Odor complaints are among the most common quality-of-life issues in multifamily buildings.

Field Tips

High-rises stack odor problems literally — a lobby smells like the basement, and the penthouse smells like the chute.

1The stack effect drives odor upward in winter and downward in summer — plan HVAC dispensing to counter.
2Seal every chase penetration; unsealed penetrations are highways for kitchen and bathroom odors.
3Balance HVAC yearly — an unbalanced system creates pressure differentials that pull odor between units.
4Address the chute, waste room, and ejector pit as a single program, not three vendors.
5Add corridor air-freshening tuned to the building's signature scent, not off-the-shelf fragrance.
6Investigate 'ghost odors' with a smoke pencil; they usually trace to a specific chase or shaft.
7In mixed-use towers, isolate restaurant exhaust — commercial kitchen odor migrates through shared HVAC.
8Cap unused floor drains with trap seal devices; abandoned units are silent odor sources.

Restroom smell is 80% urine salts on grout and 20% ventilation. Commercial air fresheners come last.

1Deep-clean grout monthly with an enzymatic cleaner — bleach won't touch urine salts.
2Verify exhaust fans move air at least 2 CFM per sq ft; test with a piece of tissue.
3Install continuous passive dispensers on the return-air path, not above the urinal.
4Replace urinal traps every 12 months in high-traffic restrooms; sediment holds odor.
5Waterless urinals need cartridge changes on schedule — a skipped change smells worse than a regular urinal.
6Check floor drains weekly for dry traps; a dry trap in a restroom is instant sewer odor.
7Use a light, clean fragrance — heavy floral in a restroom reads as a cover-up.
8Post cleaning logs on the door; guests smell what they see logged, not the reverse.
