I watched a client lose eleven days on a luxury Upper East Side gut renovation last spring. The delay did not come from permits, weather, or labor shortages. It came from a $180,000 pay application that sat in an owner's approval queue for 41 days while the steel vendor wanted cash on delivery. In New York construction, cash flow breaks schedules faster than cost overruns do. A right-sized line of credit turns uneven pay cycles into working capital you can plan around.

Why it matters

Two recent shifts have changed the financing picture for Tri-State builders. New York amended its Prompt Payment Act, effective December 19, 2025, and voided private contract terms that require retainage above 5 percent of the total contract sum. The SBA also launched its 7(a) Working Capital Pilot, which highlights project-based lines up to $5 million and can finance up to 100 percent of direct project costs. General contractors, specialty subs, and construction CFOs in the $5 million to $100 million revenue range face the same problem - job costs land every day, but cash lands in bursts. The firms that manage that gap well protect schedule, margin, and reputation.

The details

A construction line of credit works best when it fills short, predictable gaps between job costs and collected pay applications. The key limit is the borrowing base, which is the formula a lender uses to decide how much you can draw. Retainage is the share of each bill the owner keeps back until the end of the job, and on large residential or hospitality jobs with slow approvals, it can drain cash for months. A well-run line of credit protects schedule, strengthens bids, and keeps payment delays from turning into margin loss. Lenders move faster and price better when your package explains construction risk in a clean, familiar format.

  • On December 19, 2025, New York amended its Prompt Payment Act and voided private contract terms that require retainage above 5 percent of the total contract sum.
  • In fiscal year 2025, the SBA's Surety Bond Guarantee Program guaranteed 11,727 bonds with contract value above $10.5 billion.

The judge in the case will decide on Tuesday whether or not to allow Walker Reed Quinn out on bail.

The takeaway

This case highlights growing concerns in the community about repeat offenders released on bail, raising questions about bail reform, public safety on SF streets, and if any special laws to govern autonomous vehicles in residential and commercial areas.
