What Belongs in a Commercial Cleaning Scope of Work

A practical checklist for facilities managers in Tempe who want to evaluate bids on equal terms and avoid the most common scope disputes.

Why the scope of work is the most important document in a cleaning contract

The service agreement specifies the price and the payment terms. The scope of work specifies what you are paying for. Of the two, the scope is the document that determines whether you and your cleaning contractor agree on what constitutes satisfactory performance. When there is a dispute about service quality, the scope is what both parties refer to. If the scope is vague, both parties can be right at the same time, and that is where disputes become expensive.

Most commercial cleaning disputes in the Tempe market are not about whether someone showed up. They are about whether the scope was clear enough to establish what "showing up and doing the job" actually means. A detailed scope prevents most of these disputes before they start.

What a scope of work must specify

Space inventory

The scope should list every space being cleaned: offices by name or designation, restrooms by location and fixture count, conference rooms by name, breakrooms, lobbies, storage rooms and any areas explicitly excluded from the scope. "The office" is not a space inventory. "Three executive offices, 12 open-plan workstations, two conference rooms (west and east), one breakroom, two multi-fixture restrooms (first floor and second floor)" is a space inventory.

Task list per space

For each space, the scope should specify what tasks are performed. Common tasks and where they belong:

Frequency per task

Not all tasks are performed every visit. The scope should specify frequency for each task category: nightly, weekly, monthly, quarterly. VCT floor refinishing is not a nightly task; it belongs on a separate maintenance schedule. Carpet extraction is not a weekly task for most facilities. Touchpoint disinfection may be nightly during periods of high occupancy and weekly during low-occupancy periods. The scope should make these distinctions explicit.

Supplies: included or excluded

Restroom supplies (paper towel, toilet tissue, hand soap, seat covers, trash liners) are either included in the program price or billed at cost separately. This must be specified. A scope that does not address supplies will produce an invoice dispute within 90 days.

Access requirements and security protocols

The scope should specify the access window (earliest entry time, latest departure time), the access method (key, fob, code, security escort), which spaces require special authorization, and the protocol for locked or restricted areas encountered during cleaning. A crew that finds a locked door and skips that space without documentation creates a service gap; the scope should specify what happens in that situation.

What is explicitly excluded

Scope exclusions are as important as inclusions. Common exclusions in Tempe commercial facilities: personal items on desks, food from refrigerators, locked storage areas, server rooms, specific equipment surfaces, hazardous materials. If it is not specified as excluded, a dispute about whether it was included is likely.

Accountability and documentation

The scope should specify how service is documented: a sign-in log, a digital check-in system, a visit report, or a combination. For multi-tenant buildings, per-floor documentation allows individual tenants to confirm their space was serviced. For medical and regulated facilities, documentation may need to meet specific retention requirements.

Using the scope to compare bids

If you are soliciting multiple bids, ask each contractor to respond to the same scope document rather than allowing them to propose their own. This puts every bid on the same basis: you are comparing what it costs to deliver the same work, not comparing what different contractors think the work should be.

A contractor who cannot price against a written scope—who insists on writing their own proposal instead—is a contractor who does not want you to have a reference point for disputes. That is a data point worth registering before you sign anything.
