ADMINISTRATION RECOMMENDATION
The Administration recommends that the City Commission adopt the Ordinance.
BACKGROUND
On February 11, 2015, at the request of Commissioner Joy Malakoff, the City
Commission referred an Ordinance Amendment to the Land Use and Development
Committee (ltem C4G), pertaining to additional restrictions and an increase in fees for
single family lot split applications.
On April 8,2015, the Land Use Committee recommended that the attached Ordinance
Amendment be referred to the Planning Board. On May 6, 015, the City Commission, at
the request of Commissioner Malakoff, referred the proposed ordinance to the Planning
Board (ltem C4A).
ANALYS!S
Any application for a division of land/lot split requires the review and approval of the
Planning Board, in accordance with the procedures and review criteria outlined in the
City Code [Section 118-321(B)]:
Review Criteria. ln reviewing an application for the division of lot and lot split, the
Planning Board shall apply the following criteria:
1. Whether the lots that would be created are divided in such a manner that they are in
compliance with the regulations of these land development regulations.
355
Commission Memorandum
Ordinance Amendment - Single Family Home Development Regulations for Lot Splits
September 2, 2015 Page 2 of 2
2. Whether the building site that would be created would be equal to or larger than the
majority of the existing building s/Tes, or the most common existing lot size, and of
the same character as the surrounding area.
3. Whether the scale of any proposed new construction is compatible with the as-built
character of the surrounding area, or creates adverse impacts on the surrounding
area; and if so, how the adverse impacts will be mitigated. To determine whether
this criterion is satisfied, the applicant shall submit massing and scale sfudies
reflecting structures and uses that would be permitted under the land development
regulations as a result of the proposed lot split, even if the applicant presently has no
specific plans for construction.
4. Whether the building sffe that would be created would result in existing structures
becoming nonconforming as they relate fo sefbacks and other applicable regulations
of these land development regulations, and how the resulting nonconformities will be
mitigated.
5. Whether the building site that would be created would be free of encroachments from
abutting buildable sites.
6. Whether the proposed lot split adversely affects architecturally significant or historic
homes, and if so, how the adverse effects will be mitigated. The Board shall have
the authority to require the full or partial retention of structures constructed prior to
1942 and determined by the Planning Director or designee to be architecturally
significant under section 142-108 (2)
As further expressly outlined in Section 118-321(C), the Planning Board also has the
authority to restrict the size of new homes resulting from a lot split application:
Final decision. ln granting a division of land/lot split, the planning board may
prescribe appropriate conditions and safeguards, including but not limited to a
condition restricting the size of new structures to be built on the resulting lots, based
upon the application's safisfacfion of and consistency with the criteria in subsection B
above, and the board's authority under section 1 18-51 .
Last year the Code was amended to also require that new homes resulting from
approved 'Lot Split' applications be required to obtain approval from either the Historic
Preservation Board (HPB) or Design Review Board (DRB), as applicable.
As part of the review of each application for a lot split, staff prepares an analysis of
similar lots within the immediate neighborhood. For example, if the lot split application is
for a waterfront lot, only existing waterfront lots are included as part of the analysis.
Typically 15-20 properties are reviewed, including the average, median, and mode of the
lot sizes, as well as the existing unit sizes for each of the comparison properties.
The source of the data is the Miami Dade County Property Appraiser's Office, which
adjusts the size of structures by increasing or adjusting the stated square footage for
outdoor covered areas such as loggias, covered patios, etc. and for non-air-conditioned
garages. As per the City's definitions, in most cases these items are excluded from unit
size calculations. ln the Data Analysis performed by staff, a "20o/o allowance" is used to
take into consideration a reasonable accommodation for future renovations and

additions for existing homes, with the exception of homes which are already near or at
the maximum square footage allowed as per City Code. Planning staff normally then
recommends that the size of a new home not exceed 25o/o of the average of the existing
homes in the immediate area.
ln order to help ensure that new construction is compatible with existing neighborhood
character, especially when an existing pre-1942 architecturally significant home is
demolished, the proposed Ordinance would place a limit on the maximum lot coverage
for any one (1) story home at 4Oo/o of the lot area and for new two story homes resulting
from a lot split application at 25o/o, as well as cap the unit size for any new home at 40o/o
of the lot area or such lesser number, as determined by the Planning Board, in the
following instances:
1. When the new lots created do not follow the lines of the origina! platted
lots; or
2. When the lot being divided contains an architecturally significant, pre-1942
home, that is proposed to be demolished.
Currently, the maximum lot coverage that can be permitted is 50% for one story homes
and 30% for two-story structures and the maximum unit size is 50%.
For comparison purposes, stalT has included a massing study (attached) comparing the
current maximum requirements for unit size and lot coverage with the potential reduced
requirements. The top graphic shows front and rear views of the same home with a lot
coverage of 30o/o and a unit size of 50% of the lot area. The darker shaded portions of
the home denote areas that would have to be removed to bring the lot coverage down to
25o/o and massing down to 40o/o. The bottom graphic shows the home with the additional
massing removed to comply with the proposed requirements.
PLANNING BOARD REVIEW
On June 23, 2015, the Planning Board (by a 6-0 vote) transmitted the proposed
Ordinance to the City Commission with a favorable recommendation.
FISCAL IMPACT
ln 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 evaluated 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.
SUMMARY
