State hub · MD
Maryland statutes affecting rooftop solar, low-impact and water-saving landscaping, and EV charging in common-interest communities.
This Maryland hub helps you find the state rule, local approval path, and property documents for a greener-home project. Choose a focused guide before you contact an HOA, landlord, permit office, utility, or incentive administrator.
A statewide answer can still depend on the city or county, the utility territory, the recorded declaration or lease, the ownership of a roof or parking space, the equipment configuration, and the effective date of the rule.
Before starting work, identify the local building, electrical, mechanical, fire, zoning, water, historic, or land-use office that has jurisdiction over the property. Ask the serving utility about service, metering, interconnection, or permission to operate. Review the governing documents, lease, contract, insurance, financing, and maintenance or restoration terms for the location.
Sometimes. Maryland Real Property § 2-119 protects a solar collector system on a roof or exterior wall that the property owner owns or has the right to use exclusively, but it allows an association to impose restrictions that are reasonable under the statute and gives an association broader authority over common areas and common elements. Historic-property and property-ownership facts can change the result.
