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

Yes. Boone County requires a Rural Building Permit for construction in its unincorporated areas, and Planning & Development administers the requirement1. Covered structures on non-farming property also require a zoning permit2. Current construction permit charges run from a $40 minimum to a $1,500 maximum, and Boone County doubles permit fees when construction starts without a valid permit7.

Iowa does not impose one universal building-permit rule on every private building statewide; permit issuance and enforcement depend on the applicable local ordinance13. A person working on their own property is exempt from state contractor registration, but that exemption does not waive Boone County permits or other local requirements14. Boone County's agricultural zoning exemption requires the land and proposed buildings to be farm-related and dwelling occupants to be primarily engaged in agriculture6. The exemption covers zoning only; floodplain, county-tile, well, septic, addressing and driveway approvals may still apply6.

Who issues Boone County building permits, and how do you reach them?

Boone County Planning & Development is the first stop for rural building and zoning questions. The office is at 201 State St., Second Floor, Boone, IA 50036, and its phone number is 515-433-055015. Planning & Development administers the county's subdivision ordinance, zoning ordinance and uniform rural addressing ordinance15. Applications are available through the department's online Applications & Permits page15.

Separate offices handle site-specific approvals. Boone County Health & Sanitation handles septic permitting and inspection at the same courthouse address and can be reached at 515-433-050616. The Engineer/Secondary Roads Department is on the courthouse's first floor at the same street address and can be reached at 515-433-0530 for county-road access questions17. The Boone County Engineer also administers the county floodplain ordinance18. Ask Planning & Development which approvals apply to the parcel before finalizing a building plan.

Does Boone County have zoning?

Yes. Boone County zoning applies in unincorporated territory, while incorporated municipalities may administer their own zoning519. The county has agricultural, residential, commercial, industrial and planned-development districts, so the parcel's mapped district controls20. Lot area, setbacks, building height and lot coverage vary by district and use21222324.

For example, an R-1 residential subdivision generally has 35-foot front and rear setbacks, a 12-foot side setback, 30% maximum lot coverage and a 35-foot maximum building height222423. Those figures are examples, not substitutes for checking the parcel's district and proposed use. Qualifying farm land and farm structures are exempt while used for agriculture5. A land division includes splitting a quarter-quarter section into two or more lots, parcels or divisions for transfer, development or lease, and Planning & Development administers the subdivision ordinance2515.

How do septic and well permits work in Boone County?

Boone County Health & Sanitation handles on-site wastewater permits and inspections, applying Iowa's standards without additional county restrictions263. A new septic system or renovation of an existing system's soil-treatment component requires a county permit27. The current county fee schedule lists a $250 package covering the perc test, permit and final inspection89. Only about 22.8% of county soils are rated without severe limitations for a conventional drain field, so arrange the site evaluation before fixing the house location28.

Where sewer service is unavailable, Boone County requires an approved septic system or other approved treatment process29. For a qualifying residential transfer, Iowa generally requires a certified septic inspection before ownership changes; the inspection remains valid for 2 years, subject to exceptions30. State and county authority overlap: county boards regulate private sewage systems, while the Iowa Department of Natural Resources retains concurrent authority31. Boone County's Sanitation Department issues permits for most private wells, and the listed well-permit fee is $10011.

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

A fixed tiny home used as a single-family dwelling in unincorporated Boone County must be at least 23 feet wide, contain at least 700 square feet and sit on a permanent foundation; it also requires a zoning permit4. District-specific lot size and setbacks still apply2122. Recreational equipment or an RV-type unit used as a dwelling requires a location approved under county zoning, while commercial campgrounds and travel-trailer parks follow separate conditional-use rules10.

A mobile home may serve as a temporary residence during construction under an 18-month zoning permit, with a possible one-year extension from the Board of Supervisors32. Iowa prevents counties from rejecting a compliant home solely because it is manufactured, but allows the permanent-foundation, setback and minimum-area standards applied to a site-built home on the same lot33. Iowa also requires the county to allow at least one accessory dwelling unit where a single-family residence is allowed, subject to building rules and size limits34. Boone County separately limits certain granny flats or mobile homes used as second residences to one per residence for an immediate family member35.

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

  1. Ask Boone County Planning & Development to confirm the parcel's zoning district, allowed residential use, lot-area rules, setbacks, height and lot coverage2021222324.
  2. Submit the rural building and zoning applications before work begins; Boone County doubles permit fees when construction starts without a valid permit136.
  3. If the proposal needs conditional-use approval, allow for public hearings before the Zoning Commission and Board of Adjustment; applications are due 15 working days before the relevant meeting2.
  4. If public sewer is unavailable, obtain the $250 septic package covering the perc test, permit and final inspection89.
  5. Ask Health & Sanitation whether the proposed private well needs the listed $100 well permit11.
  6. Obtain a free entrance permit before installing or extending access on a county-maintained road12.
  7. Contact the County Engineer about floodplain review when the site is in a regulated flood-hazard area18.

What should you check before buying land in Boone County?

Start with zoning: confirm the parcel's district, allowed dwelling type, minimum lot area, setbacks, height and lot coverage with Planning & Development2021222324. If the seller proposes splitting land, county land-division or subdivision review may apply25. For a fixed tiny home, verify that the design clears the 23-foot width, 700-square-foot floor area and permanent-foundation requirements4. For an RV used as a dwelling, confirm an approved location before purchase10.

Evaluate wastewater before choosing the building pad because only about 22.8% of Boone County soils are rated without severe limitations for a conventional drain field28. Confirm well permitting with Health & Sanitation and access with the road authority; a new or extended entrance on a county-maintained road needs a free county permit1112. Check mapped flood hazards with the County Engineer before closing18. A typical county home has an effective property-tax rate near 1.4% and a median annual property-tax bill around $2,7413738.

Watch-outs

  • Starting construction without a valid Boone County permit doubles the applicable permit fee36.
  • A fixed tiny home used as a dwelling must meet Boone County's 23-foot width, 700-square-foot floor-area and permanent-foundation standards4.
  • An RV-type unit used as a dwelling needs a location approved under Boone County zoning10.
  • Boone County's agricultural exemption covers zoning only; septic, well, floodplain, addressing and driveway approvals may still apply6.

Iowa rules that apply here

  • Building permitLimited

    Construction subject to Iowa's State Building Code, including state-owned buildings, buildings in governmental subdivisions that adopt the code, certain cities over 15,000 population without a substantially conforming local code, factory-built structures, and construction covered by statewide energy-conservation provisions.

    • Iowa Code section 103A.10 makes the state building code applicable to all state-owned buildings and structures.
    • The code applies in a governmental subdivision where the governing body has enacted an ordinance accepting the code.
    • The code applies in each city with a population over 15,000 that has not adopted a substantially conforming local building code.
    • Factory-built-structure manufacture and installation provisions apply throughout Iowa.
    • Permit issuance and enforcement are administered under local law or ordinance; the state source does not establish one universal permit requirement for every building statewide.
    • A governmental subdivision may prohibit commencement of construction until a local building department issues a permit after compliance is shown.
    • The application must be signed by the owner or authorized agent and include the owner's address, a statement that the application seeks permission to construct under the code, and a statement that construction will comply with applicable energy-conservation requirements.
    “The examination and approval or disapproval of plans and specifications, the issuance and revocation of building permits, licenses, certificates, and similar documents, the inspection of buildings or structures, and the administration and enforcement of building regulations shall be the responsibility of the governmental subdivisions of the state and shall be administered and enforced in the manner prescribed by local law or ordinance. [...] Prohibit the commencement of construction until a permit has been issued by the local building department after a showing of compliance with the requirements of the applicable provisions of the state building code.”
  • Owner-builder exemptionAvailable (with conditions)

    A person performing work or having work performed on the person's own property, for purposes of Iowa Code chapter 91C contractor registration.

    • The exemption is from being treated as a contractor for purposes of chapter 91C; it is not stated to waive building permits, building-code compliance, inspections, or certificates of occupancy.
    • The separate annual-earnings threshold is less than $2,000, but the own-property exemption is stated independently.
    • A contractor doing business in Iowa must register under chapter 91C unless an applicable statutory exclusion applies.
    “However, a person who earns less than two thousand dollars annually or who performs work or has work performed on the person’s own property is not a contractor for purposes of this chapter.”
  • 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.

    adopted model building code: 2024 International Building Code (Adopted by reference with Iowa amendments.) · current administrative-rule effective date: 2025-09-10 (Iowa Administrative Code Chapter 481.301 source identifies ARC 9474C as effective September 10, 2025.) · local ordinance effective-date limit: <= 6 months after adoption · local withdrawal waiting period: >= 1 year after code became applicable (A governmental subdivision may withdraw only after this period has elapsed.) · withdrawal effective-date minimum: >= 180 days after ordinance adoption (Previously issued permits remain unaffected.)

    “The state building code shall be applicable: [...] In each governmental subdivision where the governing body has enacted an ordinance accepting the application of the code.”
  • InspectionsLimited

    Buildings and structures subject to Iowa Code section 103A.10A, including newly constructed state-owned buildings, state-board-of-regents buildings, and certain state-funded buildings.

    • Newly constructed state-owned buildings and structures subject to the state building code are subject to plan review and inspection, excluding renovations and repairs except as provided by statute.
    • Newly constructed buildings owned by the state board of regents are subject to plan review and inspection, excluding renovations and repairs except as provided by statute.
    • State-funded buildings not wholly owned by the state are subject to state plan review and inspection when the governmental subdivision has not adopted the listed codes or does not perform inspections; otherwise they must comply with the local codes and inspections.
    • For ordinary privately owned construction, inspection administration is governed by the applicable local law or ordinance.
    “All newly constructed buildings or structures subject to the state building code, including any addition, but excluding any renovation or repair of such a building or structure, owned by the state or an agency of the state, except as provided in subsection 2, shall be subject to a plan review and inspection by the commissioner or an independent building inspector appointed by the commissioner.”
  • Certificate of occupancyLimited

    Certificates of occupancy or use for buildings subject to Iowa's State Building Code and certificates approving specified buildings, facilities, or installations for licensure.

    • A local building department issues certificates of occupancy or use when required by ordinance.
    • When issued for a building constructed under the state building code, the certificate must certify conformity with the code and is in the form prescribed by the governing body of the governmental subdivision.
    • For facilities governed by Iowa Administrative Code chapter 481.280, if a certificate of occupancy is required for use, it will not be issued until the inspection fee is paid.
    • Chapter 481.280.5 applies to a certificate approving a building, facility, or installation for occupancy upon request from an owner or owner's agency when applicable rules are satisfied and all fees are paid.
    • The state sources do not require a certificate of occupancy for every building statewide.

    additional reinspection fee: 125 USD (Applies for each additional reinspection after the initial reinspection when original deficiencies remain uncorrected.)

(1) A certificate of occupancy or use for a building or structure constructed in accordance with the provisions of the state building code shall certify that the building or structure conforms to the requirements of the code. The certificate shall be in the form the governing body of the governmental subdivision prescribes.”
  • 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.
