Baltimore County Basement Permit & Inspection Guide, July 2025

Planning a Basement Remodel in Baltimore County, MD? Start Here.

If you're finishing or remodeling your basement in Baltimore County, MD, you’ll need to follow the county’s permitting and inspection process to ensure everything is done legally and safely. Baltimore County enforces residential construction codes that require permits for structural, electrical, plumbing, and mechanical work. Skipping permits or failing inspections can lead to fines, stop work orders, and expensive rework.

This guide outlines the exact permits you need, which inspections to expect, and how to stay compliant throughout your basement renovation—plus how BasementRemodeling.com makes it all easier.

Permits Required for Basement Finishing or Basement Remodeling Projects in Baltimore County, Maryland

Basement remodeling in Baltimore County typically requires several types of permits, depending on the scope of work. Here are the most common:

  • Building Permit – Required only if you’re adding a bedroom or making structural changes such as structural framing, moving structural walls, or installing egress windows.

  • Electrical Permit – Needed for new outlets, lighting, circuit panels, or any wiring upgrades.

  • Plumbing Permit – Mandatory if you're adding or modifying plumbing fixtures like toilets, sinks, or floor drains.

  • Mechanical Permit – Only required if you’re installing or modifying HVAC systems (heating, cooling, or ventilation).

  • Fire Protection Permit – May be required only if your basement has an existing sprinkler system that is being modified.

Baltimore County offers an online portal to apply for permits via the Accela Citizen Access System. You can also review permit guidelines on the Permits & Approvals Overview.

We work only with fully licensed professionals to ensure every aspect of your basement remodel—from framing to finish—is up to code and legally approved.

Inspection Requirements for Remodeling and Finishing a Basement in Baltimore County

Baltimore County requires a series of inspections to verify that permitted work complies with safety and building standards. Here's the typical sequence:

    • Plumbing groundwork inspection – Must be passed before covering flooring.

    • Trade inspections – Electrical, plumbing, mechanical, and fire protection must be completed before moving on to building (framing, insulation and final)  inspections.

    • Insulation inspection – Required before installing drywall or enclosing framed walls.

    • Final building inspection – This is your project’s last checkpoint before it’s approved.

  • Please note, building inspections are only required if there is a building permit on the project.

 

Each inspection is performed by a specialized inspector and doesn't need to be scheduled on the same day. Baltimore County often schedules combination inspections for close-in or final stages, allowing multiple trades to be approved during a single visit.

BasementRemodeling.com handles all scheduling and coordination to help your project move forward without delays. Here’s how our process works.
