Zoning, building permits and land rules in Redfield, South Dakota

Redfield, South Dakota requires a city building permit for every kind of construction, including concrete, with no minimum cost1. Inside city limits, the city's own zoning applies and Spink County's zoning ordinance excludes the city23. Septic authority inside city limits is unconfirmed; the state sets the on-site wastewater rules4.

Do you need a building permit in Redfield, SD?

Yes. The City of Redfield requires a building permit for all types of construction, including concrete, and there is no minimum construction cost; a permit is needed even if supplies and labor are free19. The city will not issue the permit until the required information is provided and the project meets city codes, and a variance or special exception can add 4–8 weeks1.

Fees are published by construction cost: $10.00 for work up to $5,000, rising in steps, with 1/10 of 1% of construction cost at $80,001 or more10. A permit is good for 2 years if work starts within 90 days10. Removing a building has its own permit, at $10.0010.

We could not confirm which building-code edition Redfield has adopted or whether the city inspects construction; ask City Hall before you design.

Who issues building permits in Redfield, and how do you reach them?

Redfield City Hall issues building permits for construction inside the city, during regular business hours911. Call 605-472-4550 or email [email protected]9.

Spink County Planning and Zoning handles permits for land outside the city, not for lots inside Redfield; the county's zoning ordinance excludes the area inside the city limits of Redfield3. Standalone electrical work follows state rules: a homeowner doing their own wiring needs an approved homeowner permit before starting12.

Does Redfield have zoning, and what does it mean for mobile homes, lot size and setbacks?

Yes. Redfield has its own zoning map, which labels Mobile Home (MH), Parks, Commercial, Highway Commercial, Industrial, Airport and Cemetery areas2. Spink County's ordinance does not cover the area inside Redfield's city limits3.

In the R residential district, a dwelling needs at least 900 square feet of floor area and a width of at least 20 feet6. Setbacks are at least 20 feet in front, 7 feet on each side and 25 feet in the rear13. Buildings may cover no more than 40 percent of the lot14 and may not exceed 35 feet in height15.

Mobile homes are prohibited in the R district, so look at the MH district for one5. We could not confirm how tiny homes or accessory dwellings are treated; ask City Hall9.

How do septic permits work inside Redfield?

We could not confirm who administers septic permits for lots inside Redfield city limits. The state's rules apply across South Dakota and are administered by the Department of Agriculture and Natural Resources (DANR), and local governments may add stricter rules416.

For a conventional system serving a single residence, DANR asks to be contacted before installing anything other than a conventional system, and installers must be certified by the South Dakota Plumbing Commission17. Ask Redfield City Hall whether your lot can connect to city sewer before planning a private system9. Soil context is county-wide: about 18.9% of Spink County soils are rated not limited for a conventional drain field, so many rural lots need a site evaluation or engineered system18.

Can you live in an RV or tiny home in Redfield?

We could not confirm a rule for temporary camping, RV occupancy or tiny homes on private land inside Redfield. The city's zoning materials set a minimum dwelling size of 900 square feet in the R district, which a typical tiny home would not meet6. Mobile homes are prohibited in the R district5. Call Redfield City Hall before buying a lot to live on in an RV or small structure9.

Building a home in Redfield: the steps, in order

  1. Confirm the zoning district of your lot on the city zoning map and check the district's size and setback rules2.
  2. Check the flood-hazard map; new construction in special flood-hazard areas must meet Chapter 17.56 standards and the floodplain administrator reviews development permits7.
  3. Apply for a building permit at City Hall and pay the fee11.
  4. If you need a variance or special exception, allow 4–8 weeks1.
  5. Contact DANR about the septic or sewer plan16.
  6. For owner-installed wiring, get the approved homeowner permit before starting; a final electrical inspection is required before occupancy19.

What stays with Spink County, and what to check before you buy?

Redfield sits in Spink County, whose zoning and permit rules apply to unincorporated land outside the city, not inside it3. Land outside the city limits needs a county building permit above a $2,500 improvement value20.

Spink County's effective property tax rate is 1.3%21. The county is rural, about 130 miles in a straight line from the nearest city of 100,000 or more22. Driveways onto state highways need a South Dakota Department of Transportation access permit23; we could not confirm a driveway rule inside city limits.

Watch-outs

  • We could not confirm the building-code edition, city inspections, certificate of occupancy or owner-builder rules inside Redfield; ask Redfield City Hall at 605-472-45509.
  • Redfield's published zoning standards cited here apply to the R residential district; other districts differ, so check your lot's district first6.
  • Floodplain development inside Redfield is regulated under Chapter 17.56 and needs review by the floodplain administrator7.
