How to Use This Construction Resource
Facility Authority is a national reference directory for the commercial and institutional construction sector. This page describes the structure of the directory, the professional categories it covers, the regulatory and licensing frameworks that define those categories, and how to locate relevant listings or reference material efficiently. The construction sector spans licensed contractors, specialty trades, engineering disciplines, and regulatory bodies — each with distinct qualification thresholds, permitting obligations, and inspection requirements.
Purpose of this resource
Facility Authority functions as a structured reference point for the US commercial construction sector — not as a licensing body, regulatory agency, or advisory service. The directory maps the landscape of facility construction services, from general contracting and civil work to specialty trades governed by state licensing boards and federal safety standards.
The construction sector in the United States operates under overlapping jurisdictional frameworks. At the federal level, OSHA 29 CFR 1926 governs construction safety, covering fall protection, scaffolding, excavation, and electrical hazards. The International Building Code (IBC), published by the International Code Council, provides the model building code adopted — with state and municipal amendments — across 49 states. The National Fire Protection Association's NFPA 101 Life Safety Code governs egress, occupancy classification, and fire protection systems in occupied structures. These frameworks shape which licensed professionals must be engaged on any given project, what permits are required before work begins, and what inspections must be passed before occupancy.
The directory reflects that regulatory structure. Listings are organized by trade category, service type, and geographic market so that project owners, procurement officers, facilities managers, and subcontractors can identify qualified providers operating within the correct licensing jurisdiction.
Intended users
Facility Authority serves four primary professional categories:
- Project owners and facilities managers — public agencies, private developers, healthcare systems, educational institutions, and industrial operators who procure construction and maintenance services and need to identify licensed, insured contractors operating in specific trades and jurisdictions.
- General contractors and construction managers — firms assembling subcontractor teams for commercial, institutional, or industrial projects who require trade-specific providers with verified license classifications.
- Specialty trade contractors — electrical, mechanical, plumbing, fire suppression, structural steel, concrete, and envelope contractors who operate under state-issued contractor licenses and bid on subcontracted scopes.
- Researchers and procurement analysts — individuals mapping the commercial construction supply chain for sourcing, due diligence, or market analysis purposes.
The directory is not structured for residential construction consumers. Commercial construction involves procurement thresholds, bonding requirements, and code classifications — such as the IBC's occupancy groups (A, B, E, F, H, I, M, R, S, U) — that differ substantially from residential building practice. An IBC Group I-2 occupancy (hospitals, nursing facilities) carries fire-resistance and egress requirements that have no equivalent in single-family residential code.

How to navigate
The directory is organized around three primary axes: trade category, project type, and geographic market.
Trade category follows the CSI MasterFormat division structure, the industry standard taxonomy published by the Construction Specifications Institute. Division 03 covers concrete; Division 26 covers electrical; Division 23 covers HVAC; Division 21 covers fire suppression. Locating a provider by division narrows results to contractors whose license classification aligns with the relevant scope of work.
Project type distinguishes between:
- New construction — ground-up projects requiring full permitting sequences, including site, foundation, structural, mechanical, electrical, plumbing (MEP), and certificate of occupancy inspections.
- Renovation and tenant improvement — work within an existing permitted structure, subject to existing conditions assessments and, in facilities built before 1980, asbestos and lead-based paint survey requirements under EPA NESHAP 40 CFR Part 61 Subpart M.
- Specialty facility construction — healthcare, laboratory, food processing, and industrial projects that trigger agency-specific overlays beyond local building department jurisdiction.
Geographic market matters because contractor licensing in the US is state-administered with no federal reciprocity standard. A general contractor licensed in Texas holds no automatic standing in California, where the Contractors State License Board (CSLB) issues separate classifications. Filtering by state ensures listed contractors hold the appropriate jurisdictional license.

What to look for first
Before engaging any contractor listed in the directory, three verification categories carry the most structural importance:
License classification and standing — State contractor license boards maintain public lookup tools. License class determines which scopes of work a contractor may legally perform. A C-10 electrical license in California, for example, does not authorize plumbing work. Misclassified scopes create permit rejection risk and potential stop-work liability.
Bonding and insurance thresholds — Commercial projects above certain contract values — thresholds vary by state and agency — require performance bonds and payment bonds under the Miller Act (40 U.S.C. §§ 3131–3134) for federally funded work. Private projects typically require bonding by contract rather than statute, but the threshold structures are comparable.
Safety program documentation — OSHA 29 CFR 1926 Subpart C requires written safety programs on commercial job sites. Contractors with documented Experience Modification Rates (EMR) below 1.0 — the industry baseline published by the National Council on Compensation Insurance (NCCI) — demonstrate statistically lower injury frequency than the sector average.
A contractor's permitting history, inspection pass rates, and any documented OSHA citations are public record in most jurisdictions and represent the clearest objective indicators of operational compliance. For project-specific questions not covered by directory listings, the contact page connects to directory administrators who can assist with categorization or listing inquiries.
