Do You Need a Permit for Your Home Renovation in Montgomery County?

One of the most common questions we get from Silver Spring homeowners is: "Do I need a permit for this?" It is a fair question — permit requirements can feel confusing, and the consequences of skipping a required permit can be significant.

Here is a plain-language guide to permit requirements for home renovation work in Montgomery County.

Why Permits Matter

Permits exist to protect homeowners. When a permit is pulled and inspections are completed, a licensed inspector verifies that the work meets current building codes for structural integrity, electrical safety, fire protection, and plumbing. This protects you, your family, and future buyers of your home.

Unpermitted work creates real problems:

Selling your home — unpermitted work must be disclosed and can delay or kill a sale
Insurance claims — damage related to unpermitted work may not be covered
Safety — work done without inspection may have code violations that create hazards
Fines — Montgomery County can require unpermitted work to be opened up, inspected, and potentially redone at your expense

Work That Always Requires a Permit in Montgomery County

Any structural work (removing or modifying load-bearing walls, adding beams)
Electrical work beyond simple fixture replacement (new circuits, panel upgrades, subpanels)
Plumbing work beyond faucet replacement (new drain lines, moving supply lines, adding fixtures)
HVAC work (new systems, ductwork modifications, adding zones)
Additions of any size
Finishing a basement
Building a deck or porch
Installing a new roof (in most cases)
Converting a garage to living space
Adding or enlarging windows or doors in exterior walls

Work That Generally Does Not Require a Permit

Painting (interior or exterior)
Replacing flooring (carpet, hardwood, LVP) without structural changes
Replacing kitchen cabinets in the same location
Replacing countertops
Replacing fixtures (faucets, toilets, light fixtures) on existing supply/drain lines
Installing new appliances on existing circuits
Replacing windows or doors in the same opening (same size)
Landscaping and fencing (though fences have separate requirements)

The Gray Area: Kitchen and Bathroom Remodels

Kitchen and bathroom remodels often fall into a gray area because they can involve a mix of permitted and non-permitted work.

A cosmetic kitchen remodel — new cabinets, countertops, and appliances in the same locations — typically does not require a permit. But if you are moving the sink, adding an island with electrical, or changing the layout, permits are required.

A bathroom remodel that replaces fixtures in the same locations may not require a permit. But if you are moving the toilet, adding a shower where there was none, or reconfiguring the layout, permits are required.

When in doubt, pull the permit. The cost of a permit is small compared to the cost of problems down the road.

How the Permit Process Works

In Montgomery County, permits are obtained through the Department of Permitting Services (DPS). For most residential renovation projects, the process involves:

1. Submitting permit application with project description and drawings

2. Plan review (can take 2–6 weeks for complex projects)

3. Permit issuance

4. Work begins

5. Inspections at key stages (rough-in, framing, final)

6. Final approval and permit closure

For straightforward projects, Montgomery County offers an over-the-counter permit process that can be completed in a single visit.
