Full Breakdown

Aurora, Colorado requires new or remodeled residential and commercial buildings inside designated aircraft noise districts around Buckley Space Force Base, Denver International Airport, Centennial Airport and Front Range Airport to meet minimum outside-to-inside transmission loss (OITL) standards for exterior walls, windows, doors and vents. Required OITL ranges from 25 to 30 decibels depending on the district (NID, SNID, CANA, NIBA, LDN 65/55 contours), verified by one of three design methods: a prescriptive construction method, an engineering-analysis method, or post-construction acoustic testing.

Violations & Fines

Building permits for covered projects require compliance with one of the three design methods and, for Method III, verified testing before occupancy; noncompliant construction is subject to the city's standard building-code enforcement and permit denial.

Frequently Asked Questions

Does this apply everywhere in Aurora, Colorado?
No: only inside the mapped noise districts and LDN contours around Buckley Space Force Base, DIA, Centennial and Front Range Airport; the map is on file with the city clerk.
Which airport noise rules govern Buckley Space Force Base itself?
None locally. Buckley is federal land; Aurora's article regulates civilian building construction in noise-impacted areas nearby, not the base.
