Buchanan County, Iowa Building Permit Guide

In unincorporated Buchanan County, Planning & Zoning, Environmental Health in the lower level of the courthouse, 210 5th Ave NE, Suite I, Independence (319-334-2873), issues the zoning compliance permit that the 2026 zoning ordinance requires before a non-farm building is put up or structurally altered, and the floodplain, septic and well permits. A new septic permit costs $250 and a well application $275; electrical permits come from the state.

What requires a permit in unincorporated Buchanan County?

Zoning Ordinance 20-01, adopted by the Board of Supervisors on April 13, 2026, says no building put up or structurally altered may be occupied or used until the Zoning Administrator has issued a zoning compliance permit, and no change of use may be made without one. The permit must be obtained before construction, moving a building in or structural alteration starts, and an occupancy permit is needed before a new building or use is occupied.

The department’s older FAQ page answers the building permit question more narrowly: it says a permit is needed only for building in the FEMA special flood hazard area or near the Independence airport, plus separate permits for wind turbines, towers over 60 feet, septic systems and wells. The 2026 ordinance is the adopted rule and requires the zoning compliance permit for non-farm buildings across the unincorporated county, so call the office before relying on the FAQ.

What the county decides and what the state holds

Buchanan County adopted zoning in 1974 and joined the National Flood Insurance Program in 1989, which brought a floodplain ordinance for rural flood plains. Ordinance 20-01 repealed chapter 50 of Title VI of the county code and any conflicting rules, after Planning and Zoning Commission review on March 4, 2026 and hearings on March 30, April 6 and April 13; a 2026 Comprehensive Land Use Plan is posted with it. The ordinances the county posts include no building code, the department says the county has no rules on the outside look of dwellings, and a draft battery energy storage ordinance (26-01) is posted; the department also shared material from a January 27, 2026 Iowa State University workshop on siting and permitting battery storage. Energy code, trade licensing and electrical permits are state matters, and state electrical permits have been required in the county since 2010.

Buchanan County building department: who handles permitting

Amber Lorenzen is the county’s Sanitation, Floodplain and Zoning Administrator, so zoning, floodplain, septic and well permits all go through one courthouse office. Environmental Health, set up in 1975, is a division of Buchanan County Public Health under the Board of Health and serves both rural and non-rural properties for wells, septic systems and public health nuisance complaints. Secondary Roads lists its forms and permits as applications in the county’s GeoPermits system, and the GIS Coordinator issues 911 addresses.

Cities in Buchanan County

The county ordinance covers only unincorporated land. To find out whether an address is in the county or a city, call the zoning office or the city hall, which can check GIS aerial maps.

Buchanan County permit types

Planning & Zoning posts printable forms for the zoning permit, the floodplain development permit, floodplain variances, variances, rezonings, business and home occupation permits, property line adjustments and minor and major subdivisions; Environmental Health posts the well permit and the new, repair and new-construction septic applications. The county home page also links its GeoPermits online permit system.

Residential permits

The zoning permit application asks for the property’s address and legal description, the zoning district, the existing and proposed use, and a site or plot plan with lot dimensions and the size, shape and location of buildings, then compares the site’s height, lot area, width, setbacks and parking with the ordinance minimums. A lot used for a home must have at least 40 feet of frontage on a street or its own 20-foot access easement (24 feet when two houses share one). Accessory buildings go in the side or rear yard, at least 5 feet from the house, no taller than 28 feet, and not before the house foundation is finished.

Commercial permits

Businesses use the zoning permit in the C, C-M and M districts, and home-based businesses use the business or home occupation permit, $65 a year. Animal confinements of 500 animal units or more are regulated by the Iowa DNR, whose regional office is at 563-927-2640, while the Board of Supervisors reviews confinement applications.

For tenant improvements and new commercial builds, Alliance handles commercial permit expediting through issuance. More on this: commercial building permits explained.

What comes before the building permit

• Zoning hearings. Rezonings go to the Planning and Zoning Commission and variances and special exceptions to the Board of Adjustment; the 2026 schedule sets monthly filing deadlines, applications must be filed by noon on the deadline, and nothing is processed until the fee is paid.
• Floodplain. Construction in the flood plain needs a county floodplain development permit and an Iowa DNR permit; an elevation certificate comes from a certified engineer or surveyor.
• Septic and well. Well applications and fees are due before construction, and new septic systems need a county permit.
• Wind turbines. Turbines are governed by chapter 54 of the county code, the wind turbine ordinance, which had an amendment read in August and September 2022.
• Address. New houses get a 911 address and sign from the GIS Coordinator.

Buchanan County permit costs and fees

Ordinance 20-01 leaves zoning fees to a schedule adopted by Board of Supervisors resolution and kept on file in the Zoning Administrator’s office; it covers rezoning, variance, special exception, zoning compliance permit, home occupation and appeal fees, but the schedule is not posted online. Environmental Health posts its 2025 fees, payable to the Buchanan County Treasurer.

Grants through Environmental Health cover well plugging up to $700, cistern plugging up to $400, well reconstruction up to $2,000 (not the pump), well shocking up to $400 and well assessments up to $600, while funds last. Building without a required permit is a county infraction, and the ordinance also allows misdemeanor fines of $750 to $1,000 per day or up to 30 days in jail. When a zoning permit expires, the holder must apply again and pay the fee for the new permit, which is also set by resolution. Business and home occupation permits are renewed by the Zoning Administrator when they expire.

Trade permits and who may pull them

Buchanan County’s pages describe no county electrical, plumbing or mechanical permit and no construction inspections. State of Iowa electrical permits have been required in the county since 2010, and the department refers callers to the state electrical inspectors; trade licenses are state licenses, and contractors earning $2,000 or more a year from construction register with the Department of Inspections, Appeals, and Licensing.

• Septic systems. Environmental Health issues and inspects permits for new septic systems, with separate forms for a new system, a repair and new construction; the office posts lists of certified septic inspectors, tank pumpers, bonded installers and engineers and surveyors.
• Wells. Permits are required before installing any private well, including sandpoints, geothermal and irrigation wells; the office checks the location and setbacks, wells must be built to the county code and state rules, and the office posts a list of certified well drillers.
• Old wells. Abandoned wells must be plugged within 90 days, by a DNR-certified contractor or by the owner under Environmental Health supervision.

How to apply for a Buchanan County permit

Review, corrections and what causes delay

The Zoning Administrator issues permits to complying applicants; missing sketches, a lot without the required road frontage, or a site in the flood plain that also needs Iowa DNR approval are common reasons for delay. Projects needing a rezoning, variance or special exception must meet the monthly filing deadline and wait for the commission or board meeting.

Inspections in Buchanan County

The county does not inspect framing, plumbing or mechanical work. A zoning permit becomes void one year after issue if work has not started, the holder must finish within 12 months, and before a new building or use is occupied the Zoning Administrator issues an occupancy permit confirming it meets county ordinances.

Environmental Health inspects new septic systems and wells under its permits and tests private wells, usually on Wednesdays. Wiring is inspected by state electrical inspectors under the state permit. In the flood plain, an elevation certificate from a certified engineer or surveyor documents the building’s height, and a letter of map amendment can show that a lot or house sits above the base flood elevation.

Iowa building code

Buchanan County enforces Zoning Ordinance 20-01, its subdivision ordinance, its floodplain rules and its well and septic rules, and none of the ordinances it posts is a building code for the unincorporated area. FEMA’s Community Status Book lists Buchanan County as participating in the National Flood Insurance Program, with flood maps effective December 30, 2020.

Iowa lets most cities and counties adopt the state building code, another code or none (a city of more than 15,000 must enforce at least the state code), but the energy, accessibility, fire, plumbing, mechanical and electrical rules apply statewide. Iowa rules

Buchanan County permit search and official resources

Ordinance 20-01 has the Zoning Administrator keep the records and copies of permits as a matter of public record; ask the courthouse office for a past zoning, floodplain, septic or well permit. Ordinances, forms and the 2026 meeting schedule are posted on the department pages.
