For roofing contractors

Jurisdiction is the key to accurate estimates.

Guessing or miscalculating jurisdiction-specific costs destroys margins, delays approvals, and creates friction with carriers.

All of OneClick Code’s data is governed by the Authority Having Jurisdiction (AHJ) — calculated instantly and property-specific.

The Problem

The Costly Guessing Game of Estimating

Varying Costs

Permit fees and sales taxes aren’t standardized — they shift city to city, county to county, sometimes street to street. Two homes in the same ZIP can fall under different jurisdictions, each with their own:

  • Permit fee structures
  • Tax rates
  • Code enforcement policies

Time Wasted

To get the right numbers, contractors often call building departments (no answer), search outdated municipal sites, and get lost in documentation.

30–60 min per estimate — that should be spent closing jobs.

Financial Risk

Getting the jurisdiction wrong creates real problems:

  • OverestimateLose the bid to a competitor
  • UnderestimateAbsorb the difference, cut profit
  • Miss permitsFail inspections, delay approvals

Roofing is competitive. Every margin point counts.

Frequently asked questions

How does the permit fee calculator get its data?

OneClick Code aggregates permit fee structures directly from local municipalities, building departments, and verified jurisdiction sources. This data is continuously updated and validated to ensure accuracy for every property.

How do I know if the fee is lump-sum or percentage-based?

The report identifies how the jurisdiction calculates permit fees — flat rate, tiered system, or percentage of project value — so you understand exactly how the number was derived.

Does the sales tax feature cover all states and jurisdictions?

Yes. OneClick Code provides nationwide coverage, including state, county, and city-level tax data. Each calculation is tailored to the specific property location and applicable tax rules.

What is an “Authority Having Jurisdiction” (AHJ)?

The AHJ is the governing body responsible for enforcing building codes and issuing permits for a specific property — a city building department, a county agency, or a municipal authority. It determines which codes apply, what permits are required, and how inspections are conducted. OneClick Code identifies it automatically.

Every roofing project starts with one question: who governs this job?

The answer drives every code-enforceable data point in your estimate:

  • Drip Edge
  • Valley Liner
  • Sales Tax
  • Permit Fees
  • and more

OneClick is the answer you need.
