As an AI language model, I don't have access to a specific country or region's building code, but in general, the National Electrical Code (NEC) provides guidelines for the number of electrical outlets required in various rooms. Some key points to consider while calculating the number of outlets required per room according to the building code are:
1. The minimum number of receptacles required in a room is based on the square footage of the room, with a minimum of one receptacle per wall in the room. The NEC mandates a general requirement for a minimum of one 120V branch circuit per room, and this branch circuit must provide electrical energy to all outlets exclusively in that room.
2. Special-purpose rooms like kitchens, laundry rooms, garages or workshops may require additional outlets. Kitchen countertops, for instance, need a minimum of two 20-amp small appliance circuits that can only supply the countertop and don't power other appliances. Similarly, laundry rooms must have at least one receptacle for the washing machine, one receptacle for the dryer, and one GFCI-protected receptacle within six feet of the sink.
3. Code-required circuits must be wired with tamper-resistant receptacles (TRRs) in residential areas.
4. The National Electrical Manufacturers Association (NEMA) provides guidance on outlet spacing (e.g. receptacles must be spaced so that no point on the wall space exceeds six feet to reach an outlet) which must also be considered.
To determine the precise number of outlets mandated by building codes, refer to your local codes and hire an electrician to make repairs or install new wiring to ensure compliance.
