#23 of 99 in Iowa

Unincorporated Jones County, Iowa regulates rural construction through zoning and land-use applications rather than a general residential building-code permit.1 Contact Jones County Land Use before building, buying or dividing rural property, because the required application depends on the parcel, zoning district and proposed use.2 Septic systems, private wells, floodplain work and new or altered access along a county secondary road have separate approval paths.3456

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

For an ordinary home in unincorporated Jones County, the county uses zoning and land-use review rather than a general residential building-code permit.1 That does not mean a parcel is unrestricted: Jones County publishes permitted-use, special-use, variance, rezoning, farm-exemption and subdivision forms, and tells buyers and builders to contact Land Use before work or a land division.2 A permitted-use application carries a $100 published fee under the county schedule.12

Iowa does not impose one universal building-permit rule on every private building; state-code permitting depends on whether the project or governmental subdivision falls within the state code's scope.13 Jones County's general building-code adoption, routine building inspections and certificates of occupancy for ordinary unincorporated construction could not be confirmed, so ask Jones County Land Use what approvals apply to the exact parcel and plans.10

Who handles building and land-use permits in Jones County?

Jones County Land Use is the first call for building, zoning, permitted-use and subdivision questions on rural property.10 The office is in Room 113 of the Jones County Courthouse in Anamosa, and the county asks visitors to call because the Land Use Administrator is part-time.10

Tell the office the parcel number, current zoning district, proposed use, building type and whether the project creates a new lot. Jones County's published process covers farm exemptions, appeals, boundary-line adjustments, rezoning, farmstead splits, permitted uses, special permitted uses, variances and subdivision plats.2 If the tract is being divided into three or more parts and any part is under 40 acres, the county subdivision ordinance applies.14 Projects inside an incorporated city are outside the county zoning ordinance, so contact that city's office instead.7

Does Jones County, Iowa have zoning?

Yes. Jones County zoning applies to land outside the corporate limits of any city, with agricultural and other specific exemptions.7 Districts include agricultural, residential, manufactured-housing, commercial, industrial and planned-development classifications, and allowed uses and dimensions vary by district.9

For a single-family dwelling in the R Residential district, the ordinance lists a 1-acre minimum lot, 150-foot minimum width, 30-foot front and rear setbacks, a 10-foot side setback, and a 35-foot or 2.5-story height limit.151617 Those figures are not universal standards for every parcel. Agricultural land and structures primarily adapted and used for farming may qualify for a zoning exemption, but that exemption does not cover floodplain structures or work.18 Confirm the parcel's current district and any city review area with Jones County Land Use before relying on a map or listing.10

How do septic permits work in Jones County?

Jones County Environmental Health administers private sewage disposal rules for the county.19 Construction, reconstruction or alteration of a private septic system cannot begin until the application is approved; the application, percolation test and fee must be submitted before permit issuance.3 A private septic permit is not issued when the property is within 200 feet of a public sewer, and properties required to connect must follow the sewer operator's conditions.3

Arrange the final inspection before covering the system: Jones County requires 24 hours' advance notice and the system must remain uncovered until inspection is complete.20 A qualifying transfer of property with a private sewage system also requires inspection by a certified inspector, subject to statutory exceptions.21 Only 2.7% of county soils are rated without severe limits for a conventional drain field, so make the perc test and system design an early due-diligence item.22

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

Jones County's zoning definition treats a travel trailer or mobile home within its stated dimensions as a temporary dwelling used for travel or recreation, not permanent habitation.8 The reviewed county material does not establish a complete approval path for temporary camping on private land, so ask Jones County Land Use about duration, utilities and the parcel's zoning before occupying an RV.10

A separate tiny-home occupancy rule and a general minimum dwelling floor area could not be confirmed. Jones County does regulate lot area, setbacks, height and use by zoning district, so a small dwelling still needs parcel-specific review.151617 Iowa protects qualifying manufactured homes from exclusion solely because they are manufactured, but the home remains subject to the same permanent-foundation, setback and minimum-square-footage standards that apply to a site-built home on the same lot.23

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

  1. Call Jones County Land Use before buying, building or dividing rural property, and confirm the zoning district, allowed use, setbacks and required land-use application.102
  1. Ask Environmental Health to review the septic and well path; new or altered private septic systems need county approval, and private-well construction requires a permit.34
  1. Check the flood map and contact Emergency Management before any work in a mapped flood-hazard area, because a Floodplain Development Permit is required before development there.524
  1. Apply through Secondary Roads before constructing a new access or altering an existing access along a Jones County secondary roadway.6
  1. Do not cover the septic system until the county completes its final inspection.20
  1. If doing the work yourself, remember that Iowa's own-property exemption concerns contractor registration and does not waive permits, inspections or code compliance that otherwise apply.11

What should you check before buying land in Jones County?

Start with zoning, legal access, wastewater, water and flood exposure. Jones County Land Use can confirm the rural parcel's current zoning and the application needed for the proposed use.10 A new or altered driveway along a county secondary road requires an access permit, while access to an Iowa primary highway goes through an Iowa DOT district office.625

Treat septic feasibility as a purchase condition because only 2.7% of county soils are rated without severe limits for a conventional drain field.22 Private-well construction requires a permit, and the county application lists a $250 non-refundable fee.4 Check mapped flood hazards before planning any grading, fill, structure or factory-built home, because those activities can require a floodplain permit.5 For cost context, the median annual property-tax bill is $2,381 and the effective property-tax rate is 1.3%, but obtain a parcel-specific estimate from the taxing authorities.2627

Watch-outs

  • A farm-use zoning exemption does not remove floodplain controls from qualifying agricultural structures or work in a river or stream floodplain.18
  • Jones County does not issue a private septic permit within 200 feet of a public sewer.3
  • A travel trailer is defined for temporary use rather than permanent habitation, but a complete private-property camping path could not be confirmed; ask Land Use before moving onto the parcel.810
  • New or altered access along a Jones County secondary road needs an access permit; Iowa DOT handles access to primary highways.625
