Howard County Basement Permit & Inspection Guide, July 2025

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

If you’re planning to finish or remodel your basement in Howard County, Maryland, securing the proper permits — and passing every inspection — isn’t optional, it’s required. The Howard County Department of Inspections, Licenses & Permits (DILP) enforces strict residential building codes to keep projects safe and up to standard. Skip a permit or miss an inspection, and you may face fines, stop-work orders, or the costly removal of completed work. This guide walks you through exactly which permits and licenses you’ll need, the inspection sequence (including Howard County’s plumbing + mechanical combo requirement), and how to keep your basement project on track.

Permits Required for Basement Finishing or Remodeling Projects in Howard County

Any basement project in Howard County typically calls for the permits below:

Permit	When It’s Required	Official Link
Building Permit	Framing, new walls, layout or structural changes, egress windows	Howard County Permits
Electrical Permit	New wiring, circuits, lighting, or panel upgrades	Electrical Permits
Plumbing Permit	Adding or relocating plumbing fixtures (toilets, sinks, showers, drains)	Plumbing Permits
Mechanical Permit	Any HVAC work — even ductwork-only modifications	Mechanical Permits
Fire Protection Permit	Only if you’re modifying an existing sprinkler system	Fire Protection Permit Form (PDF)

Apply online: Howard County’s ePermits portal lets licensed contractors submit applications, upload plans, and schedule inspections.

Licenses Required to Pull Permits in Howard County

Only properly licensed Maryland contractors can submit permit applications:

• Maryland Home Improvement Contractor (MHIC) License – required for the building permit.
  
  
• Master Electrician License – required for electrical permits.
  
  
• Master HVACR Contractor License – required for mechanical permits (HVAC work, even duct-only changes).
  
  
• Master Plumber License – required for plumbing permits.
  
  
• Fire-Protection Contractor License – required for sprinkler system modifications.
  
  

Working with licensed professionals helps prevent permit rejections, inspection failures, and liability issues later.

Basement Inspection Requirements in Howard County

Your permit is only the first step—passing inspections is what closes the job. Howard County follows this sequence:

1. Plumbing Groundwork Inspection
   Must be completed and approved before the slab or subfloor is closed up.
   
   
2. Rough-In Trade Inspections
   Electrical, plumbing, mechanical, and (if applicable) fire-protection rough-ins must be passed before any close-in building inspections are scheduled.

In Howard County, plumbing and mechanical (HVAC) rough-in inspections are often done at the same visit since both are handled by county inspectors – a convenient ‘two-in-one’ appointment. The same goes for final inspections of those trades, which can streamline your schedule.

1. Plumbing + Mechanical Combo Inspections (Close-In & Final)
   Howard County requires plumbing and mechanical close-in and final inspections to be scheduled together. Coordinate both trades so each is ready the same day.
   
   
2. Framing (Close-In) Building Inspection
   Conducted after all applicable rough-ins (including the plumbing + mechanical combo close-in) are passed and before insulation.
   
   
3. Insulation Inspection
   Must be passed before drywall installation.
   
   
4. Final Trade Inspections
   Electrical, plumbing, mechanical, and fire protection (if any) must each pass their final inspection before scheduling the final building inspection.
   
   
5. Final Building Inspection
   The last step—performed after all trade finals are approved.
   
   

Scheduling Flexibility: Except for the required plumbing + mechanical combo, inspections are conducted by different inspectors and do not need to be scheduled on the same day, giving you flexibility to phase the project.

Staying on top of this timeline (and the special combo rule) keeps your basement remodel moving and prevents costly re-inspections.
