The area in brief

Where
Along West Colfax Avenue between Federal and Sheridan Boulevards, south of Sloan's Lake, with Lakewood Gulch running through.
Housing
Older garden apartments, small houses, converted motels and new mixed-use buildings near light rail.
Common animals
Rats and mice near the corridor and gulch; pigeons on older roofs and signs.
Renters
A large share of residents rent, so landlords and managers handle most repairs.

Apartments and older buildings

Older apartment buildings along the corridor often have shared crawl spaces, boiler rooms and attic spaces that connect several units. Pigeons nest on ledges and in vents, and rodents move between units through plumbing chases. When one dies, the smell can show up in a unit that had nothing to do with it.

Tenants usually cannot open walls or enter shared spaces. The useful steps are describing the smell clearly, reporting it in writing to the manager, and noting any flies or stains. Managers can then send maintenance or a pest provider into the right spot.

Reporting in an apartment building

In a large building, maintenance staff handle many requests at once. A clear report gets prioritized: the unit, the room, the wall or ceiling area, when the smell started and whether flies or stains have appeared. If neighbors smell it too, a single combined report naming each unit helps maintenance see the pattern.

If the smell is in a common area like a corridor or laundry room, report that location specifically, since the source may be in a shared space no tenant can access.

Common questions

I rent. Can I hire someone to find the smell?

Ask the landlord first. Opening walls or entering shared spaces requires the owner's permission, and most leases make pest and repair issues the owner's responsibility.

Is a converted motel different from an apartment?

Converted buildings often have shared ceiling spaces and old ventilation, so odor can travel between rooms more easily.
