Do you need a building permit in Howard County, Indiana?
Unincorporated Howard County requires a building permit before covered construction, alteration, repair or extension work costing more than $100 begins; the requirement includes building systems such as plumbing, electrical and HVAC work1. The Building Commissioner may require detailed plans and specifications1. Howard County has adopted construction codes for unincorporated areas, but the county code compilation references older editions15. Residential construction and accessory structures must comply with the 2020 Indiana Residential Code, based on the 2018 International Residential Code with Indiana amendments16. New-home Improvement Location Permit applications require approved-lot verification, a legal description, scaled plot plan, owner signature, septic or sewer documentation, an MS4 permit and a driveway permit3.
Who issues building permits in Howard County, and how do you reach them?
Start with the Kokomo-Howard County Plan Commission at 224 N. Main Street, Kokomo, IN 46901; call 765-456-2330 or email khcpc@cityofkokomo.org4. Howard County's code establishes a Department of Buildings and Building Commissioner to administer and enforce county construction codes17. We could not confirm the current residential inspection office or schedule for unincorporated Howard County; ask the Plan Commission which office inspects your project184. Inside Kokomo, the City Civil Engineer issues general building permits for covered work; Greentown also issues its own building permits1920. Septic permitting remains with Howard County Environmental Health throughout the county5. Call Environmental Health at 765-456-2406 for septic, the Surveyor's Office at 765-456-2217 for the new-home MS4 permit, and the Highway Department at 765-456-2802 for the new-home driveway permit212223.
Does Howard County have zoning?
Howard County zoning applies outside the legally established planning jurisdictions of cities and towns, with uses and development standards determined by the parcel's district224. Kokomo and Greentown have their own zoning; Howard County Environmental Health still handles septic permitting679. For subdivisions under county jurisdiction, lots must be at least 60 feet wide at the building setback line and at least 7,200 square feet, but district and health requirements can demand more land25. Subdivision lots without community water and sanitary sewer must meet Board of Health lot-width and area requirements; lots with those services must meet the applicable zoning district's single-family standards25. Subdivision building lines follow the zoning code, rather than a single countywide setback26. The published district table varies front setbacks by road type, side setbacks by lot width and rear setbacks by district27. In AZ, A1, RS1 and RS2, the table limits combined principal and accessory building coverage to 30 percent and principal building height to 40 feet, with additional height restrictions possible2829. Ask the Plan Commission for current district dimensions before designing the site4.
How do septic permits work in Howard County?
The Howard County Health Department Environmental Health Office issues local septic permits9. Prior approval and a permit are required before an on-site sewage system is built or repaired, and a soil test is required 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 field30. The permittee must request final inspection and give at least 48 hours, or two working days, of notice before subsurface portions are covered; the system cannot enter service before Health Officer acceptance3132. Howard County off-grid sanitation using an on-site sewage system still requires soil testing, plan approval, permitting, inspection and final acceptance; drywells and cesspools cannot be used as sewage treatment3334. A homeowner may install a system on their own property after passing the required regulations exam, but the exemption covers installer license fees and insurance rather than the septic permit itself13. Contact Environmental Health at 765-456-2406 or environmental@howardcountyin.gov21.
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 lots35. 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.
How do you apply for a new-home building permit in Howard County?
Confirm the parcel's jurisdiction, zoning district and approved-lot status with the Plan Commission; unapproved lots may require subdivision approval, and subdivision plats or replats cannot be recorded before written Commission approval3364.
For a new home, obtain either a Howard County septic-system permit or a City of Kokomo sanitary-sewer tap permit, plus the Surveyor's MS4 permit and Highway Department driveway permit37382223. The checklist does not establish a universal water or sewer hookup requirement for every parcel39.
Submit the owner-signed Improvement Location Permit application with a complete legal description and scaled plot plan showing existing and proposed buildings, rights-of-way, utility easements and drainage easements40. The published fee is $1 per $1,000 of improvement cost, with a $15 minimum and $1,000 maximum; an after-the-fact permit adds $10 per $1,0004142. The fee sheet is dated 2008, so confirm the current charge with the Plan Commission before applying434.
What should you check before buying land in Howard County?
Confirm zoning, legal-lot status and current dimensional standards with the Plan Commission before treating a parcel as buildable4445. 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 limitations30. 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: Howard County requires an Improvement Location Permit before development in a special flood hazard area, and floodway work requires state authorization before the local building permit46. Howard County floodway-fringe structures must meet Flood Protection Grade requirements, and the zoning administrator inspects special-flood-hazard-area construction before, during and after construction47. A driveway onto an INDOT-controlled roadway needs an INDOT permit48. Typical local carrying costs include an effective property-tax rate near 0.7% and a median annual tax bill around $1,1104950.

- Share of soils USDA rates "not limited" for a conventional septic drain field (SSURGO). A strict rating: the median county is about 6% and a tenth of counties are 0%, so a low figure means most lots need a site evaluation or an engineered system, not that septic is impossible.
