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 Anne Arundel County.

Current for 2026: 2021 International Building Code, 2021 International Residential Code, 2021 International Energy Conservation Code, 2021 International Existing Building Code, 2021 International Swimming Pool and Spa Code, 2020 National Electrical Code, 2021 International Fuel Gas Code, 2021 International Mechanical Code, and 2021 International Plumbing Code.

Inspection lane

Schedule and track inspections in the Land Use Navigator after the permit has been active for at least 24 hours. Approved drawings and grading plans must be onsite. Trade finals must be complete before the final building inspection; for commercial or tenant-improvement work, the Fire Marshal life-safety final must also pass first. If internet scheduling is unavailable, call 410-222-7784 and listen for the dispatcher Monday-Friday, 7:30 a.m.-4:00 p.m.; Building Inspections can be reached at 410-222-7790.

Minor-work playbook

Understand what may be exempt—and what is not.

The county's project guide identifies limited exemptions: ground-level residential patios generally do not require a building permit, though grading approval may be required; detached residential decks under 200 square feet and under 3 feet high may be exempt outside the Critical Area or Bog Contribution Drainage Area; replacing roof shingles only does not require a permit; replacing or reinstalling solar panels in kind does not require a building permit, but electrical authorization may be required; detached sheds or gazebos no larger than 150 square feet and no higher than 10 feet may be exempt outside the Critical Area; and residential pools require permits only when in-ground or above-ground over 36 inches. Fences, retaining walls, decks, additions, alterations, new structures, and most commercial work generally require permits, with location and scope controlling.

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

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 Anne Arundel County

Who handles permitting for this jurisdiction?

Anne Arundel County Department of Inspections and Permits 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 410-222-7730 (Permit Center); 410-222-4432 (inspection scheduling questions); 410-222-7790 (Building Inspections).

How long might review take?

Typical review for a non-residential tenant-improvement permit is approximately 10 business days for each submittal after acceptance; other permit timelines vary by project and agency reviews. The county's system help notes that manager review remaining for more than five business days should be referred to the Permit Center.

How are inspections scheduled?

Schedule and track inspections in the Land Use Navigator after the permit has been active for at least 24 hours. Approved drawings and grading plans must be onsite. Trade finals must be complete before the final building inspection; for commercial or tenant-improvement work, the Fire Marshal life-safety final must also pass first. If internet scheduling is unavailable, call 410-222-7784 and listen for the dispatcher Monday-Friday, 7:30 a.m.-4:00 p.m.; Building Inspections can be reached at 410-222-7790.

Which codes and exemptions should I review?

Current for 2026: 2021 International Building Code, 2021 International Residential Code, 2021 International Energy Conservation Code, 2021 International Existing Building Code, 2021 International Swimming Pool and Spa Code, 2020 National Electrical Code, 2021 International Fuel Gas Code, 2021 International Mechanical Code, and 2021 International Plumbing Code. The county's 2024 code package is effective June 23, 2024; 2024 NFPA 1 Uniform Fire Code and 2024 NFPA 101 Life Safety Code amendments under Bill 13-26 are effective May 25, 2026.

Fences, retaining walls, decks, additions, alterations, new structures, and most commercial work generally require permits, with location and scope controlling.

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.
