Idaho Masonry Contractor Registration Requirements (2026)

Idaho does not license masonry as a trade. Anyone engaged in construction in Idaho — including masonry contractors — must register with the Idaho Division of Occupational and Professional Licenses (DOPL) Public Works Contractors Section under Idaho Code Title 54 Chapter 52. Registration is by entity, not trade exam — there is no Idaho masonry exam. Public works projects above $50,000 additionally require a Public Works Contractor License (PWCL). This page documents the verified path including PWCL examination thresholds, OSHA silica enforcement, and TMS 402 / IBC Chapter 21 compliance.

Regulatory Oversight

Under Idaho Code Title 54 (Chapters 10 Electrical, 26 Plumbing, 45 Public Works Contractors, 50 HVAC, 52 Idaho Contractor Registration), Idaho Division of Occupational and Professional Licenses (DOPL) is the body that issues this license and enforces compliance with it. DOPL houses the Idaho Contractors Board, Electrical Board, Plumbing Board, and HVAC Board. It issues public works contractor licenses, contractor registrations, and individual trade licenses statewide, administers examinations, and handles discipline.

Application Process, Step by Step

Form an Idaho or foreign entity. Register your LLC or corporation with the Idaho Secretary of State and obtain an EIN.
Bind GL and workers compensation. Bind GL with minimum $300,000 per occurrence (most policies are $1M+) and workers comp for any employees.
Submit DOPL Contractor Registration. File the Idaho Contractor Registration with $150 fee, GL certificate, and workers comp certificate.
Receive registration number. DOPL issues the registration number; it must appear on every contract and ad per Idaho Code §54-5204.
Pull PWCL (public works only). For public projects above $50,000, additionally apply for the Public Works Contractor License with PSI exam, financial statement, and project class.
Pull project permits at the AHJ. Local building departments require permits for masonry on permitted projects; coordinate with the GC of record.
Implement OSHA silica program. Federal OSHA enforces 29 CFR 1926.1153 in Idaho; written exposure control plan and Table 1 controls are mandatory on every masonry job.

Frequent Application Errors

Drawn from the board instructions and sources cited on this page, the pitfalls below are the ones most likely to slow down or sink a Idaho Masonry application.

Operating without registration

Performing any construction work in Idaho without active DOPL Contractor Registration is unlicensed contracting under §54-5217 — first offense $1,000 fine, second is misdemeanor.

PWCL skipped on public projects

Public works above $50,000 require the PWCL in addition to basic registration. Pulling a public project without PWCL voids the contract and forfeits payment rights.

GL below DOPL minimum

Idaho requires $300,000 GL minimum at registration; smaller policies are rejected and the registration application is denied.

Anchored veneer ties undersized

Idaho seismic and high-wind exposure requires corrosion-resistant ties at TMS 402 spacing; Boise and Coeur d'Alene inspectors fail jobs with non-compliant ties.

Silica plan absent

OSHA targets Treasure Valley and Northern Idaho masonry sites; missing 29 CFR 1926.1153(g) plans draw immediate citations.
