A. Master Electrician Rex Cauldwell responds: Most old houses have too few receptacles to meet current code requirements. Any wall section 2 feet wide or wider requires a receptacle, and every point along any wall must be within 6 feet of a receptacle. Doors and fireplaces don't count as part of the wall, but fixed-glass panels (like the nonsliding half of a glass slider) do. So starting at a door frame or corner, you must place a receptacle within 6 feet, and one at least every 12 feet thereafter.

Receptacles dedicated to one specific appliance, floor receptacles more than 18 inches away from the wall, and receptacles more than 5 1/2 feet from the floor do not count as required receptacles.
