HOA Restrictions
HOA Restrictions on Solar in Baltimore: Maryland has no statewide law preventing HOAs from restricting solar panels. HOA covenants may restrict visible solar installations in planned communities. Baltimore's older rowhouse neighborhoods typically have no HOAs. Planned communities in newer parts of Baltimore City may have HOA restrictions.
Permit Process

Maryland net metering law requires utilities to credit excess solar generation at retail rate. Maryland Clean Energy Incentive Act and federal ITC support solar installations. Baltimore rowhouses often have good south-facing roof exposure on rear slopes.
Historic District Considerations
Historic District Considerations in Baltimore: Baltimore has extensive historic district designations covering Fells Point, Federal Hill, Roland Park, Reservoir Hill, and numerous other neighborhoods. Baltimore's Commission for Historical and Architectural Preservation (CHAP) reviews exterior changes including solar installations visible from public rights-of-way in locally designated districts. Rear-facing panel installations on rowhouses typically proceed without CHAP review. If your property is located in a historic district, contact the Baltimore City Department of Planning before designing your solar system — placement restrictions may affect system output.
Frequently Asked Questions
Is Baltimore City the same as Baltimore County?
No — they are completely separate jurisdictions. Baltimore City is an independent city and not part of Baltimore County. Baltimore County is a separate county government that surrounds the city. If your property is in Baltimore City, it is governed by Baltimore City agencies, codes, and regulations. Baltimore County properties use Baltimore County's separate permitting, zoning, and planning departments. This is a common source of confusion for newcomers to Maryland.
Can I build an ADU or convert my carriage house in Baltimore City?
Yes — Baltimore City allows accessory dwelling units. Many Baltimore properties have rear carriage houses (built in the 19th-early 20th century) that are excellent candidates for ADU conversion. You'll need a building permit from DHCD. No owner-occupancy requirement, no parking required, and no significant impact fees. Baltimore DHCD has programs that may provide financial assistance for eligible ADU projects as part of the city's housing strategy.
What are Baltimore's rules for short-term rentals?
Baltimore requires a Short-Term Residential Rental License ($200/year). An inspection is required before the license is issued. Maximum occupancy is 2 persons per bedroom and you need 24/7 emergency contact availability. Maryland state sales tax plus Baltimore City hotel rental tax apply — STR platforms collect and remit these taxes. Baltimore has a robust STR market given its proximity to DC, the Inner Harbor, and major universities.
My Baltimore home was built before 1978 — what should I know about lead paint?
Baltimore has significant lead paint issues in its older housing stock. Maryland's Lead Poisoning Prevention Program has specific requirements for pre-1978 rental properties. If you're doing renovation, you must follow EPA's Renovation, Repair, and Painting (RRP) Rule for lead-safe work practices. Rental properties must be registered with the Maryland Department of the Environment and pass periodic lead inspections. Baltimore City has additional lead abatement requirements and resources through DHCD.
How does Baltimore's CHAP historic preservation review work?
Baltimore's Commission for Historical and Architectural Preservation (CHAP) reviews exterior changes to contributing structures in 22+ locally designated historic districts and portions of National Register Historic Districts. If your property is in a CHAP district, you must obtain a Certificate of Approval (CoA) before making exterior changes — including window replacement, door changes, siding, and additions. Interior changes don't require CHAP review. CHAP meetings are held monthly and most straightforward applications are approved administratively.
Are there programs to help renovate vacant Baltimore rowhouses?
Yes — Baltimore DHCD operates several programs targeting vacant properties including the Baltimore Housing Rehab Program, Vacants to Value (V2V) initiative, and Homeownership Incentive Program. Baltimore City Land Bank manages a portfolio of city-owned vacant properties for sale to developers and owner-occupants. These programs prioritize neighborhoods experiencing revitalization like Remington, Oliver, Greektown, and Cherry Hill. Contact DHCD at dhcd.baltimorecity.gov for current program availability.
