A proposed or existing rule is an 55 invalid exercise of delegated legislative authority if any one 56 of the following applies: 57 (e) The rule is arbitrary or capricious. A rule is 58 arbitrary if it is not supported by logic or the necessary 59 facts; a rule is capricious if it is adopted without thought or 60 reason or is irrational; or 61 (f) The rule imposes regulatory costs on the regulated 62 person, county, or city which could be reduced by the adoption 63 of less costly alternatives that substantially accomplish the 64 statutory objectives ; or 65 (g) The agency has issued a guidance document or other 66 statement interpreting a statute without express s tatutory 67 delegation to issue such guidance . 68 69 A grant of rulemaking authority is necessary but not sufficient 70 to allow an agency to adopt a rule; a specific law to be 71 implemented is also required. An agency may adopt only rules 72 that implement or interpret t he specific powers and duties 73 granted by the enabling statute. No agency shall have authority 74 to adopt a rule only because it is reasonably related to the 75 HB 305 2025 CODING: Words stricken are deletions; words underlined are additions. hb305-00 Page 4 of 20 F L O R I D A H O U S E O F R E P R E S E N T A T I V E S purpose of the enabling legislation and is not arbitrary and 76 capricious or is within the agency's cla ss of powers and duties, 77 nor shall an agency have the authority to implement statutory 78 provisions setting forth general legislative intent or policy. 79 Statutory language granting rulemaking authority or generally 80 describing the powers and functions of an ag ency shall be 81 construed to extend no further than implementing or interpreting 82 the specific powers and duties conferred by the enabling 83 statute. 84 Section 2.

An agency may adopt only rules 90 that implement or interpret the specifi c powers and duties 91 granted by the enabling statute. An agency may not adopt any 92 rule or issue any guidance document unless the agency has been 93 expressly granted the power to do so by a specific statutory 94 delegation. No agency shall have authority to adopt a rule only 95 because it is reasonably related to the purpose of the enabling 96 legislation and is not arbitrary and capricious or is within the 97 agency's class of powers and duties, nor shall an agency have 98 the authority to implement statutory provisions sett ing forth 99 general legislative intent or policy.

The 114 statement must include a cost -benefit analysis that clearly 115 demonstrates that the projected benefits of the existing rule or 116 proposed rule exceed its projected costs. 117 (b)(a) Within 21 days after publication of the notice 118 required under s. 120.54(3)(a), a substantially affected person 119 may submit to an agency a good faith written proposal for a 120 lower cost regulatory alternative to a proposed ru le which 121 substantially accomplishes the objectives of the law being 122 implemented. The proposal may include the alternative of not 123 adopting any rule if the proposal explains how the lower costs 124 and objectives of the law will be achieved by not adopting any 125 HB 305 2025 CODING: Words stricken are deletions; words underlined are additions. hb305-00 Page 6 of 20 F L O R I D A H O U S E O F R E P R E S E N T A T I V E S rule.

Upon the submission of the 127 lower cost regulatory alternative, the agency shall prepare a 128 statement of estimated regulatory costs as provided in 129 subsection (2), or shall revise its prior statement of estimated 130 regulatory costs, and either adopt the alternative or provide a 131 statement of the reasons for rejecting the alternative in favor 132 of the proposed rule. 133 (c)(b) If a proposed rule, notice of change, or final 134 rule will have an adverse impact on small business or if the 135 proposed rule, notice of change, or final rule is likely to 136 directly or indirectly increase regulatory costs in excess of 137 $200,000 in the aggregate within 1 year after the implementation 138 of the rule, the agency shall prepare a statement of estimated 139 regulatory costs as required by s. 120.54(3)(b). 140 (d)(c) The agency shall revise a statement of estimated 141 regulatory costs if any change to the rule made under s. 142 120.54(3)(d) increases the regulator y costs of the rule. 143 (e)(d) At least 21 days before filing the rule for 144 adoption, an agency that is required to revise a statement of 145 estimated regulatory costs shall provide the statement to the 146 person who submitted the lower cost regulatory alternative and 147 to the committee and shall provide notice on the agency's 148 website that it is available to the public. 149 (f)(e) Notwithstanding s. 120.56(1)(c), the failure of the 150 HB 305 2025 CODING: Words stricken are deletions; words underlined are additions. hb305-00 Page 7 of 20 F L O R I D A H O U S E O F R E P R E S E N T A T I V E S agency to prepare a statement of estimated regulatory costs or 151 to respond to a written l ower cost regulatory alternative as 152 provided in this subsection is a material failure to follow the 153 applicable rulemaking procedures or requirements set forth in 154 this chapter. 155 (g)(f) An agency's failure to prepare a statement of 156 estimated regulatory cost s or to respond to a written lower cost 157 regulatory alternative may not be raised in a proceeding 158 challenging the validity of a rule pursuant to s. 120.52(8)(a) 159 unless: 160 1. Raised in a petition filed no later than 1 year after 161 the effective date of the rul e; and 162 2. Raised by a person whose substantial interests are 163 affected by the rule's regulatory costs. 164 (h)(g) A rule that is challenged pursuant to s. 165 120.52(8)(f) may not be declared invalid unless: 166 1. The issue is raised in an administrative proceed ing 167 within 1 year after the effective date of the rule; 168 2. The challenge is to the agency's rejection of a lower 169 cost regulatory alternative offered under paragraph (b) (a) or 170 s. 120.54(3)(b)2.b.; and 171 3. The substantial interests of the person challeng ing the 172 rule are materially affected by the rejection. 173 (i) An agency shall conduct a retrospective cost -benefit 174 analysis for each adopted rule 4 years after the rule's 175 HB 305 2025 CODING: Words stricken are deletions; words underlined are additions. hb305-00 Page 8 of 20 F L O R I D A H O U S E O F R E P R E S E N T A T I V E S effective date. The analysis must compare the actual costs and 176 benefits of the rule to those projected in the initial statement 177 of estimated regulatory costs prepared under paragraph (a). 178 (j) When a rule is reviewed upon expiration pursuant to s. 179 120.55(9), the agency shall conduct a retrospective assessment 180 report comparing the initial p rojected cost-benefit analysis, 181 the retrospective analysis conducted under paragraph (i), and 182 the outcomes observed up to the time of expiration. The agency 183 shall incorporate the findings and lessons learned from this 184 comparison into the standards for futu re statements of estimated 185 regulatory costs and apply them to similar rules. 186 (2) A statement of estimated regulatory costs shall 187 include: 188 (g) In the statement or revised statement, whichever 189 applies, a description of any regulatory alternatives submitt ed 190 under paragraph (1)(b) (1)(a) and a statement adopting the 191 alternative or a statement of the reasons for rejecting the 192 alternative in favor of the proposed rule. 193 (h) All documentation, assumptions, methods, and data used 194 in preparing the statement of estimated regulatory costs shall 195 be published on a publicly accessible website and, where 196 relevant, in a machine -readable format readily available to the 197 public, including any supporting calculations, documents, data, 198 databases, or data tables, so that the results of the analysis 199 can be replicated. Uncertainties pertaining to these estimates 200 HB 305 2025 CODING: Words stricken are deletions; words underlined are additions. hb305-00 Page 9 of 20 F L O R I D A H O U S E O F R E P R E S E N T A T I V E S must be reported. 201 (4) Subsection (3) does not apply to the adoption of: 202 (a) Federal standards pursuant to s. 120.54(6). 203 (b) Triennial updates of and amendments to the Florida 204 Building Code which are expressly authorized by s. 553.73. 205 (c) Triennial updates of and amendments to the Florida 206 Fire Prevention Code which are expressly authorized by s. 207 633.202. 208 (5) For purposes of subsections (2) and (3), adverse 209 impacts and regulatory costs likely to occur within 5 years 210 after implementation of the rule include adverse impacts and 211 regulatory costs estimated to occur within 5 years after the 212 effective date of the rule. However, if any provision of the 213 rule is not fully implemented upon the effective date of the 214 rule, the adverse impacts and regulatory costs associated with 215 such provision must be adjusted to include any additional 216 adverse impacts and regulatory costs estimated to occur within 5 217 years after implementation of such provision. However, an agency 218 may include longer periods of review but must, at a minimum, 219 provide a cost-benefit analysis that projects the first 5 years 220 after the rule goes into effect. If a discount rate is used in 221 the analysis, its use must be justified. The agency must also 222 provide an analysis without the use of discount rates. 223 Section 4.
