Determining if a specific area in a home is actually considered an alcove or a foyer can be easy if there happens to be a set of plans that names each area.

In the OESC, an Alcove is defined as an area extending from, and returning to, the common wall of hallways, foyers, entries, and landings with a depth of not less than 600 mm (2 ft) and a length of not less than 900 mm (3 ft).

In Oregon, Section 210.52(J) was added with the following language to address alcoves:

210.52(J) Alcoves. In dwelling units, alcoves shall have at least one receptacle installed. These outlets shall be in addition to the required hallway outlets.

Oregon amendments to the 2023 NEC® are located in “Table 1-E” of the Oregon Electrical Specialty Code (OESC) which can be seen using the following link or the OESC PDF file located near the bottom of the screen: 2023 OESC
