Tippecanoe County, in northwest Indiana on the Wabash River, contains Lafayette, the county seat, and West Lafayette, home of Purdue University. Building permits outside those two cities are issued by the Tippecanoe County Building Commission, and Class 1 structures need a state design release before construction.
This guide covers the department and how to reach it, the local conditions that shape a filing here, what permits cost and who may pull them, and how inspections are booked. Rules that apply everywhere in Indiana are summarized in each section, with a link to the full statewide explanation.
This guide covers the areas served by the Tippecanoe County Building Commission: everywhere outside the cities of Lafayette and West Lafayette, which issue their own permits.
Three or more tenants can make a building Class 1. A building occupied by three or more tenants is a Class 1 structure requiring a state design release (IC 22-12-1-4). A one- or two-family dwelling stays Class 2 unless part of it is regularly used as a Class 1 structure (IC 22-12-1-5), so a conversion to multi-tenant occupancy can move a project into state review. Test it against both definitions rather than the building’s appearance.
What requires a building permit in Tippecanoe County?
Class 1 construction needs a state design release unless 675 IAC 12-6-4 exempts it, and local building permits are required as the local ordinance provides.
Permit required
- New residential and commercial construction, additions, alterations and conversions
- Structural and load-bearing work, foundations, decks, porches, ramps and stairs
- Finishing basements and attics, and any change of use or occupancy
- Electrical service changes, panel work, new circuits, solar and EV charging equipment
- Plumbing alterations, repipes, water heaters, backflow and sewer or gas connections
- HVAC installation and change-out, ductwork and venting; roofing, siding, windows, pools, signs and demolition
Typically exempt
- Painting, wallpapering, tiling, carpeting and cabinet installation
- Minor repairs and finish work replacing materials in kind
- Small accessory structures below the local size threshold, where zoning allows
- Portable equipment or temporary work the adopted rules specifically exempt
Which work needs a local building permit is set by local ordinance, and the Class 1 work that needs no state design release is listed in 675 IAC 12-6-4. An exemption from a building permit is not an exemption from zoning, setbacks, floodplain rules, utility approval or a fire authority review. Confirm scope with the department before work starts rather than after.

The county commission and the two cities’ offices all enforce Indiana’s statewide codes. Fees, submittal requirements and contractor rules differ between them.
Before construction starts on a Class 1 structure — one used by the public, by three or more tenants, or by anyone working as another’s employee — Indiana requires a state Construction Design Release, unless the work is exempt under 675 IAC 12-6-4. One- and two-family dwellings and qualifying townhouses are Class 2 and are permitted locally where an ordinance requires it. Indiana enforces the 2014 Indiana Building Code and the 2020 Indiana Residential Code. Class 1 and Class 2 in Indiana

The local building department issues the building permit and inspects the work. On a Class 1 structure the state design release, issued by IDHS or a certified local unit, must come before construction starts; IDHS has 10 business days to respond to a complete application and 20 for a plan review. Plans for Class 1 work over 30,000 cubic feet must be prepared by a registered architect or engineer. The Construction Design Release
Permit types
Residential permits
A residential application needs the application and Advanced Structural Components form, a subcontractor list, the owner’s consent, construction plans, a site plan and one of three energy paths. Decks need a permit, with a post-hole inspection; a portable shed under 120 sq ft does not. The three-tenant threshold decides whether a project needs a state design release.
Commercial permits
Commercial work is charged at $0.35 per square foot with no maximum fee, and Class 1 buildings need a state design release before construction. For any permit, allow up to ten working days after a full submittal.
Since 1 January 2026, a unit that requires permits for one- and two-family work must review plans within 7 business days and offer inspections within 3, and the applicant may use a private reviewer or inspector instead (IC 36-7-2.5). Local permits and the 2026 deadlines
Tippecanoe County permit costs and fees

It decides Class 1 or Class 2.
No construction on a Class 1 structure may start before it is issued (675 IAC 12-6-3).
Septic or sewer, drainage and driveway approvals come before the permit.
It allows work to grade level while review continues, and must be requested with the application (675 IAC 12-6-14).
An agricultural building is outside Class 1 only if it is not used for retail trade, apart from a farm-produce stand open eight months or less a year (IC 22-12-1-4).
The permit is not issued until each listed contractor’s License & Permit Bond is on file.
A design release expires if work has not started within one year, with one extension of up to 180 days; the local permit runs on its own clock, so track both on Class 1 work. How long a design release lasts
Inspections in Tippecanoe County
Schedule inspections with the office that issued the permit; the county commission is at 765-423-9225. Deck and pole-barn post holes must be inspected before the posts are set. The department sets the other inspection stages; ask for its list when the permit is issued.
Do not cover work before the required inspection has been approved. On Class 1 work the design release must be posted on site and a complete set of the released plans kept there until occupancy (675 IAC 12-6-19).
Tippecanoe County permit search and official resources
Permit records for one project can sit in two places. The local department holds the building permit, the inspection history and the certificate of occupancy; IDHS holds the Construction Design Release file for Class 1 work, including releases issued by certified local units (IC 22-15-3-1). If you are buying, refinancing or renovating a commercial property, ask the Tippecanoe County Building Commission what it holds for the parcel and establish separately whether a design release exists for the original construction and for any subsequent alteration.

Frequently asked questions
Does student housing need a state design release?
A building occupied by three or more tenants is a Class 1 structure (IC 22-12-1-4) and needs a state design release before construction. A one- or two-family dwelling stays Class 2 unless part of it is regularly used as a Class 1 structure, so a conversion to multi-tenant occupancy can move a project from Class 2 into state review.
Which areas does the county commission serve?
Everywhere outside the cities of Lafayette and West Lafayette, including the towns of Battle Ground, Clarks Hill and Dayton. In Shadeland the town reviews zoning, drainage and erosion control first, and the county handles the rest of the permit process under an interlocal agreement.
Is my project a Class 1 or a Class 2 structure?
Test it against IC 22-12-1-4. A Class 1 structure is one occupied or used in any part by the public, by three or more tenants, or by one or more persons acting as the employees of another. Class 2 covers one- and two-family dwellings and qualifying townhouses. A building used by even one person working as another’s employee is Class 1.
Inspections are where schedules slip.
Get a free quote →What is a Construction Design Release?
A state approval that must be issued before construction may be done on a Class 1 structure (675 IAC 12-6-3). It is issued by IDHS or by a city, town or county certified to issue releases (IC 22-15-3-1), and building a Class 1 structure without one is a Class C infraction (IC 22-15-3-7).
Do I need an Indiana-licensed architect or engineer?
It depends on volume, not cost. Under 675 IAC 12-6-9 a design professional is required for Class 1 work needing a design release, except for structures of 30,000 or fewer cubic feet, additions adding 30,000 or fewer cubic feet, alterations not affecting structural safety, and certain sprinkler work.
Which contractor licences does Indiana issue?
The state licenses plumbing contractors and journeyman plumbers (IC 25-28.5). It issues no electrical, HVAC or general contractor licence; any registration or licensing for those trades is set by the city, town or county, which may also require licensed plumbing contractors to register locally (IC 25-28.5-1-33).
