Maryland retainage law: 5% bonded cap, 90- and 120-day release (2026)

Quick answer

Maryland caps retainage at 5% when the contractor has furnished 100% performance and 100% payment security. Private work (Real Property § 9-304, contracts of $100,000 or more): the owner pays undisputed retention within 90 days after substantial completion as the contract defines it. Public work (State Finance and Procurement § 17-110): the public body releases it within 120 days after satisfactory completion.

Retainage cap
5%
The 5% ceiling applies where the contractor has furnished 100% performance security and 100% payment security; it caps both the retention across the contract and the retention from any single payment. The section does not apply to a contract under $100,000 or to a project funded wholly or partly by or through the Department of Housing and Community Development. Amounts beyond retainage may still be withheld for reasonable grounds relating to performance.
Deadline
90 days
Undisputed retention proceeds retained by an owner must be paid within 90 days after the date of substantial completion, as substantial completion is defined by the applicable contract or subcontract.
What the statute says
If a contractor has furnished 100% security to guarantee the performance of a contract and 100% security to guarantee payment for labor and materials, including leased equipment: (i) The retention proceeds under the terms of a contract may not exceed 5% of the contract price; and (ii) The retention proceeds of any payment due under the terms of a contract from an owner to a contractor may not exceed 5% of the payment.

Retainage cap
5%
Where the contractor has furnished 100% payment security and 100% performance security, 'the percentage specified in the contract for retainage may not exceed 5% of the total amount of the contract'. Public bodies may still withhold additional amounts reasonably believed necessary to protect the public body's interest. State procurement units and the Maryland Transportation Authority are governed by the parallel § 13-225, which also permits retainage to be placed in an interest-bearing escrow under § 15-108 with interest paid pro rata.
Deadline
120 days
Within 120 days after satisfactory completion of a contract for construction the public body must release any retainage due; if there is a dispute or contract claim about satisfactory completion, within 120 days after the dispute or claim is resolved.
What the statute says
If a contractor has furnished 100% payment security and 100% performance security in accordance with this subtitle under a contract for construction awarded by a public body, the percentage specified in the contract for retainage may not exceed 5% of the total amount of the contract.

Who this applies to

Maryland ties its retainage ceiling to bonding, and it writes separate sections for private and public work.

Private construction

Real Property § 9-304 sets the private rule [1]. It does not apply to a contract under $100,000, or to a project funded wholly or partly by or through the Department of Housing and Community Development [1]. Its 5% limit applies where the contractor has furnished 100% performance security and 100% payment security [1].

Public construction

State Finance and Procurement § 17-110 covers construction contracts awarded by a public body, with the same bonding condition: 100% payment security and 100% performance security [4]. State procurement units and the Maryland Transportation Authority work under a parallel section, § 13-225 [5].

What the rule says

On a private job the ceiling operates twice over. Retention across the whole contract may not exceed 5% of the contract price, and retention from any single payment the owner makes to the contractor may not exceed 5% of that payment [1]. On a public job the test is the percentage the contract itself sets for retainage, which is capped at 5% of the contract's total amount [4]. Neither cap ends an owner's other rights to hold money: a private owner may still withhold amounts beyond retainage for reasonable grounds relating to performance [1], and a public body may still withhold additional amounts it reasonably believes necessary to protect its interest [4].

How to comply

Start with the bonding and, on a private job, the contract price, since the 5% ceiling is written for fully bonded contractors [1]. Then track who owes whom:

When private retention goes unpaid, there is no fixed statutory interest rate. Under Real Property § 9-303 a court may grant equitable relief for prompt payment of undisputed amounts, a term that expressly includes retention proceeds above the authorized amount, and may award interest from the date the amount was due plus reasonable costs [2]. A finding of bad faith opens the door to reasonable attorney's fees as well [2].
