A commercial district with people living above the shops
The Shelbyville Commercial Historic District was listed on the National Register in 1984. The listing records about 41.5 acres, 149 contributing buildings and development from roughly 1822 to the 1930s, in an area roughly bounded by Broadway, Tompkins, Mechanic and Noble Streets.
The City of Shelbyville's 2023 Neighborhood Study describes downtown the same way in plainer terms. Some of the city's oldest buildings are here, and many have upstairs apartments for rent. The Shelby County Courthouse, built in 1936 and 1937 at 407 South Harrison Street, is one of the best-known landmarks nearby.
Downtown is not a residential subdivision, and this page does not treat it as one. For the historic houses next to it, see our guide to the Westside Historic District.
What owners and tenants should sort out first
In a building with a shop below and an apartment above, water lines, drain stacks and shutoff valves are often shared. A leak upstairs can show up as a stain in the ceiling of the business below, and the cause may sit in a wall neither tenant can see.
Before an emergency, find out where each unit's shutoff is, who has the key to the space that holds it, and who is responsible for which pipe. The lease usually answers that last question, along with Indiana law. A plumber can tell you what is wrong, but not who owes the bill.
Before you sign a lease or buy a downtown building
Plumbing questions are cheaper to ask early than to answer later.
- Ask where the main shutoff is and whether each unit has its own.
- Ask whether the building sewer has been camera inspected, and request a copy. See sewer inspection.
- Ask which pipes and fixtures are the tenant's responsibility under the lease.
- For a restaurant, ask whether a grease trap or interceptor exists and where it is.
- Ask for the record of past permits and any major plumbing changes.
Restaurants, kitchens and grease lines
Fat, oil and grease that cool inside a drain are a common cause of kitchen backups in any city. Whether a kitchen needs a grease trap or interceptor, and how often it must be serviced, is set by local rules and the plumbing code. Ask the City of Shelbyville before you buy or install equipment.
Our commercial plumbing page covers kitchen and shop work, and hydro jetting explains how a greasy line is cleaned out. Regular service is cheaper than a Saturday-night backup.
Older buildings and open walls
A building that has been remodeled in stages can hold pipe from several eras. That is normal, and it is not a defect by itself. It does mean a plumber should look before quoting. Ask for a camera view of drains and for a plan that shows where lines run before any wall is opened.
Rivers, floods and lower levels
Shelbyville sits at the fork of the Little Blue and Big Blue Rivers. Purdue's account of the March 1913 flood says the water reached the first alley east of the Public Square. In April 2025 the Big Blue crested at 19.98 feet at Shelbyville, the second highest on record, according to the National Weather Service.
Those are history, not a forecast for any block. If your building has a basement or a lower level, check the FEMA flood map through the city, keep a working floor drain, and ask about a sump pump if water has ever entered. The city's flood page says to move valuables and electronics to higher ground.

Downtown Shelbyville plumbing questions
Mostly not. It is a commercial district, though the city's neighborhood study notes many buildings have apartments upstairs. People who live there are usually renters, so the lease decides who handles a repair.
That depends on local sewer rules and the plumbing code. Ask the City of Shelbyville before installing or buying kitchen equipment. A plumber can help size and place a trap once you know the requirement.
The city says only plumbing contractors registered with it can apply for plumbing permits. For a commercial remodel, ask Planning and Building what review applies before work starts.
Shut off water to the unit above if you can reach the shutoff, move stock away from the stain and call. Tell the plumber whether the apartment above has had any problems. See leak detection for how a hidden leak is traced.
For a kitchen or a building with a history of backups, yes, it can be worth it. See drain cleaning. For a quiet office, camera inspection before problems appear is usually the better first step.
