Can you put an outlet on a kitchen island in DC? (2014 NEC)

Short answer. Yes. In DC, a receptacle on a kitchen island or peninsula is not only permitted — it is required, and it may be mounted on the side of the cabinet. DC's adopted electrical code is the 2014 NEC (the DC Electrical Code, DCMR Title 12-E, 2017 supplement cycle). The "you can't put an outlet on the island panel anymore" rule that installers have heard about is a 2020/2023 NEC change that DC has not adopted.

What the 2014 NEC requires

• 210.52(C)(2) — at least one receptacle is required at each island counter space with a long dimension of 24 inches or more. A peninsula counter is treated the same way under 210.52(C)(3).
• 210.52(C)(5) Exception — that receptacle may be mounted on the side of the cabinet, up to 12 inches below the countertop, provided the countertop overhang does not exceed 6 inches beyond its support base. Side-panel mounting is expressly allowed.

So for a project permitted under DC's current code, the island or peninsula side-panel outlet is compliant and expected. The two things to verify on any install are that the overhang is 6 inches or less and the receptacle sits no more than 12 inches below the counter.

Where the "ban" actually comes from

The confusion traces to two later NEC cycles that DC has not adopted:

• 2020 NEC added 406.5(E) (receptacles may not be installed face-up in a countertop or work surface) and revised 210.52(C) to eliminate the below-counter side-face mounting allowance, steering installers toward pop-up or listed in-island assemblies.
• 2023 NEC went further and removed the island/peninsula receptacle requirement altogether.

Both of these are newer than DC's adopted edition. Under the 2014 NEC that governs DC, neither change applies.

Practice note

The instinct that "that's a newer-code thing DC hasn't adopted yet" is correct. When DC eventually moves to a 2020-or-later NEC cycle, this rule flips — so on any project it is worth confirming the code edition in force at the time the permit is issued.
