Neighborhood Zoning Codes

City codes relating to zoning and community maintenance are a means of ensuring that the community’s land uses are compatibly located and used for the health, safety and general welfare of the community. The city of Aurora has a commitment to provide safe and sanitary living conditions for all of its residents. It takes a cooperative effort of investors, owners, tenants and the city to achieve a successful property maintenance program. Please contact the Neighborhood Support Division for further information.

As a resident or property owner, it is your responsibility to keep city sidewalks adjacent to your property free and clear of snow and ice, even though the sidewalks may be behind or outside the rear and side fences and adjacent to any street.

Snow and ice must be removed within 24 hours after a snowfall ends, and 48 hours after a snow emergency is declared by the city.

To ensure pedestrian safety, code enforcement officers respond to citizen complaints concerning lack of snow and ice removal from sidewalks. An Administrative Fee, $25 for single-family and $50 for all others, will be imposed after 24 hours and again after 48 hours, if the snow is not removed. The city’s contractor will then be requested to remove the snow and/or ice, and the property owner or financial institution will be billed for all costs incurred.
