How Aurora Handles Building Setbacks & Zoning: A Practical Guide

Aurora maintains 118 local ordinances across all categories, and 3 of those deal specifically with building setbacks & zoning. Here is a breakdown of what the city actually requires, what is prohibited, and where Aurora falls on the strict-to-permissive spectrum compared to other cities.

Setback Rules

Aurora's UDO establishes setback requirements by zoning district. Residential setbacks typically require 25-30 feet front, 5-10 feet side, and 25-30 feet rear. Setbacks vary by zone and lot configuration. Variances available through the Zoning Board.

Key details: Front: 25-30 ft typical. Side: 5-10 ft typical. Rear: 25-30 ft typical. Variances: Zoning Board of Appeals.

Construction in setback: stop-work order. Must seek variance or relocate structure.

Structure Height Limits

Aurora's UDO limits residential building height typically to 35 feet (2.5 stories). ADUs limited to 24 feet. Height measured from grade to roof peak. Exceptions for chimneys, antennas, and mechanical equipment.

Key details: Residential: 35 ft / 2.5 stories. ADU: 24 ft maximum. Fence: 9 ft maximum. Exceptions: Chimneys, antennas.

Exceeding height limit: construction must stop, seek variance, or reduce height.

Lot Coverage Limits

Aurora's UDO limits lot coverage (buildings and impervious surfaces) by zoning district. Typical residential coverage is 30-40% of lot area. All structures including house, garage, shed, and ADU count toward coverage.

Key details: Residential: 30-40% typical. Includes: All structures + paved surfaces. ADU: Counts toward coverage. Permeable: May get partial credit.

Exceeding lot coverage: must reduce or seek variance. Unpermitted coverage: code violation.

The Bottom Line

Aurora's building setbacks & zoning rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Aurora is broadly strict or permissive.

All of the above reflects Aurora's municipal code as of our last review. If you need specifics on fines, exemptions, or filing requirements, the detailed ordinance pages linked above have the full breakdown.
