A.
Except as otherwise provided by this chapter, an accessory structure
shall not be located in the front yard or front setback of any parcel
(as defined by this chapter) unless the accessory structure is located
at least 100 feet from the front property line and/or side street
line.
B.
An accessory structure may be located no closer than five feet from
the side or rear property line of any conforming or legal nonconforming
parcel.
D.
Temporary fencing used primarily for construction projects and soil
erosion protection shall not be used for permanent residential or
commercial fencing. This type fencing includes, but is not limited
to, such fencing as the bright fluorescent orange fencing and the
solid black fencing.
A.
Accessory structures.
(1)
Accessory structures or accessory uses shall be limited and located
on the same lot with the principal structure or use to which they
are necessary.
(2)
Any accessory structure attached to a principal structure, including
attachment by means of a breezeway or roof passage, shall comply with
the requirements of this chapter concerning principal structures.
All other accessory structures shall conform to the requirements for
accessory structures in the district in which they are located.
(3)
In an AC, AR, RMH, RM, RS5, or RS1 Residential District, an accessory
structure on the same lot with a residential use may not be used for
residential purposes except properly approved ECHO housing or a properly
approved accessory dwelling unit.
(4)
An accessory structure may dominate the area of the principal structure
by not more than 10%. The total square footage of both the principal
and accessory structures shall be calculated using the definition
of floor area in this chapter with the inclusion of attached garages
and covered porches.
(5)
A noncommercial antenna structure or satellite dish may be authorized
as an accessory structure in any residential district, provided that:
(a)
The height of the structure does not exceed the lesser of:
(b)
The setback for the central vertical portion of the antenna
structure is at least 10 feet from each property line for a structure
up to 35 feet high, and 10 feet plus one additional foot for each
three feet in excess of 35 feet for a structure over 35 feet high:
and
(c)
Each rigid radiating element of an antenna structure is set
back at least 10 feet from any property line; and
(d)
The construction is of a type required by the Division of Inspections
and Enforcement to form a safe and durable structure.
B.
Street frontage.
(1)
No lot may be created without adequate street frontage, and such
lots shall be determined to be unbuildable.
(2)
Except as provided in a specific zoning district, a structure may
not be used in whole or in part for residential purposes unless the
lot in which it is located:
(3)
No more than one structure used in whole or in part for residential
purposes shall be permitted for each frontage or easement, except
that a common easement of access measuring at least 40 feet wide may
be provided for two or more structures.
(4)
On a corner lot, the front street shall be the street with the shorter
street frontage.
C.
Setbacks.
(1)
Any setback or other open space allocated to a structure shall be
located on the same lot as the structure.
(2)
Except as provided in this subsection, required setback and open
space shall be unobstructed and open to the sky.
(3)
Architectural features for principal structures, such as windows,
sills, chimneys, bilco doors, egress windows, cornices, eaves, or
bay windows may project no more than three feet into a required yard
area and no closer than five feet from any lot line. The sum of the
bay window projections on a wall may not exceed 1/4 of the length
of the wall.
(4)
An open unenclosed porch, patio, or deck may project into required
side and rear setback areas, provided that all such structures shall
observe a minimum setback of 10 feet from all side and rear property
lines or may extend into the required front yard setback no more than
40% of the required front yard setback, and no closer than 15 feet
to the right-of-way line. Furthermore, if a nonconforming front yard
setback exists, created by the lawful construction of the principal
structure, the 40% shall be determined based on the legal nonconforming
front yard setback. This section does not extend to properties where
variances were granted for relief of the front yard setback. All open
unenclosed porches, patios, and decks that project into the required
setback shall be constructed at grade or at the first-floor level
of the building. Any enclosed porch, patio, or deck, or porch having
a roof and capable of being enclosed, shall be considered a part of
the structure in the determination of the size of the setback or the
amount of lot coverage, except that a porch, patio, or deck with only
a roof and no walls of any type may project into the required front
setback by no more than six feet. Any porch, patio, or deck, both
enclosed and unenclosed, shall not occupy more than 30% of the minimum
required side or rear yard setback area.
(5)
Notwithstanding any provision to the contrary, if the average front
yard setback of structures located on either side of a lot differs
from the minimum setback required by this chapter, the setback shall
approximate the average setback of the next nearest structures.
(6)
Handicapped ramps open, unenclosed and not covered by a roof or canopy
shall maintain a five-foot setback from the front, side, and rear
property lines.
(7)
Fences, walls, and hedges.
(a)
The setback requirements of this chapter do not prohibit an
otherwise lawful fence or wall, if the fence or wall does not impair
visibility at any access to a public road and does not conflict with
the provisions of this section.
(b)
Except for patio homes, an ornamental fence or wall not more
than four feet in height may project into or enclose any required
front or side setback to a depth from the street line equal to the
required depth of the front setback. Ornamental fences or walls may
project into or enclose other required setbacks, provided that such
fences and walls do not exceed a height of seven feet.
(c)
A structure, fence, wall, hedge or planting more than two feet
high as measured above the street surface at the nearest edge of the
pavement may not be erected, placed or maintained on a corner lot
within a triangular area formed by the intersecting street lines.
The sides of the triangular area shall measure 25 feet from the point
where the street lines will intersect if extended to the apex. The
provisions of this subsection do not apply to trees more than six
feet apart or to existing trees, provided that all branches are located
at least six feet above the ground.
(8)
Recreation facilities (residential and nonresidential).

including any deck or patio is at least 10 feet from each lot line.
(b)
Each community recreational facility, such as a tennis court,
basketball court or at-grade swimming pool, shall be located at least
30 feet from each lot line, structure, or dwelling unit, 25 feet from

necessary to accomplish the purpose intended and in no event more
than 15 feet above the lowest point of contact with the roof.
(2)
Roof features, such as water tanks, cooling towers, air-conditioning
units, elevator shafts and bulkheads, shall be enclosed within the
walls of the structure and designed in harmony with the main walls
of the structure on which they are located.
(3)
A public governmental building, place of worship or hospital may
be erected to a greater height than otherwise permitted, provided
that the front, side and rear setbacks are increased not less than
one foot for each foot by which the structure exceeds the height limitation
established for the district in which the structure is located.
(4)
Unless otherwise provided in this section, a parapet wall may extend
not more than five feet above the height limit for the district in
which it is located.
