#55 of 99 in Iowa

Unincorporated Ida County, Iowa requires a permit before excavation for, or the erection or alteration of, a building under the county's zoning ordinance, though agricultural uses are exempt1. Confusingly, the county runs a second, unrelated permit too: a no-fee dwelling or outbuilding permit from the Assessor's Office, used only to gather statistical data for property assessment2. Ida County does zone the unincorporated area, with districts for residential, agricultural, mobile-home-park and commercial uses3. Septic systems are separate again, permitted through the county's Environmental Health Sanitarian, which contracts with state agencies for septic and well permitting4.

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

Yes, in a limited but real sense. Under the zoning ordinance for the unincorporated area, a permit is required before excavation for, or the erection or alteration of, any building, with agricultural uses exempted under the ordinance's Section 22113. Before that permit issues, the ordinance requires an approved Certificate of Zoning Compliance, plus plans and evidence of adequate water supply and sewage disposal for any use13. Separately, and confusingly, the county's Assessor's Office runs its own no-fee permit for houses and outbuildings built in the rural, unincorporated area — printed at home or picked up at the courthouse, then returned to the Assessor's Office — described as strictly for gathering statistical data for county assessment and not for restricting or regulating farming operations2. Iowa's statewide building code (Chapter 103A) only applies in Ida County if the county's governing body has formally adopted it by ordinance and filed a certified copy with the state commissioner, and no official source located for this guide confirms whether Ida County has done so1415.

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

For the zoning-ordinance building permit and Certificate of Zoning Compliance, the ordinance directs applicants to the Zoning Administrator, who also decides zoning-compliance questions that can be appealed to the county's Board of Adjustment16. For the separate no-fee statistical permit covering houses and outbuildings in the rural, unincorporated area, contact the Ida County Assessor's Office at the Ida County Courthouse, 712-364-3622: print the permit form or pick one up at the courthouse, and return the completed permit to that same office2. For a driveway or other permit to use a county secondary road, contact the Ida County Engineer at 401 Moorehead Street, Ida Grove, IA 51445, 712.364.2920, [email protected]17. For septic and well questions, contact the Ida County Environmental Health Sanitarian at the same courthouse address, 712.364.2533, [email protected]18.

Does Ida County have zoning?

Yes. Ida County's zoning ordinance governs the unincorporated area of the county, dividing it into districts including RS (residential), AG (agricultural), RMH (mobile home park), and commercial and industrial districts35. In the RS district, a one-family home needs a lot of at least 10,000 square feet and 80 feet of width, a two-family home needs 12,000 square feet and 90 feet of width, and setbacks run 35 feet front and rear with side yards totaling 20 to 25 feet, all subject to modifications in Section 18 of the ordinance819. Principal buildings in that district are capped at 35 feet and three stories, accessory buildings at 12 feet and one story20. Mobile and manufactured homes have narrower rules: the ordinance allows only one mobile home as living quarters in the AG district, and only for the owner, an owner's employee, or specific family members, while separate mobile-home-park development falls under the RMH district with a 5-acre minimum and 50-foot yards910. Iowa law exempts farmhouses, farm barns, farm outbuildings and other structures primarily adapted for agricultural use from county zoning ordinances while so used21. Incorporated cities inside the county set their own separate zoning; the county's ordinance covers unincorporated land only5.

How do septic and well permits work in Ida County?

Septic systems in Ida County are permitted through the county's Environmental Health Sanitarian, who serves under the county Board of Health and contracts with state agencies for septic-system and well-construction permitting4618. Statewide, county boards of health must enforce standards at least as strict as the state's, while the Iowa DNR retains concurrent authority22. Soils are a real factor here: only 18.7% of Ida County's land is free of severe limitations for a conventional septic drain field, so budget for a site evaluation and the possibility of an engineered or alternative system12. If you ever sell, Iowa requires a private sewage disposal system serving one to four dwelling units to be inspected before transfer of ownership, with that inspection valid for two years23. A new water well also needs a permit before drilling, and Iowa first requires registering every well on the property, including abandoned ones24.

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

No official Ida County source located for this guide addresses RV, travel-trailer, or tiny-home occupancy on ordinary rural land outside a designated park, so treat it as an open question rather than an assumed yes or no3. The zoning ordinance does regulate recreational-vehicle parks as a specific commercial use, with minimum lot size, yard setbacks, and site-plan review by the Zoning Administrator, but that provision governs commercial RV parks, not occupancy on an ordinary private lot16. The ordinance's clearest private-land mobile-home rule limits occupancy to the AG district, and only for the owner, an owner's employee, or specific family members living in a single mobile home9. Statewide, Iowa also bars a county from rejecting a manufactured home's plans solely because it's manufactured, but requires it to meet the same foundation, setback, and minimum-square-footage standards that apply to a site-built home on the same lot25. Ask the Zoning Administrator directly before assuming RV or tiny-home living is allowed on a specific parcel16.

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

First, confirm your parcel's zoning district, and whether the AG-district mobile-home exception or the RS-district dimensional standards apply to your plan58. Second, apply to the Zoning Administrator for a Certificate of Zoning Compliance before applying for the building permit; the ordinance also requires plans and proof of adequate water supply and sewage disposal at this stage1316. Third, get a septic site evaluation and permit from the Environmental Health Sanitarian before you build, since only 18.7% of county soils are free of severe septic limitations1812. Fourth, if you need a new well, register any existing wells on the property and get a well-construction permit before drilling24. Fifth, pick up or print the Assessor's Office no-fee permit for your house or outbuilding and return it to that office2. Sixth, if your driveway connects to a county road, get a roadway-use permit from the County Engineer; if it connects to a state highway, apply through the Iowa DOT district office instead1726. Seventh, if your land is in a mapped flood-prone area, check whether you need an Iowa DNR floodplain permit through the state's PERMT screening tool, which typically carries no fee2728. Finally, apply for your occupancy certificate from the Zoning Administrator once construction is complete; it should issue within seven days for a $30 fee, and no building may be occupied until it's issued7.

What to check before you buy land in Ida County

Water and soils deserve real budget here: annual precipitation runs about 31.7 inches, 16% of years bring severe drought, and only 18.7% of the county's soils are free of severe septic limitations293012. The land itself is gentle and mostly cleared for farming — 95.1% sits at 15% slope or less, and only 1.1% is wooded — good for building sites but with little natural buffer or shade3132. Confirm which zoning district your parcel sits in, and whether it's inside or outside an incorporated city, since the county's zoning ordinance and permit process apply only in unincorporated Ida County5. If the tract has a mobile home on it, or you're planning to add one, ask the Zoning Administrator whether it complies with the AG-district family-use limits or the separate RMH mobile-home-park rules before you close910. Typical property tax runs about 1.1% effectively, with a median bill near $1,158 a year, against a typical home value around $159,185333435.

Watch-outs

  • No official Ida County source confirms whether the county has adopted Iowa's statewide building code by ordinance, so ask the Zoning Administrator or Assessor's Office directly about current inspection requirements15.
  • Ida County runs two separate permit processes for a new home: a zoning-ordinance Certificate of Zoning Compliance and building permit from the Zoning Administrator, and an unrelated no-fee statistical permit from the Assessor's Office — plan on both162.
  • RV, tiny-home, and short-term-rental occupancy on private rural land are not addressed by any official Ida County source found for this guide; confirm directly with the Zoning Administrator before assuming a use is allowed16.
