What are the prompt payment rules for construction in Pennsylvania?
Last reviewed July 5, 2026
In Pennsylvania, contractors must receive payment within 30 days of submitting a proper invoice. If the owner or GC disputes the invoice, they must notify the contractor within 14 days. Failure to do so can mean the invoice is deemed accepted. Retainage is capped at 10%.
Key points
- Payment due within 30 days after invoice submission.
- Disputes must be notified within 14 days.
- Retainage limited to 10%.
- Mechanics lien claims must be filed within six months.
Make sure you keep track of invoice submissions and any communications about disputes. If there's a delay in payment, it can affect cash flow and scheduling. Understanding these timelines can help avoid issues down the line, especially with lien rights if payments aren't made on time.
