Do you need a building permit in Howard County, Indiana?
Yes. Unincorporated Howard County requires a permit before covered construction, alteration, repair or extension work begins when the contract price or estimated cost is more than $1001. The rule reaches buildings, structures, dwellings, plumbing, electrical, heating, ventilation and air-conditioning work, and the Building Commissioner may require detailed plans and specifications1. One- and two-family residential construction is subject to Indiana's statewide residential code, currently based on the 2018 International Residential Code with Indiana amendments15. For a new home, Howard County's Improvement Location Permit process requires a legal description, a scaled plot plan, the owner's signature, proof of an approved building lot, septic or sewer documentation, an MS4 permit and a driveway permit2.
Who is the Howard County building department, and how do you reach it?
Start with the Kokomo-Howard County Plan Commission at 224 N. Main Street, Kokomo, IN 46901; call 765-456-2330 or email [email protected]4. The Plan Commission's official page publishes county planning applications, zoning materials, Improvement Location Permit information and fee information4. Howard County's code refers to a Building Commissioner, but we could not confirm from the county's published materials which office performs construction inspections for one- and two-family homes in unincorporated areas116. Ask the Plan Commission to identify the inspector and inspection schedule for your exact project before work begins4. Separately, call Environmental Health at 765-456-2406 for septic, the Surveyor's Office at 765-456-2217 for the MS4 permit, and the Highway Department at 765-456-2802 for the county-road driveway permit171819.
Does Howard County have zoning?
Howard County has zoning administered through the Kokomo-Howard County Plan Commission in the county planning jurisdiction, especially unincorporated areas57. Standards vary by jurisdiction and zoning district, so City of Kokomo rules should not be applied automatically to county land6. In districts AZ, A1, RS1, RS2 and R1, minimum lot area differs by district and by whether sewer is available; a larger lot may be needed for private sewage disposal20. Front setbacks vary by road classification, side setbacks depend on lot width and rear setbacks vary by district21. The district table generally caps building height at 40 feet, with additional restrictions possible22. Ask the Plan Commission for the parcel's jurisdiction, district and current dimensional table before designing the site4.
How do septic permits work in Howard County?
The Howard County Health Department Environmental Health Office issues permits for on-site sewage systems9. A permit and prior approval are required before an on-site sewage system is built or repaired, and a soil test is needed to size the absorption field8. Howard County's soil data make that early test especially important: only about 0.8% of mapped soils lack severe limitations for a conventional septic drain field23. The permittee must request final inspection and give at least 48 hours, or two working days, of notice before subsurface portions are covered24. When construction or a use change needs residential sewage disposal, Howard County requires the system to be certified approved before granting the certificate of occupancy25. Indiana does not allow drywells or cesspools as on-site sewage treatment26. Contact Environmental Health at 765-456-2406 or [email protected]17.
Can you live in an RV or tiny home on your land in Howard County?
We could not confirm a Howard County rule that generally allows or prohibits living in an RV on a private parcel, so ask the Kokomo-Howard County Plan Commission how the parcel's zoning district treats RV occupancy411. Indiana's campground rule does not settle that private-land question because it governs regulated campgrounds rather than individually deeded lots27. We also could not confirm a county rule aimed specifically at tiny homes11. A tiny home used as a principal dwelling still faces the published district standards: principal dwellings in AZ, A1, RS1 and RS2 have a 720-square-foot minimum ground-floor area12. Ask the Plan Commission whether the proposed unit is a permitted dwelling type in the parcel's district and which setbacks, foundation rules and permits apply4.
Building a home in Howard County: the steps, in order
- Ask the Kokomo-Howard County Plan Commission to confirm the jurisdiction, zoning district and approved-lot status; an unapproved lot may require subdivision approval284.
- Arrange the required soil test and obtain a septic permit from Environmental Health, or secure a City of Kokomo sanitary-sewer tap permit when that connection applies83.
- Obtain the MS4 permit from the County Surveyor's Office and the driveway permit from the County Highway Department for the new-home application3141819.
What should you check before buying land in Howard County?
Confirm zoning, legal-lot status and the current dimensional standards with the Plan Commission before treating a parcel as buildable1130. Test the soil before assuming a conventional septic system will work because only about 0.8% of Howard County's mapped soils lack severe drain-field limitations23. If the property needs a private well, Howard County requires a permit for installation, alteration or major repair, and the application must come from a licensed installer10. Check the flood map too: development in a Special Flood Hazard Area needs an Improvement Location Permit, and work in an identified floodway must be sent to the Indiana Department of Natural Resources for a state permit before the local building permit, subject to exemptions31. A driveway connecting to an INDOT-controlled road needs an INDOT permit rather than only the county-road approval32. Typical local carrying costs include an effective property-tax rate near 0.7% and a median annual tax bill around $1,1103334.
Watch-outs
- For septic questions, use the current Environmental Health contact number, 765-456-2406, rather than relying on an older permit handout17.
- A state agricultural design-release exemption does not erase Howard County zoning, permit or inspection requirements for a farm building351.
- Howard County requires the septic system to be certified approved before a certificate of occupancy is granted when the construction or use change requires residential sewage disposal25.
