Prior history: Prior code Sections C12-785, C12-787 through C12-790, C12-793, C12-794 and C12-795; Ord. No. 174.

The purpose of this Chapter is to provide minimum standards to safeguard property and public welfare by regulating and controlling the design, construction, quality of materials, and use and occupancy, location and maintenance of all buildings and structures within the city relating to building security. (Ord. 227 § 1 (part), 1992)

A. The provisions of this chapter shall apply to new construction and to buildings or structures, except occupancy group R-3, to which additions or alterations are made except as specifically provided by this chapter. When additions or alterations are made, except those made to buildings and structures in occupancy group R-3, within any twelve-month period which exceed fifty percent of the value of the existing buildings or structures, such buildings or structures shall be made to conform to the security requirements for new buildings and structures. B. Existing multiple-family dwelling units which are converted to privately owned family units (condominiums) shall comply with the special residential building provisions set out in Section C2-8 of this chapter. C. Any existing structure which converts from its original occupancy group as designated in this code, shall comply with the provisions of this chapter. D. Any building, as defined in this code and in Title 19 of the California Administrative Code, requiring special type releasing, latching or locking devices, other than described in this chapter, shall be exempt from the provisions hereof relating to locking devices of interior and/or exterior doors. (Ord. 227 § 1 (part), 1992)

For the purpose of this chapter certain terms are defined as follows: Auxiliary locking device means a secondary locking system added to the primary locking system to provide additional security. Bolt is a metal bar which, when actuated, is projected (or thrown) either horizontally or vertically into a retaining member, such as a strike plate, to prevent a door or window from moving or opening. Bolt projection or bolt throw is the distance from the edge of the door, at the bolt centerline, to the farthest point on the bolt in the projected position. Burglary resistant glazing means those materials as defined in U.L. Bulletin 972. Commercial building means a building, or portion thereof, used for a purpose other than a dwelling. Component, as distinguished from a part, is a subassembly which combines with other components to make up a total door or window assembly. For example, the primary components of a door assembly include: door, lock, hinges, jamb/wall, jamb/strike and wall.

City of San Ramon, CA | Municipal Code 370

Cylinder means the subassembly of a lock containing the cylinder core, tumbler mechanism and the keyway. A double cylinder lock is one which has a key-actuated cylinder on both the exterior and interior of the door. Cylinder core or cylinder plug is the central part of a cylinder containing the keyway, which is rotated by the key to operate the lock mechanism. Cylinder guard means a tapered or flush metal ring or plate surrounding the otherwise exposed portion of a cylinder lock to resist cutting, drilling, prying, pulling or wrenching with common tools. Deadbolt is a lock bolt which does not have a spring action, as opposed to a latch bolt, which does. The bolt must be actuated by a key or a key and a knob or thumb turn and when projected becomes locked against return by end pressure. Dead latch or deadlocking latch bolt means a spring actuated latch bolt having a beveled end and incorporating a plunger which, when depressed, automatically locks the projected latch bolt against return by end pressure. Door assembly is a unit composed of a group of parts or components which make up a closure for an opening to control passageway through a wall. For the purposes of this chapter a door assembly consists of the following parts: door; hinges; locking device or devices; operation contacts (such as handles, knobs, push plates), miscellaneous hardware and closures; the frame, including the head, threshold and jambs, plus the anchor frame, including the head, threshold and jambs, plus the anchorage devices to the surrounding wall and a portion of the surrounding wall extending thirty-six inches from each side of the jambs and sixteen inches above the head. Door stop means that projection along the top and sides of a door jamb which checks the door's swinging action. Double-cylinder deadbolt means a deadbolt lock which can be actuated only by a key on both the interior and the exterior. Dwelling means a building, or portion thereof, designed exclusively for residential occupancy, including single-family and multiple-family dwellings. Flushbolt is a manual, key or turn-operated metal bolt normally used on inactive doors and is attached to the top and bottom of the door and engages in the head and threshold of the frame. Fully tempered glass means those materials meeting or exceeding ANSI standard Z97.1 - Safety Glazing. Jamb means the vertical members of a door frame to which the door is secured. Jamb/wall is that component of a door assembly to which a door is attached and secured; the wall and jamb used together are considered a unit. Key-in-knob means a lockset having the key cylinder and other lock mechanisms contained in the knob. Latch or latch bolt is a beveled, spring-actuated bolt which may or may not have a deadlocking device. Lock (or lockset) is a keyed device (complete with cylinder, latch or deadbolt mechanism and trim, such as knobs, levers, thumb turns, escutcheons and the like) for securing a door in a closed position against forced entry. For the purpose of this chapter, a lock does not include the strike plate. Locking device is a part of a window assembly which is intended to prevent the movement of the movable sash, which may be the sash lock or sash operator. Occupancy group is that which is identified as group in Table 5-A of the 1991 Uniform Building Code and may be referred to as ("description - occupancy" e.g., "R-1 occupancy"). City of San Ramon, CA | Municipal Code 371

Multiple-family dwelling means a building, or portion thereof, designed for occupancy by two or more families living independently of each other, including hotels, motels, apartments and townhomes. Panic hardware means a latching device on a door assembly for use when emergency egress is required due to fire or other threat to life safety. Such devices are designed so that they will facilitate the safe egress of people in case of an emergency when a pressure not to exceed fifteen pounds is applied to the releasing device in the direction of exit travel. Such releasing devices are bars or panels extending not less than two-thirds of the width of the door and placed at heights suitable for the service required, not less than thirty inches and not more than forty-four inches above the floor. Part, as distinguished from component, is a unit (or subassembly) which combines with other units to make up a component. Primary locking device means the single locking system on a door or window unit whose primary function is to prevent unauthorized intrusion. Private or single-family dwelling means a building designed exclusively for occupancy by one family. Rail means the horizontal member of a window or door. A meeting rail is one which mates with a rail or another sash or a framing member of the door or window frame when the sash is in the closed position. Sash is an assembly of stiles, rails and, sometimes, mullions assembled into a single frame which supports the glazing material. A fixed sash is one which is not intended to be opened. A movable sash is intended to be opened. Sill is the lowest horizontal member of a window frame. Single-cylinder deadbolt means a deadbolt lock which is activated from the outside by a key and from the inside by a knob, thumbturn, lever or similar mechanism. Solid-core door means a door composed of solid wood or composed of compressed wood equal in strength to solid wood construction. Stile is a vertical framing member of a window or door. Strike is a metal plate attached to or mortised into a door or door jamb to receive and to hold a projected latch bolt and/or deadbolt in order to secure the door to the jamb. Swinging door means a door hinged at the stile or at the head and threshold. U.L. listed means tested and listed by Underwriters Laboratory, Inc. Window assembly is a unit which includes a window and the anchorage between the window and the wall. Window frame is that part of a window which surrounds and supports the sashes and is attached to the surrounding wall. The members include side jambs (vertical), the head jamb (upper, horizontal), the sill and mullions. (Ord. 227 § 1 (part), 1992)
