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

Yes. Before erecting, constructing, moving in or structurally altering a building or structure in unincorporated Floyd County, obtain the required zoning certificate and do not begin improvements until the required permit is issued.110 The certificate becomes void after twelve months unless the covered construction, moving, remodeling, reconstruction or use begins within that period.11

A qualifying agricultural building in the Agriculture District can avoid the zoning-certificate requirement only after an Agricultural Building Permit Exemption Application is approved.1 Floyd County requires the agricultural-use claimant to file its exemption application, and the exemption does not cover floodplain controls or county health rules for septic systems and wells.12 Iowa lets counties adopt their own building code or accept the state building code, but the state code applies in a county only after its governing body adopts an ordinance accepting it.1314 Floyd County's general construction code, ordinary building-inspection schedule and separate certificate-of-occupancy requirement could not be confirmed, so ask Planning & Zoning what applies to the proposed structure.15

The county ordinance asks the agricultural-use claimant to file an exemption application, yet Iowa law says a county may not require an application, approval or fee for the agricultural exemption to apply.1216 Because the two statements conflict, ask Planning & Zoning how it handles a farm building before you build.15

Who issues building permits in Floyd County, Iowa?

Floyd County Planning & Zoning reviews building-permit applications and site plans and issues building permits or zoning certificates for new structures.15 The office is at 101 S Main Street, Suite 206, Charles City, IA 50616, and its phone number is 641-257-6145.15

Consult the Zoning Administrator before filing a subdivision, rezoning, conditional-use or variance request; complete documentation is required, and the land-use decision may have to come before the building permit.2 Floyd County regulates subdivision plats and land divisions.17 An application requiring board action carries a published $300 fee and should be submitted at least 21 working days before the relevant meeting.18 Floyd County has not published a general building-permit fee in the materials available here, so ask Planning & Zoning for the current project total.19

Does Floyd County, Iowa have zoning?

Yes. Floyd County zoning applies in unincorporated areas and divides that territory among ten districts; incorporated-city rules are separate.520 Each district has its own permitted and conditional uses, and a conditional use may require a public hearing before the Board of Adjustment.21

Setbacks and minimum lot sizes depend on the parcel's district.2223 For example, an R-1 single-family home has a 25-foot front yard, 10-foot side yard and 25-foot rear yard, but those figures should not be applied to another district or use.24 Lot coverage also depends on the district; the cited 50% principal-building limit applies specifically in the I-2 Heavy Industrial District.25 Floodplain development has a separate county review and may require federal, state or Iowa Department of Natural Resources approvals.26

Before dividing a tract, note that Iowa requires a subdivision plat when land is split into three or more parcels without a recorded plat of survey, subject to statutory exceptions.27

How do septic and well permits work in Floyd County?

Floyd County Environmental Health issues private-sewage permits and inspects every system installed in the county.37 The septic permit costs $300 and must be paid to the County Sanitarian before work starts.6 Private wells also require a county permit; the published $200 fee is due before work begins.4

Only about 1.2% of Floyd County soils are rated without severe limits for a conventional septic drain field, making early site evaluation especially useful.28 Iowa requires an inspection before qualifying transfers of buildings with one through four dwelling units served by private sewage, subject to statutory exceptions.29 Floyd County Environmental Health is at 101 S Main Street, Suite 206, Charles City, IA 50616, and can be reached at 641-257-6145.30

Can you live in an RV or tiny home in Floyd County, Iowa?

Floyd County's general rule for living in an RV or camping on private land outside a campground could not be confirmed. Ask Planning & Zoning whether the parcel's district allows the proposed use and what septic or floodplain approvals apply.15

The county ordinance lists commercial campgrounds and recreational vehicle parks as permitted uses in the C-R Commercial Recreation District, not countywide.31 In the floodplain overlay, an RV that is fully licensed and ready for highway use and stays on the site fewer than 180 consecutive days is exempt from anchoring and elevation rules; a longer stay or a vehicle not ready for the road must meet the standards for factory-built homes.31

A specific tiny-home occupancy rule could not be confirmed, but new dwellings must be on a permanent foundation and have an average main-body width or length of at least 24 feet.9 Iowa law also requires a county to allow at least one accessory dwelling on a lot with a single-family residence in a zoning district where that home is a permitted use, up to 1,000 square feet or 50 percent of the main home's size, whichever is larger, and the unit must meet state building regulations.32 Ask Planning & Zoning how the district rules apply to your parcel.15 Iowa counties may not reject a residential structure solely because it is a manufactured home when it meets the same permanent-foundation, setback and minimum-square-footage standards as a site-built home on that lot.33 Floyd County's RMH district is for manufactured-housing parks only and does not set placement rules elsewhere.34

Building a home in Floyd County, Iowa: what are the steps?

  1. Ask Floyd County Planning & Zoning for the parcel's district, allowed use, setbacks and minimum lot size.21
  2. Resolve any subdivision, rezoning, variance or conditional-use review that must precede the building permit.2
  3. Submit the complete building-permit application, site plan and scaled site information.11
  4. Arrange permits for private sewage and any private well before work begins.64
  5. Confirm that the proposed driveway meets Floyd County policy and obtain an Engineering Office permit for work within secondary-road right-of-way.3536 A driveway onto an Iowa primary highway needs a permit from the Iowa DOT district office instead.37
  6. Complete county floodplain review and any required outside approvals if the site is regulated.26
  7. Wait for the issued building permit or zoning certificate before starting regulated improvements.10

What should you check before buying land in Floyd County?

Confirm the parcel's zoning district, permitted use, setbacks, minimum lot size and any need for a conditional-use hearing with Floyd County Planning & Zoning.21 Check floodplain status because regulated development requires county review and may also need Iowa Department of Natural Resources approval.26

Have Environmental Health evaluate septic and well feasibility early: only about 1.2% of county soils are rated without severe limits for a conventional drain field, and county permits cover private sewage systems and wells.2834 Confirm legal road access and ask Engineer / Secondary Roads about a new driveway or extension within secondary-road right-of-way.35 For budgeting context, the median property-tax bill is about $1,854 per year and the effective rate is about 1.4%, though individual assessments differ.3839

Watch-outs

  • Do not assume an agricultural building bypasses every review; Floyd County's agricultural exemption requires an application and does not cover floodplain, septic or well rules.12
  • Do not rely on a seller's septic assurances alone; qualifying transfers of property with private sewage systems require a state time-of-transfer inspection, subject to exceptions.29
  • Floyd County's general rule for living in an RV, camping and tiny-home occupancy outside a campground could not be confirmed; ask Planning & Zoning about the parcel and proposed use before buying.15
  • The county ordinance and Iowa law differ on whether a farm building must file an exemption application, so confirm with Floyd County Planning & Zoning before building on the strength of an agricultural exemption.1216

    • 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.
