Do you need a building permit in Tippecanoe County, Indiana?
Yes, in most of the county. The Tippecanoe County Building Commission issues building permits for construction, fills, demolition and electrical work everywhere except inside the City of Lafayette and West Lafayette, which have their own permit channels12. Septic permits stay with the county Health Department in those cities too3. An application must include building and site plans; review may take up to 10 days, and a permit is valid for 2 years if work starts within the first year4. The 2020 Indiana Residential Code is currently in effect for applicable residential construction in Tippecanoe County12. County inspections require 24 hours' notice13. We could not confirm a general owner-builder or agricultural exemption, so ask the Building Commission before assuming either applies.
Who issues building permits in Tippecanoe County, and how do you reach them?
The Tippecanoe County Building Commission office is at 20 North 3rd Street, Lafayette, IN 4790114. Call 765-423-9225 or email buildingpermits@tippecanoe.in.gov during business hours of 8:00 AM to 4:30 PM14. Bring a check or exact cash when applying in person; permit payments are accepted until 3:30 p.m. daily13. For fees effective April 20, 2026, listed single-family residential work costs $0.25 per square foot with a $75 minimum and a $20 filing fee15.
Does Tippecanoe County have zoning?
Yes, in unincorporated Tippecanoe County, where the Area Plan Commission investigates possible violations of the Unified Zoning Ordinance2. Lafayette and West Lafayette run separate city channels, and rules vary by jurisdiction, so confirm which authority governs the parcel5. Tippecanoe County has a Unified Zoning Ordinance and published zoning maps; the FP district marks the adopted floodplain1617. Outside city and town limits, one accessory dwelling unit may be allowed on a single-family property zoned A, AA, AW or RE18. A tiny home that qualifies as an ADU must be at least 400 square feet10. A detached ADU must meet applicable setbacks and sit at least 6 feet from the primary home, but the parcel's lot-line setback still depends on its district19. Minimum lot area is district-specific, not one countywide figure20. Ask the Area Plan Commission at 765-423-9242 to confirm the parcel's authority, district and dimensional rules21.
How do septic permits work in Tippecanoe County?
The Tippecanoe County Health Department requires a permit before construction begins on any new or repaired residential or commercial septic system anywhere in the county, including Lafayette and West Lafayette67. County staff inspect the installation when it is complete, and the county also offers existing-system inspections for real-estate transactions22. Only about 6% of Tippecanoe County soils rate free of severe limits for a conventional drain field, so settle the site evaluation and system design early8. Indiana's on-site sewage rule is administered locally, and drywells and cesspools are not allowed as substitutes2324. A temporary holding tank requires written state approval and is generally limited to 1 year unless satisfactory operation is documented24.
Can you live in an RV or tiny home on your land in Tippecanoe County?
We could not confirm a rule allowing full-time RV occupancy on an ordinary private lot in Tippecanoe County; the one RV-occupancy example we found is an RV park or campground in an A agricultural district, which needs a special exception under the Unified Zoning Ordinance25. The county park rule allows camping only at Ross Camp campground, but that rule does not answer private-property camping11. Indiana's campground rule likewise governs regulated campgrounds rather than residential use on an individually deeded lot26. A tiny home can qualify as an accessory dwelling in a rural zone outside city and town limits when it meets the ADU conditions: one ADU per parcel, one family, the owner living in the principal dwelling or the ADU, and a minimum area of 400 square feet271018. An ADU cannot be used as a transient guest house or short-term rental28. A detached ADU must be at least 6 feet from the primary home and also meet the applicable setbacks19. Before placing or occupying an RV or tiny home, ask the Area Plan Commission at 765-423-9242 for a parcel-specific answer21.
How do you build a home in Tippecanoe County, step by step?
- Confirm the parcel's zoning authority, district and dimensional rules with the Area Plan Commission at 765-423-9242521.
- If the home needs septic, obtain the county Health Department permit before construction begins6.
- If fill or other development lies in a floodway, obtain the Indiana DNR permit before the local permit; the county fill review also involves the Area Plan Commission, Highway Department and Surveyor29.
- Submit building and site plans to the Building Commission at 765-423-9225; allow up to 10 days for review414.
- Ask the Highway Department about a Residential Drive Permit before creating an entrance on a county road9.
- Give the Building Commission 24 hours' notice for inspections, start work within the first year, and finish within the permit's 2-year validity period13.
What should you check before buying land in Tippecanoe County?
Ask the Area Plan Commission which zoning authority and mapped district govern the parcel, and ask the Building Commission whether the site is in county jurisdiction or one of the cities with a separate permit channel5174. Get a septic evaluation before counting on a conventional drain field: only about 6% of county soils rate free of severe limits8. If the parcel will be divided, Tippecanoe County subdivision standards require professionally prepared, certified as-built plans before final inspection, including county-right-of-way streets, drainage, water and sanitary improvements; Highway Department approval comes before street acceptance30. For a floodway parcel, an Indiana DNR permit must come before the local permit for fill work29. Farmland here runs about $8,601 an acre and typical homes around $304,284, with an effective property tax rate near 0.6% and a median tax bill close to $1,355 a year31323334. A private driveway or field-access permit on a state highway costs $553536.
Watch-outs
- Private-property RV occupancy could not be confirmed; tiny homes may qualify as ADUs, but ask the Area Plan Commission at 765-423-9242 to verify the parcel and proposal before buying or placing a unit1021.
- Only about 6% of Tippecanoe County's soils are rated free of severe limits for a conventional septic drain field, so budget for a site evaluation and possibly an engineered system before you count on a standard septic layout8.
- Lafayette and West Lafayette issue their own building permits, so a parcel inside either city is outside the county Building Commission's area; septic permits still come from the county Health Department13.

- 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.
