Porter County sits on Lake Michigan in northwest Indiana, with its county offices in Valparaiso. The Porter County Building Department, headed by a Building Commissioner, at 155 Indiana Avenue, Suite 311, handles permits and inspections for the areas the county serves. Class 1 structures require a state Construction 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 of Porter County served by the county Building Department. Valparaiso, Portage, Chesterton and Burns Harbor run their own building departments; for a parcel in another town, confirm which office issues the permit.

A Class 1 structure owned by the federal government, or on land ceded to exclusive federal jurisdiction, needs no state design release (675 IAC 12-6-4). Near the park, confirm who owns the parcel and which local authority covers it before design.

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 county and municipal departments enforce Indiana's statewide codes, so the technical standard is constant across the county. Fees, submittal processes, zoning frameworks, inspection scheduling and local contractor registration are what differ.
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
In the areas the county serves, building permits are applied for through the county’s online portal. A building with three or more tenants is Class 1 and needs a state design release (IC 22-12-1-4).
Commercial permits
Commercial and industrial buildings used by the public or by employees are Class 1 structures and need a state design release before construction (IC 22-12-1-4; 675 IAC 12-6-3).
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

Federal Class 1 structures need no state design release.
Valparaiso, Portage, Chesterton and Burns Harbor issue their own permits.
The county portal handles applications, review tracking and payment.
Test against the statutory definition, not an impression of the building.
No construction on a Class 1 structure may start before it is issued (675 IAC 12-6-3).
Porter County requires contractors to register in its online portal.
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 Porter County
Book inspections with the department that issued the permit. For a county permit, call 219-465-3473; if you reach the voicemail, leave your name, phone number, jobsite address and permit number. The county retrieves requests through the day and says confirmation calls are not necessary.
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).
Porter 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 Porter County Building Department what it holds for the parcel and establish separately whether a design release exists for the original construction and for any subsequent alteration.

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
What about work near Indiana Dunes National Park?
Check ownership first. A Class 1 structure owned by the federal government, or on land ceded to exclusive federal jurisdiction, needs no state design release (675 IAC 12-6-4). The park has land within 15 cities and towns, so next to it the local permit authority may be a town rather than the county.
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.
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).
Inspections are where schedules slip.
Get a free quote →Can I start before the design release comes back?
Only within a granted partial mechanism. A foundation release allows construction to grade level only; a partial design release allows work to the extent of that scope and no further. Both must be applied for, and neither permits exceeding the released scope.
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).
What does the state design release cost?
Under 675 IAC 12-3-2 it is a $75 filing fee plus a processing fee of at least $75, generally $0.050 per gross square foot for normal occupancy and $0.030 for warehouses, refrigerated storage, hangars and similar uses. Local permit fees are separate.
