13. Building Height.
    1. Maximum overall building height limits apply to the entire building.
    2. Minimum story (floor-to-floor) heights must be met along all street facing facades and for at least 75% of the story area.
    3. The following requirements apply to vertical mixed-use building types:
       1. The second story area must be covered and enclosed and equal at least 75% of the first story's floor area;
       2. The second story facade must extend the entire width of any first story building facade except for second story areas used for unenclosed or uncovered outdoor dining area, uncovered decks, uncovered balconies, unenclosed stairs and uncovered atriums; and
       3. The entire indoor area of the second story must be conditioned space (HVAC) and available for human occupancy.
14. Neighborhood Transition Height Limit.
    1. MID-MIX and MID-TRN-zoned lots that abut R-zoned lots or that are separated from R-zoned lots solely by alleys are subject to the neighborhood transition height limits of this subsection.
    2. Principal buildings may not exceed 3 stories or 35 feet in height within 30 feet of the lot line of the abutting or alley-separated R-zoned lot.
15. Transparency. Transparency regulations govern the minimum percentage of a street-facing building façade that must be covered by windows or glazed, transparent elements. In determining compliance with transparency requirements on a building facade, the transparency of each building story must be calculated separately.
16. Lot Edges.
    1. Description. The term "lot edge" refers to the area of a lot located immediately beyond the back of the sidewalk between:
       1. The back of the sidewalk and a principal building; and
       2. The back of the sidewalk and an allowed parking lot.
    2. Purpose. The design of lot edges helps define the transition between public and private property and contributes to the overall character of the area, particularly for pedestrians.
    3. General Lot Edge Regulations. Different lot edge types and elements are required in accordance with the regulations that apply to the different building types allowed in MID districts. The following general regulations apply to all lot edge types:
       1. Mechanical equipment and other building service may not be located in the lot edge along the front of the lot.
       2. Lot edges may not be used for vehicles, except for driveway or alley crossing, incidental service, maintenance or emergency actions.
       3. Landscape material used to satisfy lot edge tree planting and landscape requirements must comply with the standards of Sec. 24.12.050.
    4. Landscape Edge. Landscape edges are subject to the following regulations:
       1. Landscaping, such as trees, shrubs, groundcover plants, sod, or annual or perennial vegetation, must be provided in at least 70% of the lot edge area. The area of any stoops or porches is not counted in determining the total lot edge area.
       2. The landscape edge may not be used for vehicles, except for incidental service, maintenance or emergency actions.
       3. The landscape edge may not be covered, except by features allowed to encroach into required building setbacks (see Sec. 24.18.030-F).
       4. Landscape edges with a depth of 7 feet or more must be planted with at least one deciduous tree per 50 linear feet of street frontage, except where this condition is satisfied through preservation of existing on-site or adjacent street trees.
    5. Hardscape Edge. Hardscape edges are subject to the following regulations:
       1. Hardscape areas improved for pedestrian amenity or aesthetic appeal must be provided in at least 50% of the lot edge area. The area of any stoops or porches is not counted in determining the total lot edge area.
       2. Hardscape edges greater than 10 feet in depth must be planted with at least one deciduous tree per 50 linear feet of street frontage, except where this condition is satisfied through preservation of existing on-site or adjacent street trees.
       3. Hardscape edges must provide at least one bench or similar seating area per 50 linear feet.
       4. Hardscape edges may not be covered, except by features allowed to encroach into required building setbacks (see Sec. 24.18.030-F).
    6. Parking Edge.
       1. Lot edges that are immediately adjacent to an allowed parking lot are subject to following regulations:

          2. At least one point of pedestrian access in the form of paths, walkways, ramps, or stairs must be provided to connect the public sidewalk to the parking lot.
17. Edge Elements. Edge elements in the form of porches and stoops are required for detached house, two-unit houses, semi-detached house, attached house, and commercial house building types. When required, such elements are subject to compliance with the regulations of this subsection.
    1. Porches. Required porches must be located along the front facade and comply with the following:
       1. A porch must be at least 4 feet in depth, not including any steps leading to the porch.
       2. A porch must have a width of at least 20% of the building facade from which it projects.
       3. A porch must have a roof, but it may not be otherwise enclosed except by screens.
       4. Porches required under these MID district provisions may extend into a required front setback if such extension is at least 2 feet from all lot lines.
       5. A porch may not encroach onto the sidewalk or into the right-of-way.
    2. Stoops. Required stoops must be located along the front facade and comply with the following:
       1. A stoop may not exceed 6 feet in depth, not including any steps leading to the stoop.
       2. A stoop may have a cover but may not be enclosed.

       4. A stoop may not encroach onto the sidewalk or into the right-of-way.
18. Pedestrian Access.
    1. Buildings Abutting Lot Edges. All buildings that abut a lot edge (see Sec. 24.06.085-P) are subject to the following regulations:
       1. All building types and individual ground-story commercial establishments must provide a pedestrian entrance along the lot edge that provides both ingress and egress, operable to residents or customers. This requirement expressly applies to individual dwelling units within an attached house building.
       2. Additional entrances off another street, an open space, or internal parking area are also permitted.
       3. If a building abuts a lot edge along more than one public street, the required pedestrian entrance must face North Avenue.
       4. All required entrances must provide safe and convenient pedestrian pathways from the adjacent public sidewalk. Pathways that exclusively serve individual residential units must have a minimum width of 3 feet. All other pathways must have a minimum width of 5 feet.
    2. Buildings Not Abutting Lot Edges. All buildings that do not abut a lot edge are subject to the following regulations:
       1. Buildings and individual ground-story commercial establishments must provide safe and convenient pedestrian pathway from their required pedestrian entrance to a public sidewalk. This requirement expressly applies to individual dwelling units with an attached house building.
       2. Pathways that exclusively serve individual residential units must have a minimum width of 3 feet. All other pathways must have a minimum width of 5 feet.
       3. The total combined length of the pedestrian pathway from the entrance to the sidewalk may not exceed 150% of the straight line distance from the entrance to the closest public sidewalk.
19. Building Design.
    1. Applicability. The building design regulations of this section apply to all allowed building types except detached houses and two-unit houses, unless otherwise expressly stated.
    2. Purposes. The building design regulations of this section are intended to improve the physical and aesthetic quality of buildings, activate the pedestrian environment and maintain and protect the character of MID districts.
    3. Exterior Wall Finish Materials. The following exterior wall finish materials must be used on at least 80% of all street-facing building facades, not including building foundations, non-glass window components, and doors:
       1. Brick, including full-depth and half-depth masonry brick, but not simulated brick veneers; or
       2. Stone, including unpainted natural stone, unpainted cast stone having the appearance of natural stone, and unpainted terracotta.
    4. Vertical Delineation of Building Stories. The first one or 2 stories of every vertical mixed-use and commercial building must be delineated from the stories above through the use of cornice lines, horizontal shadow lines, fenestration and other forms of architectural detailing.
    5. Building Articulation and Massing. In order to avoid large expanses of flat (one-dimensional) exterior walls along sidewalks, building facades over 50 feet in length along a street, including abutting attached house dwelling units, must incorporate wall projections or recesses a minimum of 12 inches in depth. The combined length of such recesses and projections must constitute at least 20% of the total façade length along the public street.
    6. Rooflines. Building roof lines along street-facing facades must change at least once every 200 feet of facade length. This change must occur for a minimum length of 20 feet and be accomplished through at least one of the following:
       1. A change of roof parapet wall height and material;
       2. A change in roof cornice design;
       3. A change in the number of stories;
       4. A change in roof shape.
    7. Facade Length. Street-facing building facades may not exceed 300 feet in length along any single street.
20. Parking.
    1. Parking Location.
       1. Access to off-street parking spaces serving attached houses must come from alleys or shared driveways located in street side or rear yard. Access to off-street parking spaces serving all other building types must come from alleys or driveways.
       2. Off-street parking may not be located between a public street and a principal building's front facade. On lots with more than one street frontage, the front of the lot is deemed to be North Avenue.
       3. Off-street parking spaces located within the ground-story of any building may not be located within 20 feet of a North Avenue-facing building facade that abuts a lot edge. This provision does not apply to the street-side facade of detached houses, two-unit houses, semi-detached houses or attached houses.
21. PUD Overlays. After August 28, 2019, no new /PUD overlay districts may be established on property classified in a MID district. Existing /PUD overlay district regulations that apply to property classified in a MID district may be amended as long as such amendment does not expand the /PUD overlay district boundary in existence on August 28, 2019.
