Construction: Topic Context

The construction sector in the United States encompasses a broad range of regulated activities — from ground preparation and structural framing to mechanical installation, finishing trades, and commissioning. This page describes how the construction industry is structured, what regulatory frameworks govern it, and how project types, licensing categories, and permitting obligations define the operational boundaries professionals and facility owners encounter. The Facility Listings index provides access to verified contractors and service providers organized within this sector.

Definition and scope

Construction, as defined within the US regulatory and commercial landscape, refers to the erection, alteration, repair, improvement, demolition, or removal of any structure or facility — including the preparation of land for such work. The sector is classified by the North American Industry Classification System (NAICS) under Sector 23, which subdivides activity into building construction (NAICS 236), heavy and civil engineering construction (NAICS 237), and specialty trade contractors (NAICS 238).

The distinctions among these three divisions carry practical weight. Building construction covers residential and nonresidential structures where a general contractor typically assumes overall project responsibility. Heavy and civil engineering construction covers infrastructure work — highways, bridges, utilities, and site development — where public agency procurement and federal oversight are common. Specialty trade contractors — comprising electricians, plumbers, HVAC installers, concrete finishers, and related trades — perform defined scopes of work under subcontract or direct contract, each governed by state-level occupational licensing boards.

The Facility Directory Purpose and Scope describes how facility-focused construction services are organized for professional reference within this domain.

Federal regulatory authority over construction worksite safety is held by the Occupational Safety and Health Administration (OSHA), whose 29 CFR Part 1926 establishes the Safety and Health Regulations for Construction. This standard defines hazard classifications across fall protection, excavation, scaffolding, electrical, and personal protective equipment categories. The construction industry accounted for 1 in 5 private-sector worker fatalities recorded by OSHA in its most recent published annual data.

How it works

Construction projects advance through a series of defined phases, each with regulatory touchpoints and handoff requirements:

1. Pre-design and feasibility — Site assessment, environmental review, zoning verification, and utility coordination establish whether a proposed scope is permissible under applicable land-use regulations.
2. Design and permitting — Licensed architects or engineers prepare drawings and specifications; the authority having jurisdiction (AHJ) — typically a municipal or county building department — reviews and issues permits under the adopted building code. Most US jurisdictions have adopted the International Building Code (IBC) published by the International Code Council (ICC).
3. Site preparation and foundation — Earthwork, grading, and foundation construction proceed under permit. Excavation deeper than 5 feet is subject to OSHA's 29 CFR 1926 Subpart P cave-in protection requirements.
4. Structural framing — Wood, steel, or concrete framing is inspected by the AHJ at defined stages before concealment. Structural inspections are mandatory under IBC Chapter 17 for specific occupancy types and structural systems.
5. Mechanical, electrical, and plumbing (MEP) rough-in — Licensed specialty contractors install systems prior to insulation and drywall. Each trade typically carries a separate permit and inspection sequence.
6. Inspections and close-out — Final inspections by the AHJ are required before a Certificate of Occupancy (CO) or Certificate of Completion is issued. Without a CO, occupancy of a new commercial building is generally prohibited under state and local statutes.

Permit fees are set by local jurisdictions and are commonly calculated as a percentage of construction valuation — a structure valued at $1,000,000 in construction cost might carry a permit fee between $5,000 and $20,000 depending on jurisdiction fee schedules.

Common scenarios

Construction activity reaches across project types with distinct regulatory profiles:

Commercial ground-up construction involves new nonresidential buildings — office, retail, industrial, hospitality — where IBC occupancy classifications (A, B, E, F, I, M, R, S, U) determine fire-resistance ratings, egress requirements, and occupant load calculations. A Group I occupancy (institutional) faces more stringent fire and accessibility standards than a Group S occupancy (storage).

Tenant improvement (TI) work involves alterations to the interior of an existing commercial space. Even modest TI scopes typically require permits when they affect plumbing, electrical systems, fire sprinklers, or structural elements. The ADA Standards for Accessible Design, enforced under the Americans with Disabilities Act, apply to alterations that affect a facility's path of travel.

Infrastructure and site work on public projects triggers prevailing wage requirements under the Davis-Bacon Act (40 U.S.C. § 3141–3148) for federally funded contracts exceeding $2,000, requiring contractors to pay locally determined wage rates.

Renovation and historic structures involve additional review through the State Historic Preservation Office (SHPO) when federal funds or tax credits are involved, and may require compliance with the Secretary of the Interior's Standards for Rehabilitation.

Decision boundaries

Determining which regulatory framework applies — and which licensed professionals must be engaged — depends on a structured set of classification criteria:

General contractor vs. specialty contractor: A general contractor (GC) holds a license authorizing overall project management and self-performance of certain trades. Specialty contractors are licensed by state boards for defined scopes — 46 states require electrical contractor licensing; plumbing licensing requirements exist in all 50 states and the District of Columbia, though the issuing authority varies between state agencies and local jurisdictions.

Residential vs. commercial construction: The IBC applies to commercial and multi-family buildings above 3 stories; the International Residential Code (IRC) governs 1- and 2-family dwellings and townhouses up to 3 stories. These two code paths differ significantly in fire-resistance, accessibility, and structural requirements.

New construction vs. alteration: Alterations are generally required to bring only the altered scope into compliance with the current code, not the entire facility — subject to change-of-occupancy rules and AHJ discretion. A full gut renovation that changes occupancy classification from Group S to Group A, for example, triggers the full IBC compliance path for the new occupancy.
