§ 23.04.040. Construction and maintenance regulations  


Latest version.
  • The following regulations shall apply to all construction and maintenance of awnings, permanent awnings, venetian awnings, suspended canopies, supported canopies and marquees:

    AWNINGS GENERALLY. Awnings over public areas in the city shall be arranged without posts and shall provide a clearance of not less than seven feet from sidewalk to the lowest point of the framework, and no part of such awning cover, including any fringe, apron, skirt, valance or drop, shall be less than six feet, six inches above the surface of the sidewalk immediately below when the awning is lowered for use, except the bottom of awning covers enclosing the ends of awnings shall be six feet, eight inches above the surface of the sidewalk. No awning less than thirteen feet above the street, alley or sidewalk shall be closer to the vertical plane of the curb than two feet and in no case shall any awning project from the face of the building more than eight feet. All awnings shall be covered with substantial material.

    All fixtures such as lateral arms, center supports, gears and pin ends shall be fastened to steel backing where available, by drilling and bolting through from the back when possible, or drilling, tapping and fastening with not less than three-eighths inch machine bolts. Where wood backing only is available, bolt through from the back wherever possible, using large washers under heads of bolts; otherwise use lag screws from the front at least four inches long. When anchorage is to be made in brick, stone or terra cotta, approved expansion bolts shall be used. Lock washers shall be used on all bolts.

    Every awning shall be rolled or folded against the building except when serving as a protection from sun, rain, snow or other inclement weather.

    FABRIC-COVERED AWNING CONSTRUCTION. Pipe rollers shall be no less than one and one-half inches inside diameter galvanized steel pipe, or one and one-half inches outside diameter seamless steel tubing. On pipe rollers over twenty feet in length where it becomes necessary to join two or more sections together, splicing must be effected by using cast steel gudgeons, roller ends to be properly riveted to the same. This also applies to pin end gudgeons. Metal rollers shall be drilled or perforated with holes of a size to make a driving fit with roofing nails (about one-eighth inch). These soles shall be spaced not over three inches center to center for the first three holes on each end, spacing between to be approximately six inches center to center. Fabric covering shall be attached to a metal roller by means of large-headed roofing nails fitted solidly into these holes.

    When using steel rollers, no center supports shall be necessary on awnings under twenty feet. Over twenty feet, center supports shall be spaced as follows:

    Awning lengths Number of
    supports necessary
    20 to 30 ft. 1
    30 to 40 ft. 2
    40 to 60 ft. 3

     

    One additional center support for each additional fifteen feet or fraction thereof.

    On awnings having an extension of four feet or more from the point of fastening on the building, three-fourths inch inside diameter galvanized pipe extension arms shall be used. No extension bars shall be used less than five-eighths inch in diameter and shall be galvanized.

    Two arms shall be used for awnings not over twenty feet in length. On awnings over twenty feet, a center arm must be provided for each additional eight feet or fraction thereof added to the length of the awning.

    Awnings suspended on lateral arms shall require the number of arms as per the following schedule:

    Awning lengths Number of arms
    required
     0 to 22 ft. 2
    22 to 30 ft. 3
    30 to 40 ft. 4

     

    One additional arm for each ten feet or fraction thereof thereafter.

    Wherever possible an even number of lateral arms shall be used.

    Front bars shall be galvanized one inch inside diameter or grade "A" clear fir or comparable timber dressed to size 2 inches × 3 inches and corners properly leveled.

    Roller awnings shall be operated by self-locking, steelcut, wormtype gear fixtures.

    Roller sprocket wheels and link chains shall not be permitted.

    The design, construction and erection details of all awnings, other than those herein specifically provided for, shall be submitted to the building inspection superintendent for approval before erection work is started.

    VENETIAN AWNINGS. No awning, shutter or louver of metal, wood or other rigid material shall be erected or maintained in such a way that it will impede the entrance into the building of members of the fire department, or in such a manner that it will bar the way of persons seeking to escape from fire or panic in a building, and no shutter or louver of this type shall be placed in any opening giving access to a fire escape or other intended means of escape. No fixed frame shall be placed on any window or door opening in an assembly hall or public hallway in an apartment or hotel building, but nothing shall prohibit the erection of such an awning on these openings provided they can be opened as provided in the following paragraph:

    Any awning, shutter or louver of metal, wood or other rigid material attached to the windows of a building above the first story shall be arranged in such a manner that it may be easily opened so as to afford easy ingress and egress, and such awning, shutter or louver shall be constructed so that it may be easily opened from both the inside and outside without any special tool and without special knowledge or skill. No awning, shutter or louver of metal, wood or other rigid material weighing over one pound per square foot shall be attached to the wood jambs, frames or other wood members of a building (frame buildings excepted) when such building is within ten feet of public property. All venetian awnings erected above the first story shall be equipped with at least one safety chain securely fastened to the awning and frame.

    SUSPENDED CANOPIES shall be supported throughout by metal framework. They may extend over public sidewalks or parking portions of a public street to a distance of not to exceed seven feet; provided, that a suspended canopy not over ten feet in width measured parallel to the building may extend a distance not to exceed twelve feet. In no case, however, shall the outer edge of the canopy extend closer to the vertical plane of the curb than two feet nor shall it come within two feet of the property line (extended toward the curb). All such suspended canopies shall be securely and rigidly supported and maintained so that no part of the framework of such suspended canopy shall be less than eight feet above the surface of the sidewalk immediately below and no part of such canopy covering, including any fringe, apron, skirt, valance or drop shall be less than seven feet above the surface of the sidewalk immediately below.

    A SUPPORTED CANOPY may be erected for a period not to exceed seven days when approved by the building inspection superintendent: provided, that the fee is paid and the permit is secured: provided further, however, that a supported canopy may be erected for a period of not to exceed twenty-four hours and no permit or fee will be required. All supported canopies shall be adequately supported and braced and shall be safely maintained and well lighted at night, and the abutting property owners shall save the city harmless from all claims of every kind or nature arising out of the erection, use and dismantling of such canopy over public property.

    MARQUEES, extending over public property, shall have their main framework and support of noncombustible material and shall be designed by a structural engineer and approved by the building inspection superintendent. They shall have a clearance of at least ten feet above public property, shall not extend closer to the vertical plane of the face of the curb than two feet, nor shall they come within two feet of the adjoining side property line, extended toward the curb. Marquees extending not further than two feet from the front building line may have a clearance above public property of not less than eight feet and, except in fire zone No. 1 as set forth in the building code as set out in Title 18 of this code, may be built of combustible materials. Such marquees may also extend to the side property line. The roofs of all marquees shall be so drained as not to discharge water upon the public sidewalk.

    PERMANENT AWNINGS, extending over public property shall be of rigid construction, of either combustible or noncombustible material, so designed that the roof portion shall be partly open to insure release of air pressure built up under the awning. All parts of the roof shall have a slope of not less than fifteen degrees with the horizontal. The structure shall be well braced and securely fastened with bolts or lagscrews to the building to which it is attached. The method of construction and attachment shall be approved by the building inspection superintendent. No part of any permanent awning shall be closer to the public walkway below than seven feet nor shall it extend more than seven feet from the face of the building to which it is attached. No awning of this description within thirteen feet of the walkway shall be closer than two feet from the vertical plane of the curb.
