Aurora stretches across parts of Arapahoe, Adams and Douglas counties, and its housing reflects that spread. The older northwest part of the city has many modest homes from the 1940s through the 1960s, often with basements and long rental histories. Large areas built in the 1970s and 1980s are full of tri-levels, bi-levels and two-story homes with finished lower levels. Southeast Aurora is dominated by newer subdivisions, many with HOAs and tighter, more energy-efficient construction.
Each group brings its own odor themes. Older homes that have been rentals for decades may carry layers of smoke, cooking and tenant history, sometimes hidden under quick paint jobs. Tri-levels and bi-levels have living space partly below grade, which can turn musty after wet weather. Newer, tightly sealed homes hold onto indoor odors longer because less outside air leaks in, so cooking and smoke odors can concentrate even in a house that is only a few years old.
Older north Aurora versus newer southeast Aurora
| Older homes, often near the Colfax corridor | Newer southeast subdivisions |
|---|---|
| Frequent rental and investor history | Tight construction that holds indoor odors |
| Older plumbing and sewer laterals | Finished basements with carpet over slab |
| Basements with older finishes or none | HOA rules that may affect exterior work or contractor access |
| Multiple layers of paint over past residue | Ventilation depending heavily on bath and kitchen fans |
| Smaller lots; detached garages in some areas | Odors from short occupancy can still be concentrated |
Aurora-specific things to check
- In a former rental, ask whether walls were washed before the last paint job; residue can bleed through cheap paint
- In a tri-level, walk the lowest level after a rain and after the sprinklers run
- In a newer home, check that bath fans actually vent outside and that the range hood is not just recirculating
- In any home with a crawl space under an addition, open the hatch
- For HOA communities, confirm rules for contractor parking, dumpsters and exterior work before scheduling
- Ask the City of Aurora building division whether planned removal of finishes or drywall needs a permit
- For water or sewer questions on the public side of the line, ask Aurora Water
