Does Reinbeck have zoning, and what does it mean for lots and setbacks?

Reinbeck, Iowa has its own zoning code, Chapter 165 of the city's ordinances, covering land inside city limits1. The code lists agricultural (A-1), residential (R-1 to R-4), commercial, industrial and floodplain overlay districts4. Rules depend on the district:

  • R-1 residential: single-family lots need at least 8,712 square feet and 70 feet of width5. Required yards are 25 feet in front and 30 feet at the rear of a dwelling, and 7 feet on the side of a one-story dwelling8. Principal buildings top out at 45 feet and 3 stories9.
  • A-1 agricultural: the minimum lot is 10 acres and 200 feet wide6. Front and rear yards are 75 feet10. Plats of subdivision are not permitted in A-16.

Reinbeck's A-1 district allows no more than one mobile home per parcel11. We could not confirm the city's rules on RVs, tiny homes or minimum house size; ask the City of Reinbeck at (319) 788-64042.

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

The City of Reinbeck requires a building permit if you are erecting, altering or extending a structure, and none for re-roofing, siding, replacing sidewalks or existing steps, or replacing windows or doors2. Applications go to City Hall in writing with plans, specifications and the fee2. City Hall is at 414 Main St, Reinbeck, IA 50669, phone (319) 788-64042. The city publishes a building permit and fee schedule on its permit page, and a separate application for a variance2.

We could not confirm which building code the city enforces, how inspections and certificates of occupancy work, or whether owner-builders get any exemption. Ask City Hall whether a certificate of occupancy is needed before you move in. Iowa's contractor registration law does not treat a person working on their own property as a contractor7, but that is not stated to waive permits or inspections.

How do septic permits and wells work in Reinbeck?

Iowa requires a construction permit before any private sewage disposal system is installed or altered3, and new private wells need a permit as well12. Outside city limits, the Grundy County Environmental Health Office issues septic and well permits13. We could not confirm whether the city or the county handles septic permits for an address inside Reinbeck, or whether a new lot must connect to city sewer. Ask City Hall and the county office before you plan a septic system or well.

For new subdivisions, the city requires public water and sanitary sewer built by the developer. A lot with an on-site well and septic needs at least two acres14.

How do you build a home in Reinbeck? The steps, in order

  1. Call City Hall at (319) 788-6404 to confirm your parcel's zoning district under the city zoning code12.
  2. Check the district's lot size and setbacks against your plans4.
  3. Ask City Hall whether public sewer and water serve the lot, and who permits septic or a well if not3.
  4. Apply in writing for a building permit with plans, specifications and the fee2.
  5. Ask about inspections and a certificate of occupancy before occupying the home; we could not confirm those rules.

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

The City of Reinbeck's zoning applies only inside city limits. For land outside them, Grundy County's page covers the county's rules for unincorporated land. Iowa counties may zone only land outside city corporate limits15. Grundy County's farmland averages about $12,121 per acre16, and its effective property tax rate is 1.1%17. Before you buy, confirm the parcel's zoning district, floodplain overlay status, sewer or septic arrangement and certificate of occupancy requirements with the City of Reinbeck.

Watch-outs

  • Chapter 165 sets different lot and yard rules by district, so a lot's district decides whether the 8,712-square-foot R-1 figure or the 10-acre A-1 figure applies5.
  • We could not confirm the city's building code, inspection process, permit fees or rules on RVs and tiny homes; call City Hall at (319) 788-64042.
  • We could not confirm who issues septic permits inside city limits; ask both City Hall and the Grundy County Environmental Health Office13.
