Permits & inspections in Montgomery County

The paperwork is the part most contractors gloss over.

A whole-home renovation usually needs a building permit plus separate electrical, plumbing and mechanical permits — each with its own inspection, each on its own timeline. Pulling them is not the hard part; sequencing them so no trade is standing around waiting for an inspector is.

Your Rockville permit goes through the Montgomery County Department of Permitting Services. We pull it under our license and we hold the inspection schedule — you do not chase inspectors and you do not sign the application.

Local to Rockville

Rockville is its own permitting jurisdiction. If your property sits inside the City of Rockville limits, the permit goes through the city — not Montgomery County DPS — and the two have separate submissions and separate inspectors. Getting that wrong at the start costs weeks, so we confirm which side of the line you are on before anything is filed.

What we find in Rockville homes

The house decides half the scope.

Rockville's stock runs from 1950s ramblers and split-levels in the older neighborhoods to newer townhome and infill construction. On the mid-century houses, expect to find undersized electrical service and cast-iron or galvanized supply lines once walls are open — both of which we price up front rather than as a surprise change order.

Who pulls the permit for a Rockville general contractor project?

We do, under our license, through the Montgomery County Department of Permitting Services. A whole-home renovation usually needs a building permit plus separate electrical, plumbing and mechanical permits — each with its own inspection, each on its own timeline. Pulling them is not the hard part; sequencing them so no trade is standing around waiting for an inspector is.

Is there anything specific to Rockville I should know?

Rockville is its own permitting jurisdiction. If your property sits inside the City of Rockville limits, the permit goes through the city — not Montgomery County DPS — and the two have separate submissions and separate inspectors. Getting that wrong at the start costs weeks, so we confirm which side of the line you are on before anything is filed.

What does general contractor cost in Rockville?

It depends entirely on scope, so we do not publish a single number. You get a written, line-item price after a free on-site walkthrough — not a verbal ballpark over the phone.

Is the Rockville walkthrough and estimate free?

Yes. The walkthrough and the written scope are free and yours to keep whether or not you hire us. There is no design fee and no consultation invoice.

Do I need a general contractor or can I hire trades directly?

You can hire trades directly, and for a single-trade job that is often cheaper. It stops being cheaper the moment two trades have to be sequenced around an inspection — someone has to own that schedule, and if it is not a contractor it is you. A licensed GC also carries the permit and the liability.
