#64 of 99 in Iowa

Unincorporated Fremont County, Iowa requires a county zoning certificate before excavating, building, enlarging, altering or moving a structure; the county form is often described as a building-permit application, but it does not establish a separate county building-code permit1. Fremont County also administers zoning outside city limits, while the Fremont County Board of Health has local authority over private septic systems and water supplies2,3.

Do you need a building permit in Fremont County, Iowa?

Yes, for work covered by county zoning.

Yes, for work covered by county zoning. Before excavating, erecting, constructing, reconstructing, enlarging, altering or moving a structure in unincorporated Fremont County, apply to the Zoning Administrator for the county zoning certificate commonly described as a building permit1. The form asks for the proposed work, uses, estimated cost, construction dates, legal description, signatures, drawings and a fee1. The published non-refundable schedule starts at $10 for building value through $1,000, then adds $0.50 per $1,000 or fraction through $50,000 and $0.25 per $1,000 or fraction above $50,0001. The form is grounded in county zoning law and does not prove that Fremont County separately adopted and enforces a county building code; statewide energy-efficiency rules and factory-built-structure provisions still apply where relevant9.

Who handles Fremont County building permits, and how do you reach them?

The Fremont County Zoning Administrator works through the County Engineer's Office and handles the county zoning certificate; call (712) 374-2613.

The Fremont County Zoning Administrator works through the County Engineer's Office and handles the county zoning certificate; call (712) 374-26132. Mills County Environmental Health is the published service contact for private sewage disposal questions in Fremont County; call 712-527-9699 option 410. Local legal authority over private septic systems and private water supplies rests with the Fremont County Board of Health, with concurrent Iowa Department of Natural Resources authority3. For a driveway affecting a county secondary road or right-of-way, contact the Fremont County Secondary Road Department at 712-374-26138,11. The only confirmed county building-inspection rule concerns re-entry after a mandatory evacuation when Emergency Management determines an inspection is necessary; it is not a general construction-inspection program7. Ask the Zoning Administrator whether an ordinary project needs inspections or an occupancy document2.

Does Fremont County have zoning?

Yes.

Yes. Fremont County administers zoning on land outside the corporate limits of its cities through a Zoning Commission, Board of Adjustment, Zoning Administrator and enforcement administrator2. Iowa law generally exempts qualifying agricultural land and structures primarily adapted to agricultural use, but floodplain rules can still apply12. Current county district standards for setbacks, minimum lot area, minimum dwelling size, lot coverage and building height could not be confirmed, so ask the Zoning Administrator to identify the parcel's district and applicable dimensions before design work2. Fremont County also publishes fees for preliminary and final subdivision plats, while Iowa generally requires a subdivision plat when repeated or simultaneous division creates 3 or more qualifying parcels1,13. In regulated floodplain areas, residential subdivision lots need vehicle access passable during the base flood, and larger proposals must provide base-flood-elevation data6.

How do septic permits work in Fremont County?

A construction permit is required before installing or altering a private sewage disposal system in Fremont County, with a limited exception for repairs that do not change treatment or disposal.

A construction permit is required before installing or altering a private sewage disposal system in Fremont County, with a limited exception for repairs that do not change treatment or disposal14. The Fremont County Board of Health carries local authority, and Mills County Environmental Health is the county's published service contact3,10. New or altered systems require a final inspection before backfilling15. A private system serving a building with 1 through 4 dwelling units generally must also be inspected by a certified inspector before a qualifying ownership transfer; statutory exceptions apply, and an inspection is valid for 2 years16. Only about 21.9% of Fremont County soils are rated without severe limits for a conventional drain field, so complete septic feasibility work before fixing the house location17.

Can you live in an RV or tiny home on land in Fremont County?

Fremont County's general rules for living in an RV or occupying a tiny home could not be confirmed, so ask the Zoning Administrator about the parcel's district, duration of use, utilities and dwelling type.

Fremont County's general rules for living in an RV or occupying a tiny home could not be confirmed, so ask the Zoning Administrator about the parcel's district, duration of use, utilities and dwelling type2. In a special flood hazard area, an RV must stay for less than 180 consecutive days and remain licensed and ready for highway use, or meet the anchoring and elevation rules for factory-built homes6. A manufactured home cannot be rejected solely because it is manufactured, though the same foundation, setback and minimum-square-footage standards applied to a site-built single-family home on the lot may apply12. Iowa counties must allow at least 1 accessory dwelling unit on a single-family lot in a district allowing a single-family residence, subject to the statewide size and building conditions effective July 1, 202618.

Building a home in Fremont County: the steps, in order

Call the Fremont County Zoning Administrator at (712) 374-2613 to confirm the parcel's district, allowed use and zoning-certificate requirements.

  1. Call the Fremont County Zoning Administrator at (712) 374-2613 to confirm the parcel's district, allowed use and zoning-certificate requirements1,2.
  1. Submit the zoning application with the property description, proposed use, project cost, construction dates, signatures, drawings and non-refundable fee1.
  1. Contact Mills County Environmental Health about septic approval, and obtain the required construction permit before installing or altering a private system10,14.
  1. Obtain a private well construction permit before drilling a water-supply well; a certified well contractor must perform the work5.
  1. Secure a floodplain development permit before covered work in a regulated floodplain, and apply through the Engineer's Office before creating a driveway affecting a county secondary road6,8.
  1. Ask the Zoning Administrator whether the project needs routine inspections or an occupancy document because neither general requirement could be confirmed2.

What should you check before buying land in Fremont County?

Confirm the parcel's zoning district, allowed use and dimensional standards with the Fremont County Zoning Administrator before closing.

Confirm the parcel's zoning district, allowed use and dimensional standards with the Fremont County Zoning Administrator before closing2. If the seller is transferring a building served by a private septic system, determine early whether the time-of-transfer inspection applies and who will handle any required repairs16. Order septic feasibility work because only about 21.9% of county soils are rated without severe limitations for a conventional drain field17. Check mapped flood hazards because regulated floodplain development needs a county permit, and floodplain subdivision proposals carry additional access and elevation-data rules6. Verify access and obtain an Engineer's Office permit for a driveway affecting a county secondary road8. For carrying costs, Fremont County's effective property-tax rate is about 1.3%, its median property-tax bill is about $1,918 per year, and a typical home-insurance premium is about $1,825 per year17.

Watch-outs

  • A Fremont County zoning certificate does not replace a septic construction permit, private well construction permit, floodplain development permit or county-road driveway permit when those approvals apply1,5,6,8,14.
  • Fremont County's general RV and tiny-home occupancy rules could not be confirmed; the Zoning Administrator should review the exact parcel and proposal before purchase or placement2.
  • Do not assume the county zoning certificate means Fremont County performs ordinary building-code inspections; the confirmed county inspection rule is limited to re-entry after a mandatory evacuation when Emergency Management requires inspection7,9.

  • Building code adoptedPartial

    The Iowa State Building Code, including the 2024 International Building Code adopted by reference with Iowa amendments, applies statewide to state-owned buildings and structures, qualifying state-funded construction, certain cities over 15,000 that lack a substantially equivalent local building code, and governmental subdivisions that accept the code by ordinance. Factory-built-structure provisions apply throughout Iowa.

    • In a governmental subdivision, the code generally applies only after the governing body enacts an ordinance accepting applicability and files a certified copy with the commissioner.
    • The local ordinance fixes the effective date, which must be no more than six months after adoption.
    • A governmental subdivision may withdraw after one year by ordinance, following the required public hearing and written notice; the withdrawal date must be at least 180 days after ordinance adoption, and previously issued permits are unaffected.
    • The state building code applies to state-owned buildings and structures and to newly constructed buildings and structures paid for in whole or in part with state-appropriated money but not wholly state-owned.
    • Cities with populations over 15,000 that lack a local building code substantially in accord with nationally recognized standards must enforce the state building code.
    • Factory-built-structure provisions apply throughout the state; an approved factory-built structure is deemed compliant with building regulations applicable to its manufacture and installation and is exempt from other state or local building regulations, subject to the statutory exceptions concerning professional engineering and architecture and manufactured homes.
    • The current administrative rule adopts the 2024 International Building Code by reference with amendments; detached one- and two-family dwellings, certain townhouses not more than three stories, and their accessory structures instead comply with the amended International Residential Code.

    • At inspection, an existing septic tank must be opened and pumped as provided by rule, unless the owner provides evidence it was properly pumped within the prior three years by a department-licensed commercial septic tank cleaner, including documentation of tank size and condition.
    • A failing or improperly functioning system must be renovated to current department construction standards by the seller or, by agreement and within a reasonable time determined by the county board of health or department, by the buyer.
    • The system need not meet current construction standards if it is properly treating wastewater and is not creating an unsanitary environmental condition at inspection.
    • Exceptions include court-ordered transfers; specified mortgagee or foreclosure-related transfers; fiduciary transfers; transfers between joint tenants or tenants in common; transfers to a spouse or lineal descendant; specified transfers between spouses; transfers where the transferee intends to demolish or raze the building; systems installed not more than two years before transfer; partition deeds; tax sale deeds; transfers for consideration of $500 or less; and specified family-entity deeds.

  • Off-grid sanitationLimited

    On-site sanitation where no POTW is available.

    • An approved private sewage disposal system is required when a POTW is unavailable.
    • Discharge to ditches, streams, ponds, lakes, waterways, drain tiles, groundwater, or the ground surface is prohibited.

    • A private well construction permit is required for all water-supply wells.
    • For private water-supply wells serving fewer than 25 individuals or fewer than 15 water-service connections, permits are issued by local county health departments, except Osceola County, which lacks authority to issue private well construction permits; the Iowa DNR handles permitting there.

  • Agricultural exemptionConditional

    Land, farm houses, farm barns, farm outbuildings, and other buildings or structures primarily adapted by reason of nature and area for agricultural purposes, while used for those purposes, under county ordinances adopted pursuant to Iowa Code chapter 335.

    • The exemption applies except to the extent required to implement section 335.27.
    • An ordinance may still apply to any structure, building, dam, obstruction, deposit, or excavation in or on the floodplains of any river or stream.
    • The county may not require an application, approval, or fee for the ordinance to be deemed inapplicable under this section.
    • Qualifying land, farm houses, farm barns, farm outbuildings, or other buildings or structures may qualify independently or in combination with other agricultural uses.
    • Land enrolled in a soil or water conservation program is considered land primarily adapted for agricultural purposes.
    • The exemption concerns ordinances adopted under chapter 335; chapter 335 applies to a county at the option of its board of supervisors.
    “no ordinance adopted under this chapter applies”
  • Shed and accessory-building permit exemptionConditional

    Planning and design services for outbuildings connected with detached residential buildings in Iowa; this is an exemption from Iowa's architect-licensure requirement, not an affirmative exemption from any locally administered building permit or land-use requirement.

    • The detached residential building may contain no more than 12 family dwelling units.
    • The detached residential building may be no more than three stories.
    • The outbuilding must be in connection with the detached residential building.
    • Iowa's current residential construction rule adopts the 2024 International Residential Code for covered dwellings and accessory structures, but deletes sections R103 through R114 and their subsections; the cited state rule therefore does not itself preserve the model-code permit administration provisions.
    • Local building, zoning, septic, well, electrical, plumbing, and other applicable requirements are not displaced by this architect-licensure exception.

    maximum family dwelling units in detached residential building: <= 12 family dwelling units · maximum stories in detached residential building: <= 3 stories

    “Detached residential buildings containing twelve or fewer family dwelling units of not more than three stories and outbuildings in connection with the buildings.”

  • county zoning authorityGeneral

    Iowa counties may adopt zoning ordinances for land and structures within the county but outside the corporate limits of any city.

    • Chapter 335 applies to any Iowa county at the option of its board of supervisors.
    • The zoning power is subject to Iowa Code section 335.2: ordinances generally do not apply to agricultural land, farm houses, farm barns, farm outbuildings, or other structures primarily adapted for agricultural purposes while so used, except that ordinances may apply to structures, buildings, dams, obstructions, deposits, or excavations in or on river or stream floodplains.
    • A county may not require an application, approval, or fee for an ordinance to be deemed inapplicable to qualifying agricultural land or structures.
    • A county may not regulate, restrict, or prohibit the location of permanent buildings or temporary structures used for consumer-fireworks sales pursuant to section 10A.519 in locations zoned commercial or industrial.
    • The board of supervisors may divide the county into zoning districts, and regulations may differ among districts.
    • Regulations and restrictions require public-hearing and notice procedures under sections 335.6 and 331.305; district boundaries must identify the affected township and section and, if possible, streets or roads.
    • Energy-conservation and solar-access objectives do not require zoning in a county that did not have zoning before July 1, 1981.
    “applicable to any county [...] at the option of the board of supervisors [...] outside of the corporate limits of any city.”
  • county building authorityGeneral

    Iowa counties may adopt, administer, and enforce county building codes and may administer and enforce the state building code for buildings, including residential construction, in county jurisdiction outside incorporated municipalities, subject to statutory limitations.

    • A county building code may not apply within the incorporated area of a city except at the city's option.
    • A county building code may not apply within a city's two-mile limit under Iowa Code §414.23 to the extent the city has adopted a building code within that two-mile limit.

    • Administration and enforcement are conducted as prescribed by local law or ordinance.
    • The state building code applies in a governmental subdivision only after the governing body adopts an ordinance accepting it and files a certified copy with the commissioner; the ordinance fixes the effective date, which must be no more than six months after adoption.
    • A local building department may prohibit commencement of construction until a permit is issued after showing compliance with applicable state building-code provisions.
    • Thermal-efficiency energy-conservation standards apply to construction containing heated or cooled enclosed space, but the commissioner must provide appropriate exceptions where applying an energy-conservation requirement would be impractical.
    “The power to adopt, administer, and enforce the state building code shall be exercised in accordance with chapter 103A. The power to adopt by ordinance, administer, and enforce a county building code, is subject to the following restrictions: a. A county building code shall not apply within the incorporated area of a city except at the option of the city, and shall not apply within a city’s two-mile limit referred to in section 414.23, to the extent that the city has adopted a building code within the two-mile limit. b. A county building code shall not apply to farm houses or other farm buildings which are primarily adapted for use for agricultural purposes, while so used or under construction for that use.”
