License Requirements

Contractor licensing in the US and Canada is a patchwork. Some jurisdictions have strict boards. Others leave it to cities. Some require nothing at all.

Regulatory Models Explained

Decentralized

Each city sets its own rules. You may need separate licenses per city.

Regulatory Model Definitions

Centralized

A single state/provincial board issues a competency-based license (Exams + Experience).

Decentralized

No state-level GC license exists; contractors must register with individual cities/counties.

Registration

Mandatory state list for tax/insurance tracking, often without a competency exam.

Revenue Only

The "license" is purely a tax receipt; no proof of construction skill is required.

Hybrid

One sector (e.g., Residential) is State regulated, while Commercial is Local (or vice versa).

Credential

Credential-based licensing required for specific permits.

Licensing

Revenue or class-based licensing structure.

Dual System

Two parallel licensing systems exist for different contractor types.

Important Note About Municipal States

In decentralized states like Texas, a contractor licensed in Houston may need separate registration in Austin, San Antonio, and Dallas. There is no reciprocity between cities. Always verify local requirements.

What Verified Node Checks

Regardless of regulatory model, we verify contractor credentials against authoritative sources.

State database validation

We query official boards (CSLB, TDLR, ROC, RBQ) to confirm license status.

Municipal registration tracking

For decentralized states, we track city-level registrations where available.

Monthly re-verification

Licenses expire and get revoked. We check monthly to keep data current.
