You are comparing how different states organize construction regulation — board structures, licensing models, reciprocity agreements, and enforcement patterns. Every jurisdiction page normalizes the same data points so you can compare apples to apples.
This site restructures source material for readability. It does not replace official statutes, regulatory handbooks, or inter-agency agreements. Verify all details with the relevant jurisdiction before citing them in policy analysis or official recommendations.

​
What you need to know first

When comparing regulatory models, four structural questions matter most:
  1. Single board or split? — Some states route everything through one agency. Others split regulation across 5–10 boards by trade, project type, or dollar tier. The split changes how reciprocity, enforcement, and fee structures work.
  2. What triggers licensure? — Thresholds range from zero (all work requires a license) to six figures. Some states exempt subcontractors or residential work below a threshold.
  3. How does reciprocity work? — Statewide reciprocity is rare. Most agreements are board-specific, and some states have no formal arrangements at all.
  4. Where do local carve-outs apply? — Several states delegate licensing to cities or counties, creating a patchwork where statewide rules do not tell the full story.
The Special considerations → Regulators tab on every jurisdiction page gives you a structural summary before the detail sections. Use it to classify the state quickly.

Quick-start checklist

Follow these steps when evaluating a jurisdiction for regulatory comparison.

Classify the regulatory model

Open the jurisdiction page and read the intro line and At a glance table. Determine: single board, split board, local-first, or hybrid?

Map the board structure

Review the regulator directory. Count the agencies, note which trades each board owns, and identify unusual splits (e.g., fire marshal handling blasting permits).

Compare threshold triggers

Check the Construction work regulated table. Note which work lanes are exempt, which have dollar triggers, and which require licensure at any value.

Analyze reciprocity patterns

Review the reciprocal agreements table. Note whether reciprocity is statewide or board-specific, how many states are recognized, and whether NASCLA accreditation plays a role.

Cross-reference with comparison pages

Use the licensing thresholds, reciprocity rankings, and license types pages to see where this jurisdiction sits relative to peers.
If you can classify the model, map the boards, compare thresholds, and analyze reciprocity, you have a defensible structural comparison for that jurisdiction.

Example jurisdictions

These states represent the major regulatory models. Use them as reference points when classifying a new jurisdiction.

Alabama

Split-board model with 8 agencies. Board-specific reciprocity. A clear example of fragmented regulation.

California

Single-board model under CSLB. Centralized licensing with extensive trade classifications.

Florida

Dual-track model. State certification and local licensing coexist, with different paths for different trades.

Illinois

Local-first model. State-level regulation is limited; most licensing decisions happen at the city or county level.

Alaska

Statewide-heavy model. Centralized regulation with a straightforward single-board structure.

District of Columbia

Territory model with trade-specific licensing. Compact jurisdiction useful as a comparison baseline.
