How We Calculate Baseline Index Prices

We index regional cost-of-living adjustments and local prevailing trade wage baselines to calculate exact labor adjustment factors per metro.
Municipal Permit Surcharges
Every calculation incorporates actual building department permit structures and inspection fees recorded across Travis, Harris, Miami-Dade, and 50+ counties.
Wholesale Freight & Material Baselines
Raw material commodity rates (steel coil, lumber, copper, asphalt) are adjusted for regional freight surcharges and distributor margins.
