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 Charles County.

For permits applied for on or after June 28, 2024, Charles County implements the 2021 International Building, Residential, Energy Conservation, Fuel Gas, Existing Building, Mechanical, Plumbing, Swimming Pool and Spa, Property Maintenance, and applicable portions of the Fire Codes, with county amendments, plus the 2020 National Electrical Code. Maryland State Fire Code, Maryland Building Rehabilitation Code, zoning, environmental, stormwater, and other applicable county requirements also apply.

Minor-work playbook

Understand what may be exempt—and what is not.

Examples of residential work not requiring a building permit include acid cleaning; air-conditioning repair or cleaning; residential awnings; kitchen cabinets; carpet, caulking, drywall, flagstone, floor-laying/refinishing, interior decoration, painting/plastering/paneling/paper hanging, tile, stucco, stained glass, and ornamental iron work; replacement of existing windows and doors in existing openings; fencing not over 7 feet (subject to zoning and Critical Area rules); furnace repair/cleaning without equipment replacement; like-for-like insulation work; lock/hardware replacement; oil-burner repair; pointing brick; like-for-like shingle or roll-roof replacement; sandblasting; siding replacement; sink/countertops; storm windows/doors/screens; extermination; and gutters/downspouts. This is not an all-inclusive list. Agricultural non-habitable outbuildings on verifiable agriculturally zoned parcels of at least five acres, qualifying open-sided temporary tents/membrane structures up to 2,400 square feet for under 180 days, and flagpoles no higher than 20 feet are also code exemptions; zoning permits may still apply.

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.

Inspection pipeline

Keep the work visible at every release point.

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 Charles County

Who handles permitting for this jurisdiction?

Charles County Department of Planning & Growth Management - Codes, Permits, and Inspection Services 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 301-645-0692.

How long might review take?

A submitted permit is processed for acceptance within 2 business days after receipt.

Additional reviews, missing documents, fees, or agency approvals can extend issuance.

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.
