Sec. 15-12. Sexual Violator Residency Prohibition.
a) Findings and Intent
(i) Repeat sexual offenders, sexual offenders who use physical violence,
and sexual offenders who prey on children are sexual predators who present an extreme
threat to the public safety. Sexual offenders are likely to use physical violence and to
repeat their offenses, and most sexual offenders commit many offenses, have many
more victims than are ever reported, and are prosecuted for only a fraction of their
crimes. This makes the cost of sexual offenders victimization to society at large,while
incalculable,clearly exorbitant.
(ii) It is the intent of this Section to serve the Village's compelling interest
to promote, protect and improve the health, safety and welfare of the citizens of the
Village by creating areas around certain locations where children regularly congregate
in concentrated numbers wherein certain sexual offenders and sexual predators are
prohibited from establishing residence.
b) It is unlawful for any "Sexual Violator", as the term is defined below, to reside within
2,500 feet of any school, day care center, park or playground. The term "reside" shall not
include any temporary stay in any residential unit or any other facility as long as the temporary
stay does not exceed fifteen(15)days in any one(1) calendar year.
C) A person who violates Section 15-12(b) shall be punished by a fine not exceeding
$500.00 or by imprisonment for a term not exceeding 60 days, or by both such fine and
imprisonment.
d) For purposes of this section, a"Sexual Violator"is any person who has been convicted
of any felony sexual offense(as that term was applied and used by the state in which the person
was convicted) in any state in the United States at any time,regardless of whether adjudication
has been withheld, in which the victim of the offense was less than 16 years of age at the time
of the offense.
e) Exceptions. A person residing within 2,500 feet of any school,day care center,park,or
playground,does not commit a violation of this Section if any of the following apply:
(i) The person lawfully established the residence and reported and
registered the residence pursuant to §§775.21, 943.0435 or 944.607, Florida Statute,
prior to enactment of this Section 15-12.
(ii) The person was a minor when he/she committed the offense and was
not convicted as an adult.
(iii) The person is a minor.
(iv) The only school, day care center, park or playground within 2,500 feet
of the person's residence was opened after the person lawfully established the
residence and reported and registered the residence pursuant to §§775.21, 943.0435 or
944.607,Florida Statute.
f. It shall be a violation of the Village Code of Ordinances for a landlord or owner of
residential property in the Village to knowingly rent or lease a residence to a Sexual Violator,if
the Sexual Violator intends to reside at the property and if the property is located within 2,500
2
feet of a school, day care center, park or playground. Any person violating this provision is
subject to the code enforcement procedures set forth in Chapter 2, Article N of the Miami
Shores Village Code of Ordinances.
Section 2. That, except as amended above, all other provisions of the Code of Ordinances of Miami
Shores Village,Florida, as amended, shall remain in full force and effect.
Section 3. That all ordinances or parts of ordinances and all resolutions or parts of resolutions in
conflict with the provisions of this Ordinance are repealed.
Section 4. That if any section, clause, sentence or phrase of this Ordinance is for any reason held
invalid or unconstitutional by a court of competent jurisdiction, the holding shall not affect the validity of the
remaining portions of this Ordinance.
Section 5. That this Ordinance shall take effect immediately at the time of its passage and adoption.
