Pennsylvania splits the difference between licensing-heavy and licensing-light states: no statewide trade licenses, but a statewide consumer-protection registration with teeth, plus serious city-level licensing in Philadelphia and Pittsburgh. Here is the 2026 picture.
HICPA registration and local trade licenses
Any contractor performing more than $5,000 of home improvement work per year in Pennsylvania must register with the Attorney General under the Home Improvement Consumer Protection Act (HICPA), display the PA number on ads and contracts, and use written contracts with mandated terms for jobs over $500. It is registration rather than a competency exam, but the contract rules are enforced and unregistered contracting is a criminal offence. Electricians and plumbers are licensed locally: Philadelphia and Pittsburgh both run their own trade licensing, and many townships require registration tied to the state Uniform Construction Code permit process.
Mechanics liens and the Notices Directory
Pennsylvania liens must generally be filed within six months of completing your work, with formal notice to the owner required from subcontractors at least 30 days before filing. On larger projects (about $1.5 million and up) registered in the State Construction Notices Directory, subs and suppliers must file a Notice of Furnishing within 45 days of starting work or lose lien rights, a trap that catches out-of-state subs regularly. Suit follows within two years of filing.
Workers comp and tax
Workers compensation is mandatory from the first employee, no construction exception, with the State Workers Insurance Fund as the insurer of last resort. Contractors generally pay sales tax on materials as the consumer; certain repair and maintenance services carry tax, while construction contracts for real property improvements generally do not charge the customer sales tax directly.
OSHA and quick facts
Pennsylvania is a federal OSHA state. Keep HICPA contract terms in your quote template once and every job inherits compliance, which is exactly the kind of thing worth systemising rather than remembering.

Pennsylvania FAQs for trade businesses
Who has to register under HICPA?
Anyone performing more than $5,000 of home improvement work per year in Pennsylvania. Registration is simple, but the law also mandates written contract terms for jobs over $500, and violations are enforced by the Attorney General.
Do I need a trade license to wire or plumb in Pennsylvania?
Not from the state, but Philadelphia and Pittsburgh license trades directly and many townships require registration through their permit process, so the answer is city by city.
What is the Construction Notices Directory trap?
On registered projects of roughly $1.5 million and up, subs and suppliers must file a Notice of Furnishing within 45 days of starting work or lose lien rights entirely, and out-of-state subs miss it constantly.
