Do you need a building permit in Shelby County, Indiana?
Unincorporated Shelby County requires building 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 building permits, but still need an Improvement Location Permit plus electrical and plumbing permits when applicable12. A rightful owner-occupant building a single-family dwelling may act as general contractor by filing a homeowner affidavit6. New buildings in the county inspection jurisdiction must comply with the Indiana State Building Code1314. Building inspections must be requested 24 hours ahead; the published sequence covers footing, foundation, framing and final inspections, although not every project necessarily follows that same sequence15. Shelbyville issues its own building permits, and Edinburgh, which lies mainly in Johnson County and reaches into Shelby County, also issues its own building permits1617. The Shelby County Health Department handles systems not connected to a regulated sewage facility; Shelbyville also requires a private sewage-disposal permit from its Board of Public Works and Safety where public sewer is unavailable1819.
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 317-392-648020. Shelby County generally processes electronic building permits in one business day, but issuance waits for Site Plan Committee approval21. Shelby County publishes separate Plan Commission and Building Inspector fees; the listed new-dwelling charges are $220 for building, $165 for plumbing and $165 for electrical permits, while card payments carry a 4% transaction fee22. The Shelby County Plan Commission handles site-plan review, permitting, inspections and floodplain administration at 25 W. Polk Street, Room 201, Shelbyville; call 317-392-633823. The Shelby County Health Department handles residential onsite-sewage permits and environmental health review; call (317) 392-647024.
Does Shelby County have zoning?
Shelby County's Unified Development Ordinance and Official Zoning Map govern the county planning jurisdiction, while cities and towns administer their own planning jurisdictions2526. Shelbyville sets its own zoning, as does Edinburgh, the town mainly in Johnson County that reaches into Shelby County2728. The county Health Department remains the contact for onsite sewage systems not connected to a regulated facility, with an additional city private sewage-disposal permit in Shelbyville1819. Residential Estate requires a 2-acre lot, a 1,600-square-foot dwelling, 50-foot front and 30-foot primary-structure side and rear setbacks, and no more than 30% lot coverage8293031. Village Residential instead has a 6,500-square-foot lot minimum, 900-square-foot dwelling minimum, 25-foot front, 8-foot primary side and 20-foot rear setbacks, and 65% maximum lot coverage9323334. Accessory-structure setbacks also vary by district, so ask the Plan Commission to identify the parcel's jurisdiction and zoning before siting a building3523. In both RE and VR, primary structures have a 35-foot height limit and accessory structures a 20-foot limit3637.
How do septic permits work in Shelby County?
The Shelby County Health Department issues permits for residential and commercial sewage-disposal systems that are not connected to a regulated sewage facility18. A new home needs a septic permit unless it uses sewer and water from the Waldron Conservancy District4. County-regulated septic work must be inspected and signed off, and septic approval is part of the new-home occupancy process38. 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 contingency11. Public sewer is not required in Residential Estate, but a private well is allowed there only when public water is unavailable; Village Residential requires public sewer and water3940. We could not confirm a separate private-well permit requirement; ask the Health Department before relying on a well24.
Can you live in an RV or tiny home on your land in Shelby County?
An RV may not be used as living quarters in unincorporated Shelby County's zoning jurisdiction7. Manufactured and mobile homes are permitted uses in the Manufactured Home Park district, where each unit needs at least 700 square feet, lot coverage is limited to 65%, and public sewer and water are required10414243. Shelby County requires a Board of Zoning Appeals variance for a tiny home classified as a detached secondary dwelling or an attached dwelling unit; the Board typically grants temporary occupancy in hardship cases44. The county FAQ does not define a general tiny-home category45. For accessory dwellings used as short-term rentals, the UDO requires legal establishment by the Board of Zoning Appeals and compliance with residential building codes46. Ask the Plan Commission to classify the exact structure and proposed use before buying or building23.
What are the steps to build a home in Shelby County?
- Confirm the planning jurisdiction, zoning district and buildable-lot status; creating a new lot requires the platting process47.
- Arrange soil samples and obtain a septic permit unless the Waldron Conservancy District exception applies214.
- Submit the site plan by noon Tuesday for Thursday review; permits wait for Site Plan Committee approval21.
- Obtain a Shelby County Highway Department access permit for a county-road entrance; the county access fee is $2048. A state-highway entrance also needs INDOT permission4950.
- Obtain the required improvement-location, building, electrical and plumbing permits, and file a homeowner affidavit if the rightful owner-occupant will serve as general contractor216.
- Schedule inspections 24 hours ahead and do not pour foundation concrete before inspection2.
- Complete the required inspections, including septic inspection, and receive a temporary or final certificate of occupancy before moving in513.
What should you check before buying land in Shelby County?
Before buying a small parcel, ask the Shelby County Plan Commission to verify building-lot eligibility: the usual minimum is 2 acres, but lots established before 2008 may be grandfathered if the home meets other zoning requirements5223. Creating a new lot requires platting; a sale or proposed split does not establish building-lot eligibility47. Check septic feasibility before closing because only 0.3% of county soils lack severe limitations for a conventional drain field11. Construction or grading in a designated Flood Hazard Area needs a county floodplain permit, and floodway development also needs Indiana DNR Division of Water approval53. We could not confirm temporary-camping rules, private-well permit requirements or off-grid sanitation options; ask the Plan Commission about camping and floodplain review, and the Health Department about wells and sanitation2324.

- Share of soils USDA rates "not limited" for a conventional septic drain field (SSURGO). A strict rating: the median county is about 6% and a tenth of counties are 0%, so a low figure means most lots need a site evaluation or an engineered system, not that septic is impossible.
