However, the ordinances may apply to any structure, building, dam, obstruction, deposit, or excavation in or on the floodplains of any river or stream.2.  A county shall not require an application, an approval, or the payment of a fee in order for an ordinance to be deemed inapplicable to land, farm barns, farm outbuildings, or other buildings or structures that are primarily adapted for use for agricultural purposes under this section.3.  Land, farm houses, farm barns, farm outbuildings, or other buildings or structures may qualify under this section independently or in combination with other agricultural uses. Land enrolled in a soil or water conservation program shall be considered land primarily adapted for use for agricultural purposes under this section.[C50, 54, 58, 62, 66, 71, 73, 75, 77, 79, 81, S81, §358A.2; 1981 Acts, ch 117, §1070; 1982 Acts, ch 1245, §16]C93, §335.22019 Acts, ch 24, §104, 2020 Acts, ch 1034, §1, 5, 6Referred to in 335.3, 368.26, 414.23335.2ASale of consumer fireworks limitation.A county shall not adopt or enforce any ordinance under this chapter to regulate, restrict, or prohibit the location of permanent buildings or temporary structures used for the sale of consumer fireworks pursuant to section 10A.519, in any location zoned for commercial or industrial purposes.2022 Acts, ch 1019, §1, 4

    335.3Powers.1.  Subject to section 335.2, the board of supervisors may by ordinance regulate and restrict the height, number of structures, and size of buildings and other structures, the percentage of lot that may be occupied, the size of yards, courts, and other open spaces, the density of population, and the location and use of buildings, structures, and land for trade, industry, residence, or other purposes, and may regulate, restrict, and prohibit the use for residential purposes of tents, trailers, and portable or potentially portable structures. However, such powers shall be exercised only with reference to land and structures located within the county but lying outside of the corporate limits of any city.2.a.  Except as provided in paragraph “b”, when there is a replacement of a preexisting manufactured, modular, or mobile home with any other manufactured, modular, or mobile home containing no more than the original number of dwelling units, or a replacement of a preexisting site-built dwelling unit with a manufactured, modular, or mobile home or site-built dwelling unit, within a manufactured home community or a mobile home park, the board of supervisors shall not adopt or enforce any ordinance, regulation, or restriction, or impose any conditions on the replacement home, home site upon which the home sits, or the owner’s property that were not required of the preexisting home, home site, or property, that would prevent the continuance of the property owner’s lawful nonconforming use that had existed relating to the preexisting home, home site upon which the home sat, or the owner’s property.b.  Paragraph “a” does not apply if any of the following conditions exist:(1)  The replacement of the preexisting home with the replacement home would substantially increase the risk to the safety of life or property.(2)  The property owner has discontinued and abandoned the nonconforming use for the period of time established by ordinance, unless such discontinuance is caused by circumstances outside the control of the property owner. The period of time so established shall be not less than one year. For purposes of this subparagraph, circumstances outside the control of the property owner include floods, fires, destructive thunderstorm events such as derechos and tornadoes, and similar catastrophic events causing widespread or localized severe property damage. For purposes of this subparagraph, a property owner shall not be considered to have discontinued and abandoned the nonconforming use if the property owner demonstrates that the applicable home site continues to be available for use as a home site for a replacement home.(3)  The replacement results in the overall nature and character of the present use being substantially or entirely different from the original lawful preexisting nonconforming use.(4)  The replacement results in an obstruction to a shared driveway or shared sidewalk providing vehicular or pedestrian access to other homes and uses unless the property owner makes modifications to such shared driveway or sidewalk that extinguishes such obstruction or the effects of such obstruction.[C50, 54, 58, 62, 66, 71, 73, 75, 77, 79, 81, S81, §358A.3; 1981 Acts, ch 117, §1071]C93, §335.32019 Acts, ch 43, §1, 2022 Acts, ch 1070, §17335.4Areas and districts.The board of supervisors may divide the county, or any area or areas within the county, into districts of such number, shape, and area as may be deemed best suited to carry out the purposes of this chapter; and within such districts it may regulate and restrict the erection, construction, reconstruction, alteration, repair, or use of buildings, structures, or land. All such regulations and restrictions shall be uniform for each class or kind of buildings throughout each district, but the regulations in one district may differ from those in other districts.[C50, 54, 58, 62, 66, 71, 73, 75, 77, 79, 81, §358A.4]C93, §335.42020 Acts, ch 1063, §180Referred to in 335.7335.5Regulations and comprehensive plan considerations and objectives notice, adoption, distribution.1.  The regulations shall be made in accordance with a comprehensive plan and designed to preserve the availability of agricultural land; to consider the protection of soil from wind and water erosion; to encourage efficient urban development patterns; to lessen congestion in the street or highway; to secure safety from fire, flood, panic, and other dangers; to protect health and the general welfare; to provide adequate light and air; to prevent the overcrowding of land; to avoid undue concentration of population; to promote the conservation of energy resources; to promote reasonable access to solar energy; and to facilitate the adequate provision of transportation, water, sewerage, schools, parks, and other public requirements. However, provisions of this section relating to the objectives of energy conservation and access to solar energy shall not be construed as voiding any zoning regulation existing on July 1, 1981, or to require zoning in a county that did not have zoning prior to July 1, 1981.2.  The regulations shall be made with reasonable consideration, among other things, as to the character of the area of the district and the peculiar suitability of such area for particular uses, and with a view to conserving the value of buildings and encouraging the most appropriate use of land throughout such county.3.  The regulations and comprehensive plan shall be made with consideration of the smart planning principles under section 18B.1 and may include the information specified in section 18B.2, subsection 2.4.a.  A comprehensive plan recommended for adoption or amendment by the zoning commission established under section 335.8 may be adopted by the board of supervisors.

Notice of the time and place of the hearing shall be published as provided in section 331.305.c.  The board of supervisors may amend a proposed comprehensive plan or amendment prior to adoption. The board of supervisors shall publish notice of the meeting at which the comprehensive plan or amendment will be considered for adoption.

The conditions must be reasonable and imposed to satisfy public needs which are directly caused by the requested change. In case, however, of a protest against the change signed by the owners of twenty percent or more either of the area included in the proposed change, or of the area immediately adjacent to the proposed change and within five hundred feet of the boundaries of the proposed change, the amendment shall not become effective except by the favorable vote of at least sixty percent of all of the members of the board of supervisors.

A county, county board of supervisors, or a county zoning commission shall not require that a family home, its owner, or operator obtain a conditional use permit, special use permit, special exception, or variance. However, new family homes owned or operated by public or private agencies shall be dispersed through the residential zones and districts and shall not be located within contiguous areas equivalent in size to city block areas. Section 135C.23, subsection 2, shall apply to all residents of a family home.4.  A restriction, reservation, condition, exception, or covenant in a subdivision plan, deed, or other instrument of or pertaining to the transfer, sale, lease, or use of property in a county which permits residential use of property but prohibits the use of property as a family home for persons with a developmental disability or brain injury, to the extent of the prohibition, is void as against the public policy of this state and shall not be given legal or equitable effect.83 Acts, ch 11, §1358A.25335.2593 Acts, ch 90, §2, 94 Acts, ch 1023, §107, 94 Acts, ch 1170, §8, 96 Acts, ch 1129, §113, 2012 Acts, ch 1019, §126Referred to in 135C.9, 335.32, 335.33, 504C.1

    335.27Agricultural land preservation ordinance.If a county adopts an agricultural land preservation ordinance under this chapter which subjects farmland to the same use restrictions provided in section 352.6 for agricultural areas, then section 6B.3, subsection 1, paragraph “f”, and sections 352.10 through 352.12 shall apply to farms and farm operations which are subject to the agricultural land preservation ordinance.[1982 Acts, ch 1245, §15,20]C83, §358A.27C93, §335.272021 Acts, ch 80, §219Referred to in 335.2, 352.6335.28Agricultural experiences.1.  For purposes of this section, “agricultural experience” includes any agriculture-related activity, as a secondary use in conjunction with agricultural production, on a farm which activity is open to the public with the intended purpose of promoting or educating the public about agriculture, agricultural practices, agricultural activities, or agricultural products.2.  To assist in the promotion of agricultural experiences, a county shall not require a conditional use permit, special use permit, special exception, or variance for agricultural experiences on property of which the primary use is agricultural production.2020 Acts, ch 1033, §1335.29  Reserved.335.30Manufactured and modular homes.1.  A county shall not adopt or enforce zoning regulations or other ordinances which disallow the plans and specifications of a proposed residential structure solely because the proposed structure is a manufactured home. However, a zoning ordinance or regulation shall require that a manufactured home be located and installed according to the same standards, including but not limited to a permanent foundation system, set-back, and minimum square footage, which would apply to a site-built, single family dwelling on the same lot, and shall require that the home is assessed and taxed as a site-built dwelling. A zoning ordinance or other regulation shall not require a perimeter foundation system for a manufactured home which is incompatible with the structural design of the manufactured home structure. A county shall not require more than one permanent foundation system for a manufactured home. For purposes of this section, a permanent foundation may be a pier footing foundation system designed and constructed to be compatible with the structure and the conditions of the site. When units are located outside a manufactured home community or mobile home park, requirements may be imposed which ensure visual compatibility of the permanent foundation system with surrounding residential structures. As used in this section,“manufactured home” means a factory-built structure, which is manufactured or constructed under the authority of 42 U.S.C. §5403 and is to be used as a place for human habitation, but which is not constructed or equipped with a permanent hitch or other device allowing it to be moved other than for the purpose of moving to a permanent site, and which does not have permanently attached to its body or frame any wheels or axles. This section shall not be construed as abrogating a recorded restrictive covenant.2.  A county shall not adopt or enforce construction, building, or design ordinances, regulations, requirements, or restrictions which would mandate width standards greater than twenty-four feet, roof pitch, or other design standards for manufactured housing if the housing otherwise complies with 42 U.S.C. §5403. A county shall not adopt or enforce zoning or subdivision regulations or other ordinances which mandate width standards for a single modular or manufactured home which is sited upon land otherwise zoned as agricultural land. However, this subsection shall not prohibit a county from adopting and enforcing zoning regulations related to transportation, water, sewerage, or other land development.3.  A county shall not require an inspection of a manufactured home that has been inspected according to requirements of the United States department of housing and urban development and constructed in conformance with the federal manufactured home construction and safety standards provided in 24 C.F.R. pt.3280.84 Acts, ch 1238, §1358A.30335.3093 Acts, ch 154, §3, 94 Acts, ch 1110, §1, 97 Acts, ch 86, §1, 2001 Acts, ch 153, §16, 2020 Acts, ch 1062, §46, 2021 Acts, ch 80, §220, 2022 Acts, ch 1134, §1335.30ALand-leased communities.1.  A county shall not adopt or enforce zoning or subdivision regulations or other ordinances which disallow or make infeasible the plans and specifications of land-leased communities because the housing within the land-leased community will be manufactured housing.2.  “Land-leased community” means any site, lot, field, or tract of land under common ownership upon which ten or more occupied manufactured homes are harbored, either free of charge or for revenue purposes, and shall include any building, structure, or enclosure used or intended for use as part of the equipment of the land-leased community. The term “land-leased community” shall not be construed to include homes, buildings, or other structures temporarily maintained by any individual, educational institution, or company on their own premises and used exclusively to house their own labor or students. A manufactured home located in a land-leased community shall be taxed under section 435.22 as if the manufactured home were located in a mobile home park.97 Acts, ch 86, §2, 98 Acts, ch 1107, §10, 33, 2020 Acts, ch 1062, §94Referred to in 331.301, 364.3, 435.1, 441.21, 562B.7335.31Elder family homes.Repealed by 2004 Acts, ch 1101, §95. 335.32Homes for persons with disabilities.A county board of supervisors or county zoning commission shall consider a home for persons with disabilities a family home, as defined in section 335.25, for the purposes of zoning, in accordance with chapter 504C.93 Acts, ch 90, §3, 94 Acts, ch 1023, §108, 2010 Acts, ch 1079, §14

A county, county board of supervisors, or county zoning commission shall not establish limitations regarding the proximity of one such residence to another.3.  A county, county board of supervisors, or a county zoning commission shall not classify such a residence as a residential group R-3 occupancy or as a care facility within a dwelling for the purposes of enforcement of compliance with the sprinkler systems provisions specified in section 903.3.1.3 of the international building code or section P2904 of the international residential code, if adopted, or if such residence is inspected by the county.4.  This section applies to the residence of a recipient of services under a home and community-based services waiver if the residence meets any of the following conditions:a.  The residence is a single-family dwelling owned or rented by the recipient.b.  The residence is a multifamily dwelling which does not hold itself out to the public as a community-based residential provider otherwise regulated by law, including but not limited to a residential care facility, and which provides dwelling units to no more than four recipients of services under a home and community-based services waiver at any one time.5.  For the purposes of this section, “home and community-based services waiver” means “waiver” as defined in section 249A.29.2007 Acts, ch 218, §130, 132, 2023 Acts, ch 112, §64, 66
