Does Greensburg, Indiana have zoning, and what does it mean for RVs, lot size and setbacks?
Yes. Greensburg administers its own zoning districts inside city limits under its Unified Development Ordinance2. The base districts run from C-1 conservation through R-1 to R-4 residential, business, and industrial districts, plus a historic overlay9.
Rules differ by district. In R-1, a single-family lot needs at least 7,500 sq ft and 70 feet of frontage10; in R-2 the minimums are 5,000 sq ft and 55 feet11; in C-1 conservation a lot needs at least 1 acre and 150 feet of frontage12. Side-yard setbacks for a primary structure are 10 feet in R-113, 6 feet in R-214 and 25 feet in C-115. Primary structures top out at 35 feet in R-116.
Minimum living area is 900 sq ft in R-16 and 800 sq ft in R-27. Outside a designated RV park or campground, an RV may be a temporary residence for no more than 29 days, and only in districts that allow it, including R-1 and R-25. Manufactured home parks are a use in R-4 with a development plan17. We could not confirm a tiny-home rule; ask the city Building, Planning and Zoning office18.
Do you need a building permit in Greensburg, and who issues it?
Yes. Construction inside Greensburg is prohibited without a valid building permit from the city's Building Commissioner1. The city adopts the Indiana building codes by reference, including the Indiana Residential Code, and the Building Commissioner enforces them19. The city's Building, Planning and Zoning office issues improvement location permits for new residential construction and remodeling18.
The application goes to the Building Commissioner with plans, specifications and a fee set by city ordinance20. A permit can be withheld or revoked if the structure does not conform to zoning1. Inspections apply to all construction whether or not a permit was required21, and no one may occupy a building without a certificate of occupancy from the Building Commissioner8.
How do septic permits work in Greensburg?
Septic is not handled by the city's building office. Decatur County's Health Department permits and inspects residential on-site sewage systems4, and county environmentalists inspect sites before construction and during installation22. The county lists a new septic permit at $600 and a repair, replacement or expansion at $300, subject to change3. Contact the23 office.
We could not confirm which Greensburg addresses are on city sewer and which need a septic system, so ask the city office and the health department before relying on either. Indiana does not allow drywells or cesspools as on-site sewage treatment24.
Building a home in Greensburg: the steps, in order
- Confirm the lot's zoning district and its lot-size, setback and minimum-size rules with the city Building, Planning and Zoning office18.
- Settle water and sewer: ask the county health department about septic if the lot is not on city sewer4.
- Apply to the Building Commissioner for a building permit with plans and specifications20.
- Build to the Indiana codes the city has adopted, and expect inspections1921.
- Get a certificate of occupancy before anyone moves in8.
What stays with Decatur County, and what to check before you buy
Land outside Greensburg city limits follows Decatur County's rules instead; see the Decatur County page. Septic stays with the county health department for every address4. A driveway onto a state highway needs INDOT permission25. Floodplain development inside a floodway needs a state DNR permit26.
Decatur County's farmland value is about $9,415 per acre27, and its effective property tax rate is 0.6%28. Few county soils rate well for a conventional septic drain field, so expect a site evaluation29.
Watch-outs
- We could not confirm Greensburg's building permit fee schedule, owner-builder rules or driveway and floodplain rules for city lots; ask the Building, Planning and Zoning office18.
- The zoning rules above come from the city's UDO as amended through May 2024, and later amendments may apply2.
- Rules for temporary camping, tent living and wells inside city limits were not confirmed; ask the city office and the county health department23.
