Utilities, Utility Districts - As enacted, makes revisions to present law relative to utilities. - Amends TCA Title 7; Title 13, Chapter 7; Title 65 and Title 68.

SB 1139 requires utilities (including municipal or county-owned water, electric, and gas providers) to review development plans for compliance with infrastructure codes within 30 days. If a utility misses this deadline, developers can hire a third-party examiner (an engineer with relevant expertise) to review the plans, submit the findings to the utility, and the plans are deemed approved if the utility fails to act within 10 business days. The bill also limits utility inspection fees for approved projects to 2% of the development's total cost and mandates utilities to provide a schedule of approved materials. This directly affects developers seeking permits for new construction and utilities managing infrastructure reviews.
