Districts
A = 50% of the sum of the heights of the buildings , but not less than 15 feet.
B = 50% of the sum of the heights of the buildings .
C = Buildings within 100 feet of an adjoining district are limited to the height of the most restrictive of an
adjoining district.
D = 50% of the sum of the heights of the buildings , but not less than 25 feet.
Principal Structure Minimum Yard ( Setback ) Requirements: Table 2.1, below, provides the
minimum yard requirements for principal structures on conforming lots of record in base
zoning districts. The following shall apply for all other lots :
a. Corner Lots : Corner lots shall have front yards along each street frontage . The other
yards shall be considered side yards . See LDC section 2.03.01 for Estates setbacks .
b. Nonconforming Lots of Record : Minimum yard requirements for nonconforming lots
of record are provided in LDC section 9.03.03 A.
Table 2.1 - TABLE OF MINIMUM YARD REQUIREMENTS
(SETBACKS) FOR BASE ZONING DISTRICTS
Note as to setback line measurement: minimum setback lines are typically measured from the legal
boundary of a lot, regardless of all easements burdening
a lot , with the exception
of easements that
comprise a road right-of-way where the minimum setback line is to be measured from
the road right-of-
way easement line.

Overlay 'See table of special design requirements for the applicable overlay district located in the
Districts , appropriate section for that district in chapter 4.
MH District - additional yard requirements: side yard setback from a public road that is external to the
boundary of the park = 50 ft.; the minimum setback on any side from the exterior boundary of the park =
15ft.
2 TTRVC District - additional yard requirements: setback from exterior boundary of park = 50 ft.; setback
from an external street = 50 ft., setback from an internal street = 25 ft.; setback from any building or other
structure = 10 ft.
3 C-3 District - minimum setback on any side that is waterfront = 25 ft.; setback for marinas = none.
4 C-4, C-5 and I Districts - minimum setback on any side that is waterfront = 25 ft.;
setback for marinas = none; setback on any side adjacent to a railroad right-of-way = none
5 Any non -conforming platted lot of record in the CON District that existed before November 13, 1991
will be subject to the following standards:
Front yard: 40 feet.
Side yard: ten percent of the lot width, but no more than 20 feet on each side.
Rear Yard: 30 feet.
a = 50% of the building height, but not less than 15 feet
b = 50% of the building height, but not less than 30 feet
c = 50% of the building height, but not less than 25 feet
d = 50% of the building height, but not less than 25 feet. Structures 50 feet or more in height = 25 feet
plus one additional foot of setback for each foot of building height over 50 feet.
e = the total of all side yard setbacks shall equal 20% of the lot width, with a maximum of 50 feet. No side
yard shall be less than 10 feet. Alternative dimensions may be possible when approved through a unified
plan of development involving one or more lots under common ownership where the yard requirements
are met for the unified site but not necessarily for each parcel within the unified site.
f = the yard requirements shall be equal to the most restrictive adjoining district.
x = for principal structures: 50 feet from all property lines; for accessory structures: 25 feet from all
property lines.
B. Open space requirements. Usable open space shall be provided as follows, except as required in
the Rural Fringe Mixed Use District within the Future Land Use Element of the Growth
Management Plan.
1. In residential developments , at least 60 percent of the gross area shall be devoted to usable
open space . This requirement shall not apply to individual single-family lots less than 2.5
acres in size.
2. In developments of commercial, industrial and mixed use including residential, at least 30
percent of the gross area shall be devoted to usable open space . This requirement shall not
apply to individual parcels less than five acres in size.
3. Historical/archaeological resources that are to be preserved may be utilized to satisfy required
setbacks , buffer strips or open space up to the maximum area required by development
regulations. Conservation of such historic or archaeological resources shall qualify for any open
space requirements mandated by the development regulations.
C. Specific Requirements for Uses Involving Shopping Carts.
When the operating characteristics of a duly authorized business require the utilization of shopping carts
by customers, provision shall be made for outside storage areas to be illustrated on a site development
plan , and said shopping carts shall be collected at the close of business each day and stored at the front
of that business establishment. It shall be the responsibility of the merchant to collect any and all
shopping carts that stray from the premises upon which they are intended to be utilized. A name -plate on
a shopping cart shall be prima facia evidence of ownership.
D. Exemptions and exclusions from design standards.
The height limitations contained in LDC subsection 4.02.01 A. Table 2. Building Dimension
Standards for Principal Uses in Base Zoning Districts do not apply to infrastructure in support of
the building , such as mechanical penthouses, elevator shafts, stair shafts, mechanical
equipment, mechanical screening, spires, belfries, cupolas, flagpoles, antennas,
communications towers , water tanks, fire towers when operated by a branch of government,
ventilators, chimneys, feed storage structures , silos, windmills, airport control towers , or
other appurtenances placed above the roof level and not intended for human occupancy or for
commercial purposes as provided below:
a. Structural elements shall be no higher than necessary to accomplish the purpose it is
intended to serve.
b. The aggregate area of structures or appurtenances shall not exceed one-third the area of
the supporting roof.
c. Where this section conflicts with section 5.05.08, the provisions of section 5.05.08 will
control.
d. The heights of these structures or appurtenances thereto shall not exceed any height
limitations prescribed by the Federal Aviation Agency or airport zoning regulations within
the flight approach zone of airports . (See section 2.03.07 C.).
In instances where off- street parking is provided within the principal structure , the County
Manager or designee may waive the maximum height requirements to the extent necessary to
permit off- street parking within the principal structure , provided however: (1) the number of
off- street parking spaces required by this LDC for the use involved may not be reduced; (2) the
waiver in height shall not be greater than that necessary to provide for the off- street parking
within the principal structure , with a maximum of two parking levels; (3) the waiver of the
maximum height requirements are compatible with the uses on adjacent properties; and (4) for
each off- street parking space permitted within the principal structure for which the maximum
height waiver is granted, 300 square feet of additional open space beyond that which is
otherwise required by this LDC shall be provided.
Every part of every required yard shall be open and unobstructed from thirty (30) inches above
the general ground level of the graded lot upward to the sky except as hereinafter provided or
as otherwise permitted in this LDC.
4. Sills and other architectural and design treatments shall not project over twelve (12) inches into
a required yard .
Movable awnings shall not project over three (3) feet into a required yard , provided that where
the yard is less than five (5) feet in width the projection shall not exceed one-half (1/2) the width
of the yard .
6. Window- or wall -mounted air conditioning units, chimneys, fireplaces, bay windows, or pilasters
shall not project over two (2) feet into a required yard .
Fire escapes, stairways, and balconies which are unroofed (except as otherwise permitted
within this section) and unenclosed shall not project over five (5) feet into a required side or rear
yard and three (3) feet into a front yard of a multi -family dwelling , hotel or motel and not
over three (3) feet into a required front, side or rear yard of a single-family residential dwelling
. Regardless of the extent of encroachment, the minimum requirement for separation of
structures shall be maintained.
8. Hoods, canopies, or roof overhangs shall not project over (3) three feet into a required yard ,
but shall not come closer than one (1) foot to the lot line .
9. Fences, walls and hedges, subject to section 5.03.02, ground mounted air conditioners,
unenclosed pool equipment and well pumps, are permitted in required yards , subject to the
provisions of section 4.06.00. This includes air conditioners that are ground mounted and those
required to be elevated to meet flood elevation, including their supporting structures , provided
the minimum separation of structures is maintained.
10. Cornices, eaves or gutters shall not project over three (3) feet into a required yard , provided
that where the required yard is less than six (6) feet in width, such projection shall not exceed
one-half ('/z) the width of the yard .
11. Except as otherwise provided by this LDC, when lots on both sides of an undeveloped
recorded lot contain a residential structure whose front yard setback is less than is now
required, the average of the setbacks of the two (2) contiguous developed lots shall serve to
establish the minimum front yard requirement for the vacant lot.
12. In commercial, industrial and multi -family residential developments , carports which are open
on all sides may encroach into the required yards provided they do not encroach into the
required landscape buffers , as required by this LDC; and furthermore, if the landscaping is
deficient where the carports are proposed, the landscaping must be upgraded to comply with
the LDC requirements to the greatest extent possible prior to the issuance of a building permit
for said carports. This shall be accomplished by a site development plan amendment or a site
improvement plan approval.
13. Permanent emergency generators may be placed within the rear yard with a 10 -foot rear yard
setback. Permanent emergency generators may encroach into side yards up to 36 inches.
Generators are not permitted to encroach into required front yards. Above -ground fuel tanks for
the generators are subject to the same setbacks; however, underground tanks are not subject
to setback requirements. In order to reduce noise during required routine exercising of the
generators, this exercising is restricted to operating the generator for no more than 30 minutes
weekly during the hours of 9:00 a.m. to 5:00 p.m. and shall not exceed sound level limits for
Manufacturing and Industrial uses as set forth in Ordinance 90-17, the Noise Ordinance, as
amended. All permanent emergency generators must be equipped with sound attenuating
housing to reduce noise.
a. Facilities with fuel pumps. Permanent emergency generators and related fuel storage
installed at existing facilities with fuel pumps may encroach into any required side or rear
yards, provided the encroachment does not create a hazard to pedestrian or vehicular
traffic.
b. Assisted living facilities and nursing homes. Permanent emergency generators and related
fuel storage installed at existing assisted living facilities or nursing homes that are subject
to LDC section 5.05.04 E. may encroach into any required side or rear yards or buffers,
provided the encroachment does not create a hazard to pedestrian or vehicular traffic.
