(a) Minimum Required Yards. All garages and carports which have the main entrance perpendicular to a street will have a minimum yard of 20 feet adjacent to that street. Garages and carports for which the main entrance is not perpendicular to the street from which access is gained will have a driveway at least 20 feet in length from the edge of the main entrance of the garage or carport to the edge of the property line abutting the street from which access is obtained.

(b) Design. All garages and carports, be they attached to or detached from the principal building(s) on a lot, must be designed to meet at least one (1) of the following criteria:

(i) the setback for the garage or carport from an adjacent street is equal to or greater than some other part of the facade;

(ii) the garage or carport is no more than 60% of the width of the facade on which the vehicular entrance to the garage or carport is located;

(iii) the floor level of the garage or carport is four (4) feet or more below the grade of the street from which access is gained at the driveway to said garage or carport;

(iv) the vehicular entrance to the garage or carport is placed at more than a 45-degree angle to a lot line abutting an adjacent street; or

(v) an architectural feature(s), such as a bedroom-size window (5.7 square feet, 2 feet in height, 2.5 feet wide), pedestrian door, or balcony, is installed in a garage wall facing an adjacent street or said architectural feature is installed on a wall or dormer located directly above the vehicular entrance to the garage or carport and within 10 horizontal feet of the vehicular entrance to the garage or carport.

As used in this subsection, “adjacent street” means a street that abuts a lot line of the lot on which the garage or carport is located.

(a) Maximum Building and Lot Coverage. For a lot in a high-density residential district contiguous to or across a street or alley from a low-density residential district, the maximum portion of the lot area that may be occupied by buildings and structures will be 40%.

(b) Minimum Required Yards.

(c) Balconies. For a lot in a high-density residential district, balconies located within 50 feet of a low-density residential district will be prohibited on walls that face a low-density residential district. A wall is facing a district when it is visible from said district and it is angled less than 90 degrees in relation to the boundary of said district.

(d) Screening and Landscaping. Screening and landscaping of lots in a high-density residential district that abut a low-density residential district are required as described in PCC 17.45.050.

(a) Setback. Buildings will be set back from the adjoining street(s) at least as far as the buildings on abutting residentially zoned lots fronting on said adjoining street(s).

(b) Orientation and Entrances. Buildings must be oriented to the fronting street so that the main entrance(s) is plainly visible from said street.

(c) Building Coverage. The maximum portion of the lot area that may be occupied by buildings or structures will be 125% of the largest building coverage for buildings or structures on any of the abutting occupied residentially zoned lots that adjoin the same street as the lot on which the infill development is established.

(d) Building Height. The maximum height of a building or structure will be 125% of the greatest building height for a building or structure on any of the abutting occupied residentially zoned lots that adjoin the same street as the lot on which the infill development is established.

(e) Roof Pitch. The roof pitch for buildings or structures will be within the range of 75% to 125% of the average roof slope for buildings on abutting occupied residentially zoned lots that adjoin the same street as the lot on which the infill development is established.

(f) Modification of Standards. In the event that an owner can clearly demonstrate that, due to environmental or physical constraints, or due to exceptional circumstances associated with an abutting lot(s), it is appropriate for the standards of this subsection to be modified, the Director of Community Development may grant an administrative variance in accordance with Chapter 17.130 PCC to so modify one or more of the standards herein, provided all other applicable criteria for granting an administrative variance are met.
