How Permitting and Inspections Work in Each State
While states establish minimum building codes (like the International Residential Code - IRC), the actual issuance of permits and the deployment of inspectors for GC structural work, Electrical rough-ins, Plumbing trenches, and HVAC ductwork is almost always managed by the local city or county building department.
Alabama
Local municipal inspectors verify GC framing, electrical panels, plumbing pressure tests, and HVAC ducting against state-adopted codes.
Alaska
Local jurisdictions inspect structural/electrical. State inspectors handle commercial life-safety. Deep frost-line plumbing inspections are heavily enforced.
Arizona
Local city/county departments inspect all GC framing, electrical service connections, plumbing trenches, and HVAC mechanical clearances.
Arkansas
Local building officials conduct all GC, electrical, plumbing, and HVAC phase inspections.
California
Local municipalities enforce rigorous state mandates, including strict seismic GC framing and Title 24 energy tests for HVAC duct leakage and lighting.
Colorado
Local building departments handle all phase inspections. GC framing heavily scrutinizes roof snow-load capacities.
Connecticut
State building code enforced locally across all trades (framing, electrical, plumbing, HVAC).
Delaware
Managed at the county level. Inspectors review structural framing, electrical grounding, plumbing venting, and mechanical rough-ins.
Florida
Highly rigorous local inspections. GC framing requires strict hurricane wind-load tie-downs. Electrical, plumbing, and HVAC must meet strict state wind and flood resistance codes.
Georgia
Local municipal enforcement for all structural, electrical, plumbing, and HVAC phases.
Hawaii
County-level departments conduct separate rough-in inspections for structural, electrical, plumbing, and mechanical.
Idaho
Centralized state permitting for rural areas (State plumbing/electrical inspectors); major cities run their own local inspections.
Illinois
Local cities and villages handle all framing, electrical, plumbing, and HVAC inspections.
Indiana
Local municipal inspectors check all trade rough-ins and finals.
Iowa
Local municipal enforcement across all structural and MEP codes.
Kansas
All GC structural, electrical, plumbing, and HVAC inspections are strictly locally run.
Kentucky
Centralized state framework, but physical phase inspections (framing, MEP) are enforced locally.
Louisiana
Uniform Construction Code enforced by local parishes, checking structural wind resistance, electrical, plumbing, and HVAC.
Maine
Local enforcement. Strict insulation inspections for GCs and deep-freeze protection codes for plumbing.
Maryland
County-level departments issue permits and run dedicated inspectors for building (GC), electrical, plumbing, and HVAC.
Massachusetts
Local inspectors enforce state codes, including very strict "stretch" energy codes for GC insulation and HVAC efficiency.
Michigan
Local townships issue permits and inspect GC framing, electrical panels, plumbing DWV, and mechanical systems.
Minnesota
State building code enforced via local municipal inspectors across all MEP trades.
Mississippi
Local municipal enforcement for all construction phases.
Missouri
No statewide code; local jurisdictions dictate and inspect all GC framing, electrical, plumbing, and HVAC.
Montana
State inspectors handle electrical/plumbing in rural areas; cities manage their own comprehensive GC/MEP inspections.
Nebraska
Local city enforcement for all structural and trade inspections.
Nevada
Strict local oversight. Clark County inspectors heavily scrutinize GC framing, electrical load calcs, plumbing, and HVAC mechanicals.
New Hampshire
Local municipal enforcement for all trades.
New Jersey
Uniform Construction Code (UCC) enforced locally. Requires highly sequenced, separate sign-offs for Building, Electrical, Plumbing, and Fire (HVAC).
New Mexico
Split jurisdiction. The state CID inspects rural areas (framing, electrical, plumbing, mechanical), while larger cities handle their own.
New York
Local jurisdiction (e.g., NYC Dept. of Buildings) issues separate permits and sends specialized inspectors for GC, electrical, plumbing, and HVAC.
North Carolina
State codes enforced by local county inspectors checking structural framing, electrical roughs, plumbing, and mechanical.
North Dakota
Local jurisdiction for all trade inspections.
Ohio
Residential structural, electrical, plumbing, and HVAC are primarily inspected at the local city/county level.
Oklahoma
Local municipal enforcement for all construction phases.
Oregon
State codes; local municipalities deploy inspectors for GC framing, electrical, plumbing, and mechanical (HVAC).
Pennsylvania
Uniform Construction Code (UCC) enforced locally, checking structural, electrical, plumbing, and HVAC.
Rhode Island
State building code enforced locally by municipal inspectors.
South Carolina
Local municipal enforcement for all trades.
South Dakota
Local city inspectors check framing, electrical, plumbing, and HVAC.
Tennessee
Local municipalities inspect all residential work; state fire marshal oversees some commercial HVAC/electrical.
Texas
Strictly local enforcement. Cities mandate specialized permits and phase inspections for framing, electrical, plumbing, and HVAC.
Utah
Local municipal inspections across all building phases and MEP trades.
Vermont
Local building permits; state inspectors often review specialized electrical and plumbing if municipalities lack inspectors.
Virginia
Local county/city inspectors check structural framing, electrical roughs, plumbing pressure, and mechanical HVAC.
Washington
Local city/county enforcement of state codes for framing, electrical, plumbing, and HVAC.
West Virginia
Local enforcement of state fire and building codes across all trades.
Wisconsin
Uniform Dwelling Code enforced locally; municipal inspectors check framing, electrical, plumbing, and HVAC.
Wyoming
Local jurisdiction for all permitting and GC/MEP phase inspections.
