Codes, exemptions & field inspections

Build to the adopted code. Verify every exception.

This guide translates the available agency record into a preconstruction checklist for structural scope, minor work, and inspection release. The adopted code and the issuing official control when a field condition is disputed.

Regulatory framework

The code baseline for Baltimore City County.

Baltimore City adopted the 2021 International Building Code and 2021 International Residential Code with City modifications. Related adopted standards include the 2020 National Electrical Code and 2021 International Fuel Gas, Mechanical, Plumbing, Property Maintenance, Fire, Energy Conservation, Green Construction, and Swimming Pool and Spa Codes, together with Maryland Building Performance Standards, accessibility, floodplain, preservation, and zoning requirements.

Inspection lane

Schedule inspections through the E-Permits account or by searching the permit record, with the city's scheduling cutoff at 2:30 p.m. on the day before the requested date. All permits require inspections and a final inspection before a Certificate of Occupancy. Typical stages include footing, foundation, slab, framing, insulation, trade rough-in, and final; call Building Inspections at 410-396-3470, Fire at 410-396-5752/5753, or Health at 410-396-4544/4424 as applicable.

Minor-work playbook

Understand what may be exempt—and what is not.

The city code exempts, subject to all other laws and historic-preservation rules, interior painting, papering, tiling, carpeting, cabinets, countertops and similar interior finish work; minor drywall or plaster patching; replacing roof shingles or roof tarring; debris removal that is not demolition; boarding exterior openings with plywood; qualifying agricultural hoophouses without service systems; and other limited IRC/IBC exemptions. An exemption does not authorize code-violating work, and exterior or historic-district work may still require approval.

Field rule

A permit exemption generally addresses one narrow construction trigger. It does not automatically waive zoning, land-use, floodplain, shoreline, fire, energy, electrical, utility, septic, or right-of-way requirements. Obtain written confirmation when the project involves a new structure, structural alteration, change in occupancy, or concealed work.

Contractor verification

Verify the builder before the contract is signed.

Use the state licensing system to verify active registration, trade credentials, bond status, and liability coverage where available. Match the legal business name to the proposal and permit application.

Planning reference

Keep the parcel rules beside the building plans.

A building permit is only one part of statutory compliance. Check the local zoning, ordinance, map, or land-use reference before finalizing setbacks, height, lot coverage, access, drainage, or accessory structure placement.

Project questions

Frequently asked questions for Baltimore City

Who handles permitting for this jurisdiction?

City of Baltimore Department of Housing and Community Development – Office of Permits and Building Inspections is the identified county-level authority for this profile. Confirm that the property is in its service area before filing.

How should I begin an application?

Begin with the online permit gateway listed in the application guide. If the portal does not recognize the address or project type, contact 443-984-1809 (permit information); 410-396-3470 (building, electrical, mechanical, and plumbing inspections).

How long might review take?

Most permit applications that do not require plans are issued in under one hour at the One Stop Shop; the city states that more than 98% of applications submitted with plans are reviewed in less than 30 days. Fast Track may be available for qualifying projects.

How are inspections scheduled?

Schedule inspections through the E-Permits account or by searching the permit record, with the city's scheduling cutoff at 2:30 p.m. on the day before the requested date. All permits require inspections and a final inspection before a Certificate of Occupancy. Typical stages include footing, foundation, slab, framing, insulation, trade rough-in, and final; call Building Inspections at 410-396-3470, Fire at 410-396-5752/5753, or Health at 410-396-4544/4424 as applicable.

Which codes and exemptions should I review?

Baltimore City adopted the 2021 International Building Code and 2021 International Residential Code with City modifications. Related adopted standards include the 2020 National Electrical Code and 2021 International Fuel Gas, Mechanical, Plumbing, Property Maintenance, Fire, Energy Conservation, Green Construction, and Swimming Pool and Spa Codes, together with Maryland Building Performance Standards, accessibility, floodplain, preservation, and zoning requirements. The city code exempts, subject to all other laws and historic-preservation rules, interior painting, papering, tiling, carpeting, cabinets, countertops and similar interior finish work; minor drywall or plaster patching; replacing roof shingles or roof tarring; debris removal that is not demolition; boarding exterior openings with plywood; qualifying agricultural hoophouses without service systems; and other limited IRC/IBC exemptions. An exemption does not authorize code-violating work, and exterior or historic-district work may still require approval.

Field sequencing matters

The inspector needs to see the work at the right moment.

Code compliance is not only a plan-review exercise. Footings, reinforcement, framing, fireblocking, wiring, piping, insulation, weather protection, and life-safety systems each have points where the work must remain accessible. Build the inspection calendar into the trade schedule instead of treating it as a final administrative step.

When a project qualifies for a narrow minor-work exemption, keep a written explanation of why it qualifies and confirm that related zoning, utility, fire, energy, or environmental rules do not create a separate approval requirement.

Closeout file

Keep the approved plan set, inspection approvals, correction responses, contractor license verification, final certificate, and any occupancy release together. A clean record protects the owner, builder, lender, insurer, and future buyer.
