Estimated Billing. If Seattle Public Utilities or Seattle City Light has billed the
landlord using an estimate of utility service consumed, the billing agent may estimate
the charges to be billed to tenants until billing based on actual consumption resumes.
Upon receipt of a corrected bill showing that the estimated bill overstated charges,
the landlord must refund the difference to tenants. Upon receipt of a corrected bill
showing that the estimated bill understated charges, the landlord may attempt to recover
the underpayment from the tenants that actually incurred the charges during the billing
period, but shall not attempt to recover an underpayment from a tenant who did not
reside in the unit during the billing period in which the charges were incurred.
9.
Submetering. Submetering is permitted as a way of allocating master metered utility
services to tenants provided the following conditions are met:

The submeters must be read prior to each billing.
b.
A landlord may not enter a unit without, and a tenant may not unreasonably withhold,
consent to enter the unit in order to perform submeter installation, reading, repair,
maintenance, and inspection, including removal of the submeter for testing, provided,
however, that a landlord may enter a unit without a tenant's consent in the case of
a submeter leak or emergency related to that unit's submeter.

(i)
The accuracy tolerance for the maximum flow rate shall be within 1.5-percent for all

under-registration for other than Multi-jet submeter types.
