An electrician or electrical contractor lacks a standardized template for performing load calculations on multi-family dwellings (duplex or greater), as their city only provides a single-family template.

No template or guidance exists for multi-family load calculations from the city; existing single-family template is insufficient, leading to manual or ad-hoc calculations that risk errors and non-compliance.
