How to Use This Facility Resource
Facility Authority is a structured reference directory covering the construction services sector across the United States. This page describes how the directory is organized, what categories and classifications it covers, and how to locate specific facility-related service topics efficiently. The information here serves industry professionals, facility managers, contractors, and researchers navigating a complex and regulation-dense sector — not a general audience seeking introductory education.
What to look for first
The most productive entry point for any user is facility type and project classification. The construction services sector in the United States is segmented by occupancy class under the International Building Code (IBC), which assigns buildings to one of ten occupancy groups — including Assembly (Group A), Business (Group B), Institutional (Group I), and Industrial (Group F). These classifications determine which codes apply, what structural and fire-protection standards govern the project, and which inspections are required before occupancy is permitted.
A second organizing axis is project phase. Facility construction work falls into five discrete phases:
- Pre-development and site assessment — environmental review, zoning verification, geotechnical study
- Design and permitting — architectural drawings, engineering submissions, building department review
- Construction — structural, MEP (mechanical, electrical, plumbing), and specialty trade work
- Inspections and commissioning — code compliance verification, third-party commissioning for complex systems
- Occupancy and post-construction — certificate of occupancy, warranty periods, ongoing regulatory compliance
Knowing where a project or inquiry sits within this sequence determines which service providers, licensing categories, and code requirements are relevant.
For an overview of what this directory covers at the broadest level, the Facility Directory Purpose and Scope page establishes the classification framework and geographic reach of the listings.
How information is organized
Listings and reference content within Facility Authority are organized by three primary dimensions: facility type, trade category, and regulatory jurisdiction.
Facility type follows IBC occupancy classifications as the baseline, with additional overlays for federally regulated facility categories. Healthcare facilities, for example, are subject to Centers for Medicare & Medicaid Services (CMS) Conditions of Participation, which impose construction and life-safety requirements independent of local building codes. Industrial facilities subject to OSHA's 29 CFR 1910.119 Process Safety Management standard create a dual-track compliance structure distinct from purely commercial projects.
Trade category distinguishes between general construction, specialty trades (fire suppression, electrical, HVAC), and professional services (structural engineering, commissioning agents, environmental consultants). Licensing standards for these categories vary by state. General contractors in 45 states hold state-issued licenses; the remaining 5 states defer licensing authority to individual municipalities. Specialty trade licenses — particularly electrical and plumbing — are governed by separate state boards and carry distinct continuing education requirements.
Regulatory jurisdiction identifies whether a facility falls under local, state, or federal oversight — or a combination. NFPA 13 (Standard for the Installation of Sprinkler Systems) and NFPA 70E (Standard for Electrical Safety in the Workplace) are nationally referenced standards but are adopted and enforced at the state or local level, creating variation in applicability across jurisdictions.
The Facility Listings section reflects these organizational dimensions, allowing filtered access by facility type, trade, and state.
Limitations and scope
This directory covers the United States national market. It does not include Canadian provincial licensing structures, international building codes outside the U.S. adoption framework, or facilities governed exclusively by tribal or federal enclave jurisdiction where state codes do not apply.
The directory does not function as a licensing verification tool. Contractor license status changes continuously; authoritative verification requires direct queries to the relevant state licensing board (for example, the California Contractors State License Board or the Texas Department of Licensing and Regulation). Bond and insurance status must be confirmed through the issuing insurer or surety, not through directory listings.
Content on Facility Authority distinguishes between two broad types of reference material: structural reference (code frameworks, occupancy classifications, permit processes, agency jurisdiction) and service-provider listings (firms and professionals operating in specific categories and geographies). The structural reference content is stable across update cycles; listing data reflects the state of the directory at the time of last index and should be cross-checked against primary sources for active project use.
Permitting and inspection information describes general frameworks drawn from the IBC, NFPA codes, and named federal agency standards. It does not represent jurisdiction-specific code adoptions, which differ across the 50 states and the approximately 19,000 local building departments recognized by the International Code Council (ICC).
How to find specific topics
The directory supports three navigation approaches:
By facility category — Users with a known facility type (hospital, warehouse, educational building, food processing plant) should begin with the occupancy classification index. Each category page identifies the governing code framework, typical permit pathway, and relevant trade categories.
By regulatory subject — Users researching a specific compliance area (fire suppression, ADA accessibility under 28 CFR Part 36, hazardous materials handling under EPA 40 CFR Part 68) can locate reference content through the regulatory index, which maps named standards to facility types and trade categories.
By service type — Users seeking a specific professional category (commissioning agent, structural engineer, fire protection contractor) should use the trade category filter within Facility Listings, narrowed by state or metropolitan area.
