Zoning, building permits and septic rules in Wyoming, Iowa

Wyoming, Iowa (Jones County) adopts and enforces its own zoning ordinance, Code Chapter 1651. Building permits come from the City of Wyoming's building and inspections department, not from Jones County2. Septic is the open question: Jones County's septic rules are run by its Environmental Sanitarian3, but we could not confirm how they apply inside city limits.

Does Wyoming, Iowa have zoning, and what does it mean for lot size and setbacks?

Yes. The City of Wyoming adopts and administers its own zoning ordinance, Chapter 165 of the city code1. The chapter sets up R-1, R-2, RM, C, C-1 and I-1 districts plus an R-FB overlay1. Jones County's separate zoning ordinance covers only land outside city limits9, so the county's rules do not govern a lot inside Wyoming.

In R-1, the main single-family district, a lot should be at least 6,000 square feet and 50 feet wide, with one dwelling per lot5. Required yards are 15 feet in front, 10 feet in the rear and 5 feet on each side6. Buildings and accessory buildings together may cover no more than 40% of an R-1 lot10. R-1 buildings are limited to 2 stories or 30 feet unless side yards grow, and never more than 50 feet11.

In the RM multiple-family district, each dwelling unit needs at least 1000 square feet of living space and structures may cover up to 75% of the lot1213. The district map is a certified copy kept by the city clerk, so ask City Hall which district a parcel sits in4.

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

Yes. The City of Wyoming's building permits and inspections department issues building permits and conducts inspections inside city limits2. A building permit is required before any excavation for, or construction of, a building2. Fences, decks, sidewalks, patios, driveways and dog runs need permits as well2. The city asks applicants to allow 10 days for approval2.

A lot in the mapped floodplain needs a permit from the state and Jones County in addition to the city's2. Jones County's floodplain permit is administered by its Emergency Management Coordinator14.

Iowa's state building code applies in a city only where the local governing body accepts it, and permits are administered under local ordinance15. We could not confirm which building code Wyoming enforces, so ask City Hall which code edition your plans must meet. Owner-builders should note that Iowa's own-property exemption covers contractor registration only, not building permits or code compliance16.

How do septic and sewer work inside Wyoming, Iowa?

Sewer comes first. An owner of a building used for human occupancy that abuts a street, alley or right-of-way with a public sewer must connect, at the owner's expense, within 60 days of official notice from the city7. The duty applies only if the public sewer is within 100 feet of the property line and can carry sewage by gravity7.

Septic is county territory. Jones County's septic rules name the county Environmental Sanitarian, or an agent of the Board of Health, as the Administrative Authority3. The county requires a septic permit before work starts, and issues none when the property is within 200 feet of a public sewer17. Iowa also requires a certified septic inspection before most ownership transfers18.

Wyoming's city code lists a chapter on on-site wastewater systems, but we could not confirm what it says, so ask Jones County Environmental Health8 and City Hall before buying a lot without sewer. Private wells need a county permit, with a $250 non-refundable application fee listed by the county19.

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

We could not confirm any rule on RV living, camping or tiny homes inside Wyoming city limits. Call City Hall at (563) 488-3970 before parking an RV on a lot or planning a tiny home2. Do not rely on the county's answer: Jones County's treatment of travel trailers as temporary, non-permanent dwellings is part of its zoning ordinance for land outside city limits20.

Accessory dwellings have a statewide rule. Iowa law now requires cities to allow at least one accessory dwelling unit on a lot with a single-family home, in a district where single-family homes are allowed, up to 1,000 square feet or 50 percent of the house, whichever is larger21. We could not confirm how Wyoming's code applies this.

Building a home in Wyoming, Iowa: the steps, in order

  1. Call City Hall at (563) 488-3970 to confirm the lot's zoning district and whether sewer reaches it24.
  2. Check the district's lot size, setbacks and lot coverage; R-1 sets 15 feet in front, 10 in back and 5 on each side6.
  3. If sewer is within 100 feet of the property line, plan to connect; if not, contact Jones County Environmental Health about a septic permit78.
  4. If the lot needs a well, apply to Jones County for a private well permit19.
  5. Apply for the building permit from the city and allow 10 days for approval2.
  6. Check floodplain status; a floodplain lot needs state and county permits too2.
  7. Schedule inspections through the city2.

What stays with Jones County, and what should you check before buying in Wyoming?

Jones County's zoning, subdivision and land-use rules cover only unincorporated land, so for property outside city limits use the Jones County page instead9. Inside Wyoming, septic and private wells stay with the county's Environmental Health office, and floodplain permits involve the county as well3192.

Before you buy, confirm the zoning district, sewer availability and floodplain status with the city. Countywide, USDA rates only 2.7% of soils as not limited for a conventional septic drain field, so a lot without sewer likely needs a site evaluation or engineered system22. Jones County's effective property tax rate is 1.3%23.

Watch-outs

  • Inside Wyoming, the city's zoning applies and the county zoning ordinance does not19.
  • We could not confirm which building code Wyoming enforces, whether it requires a certificate of occupancy, or its permit fees; ask City Hall at (563) 488-39702.
  • We could not confirm how septic permits work for a lot inside city limits; ask Jones County Environmental Health and the city before buying without sewer8.
  • The R-1 minimum lot area is worded 'should be' 6,000 square feet, so ask the city whether smaller lots can be approved5.
