Gaithersburg's Two Housing Eras — Different Electrical Needs
🏘️ Kentlands, Lakelands & Planned Communities (1988–2010s) — Modern Stock, Modern Upgrades
- Built with 200A service as standard — adequate baseline for most household loads
- Most common upgrade: EV charger — dedicated 240V circuit; panel capacity usually supports one charger without upgrade
- 400A upgrade when two EVs + heat pump + garage workshop push beyond 200A capacity
- Smart home wiring — Lutron, Leviton, and home automation increasingly common in this community
- Standby generator — popular in Kentlands; HOA ARC placement requirements confirmed before permit filing
- Permit: City of Gaithersburg DPW — not MoCo DPS
🏚️ Older Gaithersburg Homes (Pre-1985) — Mid-Century Electrical Conditions
- 100A panels common — undersized for today's EV chargers, heat pumps, and modern kitchens
- Federal Pacific panels — found in Gaithersburg homes built or updated 1960–1982; fire hazard requiring replacement
- Aluminum branch circuit wiring — homes built 1965–1973; assessed at every free estimate for this vintage
- GFCI protection absent — kitchens, bathrooms, and garages in pre-1985 homes frequently lack required GFCI protection
- Permit: MoCo DPS or City DPW — depends on location; confirmed by parcel
EV Charger Installation in Gaithersburg — Kentlands, Crown Farm & All Communities
🚗 Gaithersburg's planned communities have among the highest EV adoption rates in Montgomery County — and Level 2 home charging is now the standard expectation for Gaithersburg homeowners. For Kentlands and Lakelands homes built with 200A service, a single EV charger installation is typically straightforward — the panel has capacity and the dedicated 50A circuit runs to the attached garage. For homes with two EVs or an EV plus a heat pump, a 400A service upgrade may be warranted to avoid chronic load conflicts. For older Gaithersburg homes on 100A service, panel upgrade is typically the first step before EV charger installation can be properly supported. DMV General Contracting Group assesses panel capacity at the free estimate for every Gaithersburg EV project and quotes the full scope — charger plus any needed panel upgrade — together.
Standby Generator Installation in Gaithersburg — HOA Requirements in Kentlands
🏘️ Kentlands ARC & Generator Placement — Confirmed Before Any Permit Is Filed
The Kentlands Community Association's Architectural Review Committee governs exterior modifications in the community — and standby generator installation, which involves a permanent exterior concrete pad, visible equipment, and an audible engine, is subject to ARC review in many Kentlands situations. Typical ARC considerations include generator placement relative to property lines and neighboring homes, screening or enclosure requirements, and noise level compliance. DMV General Contracting Group confirms Kentlands ARC requirements for generator placement at the free consultation — designing the pad location and any required screening to satisfy ARC standards before any permit is filed with the City of Gaithersburg DPW. We have installed generators in Kentlands and are familiar with the community's generator review process. For Crown Farm and other MoCo DPS communities, we confirm HOA requirements at the consultation and manage any required submissions before filing with MoCo DPS.

Our Electrical Service Process in Gaithersburg
Free In-Home Assessment — Jurisdiction Confirmed, Panel & Needs Assessed
We visit your Gaithersburg home and begin by confirming your permit jurisdiction — City of Gaithersburg DPW or MoCo DPS — by parcel before any electrical discussion begins. We then assess your panel size and brand, outlet grounding, planned electrical additions (EV charger, generator, smart home, renovation), and HOA requirements for any exterior work. For Kentlands and Lakelands, we note ARC requirements for generators. For older Gaithersburg homes, we check for Federal Pacific panels and aluminum wiring. Detailed written estimate at no charge, no obligation.
HOA ARC Confirmation (Kentlands & Other Communities Where Required)
For generator installations in Kentlands and other HOA communities, we confirm ARC requirements and manage any required notification or submission before permit filing. Generator pad placement is designed to satisfy ARC setback and screening requirements before we proceed to permit submission — so HOA approval and permit approval run concurrently rather than sequentially.
Permit Application — Correct Office for Your Gaithersburg Community
We prepare and file all electrical permits at the correct office — City of Gaithersburg DPW for Kentlands and Lakelands; MoCo DPS at 2425 Reedie Drive for Crown Farm, Washingtonian Woods, and unincorporated areas. Complete submission packages prepared in-house. We manage all correspondence and track permit approval. You do not contact either permit office at any point in the process.
Electrical Work & Inspection — Full Coordination In-House
Our licensed electricians complete all work and we schedule all required inspections with the applicable permit office. For Kentlands and Lakelands, inspections are coordinated with City of Gaithersburg inspectors. For Crown Farm and unincorporated areas, MoCo DPS inspectors. We are present at all inspections and address any inspector comments before the project closes. Final testing with you and written warranty documentation at project close.
What Gaithersburg Homeowners Say About DMV General Contracting Group
"We installed two EV chargers in our Kentlands garage — one for each car. DMV General Contracting Group assessed our 200A panel, confirmed it could support both chargers without an upgrade, pulled the permit with the City of Gaithersburg DPW (not MoCo DPS — our previous quote was from a contractor who didn't know the difference), and installed both Tesla Wall Connectors in one day. Both cars charge overnight without any load issues."
"We wanted a whole-home Generac generator in Kentlands. DMV General Contracting Group confirmed the Kentlands ARC requirements for generator placement first — pad location, setbacks from property lines, and screening — designed the installation to meet those standards, then filed the City of Gaithersburg permit. The ARC confirmation and permit submission happened concurrently. The generator was installed and ARC-compliant from day one."
"Our Crown Farm home needed a 400A service upgrade — two EVs, a heat pump, and the house was pushing 200A capacity constantly. DMV General Contracting Group upgraded us to 400A, added a dedicated circuit for each EV charger, and handled all the MoCo DPS permits. They knew immediately that Crown Farm files with MoCo DPS, not the City. The 400A upgrade was the right scope — we haven't had a single load conflict since."
"We bought an older Gaithersburg home off Quince Orchard Road and discovered a Federal Pacific panel at inspection. DMV General Contracting Group replaced it with a 200A upgrade, added GFCI protection in the kitchen and bathrooms, and installed an EV charger circuit in the garage — all under one MoCo DPS permit. They confirmed our property was MoCo jurisdiction, not City, and filed accordingly. Inspection passed first time."
⭐ 4.9-star rated with 97+ verified homeowner reviews. Gaithersburg homeowners trust DMV General Contracting Group for electrical work that confirms the correct permit jurisdiction before any work begins — City of Gaithersburg DPW for Kentlands and Lakelands, MoCo DPS for Crown Farm and unincorporated areas — manages HOA ARC requirements for Kentlands generator installations, and serves both Gaithersburg's newer planned communities and its older housing stock with equal expertise.
