Do you need a building permit in Shelby County, Indiana?
Yes. Unincorporated Shelby County requires permits for new dwellings and commercial structures, remodels and additions, decks, pools, and accessory structures over 200 square feet1. Agricultural structures in agricultural zoning districts are exempt from the building permit, but still need an Improvement Location Permit plus electrical and plumbing permits when applicable11. A rightful owner-occupant building a single-family dwelling may act as general contractor by submitting a homeowner affidavit and accepting responsibility for code compliance and subcontractor risks6. The county requires footing, foundation, framing and final inspections, requested 24 hours in advance; foundations may not be poured before inspection3. Land inside a city or town's legally established planning jurisdiction is outside the county ordinance, so use that municipality's permit authority instead2.
Who is the Shelby County building department, and how do you reach it?
The Shelby County Building Inspector serves unincorporated Shelby County and the Town of Fairland from 25 W. Polk St. in Shelbyville; call 317-392-648013. The office page says permits are generally processed and issued in one business day13. The Shelby County Plan Commission handles zoning, site plans, subdivisions and floodplain administration at 25 W. Polk Street, Room 201, Shelbyville; call 317-392-633814. Septic approval goes through the Shelby County Health Department at 20 W Polk St, Suite 202, Shelbyville; call (317) 392-64701516. For a county-road entrance, the published new-home process directs applicants to obtain an access permit from the Shelby County Highway Department; a state-highway entrance also needs INDOT approval17.
Does Shelby County have zoning?
Yes. Shelby County's Unified Development Ordinance applies outside the legally established planning jurisdictions of cities and towns2. District matters: Residential Estate lots require at least 2 acres and primary dwellings at least 1,600 square feet, while Village Residential lots require at least 6,500 square feet and dwellings at least 900 square feet188199. Residential Estate primary structures have 50-foot front and 30-foot side and rear setbacks; Village Residential primary structures have 25-foot front, 8-foot side and 20-foot rear setbacks2021. Both districts cap primary structures at 35 feet and accessory structures at 20 feet2223. Confirm the parcel's district with the Plan Commission before designing the site plan14.
How do septic permits work in Shelby County?
A new home in Shelby County needs a septic permit unless it uses sewer and water from the Waldron Conservancy District5. The Shelby County Health Department handles the health review for county permit applications16. Septic inspection and approval must be complete before the final certificate of occupancy is issued24. Only 0.3% of Shelby County soils are rated without severe limitations for a conventional drain field, so make soil evaluation and septic feasibility an early purchase contingency12. Utility rules also depend on zoning: public sewer is not required in the Residential Estate district, while a private well is permitted there only when public water is unavailable25. Village Residential and Manufactured Home Park districts require public sanitary sewer and water2627. We could not confirm a separate county private-well permit requirement; ask the Health Department before relying on a well15.
Can you live in an RV or tiny home on your land in Shelby County?
Shelby County prohibits using a recreational vehicle as living quarters in the county Unified Development Ordinance jurisdiction7. We could not confirm a separate tiny-home category, but any proposed dwelling must meet the rules for its zoning district, obtain required building and land-use approvals, and complete inspections before occupancy124. The minimum dwelling size is 1,600 square feet in Residential Estate, 900 square feet in Village Residential, and 700 square feet per manufactured-home unit in a Manufactured Home Park district8910. Manufactured and mobile homes are expressly permitted in the Manufactured Home Park district, subject to that district's site and utility standards28. A short-term-rental accessory dwelling must first be legally established by the Board of Zoning Appeals and meet residential building-code requirements29.
Building a home in Shelby County: the steps, in order
- Confirm the planning jurisdiction, zoning district and buildable-lot status; creating a new lot requires platting, while some lots existing before 2008 may be grandfathered230.
- Arrange soil samples and septic review, unless the Waldron Conservancy District exception applies315.
- Submit the site plan by noon Tuesday for the following Thursday review31.
- Obtain the county-road access permit, plus INDOT approval for a state-highway entrance17.
- Obtain the Improvement Location Permit and building, electrical and plumbing permits; file the homeowner affidavit if the rightful owner-occupant will serve as general contractor316.
- Schedule required inspections 24 hours ahead and do not pour a foundation before inspection3.
- Complete the site-development, septic and final inspections, then receive the certificate of occupancy before moving in31244.
What should you check before buying land in Shelby County?
Start with jurisdiction and zoning because lot area, dwelling size, setbacks, height and utility requirements change by district218192526. If the sale depends on splitting land, a new lot must go through platting; some lots in their pre-2008 configuration may qualify for grandfathering30. Test septic feasibility before closing because only 0.3% of county soils are rated without severe limitations for a conventional drain field12. Check flood mapping before choosing the homesite because all construction in county Flood Hazard Areas requires a Floodplain Development Permit32. Confirm legal road access and culvert needs because a new county-road entrance requires a Highway Department access permit, with additional INDOT approval on state highways17. We could not confirm a countywide water or sewer connection rule outside the district-specific standards, so ask the Plan Commission and serving utility about the parcel14.
Watch-outs

- Agricultural structures in agricultural districts may avoid a building permit, but still need an Improvement Location Permit and applicable electrical or plumbing permits11.
- A building may not be occupied until the required site visit and final inspection are complete and the certificate of occupancy is received4.
