Tennessee Plumbing Industry: Employment and Market Data

Tennessee's plumbing sector represents a significant segment of the state's construction and skilled trades economy, encompassing licensed contractors, journeymen, apprentices, and specialty trade workers across residential, commercial, and industrial segments. Employment figures, wage benchmarks, and market structure data inform workforce planning, licensing policy, and contractor pricing across the state. This page describes the industry's employment landscape, wage data, market composition, and the regulatory context that shapes labor demand in Tennessee's plumbing trades.

Definition and scope

The Tennessee plumbing industry, for purposes of employment and market analysis, includes all workers and businesses engaged in the installation, maintenance, repair, and inspection of potable water systems, drainage systems, gas piping, and related mechanical infrastructure. The Tennessee Department of Labor and Workforce Development tracks plumbing employment under Standard Occupational Classification (SOC) codes 47-2152 (Plumbers, Pipefitters, and Steamfitters) as defined by the U.S. Bureau of Labor Statistics.

The Tennessee State Plumbing Board, operating under the Tennessee Department of Commerce and Insurance (TDCI), licenses contractors and master plumbers and maintains the legal framework governing who may perform compensated plumbing work in the state. The market scope covered here is limited to Tennessee-licensed activity. Work performed under federal jurisdiction on federal facilities, or plumbing performed by unlicensed workers in jurisdictions that have not adopted state oversight, falls outside the primary regulatory scope described here.

The Tennessee plumbing industry statistics resource provides supplementary quantitative breakdowns by region and license category.

Scope limitations

This page covers Tennessee state-licensed plumbing employment and market data only. Federal employee classifications, multi-state contractor operations not domiciled in Tennessee, and purely mechanical or HVAC trades without plumbing licensure overlap are not covered. Septic system installation, while intersecting with plumbing work, falls under Tennessee Department of Environment and Conservation (TDEC) jurisdiction and is addressed separately at Tennessee Septic and Plumbing Intersection.

How it works

Tennessee's plumbing labor market functions through a tiered licensing structure administered by the Tennessee State Plumbing Board. The primary license tiers — apprentice, journeyman, master plumber, and contractor — each carry distinct qualification thresholds and scope-of-work permissions. Wage rates and employment demand track closely to license tier, project type (residential vs. commercial), and geographic region within the state.

Labor market data for the sector flows through three primary channels:

U.S. Bureau of Labor Statistics Occupational Employment and Wage Statistics (OEWS) — annual surveys covering statewide and metropolitan-area employment counts and wage percentiles for SOC 47-2152
Tennessee Department of Labor and Workforce Development — state-level unemployment insurance wage records and workforce projections
Tennessee State Plumbing Board license data — active license counts by category, renewal rates, and new license issuances per year

According to the U.S. Bureau of Labor Statistics OEWS program, Tennessee employed approximately 12,700 plumbers, pipefitters, and steamfitters as of the most recently published state-level estimates. The annual mean wage for this occupation in Tennessee was reported at approximately $58,000, with the 90th percentile exceeding $84,000 (BLS OEWS Tennessee).

The regulatory context for Tennessee plumbing page describes how licensing requirements directly influence workforce composition and which contractors may legally bid on permitted work.

Common scenarios

Market and employment data surfaces in several recurring operational contexts across the Tennessee plumbing sector:

Contractor workforce planning — Plumbing contractors in Tennessee use state and federal wage data to benchmark compensation for journeymen and master plumbers. The gap between Tennessee's mean plumber wage and the national mean (approximately $62,000 nationally per BLS OEWS national data) affects recruitment for firms operating in border markets such as the Memphis metropolitan area, which competes with Arkansas and Mississippi labor pools, and the Tri-Cities region, which borders Virginia.

Apprenticeship program sizing — Registered apprenticeship programs affiliated with the Tennessee Plumbing Apprenticeship Programs network use projected demand figures from the Tennessee Department of Labor's labor market information division to calibrate class sizes and training capacity. The state projects a 5% employment growth rate for plumbing occupations over a 10-year horizon, consistent with national projections published by the BLS Occupational Outlook Handbook.

Licensing policy analysis — The TDCI and the Tennessee State Plumbing Board reference active license counts and renewal data when assessing workforce sufficiency. A decline in active journeyman licenses relative to contractor licenses, for example, signals a compression in the qualified worker pool. Industry associations such as those listed in the Tennessee Plumbing Associations and Organizations directory submit workforce data to inform licensing fee structures and examination schedules.

Market entry for contractors — New entrants to the Tennessee plumbing market, including contractors relocating from other states, review employment density and wage data for target regions before establishing operations. Tennessee's reciprocity provisions for out-of-state license holders intersect with market entry decisions.

Decision boundaries

The employment and market data framework carries specific boundaries that shape how figures should be interpreted:

Residential vs. commercial segmentation: BLS SOC 47-2152 aggregates residential and commercial plumbers under a single classification. Tennessee's licensing framework distinguishes between these segments through separate contractor license categories. Wage and employment comparisons between segments require cross-referencing license type data from TDCI with BLS OEWS figures.
Metro vs. rural divergence: The Nashville-Davidson–Murfreesboro–Franklin metropolitan statistical area and the Memphis MSA carry wage and employment densities substantially above rural counties in West Tennessee and the Cumberland Plateau. Statewide averages do not reflect the conditions in individual regions. The Tennessee plumbing in local context resource documents regional variation.
Licensed vs. total workforce: BLS employment figures capture workers reported through employer payroll surveys and may not fully reflect sole-proprietor licensed master plumbers operating without employees. The TDCI license count provides a separate measure of the credentialed workforce.
Intersection with gas work: Plumbers licensed for gas piping in Tennessee operate under both plumbing board jurisdiction and, for certain appliance connections, under requirements administered by the Tennessee Department of Commerce and Insurance Fire Prevention Division. Employment figures for gas-related plumbing work appear within the broader SOC category and are not separately enumerated in standard BLS reporting.
