Contractor Payment Laws in Puerto Rico

Puerto Rico's contractor payment framework governs when and how general contractors, subcontractors, and suppliers must be paid on both private and public construction projects. These rules draw from Puerto Rico civil law traditions, the Commonwealth's own statutes, and federal requirements that apply when federal funds are involved. Understanding this framework is essential for any contractor operating in Puerto Rico, where payment disputes are among the most frequent sources of construction litigation and license complaints.

Definition and scope

Contractor payment laws in Puerto Rico establish legally enforceable timelines, conditions, and remedies related to compensation on construction projects. The framework covers three primary relationships: owner-to-general-contractor payments, general-contractor-to-subcontractor payments, and contractor-to-supplier payments.

The primary statutory authority governing private construction payment in Puerto Rico is found in Law No. 212 of August 12, 2018 (Ley de Subcontratistas), which specifically protects subcontractors and suppliers from delayed or withheld payment on private projects. For public construction, Law No. 73 of May 28, 1991 (Ley de Contratos de Obras Públicas) and its subsequent amendments establish payment obligations for government-funded construction contracts administered by agencies such as the Administración de Servicios Generales (ASG).

The scope of these laws extends to:

Projects funded through CDBG-DR allocations — significant in Puerto Rico following 2017 hurricane recovery — carry additional federal oversight, covered in detail on the Puerto Rico CDBG-DR Contractor Eligibility page.

How it works

Private projects operate under a pay-when-paid or pay-if-paid clause structure, but Puerto Rico courts have imposed limits on how broadly those clauses can shift risk downstream. Under Law No. 212 of 2018, once a general contractor receives payment from the owner, the contractor must transmit payment owed to subcontractors within 10 calendar days of receipt. Suppliers must be paid within the timeframe stipulated in the purchase order, but Law No. 212 imposes a backstop of 30 calendar days from invoice submission when no specific term is agreed upon.

Public projects follow a stricter schedule. Under Puerto Rico's public works statutes, government agencies must process contractor payment applications within 30 days of invoice certification. Interest accrues on late public payments at a rate set by the Puerto Rico Treasury Department (Departamento de Hacienda), and contractors may file claims directly with the contracting agency before escalating to the Court of First Instance.

For federally assisted projects, the federal Prompt Payment Act (31 U.S.C. § 3901) requires federal agencies to pay prime contractors within 30 days of a proper invoice. Prime contractors must then pay subcontractors within 7 days of receiving federal payment.

Retainage — the practice of withholding a percentage of each payment until project completion — is permitted in Puerto Rico but is subject to negotiated contract terms. On federally funded projects, retainage typically cannot exceed 10 percent of the contract value under standard federal acquisition guidelines.

The Puerto Rico mechanic lien laws provide contractors and suppliers with a security interest in the property when payment is withheld, functioning as the primary collection enforcement mechanism on private projects.

Common scenarios

Scenario 1 — Subcontractor non-payment on a private project: A specialty subcontractor completes electrical rough-in work and submits an invoice to the general contractor. The general contractor claims the owner has not yet paid. Under Law No. 212 of 2018, if the subcontract contains a pay-when-paid clause, that clause delays but does not eliminate the subcontractor's right to payment. After a reasonable period — interpreted by Puerto Rico courts as no more than 90 days absent extraordinary circumstances — the subcontractor may pursue lien rights or legal action independent of the general contractor's collection status.

Scenario 2 — Public works payment dispute: A general contractor on a Puerto Rico Department of Transportation project submits a change-order invoice that the agency disputes. The contractor must follow the administrative claims process under the agency's contract terms before seeking relief in the Court of First Instance. Failure to exhaust administrative remedies can bar a later lawsuit.

Scenario 3 — Federal disaster recovery project: On a FEMA or HUD-funded rebuild project, a subcontractor discovers the prime contractor has held funds for 45 days without disbursement. The subcontractor can report the violation to the federal agency's inspector general and to DACO. The prime contractor faces potential debarment from future federal contracting in addition to civil liability.

Decision boundaries

The choice of legal pathway depends on project type and the tier of the claimant:

  1. Private project, prime contractor vs. owner — Pursue contractual dispute resolution first; mechanic lien filing must occur within 180 days of last work performed under Puerto Rico lien law.
  2. Private project, subcontractor vs. general contractor — Law No. 212 of 2018 applies; lien rights are available regardless of pay-when-paid clauses after the statutory window expires.
  3. Public project, any tier — Administrative claims process is mandatory before judicial action; interest on late payments accrues automatically under statute.
  4. Federal project, subcontractor tier — Federal Prompt Payment Act subcontractor provisions apply; report to contracting agency and cognizant federal inspector general.
  5. Mixed-funding project (state + federal) — The more stringent standard governs each payment tier; federal timelines typically control.

Contractors navigating these distinctions should also review their obligations under Puerto Rico contractor subcontractor agreements and the broader compliance resources on the Puerto Rico Contractor Authority homepage.

For disputes that cannot be resolved through administrative channels, Puerto Rico contractor dispute resolution outlines arbitration, mediation, and litigation pathways available under Commonwealth law.
