Buckingham is one of the most architecturally remarkable neighborhoods in Arlington County — a planned garden apartment complex built in the late 1930s and early 1940s that was, at its time, one of the largest and most thoughtfully designed residential developments in the Washington DC metro area. Its brick buildings, landscaped courtyards, and human-scale design have made it a historic preservation landmark. The electrical systems in its original buildings are approaching 90 years of continuous service, and preservation of the architecture does not change what nine decades does to the wiring inside the walls.
What 90-Year-Old Residential Wiring Looks Like in Practice
The original electrical systems in Buckingham’s 1938-era buildings were installed with the technology and standards of the New Deal era. Two-wire circuits without ground conductors, knob-and-tube wiring in the original construction, and fuse panels rated for loads that represent a fraction of what a contemporary apartment draws are the baseline electrical condition in units that have not been comprehensively renovated. The rubber insulation on conductors of that era has been degrading since before the Second World War. In buildings that have been occupied continuously — which Buckingham largely has been — the cumulative load cycling, thermal stress, and incidental physical disturbances of 90 years of residential use have not improved those conductors’ condition.
What Renovations Did and Did Not Fix in Buckingham’s Units
Many Buckingham units have been renovated by successive owners and the building management over the decades — new kitchens, bathroom updates, and in some cases comprehensive electrical upgrades that replaced the original wiring throughout the unit. Other units have received partial upgrades: a new kitchen circuit added to the existing system, a panel replacement that upgraded the fuse box but left the original branch circuit wiring in place, or cosmetic renovations that replaced fixtures and devices without addressing the conductors behind them. The result is a building where unit-to-unit electrical conditions vary enormously, and where a newly renovated unit can be adjacent to one whose wiring has not been professionally evaluated since the Eisenhower administration.
Electrical Conditions Most Often Found in Unrenovated Buckingham Units
- Original knob-and-tube branch circuit wiring with 80-plus years of insulation degradation
- Two-wire ungrounded circuits with no ground conductor throughout the unit
- Fuse panels or early 1950s breaker panels still in service
- No GFCI protection at bathroom or kitchen countertop locations
- Original circuit capacity inadequate for modern appliance loads
- No smoke detector hardwiring — battery-only units or no detectors at all
The Hardwired Smoke Detector Question in Buckingham
Virginia code requires hardwired, interconnected smoke alarms in residential dwelling units undergoing significant renovation. In unrenovated Buckingham units, battery-only smoke detectors that were placed on a shelf or mounted with a screw at some point in the past decade represent the only fire detection system in the unit. When those batteries die — which they do, typically at 3:00 AM during a cold snap when the alarm chirps until someone removes the battery — the unit may go days or weeks without functional fire detection while the occupant forgets to replace it. PRO Electric plus HVAC installs hardwired, interconnected combination smoke and CO detectors in Buckingham units — units that when one activates, all activate simultaneously — as a priority safety improvement that can be completed in a single visit regardless of the underlying wiring condition.
The GFCI Retrofit: The Fastest Safety Improvement in a Buckingham Unit
Adding GFCI protection to ungrounded circuits in Buckingham’s historic units is specifically permitted by the NEC — GFCI protection is one of the accepted alternative protection methods for circuits that lack a grounding conductor, provided the outlets are labeled “No Equipment Ground.” This is a straightforward device replacement at bathroom and kitchen locations that requires no new wiring, no wall openings, and no coordination with building management beyond written notification in most cases. PRO Electric plus HVAC performs this retrofit in Buckingham units as a one-to-two-hour scope that immediately addresses the most immediate safety gap without requiring a full rewiring project.

Historic Preservation and Electrical Upgrades: They Are Not in Conflict
Buckingham’s historic designation as a planned garden apartment community governs exterior modifications and character-defining architectural features. It does not prohibit electrical upgrades inside individual units. The visible interior finishes, the hardware, the window configurations — these are the historic fabric that preservation protects. The wiring inside the walls, the panel in the utility closet, and the detectors on the ceilings are safety infrastructure that can and should be updated without any conflict with preservation requirements. PRO Electric plus HVAC works in Buckingham units with full awareness of what the historic designation covers and what it does not — and performs the electrical work that makes these beautiful apartments safe to live in without touching the character that makes them worth preserving.
