US local service / home-project cost
How HI estimates home-project and local service costs from materials + labor.
How it's calculated
- Decompose the project into materials + labor
- Price materials from public / manufacturer references
- Apply BLS OEWS regional labor rates
- Cross-check against uncleared industry references
- Publish ranges with confidence
Assumptions
- Excludes permits unless specified
Limitations
- Depends partly on uncleared industry references — the dataset is not yet sellable
Formulas
cost = (area_sqft / coverage_per_gallon × coats × paint_price) + (area_sqft × labor_rate_per_sqft)
