Hammond sits directly on the Illinois border in Lake County, in the Chicago metropolitan area, with 75,712 people in the Census Bureau’s 2025 estimate. Building permits and inspections inside the city limits are handled by the Building Division of the Inspections Department, headed by the Building Commissioner, at Hammond City Hall, 5925 Calumet Avenue. Class 1 structures need 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 work inside the City of Hammond limits. Lake County and the neighbouring municipalities are separate authorities.
An Illinois credential does not replace Hammond’s requirements. Every contractor, subcontractor and specialty contractor working in Hammond must be registered with the city. Plumbing work needs a State of Indiana plumbing licence, heating contractors need a Hammond licence obtained by examination, and electrical contractors are licensed by the city’s Electrical Board after an examination. Check credentials before filing.

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
Hammond enforces Indiana's statewide codes with city zoning and development standards layered on. The technical standard matches Lake County's; the fee schedule, submittal process, zoning, inspection scheduling and contractor registration and licensing are local.
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
The Building Division issues permits for construction and remodeling inside the city limits. A conversion to three or more tenants makes the building Class 1, which 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

Hammond requires city registration, and a state or city licence by trade.
Heating exams are monthly; the Electrical Board meets four times a year.
Three or more tenants crosses the line.
No construction on a Class 1 structure may start before it is issued (675 IAC 12-6-3).
It allows work to grade level while review continues, and must be requested with the application (675 IAC 12-6-14).
Every contractor, subcontractor and specialty contractor working in Hammond must be registered.
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 Hammond
The Building Division performs inspections inside the city limits, and its plumbing, heating and cooling, and electrical inspectors inspect the trade work. Ask for the inspection stages 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).
Hammond 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 Hammond Building Division 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.

Frequently asked questions
Can an Illinois-licensed contractor work here?
Not on that credential alone. Hammond requires every contractor working in the city to be registered, plumbing work needs a State of Indiana plumbing licence, and heating and electrical contractors need Hammond licences obtained by examination.
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 →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).
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.
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.
