Payment-in-Lieu under Boston Inclusionary Rules

Land Use and Zoning Massachusetts 3 Minutes Read ยท published February 07, 2026 Flag of Massachusetts

Boston, Massachusetts requires many new residential developments to address affordable housing through inclusionary requirements. This guide explains Payment-in-Lieu (PIL) options under the city and BPDA inclusionary framework, how PIL is calculated and collected, enforcement and appeals, and practical steps developers and residents must follow to comply.

Overview of Payment-in-Lieu Options

Under Boston's Inclusionary Development Policy developers may provide on-site affordable units, off-site units, or a Payment-in-Lieu contribution where allowed by the policy. The BPDA maintains the Inclusionary Development Policy and project review procedures; see the policy for scope and triggers Boston Inclusionary Development Policy[1].

Confirm early in project review whether a PIL option is permitted for your proposal.

Penalties & Enforcement

Enforcement of inclusionary obligations and PIL payments is administered through the BPDA project review process and recorded through agreements or covenants tied to building permits and certificates of occupancy. Specific fine amounts and daily penalties are not specified on the cited policy page[1].

  • Monetary fines: not specified on the cited page; monetary remedies are implemented through recorded agreements or compliance covenants[1].
  • Escalation: first, repeat, or continuing offence escalation ranges are not specified on the cited page and are enforced via project-specific agreements or legal action where needed[1].
  • Non-monetary sanctions: covenant enforcement, stop-work or withholding of certificates of occupancy, injunctions, and court actions may be used; specific remedies are governed by recorded agreements and applicable city procedures.
  • Enforcer and complaints: the Boston Planning & Development Agency (BPDA) administers IDP compliance and accepts inquiries and complaints through its project review and contact pages[1].
  • Appeals and review: appeals of BPDA determinations follow the agency's project review and administrative appeal processes; time limits for appeals are set in the underlying approvals or agreements and are not specified on the cited page.
Recorded compliance agreements are the primary enforcement tool for PIL obligations.

Applications & Forms

The BPDA project review and Inclusionary Development Policy pages explain requirements; there is no single standardized city PIL payment form published on the IDP policy page and specific payment instructions are set in project-level agreements or closing documents[1].

How PIL Amounts are Determined

PIL amounts are typically calculated to approximate the value of providing an affordable unit on-site. The IDP provides methodology principles, but exact per-unit dollar figures or fee tables are not specified on the cited policy page and are determined in project review or by administrative guidance[1].

  • Timing: payment schedules are negotiated in project agreements and recorded against permits or covenants.
  • Documentation: PIL obligations are documented in development agreements, mitigation agreements, or covenants recorded with the Registry.
  • Monitoring: compliance monitoring is conducted by BPDA or its designee per the recorded agreement.
PIL may only be available where the IDP or project approvals allow it by exception or negotiation.

Action Steps for Developers

  • Confirm IDP applicability at pre-submission and during BPDA project review.
  • Propose on-site, off-site, or PIL options in the community and design review package.
  • Negotiate payment schedule and record required agreements before permit issuance.
  • Secure evidence of recorded covenants or agreements before certificate of occupancy is granted.
