Summary

Indiana's Unsafe Building Law (IC 36-7-9) lets Carmel, Fishers, Noblesville, Westfield and Hamilton County order the repair, vacation or demolition of blighted structures. A building that is structurally impaired, a fire hazard, a public nuisance, or vacant and unmaintained is legally 'unsafe.'

These county ordinances apply to unincorporated areas of Hamilton County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

a building or structure, or any part of a building or structure, that is: (1) in an impaired structural condition that makes it unsafe to a person or property; (2) a fire hazard; (3) a hazard to the public health; (4) a public nuisance; ... or (6) vacant or blighted and not maintained ... is considered an unsafe building.

Full Breakdown

Hamilton County is heavily incorporated, so blight is enforced mostly by city code-enforcement departments (Carmel, Fishers, Noblesville, Westfield), each of which has adopted a property-maintenance code; the county enforces in the unincorporated area. All draw authority from IC 36-7-9, which defines an 'unsafe building' and lets a hearing authority order the owner to repair, secure, or demolish it. If the owner fails, the municipality may perform the work and recover its costs. Vacant, deteriorated structures that attract vermin, dumping or vandalism are singled out by statute as blight that decreases neighboring property values.

Violations & Fines

A hearing authority may order repair or demolition; if the owner does not comply the city or county performs the work and bills the owner, recording the unpaid cost as a lien, and may impose civil penalties.
