What is retainage in construction?

Answered by Netanel Presman, General Contractor (CSLB #1105249) · Updated

Short answer

Retainage is a percentage of each payment (typically 5-10%) held back from the contractor until substantial completion or final inspection. It protects the homeowner against defects and incomplete work. Most states cap retainage by statute. California caps it at 5% for public works, but residential retainage is set by contract and typically runs 5-10% until punch-list clearance.

In detail

Retainage (sometimes called "retention") is one of the most powerful contract tools a homeowner has to ensure a contractor finishes well. It creates a financial reason for the contractor to complete punch-list items and maintain quality through the final phase.

How retainage works:

  1. Draw schedule — contract specifies payments tied to construction milestones (permit, framing, rough-in, drywall).
  2. Percentage held — for each draw, 5-10% is withheld.
  3. Accumulation — over a $100,000 project with 10% retainage, $10,000 accumulates until project end.
  4. Release triggers — typically "substantial completion plus punch-list clearance" or "final city inspection."
  5. Final payment — retainage released together with the last draw.

Typical residential retainage structure:

  • 10% retainage on each draw (most common for mid-size residential remodels).
  • Reduced to 5% after substantial completion for 30-45 day punch-list window.
  • Final release after punch-list items are verified and lien waivers collected.

Why contractors sometimes push back:

  • Their own retainage on sub payments compounds cash-flow pressure.
  • For small contractors, 10% retainage strains working capital.
  • Some contractors offer discounted contract pricing in exchange for lower or no retainage — evaluate carefully; price discount rarely outweighs the financial leverage retainage provides.

State variations:

  • California (public works) — CCP §7107 caps retainage at 5% on public projects.
  • Florida — §713.60 permits retainage with notice to owner.
  • Texas — residential retainage is contractual.
  • New York — Prompt Payment Act caps retainage at 5% on private projects over certain thresholds.

Common retainage pitfalls:

  • Contract doesn't specify what triggers retainage release.
  • Contract ties retainage release to city final inspection, but city takes 60+ days to inspect.
  • Homeowner withholds retainage unreasonably; contractor files lien.

Good-practice release language: "Retainage shall be released upon satisfaction of all of the following: (a) final building department inspection passed; (b) all punch-list items completed; (c) unconditional lien waivers received from all subcontractors and suppliers; (d) as-built drawings delivered if applicable."

AskBaily's contract template uses 10% retainage dropping to 5% at substantial completion, with clear release triggers.
