Fort Madison, IA Zoning, Building Permits & Septic Rules

Fort Madison, Iowa has its own zoning ordinance, and a permit is required for each building project or work on a structure inside city limits¹². The city's Planning & Zoning Department reviews zoning matters³. Lee County, which has not adopted a county zoning ordinance, handles private well permits⁴. We could not confirm who issues septic permits inside the city.

Does Fort Madison have zoning, and what does it mean for lot size and setbacks?

Yes. The City of Fort Madison administers its own zoning ordinance, Title 10 of the city code, and no building or land may be used for a purpose the district does not permit¹. The code publishes residential, business, industrial, agricultural/residential and airport districts¹⁰. Check the district of the exact parcel before you buy.

In the R-2 one-family district, a detached home needs a lot of at least 9,000 square feet and 60 feet wide at the building line⁹. A one-story dwelling needs at least 1,000 square feet of ground floor area⁸. Buildings and structures, accessory buildings included, may cover no more than 30% of an R-2 lot¹¹.

Accessory buildings such as sheds and garages go in the side or rear yard, at least 5 feet from the rear property line and 3 feet from the interior lot line¹². Detached accessory buildings may not exceed 15 feet in height¹³. Sections 10-4-4 and 10-4-10 were amended in May 2026, so confirm current text with the city¹.

Do you need a building permit in Fort Madison, and who issues it?

A permit is required for each building project or work on a structure inside Fort Madison, except interior changes where no building permit is required under another code provision². The application goes to the zoning administrator for approval before a permit is issued¹⁴.

The Planning & Zoning Department also takes applications for floodplain development permits, rezonings, special use permits and subdivisions³. We could not confirm the city's separate building permit fees, inspections or adopted building code, so ask the Planning & Zoning Department which office handles them.³ Iowa's State Building Code applies in a local jurisdiction only where its governing body accepts it by ordinance¹⁵.

How do septic permits and wells work in Fort Madison?

Septic permits for new, rebuilt or altered on-site systems covered by Lee County Code Chapter 5-2 come from the Lee County Board of Health⁶⁷. Those systems are also subject to final inspection by the same authority¹⁶. We could not confirm whether a lot inside Fort Madison falls under that chapter or under a city rule, and the city's zoning code points to separate septic lot standards where septic tanks are proposed⁹. Call the Lee County Health Department at 319-372-5225 before relying on a septic system¹⁷.

New non-public water wells, major rehabilitation or reconstruction need a permit from the County Health Department, valid for six months from issuance⁴. Fees are set by resolution of the administrative authority¹⁸.

Can you live in an RV or tiny home in Fort Madison?

We could not confirm. The city's zoning chapter lists sections on trailers and mobile homes and on accessory dwelling units, but we could not confirm their rules for RVs, tiny homes, manufactured homes or camping inside city limits. Ask the Planning & Zoning Department before buying with that plan³. Outside city limits the answer differs: Lee County has no county zoning, so see the Lee County page for unincorporated land⁵.

Building a home in Fort Madison: the steps, in order

Find the parcel's zoning district with the Planning & Zoning Department³.
Check lot size, yard and floodplain rules; construction in or adjacent to a floodway or floodplain is restricted¹⁹.
Submit the permit application to the zoning administrator¹⁴.
Ask the city which office handles building permits and inspections, since we could not confirm them.
Contact the Lee County Health Department about septic and wells¹⁷.

What stays with Lee County, and what should you check before you buy?

Lee County has not adopted a zoning ordinance, so its rules apply to unincorporated land, not to Fort Madison⁵. Septic and well permits are county health matters⁶⁴. Lee County's effective property tax rate is 1.5% and its median property tax bill is $1,855 a year²⁰²¹. Typical home value in the county is $128,725²².
