ADM!NISTRATION RECOMMENDATION
The Administration recommends that the City Commission adopt the attached
Ordinance.
BACKGROUND
On February 12, 2014, the Commission adopted comprehensive revisions to the singlefamily development regulations. on September 30, zoj4, at the request of
Commissioner Joy Malakoff, the City Commission referred an item to the Planning Board
and the Land Use and Development Committee (ltem C4A), pertaining to additional
refinements to the single family development regulations regarding lotloverage and
units size for Accessory Structures.
On December 10, 2014 lhe Land Use Committee discussed the proposed Ordinance
and recommended that the Planning Board transmit it to the City Commission with a
favorable recommendation.

Single Family Development Regulations - Lot Coverage and Unit Size
May 6, 2015
adopted on February 12, 2014, portions of covered terraces projecting more than 10 feet
from a building were required to be counted in the unit size calculations of the home.
This also included typical accessory structures, which often consist of a single story
cabana structure with a bathroom and an associated covered terrace area. ln-order to
create a reasonably sized outdoor terrace area, these covered terraces often project
more than 10 feet from the enclosed portion of a cabana building or accessory structure.
Covered portions projecting beyond 10 feet are required to be counted toward the unit
size.
As part of more comprehensive changes to the single family regulations, a separate
Ordinance recently adopted by City Commission clarifies tnai tnJinclusion of covered
terraces beyond 10 feet in the unit size requirements applies to the main home
building(s) only.
The subject Ordinance would place a cap on the maximum size of a covered terrace
associated with an allowable accessory structure within the required rear yard, to no
more than 2o/o of the lot area. Portions beyond 2o/o would have to be counted iowards the
unit size. Using the example of a typical 60' x 175', 10,500 SF waterfront lot, the
maximum area of any accessory structures in the required rear yard is 25% of the
required rear yard area (1,575 SF), or 393 SF. With a 2%o limitation on covered terraces,in this example the covered terrace area could not exceed 210 SF. This allows a
reasonably sized covered terrace area as part of an accessory structure that is
proportional to the size of the lot.
Lot Goveraqe
Currently outdoor covered areas that are open on at least 2 sides and not covered by afloor above are not included in the lot coverage calculations. Concerns have been
expressed with the size of these outdoor covered areas, which presently are not counted
towards the maximum lot coverage requirements of a home. While portions projecting
more than 10 feet from a building are counted in the unit size, with the new exCeption
noted above, covered areas open on all sides are not counted in either the unit size or
lot coverage of a home, regardless of their size. The subject Ordinance would place a
9?P ol the.size of the outdoor covered areas not counteO in tne overall lot coverage to2% of the lot area. Beyond this, the covered area would count toward the overall lot
coverage.
Lastly, a definition for'Pergolas' has been incorporated into the proposed legislation,
along with a limit on the size of 'skylights', which are an allowable height exception for a
single family home.
PLANNING BOARD REVIEW
On February 24, 2015, the Planning Board (by a 5-0 vote) transmitted the proposed
ordinance to the city commission with a favorable recommendation.
FISCAL IMPACT
In accordance with Charter Section 5.02, which requires that the "City of Miami Beach
shall consider the long term economic impact (at least 5 years) of proposed legislative
actions," this shall confirm that the City Administration City Administration evaluited the
long term economic impact (at least 5 years) of this proposed legislative action. The
proposed Ordinance is not expected to have a negative fiscal impact upon the City.
