10%
62 Pa.C.S. § 3921(a): a government agency may withhold no more than 10% of the amount due the contractor until the contract is 50% complete; at 50% completion half of the amount retained is returned to the contractor (with architect or engineer approval, satisfactory progress and no specific cause for greater withholding), and afterwards no more than 5% of the value of completed work may be withheld. Where the Department of General Services is the agency, the limits are 6% until 50% satisfactory completion and 3% of the original contract amount after that (§ 3921(b)). Where a prime contractor's claim against the agency rests on increased costs caused by delays or other actions of another prime contractor, additional retainage of one and one-half times the possible liability may be withheld unless the contractor causing the claim furnishes a satisfactory bond. The chapter applies to a contract exceeding $50,000 for construction and excludes Department of Transportation contracts under § 301(c)(1) (§ 3902).
Deadline
45 days
Substantial completion: after final inspection and the architect's or engineer's certificate, the agency pays in full within 45 days, less one and one-half times the cost of any remaining minor items.
What the statute says
A contract may include a provision for the retainage of a portion of the amount due the contractor to insure the proper performance of the contract except that the sum withheld by the government agency from the contractor shall not exceed 10% of the amount due the contractor until 50% of the contract is completed. When the contract is 50% completed, one-half of the amount retained by the government agency shall be returned to the contractor.

Who this applies to

These rules sit in Title 62 of the Pennsylvania Consolidated Statutes, the procurement title [1]. They govern what a government agency withholds from its contractor on a construction contract exceeding $50,000 [1], and the Department of General Services has a scale of its own [1]. Department of Transportation contracts under 62 Pa.C.S. § 301(c)(1) are outside the chapter's definition of a contract [1]. A related section, § 3922, carries payment down the chain: absent sufficient reason, the contractor pays subcontractors their earned share within 20 days [1] of receiving it.

The statute speaks to public contracts. Private work is not addressed by it, and this page does not cover private jobs; their retainage terms are a matter for the contract and a lawyer.

What the rule says

A contract may provide for retainage to ensure proper performance, within these limits [1]:

  1. Before the halfway point. The agency may withhold no more than 10% [1] of the amount due the contractor until 50% [1] of the contract is completed.
  2. At the halfway point. One-half of the amount retained is returned to the contractor. The return depends on the architect's or engineer's approval, satisfactory progress, and the absence of a specific cause for greater withholding [1].
  3. After the halfway point. The agency may withhold no more than 5% [1] of the value of completed work.

Where the Department of General Services is the agency, the figures are 6% [1] until 50% satisfactory completion and 3% [1] of the original contract amount after that.

A separate allowance covers multi-prime disputes. When a prime contractor's claim against the agency rests on increased costs caused by delays or other actions of another prime contractor, additional retainage of one and one-half times the possible liability may be withheld until the dispute is resolved, unless the contractor causing the claim furnishes a bond satisfactory to the agency [1].
