“Your laundry by-law could state that the communal laundry room is only available to lots which do not otherwise provide laundry facilities. This could potentially invalidate the by-law by being “harsh, unconscionable or oppressive” (sections 139, 150), so it may be a good idea to have a strata lawyer draft the by-law to minimise that risk.”
Quirky makes a good point here. Even if a lot has it’s own laundry facility, the owner/resident might want to use the communal laundry if their washing machine breaks down, or if they have a lot of people staying over. So communicating and asking the opinion of all owners is important because you’d be removing a facility that is currently available to everyone.
