Signs and Advertising Maryland 3 Minutes Read · published February 08, 2026 Flag of Maryland

Baltimore, Maryland requires special review and permits for signs in locally designated historic districts to protect character and streetscape. This guide explains who reviews sign designs, how to apply, typical compliance requirements, enforcement pathways and practical action steps for property owners and businesses.

Overview of Historic District Sign Controls

Locally designated historic districts in Baltimore are subject to design review and sign standards intended to preserve architectural character. The City’s Commission for Historical and Architectural Preservation (CHAP) administers design review for signage in many historic districts; applicants normally must obtain CHAP approval before installing or altering signs in a district. CHAP design review[1]

Sign Design Standards

Design standards focus on sign scale, placement, materials, illumination and compatibility with the building and streetscape. Typical considerations include:

  • Size and proportion relative to the building facade
  • Mounting methods that avoid unnecessary damage to historic fabric
  • Lighting types and avoidance of excessive glare
  • Materials and colors that match the historic palette
Early contact with CHAP staff speeds review and reduces redesigns.

Permits, Review Process & Timeline

Two distinct reviews commonly apply: CHAP design review (for appropriateness in a historic district) and municipal permits for physical installation. Applicants should verify whether both approvals are necessary for a single project.

  • Apply for CHAP review with required drawings and materials samples.
  • CHAP public meetings or administrative reviews follow published schedules.
  • Obtain any City permits for sign installation from the permits portal.

For the City’s regulatory text and permit rules see the municipal code and permit portal. Baltimore City Code (municipal code)[2] and the City permits portal provide official procedures and submittal instructions. City permits portal[3]

Penalties & Enforcement

Enforcement is carried out by designated municipal enforcement units and may include fines, stop-work orders and orders to remove or alter non-compliant signs. Specific monetary penalties, escalation schedules and exact statutory citations must be confirmed in the municipal code or enforcement notices.

  • Fine amounts: not specified on the cited page.
  • Escalation for continuing offences: not specified on the cited page.
  • Non-monetary remedies: stop-work orders, removal orders and court enforcement are authorized; specific procedures are set by ordinance or administrative rule.
  • Enforcer and complaints: contact CHAP for historic review issues and the City permits/enforcement division via the official permits portal for compliance complaints.
If you receive an enforcement notice, follow the appeal steps immediately to avoid escalation.

Applications & Forms

CHAP requires a Certificate of Approval or similar application for work affecting historic resources; a separate municipal sign permit is often required for installation. Specific form names, numbers, fees and submission methods are available on CHAP and the City permits portal. If a precise fee or form number is not shown on the cited page, it is not specified on the cited page.

  • CHAP application: name and fee information are published by CHAP; see the CHAP design review page for the current application packet.[1]

Some CHAP reviews may be handled administratively without a public hearing.
