4.1.2 FACTORY BUILT HOUSING

Factory built housing may be placed on a lot zoned for residential use, in accordance with applicable zoning and form district requirements and provided that the standards of this section are met.

  1. NOTE: Factory built housing includes manufactured homes and modular homes as defined in the 2002 Kentucky Residential Code.
    The following standards are applicable to all factory built housing:
    1. The structure shall be permanently attached to a permanent foundation system and shall be anchored in accordance with the state standards set forth in KRS 227.570 through KRS 227.590.
    2. Exterior material shall be material customarily used on site-built dwellings, such as board siding, plywood or press wood siding, non-glossy vinyl siding, stucco, brick or non-reflective aluminum.
    3. Roofing material shall be of wood, tile or composition shingles, and must have an eave projection of no less than 6 inches
    4. Exterior covering material extending from the roofline to the ground or to the top of the foundation shall be used. Masonry type skirting shall be constructed from the ground to the bottom of the exterior wall.
    5. Structural additions or alterations shall be subject to the same building code regulations as apply to additions or alterations to a conventionally built house. Any other alteration or conversion of a factory built house must be performed in accordance with KRS 227.550 et seq., 815 KAR 25:050, Section 2 and 42 USC Chapter 70.
    6. An adequate guttering and roof drainage system shall be installed.
  2. The following standards are applicable to all factory built housing to be placed on lots that qualify as infill sites in the form district regulation applicable to the site:

    NOTE: Infill development is defined in the Neighborhood and Traditional Neighborhood Form Districts: Infill in NFD: Where 50% of more of either the lots or street frontage (lineal distance) within 200 feet of the subject site and on the same side of the street are occupied by principal structures. Infill in TNFD: Where 50% or more of either the lots or street frontage (linear distance) within the same block face are occupied by principal structures,
    1. 1 For example, an infill structure with four inch vinyl lapped siding may locate next to a home with wood lapped siding of similar dimension.
      Roofed front porches must be included on each structure if more than 50% of the structures in the same block face or within 200 feet of the subject site, whichever is less, include them. Porches shall , equal the average size and must resemble the architectural style, roof pitch, foundation and façade material of porches existing within the block face. The Planning Director shall determine if the proposed porch design is sufficiently similar to those of adjacent residences.
    2. Façade materials shall match in appearance1 those of one of the adjacent residences (residential buildings on either side of the infill lot, or two nearest residences, if the adjacent structures are non-residential). The Planning Director may approve alternative materials, if the Director finds that the proposed design and façade materials are substantially in keeping with the existing character of the block face.
    3. Front facing windows must have consistent size, spacing, and proportion to that of the adjacent residences (residential buildings on either side of the infill lot, or two nearest residences, if the adjacent structures are non-residential). The Planning Director may approve alternative window sizes and patterns, that the Director determines are in keeping with the existing character of the block face.
    4. The first floor elevation of the proposed dwelling shall be no lower than the average floor elevations of the existing adjacent residential buildings (residential buildings on either side of the infill lot, or two nearest residences, if the adjacent structures are non-residential).
    5. Minimum width of each unit’s first story shall be at least equal to the average of the two nearest residential buildings in the same block face (residential buildings on either side of the infill lot, or two nearest residences, if the adjacent structures are non-residential).
    6. The roof of each infill unit shall have pitch at least as steep as the average of the roof pitch of the two nearest residential buildings in the same block face. The Planning Director may approve a lower roof pitch if the Director finds that the adjacent roof pitches are not representative of the block face in which the factory built home is to be located.
    7. Infill structures shall be consistent in number of stories with the pattern established by surrounding residences; if more than 50% of existing residences within the block face (TNFD) or 200 feet distance (NFD) are more than one story in height, the infill structure shall be a two-story structure. Where the established pattern is story and a half (e.g., “camelback structures”), infill housing may have a full or partial second story.
    8. HVAC units shall not be located between the front façade and the street.
    9. In Landmarks Districts, design review and approval by the Landmarks Commission shall substitute for the requirements established in paragraphs B.1 through 8, above.
    10. The Planning Director may approve proposed developments of five or more infill units that vary from the standards listed in this 4.1.3.B, if the Director finds that the units are compatible with the neighborhood in which they will be located.
  3. The following standards are applicable to all factory built housing to be placed on lots that do not qualify as infill sites in the form district regulation applicable to the site:
    1. The roof shall be pitched at a minimum slope of 5:12.
    2. The minimum width of each structure’s first floor shall be at least 20 feet. In the TNFD, 14 wide units are permissible, if the unit has a second story (full or partial) and has a main entrance facing the street.
    3. HVAC units shall not be located between the front façade and the street.
    4. Each residence must measure at least 900 square feet of floor area not including basement or garage space.
  4. The Planning Commission may approve factory built housing that does not conform to one or more of the standards listed in sub-sections 4.1.2.B or C, above, if the Commission finds that the proposed housing:

4.1.3 LIGHTING

  1. Purpose and Intent

    The purpose of this section is to appropriately regulate outdoor lighting in Louisville and Jefferson County to reduce the effects of light trespass and glare, provide clear guidelines for the installation of outdoor lighting to maintain and compliment the community’s character, and to provide a safe nighttime environment for pedestrians, motorists, and properties. This regulation will implement the following Cornerstone 2020 Community Form Strategy Goals and Objectives: A3.1, A3.4, B2.6, C2.5, C4.6, D4.3, E2.4, E4.3, F4.4, G2.4, G4.3, H2.5, and H4.3.

    It is the intent of this regulation to provide for the health, safety and welfare of the residents of Jefferson County by regulating the placement, hours of operation, orientation, distribution patterns, intensity, and fixture types of all outdoor lighting used for the illumination outside the public right-of-way while encouraging lighting that conserves energy, reduces light pollution, and enhances nighttime enjoyment of the property within the County, without decreasing safety, utility, security, and productivity.

    The following definitions are not a Part of this Chapter, but are included to allow for the review of this Part without referring to other portions of this Land Development Code.

    Direct Light = light emitted directly from the lamp, off of the reflector or reflector diffuser, or through the refractor or diffuser lens, of a luminaire.

    Fixture = the assembly that houses the lamp or lamps and can include all or some of the following parts: a housing, a mounting bracket or pole socket, a lamp holder, a ballast, a reflector or mirror, and/or a refractor or lens.

    Flood Light = a form of lighting fixture designed to direct the output of a contained lamp in a more-or-less specific direction, utilizing reflecting or refracting elements located external to the lamp.

    Footcandle = the unit of illuminance on a surface one square foot in area on which there is a uniformly distributed flux of one lumen, or the illuminance produced on a surface all points of which are at a distance of one foot from a directionally uniform point source of one candela.

    Fully-Shielded Light Fixture (also known as Full-cutoff) = a lighting fixture constructed in such a manner that all light emitted by the fixture, either directly from the lamp or a diffusing element, or indirectly by reflection or refraction from any Part of the luminaire, is projected below the horizontal and meets IESNA criteria for fully-shielded (or full-cutoff) fixtures. Any structural Part of the light fixture controlling light emissions must be permanently affixed.

    Glare = light emitting from a luminaire with an intensity great enough to reduce a viewer's ability to see, and in extreme cases causing momentary blindness.

    Height of Luminaire = the height of a luminaire shall be the vertical distance from the ground directly below the centerline of the luminaire to the lowest direct-light-emitting part of the luminaire.

    Indirect Light = direct light that has been reflected or has scattered off of other surfaces.

    Lamp = the component of a luminaire that produces the actual light.

    Landscaping Lighting = type of outdoor lighting used to illuminate landscaping areas (flower beds, trees, vegetation) and other aesthetic features on a parcel (flag poles, etc.).

    Light Trespass = the shining of light produced by a luminaire beyond the boundaries of the property on which it is located.

    Lumen = a unit of luminous flux. One footcandle is one lumen per square foot. For the purposes of this Regulation, the lumen-output values shall be the INITIAL lumen output ratings of a lamp.

    Luminaire = a complete lighting system, and includes a lamp or lamps and a fixture (See Appendix 4A for examples of acceptable luminaires).

    Outdoor Lighting = the night-time illumination of an outside area or object by any man-made device located outdoors that produces light by any means. This includes luminaires used to illuminate advertising signs, landscaping, architectural features, walkways, driveways and parking areas.

    Sag-lens or Drop-lens = a clear or prismatic refracting lens that extends below the lowest opaque portion of a light fixture.

    Shielded (also known as cutoff) Light Fixture = a lighting fixture constructed in such a manner that no more than 2.5 percent of the lamp lumens, either directly from the lamp or a diffusing element, or indirectly by reflection or refraction from any Part of the luminaire, are not emitted above the horizontal plane through the lowest direct-light-emitting Part of the luminaire.

    Spotlight = a lighting assembly designed to direct the output of a contained lamp in a specific tightly focused direction (a beam) with a reflector located external to the lamp.

    Temporary Outdoor Lighting = the specific illumination of an outside area or object by any man-made device located outdoors that produces light by any means for a period of less than 15 days, with at least 180 days passing before being used again.

    Uniformity Ratio = the relationship between the average level of illumination and the lowest level of illumination for a given area. For example, if the uniformity ratio is 3:1 and the average illumination of an area is 3.0 footcandles, then the lowest level of illumination allowed in the given area would be 1.0 footcandles.
