Worth knowing: UA Local 5 Baltimore is one of the larger UA Local plumbing + pipefitting unions in the Mid-Atlantic at ~3,000 active members. Maryland's non-right-to-work status (MD is NOT RTW; ~10.2% union density 2024) supports robust UA Local membership. The Whiting-Turner Contracting HQ Baltimore (~$13B annual revenue, one of the largest US construction firms) plus Clark Construction senior project portfolios drive substantial commercial + healthcare + hospitality plumbing demand. NIH Bethesda facility expansion + Walter Reed renovation + Aberdeen Proving Ground modernization + Fort Detrick infrastructure all require cleared journeyman work at . ASSE 6010 medical-gas certification (required for hospital plumbing including O2/N2/medical air installation at Hopkins + UMMS + MedStar facilities) drives the highest-comp journeyman specialty at $130-180K w/OT. The 2025 No Tax on Overtime federal deduction applies to non-exempt plumber OT premium pay for tax years 2025-2028 — cap $12,500 single / $25,000 above-the-line. For a UA Local 5 journeyman at $95K base plus $25K OT premium ($120K total), OBBBA produces ~$5,500 federal + potential ~$1,190 MD savings = ~$6,690 cumulative through 2028. The MD combined effective rate at journeyman comp ($120K, Montgomery County 3.20% piggyback) is ~7.95%; suburban Anne Arundel residency at 2.81% piggyback saves $470/year.
