Do you need a building permit in Putnam County, Indiana?
Yes. Construction covered by Putnam County's process needs an Improvement Location Permit or other required permit before work starts in county-administered areas1. The Building Department serves unincorporated Putnam County and the towns of Cloverdale, Bainbridge, Roachdale and Russellville1. Starting first triggers a fee equal to twice the current permit fee1. Indiana also applies its adopted statewide construction codes, including the Indiana Building Code and Indiana Residential Code, according to the structure and code category8. An owner building a dwelling or structure for personal use or occupancy may sign a Contractor Listing Exemption, but the signer remains responsible for construction, permits, fines and penalties5.
Who is the Putnam County building department, and how do you reach it?
The Putnam County Building and Planning Department issues building permits and handles zoning, inspections and floodplain administration in its jurisdiction9. Call (765) 301-9108, email [email protected], or visit the department at its listed Greencastle office9. The county page says its permit territory includes unincorporated Putnam County plus Cloverdale, Bainbridge, Roachdale and Russellville9. Property in the City of Greencastle should go to the city for zoning information10. For county-administered construction, check the permit itself for the required inspections and give the department at least 24 hours' notice; same-day inspections are unavailable11.
Does Putnam County have zoning?
Yes. The Putnam County Unified Development Ordinance covers all unincorporated real property and the incorporated towns of Bainbridge, Cloverdale, Roachdale and Russellville2. Greencastle directs zoning questions to its own city staff, so first confirm which jurisdiction controls the parcel10. Within the county UDO, lot size, setbacks, coverage and height vary by zoning district and use12131415. Agricultural residential setbacks, for example, are 50 feet in front and 25 feet at the side and rear13. The UDO's stated minimum dwelling sizes apply to multifamily units in specified residential districts, not as a single countywide minimum for every detached house16. Ask Planning to identify the current district before designing around any dimensional standard.
How do septic permits work in Putnam County?
The Putnam County Health Department administers both state and local on-site sewage rules17. A Health Department permit is required before construction begins on a new, repaired, replaced or upgraded septic system, and that approval must precede the county construction permit3. Call the Environmental Services Division at (765) 653-020318. The published packet lists a $225 fee for a new system along with an application, soil evaluation, plans, deed and plat3. A registered installer must notify the Health Department at least 2 business days before installation, and the department performs a final inspection19. Only about 4.2% of county soils are rated without severe limitations for a conventional drain field, so make septic feasibility an early purchase contingency20.
Can you live in an RV or tiny home on your land in Putnam County?
In residential districts governed by the Putnam County UDO, a parked or stored recreational vehicle or trailer cannot be used for living, sleeping or housekeeping, and connections to gas, electric, water or sanitary sewer service are prohibited4. The same rule allows one recreational vehicle or trailer to be stored in the open on a lot when the applicable side- or rear-yard setback is met4. We could not confirm a specific Putnam County tiny-home occupancy rule. Because the county has district-specific use, lot and dimensional standards, take the proposed tiny home's foundation, construction type and intended use to the Building and Planning Department before purchase6. An accessory dwelling is a different path: the UDO permits one on a parcel with a principal single-family dwelling, subject to shared utilities, owner occupancy and other conditions21.
Building a home in Putnam County: the steps, in order
- Ask the Building and Planning Department to confirm the parcel's jurisdiction, zoning district, allowed use, setbacks and required approvals229.
- Arrange the soil evaluation and obtain the Putnam County Health Department septic permit before seeking the county construction permit3.
- Submit the Improvement Location Permit application before starting work; premature construction costs twice the current permit fee1. If building for your own use or occupancy, execute the Contractor Listing Exemption if applicable5.
- Secure permission from the authority controlling the road; an entrance on an Indiana state highway requires an INDOT permit23.
- Schedule each required building inspection at least 24 hours ahead and have the septic installer give the Health Department at least 2 business days' notice1119.
- Obtain the required certificate of occupancy before using the completed building24.
What should you check before buying land in Putnam County?
Start with jurisdiction and zoning: the county UDO does not govern every municipality, and district standards change what and where you may build210. Make an offer contingent on septic feasibility because only about 4.2% of Putnam County soils avoid a severe conventional-drain-field limitation20. Putnam County has not confirmed a separate private-well permit rule here, while Indiana warns that some local health departments require approval; ask Environmental Services before drilling7. Check the flood map early because development in a special flood hazard area is subject to county flood-protection standards, including elevation requirements for new or substantially improved residences in Zone A or AE25. Confirm legal road access with the authority that controls the road, and remember that a state-highway connection needs INDOT permission23. If dividing land, county subdivision review may apply26.
Watch-outs
- Starting covered construction before obtaining the required Putnam County permit triggers a fee equal to twice the current permit fee1.
- A stored RV in a covered residential district cannot be occupied for living, sleeping or housekeeping or connected to utilities4.
- The county UDO covers unincorporated land and participating towns, but Greencastle uses city zoning; confirm the parcel's jurisdiction before relying on county standards10.
