A high utility bill is easier to review once you know how it was calculated. Start by identifying direct billing, submetering or RUBS, then check the service dates, formula, usage and added fees.
RUBS allocates shared property expense using a formula. Submetering uses measured usage associated with a unit. Direct utility service is different again. A bill review should follow the actual method in your lease and statement.
