Building permits in Baltimore, Maryland are issued by Baltimore City Department of Housing and Community Development for work in Baltimore City.
This guide covers what requires a permit, how to apply through E-Permits / ProjectDox or the correct local filing path, permit fees, trade permits, and inspections - so your Maryland project can move from submittal to approval with fewer correction cycles.
Confirm the authority having jurisdiction before filing. This guide is for projects in Baltimore City. Baltimore City DHCD processes permits online through E-Permits. Complex building projects may also use electronic plan review, and Baltimore City adopted local Building, Fire, and Related Codes that supplement the Maryland Building Performance Standards.
Maryland uses statewide performance standards with local enforcement. Maryland construction permitting is enforced locally, but local jurisdictions must use the Maryland Building Performance Standards (MBPS), based on the state-modified International Building Code, International Residential Code, International Energy Conservation Code, and related Maryland amendments. Local jurisdictions may adopt local amendments, while Maryland energy and accessibility requirements may be made more stringent but not less stringent.
Baltimore projects often involve historic districts, zoning, CHAP, fire, right-of-way, utilities, water service, use and occupancy, tenant improvements, rowhome alterations, and vacant-building issues. Start with address, parcel, and municipal boundary verification.
What requires a building permit in Baltimore?
Under Maryland building code requirements and local ordinances, a permit is required before most construction, alteration, demolition, repair, relocation, occupancy change, and trade work begins.
Permit required
- New residential and commercial construction, additions, remodels, shell buildings, and tenant improvements
- Structural changes, load-bearing work, foundations, decks, porches, stairs, garages, retaining walls, and accessory structures
- Electrical service changes, panels, generators, solar, EV chargers, new circuits, and most wiring
- Plumbing, water heaters, sewer and water connections, gas piping, backflow, and fixture relocations
- HVAC installations, replacements, ductwork, ventilation, kitchen hoods, fuel-gas appliances, and commercial equipment
- Roofing, siding, windows, signs, pools, fences, demolition, grading, sediment control, stormwater, fire protection, and right-of-way work where regulated
Typically exempt
- Painting, wallpaper, flooring, trim, cabinets, countertops, and similar finish work
- Minor repairs replacing existing materials in kind with no structural, electrical, plumbing, mechanical, fire, or occupancy change
- Small detached accessory structures below local thresholds when allowed by zoning and without utilities
- Temporary or portable equipment that the local code specifically exempts
Exemptions are narrow and local. Always verify with the permit office before starting work.
Get the permit before work begins. Starting without approval can lead to stop-work orders, double fees, correction orders, delayed occupancy, and problems with resale, financing, or insurance.

Baltimore trade permits
Trade permits are commonly required in addition to the building permit. Maryland state licensing, local contractor registration, and inspection requirements may apply depending on the scope and jurisdiction.
Electrical permits
Required for service upgrades, panels, new circuits, solar PV, EV chargers, generators, lighting retrofits, and most wiring work. Electrical contractors should verify Maryland licensing plus any local registration or master license requirements before permit filing.
Plumbing & gas permits
Required for new plumbing, fixture relocations, water heaters, sewer and water connections, backflow, gas piping, fuel-gas appliances, and private or public utility connections where applicable.
Mechanical / HVAC permits
Required for furnaces, boilers, AC units, heat pumps, ductwork, ventilation, commercial kitchen hoods, combustion air, exhaust, and major equipment replacements.
Fire, occupancy, and specialty permits
Commercial projects may require fire alarm, sprinkler, suppression, hood, hazardous-material, sign, demolition, grading, sediment control, stormwater, right-of-way, and certificate of occupancy approvals before final use.
Credential check: Maryland licensing depends on the work. Residential home improvement contractors are regulated by the Maryland Home Improvement Commission (MHIC). New home builders must follow Maryland home builder registration requirements, and electrical, plumbing, HVACR, fire protection, and other specialty trades may require state licenses plus local registration before permits or inspections can proceed.
