What generally governs the number of electrical outlets required in a residential room?

The number of electrical outlets required in a residential room is primarily governed by local codes. These codes are established by governmental entities to ensure safety and standardization, taking into account various factors such as the size of the room, its intended use, and safety considerations such as overloading and accessibility.

Local codes typically specify the minimum number of outlets based on these criteria, which helps in preventing electrical hazards and ensuring that homeowners have enough outlets for their electrical needs. While homeowner preferences, manufacturer recommendations, and design guidelines may influence the actual layout or installation of electrical outlets, they do not carry the same binding authority as local building codes. Therefore, compliance with local codes is essential for both safety and regulatory purposes in residential construction.
