In St. Joseph County — a north-central Indiana county on the Michigan line, home to South Bend (county seat: South Bend) — the actual building permit is issued locally; Class 1 structures must also obtain a state Construction Design Release from the Indiana Department of Homeland Security before that permit issues.
This guide covers what requires a permit, how Class 1 and Class 2 structures differ, the state Construction Design Release, fees, trade permits, and inspections — so your St. Joseph County project stays on track.
St. Joseph County — a north-central Indiana county on the Michigan line, home to South Bend, seat South Bend. The building permit itself is issued locally: the St. Joseph County building department for the areas it serves, and incorporated cities and towns through their own departments. Class 1 structures must also obtain a state Construction Design Release from IDHS before the local permit issues; Class 2 one- and two-family dwellings are permitted locally. The county building department serves unincorporated areas; South Bend and Mishawaka run their own.
Indiana administers its building codes through the Indiana Department of Homeland Security (IDHS), Division of Fire and Building Safety, under codes adopted by the Fire Prevention and Building Safety Commission (FPBSC). Indiana’s defining feature is the split between Class 1 and Class 2 structures. Class 1 structures — commercial, industrial, and public buildings, plus residential buildings with three or more dwelling units (IC 22-12-1-4) — require a Construction Design Release (CDR) from IDHS state Plan Review before a local building permit can be issued (675 IAC 12-6-3). The CDR application starts an automatic 10-business-day clock, after which IDHS responds with a design release, a notice of incomplete filing, or a notice that the project was selected for detailed review; applications are filed electronically. Class 2 structures — one- and two-family dwellings — do not require a state CDR and are permitted and inspected locally. The local building department issues the actual building permit in both cases; where no approved local building official exists, the State Building Commissioner / IDHS provides Class 1 inspection. Indiana is a home-rule state — local jurisdictions may adopt newer code editions or amendments above the statewide minimum, so the exact edition can vary by jurisdiction.
What requires a building permit in St. Joseph County?
Under Indiana’s FPBSC codes, a permit is required for most construction activities — and Class 1 structures additionally need a state design release:
Permit required
- New residential and commercial construction, additions, and conversions
- Structural and load-bearing alterations
- Reroofing, siding, windows, doors, decks, and porches (per local rules)
- Electrical service changes and most wiring work
- HVAC installations, changeouts, and ductwork
- Plumbing alterations, repipes, and water heaters
- Detached garages, accessory structures, fences, pools, and signs
- Any Class 1 structure — which also needs a state Construction Design Release
Ordinary maintenance / minor work
- Painting, wallpapering, tiling, carpeting, and cabinet installation
- Minor repairs and finish work that replace materials in kind
- Small accessory structures below the local size threshold (verify locally)
- Routine maintenance that does not alter structure, egress, or systems
Thresholds vary by jurisdiction, and some rural areas have limited local plan review for Class 2 dwellings. When unsure, confirm with the local building department before starting.
Get the permit — and the design release — before starting work. Building a Class 1 structure without a Construction Design Release, or any project without a local permit, can result in penalties, stop-work orders, and mandatory correction.
Who handles permitting in St. Joseph County?
In St. Joseph County, the county building department issues building permits and inspects work in the county’s unincorporated areas; incorporated cities and towns run their own departments. Class 2 one- and two-family dwellings are permitted locally; Class 1 structures need a state Construction Design Release from IDHS before the local permit issues. The county building department serves unincorporated areas; South Bend and Mishawaka run their own. Confirm which department has authority over a specific address before you file.
| Detail | Information |
|---|---|
| Permits issued by | the St. Joseph County building department (unincorporated areas) — incorporated cities run their own |
| County seat | South Bend |
| State release (Class 1) | Construction Design Release from IDHS — required before the permit issues |
| Apply | Local building permit application — file with the department that has authority over the address |
| Licensing | State plumbing license (IPLA); local electrical, HVAC & contractor registration |
| Code | Indiana FPBSC — 2021 IBC (Class 1) / 2018 IRC (Class 2); state-licensed plumbers |
Two tracks, one project. File the local building permit application with construction documents and, for any Class 1 structure, the IDHS Construction Design Release (you may file both in parallel, but the release is required before the local permit issues). Confirm your state plumbing license and local electrical/HVAC/contractor registrations, pay fees, and post the permit on site before work begins.

St. Joseph County trade permits
Electrical, plumbing, and mechanical work each needs its own permit and an appropriately licensed contractor — note Indiana’s split between state and local licensing.
Electrical permits
Required for service installations, panel upgrades, solar PV, EV chargers, and most wiring alterations. Indiana has no statewide electrician license — electrical contractors are licensed locally (for example, by the Indianapolis Department of Business and Neighborhood Services). The NEC edition is set by the FPBSC as a statewide minimum, but local departments may adopt a newer edition (Indianapolis uses the 2020 NEC), so confirm the applicable edition with the local building department.
Plumbing & gas permits
Required for new plumbing, repipes, water-heater changeouts, fixtures, backflow, and sewer/gas connections. Plumbing is the one trade Indiana licenses at the state level — the contractor must hold an Indiana Plumbing Contractor license (Indiana Plumbing Commission / IPLA). Work is inspected against the Indiana Plumbing Code (675 IAC 16).
Mechanical (HVAC) permits
Required for HVAC installations, changeouts, ductwork, and venting, and inspected against the Indiana Mechanical Code. HVAC contractors are licensed locally (no statewide HVAC license); confirm registration with the jurisdiction issuing the permit.
Fire protection & specialty
Sprinkler, standpipe, and fire-alarm work on Class 1 structures is reviewed as part of the Construction Design Release and coordinated with the State Fire Marshal; fire-suppression contractors are licensed under IC 22-11-14. Pools, demolition, signs, and elevators follow separate tracks.
Verify contractor licensing — it is unusually split in Indiana. Plumbers are the one statewide-licensed construction trade: the Indiana Plumbing Commission (administered through the Indiana Professional Licensing Agency, IPLA) issues Plumbing Contractor and Journeyman Plumber licenses, and a state plumbing license is required to perform plumbing work statewide. By contrast, Indiana has no statewide license for electricians, HVAC contractors, or general contractors — those are regulated locally, so a contractor licensed in one city may need a separate registration in the next (for example, Indianapolis issues electrical-contractor licenses through BNS). Confirm the state plumbing license and any local electrical, HVAC, and contractor registrations for the specific jurisdiction before signing a contract.
How to get a building permit in St. Joseph County
Confirm which department has authority
Identify whether your address is in the county’s unincorporated area or inside an incorporated city or town, and contact the St. Joseph County building department (or that city’s department) to confirm who issues the permit.
Classify the structure (Class 1 vs Class 2)
Determine whether the project is Class 1 (commercial, industrial, public, or 3+ dwelling units) or Class 2 (one- or two-family). The classification decides whether a state Construction Design Release is required.
Obtain a Construction Design Release (Class 1)
For Class 1 structures, file the CDR application electronically with IDHS state Plan Review. The filing starts a 10-business-day clock; the release must be in hand before the local permit issues. Class 2 dwellings skip this step.
Prepare your local application package
Assemble the local building permit application with construction documents — sealed by an Indiana-licensed design professional where required — plus scope, valuation, zoning approval, your state plumbing license, and local trade registrations.
Submit & pay fees
File with the department that has authority over the property, provide the IDHS design release (or exemption) for Class 1 work, and pay the local permit and plan-review fees.
Inspections & Certificate of Occupancy
Schedule inspections (foundation, framing, rough-in MEP, energy, final) with the issuing department. A Certificate of Occupancy is required before legal occupancy of new or changed-use space.
Inspections in St. Joseph County
Schedule inspections through whichever department issued your permit. Standard checkpoints include foundation, framing, rough-in electrical/plumbing/mechanical, insulation/energy, and final. A Certificate of Occupancy is required before legal occupancy of new or changed-use space.
Address correction notices before requesting a re-inspection; a final inspection and Certificate of Occupancy are required before legal occupancy or use.
