A service contract is a recurring agreement between a property owner or manager and an outside vendor to perform a defined building service, such as HVAC maintenance, janitorial work, landscaping, or elevator servicing. It sets the scope, schedule, price, and duration of the work. It is also called a vendor service agreement.
How Does a Service Contract Work?
A service contract works by binding a vendor to a defined scope of work at an agreed price over a set term, in exchange for the owner's commitment to pay. The contract specifies what tasks the vendor performs, how often, at what rate, and for how long, plus insurance, liability, and termination terms. It converts an ad hoc repair relationship into a predictable, scheduled service.
Per the National Property Services Authority, a property services contract is a binding instrument defining the scope, duration, compensation, and performance obligations of a service relationship on real property. The core clauses an operator confirms are scope of work, pricing structure, term and renewal, and a certificate of insurance naming the owner as additional insured.
Clause | What it defines |
Scope of work | The specific tasks and their frequency the vendor will perform |
Pricing | Flat fee, per visit, per square foot, or time and materials |
Term and renewal | Contract length and whether it auto-renews |
Insurance and liability | Required coverage and who bears risk for damage |
Termination | Notice period and conditions to exit the agreement |
Pricing structure is where cost risk sits. According to getJones's guidance, a certificate of insurance naming the owner as additional insured is standard, transferring liability for on-site injury or damage to the vendor. A contract without that certificate leaves the owner exposed.
Why a Service Contract Matters
A service contract matters because it fixes both the price and the accountability for recurring building work, turning a variable expense into a budgeted line and a scope a vendor is obligated to meet. Without it, an owner negotiates every repair from a weaker position and absorbs whatever emergency rate the market sets that day. The contract is leverage and predictability.
Contract pricing varies widely by scope. Per commercial HVAC maintenance guidance compiled by Oxmaint, per-square-foot HVAC maintenance plans commonly run in the range of $0.12 to $0.65 per square foot per year, with labor-only plans at the low end and full parts-and-labor coverage at the high end. A well-scoped contract also shifts emergency-repair risk to the vendor when it includes response-time commitments.
The quotable point for a property manager: a service contract is only as strong as its scope of work. A vague scope invites change orders and disputes; a tight scope makes the vendor accountable for a defined result at a fixed price.
Example
An owner puts a 60,000 square foot office building under an HVAC service contract at $0.30 per square foot per year, full parts-and-labor coverage, billed monthly. The annual price is fixed, and emergency repairs within scope are included rather than billed separately.
Line | Calculation | Result |
Rate | Given | $0.30 / sq ft / yr |
Building area | Given | 60,000 sq ft |
Annual contract cost | $0.30 x 60,000 | $18,000 |
Monthly billing | $18,000 / 12 | $1,500 |
The contract costs $18,000 per year, or $1,500 per month. If a compressor fails and the same repair would have cost $9,000 out of contract, the full-coverage scope absorbs it, so the owner's cost stays $18,000 rather than $27,000. The trade is a known annual fee against an unknown repair exposure, and the numbers above are illustrative of a mid-tier scope, not a quoted price.
Variations and Edge Cases
A service contract is not a single template: pricing model and coverage depth vary by trade and negotiation. The same building system can be contracted labor-only or full coverage, at very different prices and risk splits. The table below separates the structures an operator should distinguish before signing.
Structure | Trade-off |
Labor-only | Lower fee, but the owner pays for all parts separately |
Full coverage (parts and labor) | Higher fee, but repairs within scope are included |
Time and materials | No fixed fee; billed per visit, exposing the owner to variable cost |
Per square foot | Priced on building area, common for HVAC and janitorial |
Auto-renewal | Rolls over unless canceled by a notice deadline, easy to miss |
The common mistake is missing the auto-renewal notice window. Many service contracts renew automatically and require written notice 30 to 90 days before term end to exit, so an owner who wants to rebid the work can be locked into another term by inaction.
Service Contract vs Warranty
A service contract is often confused with a warranty, but they cover different things. A service contract is a paid, recurring agreement to perform ongoing maintenance and service on a building system. A warranty is a manufacturer's or installer's guarantee to repair or replace a specific defect, usually free, for a fixed period after purchase.
The warranty is defect coverage tied to the product; the service contract is scheduled upkeep the owner pays for regardless of defect. A new rooftop unit may carry a five-year parts warranty, but that warranty does not change filters, clean coils, or respond to a Sunday breakdown. Those are the service contract's job. The two coexist: warranty for defects, contract for maintenance.
