A person may57 not contract to construct, modify, alter, repair, service,58 abandon, or maintain any portion of an onsite sewage treatment59 and disposal system without being registered under part III of60 chapter 489. A property owner who personally performs61 construction, maintenance, or repairs to a system serving his or62 her own owner-occupied single-family residence is exempt from63 registration requirements for performing such construction,64 maintenance, or repairs on that residence, but is subject to all65 permitting requirements. Except as provided in paragraph (a), a66 municipality or political subdivision of the state may not issue67 a building or plumbing permit for any building that requires the68 use of an onsite sewage treatment and disposal system unless the69 owner or builder has received a construction permit for such70 system from the department. A building or structure may not be71 occupied and a municipality, political subdivision, or any state72 or federal agency may not authorize occupancy until the73 department approves the final installation of the onsite sewage74 treatment and disposal system. A municipality or political75 subdivision of the state may not approve any change in occupancyPage 3 of 33CODING: Words stricken are deletions; words underlined are additions.hb589 -04-erF 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 SENROLLEDCS/CS/CS/HB 589, Engrossed 1 2026 Legislature76 or tenancy of a building that uses an onsite sewage treatment77 and disposal system until the department has reviewed the use of78 the system with the proposed change, approved the change, and79 amended the operating permit.80(a) If the building or plumbing permit is for a single-81 family residence that requires the use of an onsite sewage82 treatment and disposal system, a municipality or political83 subdivision of the state may not require the owner or builder to84 receive a construction permit from the department for such85 system as a condition of issuing the building or plumbing86 permit. The owner or builder of the single-family residence must87 provide to a municipality or political subdivision proof that88 the owner or builder submitted an application for the onsite89 sewage treatment and disposal system when applying for a90 building or plumbing permit.91(b) If construction of the onsite sewage treatment and92 disposal system commences before the issuance of the permit for93 the onsite sewage treatment and disposal system, the property94 owner or the applicant must assume all legal, financial, and95 safety liabilities arising therefrom.96(c)(a) Subdivisions and lots in which each lot has a97 minimum area of at least one-half acre and either a minimum98 dimension of 100 feet or a mean of at least 100 feet of the side99 bordering the street and the distance formed by a line parallel100 to the side bordering the street drawn between the two mostPage 4 of 33CODING: Words stricken are deletions; words underlined are additions.hb589 -04-erF 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 SENROLLEDCS/CS/CS/HB 589, Engrossed 1 2026 Legislature101 distant points of the remainder of the lot may be developed with102 a water system regulated under s. 381.0062 and onsite sewage103 treatment and disposal systems, provided the projected daily104 sewage flow does not exceed an average of 1,500 gallons per acre105 per day, and provided satisfactory drinking water can be106 obtained and all distance and setback, soil condition, water107 table elevation, and other related requirements of this section108 and rules adopted under this section can be met.109(d)(b) Subdivisions and lots using a public water system110 as defined in s. 403.852 may use onsite sewage treatment and111 disposal systems, provided there are no more than four lots per112 acre, provided the projected daily sewage flow does not exceed113 an average of 2,500 gallons per acre per day, and provided that114 all distance and setback, soil condition, water table elevation,115 and other related requirements that are generally applicable to116 the use of onsite sewage treatment and disposal systems are met.117(e)(c) Notwithstanding paragraphs (c) and (d) (a) and (b),118 for subdivisions platted of record on or before October 1, 1991,119 when a developer or other appropriate entity has previously made120 or makes provisions, including financial assurances or other121 commitments, acceptable to the department, that a central water122 system will be installed by a regulated public utility based on123 a density formula, private potable wells may be used with onsite124 sewage treatment and disposal systems until the agreed-upon125 densities are reached. In a subdivision regulated by thisPage 5 of 33CODING: Words stricken are deletions; words underlined are additions.hb589 -04-erF 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 SENROLLEDCS/CS/CS/HB 589, Engrossed 1 2026 Legislature126 paragraph, the average daily sewage flow may not exceed 2,500127 gallons per acre per day. This section does not affect the128 validity of existing prior agreements. After October 1, 1991,129 the exception provided under this paragraph is not available to130 a developer or other appropriate entity.131(f)(d) Paragraphs (c) and (d) (a) and (b) do not apply to132 any proposed residential subdivision with more than 50 lots or133 to any proposed commercial subdivision with more than 5 lots134 where a publicly owned or investor-owned sewage treatment system135 is available. This paragraph does not allow development of136 additional proposed subdivisions in order to evade the137 requirements of this paragraph.138(g)(e) The department shall adopt rules relating to the139 location of onsite sewage treatment and disposal systems,140 including establishing setback distances, to prevent groundwater141 contamination and surface water contamination and to preserve142 the public health. The rules must consider conventional and143 enhanced nutrient-reducing onsite sewage treatment and disposal144 system designs, impaired or degraded water bodies, domestic145 wastewater and drinking water infrastructure, potable water146 sources, nonpotable wells, stormwater infrastructure, the onsite147 sewage treatment and disposal system remediation plans developed148 pursuant to s. 403.067(7)(a)9.b., nutrient pollution, and the149 recommendations of the onsite sewage treatment and disposal150 systems technical advisory committee established pursuant toPage 6 of 33CODING: Words stricken are deletions; words underlined are additions.hb589 -04-erF 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 SENROLLEDCS/CS/CS/HB 589, Engrossed 1 2026 Legislature151 former s. 381.00652. The rules must also allow a person to apply152 for and receive a variance from a rule requirement upon153 demonstration that the requirement would cause an undue hardship154 and granting the variance would not cause or contribute to the155 exceedance of a total maximum daily load.156(h)(f) Onsite sewage treatment and disposal systems that157 are permitted before June 21, 2022, may not be placed closer158 than:1591. Seventy-five feet from a private potable well.1602. Two hundred feet from a public potable well serving a161 residential or nonresidential establishment having a total162 sewage flow of greater than 2,000 gallons per day.1633. One hundred feet from a public potable well serving a164 residential or nonresidential establishment having a total165 sewage flow of less than or equal to 2,000 gallons per day.1664. Fifty feet from any nonpotable well.1675. Ten feet from any storm sewer pipe, to the maximum168 extent possible, but in no instance shall the setback be less169 than 5 feet.1706.

Any residential lot that was platted and recorded on or185 after January 1, 1972, or that is part of a residential186 subdivision that was approved by the appropriate permitting187 agency on or after January 1, 1972, and that was eligible for an188 onsite sewage treatment and disposal system construction permit189 on the date of such platting and recording or approval shall be190 eligible for an onsite sewage treatment and disposal system191 construction permit, regardless of when the application for a192 permit is made. If rules in effect at the time the permit193 application is filed cannot be met, residential lots platted and194 recorded or approved on or after January 1, 1972, shall, to the195 maximum extent possible, comply with the rules in effect at the196 time the permit application is filed. At a minimum, however,197 those residential lots platted and recorded or approved on or198 after January 1, 1972, but before January 1, 1983, shall comply199 with those rules in effect on January 1, 1983, and those200 residential lots platted and recorded or approved on or afterPage 8 of 33CODING: Words stricken are deletions; words underlined are additions.hb589 -04-erF 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 SENROLLEDCS/CS/CS/HB 589, Engrossed 1 2026 Legislature201 January 1, 1983, shall comply with those rules in effect at the202 time of such platting and recording or approval. In determining203 the maximum extent of compliance with current rules that is204 possible, the department shall allow structures and205 appurtenances thereto which were authorized at the time such206 lots were platted and recorded or approved.2072. Lots platted before 1972 are subject to a 50-foot208 minimum surface water setback and are not subject to lot size209 requirements. The projected daily flow for onsite sewage210 treatment and disposal systems for lots platted before 1972 may211 not exceed:212a. Two thousand five hundred gallons per acre per day for213 lots served by public water systems as defined in s. 403.852.214b. One thousand five hundred gallons per acre per day for215 lots served by water systems regulated under s. 381.0062.216(j)1.(h)1. The department may grant variances in hardship217 cases which may be less restrictive than the provisions218 specified in this section. If a variance is granted and the219 onsite sewage treatment and disposal system construction permit220 has been issued, the variance may be transferred with the system221 construction permit, if the transferee files, within 60 days222 after the transfer of ownership, an amended construction permit223 application providing all corrected information and proof of224 ownership of the property and if the same variance would have225 been required for the new owner of the property as wasPage 9 of 33CODING: Words stricken are deletions; words underlined are additions.hb589 -04-erF 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 SENROLLEDCS/CS/CS/HB 589, Engrossed 1 2026 Legislature226 originally granted to the original applicant for the variance. A227 fee is not associated with the processing of this supplemental228 information. A variance may not be granted under this section229 until the department is satisfied that:230a. The hardship was not caused intentionally by the action231 of the applicant;232b. A reasonable alternative, taking into consideration233 factors such as cost, does not exist for the treatment of the234 sewage; and235c. The discharge from the onsite sewage treatment and236 disposal system will not adversely affect the health of the237 applicant or the public or significantly degrade the groundwater238 or surface waters.239240 Where soil conditions, water table elevation, and setback241 provisions are determined by the department to be satisfactory,242 special consideration must be given to those lots platted before243 1972.2442. The department shall appoint and staff a variance245 review and advisory committee, which shall meet monthly to246 recommend agency action on variance requests. The committee247 shall make its recommendations on variance requests at the248 meeting in which the application is scheduled for consideration,249 except for an extraordinary change in circumstances, the receipt250 of new information that raises new issues, or when the applicantPage 10 of 33CODING: Words stricken are deletions; words underlined are additions.hb589 -04-erF 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 SENROLLEDCS/CS/CS/HB 589, Engrossed 1 2026 Legislature251 requests an extension. The committee shall consider the criteria252 in subparagraph 1. in its recommended agency action on variance253 requests and shall also strive to allow property owners the full254 use of their land where possible.255a. The committee is composed of the following:256(I) The Secretary of Environmental Protection or his or257 her designee.258(II) A representative from the county health departments.259(III) A representative from the home building industry260 recommended by the Florida Home Builders Association.261(IV) A representative from the septic tank industry262 recommended by the Florida Onsite Wastewater Association.263(V) A representative from the Department of Health.264(VI) A representative from the real estate industry who is265 also a developer in this state who develops lots using onsite266 sewage treatment and disposal systems, recommended by the267 Florida Association of Realtors.268(VII) A representative from the engineering profession269 recommended by the Florida Engineering Society.270b. Members shall be appointed for a term of 3 years, with271 such appointments being staggered so that the terms of no more272 than two members expire in any one year. Members shall serve273 without remuneration, but if requested, shall be reimbursed for274 per diem and travel expenses as provided in s. 112.061.2753.

However, the277 committee shall consider all requirements of law related to278 onsite sewage treatment and disposal systems when making279 recommendations on variance requests for onsite sewage treatment280 and disposal system permits.281(k)(i) A construction permit may not be issued for an282 onsite sewage treatment and disposal system in any area zoned or283 used for industrial or manufacturing purposes, or its284 equivalent, where a publicly owned or investor-owned sewage285 treatment system is available, or where a likelihood exists that286 the system will receive toxic, hazardous, or industrial waste.287 An existing onsite sewage treatment and disposal system may be288 repaired if a publicly owned or investor-owned sewage treatment289 system is not available within 500 feet of the building sewer290 stub-out and if system construction and operation standards can291 be met. This paragraph does not require publicly owned or292 investor-owned sewage treatment systems to accept anything other293 than domestic wastewater.2941. A building located in an area zoned or used for295 industrial or manufacturing purposes, or its equivalent, when296 such building is served by an onsite sewage treatment and297 disposal system, must not be occupied until the owner or tenant298 has obtained written approval from the department. The299 department may not grant approval when the proposed use of the300 system is to dispose of toxic, hazardous, or industrialPage 12 of 33CODING: Words stricken are deletions; words underlined are additions.hb589 -04-erF 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 SENROLLEDCS/CS/CS/HB 589, Engrossed 1 2026 Legislature301 wastewater or toxic or hazardous chemicals.3022. Each person who owns or operates a business or facility303 in an area zoned or used for industrial or manufacturing304 purposes, or its equivalent, or who owns or operates a business305 that has the potential to generate toxic, hazardous, or306 industrial wastewater or toxic or hazardous chemicals, and uses307 an onsite sewage treatment and disposal system that is installed308 on or after July 5, 1989, must obtain an annual system operating309 permit from the department. A person who owns or operates a310 business that uses an onsite sewage treatment and disposal311 system that was installed and approved before July 5, 1989, does312 not need to obtain a system operating permit. However, upon313 change of ownership or tenancy, the new owner or operator must314 notify the department of the change, and the new owner or315 operator must obtain an annual system operating permit,316 regardless of the date that the system was installed or317 approved.3183. The department shall periodically review and evaluate319 the continued use of onsite sewage treatment and disposal320 systems in areas zoned or used for industrial or manufacturing321 purposes, or its equivalent, and may require the collection and322 analyses of samples from within and around such systems. If the323 department finds that toxic or hazardous chemicals or toxic,324 hazardous, or industrial wastewater have been or are being325 disposed of through an onsite sewage treatment and disposalPage 13 of 33CODING: Words stricken are deletions; words underlined are additions.hb589 -04-erF 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 SENROLLEDCS/CS/CS/HB 589, Engrossed 1 2026 Legislature326 system, the department shall initiate enforcement actions327 against the owner or tenant to ensure adequate cleanup,328 treatment, and disposal.329(l)(j) An onsite sewage treatment and disposal system330 designed by a professional engineer registered in the state and331 certified by such engineer as complying with performance332 criteria adopted by the department must be approved by the333 department subject to the following:3341. The performance criteria applicable to engineer-335 designed systems must be limited to those necessary to ensure336 that such systems do not adversely affect the public health or337 significantly degrade the groundwater or surface water. Such338 performance criteria shall include consideration of the quality339 of system effluent, the proposed total sewage flow per acre,340 wastewater treatment capabilities of the natural or replaced341 soil, water quality classification of the potential surface-342 water-receiving body, and the structural and maintenance343 viability of the system for the treatment of domestic344 wastewater. However, performance criteria shall address only the345 performance of a system and not a system's design.3462. A person electing to use an engineer-designed system347 shall, upon completion of the system design, submit such design,348 certified by a registered professional engineer, to the county349 health department. The county health department may use an350 outside consultant to review the engineer-designed system, withPage 14 of 33CODING: Words stricken are deletions; words underlined are additions.hb589 -04-erF 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 SENROLLEDCS/CS/CS/HB 589, Engrossed 1 2026 Legislature351 the actual cost of such review to be borne by the applicant.352 Within 5 working days after receiving an engineer-designed353 system permit application, the county health department shall354 request additional information if the application is not355 complete. Within 15 working days after receiving a complete356 application for an engineer-designed system, the county health357 department shall issue the permit or, if it determines that the358 system does not comply with the performance criteria, shall359 notify the applicant of that determination and refer the360 application to the department for a determination as to whether361 the system should be approved, disapproved, or approved with362 modification. The department engineer's determination shall363 prevail over the action of the county health department. The364 applicant shall be notified in writing of the department's365 determination and of the applicant's rights to pursue a variance366 or seek review under the provisions of chapter 120.3673. The owner of an engineer-designed performance-based368 system must maintain a current maintenance service agreement369 with a maintenance entity permitted by the department. The370 maintenance entity shall inspect each system at least twice each371 year and shall report quarterly to the department on the number372 of systems inspected and serviced. The reports may be submitted373 electronically.3744. The property owner of an owner-occupied, single-family375 residence may be approved and permitted by the department as aPage 15 of 33CODING: Words stricken are deletions; words underlined are additions.hb589 -04-erF 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 SENROLLEDCS/CS/CS/HB 589, Engrossed 1 2026 Legislature376 maintenance entity for his or her own performance-based377 treatment system upon written certification from the system378 manufacturer's approved representative that the property owner379 has received training on the proper installation and service of380 the system. The maintenance service agreement must conspicuously381 disclose that the property owner has the right to maintain his382 or her own system and is exempt from contractor registration383 requirements for performing construction, maintenance, or384 repairs on the system but is subject to all permitting385 requirements.3865. The property owner shall obtain a biennial system387 operating permit from the department for each system. The388 department shall inspect the system at least annually, or on389 such periodic basis as the fee collected permits, and may390 collect system-effluent samples if appropriate to determine391 compliance with the performance criteria.

However, a remodeling addition or658 modification to a single-family home may not cover any part of659 the existing system or encroach upon a required setback or the660 unobstructed area. To determine if a setback or the unobstructed661 area is impacted, the local health department shall review and662 verify a floor plan and site plan of the proposed remodeling663 addition or modification to the home submitted by a remodeler664 which shows the location of the system, including the distance665 of the remodeling addition or modification to the home from the666 onsite sewage treatment and disposal system. The local health667 department may visit the site or otherwise determine the best668 means of verifying the information submitted. A verification of669 the location of a system is not an inspection or evaluation and670 assessment of the system. The review and verification must be671 completed within 7 business days after receipt by the local672 health department of a floor plan and site plan. If the review673 and verification is not completed within such time, the674 remodeling addition or modification to the single-family home,675 for the purposes of this paragraph, is approved.Page 27 of 33CODING: Words stricken are deletions; words underlined are additions.hb589 -04-erF 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 SENROLLEDCS/CS/CS/HB 589, Engrossed 1 2026 Legislature676Section 2.
