Lafayette, on the Wabash River in northwest Indiana, is the seat of Tippecanoe County. Building permits inside the city limits are issued by the City Engineer’s Office (Engineering & Public Works, 20 North 6th Street). The Tippecanoe County Building Commission, at 20 North 3rd Street, issues permits outside the cities.
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 work inside the City of Lafayette limits. West Lafayette has its own City Engineer’s Office, and the Tippecanoe County Building Commission covers the areas outside the cities.
The city issues every building permit inside its limits. The City Engineer’s Office issues all building permits for construction in the Lafayette city limits, and it issues permits only for properties inside city limits, with few exceptions. The Tippecanoe County Building Commission, also in Lafayette at 20 North 3rd Street, covers the areas outside the cities. Check the city’s GIS and zoning maps to confirm the parcel is inside city limits before assembling a package.

Get a free quote →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.
Which code edition applies
The city and the county commission both enforce Indiana’s statewide codes. Each sets its own fees, submittal requirements and contractor bonding, and the city also licenses electrical contractors.
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

Get a free quote →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
On residential projects a homeowner may do all the work personally, provided they submit a copy of their homeowner’s insurance, live or plan to live at the property, and use a state-licensed plumber for any plumbing. Residential reviews take up to seven days from a complete submittal. The three-tenant threshold decides whether a project needs a state design release.
Commercial permits
Commercial reviews take up to ten business days. The clock starts only when all required documents are submitted and all administrative requirements are met. Class 1 buildings also need a state design release before construction.
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
Lafayette permit costs and fees

| Fee component | How it works |
|---|---|
| State design release | Class 1 only: $75 filing fee plus a processing fee, generally $0.050 or $0.030 per gross sq ft by occupancy category (675 IAC 12-3-2) |
| Local building permit | $0.15 per sq ft ($200 minimum) for single-family and duplex work; $0.25 per sq ft ($250 minimum, $10,000 maximum) for multifamily, commercial and industrial work |

| Contractor bonds | $5,000 for general contractors; $1,000 for plumbers and for electrical-only permits |

Rather not deal with the building department?
Get a free quote →How to apply for a Lafayette building permit
The city issues permits only inside its limits, with few exceptions.
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).
The review clock starts only when every required document is in.
It allows work to grade level while review continues, and must be requested with the application (675 IAC 12-6-14).
Electricians need a City of Lafayette licence; general contractors and plumbers post bonds.
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 Lafayette
Schedule inspections with the authority that issued the permit; inside the city that is the City Engineer’s Office, 765-807-1050. The department sets the inspection stages; ask for its list when the permit is issued.
On a portfolio spanning city and county parcels, keep records attributed to the issuing authority: the city and the county commission keep separate permit records.
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).
Lafayette 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 City Engineer’s Office what it holds for the parcel and establish separately whether a design release exists for the original construction and for any subsequent alteration.
Confirm the classification first, then the process. Whether a structure is Class 1 or Class 2 decides whether a state Construction Design Release is required, whether a design professional must be engaged, and which fees apply. Test it against IC 22-12-1-4 rather than against an impression of the building, and confirm current state and local requirements, fees and review turnaround for your filing date.

Frequently asked questions
Do I file with the city or the county?
Inside the Lafayette city limits, file with the City Engineer’s Office at 20 North 6th Street (765-807-1050). Outside the cities, the Tippecanoe County Building Commission at 20 North 3rd Street (765-423-9225) issues permits, and West Lafayette has its own City Engineer’s Office.
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 test each conversion against both definitions.
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).
