Where flex buildings differ

Mixed uses
Offices, labs, workshops, light assembly, storage and distribution can share walls and roof systems
Shared air
Rooftop units and exhaust fans may serve more than one bay or draw from the same dock area
Typical smells
Solvents, adhesives, paint, plastics, cutting oils and cleaning chemicals
Safety first
Unknown chemical odors call for caution, not exploration

Why a smell can feel like it came from nowhere

Industrial and flex parks along the I-25 and US 36 corridors often hold many small tenants. An office bay may share a wall, a roof or a loading area with a workshop. Fumes leave a process through a vent or a door and can be pulled back in by a rooftop unit intake or under a door when pressure differs. The people who smell it may not be the people causing it.

Because several tenants may handle chemicals, it is easy for the answer to be unclear. Starting with a map of who is next to whom, where the exhaust leaves and where each rooftop unit draws air tells more than guessing at the substance.

First moves

  • IfHeadache, dizziness, eye or throat irritationLeave the space and call 911 from outside. Do not investigate.
  • IfStrong chemical smell with no obvious sourceNotify the property manager and ask neighbors whether they are doing similar work.
  • IfSmell tied to a neighbor's work hoursLog the times and ask about exhaust and make-up air for that bay.
  • IfSmell is only at the dockCheck trucks idling, product staging and dock door pressure.
  • IfSmell remains when everyone is goneLook for residue in materials, stored containers or contaminated floor surfaces.

What a property manager should be able to answer

  1. What uses are permitted in neighboring bays under their leases?
  2. How is hazardous material storage handled and reviewed?
  3. Which rooftop units and exhaust fans serve which bays?
  4. Has the fire or building department reviewed any ventilation changes?

Common questions

Can a tenant demand a neighbor stop a smell?
That depends on the leases and local rules. Documented complaints routed through the property manager are the normal first step.
Do chemical odors always mean something dangerous?
No, but the smell is not a reliable measure of risk. When symptoms occur, treat it as a safety matter first.
