The direct answer
Common construction contract red flags include vague scope, missing documents, undefined allowances, one-sided change-order authority, front-loaded payments, broad owner responsibilities, incomplete schedule language, conflicting proposal terms, unclear completion requirements, and verbal promises that never enter the written agreement.
What to check in the documents
Contract documents
Identify every proposal, drawing, specification, addendum, selection, schedule, and clarification incorporated into the agreement and the order of precedence.
Scope and exclusions
Confirm the work, materials, responsibilities, quality assumptions, exclusions, and owner-supplied items are specific enough to administer.
Price and payment
Understand fixed amounts, allowances, unit prices, fees, deposits, progress billing, stored materials, final payment, and permitted adjustments.
Changes and delays
Check written approval, pricing, markup, schedule effects, concealed conditions, owner changes, and who may direct work.
Completion and closeout
Define substantial or final completion, punch-list handling, inspections, warranties, manuals, releases, cleanup, and document delivery.
Warning signs to clarify
- Blank exhibits or documents referenced but not attached
- Contractor may change price or scope without written owner approval
- Payment gets substantially ahead of progress
- Important proposal promises conflict with the contract
- Owner is asked to rely on verbal explanations instead of revisions
Questions to ask the contractor
- Which documents are part of the agreement, and which controls a conflict?
- Can added work proceed before written price and schedule approval?
- What exactly supports each payment?
- How are delays and concealed conditions handled?
- What must happen before final payment is due?
Practical context
Example: a proposal promise can disappear in the contract
A contractor's proposal may include a detailed scope, while the later contract contains a broad integration clause and does not attach that proposal. Unless the final agreement clearly incorporates the accepted proposal, the homeowner may have difficulty showing that its details were intended to control.
