All-Electric Building — No Gas Piping, Meters or Appliances Sign belongs in a building-owner catalog because small physical compliance items are often discovered only when an inspector, tenant complaint or violation points out that something is missing, damaged or posted incorrectly. An all-electric/no-gas sign can help clarify building conditions, but it is not part of the core HPD all-buildings signage list shown on HPD’s required-signage page. Use only where an agency, utility, plan or building procedure calls for it. For an owner, having a clear source for the right sign, frame or posting hardware reduces the time between identifying the deficiency and correcting the physical condition. It also helps standardize replacement items across a portfolio. This does not mean the item is legally required in every building: requirements depend on city, state, occupancy, number of units, building systems and the language of the actual violation. Before ordering, compare the product’s wording, dimensions, language, material and mounting method with the official rule or agency sample. Buying the object is only one part of compliance; correct installation, placement, documentation and any required certification or filing still matter.
