Do you need a building permit in Brown County, Indiana?
Yes. Brown County requires a building permit before a person or business erects, constructs, alters or repairs a building or structure1. Plans must conform to the adopted Indiana Building Code, and the Building Department may require corrections before issuing the permit13. Brown County requires permit holders to request setback, trench-and-footing, rough-in and final inspections with two business days or 48 hours of notice14. A final inspection is required, and the premises may not be occupied until the Brown County Building Commissioner issues a certificate of occupancy15. Since July 20, 2026, pole-structure residences, barndominiums and specified conversions or additions intended for people require structural framing plans stamped by an Indiana-licensed engineer or architect; the notice excludes accessory pole structures used as agricultural barns, storage barns, garages or workshops10.
Who is the Brown County building department, and how do you reach them?
The Brown County Building Department is at 201 Locust Lane, 2nd Floor, Nashville, IN 47448, and its phone number is 812-988-549010. The Building Department handles building permits, plan review, contractor records and construction inspections10. Brown County's published application process calls for project and ownership information, a site plan, zoning and floodplain compliance, Health Department approval when applicable, and a driveway permit when applicable16. Residential applicants submit two identical plan sets, and the Building Department may require corrections before issuing the permit16. Brown County also requires contractors to obtain an annual county contractor license16. The Area Planning Commission shares the Locust Lane address and phone number and handles zoning matters17. Ask the Building Department how its one-permit workflow applies to the exact parcel, because its webpage describes that system with unclear incorporated-area wording10.
Does Brown County have zoning?
Yes. Brown County's zoning ordinance applies to unincorporated Brown County, while the Town of Nashville has a separate zoning ordinance2. Brown County does not post parcel-specific zoning maps online; contact the Area Planning Commission for the parcel's district18. Buildings must satisfy applicable setback and offset requirements, and permitted projects receive a setback inspection19. If a lot is smaller than 2 acres, the building must be staked before the footing is dug19. Dividing or re-dividing land outside Nashville requires primary and secondary plat approval by the commission before the land is considered subdivided, followed by filing the approved plat with the County Recorder11. A short-term rental outside Nashville requires a special exception and Board of Zoning Appeals approval, with at least 250 feet to the nearest residence and at least 1,320 feet to the nearest short-term rental20. Nashville uses its own zoning to decide short-term-rental eligibility20.
How do septic permits work in Brown County?
The Brown County Health Department issues permits for new and repaired on-site wastewater systems and specifies the required system and location4. The department reviews a certified soil analysis to determine the soil profile, loading rate and site suitability9. Every septic installation receives an inspection for compliance with Indiana rule 410 IAC 6-8.3, and a system diagram stays on file5. The Health Department is at 200 Hawthorne Drive, PO Box 281, Nashville, IN 47448; call (812) 988-2255 or email [email protected]21. Brown County's mapped soils show 0% rated without severe limitations for a conventional septic drain field, making a site-specific soil evaluation an early purchase contingency rather than a formality89. Indiana requires a compliant septic tank and soil-absorption system when a dwelling cannot connect to sanitary sewer, and the state prohibits drywells and cesspools for on-site sewage treatment22.
Can you live in an RV or tiny home on your land in Brown County?
Brown County prohibits using a camper or recreational vehicle for long-term living or as a permanent dwelling because those units do not meet the county's residential square-footage and building-code requirements3. Brown County has not published a confirmed rule for temporary camping on private property, so ask the Area Planning Commission before staying in an RV while building17. A tiny home is not automatically treated like an RV, but we could not confirm a tiny-home-specific occupancy rule or the exact minimum dwelling size; give the Planning Department the proposed floor area, foundation type and construction method before buying23. A built tiny home still falls within Brown County's general permit, code, zoning, setback and septic framework113194. Indiana's campground rules address regulated campgrounds rather than authorizing residential RV use on an individually deeded lot24.
What are the steps to build a home in Brown County?
- Ask the Area Planning Commission for the parcel's zoning district and confirm setbacks, floodplain or geologic-hazard review, and any special approvals1825.
- Arrange the Health Department's septic site evaluation before fixing the house location9.
- Obtain the proper driveway approval before the building permit if new construction connects to a county, state or Nashville-maintained public road26.
- Prepare the site plan, ownership documents and two identical residential plan sets, plus any required health, zoning and floodplain approvals16.
- Apply through the Building Department and confirm current submittal standards and fees; the published residence fee is $125 plus $0.07 per square foot27.
- Call for the setback, trench-and-footing, rough-in and final inspections with two business days or 48 hours of notice14.
- Complete the driveway, culvert, septic and drainage work, pass final inspection, and receive the certificate of occupancy before moving in15.
What should you check before buying land in Brown County?
Make septic feasibility the first contingency: 0% of Brown County's mapped soil is rated without severe limitations for a conventional drain field, and the Health Department uses certified soil analysis to decide site suitability89. Brown County is 90% wooded, while 39% of its land has a slope of 15% or less, so inspect the proposed house, septic and driveway locations together2829. For access from a county road, the Highway Department accepts applications at 711 Greasy Creek Rd, Nashville, IN 47448, and the published private-driveway application fee is $6530. A connection to a state highway instead goes through INDOT's electronic permit system31. Ask the Area Planning Commission for the zoning district and whether the parcel is in a floodplain or geologic-hazard area before committing to a building site1825. Brown County's effective property-tax rate is about 0.5%, and its median annual property-tax bill is about $1,1413233.
Watch-outs
- The Building Department describes its one-permit system with unclear incorporated-area wording, so ask how that workflow applies to your specific parcel10.
- Brown County's exact minimum dwelling size and its rule for temporary camping could not be confirmed; ask the Area Planning Commission before planning a tiny home or an RV stay17.
- An owner-builder exemption from Brown County's contractor requirements could not be confirmed; ask the Building Department before planning to build without a licensed general contractor12.
