Private Projects Private projects in Connecticut are governed by <https://www.cga.ct.gov/current/pub/chap_742b.htm> Conn. Gen. Stat. §§42-158i &#8211; 42-158j . These statutes regulate payment on all private construction projects in Connecticut, except: Projects funded by US Department of Housing and Urban Development Prime contracts of $25,000 or less Any residential projects containing 4 or less units Payment Deadlines for Private Projects On qualifying private projects in Connecticut, the property owner must pay the prime contractor within 30 days of invoice receipt.

Penalties for Late Payment on Private Projects Under Connecticut&#8217;s prompt pay laws for private projects, the interest rate on late payments is 1% per month until the balance is paid.
