Why newer construction behaves differently
Much of the housing toward the eastern edge of Aurora was built in more recent decades, often as single-family homes and townhomes with attached garages. Newer construction frequently has tighter envelopes, which means less natural air exchange. When a tenant leaves behind a source of smell, the house may hold it longer than an older, draftier one would.
That is a general tendency, not a rule. Individual houses differ with builder, age, ventilation design and how they were maintained, so a landlord should check each property rather than assume.
Newer houses also tend to have forced-air heating and cooling with ducts running through several areas. Smell that reaches the air system can reach every room, which makes the filter and return grilles a natural first stop.
Newer subdivisions often have homeowners associations with their own expectations for exterior appearance and trash handling. Where a rental sits in such a community, check what the rules say about dumpsters, work vehicles and noise before arranging cleanup, so a turnover does not trigger a notice.
New carpet and fresh paint can themselves create a smell in a tight house. Allow time for new materials to air out, and run the ventilation fans, so a landlord does not confuse that temporary smell with a leftover problem.
Things worth keeping in mind
- Housing mix
- Often single-family houses and townhomes, though the mix varies by neighborhood
- Air exchange
- Can be lower in tightly built homes, so smell may linger
- Garages
- Attached garages can feed smell to adjoining rooms
- Ventilation
- Bath and kitchen fans matter more when windows stay closed
Turnover checks that suit this kind of house
- Test every exhaust fan and confirm it vents outside.
- Replace the furnace filter and look at the return grille.
- Check the door between the garage and the house for a worn seal.
- Open windows during cleaning to move air through a closed house.
- Look at closets and storage under stairs, where air tends to stagnate.
- Recheck the smell after the house has been closed up for a day.
Common questions
Do newer houses have fewer odor problems?
They can, but a tight house also holds smell longer once something is left behind. Look at ventilation, the air system and the garage connection.
