Section 202 — DEFINITIONS

202 Add this definition [1] as follows:

ALL-ELECTRIC BUILDING OR PROJECT. A building or project that uses a permanent supply of electricity as the source of energy for all on-site space conditioning (including heating and cooling), water heating (including pools and spas), cooking appliances, and clothes drying appliances. Use of steam generated off-site for space conditioning, water heating, laundry equipment, or cooking appliances is permitted. An All-Electric Building or Project may not install natural gas or propane piping systems, fixtures, or infrastructure for those purposes in or in connection with the building, structure, or within property lines of the premises, extending from the point of delivery at the gas meter. An All-Electric Building or Project may contain natural gas infrastructure dedicated solely to serve appliances covered by the Federal Energy Policy and Conservation Act (42 U.S.C. §§ 6201 et seq. ), provided that the building complies with Design Guidelines and Review Procedures for Public Safety and Electric-Ready Construction published by the Department of Building Inspection. All-Electric Projects include additions or expansions of existing buildings that constitute Substantial Improvements as defined by Section 202 of this code, where the unaltered building area may remain a Mixed-Fuel Building.

ELECTRIC-READY. A building, project, or portion thereof that contains electrical systems and designs that provide capacity for a future retrofit of a Mixed-Fuel Building to an All-Electric Building. Electric-Ready includes sufficient space, drainage, electrical conductors or raceways, bus bar capacity, and overcurrent protective devices to provide capacity for a future retrofit to an All-Electric Building as specified in the Design Guidelines for Electric-Ready Buildings published by the Department of Building Inspection.

KITCHEN, RESIDENTIAL. That portion in a residential dwelling unit that is a room or area used for cooking, food storage and preparation and washing dishes, including associated counter tops and cabinets, refrigerator, stove, ovens and floor area.

MAJOR RENOVATION. An alteration or addition to an existing building that includes Substantial Upgrade to Mechanical Systems, and one or more of the following:

(1) a Non-structural Alteration that is substantial pursuant to Section 503.11.1 or Section 304.5 of the San Francisco Existing Building Code;

(2) a Substantial Structural Alteration as defined by Section 202 of the San Francisco Existing Building Code;

(3) an addition that is a Substantial Improvement as defined by Section 202 of this Code.

MAJOR SYSTEM. A space heating or water heating system serving 80% or more of total conditioned floor area of the building.

MIXED-FUEL BUILDING. A building that uses natural gas or propane as fuel for space heating or cooling, exterior heating, decorative uses and lighting, water heating (including pools and spas), cooking appliances or clothes drying appliances, onsite generation of electricity (except where primarily fueled by onsite digestion of organic material), or contains fixtures, piping systems, or infrastructure for natural gas or propane equipment for such uses.

SUBSTANTIAL UPGRADE TO MECHANICAL SYSTEMS. An alteration or addition to an existing building where the proposed project either:

(1) Replaces space heating and hot water heating system for the entire building; or

(2) Installs space heating and water heating systems that will serve 80% or more of the total conditioned floor area of the building; or

(3) Installs space conditioning or water heating systems serving the area of addition.
