Note 1.1. Projections in QMDS. See QMDS Schedule.
Note 1.2. Porch In Front Yard. On a building site in a residential district with a front yard depth of 20
feet or more, a porch may project up to 120 inches into the front yard if it meets all of the
following criteria:
(i) It is neither designed nor usable for motor vehicles;
(ii) The volume of the projecting part of the porch does not exceed 50 cubic feet per foot of front
street line (Example: the maximum projecting volume on a 52%-foot wide site would be 50 cubic
feet x 52.5, or 2,625 cubic feet).
(iii) The porch's outside perimeter is open and unobstructed, except for the following features: (a)
Ordinary window screens. (b)A solid or partially open safety rail not higher than 3.5 feet above
the porch floor. (c) Supporting vertical columns, if the total width of the outer faces of the
columns does not exceed either 50% of the outside perimeter of the porch or 25% of the
theoretical outside perimeter of a maximum-sized porch. The width of a column is measured at
its thickest point above 3.5 feet above the porch floor. The "maximum-sized porch"is 120
inches deep and extends from one side yard line to the other, but it is limited by the open area
requirement for the front yard. The "outside perimeter"of a porch is the portion of the perimeter
out in the front yard; it does not include the portion of the perimeter adjacent to a building or
lying along the front setback line.
(iv) At no point in the front yard does the porch have a height greater than the depth of the front
yard (Example: if the depth of the front yard is 20 feet, the maximum height in the front yard is
also 20 feet).
Note 2. Gas Pipeline Sites . A principal building may project into the front yard if: (a)the building site
includes land in the rear of the building site subject to a gas transmission easement thirty feet or
wider that is actually traversed by a gas transmission (not distribution) pipeline; (b) no part of
the principal building, except items that are otherwise allowed to project into front setback
areas, is within twenty feet of the front street line; and (c)The entrance to garage space is not
closer than thirty feet to the front street line.
Note 3. Buildings In Rear Yard or SF Bufferyard. A building may be located in a rear yard or SF
Bufferyard if it meets all of the following criteria: (a) No part of the building may be closer than
five feet to the rear property line (or to any SF District, if in a SF Bufferyard). (b)Within ten feet
of another building site in an SF District(whether on the side, rear or otherwise), it may have no
window, door or other opening above the ground floor(and facing the property line of the other
building site), except for translucent(but not transparent), non-operable openings. (c) Space in
any projecting building may only be used for single-family(detached) use. (d)A principal
building may not project unless the ground floor of the projecting part is at least 51 percent
garage space, and there is no more than 600 square feet of building space, other than garage
space, in the projecting part). See garage restrictions in Article 10.
Note 4. Railway/Gas Sites . A building may be located in a rear yard if: (a)the yard abuts land used
for railway purposes or gas transmission (not distribution) pipeline purposes; (b)the building
does not occupy any area subject to a utility easement or drainage easement, unless each
entity claiming an interest in the easement grants its consent or acquiescence to the
encroachment; and (c) the building is an accessory building. If these criteria are met, the normal
restrictions for rear yard projections do not apply(see notes above).
Note 5. Garages in Side Yards . A building may project toward an interior side property line(not a
side street line) if it meets all of the following criteria: (a) No part of the building may be closer
than three feet to the side property line. Exception: Eaves may be as close as two feet. (b)The
projecting part may only contain garage space and space above the garage (plus stairway and
eaves). (c)Any projecting part must be at least seventy feet from the front street line. (d)Within
ten feet of another building site in an SF District(whether on the side, rear or otherwise), the
building may have no window, door or other opening above the ground floor(and facing the
property line of the other building site). Exception:There may be translucent(but not
transparent), non-operable openings.
Note 6. Equipment in Rear or Side Yard.
REAR YARD: Indicated equipment may project into a rear yard only if: (a)separating the
equipment from any building site across the rear lot line, there is a solid wall at least one
foot higher than the highest part of the equipment; (b) if the equipment occupies any part of
an easement under the control of the City, the City has issued a separate acquiescence or
consent to the occupancy of the easement; (c)there has been formally granted to the city
any utility easement deemed necessary by the City's chief utility official; (d)the base of the
equipment is not higher than 14 inches above the ground ( Exception : The base may be
elevated to the minimum level of the lowest floor of the principal building, as established by
the City's flood damage prevention ordinance, if that level is higher than 14 inches above
the ground.); and (e) if located within five feet of any property line, the equipment is fully
encased in a sound-absorbing cabinet or is otherwise designed and operated to comply
with the City's noise regulations; see Chapter 54 of the Code of Ordinances.
SIDE YARD: Indicated equipment may project into an interior or street side yard (but not closer
than three feet to a property line)only if it is fully encased in a sound-absorbing cabinet, or
is otherwise designed and operated to comply with the City's noise regulations; see
Chapter 54 of the Code of Ordinances. However, equipment replacing older equipment in a
side yard may project as close as 18 inches to a property line, if the fire marshal
determines that such projection will not significantly interfere with emergency access,
either on the same site or on another site.
NEW AND REPLACEMENT EQUIPMENT: These rules apply to all new and replacement
equipment. Exception: If older equipment was lawfully installed on an elevated structure in
a rear yard, replacement equipment may be installed on the same structure. If the older
equipment was lawfully installed without the required separating wall, the wall must be
provided, but it may be either solid or at least 50% solid (e.g., lattice). All other rules apply.
Note 7. Basketball Goals . No part of the equipment may be closer than ten feet to any street line.
Note 8.1 Fences. Fences may project into front and side yards to the extent expressly required or
authorized by city ordinance(e.g., provisions in Chapter 18 of the Code of Ordinances;
provisions in PDD schedules for front fences). Also in the Code of Ordinances, there are: (i)
requirements for emergency portals in fences (Chapter 18) and (ii) restrictions on fences,
certain "fence-like hedges" and other things in visibility areas (Chapter 82). In a QMDS low
fences (3.5 feet or lower) may be located anywhere, if made of ornamental metal or pickets.
Note 8.2. Fence-like hedges. Fence-like hedges within the front yard (setback) of a building site
containing no principal building are prohibited. This provision applies to all adjacent side yard
building sites and rear through building sites. Visibility triangles and visibility areas, as defined
by this ordinance, are subject to further restrictions as contained in Chapter 82 of the Code of
Ordinances.
Note 9. Swimming Pools . Except as specifically allowed by another ordinance of the City governing
setbacks for swimming pools and appurtenances.
Note 10. Lampposts . Maximum diameter of projecting posts is six inches; maximum height is eight
feet.
Note 11. Rotated Corner Fences . Notwithstanding any other provision of this ordinance or any other
ordinance, no fence is allowed in the side street yard of a rotated corner building site (SF-1
District), except for temporary construction fences required by Chapter 18 of the Code of
Ordinances.
Note 12. Front Fences in Townhouse Districts . On a building site in a townhouse district(including
the TH and PDD-TH districts), there may be fences in the front yard, but not higher than seven
feet and not closer than five feet to the front street line. More permissive provisions elsewhere
may also apply.
Note 13. Old Stock Housing. The ZBA may issue a special exception to authorize projection of
buildings and attached structures into a side yard, rear yard or an SF Bufferyard, if the ZBA
determines: (i)the projection is reasonably necessary to preserve or protect old stock housing
as it then exists or as it may be proposed to be remodeled or expanded (up to a total gross floor
area, for all buildings on the site, that does not exceed the greater of 3,400 square feet or 200%
of the gross floor area of all the buildings on the site when the principal building was built,
before 1980); and (ii)there will be no substantial adverse impact upon nearby properties.
