Where the data comes from
Content is sourced from NASCLA (National Association of State Contractors Licensing Agencies) and supplemented with direct review of state regulator websites, statutes, and administrative codes.NASCLA data provides the structural backbone. The CSLID restructures, normalizes, and supplements that data — it does not independently audit or verify it.
How current is it?
Content reflects a point-in-time snapshot. Regulatory requirements change as legislatures amend statutes, boards update fees, and agencies revise application procedures.
Changes frequently:
- Fee schedules — boards adjust fees annually or with budget cycles.
- Reciprocity agreements — added, modified, or terminated by individual boards.
- Exam requirements — testing providers, pass rates, and content areas evolve.
- Contact information — phone numbers, addresses, and staff change regularly.
- Dollar thresholds — set by statute and require legislative action to change.
- Board structures — agency reorganizations are infrequent.
- Work-lane classifications — the categories of regulated work are relatively stable.
How we present the data
Source material is rewritten in plain English — you should not need to interpret statutory language to find what you need. Every state page follows the same 12-section layout so you can learn it once and apply it everywhere. Factual data — thresholds, fees, board names, reciprocity lists — is never altered. The presentation is restructured for clarity: tables replace paragraphs, accordions replace long lists, and role-specific tabs surface what matters to contractors and regulators before the detail sections.Limitations
Verification guidance
Before relying on any data point in the CSLID for a decision:Check the live regulator website
Every jurisdiction page includes regulator contact information in the Who regulates construction section. Visit the linked website to confirm current requirements.
Confirm fee schedules
Fees change frequently. Check the regulator’s current fee schedule, not the snapshot in the CSLID.
Verify reciprocity status
Contact the target board directly to confirm that a reciprocal agreement is still active and that your credential qualifies.
Check for recent legislative changes
Search for recent session laws or administrative rule changes that may have modified thresholds, exemptions, or licensing requirements since the content in the CSLID was last updated.
