Where the old odor lives
A suite that smells when the door is first opened is telling a prospective tenant something, but the smell in a closed, unconditioned space is often stronger than it will be once the HVAC runs. The reverse can also happen: a suite that seems fine on a mild tour day can smell strongly once the heat comes on and warms the materials holding the odor.
In practice, odor from long occupancy settles in the most porous materials. Acoustic ceiling tiles absorb smoke and cooking vapor. Carpet and pad hold spills and residue. Fiberglass duct liner and flexible duct collect grease and smoke film. Paint can look clean while the drywall behind it carries tobacco or cooking residue. Restaurants, salons, nail studios, hot yoga rooms, smoke shops and some light manufacturing uses leave the strongest traces.
Common previous uses and what they leave behind
| Previous use | Typical residue | Materials most affected |
|---|---|---|
| Restaurant or café | Grease film, cooking odor | Ceiling tiles, ducts, walls near the line, floor drains |
| Salon or nail studio | Solvent, acetone and chemical odors | Ceiling tiles, exhaust ducts, carpet |
| Smoke shop or smoking allowed | Tar and nicotine film | Every surface, especially ceilings and ducts |
| Fitness or hot yoga | Body odor, humidity, sweat in flooring | Rubber or vinyl floors, subfloor, wall finishes |
| Medical or dental | Disinfectant and chemical odors, dried drains | Drains, cabinetry, ceiling tiles |
| Light industrial or print | Inks, oils, solvents | Concrete floors, ceiling, mechanical equipment |
Questions to ask before signing
Ask these of the listing broker or landlord, and get answers in writing where possible.
- What was the previous use, and how long did that tenant occupy the space?
- Will ceiling tiles, carpet or duct liner be replaced before delivery, and at whose cost?
- Will the HVAC system be cleaned or inspected, including the rooftop unit serving this suite?
- Are there floor drains, grease interceptors or abandoned plumbing from the previous use?
- Can the suite be toured with the HVAC running at normal settings?
- If an odor remains after move-in, does the lease say who is responsible for addressing it?
Planning the work around a buildout
If the tenant is doing improvements anyway, odor work fits best at the start. Demolition removes many of the worst materials. Any remaining odor in walls, ducts or concrete can be addressed while the space is empty and before new finishes go in, because treatment that needs an unoccupied space is far easier to schedule before furniture, equipment and staff arrive. Sealing a surface that still holds residue under fresh paint rarely works without cleaning first.
