Old Lake County Courthouse
The 1878 Cochrane-designed landmark on the square, now a museum with shops and event space.
Downtown Crown Point / Historic Courthouse Square · Crown Point, IN
Additions and restorations around the Grand Old Lady
The blocks around Crown Point's courthouse square hold the oldest housing stock in Lake County — Italianate, Queen Anne, Foursquare, and Craftsman houses on narrow 1870s-to-1920s lots. It is also the one part of the city where a Certificate of Appropriateness comes before the building permit, so the drawings have to answer to the historic guidelines as well as the zoning table.
History & architecture
How Downtown Crown Point / Historic Courthouse Square was built
Crown Point was founded in 1834 by Solon Robinson and became the Lake County seat in 1840, which set the public square at the center of the town plan and made the surrounding blocks the first to build out.
The Lake County Courthouse — the 'Grand Old Lady' — went up in 1878 to a design by Chicago architect John C. Cochrane, mixing Romanesque, Second Empire, and Georgian influences. It now houses the Lake County Historical Society museum and ground-floor shops.
From the 1920s through the 1940s the county's fast marriage licensing made Crown Point the 'Marriage Mill,' bringing a stream of couples and celebrities to the square and funding a wave of downtown commercial building.
Houses filled the surrounding grid between the 1870s and the 1920s: Italianate and Queen Anne first, then Foursquares, Colonial Revival, and Craftsman bungalows, with Moderne commercial infill arriving mid-century.
The Crown Point Courthouse Square Historic District was listed on the National Register in 2004, with boundary increases in 2005 and 2007 that added additional commercial frontage including a Moderne building at 208 Main Street.

Permitting path
- 1Check whether the property sits inside the Crown Point Courthouse Square Historic District. The district was listed on the National Register in 2004 with boundary increases in 2005 and 2007, and the local district drives the review.
- 2Exterior work inside the local district needs a Certificate of Appropriateness from the Crown Point Historic Preservation Commission before a building permit, under Indiana's historic preservation statute (IC 36-7-11).
- 3The commission works from the city's Historic District Guidelines, which cover residential standards, materials, windows, chimneys, porches, and accessibility. Design to the guidelines rather than asking for exceptions.
- 4National Register listing alone does not restrict private work. It is the local designation and the commission's jurisdiction that trigger the COA, so confirm which applies to the specific address.
- 5After the COA, Planning & Zoning handles the zoning review and the Building Department issues the permit. Undersized historic lots frequently need a BZA variance as well.
Why it matters
Downtown Crown Point / Historic Courthouse Square's place in Crown Point
This is the civic and symbolic center of Lake County — the courthouse, the museums, the festivals, and the county's most photographed streetscape.
It holds Crown Point's only concentration of pre-1900 housing, which makes restoration-grade work here different from anything else in the city.
Downtown reinvestment has pushed values up on the surrounding residential blocks, which is why so many projects here are additions and full renovations rather than teardowns.

What this means for your Downtown Crown Point / Historic Courthouse Square project
- Put the addition behind the house. The guidelines and the commission both reward work that leaves the primary street facade intact and reads as subordinate from the sidewalk.
- Windows are the most common sticking point. Repairing original sash, or matching profile, muntin pattern, and reveal depth in a replacement, avoids the most predictable COA comment.
- Original lots are narrow. A side-yard addition usually fails the setback before it fails the review, so a rear or rear-corner strategy is generally the workable one.
- Porches carry the character of these blocks. Column proportion, railing height, and floor material matter more than the size of what is behind them.
- Detached garages and carriage-style accessory buildings fit the historic pattern well and are often the cleanest way to add space, but they count toward lot coverage.
- Document existing conditions properly. A measured as-built set with good photographs shortens the COA discussion and gives the commission something to approve rather than interpret.
