CONDOMINIUMS & HOA ACCOUNTS

Water supplier or unit billing company?

The water utility supplies the building’s master meter. A submeter or billing company may bill individual units. Ask your HOA which firm it contracts with and whether water is included in your assessments. Residents generally use the contracted firm rather than choose their own.

Submetering measures unit use; RUBS allocates shared costs by a formula. Confirm which method your building uses.
