The direct answer
A new-home construction estimate should identify the exact plans and specifications priced, site and utility assumptions, trade scopes, allowances, alternates, contractor fees, insurance, permits, owner responsibilities, payment milestones, schedule basis, exclusions, and change-order rules. Undefined selections should not be presented as fixed costs.
What to check in the documents
Pricing documents
Record drawing dates, specification versions, addenda, engineering, finish schedules, and written clarifications used to prepare the estimate.
Site development
Check clearing, access, earthwork, soil conditions, drainage, utilities, impact fees, temporary services, surveys, and testing.
Trade completeness
Review boundaries between structure, roofing, enclosure, mechanical, electrical, plumbing, insulation, drywall, finishes, equipment, and exterior work.
Selections and allowances
Confirm amounts and assumptions for cabinets, counters, tile, flooring, fixtures, appliances, lighting, hardware, landscaping, and other selections.
General conditions and fees
Understand supervision, temporary facilities, insurance, cleanup, contractor fee, contingency, escalation, and taxes.
Warning signs to clarify
- Estimate does not identify drawing or specification dates
- Large undefined allowances across multiple finish categories
- Site costs carried as a single placeholder
- Owner responsibilities scattered or unstated
- Payment requests are not connected to understandable milestones
Questions to ask the contractor
- Exactly which plans and specifications were priced?
- Which site-development and utility costs are excluded?
- Are contractor fees and markups applied to allowances and changes?
- What must the owner purchase or coordinate?
- How does the payment schedule relate to completed work and stored materials?
Practical context
Example: an estimate total can change before construction starts
If the estimate was prepared from schematic plans, later structural design, energy requirements, finish selections, or site information may legitimately change the price. A clear proposal distinguishes preliminary assumptions from completed design so the homeowner understands which numbers are firm and which remain subject to development.
