Is it illegal for my neighbour to smoke inside their HDB or condo flat?

Generally no. Smoking inside a private dwelling or on many private balconies is lawful. Enforcement heat sits on prohibited common areas, littered butts, and unreasonable interference claims after mediation — not a blanket indoor ban.

Who do I call for smoke drifting from the next balcony?

Start with mitigation and a polite written ask. Common-area smoking or butt litter can go via OneService / Town Council (HDB) or MA / MCST (condo). Persistent private disputes move to CMC mediation; CDRT is last resort with a dated log.

Does vaping change the neighbour-smoke playbook?

Vaporisers are illegal for everyone in Singapore — that is a separate possession / use offence, not a neighbour mediation tip. See the vaping / tobacco laws guide for pass-risk rules; do not ‘report vaping’ as a substitute for documenting cigarette smoke drift.

Secondhand smoke from neighbours in Singapore

What tenants can do when balcony or corridor smoke drifts in — legal smoking at home, common-area rules, OneService vs MCST, CMC mediation, and CDRT last resorts.

r/askSingapore secondhand-smoke threads share one painful sentence: “NEA said they cannot do anything because he is smoking in his own home.” Often that is legally accurate for private indoor smoking — and still leaves you with a usable playbook.

Split lawful smoking from enforceable breaches

Situation	First rail	Not this
Smoke from neighbour’s living room / own balcony	Mitigation → polite ask → CMC if needed	“NEA must fine indoor home smoking”
Smoking in HDB common corridors / void deck / stairwell	OneService / Town Council / NEA smoking prohibition where applicable	Condo MCST
Smoking in condo common corridors / sky garden / playground	MA / MCST by-laws + estate no-smoking rules	HDB Branch
Cigarette butts thrown from height / litter	OneService / NEA littering	CDRT as first email
Illegal vaporiser use	Separate criminal / composition rail — vaping laws	Neighbour smoke mediation only

Mitigation before escalation

Close windows on the smoker’s schedule; run exhaust / purifier in the affected room
One polite written note (date it) — then stop corridor confrontations
Log dates, times, and where the smoke enters (service yard, bedroom window, bathroom vent)
Kids / asthma make it urgent emotionally; they do not create a new statutory indoor-smoking ban next door

HDB vs condo rails

HDB: common-area smoking and butt litter → OneService / Town Council; private-unit drift → mediation stack
Condo: MA letter citing by-laws / house rules; smoke on common property is the easy win; balcony-to-balcony drift is the hard case covered in condo noise / MCST

CMC and CDRT realism

CMC mediation is the designed middle rail when both households will attend. CDRT is for unreasonable interference — smell / smoke is an explicit example in judiciary guidance — but expect cost, time, and evidence standards. Bring a dated log, not a single bad evening.

Pass and health side-notes

Cigarette smoking by the neighbour is not your immigration problem. Your vaporiser is — vaping / tobacco laws. Haze weeks stack outdoor PSI stress on top of balcony smoke — haze preparedness. Medical emergencies stay on 995 (emergencies).

Dense older towns such as Geylang, Toa Payoh, and Ang Mo Kio see frequent service-yard drift threads; northwest family towns like Bukit Panjang and Boon Lay are not immune when windows face the prevailing breeze.
