What shapes odor problems here

Jefferson Park packs a lot of housing into a small area. Older one-story homes on small lots sit next to three- and four-story townhomes and slot homes built close together. Lakewood Gulch and the South Platte corridor to the south and east support rats, raccoons and birds, and stadium events leave trash in streets and alleys.

In attached townhomes, an animal can die in a party wall, a shared attic space or a ceiling between units, which means the smell may be in your home while the source is next door. In older houses, crawl spaces and detached garages are the usual places.

Questions to answer before calling anyone

  1. Is the smell strongest at a wall you share with another unit?
  2. Has anyone in the building or on the block seen rats or raccoons recently?
  3. Was bait put out by you, the HOA or a neighbor in the last few weeks?
  4. Does the smell get stronger after event days or warm afternoons?
  5. Can you reach the area without opening a wall, such as through an attic hatch or crawl access?

Townhome versus older house

Attached townhome

  • Party walls and shared roof spaces
  • HOA usually controls exterior and common areas
  • Source may be in a neighbor's unit
  • Written reports to the association matter

Older detached house

  • Crawl space, basement and garage are prime spots
  • Owner controls access and repairs
  • Gaps in foundation and vents are common
  • Search can start immediately

Older houses in the neighborhood

The older homes in Jefferson Park are mostly small single-story houses with crawl spaces or small basements and detached garages. Rats from the gulch and alleys find gaps at foundations and garage doors. A smell in one of these houses usually comes from below, and checking the crawl space or basement is the first step.

Townhome residents, by contrast, should start with the association, since walls, roofs and shared spaces are often common elements.

Common questions

Who pays if the dead animal is in a shared wall?

That depends on the association's documents, which define common elements and unit boundaries. Ask the HOA in writing and keep copies.

Do rats come from the stadium?

Event trash adds food for a while, but the gulch, alleys and nearby greenways support rats year-round. Sealing homes matters most.
