Thinking of Remodeling Your Basement in Washington County, MD? Start Here.

If you're planning to finish or remodel your basement in Washington County, Maryland, securing the proper permits and passing required inspections is non-negotiable. The Washington County Division of Permits and Inspections enforces state and county codes to ensure that all remodeling work - especially basement conversions - is completed safely and legally. Unpermitted work can result in stop-work orders, expensive rework, or delays in selling your home. This guide will walk you through everything you need to know to stay compliant from start to final inspection.

Permits Required for Basement Remodeling Projects in Washington County

In Washington County, most basement finishing and remodeling jobs require multiple permits based on the scope of your project. These may include:

Building Permit – Required for any structural changes such as framing, layout adjustments, cutting into foundation walls for egress windows, or changes to insulation and drywall. Apply online via the Washington County Permit Portal.
Electrical Permit – Needed if you're installing new lighting, outlets, or making updates to the existing wiring or electrical panel. A licensed Master Electrician must apply—verify licensing through the Maryland Department of Labor.
Plumbing Permit – Triggered by adding or moving any plumbing fixtures, such as a bathroom, sink, or wet bar. Licensing is handled by Maryland Plumbing Board.
Mechanical Permit – Required for any HVAC work, including duct modifications, system replacement, or adding new vents or returns. Your HVAC contractor must be licensed per Maryland HVACR license rules.
Fire Protection Permit – Required only if your basement includes a fire sprinkler system and modifications are planned. Fire sprinkler contractors must be certified - view license application form here.

To apply, use Washington County’s online Washington County Permit Portal for electronic submissions and real-time updates.

Inspection Requirements in Washington County, MD

Getting your permits is only step one—passing inspections is just as crucial. In Washington County, inspections follow a clearly defined order:

Plumbing Groundwork – Must be completed and inspected before the slab is poured or flooring is closed up. This step is critical if you're adding a bathroom or bar.
Rough-in Inspections – Electrical, mechanical, and plumbing rough-ins must be approved before framing and insulation. This ensures all hidden work is safe and up to code.
Framing/Building Inspection – Scheduled after all trade rough-ins pass. Ensures framing meets structural and egress requirements.
Insulation Inspection – Performed after framing, but before drywall installation.
Final Inspections – Each trade (electrical, plumbing, HVAC) must pass a final inspection. Only after all trade finals are complete can you schedule the Final Building Inspection.

Washington County typically assigns separate inspectors for each trade, and inspections can often be scheduled independently to accommodate project timelines. This flexibility helps avoid bottlenecks when one trade isn't quite ready.

We coordinate all required inspections so you don’t have to worry about timelines or compliance. See how we handle it.
