Conclusions Revitalizing neighborhoods and addressing problems associated with aging

housing is one of City Council’s top priorities

In 1990, 79% of our housing was in standard condition

28 years later, 86% is in standard condition

Based upon what we think makes a good neighborhood, how can we

explain the results:

Property owners are doing a relatively good job of maintaining their properties

Code Enforcement proactively patrols the city and addresses code violations

Approx. 9,800 building violations and 25,200 property violations are cited/year

The City does a great job at maintaining public safety, providing core public

services, and maintaining public facilities and infrastructure

For the very small number of property owners who may not be able to afford to

maintain or re-investment, DHNP offers programs to assist or connects owners to

resources
