Construction cost database
National project models are localized with state installation factors, then adjusted for size, finish, condition, complexity and selected scope.
Explore calculators →U.S. CONSTRUCTION COST INTELLIGENCE
A total is useful. Knowing what built it is better.
HomeCostGrid separates material, labor, permit and regional signals so you can challenge a budget without pretending a model is a quote.
Four layers. One honest range.
Material price layer
Material share stays visible instead of disappearing inside one total. Grade, system completeness, waste, freight and warranty are treated as separate questions.
Compare materials →Labor rate layer
Labor is modeled with local installation pressure, trade type, access, project complexity and contractor overhead—not a single national hourly wage.
Check state factors →Permit and code layer
Permit allowances are planning inputs only. The final authority is the local building department and the adopted code for the exact scope and address.
Check permit paths →EXPLORE THE MODEL
See what sits inside the total.
This is a planning decomposition—not a contractor quote. Change the project and state to see how the model separates materials, labor and overhead, permits and uncertainty.

READ THE NUMBER CORRECTLY
What the model knows—and what it does not.
Useful cost intelligence makes uncertainty visible. It does not hide missing address, condition or design information behind false precision.

Why not publish one price per square foot?
A single unit price hides demolition, access, fixed mobilization, finish level, code work and system completeness. HomeCostGrid keeps those drivers visible.
Are the numbers contractor quotes?
No. They are research and planning ranges designed to help scope a project and compare like with like before collecting address-specific bids.
How are real reports used?
Anonymous submissions stay private and pending until reviewed. Quote-only and legacy records stay outside completed-cost distributions; P25, median and P75 require at least 12 eligible completed-final reports.
How often should a budget be refreshed?
Refresh it before procurement, after design changes and whenever labor, material, permit or financing assumptions change.
