ALGORITHMIC VALUATION ENGINE
How We Estimate Subcontract Scope & Pricing
Municipal building permits record declared whole-structure valuations, not trade subcontractor line items. Here is how PermitRadar calculates trade-level bidding scopes—and how licensed subcontractors help calibrate our engine.
🏛️ The Reality of Municipal Permits
When a building permit is filed, the declared valuation often confuses subcontractors:
| Permit Observation | The Underlying Reality |
|---|---|
| $18,500,000 Permit | Whole-building commercial shell or apartment complex. A roofing or plumbing sub won't bid $18M—they bid their trade portion. |
| $1 or $0 Valuation | Contractors declare minimum statutory fee placeholders to minimize municipal filing fees. Actual build cost is normal market rate. |
| Master vs Sub-Permit | Some jurisdictions issue separate MEP sub-permits, while others bundle all scopes into 1 master building permit. |
⚙️ The Subcontract Engine
We convert raw municipal declarations into actionable subcontractor bid estimates using a three-tier algorithmic model:
1. Construction Cost Allocation Matrix (RSMeans / AGC):
Each trade represents an established percentage of whole-building construction budget (e.g. Commercial HVAC: 11%, Master Plumbing: 8%, Commercial Roofing: 7.5%, Electrical: 8%).
2. Square Footage Fallback Synthesis:
When a filing has $0 declared, we multiply verified square footage by regional building cost indices ($215/sqft custom residential, $90/sqft commercial alteration, $165/sqft addition).
3. Ground-Truth Contractor Calibration:
Real trade contractors in Texas and beyond submit live market pricing feedback, allowing our models to adjust for local labor & material swings.

Frequently Asked Questions
Why does an HVAC or plumbing permit show an $8,000,000 valuation?
In many municipalities, the jurisdiction lists the entire building project's master declared valuation on every sub-permit pulled under that parcel. PermitRadar automatically applies trade allocation percentages so you can evaluate the realistic subcontract amount.
How does PermitRadar handle permits filed with $0 or $1 valuation?
Many builders and developers write $0 or $1 on municipal applications to keep initial permit fee assessments low. PermitRadar inspects square footage, building type, and applies regional cost indices to establish a realistic baseline valuation.
Can I get municipal permits filtered specifically for my trade scope?
Yes! Our Contractor Portal features instant filtering by trade (Roofing, Commercial HVAC, Master Plumbing, Electrical, Solar) and county, ensuring you only receive high-signal opportunities matching your crew's capabilities.
