What an allowance actually is
An allowance is a budget line the contractor inserted because you have not chosen the thing yet. "Tile allowance: $4/sq ft supplied." It covers labour at a real price and material at a guess.
That is a legitimate way to write a bid before selections are made. It becomes a problem when it is not labelled, not sized against anything real, and not accompanied by a process for what happens when you exceed it.
How to spot them
Sometimes the bid says "allowance". Often it does not. The tells are a suspiciously round number on a material-heavy line, a line with no product named, or a price well below what the same line costs in the other bids.
- Tile, at a per-square-foot supply price
- Plumbing and lighting fixtures
- Countertops, priced by stone group rather than by slab
- Appliances
- Cabinet hardware
- Flooring, where no product is named
Size them against what you will actually buy
Go and look at the tile you want before you sign. If the allowance is $4 per square foot supplied and the tile you have already pinned is $11, that is not a small overage — on 400 square feet it is $2,800, and it is entirely predictable today.
Do this for every allowance line. It takes an afternoon and it is the single highest-return hour in the whole process.
Ask what happens on the overage
The number matters less than the mechanism. Ask three things and get the answers in writing.
- If I exceed the allowance, do I pay the difference at cost, or at cost plus your markup?
- If I come in under, do I get the difference back?
- Who selects if I do not select in time, and by what date?
Fixed price is not automatically better
A fixed price on a line where you have not chosen anything is a contractor guessing and padding, and you pay for the padding whether or not you use it.
Allowances are honest when they are labelled, sized against something real, and paired with a clear rule for the difference. Unlabelled allowances presented as a price are what break budgets.
