Deck Building in Gaithersburg, MD — Custom Deck Contractor for Kentlands, Crown Farm & All Neighborhoods
Deck Building Services in Gaithersburg, MD
Types of Decks We Build in Gaithersburg
Gaithersburg's housing spans early 20th century bungalows in the historic city core, 1990s–2000s Kentlands and Lakelands townhomes and single-family homes, 2000s–2010s Crown Farm colonials, and everything in between. Here is what we build most commonly:
Composite Rear Deck — HOA Compliant
The most popular deck type in Gaithersburg's planned communities. Trex or TimberTech composite in colors approved by the Kentlands or Lakelands ARC — typically warm earth tones or greys that complement the community's architectural palette. Built to the specific dimensions that fit within the rear yard setbacks of Kentlands and Lakelands lots — which are more constrained than typical suburban lots given the new urbanist street-front orientation of these communities. ARC documentation, approval management, and City permit filing all included.
Multi-Level Composite Deck
Crown Farm's 2000s–2010s colonials often have larger rear yards and rear-loaded garages — creating more usable rear yard space for multi-level deck builds than is available in Kentlands' front-porch-focused layout. A two-level composite deck with upper dining area and lower grilling zone suits Crown Farm's colonial housing well. Crown Farm HOA ARC approval required before Montgomery County DPS permit filing. DMV-GC Group manages both processes in-house.
Pressure-Treated or Cedar Rear Deck
For Gaithersburg's older established residential neighborhoods near the historic city center — Washington Grove adjacent areas, older streets off Md-355 — a traditional pressure-treated or cedar deck is often the most appropriate and cost-effective choice. These neighborhoods have less HOA governance and more design latitude. City of Gaithersburg DPW permits required for properties within the city limits; Montgomery County DPS for those outside. DMV-GC Group verifies jurisdiction before filing.
Deck with Outdoor Kitchen & Pergola
A fully integrated outdoor living build — composite or hardwood deck with built-in outdoor kitchen, shade pergola, and lighting — for Gaithersburg homeowners who want a complete outdoor room. Crown Farm and Washingtonian Woods larger-lot properties are the most common candidates for this scope in Gaithersburg. Gas line, plumbing, and electrical all managed by in-house licensed trades — one contract. HOA ARC approval and City or County permit filing included.
City of Gaithersburg vs Montgomery County — Which Permit Authority Governs Your Deck
This is the most important practical question for any Gaithersburg deck project. The answer depends on your specific parcel's location — not your mailing address, and not proximity to a neighbor who filed with one authority or the other.

- MoCo COO required before deck occupancy
HOA Architectural Review in Gaithersburg — Kentlands, Lakelands, Crown Farm & Washingtonian Woods
Independent of which government issues the building permit, many of Gaithersburg's planned communities require HOA Architectural Review Committee approval before any exterior modification — including deck construction — is permitted. This is a separate process from the building permit and must typically be completed before the permit is filed. DMV-GC Group manages both processes simultaneously wherever the HOA allows.
Kentlands
Kentlands' HOA has an active Architectural Review Committee that reviews all exterior modifications. Deck ARC submissions require site plan, elevation drawings, material specifications, and color samples. Kentlands ARC design standards reflect the community's new urbanist aesthetic — rear yard decks must be compatible in scale and material with the home's existing character and neighboring properties. City of Gaithersburg DPW permit required after ARC approval. DMV-GC Group prepares all ARC documentation and designs to Kentlands standards from the first draft.
Lakelands
Lakelands shares Kentlands' new urbanist design philosophy and has its own HOA with ARC review for exterior modifications including decks. Rear yard deck construction requires Lakelands ARC approval before City of Gaithersburg DPW permits are filed. ARC review considers the deck's scale, materials, colors, and compatibility with the home's architecture. DMV-GC Group manages Lakelands ARC submissions in-house with full documentation prepared for first-round approval.
Crown Farm
Crown Farm's HOA also requires ARC approval for deck construction — even though Crown Farm uses Montgomery County DPS permits rather than City of Gaithersburg permits. This is a common source of confusion: the permit authority is the county, but the HOA review is Crown Farm's own. DMV-GC Group manages Crown Farm ARC submissions and Montgomery County permit filings in-house — both processes handled simultaneously where timing allows.
Washingtonian Woods
Washingtonian Woods has an active HOA with ARC review for exterior modifications. The permit jurisdiction for specific Washingtonian Woods addresses should be verified by parcel — some addresses are within City limits (City permit), others are unincorporated (MoCo permit). DMV-GC Group verifies both jurisdiction and HOA requirements for every Washingtonian Woods address before any work begins.
📋 What DMV-GC Group Prepares for Gaithersburg HOA ARC Submissions
- Site plan: Survey-based plot plan showing the home footprint, property lines, existing structures, and proposed deck location with dimensions — required by all four Gaithersburg HOAs for deck ARC submissions.
- Elevation drawings: Front, side, and rear elevation drawings showing the deck's height relative to the home and ground, railing style, stair location, and visual relationship to the home's existing exterior. Prepared to ARC submission standards.
- Material and color specifications: Manufacturer name, product line, SKU, and color swatch for all deck surface, railing, and post materials — required by Kentlands and Lakelands ARC to verify compatibility with community design standards.
- Parallel permit preparation: While ARC review is underway, DMV-GC Group prepares the City or County building permit application — so that the permit can be filed the same day ARC approval is received, minimizing total pre-construction timeline.
- ARC revision management: If the ARC requests modifications to the design, DMV-GC Group prepares and resubmits the revised documentation — no additional charge for first-round revision responses.

What Gaithersburg Homeowners Say About DMV-GC Group
"Our Kentlands home required HOA ARC approval before the City permit. DMV-GC Group prepared the entire ARC submission — site plan, elevations, material specs — and it was approved on the first review. The composite deck they built in Trex Tiki Torch is exactly what the ARC approved and exactly what we wanted."
"We were confused about whether Crown Farm uses City or County permits. DMV-GC Group confirmed immediately it was Montgomery County — not City of Gaithersburg — and filed with MoCo DPS. The Crown Farm HOA ARC and the MoCo permit were both managed by their team. Our two-level TimberTech deck is outstanding."
"We wanted a pergola with our Lakelands deck. DMV-GC Group designed the pergola to match our home's craftsman trim details — the ARC approved it without revision. The City of Gaithersburg permit came through two weeks after ARC approval. We were on the deck with guests the same month we'd hoped."
"Our Washingtonian Woods home needed both HOA approval and a building permit — and nobody could agree on whether it was City or County. DMV-GC Group checked the parcel data, confirmed it was City jurisdiction, managed both submissions, and built us a beautiful composite deck with outdoor kitchen. Complete project, zero headaches on our end."
