Smoke and Smells Through Shared Walls

Quick answer: Secondhand smoke seeps through light fixtures, outlets, ceiling spaces and doorways in apartment buildings, and can’t be completely controlled by ventilation or air cleaning (EPA). Read your lease for a smoke-free policy, tell your landlord in writing, and ask your local health department about smoke-free rules where you live (EPA). Cooking smells are usually solved with a polite talk and good ventilation. This is general guidance, not legal advice. Check your lease and your local and state rules.
⚠ Safety first:
- Smell gas (rotten eggs)? That’s not a neighbor issue: get out and call 911 or the gas company from outside. See Day One.
- Smell smoke and see fire or haze? Call 911.
- Don’t take apart outlets or light fixtures to seal them; that’s for the landlord or an electrician.
Steps: easiest & free first
- Find where it comes inFREE
Sniff around the front door, outlets, light fixtures, vents and under sinks (EPA lists these paths). - Seal the door gapSHOP
A removable door sweep and stick-on weatherstripping on your entry door. Ask before caulking. - Run your fansFREE
Use your bathroom fan and range hood. See range hood & bath fan. - Run an air cleanerSHOP
It can help with particles but won’t fully fix smoke (EPA). See choosing an air purifier. - Talk politely (cooking smells)FREE
See how to bring it up. - Check the lease and tell your landlord in writingFREE
Look for a smoke-free policy (EPA). Ask the landlord to seal gaps between units. See involving your landlord. - Ask local health expertsFREE
Your local health department may know of state or county codes or smoke-free ordinances; the American Lung Association (1-800-LUNG-USA) can also help (EPA).
⚠ When to call a pro: threats, harassment or anything that feels unsafe (call 911 if in danger); ongoing problems that talking hasn’t fixed (go to your landlord in writing, then local services like 311 or community mediation); and smoke, leaks or pests coming from another unit, which are building problems your landlord should handle. If you’re harassed because of your race, disability, religion, sex, national origin, color or family status, you can report it to HUD (1-800-669-9777). Renting? See what you can fix vs. call your landlord.
💡 Prevent it: Apartment hunting? Ask whether the building is smoke-free before you sign, and get the policy in writing.
