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 :
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 .
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.

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 uni ed plan of development involving one or more lots under common
ownership where the yard requirements are met for the uni ed site but not necessarily for
each parcel within the uni ed 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.
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.
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.
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 ve acres in size.
Historical/archaeological resources that are to be preserved may be utilized to satisfy
required setbacks , bu er 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.
Speci c 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.
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

level and not intended for human occupancy or for commercial purposes as provided
below:
Structural elements shall be no higher than necessary to accomplish the purpose it
is intended to serve.
The aggregate area of structures or appurtenances shall not exceed one-third the
area of the supporting roof.
Where this section con icts with section 5.05.08, the provisions of section 5.05.08
will control.
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 ight approach zone of airports . (See section 2.03.07 C.).
In instances where o - 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 o - street parking within the principal structure , provided
however: (1) the number of o - 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 o - 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 o - 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.
