Most electrical work in Olney requires a permit and a final inspection. Here is when a permit is typically needed in Montgomery 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 Montgomery 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.
About Our Olney Services
Olney is a Census-designated community in northern Montgomery County, sitting at the historical edge of the Washington metropolitan area where the suburban density of the inner Beltway transitions to larger-lot single-family development and remaining agricultural land. The community grew rapidly during the 1970s-90s as Montgomery County's residential development pushed north along Georgia Avenue (MD-97), and most of Olney's roughly 34,000 residents live in single-family homes on substantial lots in neighborhoods like Cherrywood, Olney Mill, Hallowell, Cashell Estates, and Brooke Manor.
The Olney housing mix presents a particular electrical-work profile. The bulk of single-family homes were built between 1975 and 1995, with 100-amp service standard for the era. Those panels are now at end-of-life, and we do steady panel-upgrade work to 200-amp service throughout Olney, typically tied to EV-charger installations, generator hookups and battery backup, or kitchen and master-bath renovations. Older homes from the 1960s and earlier in the historic Olney village area present additional challenges — some still have 60-amp fuse boxes, ungrounded sections, and limited circuit capacity that require more substantial rewires.
Olney's larger-lot properties can require careful planning for well and septic loads, detached buildings, landscape lighting, pools, outdoor kitchens, EV charging, and backup power. Backup options may include listed transfer or interlock equipment and an inlet for an owner-supplied portable generator, or compatible listed battery integration. The written design identifies supported loads, usable capacity, placement, transfer behavior, recharge path, and responsibility boundaries; AJ Long Electric does not sell the portable generator.
The Olney village center along Georgia Avenue has a small commercial corridor with restaurants, retail, and professional offices. We handle tenant electrical and small-commercial work in this area alongside our residential focus.
Olney homeowners choose AJ Long Electric for our experience with larger-lot residential electrical, transparent flat-rate pricing, and our workmanship warranty backing every job.
