How many receptacles are required on a balcony, deck, or porch with a usable area of less than 20 square feet?

For a balcony, deck, or porch with a usable area of less than 20 square feet, the National Electrical Code (NEC) specifies that at least one receptacle must be installed. This requirement ensures that there is a convenient power source available for temporary equipment such as lighting, electric grills, or other outdoor appliances that may be used in such areas, promoting safety and functionality.

The reasoning behind this requirement is based on the practical use of outdoor spaces. Even a small balcony or deck can benefit from having at least one electrical receptacle, allowing for flexibility when using electrical devices.

In larger spaces, additional receptacles might be mandated to accommodate varying activities. However, for areas under 20 square feet, the single receptacle is considered sufficient to meet basic needs while adhering to code regulations.
