Moving to New York as a master plumber: every state's rule
New York does not issue a statewide master plumber license, so there is no reciprocity to speak of. Here is what that means in practice.
New York master plumber · “Master Plumber (municipal)”
Licensed by cities and counties
Issued by New York cities and counties (no statewide plumber licence)
New York does not issue a statewide master plumber licence. The Department of State Division of Licensing Services' 35 occupations do not include plumber. The person-held contracting credential is municipal. Westchester County requires a Master Plumber trade licence to contract in the county (exam application $50, licence and renewal $600; Restricted Master renewal $50 per municipality up to $600); Yonkers sits inside that county. Rochester lists Plumbing Licensing on its Licensed Trades portal without publishing fees.
How local licensing works in New York
How local licensing works. Master plumber licensing is entirely local. A Master Plumber licence from one New York city or county does not authorise work in another, and New York State has no endorsement or reciprocity programme for plumbers. There is no defaultPath and no agreements array at this level.
New York City. 'Master Plumbers are licensed to perform plumbing work in New York City.' Fees on the DOB master-plumbers page: licence $200.00, renewal $150.00, late $50.00 (1–30 days) or $100.00 (31 days or more), seal $50.00 new / $75.00 renewal, term 3 years. Written exam application LIC41 $585; practical exam application LIC42 $530. A separate Master Fire Suppression Piping Contractor licence uses the same fee/term schedule but does not cover plumbing work as defined in NYC Admin. Code §28-401.3.
