Do you need a building permit in Cass County, Indiana?
Yes. Cass County requires Improvement Location Permits and associated building permits for covered construction, reconstruction, moving, alteration, enlargement, occupancy and changes of use1. Driveway-cut and septic approvals, when applicable, must be submitted before the county processes the Improvement Location Permit and building permit1. Construction is inspected at the footer, rough-in and final stages; footer approval comes before pouring, rough-in approval before insulation or coverings, and the final inspection before occupancy9. Demolition, footer, rough-in and final inspections require at least 24 hours' notice9. Agriculture uses and structures are exempt from the Improvement Location Permit unless they are confined feeding operations, though other rules can still apply4. Indiana's state exemption for agricultural buildings used only for farming on the land where they stand does not waive local inspection, zoning or other requirements11. Building and fire-safety codes are set by the state commission, including the Indiana Residential Code for homes, and counties add only administrative rules such as permits and inspection schedules812.
Who issues Cass County building permits, and how do you reach them?
The Cass County Planning Department is the first stop for building and demolition permits, zoning and floodplain status, and subdivision applications13. The office is in the Cass County Government Building at 200 Court Park, Room 306, Logansport, IN 46947; call (574) 753-7775 or email arin.shaver@casscountyin.gov13. The published county process may require site plans, septic approval, driveway or INDOT permits, and stormwater materials before permit processing14. Cass County's published fee schedule lists a $100 single-family base fee and a $10 residential Improvement Location Permit, but a later county ordinance amended building and zoning fees, so confirm the current total with Planning before filing1516. A permit becomes void after one year if the work has not been substantially completed1.
Does Cass County, Indiana have zoning?
Yes. Cass County zoning applies in unincorporated areas, while land under a city or town plan commission may follow that municipality's rules2. The county separately publishes zoning materials for Cass County and Walton, so confirm which jurisdiction controls the parcel before relying on a district label17. Minimum lot area, lot width, front, side and rear yards, and maximum lot coverage vary by zoning district31819. In a recorded subdivision, the plat's setback lines set the front-yard dimension unless the district's rule is less restrictive20. The Gateway District also requires at least 10% green space and caps building height at 199 feet; neither figure is a countywide standard1921. Subdivision review addresses utilities, access, drainage, farmland, lot design and sewage feasibility, and a municipal subdivision ordinance may apply inside an incorporated jurisdiction22. A countywide minimum house size, tiny-home rule and accessory-dwelling rule could not be confirmed; ask Planning for the parcel-specific answer.
How do septic permits work in Cass County?
The Cass County Health Department handles onsite sewage permits and review5. A written permit signed by the health officer is required before construction or installation, and an onsite evaluation comes first23. Start by obtaining its application packet and hiring a soil scientist for the soil report; submit the completed application, report and $100 permit fee to the Health Department5. After installation, the installer must allow two working days for the county's onsite inspection, and final approval requires code-compliant completion5. Call (574) 753-7760 or visit 1616 Smith Street in Logansport24. Only about 11.1% of Cass County soils avoid severe limitations for a conventional drain field, so resolve septic feasibility before fixing the house location10. Where sanitary sewer is available within a reasonable distance, onsite disposal is prohibited and sewer connection is required25. A dwelling that cannot connect to sewer needs a compliant septic tank and functioning soil-absorption system; drywells and cesspools are not allowed26. If an existing system fails, the health officer may require connection to a sanitary sewer within 300 feet of the property line when the cost stays within 150 percent of a new onsite system27.
Can you live in an RV or tiny home on land in Cass County?
Cass County prohibits using a major recreational vehicle for living or housekeeping on a residential lot or at a location not approved for that use6. An RV may be parked on a residential lot for up to 48 hours while loading or unloading, but that allowance does not authorize occupancy6. Temporary group camps are a separate use allowed in listed districts for one week per six months per site, with a permit and controls on lights and noise28. Ask the Planning Department whether a proposed location and use qualify. In the county-regulated floodplain, a manufactured home in place more than 180 days must sit on a permanent foundation with its lowest floor at or above the flood protection grade29. Cass County does not provide a confirmed countywide tiny-home occupancy or minimum-dwelling-size answer in the available rules; a tiny home still needs parcel-specific zoning and permit review21. No general owner-builder exemption was confirmed, so an owner doing the work should ask Planning who may pull permits and how inspections are scheduled3013.
Building a home in Cass County: what are the steps?
Handle the approvals in dependency order:
- Ask the Planning Department to confirm the governing jurisdiction, zoning district, permitted use, minimum lot size and setbacks2318.
- Ask whether sewer is available; if not, obtain the Health Department packet, soil report and onsite sewage permit255.
- Secure the driveway approval from the road owner before permit processing; state-highway access goes through INDOT's permit system3132.
- Submit the plans, supporting approvals, fee and building-permit application to Planning1413.
- Resolve floodplain review and applicable state or federal permits before construction if the site is mapped in a floodplain33.
- Schedule footer, rough-in and final inspections with at least 24 hours' notice, then obtain the Certificate of Occupancy before moving in934.
What should you check before buying land in Cass County?
Verify the governing zoning authority, district, permitted use, minimum lot area, setbacks, lot coverage and overlay before treating advertised acreage as a usable homesite231819. Make the purchase contingent on septic feasibility when onsite sewage is needed: only about 11.1% of county soils avoid severe conventional drain-field limitations10. Ask the Health Department whether Cass County requires a private-well permit, because the available statewide guidance says some local departments do but does not identify Cass County3524. Confirm legal access and driveway approval with the road owner before closing; county permit processing requires applicable driveway-cut documents, while INDOT controls state-highway connections3132. Check mapped floodplain status with Planning because floodplain development can require local, state and federal approvals3313.
Watch-outs
- Cass County exempts qualifying agriculture uses and structures from the Improvement Location Permit, except confined feeding operations, but parcel-specific zoning and other approvals can still matter42.
- Only about 11.1% of Cass County soils avoid severe limitations for a conventional drain field, so establish septic feasibility before fixing the house location10.
- Do not plan to live in an RV on a residential lot while building: Cass County prohibits living or housekeeping in an RV there unless the location is approved for that use6.
- The published fee schedule lists older amounts, while a later ordinance amended building and zoning fees; confirm the current charge with Planning before filing16.
