Baltimore Historic District Alteration Review

Land Use and Zoning Maryland 3 Minutes Read · published February 08, 2026 Flag of Maryland

Baltimore, Maryland preserves its historic neighborhoods through a local review process administered by the Commission for Historical & Architectural Preservation (CHAP)[1]. Property owners and contractors must follow rules for visible exterior work in designated historic districts and on landmarked buildings. This guide explains the review stages, typical timelines, responsible offices, enforcement and appeals, common violations, and practical action steps to prepare and submit applications.

Overview of the Review Process

The review begins with determining whether a property is within a designated historic district or individually designated as a landmark. Small routine repairs may be eligible for staff-level approval while major alterations usually require a public hearing and Commission decision.

  • Identify historic status and applicable guidelines.
  • Prepare drawings, photos and material specifications.
  • Submit application and pay any processing fee (see Applications & Forms).
  • Attend review or hearing if required; receive decision and any conditions.
Start early—pre-application review or informal staff advice can reduce delays.

Penalties & Enforcement

Enforcement responsibility for unauthorized work in Baltimore historic districts lies with CHAP and coordinating city departments. Exact civil fines, daily penalties, or escalation amounts are not specified on the cited page[1]. Where the code or CHAP rules set fees or fines, those amounts will appear in the municipal code or CHAP administrative materials.

  • Fine amounts: not specified on the cited page.
  • Escalation: first, repeat, and continuing offence ranges not specified on the cited page.
  • Non-monetary sanctions: stop-work orders, orders to restore, civil court actions, and injunctive relief are available remedies administered through CHAP or the city’s legal office.
  • Enforcer and complaint pathway: CHAP accepts complaints and coordinates inspections; contact CHAP for filing enforcement requests.
  • Appeals and review: statutory time limits for appeals are set in the governing ordinance or administrative rules; specific time periods are not specified on the cited page.
If work has already started without approval, contact CHAP immediately to discuss compliance and possible mitigation.

Applications & Forms

The primary application used for exterior changes is the Certificate/Permit application for historic properties; specific form names, numbers, fees, submission portals and filing deadlines are published by CHAP or the City Permit Center. Where a form or fee is not posted, the official CHAP or city permit pages must be consulted for current documents and filing instructions.

  • Application name: Certificate of Approval/Certificate of Appropriateness (title varies by program) - see CHAP for official form and submission method.
  • Fees: not specified on the cited page.
  • Submission: CHAP or the City Permit Center accepts applications; confirm electronic or in-person filing on the official page.
Always attach clear photographs and material samples to avoid delays at intake.

Common Violations

  • Exterior demolition or removal of character-defining features without approval.
  • Replacement of historic windows or doors with non-conforming modern units.
  • Unauthorized new construction or additions visible from the public right-of-way.
  • Failure to follow conditions of an approved permit or Certificate.

Action Steps

  • Confirm historic district or landmark status before planning work.
  • Gather photos, plans, and material specs for the application packet.
  • Submit the CHAP application and any permit forms through the City Permit Center.
  • If denied, file an appeal within the ordinance time frame or request reconsideration per CHAP rules.

FAQ

Do I always need CHAP approval for exterior alterations?
Not always; minor maintenance may be exempt, but work visible from the public right-of-way typically requires review—confirm with CHAP.
How long does review take?
Staff-level reviews are generally faster while applications requiring public hearing take longer; specific timelines depend on docket schedules and are posted by CHAP.
What if work was done without approval?
Contact CHAP promptly; the city may require restoration, a retroactive application, or other remedies.

How-To

  1. Confirm whether the property is in a historic district or is landmarked by consulting CHAP records.
  2. Assemble a complete application packet: photos, scaled drawings, and material samples.
  3. File the application with CHAP and pay any required processing fee through the City Permit Center.
  4. Attend any required hearing and be prepared to explain design choices and mitigation.
  5. If approved, obtain required permits before starting work; if denied, follow appeal steps or revise and resubmit.
Document decisions and retain a copy of the Certificate for future transactions and compliance checks.

Key Takeaways

  • Check historic status first to determine review requirements.
  • Complete application materials and early staff contact speed approval.
  • Unauthorized work can prompt orders to restore or other enforcement remedies.
