Maryland enacted HB 538 in 2024 (Land Use - Affordable Housing - Zoning Density and Permitting). The act restricts local prohibitions on manufactured and modular dwellings in single-family districts and requires increased density for certain qualified affordable projects. It is not an ADU preemption mandate.

Baltimore City was separated from Baltimore County by an amendment to the Maryland Constitution in 1851, making it an independent city. It has its own zoning code, planning department, and permit process, entirely separate from Baltimore County (seat Towson). This is unusual in the United States - only a handful of cities, most in Virginia, have similar independent-city status.

Key Zoning Facts
Baltimore Zoning Overview
Baltimore is a city in Maryland that manages land use and development through its local zoning ordinance. The city's zoning code divides the municipality into districts that regulate the types of uses permitted, building heights, lot sizes, setbacks, and density. Residents and developers should consult the city's planning department and municipal code for the most current zoning regulations and requirements.
The city's zoning ordinance typically includes residential, commercial, industrial, and mixed-use districts, each with specific development standards. Residential districts range from low-density single-family zones to higher-density multi-family zones. Commercial districts accommodate retail, office, and service uses, while industrial districts are designated for manufacturing and warehousing operations.
Development Process
Development in Baltimore generally requires obtaining the appropriate permits from the city's planning and building departments. The process typically involves:
- Zoning Verification — Confirm that your proposed use is permitted in the applicable zoning district
- Site Plan Review — For commercial and multi-family projects, submit a site plan for review
- Building Permit — Apply for a building permit with construction documents
- Inspections — Schedule required inspections during construction
- Certificate of Occupancy — Obtain final approval before occupying the structure
For projects that do not conform to existing zoning, property owners may need to seek a variance, special exception, or rezoning through the local board of zoning appeals or planning commission.
Key Considerations
Before starting any development project in Baltimore, property owners should:
- Verify the zoning classification of their property
- Review setback, height, and lot coverage requirements
- Check for any overlay districts or special regulations
- Determine if the property is in a flood zone using FEMA's flood map service
- Confirm whether HOA covenants or deed restrictions apply
- Contact the planning department for pre-application guidance
