Can an MCST pass By-law to stop smoking at the balconies in a condo?

A writer in his letter to the Forum in  Straits Times today wrote that three condos had passed By-law prohibiting smoking at the balconies and patios. If the balconies and patios are within the strata area of the lots, can any MCST passed such By-law to control  spaces that are  within  the lots of someones,meaning spaces that are  not common property?

Section 32 of the Building Maintenance & Strata Management Act only allows an MCST to pass By-law for the common property.

Smoking is not allowed at  places  spelt in the Smoking (Prohibition at Certain Places) Regulations. Balconies and patios do not appear in the list of prohibited places.

All measures against second hand smoke are good. However, they must be able to withstand challenges legally.
