Baltimore City E-Permits
The City of Baltimore issues building permits through E-Permits, the online system run by the city's Department of Housing and Community Development (DHCD). Residential and commercial construction, interior and exterior alterations, electrical, mechanical and plumbing work, and use-and-occupancy permits are all applied for, paid, and tracked there, and the city staffs an in-person kiosk at 417 E Fayette St for applicants who want help filing.
Every permit DHCD issues through E-Permits is public record, and the counts and trends on this page are built from that same public permit activity for the City of Baltimore. To apply for a permit or check the status of one, start at the E-Permits portal.
