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

Unincorporated Montgomery County requires a zoning permit or certificate for specified non-farm projects, including new principal buildings, accessory buildings of at least 120 square feet, building extensions, mobile or manufactured housing, changes in use or occupancy, and land disturbance from 1 through 5 acres.1 Agricultural uses are exempt from that county zoning permit and certificate requirement, although other health, septic, floodplain, road or state requirements can still apply.2

The county material establishes a zoning approval system; it does not confirm a general county building-code permit for every ordinary private home.1 Iowa’s state building code applies only in specified situations, including state construction, qualifying state-funded work, factory-built structures and governmental subdivisions that adopt it.9 Ask the Montgomery County Zoning Administrator which certificate applies to the parcel and project before ordering materials.10

Who issues permits in Montgomery County, and how do you reach them?

The Montgomery County Zoning Administrator is the first stop for zoning certificates, rezoning and subdivision forms; the county’s zoning page publishes a zoning-certificate form and subdivision applications.10 The office is at the Montgomery County Engineer, 406 W. 4th St, Red Oak, IA 51566, and the listed phone is 712-623-5197.10

The Montgomery County Sanitarian issues septic-system construction permits and tests non-public water wells.11 The Sanitarian works through Montgomery County Public Health at 1109 Highland Ave, Red Oak, IA 51566, with phone 712-357-1239.11 For a new county-road entrance or right-of-way work, contact Montgomery County Engineer & Secondary Roads, whose page publishes entrance and right-of-way permit forms.12 No general certificate-of-occupancy requirement for ordinary buildings was confirmed; ask the Zoning Administrator what final approval applies to the proposed use.13

Does Montgomery County, Iowa have zoning?

Yes. Montgomery County zoning applies in the unincorporated county, while incorporated cities may have their own rules.4 The ordinance includes agricultural, residential, commercial, industrial, unclassified and mobile-home-park provisions, with requirements that vary by district.14 Lot area and width depend on the zoning district and can also be affected by lot-of-record exceptions.15

Setbacks are likewise district-specific; for lots of record, the stated floors are 25 feet at the front, 5 feet at a noncommercial or nonindustrial side, and 10 feet at the rear.16 A county-defined dwelling must contain at least 800 square feet, measure at least 20 feet wide, sit on an approved permanent foundation and be taxed as real property.6 Before treating a listing as buildable, ask the Zoning Administrator for the parcel’s district, applicable dimensional table and any special-use review.10

How do septic permits work in Montgomery County?

A construction permit from the administrative authority is required before installing or altering a private sewage-disposal system, except for a repair that does not change treatment or disposal.5 In Montgomery County, the County Sanitarian issues septic construction permits.3 Where public treatment is unavailable, a building in which people reside, gather or work must have an approved private sewage-disposal system.17

Site conditions deserve early attention: none of the county’s mapped soils are rated without severe limitations for a conventional septic drain field.18 That soil rating does not itself deny a permit, but it makes an early site evaluation especially valuable.18 When a publicly owned treatment works becomes available within 200 feet, a building served by private septic must connect on the schedule or conditions set by the administrative authority.19 A qualifying property transfer also requires a septic inspection before ownership changes, subject to listed exceptions and alternative procedures.20

Can you live in an RV or tiny home in Montgomery County?

Montgomery County’s complete rule for long-term RV occupancy or temporary camping on private land could not be confirmed, so ask the Zoning Administrator about the parcel, duration, utilities and whether a special use is required.10 A manufactured home, mobile home or unique housing may be allowed as a special permitted use when it meets the setbacks for a principal permitted structure.21

A tiny home intended as a county-defined dwelling faces the county’s minimum of 800 square feet, minimum width of 20 feet, approved permanent foundation and real-property taxation requirements.6 Because the ordinance does not provide a complete tiny-home occupancy answer, confirm the proposed structure’s classification with the Zoning Administrator before purchase.10 Iowa also prevents a county from rejecting a residential structure solely because it is a manufactured home, but the home remains subject to standards that apply to a site-built single-family dwelling on the same lot.22

Building a home in Montgomery County: what are the steps?

  1. Ask the Montgomery County Zoning Administrator to identify the parcel’s zoning district, allowed use, lot standards, setbacks and required certificate.4
  1. Prepare the written application on the approved form with plans in duplicate and drawn to scale.23
  1. Obtain applicable state approvals and county Sanitarian well and septic permits, including an approved sewage-system plan where sanitary facilities are required.8
  1. Contact Montgomery County Engineer & Secondary Roads about a new county-road entrance; the department publishes an entrance-permit form.12
  1. Stake the lot and building location before construction begins.23
  1. Start work within 6 months and complete the proposed construction or alteration within 18 months to avoid the ordinance’s timing problem.23

An owner working on the owner’s own property is outside Iowa contractor registration for this purpose, but that exemption does not waive zoning, permits, codes or inspections that otherwise apply.7

What should you check before buying land in Montgomery County?

Confirm the zoning district, allowed use, lot area, width and setbacks with the Montgomery County Zoning Administrator before relying on an advertised building site.15 If the property will be divided, the county zoning page publishes minor- and major-subdivision applications.24 Ask the Sanitarian to evaluate septic and well needs early because none of the mapped soils are rated without severe limitations for a conventional septic drain field.18

Check flood exposure as well: the county’s unclassified flood-prone district limits development and uses special construction standards.25 Verify legal and physical access with Montgomery County Engineer & Secondary Roads when the parcel fronts a county road.12 For budgeting context, the county’s effective property-tax rate is about 1.8%, and the median annual property-tax bill is about $1,968.2627 Those countywide figures are context, not a parcel estimate; obtain the parcel assessment and tax record before closing.2627

Watch-outs

  • A zoning certificate is not proof that Montgomery County requires or performs general building-code review for every private home; ask the Zoning Administrator what approvals apply.1
  • Long-term RV living and temporary camping rules could not be confirmed; ask the Zoning Administrator before using an RV as housing.10
  • A qualifying ownership transfer of a building served by private septic generally requires an inspection before transfer.20
  • Development in the county’s flood-prone unclassified district is subject to special limits and construction standards.25

    • 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.”
  • 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.)

    “Issue certificates of occupancy or use, permits, licenses, and other documents in connection with the construction of buildings or structures as may be required by ordinance. (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.”
  • Septic permitRequired

    Installation or alteration of private sewage disposal systems in Iowa, including Montgomery County.

    • The permit is issued by the administrative authority.
    • Systems must comply with Iowa Administrative Code chapter 69.
    • Repair of existing components that does not change treatment or disposal is exempt from the construction/alteration rule.
    “No private sewage disposal system shall be installed or altered as described in paragraph 69.1(3)“c” unless a construction permit issued by the administrative authority has been obtained.”
  • Septic inspectionRequired

    Private sewage disposal systems serving buildings with one through four dwelling units, before qualifying ownership transfers statewide.

    • Exceptions include specified court-ordered, foreclosure-related, fiduciary, family, demolition, recently installed system, partition, tax-sale, low-consideration, and qualifying family-entity transfers.
    • The septic tank must be opened and pumped at inspection, unless evidence shows it was properly pumped within three years before inspection by a licensed commercial septic tank cleaner.
    • A failing system must be renovated; a properly treating system without an unsanitary condition need not meet current construction standards.

    • An inspection is valid for two years for ownership transfers during that period.

    dwelling units: 1-4 · inspection validity: 2 years (for ownership transfers during that period) · prior septic pumping evidence: <= 3 years (must be by a department-licensed commercial septic tank cleaner) · civil penalty for fraudulent report: 5000 USD (and certification suspension for one year)
