A fixed selection gives the contract a defined product, scope or price basis. An allowance reserves an amount for work or materials that are not fully selected or quantified when the contract is signed.
Allowances can keep a project moving when a decision is genuinely unresolved. They can also make a low initial contract price look more certain than it is.
The useful question is not, “Are allowances bad?” It is: What exactly does the allowance include, what happens when actual cost differs, and who must approve the change?
Terms vary—read the contract definition
Construction terms are not perfectly uniform across every contract or jurisdiction. The agreement should define its own use of material allowance, labor allowance, installation allowance, unit price, contingency, alternates, owner-provided item and change order.
An allowance is not necessarily the same as a contingency. AIA guidance describes contingency as a predetermined amount or percentage held for unpredictable project changes. An allowance more commonly addresses an item or scope that is expected but not fully selected or priced.
What a fixed selection provides
A fixed selection should identify enough detail for the parties to understand the price basis. Depending on the item, that may include manufacturer and model, size, finish, quantity, accessories, delivery, taxes, installation labor, rough-in requirements, disposal and warranty or commissioning. A product name without installation scope can still leave a budget gap.
What an allowance should say
- What item or scope does it cover?
- Is it materials only or installed cost?
- Are tax, delivery, handling and markup included?
- What quantity or unit is assumed?
- Who selects the item?
- When must the selection be made?
- What supports actual cost?
- How are overages and credits calculated?
- Does the selection affect schedule or other work?
- What written approval is required before purchase or installation?
Allowances and fixed selections compared
| Question | Fixed selection | Allowance |
|---|---|---|
| Product or scope known at signing? | Usually defined | Partly unresolved |
| Price certainty | Higher when scope is complete | Lower until reconciled |
| Owner flexibility | Lower after contract | Higher within schedule and budget limits |
| Change-order exposure | From scope or selection change | From cost, quantity, labor or timing differences |
| Key document | Specification or selection schedule | Allowance schedule and reconciliation method |
Neither column guarantees the final cost. Concealed conditions, design changes and incomplete scope can affect both.
Where budgets drift
Material-only allowance treated as installed cost
A fixture allowance may cover purchase price but exclude tax, delivery, rough-in changes, installation, accessories or disposal.
Quantity is not defined
A per-item amount does not establish the number of items. A lump-sum allowance without quantity can hide a scope disagreement.
The selection arrives late
A product may fit the dollar allowance and still delay the project because of lead time, approvals or rough-in changes.
Markup is unclear
The contract should say how overhead, profit or other markup applies to allowance differences.
Credits are handled differently from overages
The reconciliation method should explain both. A transparent allowance is not only a mechanism for charging more.
A selection changes adjacent work
A heavier, larger or differently powered item may affect framing, electrical, plumbing, ventilation, finishes or permits.
Work starts before written approval
AIA change-order guidance emphasizes documented changes and agreement by the parties responsible for the contract. Public-sector examples define a change order as a written instrument addressing changed work, contract sum and contract time.
The exact legal rule depends on the agreement and jurisdiction. As project control, written authorization before changed work is safer than reconstructing the decision later.
Build an allowance schedule
Track the item, amount and basis, included costs, selection deadline, approval parties, actual cost and resulting change or credit. The schedule should point back to the controlling contract language; it is not a replacement for the agreement.
Before signing
Ask for every allowance, quantity and quality assumptions, included and excluded costs, the reconciliation formula, markup treatment, selection deadlines, lead-time assumptions, approval authority and a sample change-order process.
If a major scope is represented by a placeholder, compare proposals on the same assumptions. A low allowance can make one bid appear cheaper even when the likely installed scope is similar.
During the project
- Make selections by the documented deadline.
- Obtain a written price impact before ordering.
- Record schedule and adjacent-trade effects.
- Keep product approvals and required support.
- Reconcile credits as well as overages.
- Update contract sum and time through the agreed written process.
- Keep the allowance schedule and change log current.
Red flags
- no written scope;
- “installed” is not defined;
- quantities are absent;
- the number appears far below the stated quality level;
- markup treatment is missing;
- the selection deadline follows the procurement deadline;
- verbal approval is treated as complete authorization; or
- credits are not addressed.
These are reasons to clarify the agreement, not proof of misconduct.
Frequently asked questions
Is an allowance part of the contract price?
Often yes, as a placeholder subject to the contract’s reconciliation terms. Read the agreement; treatment varies.
Is an allowance the same as a contingency?
Not necessarily. A contingency generally addresses uncertain project risk, while an allowance commonly addresses an expected but unresolved item or scope.
Does choosing an item within the allowance prevent a change order?
Not always. Installation, tax, delivery, quantity, markup, schedule or adjacent work may differ from the allowance basis.
Should changed work begin before the price is agreed?
Follow the contract and applicable law. As project control, document scope, price and schedule authorization before changed work whenever possible.
