces outside the base scope. Decide who can authorize changes and what evidence is needed. Photographs and a written description should come before an expanded scope is treated as approved.
For example, a unit with wallpaper removal should not silently inherit the same preparation allowance as a sound painted unit. Keep it as an explicit exception or separately priced package. This makes both the estimate and the final invoice easier to reconcile.
Use readiness gates, not just calendar slots
A unit is ready when access, prerequisite repairs, materials, and required arrangements are confirmed. A date alone does not establish readiness. Track those items so a crew is not scheduled into a unit that cannot be worked on.
For covered work in older housing, review EPA's property-manager RRP guidance and confirm the required firm qualifications and practices before procurement is finalized. Keep applicable compliance arrangements distinct from a generic claim that a contractor is insured.
- Approved scope and color schedule
- Access and resident coordination confirmed
- Prerequisite repairs complete
- Applicable qualifications and requirements checked
- Change approver identified
Close out by unit and surface
Record completion, punch-list items, product details, and photographs for each unit or zone. Distinguish 'crew finished' from 'accepted' and identify the person responsible for resolving open items. A building-wide completion percentage is not enough to explain what remains.
Use the same matrix for maintenance afterward. A location-based finish record allows later touchups to begin with the right product information and avoids mixing leftover paints with similar names but different sheens or formulations.
