Most electrical work in Davidsonville requires a permit and a final inspection. Here is when a permit is typically needed in Anne Arundel County, and who governs electrical licensing in Maryland.
| Project | Permit Typically Required? | What It Means |
|---|---|---|
| Panel upgrade (e.g. 100A to 200A) | Yes | Replacing or upsizing the main electrical panel that distributes power throughout your home. |
| EV charger installation | Yes | Adding a dedicated 240V circuit for a Level 2 home electric-vehicle charger. |
| New circuits & rewiring | Yes | Running new wiring or replacing aging branch circuits, common in older Anne Arundel County homes. |
| Like-for-like fixture or device swap | Usually no | Replacing an existing light fixture, switch, or outlet with the same type in the same location. |
AJ Long Electric pulls every required permit and schedules inspections on your behalf. For official licensing and permit rules, see the Maryland Board of Master Electricians. Check master electrician licensing and Maryland electrical code requirements through the Department of Labor.
Davidsonville is a low-density, rural-residential community in central Anne Arundel County, Maryland, set between the South and Patuxent Rivers along the MD-214 (Central Avenue) corridor. Unlike the planned-subdivision density of nearby Crofton, Davidsonville is defined by large wooded lots, custom and estate-style homes, horse properties, and a deliberate agricultural-residential zoning character. That low-density profile shapes the electrical work here: longer service runs, more outbuildings and detached garages, well-and-septic infrastructure, and a real need for backup power.
Davidsonville's panel-upgrade work spans a wide age range, from 1960s-70s farmhouses and ranchers with original 100-amp service to 1990s-2010s custom homes whose larger footprints — multiple HVAC zones, detached garages or shops, pools, and now EV chargers — push a 200-amp service to its limits. AJ Long Electric upgrades these to 200-amp (or larger 320/400-amp metered) services where the load justifies it, runs dedicated feeders and sub-panels to detached garages, shops, and barns, and provides documented load calculations so owners of larger properties can see how the new circuits fit. Long underground service and feeder runs across deep, wooded lots are routine here, as are grounding-electrode-system corrections on older homes.
Because Davidsonville is rural and almost entirely on private well and septic systems, a power outage doesn't just mean lost lights — it means no water and no wastewater pumping. That makes backup power one of the most common pairings with a panel upgrade in this community: when the service is already open, we add a transfer switch or generator-inlet hookup so a portable or standby generator can carry well pumps, septic, heat, and critical circuits. AJ Long Electric installs the transfer switches, inlet boxes, and battery backup — we do not sell the generator itself. Davidsonville is served by Baltimore Gas and Electric (BGE), so every service upgrade includes coordinating the BGE meter pull and reconnection.
All of this is permitted through the Anne Arundel County Department of Inspections and Permits, which requires an electrical permit, inspection, and final approval for any service change, new feeder, or EV-charger install — and the county's rural zoning sometimes adds setback and outbuilding considerations to feeder runs. AJ Long Electric handles the permit, the inspections, and the BGE coordination, with clear flat-rate pricing for a 200-amp service upgrade, a detached-building feeder, an EV-charger circuit, or a whole-property backup-power hookup.
