Confirm the actual property jurisdiction and scope before deciding which permits or inspections apply. New circuits and service changes differ from like-for-like replacements. The authority determines the requirements for your project.
| Project | Planning Step | What It Means |
|---|---|---|
| Panel upgrade (e.g. 100A to 200A) | Confirm permit path | Replacing or upsizing the main electrical panel that distributes power throughout your home. |
| EV charger installation | Confirm permit path | Adding a dedicated 240V circuit for a Level 2 home electric-vehicle charger. |
| New circuits & rewiring | Confirm permit path | Identify the proposed circuit work and any changes to walls or protected assemblies. |
| Like-for-like fixture or device swap | Check exemptions | Confirm whether the exact replacement qualifies for an exemption; protected assemblies or other scope can change the requirement. |
Your written scope should identify permit and inspection coordination. For state trade licensing, see the Maryland Board of Master Electricians. Check master electrician licensing and Maryland electrical code requirements through the Department of Labor.
About Our Fort Washington Services
Fort Washington is a riverfront community in southern Prince George's County, named for the Fort Washington Park overlooking the Potomac directly across from Mount Vernon. The area mixes large estate-style waterfront properties along the river, established 1960s-80s subdivisions inland, and newer luxury developments around National Harbor and the MGM Resorts corridor.
Waterfront and near-waterfront housing presents specific electrical challenges that AJ Long Electric has years of experience with: flood-prone basement panels requiring careful elevation or relocation work, exterior receptacles needing weatherproof in-use covers and GFCI protection, dock and pier wiring with proper bonding and equipotential grounding, landscape lighting around large lots, and pool and hot-tub installations subject to NEC Article 680 (the strictest section of the National Electrical Code, covering all electrical work near water).
Inland Fort Washington neighborhoods — Tantallon, Forest Heights, Friendly, Oxon Hill — were built primarily between 1965 and 1985 and share the electrical profile of suburban Prince George's housing from that era: 100-amp panels at end-of-life, ungrounded sections, aluminum branch wiring in homes built during the 1970s window, and limited dedicated-circuit capacity for modern living. Most of our inland work in Fort Washington is panel upgrades, kitchen and bathroom rewires for renovations, EV charger installations, and backup-power work — battery power stations and portable generator hookups (transfer switches and inlet boxes).
The National Harbor and MGM corridor at the northern end of Fort Washington has brought hospitality, retail, and luxury-residential demand: tenant electrical fit-outs, restaurant kitchen circuits, landscape and sign lighting, and high-end residential work in the newer single-family and townhouse developments. We work both sides — established suburban homeowner work and new-construction commercial — with the same crews and the same quality standard.
Fort Washington homeowners along the Potomac choose AJ Long Electric for the same reason inland customers do: transparent pricing, code-compliant work, careful respect for property (especially relevant on waterfront lots with mature landscaping), and a workmanship warranty that means we come back if anything is not right.
