Roads & Utilities
ROADS & TRANSPORTATION
Roads: I-65, I-80/94, and US-30 serve Crown Point, the county seat, in the Chicago metropolitan area. Lake County was organized in 1837; the county seat contest among Lake Court House (Crown Point), Liverpool, and West Point (Cedar Lake) was settled in 1840 in favor of Lake Court House after an earlier 1839 selection of Liverpool proved locally unpopular.
Notes: Lake County is home to Indiana’s historic steel industry, anchored by Gary, founded by U.S. Steel in 1906 and named for the company’s board chairman, Elbert H. Gary.
Business & Permits
BUILDING & PERMITS
Office: Lake County Courthouse (“The Grand Old Lady”) – Public Square, Crown Point, IN (built 1878-1880, Romanesque/Georgian, architect John C. Cochrane of Chicago; National Register of Historic Places since 1973; now houses the Lake County Historical Society Museum).
Notes: The historic Lake County Sheriff’s House and Jail (226/232 S. Main Street, Crown Point, built 1882, Second Empire; National Register of Historic Places since 1989) was the site of one of the most famous jailbreaks in American criminal history: on March 3, 1934, gangster John Dillinger – held there after his January 1934 arrest for a bank robbery that killed a detective – escaped using either a carved wooden gun or a smuggled real weapon (accounts vary), locking up 14 jailers before fleeing in the sheriff’s own car. Sheriff Lillian Holley, who had taken office after her husband Sheriff Roy Holley was shot and killed, was unfairly mocked in the press for the escape, though investigations found the fault lay with the jail warden and his officers. The sheriff’s house served as an actual residence until 1958 and jail until 1974, and is preserved today by the Old Sheriff’s House Foundation, open to the public.

About Lake County
Lake County is Indiana’s northwesternmost county – geographically, culturally, and economically part of the Chicago metropolitan area rather than the Indiana heartland. The county’s northern border runs along the southern shoreline of Lake Michigan, which also forms its northern boundary. Lake County’s identity was forged in steel: Gary – incorporated in 1906 and named for U.S. Steel chairman Elbert Gary – was built almost overnight as one of the largest planned industrial cities in American history, and at its mid-century peak was one of the most productive steel-producing cities in the world. The collapse of the American steel industry from the 1970s through the 1990s hit Gary harder than almost any other city, triggering decades of depopulation, deindustrialization, and fiscal stress that have made Gary’s trajectory one of the most-studied examples of post-industrial urban decline in the United States. Today Gary is slowly rebuilding around its architecture (the city retains extraordinary early 20th-century buildings), arts, and proximity to Chicago and the Dunes.
Hammond is Lake County’s largest city, a diverse working-class community on the Illinois border with significant Latino and African American populations. Crown Point (the county seat) and the southern suburban communities of Merrillville, Schererville, Munster, Dyer, and St. John have grown substantially as residents seek Lake County’s lower taxes and housing costs while maintaining access to Chicago’s job market. Indiana Dunes National Park – the newest national park in the continental US (designated 2019, though the state park has existed since 1925) – stretches along 15 miles of Lake Michigan shoreline in Lake County, offering one of the most unusual landscapes in the Midwest: towering sand dunes next to an industrial shoreline.
County government is a three-member Board of County Commissioners with a County Council, and separately elected offices for the Auditor, Assessor, Circuit Clerk, Coroner, Recorder, Sheriff, Treasurer, and Prosecutor.

Indiana assesses property at 100% of market value-in-use – the value a property would have if it were to continue in its current use. The Lake County Assessor (2293 N. Main Street, Building A, Crown Point, 219-755-3100) oversees assessment for the county, with township assessors operating at the local level.
The Indiana appeal process – Form 130:
If you disagree with your property’s assessed value, file Form 130 – Taxpayer’s Notice to Initiate an Appeal with your local assessing official. The appeal deadline is within 45 days of the date the tax bill (Form 11) is mailed – typically resulting in a June 15 deadline for most Lake County properties (if Form 11 is mailed before May 1; if mailed after April 30, the deadline shifts to 45 days from mailing).
The appeal proceeds through three levels:
Level 1 – Informal conference with assessor: The assessor reviews your property record card for errors (wrong square footage, incorrect features, etc.) and compares your assessment to market data. If resolved, both parties sign a Form 134 Joint Agreement.
Level 2 – Property Tax Assessment Board of Appeals (PTABOA): If unresolved at the informal level, the PTABOA – a county board with certified assessor-appraisers – holds a formal hearing. You receive at least 30 days’ notice of the hearing date. Bring comparable sales data, an independent appraisal, or evidence of property condition issues. The PTABOA issues a Form 115 Assessment of Determination.
Level 3 – Indiana Board of Tax Review (IBTR): If unsatisfied with the PTABOA, file Form 131 with the IBTR within 45 days of the PTABOA notice of determination. A copy must also be filed with the County Assessor. After the IBTR, appeal to the Indiana Tax Court is available.
Senior deductions: Indiana offers several property tax deductions for qualifying senior homeowners – including the Over 65 Deduction (age 65+, income and assessed value limits) and the Blind or Disabled deduction. Apply through the Lake County Auditor’s office. Indiana also offers a Homestead Deduction for owner-occupied primary residences.
Indiana has no state estate tax (phased out in 2013) and no state inheritance tax (phased out in 2013). Property taxes are due in two installments: typically May 10 and November 10.
OWNWELL CTA: Lake County’s June 15 appeal deadline (Form 130 within 45 days of Form 11 mailing) is firm. Check your property record card for errors first – objective corrections can be resolved quickly at the assessor level. PTABOA hearings require evidence, not just assertions. Ownwell manages the full process with no upfront cost.

Steel industry legacy and estate planning: Lake County’s multi-generational steelworker families often have union pension assets (United Steelworkers pension plans), defined benefit retirement income, and in many cases complex family situations related to industrial disability or occupational disease. Several retired steelworkers have claims against defunct companies – understanding how such claims interact with estate assets is a local specialty.
Senior Services: The Lake County Council on Aging (219-762-4636) and the Area Agency on Aging of Lake and Porter Counties coordinate senior centers, home-delivered meals, transportation, SHIP Medicare counseling (Indiana SHIP), caregiver support, Adult Protective Services, and connections to Indiana Medicaid long-term care programs.

Probate & Estate
Losing someone and having to deal with courts and paperwork at the same time is hard. This section won’t make that easier, but it should tell you what to expect, what it costs, and where to go – so at least you’re not walking in blind.
Where to go
Lake County Circuit Court (31st Judicial Circuit) 2293 North Main Street, Crown Point, IN 46307 (219) 755-3460
Lake County was established February 16, 1837, named for Lake Michigan. It is Indiana’s 2nd-most-populous county, part of the Chicago metropolitan area, encompassing Gary, Hammond, and East Chicago. Crown Point, the county seat, holds the “Grand Old Lady” – the 1878-1880 former Lake County Courthouse (National Register of Historic Places), now home to the Lake County Historical Society Museum.
Step 1: figure out which path applies
Indiana has NOT adopted the Uniform Probate Code – probate is governed by Indiana Code Title 29. Indiana offers several tracks depending on estate size and complexity:
Small Estate Affidavit – for estates where the gross probate estate (less liens, encumbrances, and funeral expenses) is $100,000 or less. Available 45 days after death. The affidavit must be signed and recorded with the county recorder’s office before a personal representative is appointed. No court filing is required.
Devolution of Real Estate Affidavit – a separate affidavit specifically for transferring real property, available 7 months after death, with no value limit on the real estate, recorded with the county recorder.
Unsupervised Administration – a simplified probate track available when the estate is solvent and all inheritors agree; fewer court appearances and filings than supervised administration.
Supervised Administration – full court oversight, used for contested, complex, or insolvent estates.
Step 2: filing for formal probate
File a Petition for Probate of Will and for Issuance of Letters (if there’s a will) or a Petition for Appointment of Personal Representative (if intestate) with the Lake County Circuit Court’s Probate division.
The court reviews the will for compliance with Indiana Code § 29-1-5-3 (in writing, signed by the testator, witnessed by at least 2 credible witnesses).
The court issues Letters Testamentary (with a will) or Letters of Administration (intestate) appointing the personal representative.
Publish notice to creditors; creditors generally have a limited window (commonly 3 months from first publication) to file claims.
The personal representative marshals assets, pays valid debts and expenses, and distributes the estate.
File a closing statement or final accounting to formally close the estate.
What it costs
Indiana does not have a state estate or inheritance tax.
Filing fees vary by county – confirm current amounts with the Lake County Circuit Court.
Indiana has no statutory fee schedule for attorneys or personal representatives – fees must be “reasonable” and are subject to court approval.
Typical timelines: Small Estate Affidavit – a minimum 45-day wait; Unsupervised Administration – roughly 6-9 months if uncontested; Supervised Administration – 9-12+ months.
