Full Breakdown
The city adopts the National Electrical Code 2020 Edition, as amended or as adopted by the State of Texas, under Sec. 14.002(a)(7). Sec. 14.370 requires anyone applying for a building (electrical) permit to be a state-licensed electrical contractor, or exempt under state law. A state-licensed contractor must register with the city annually and show proof of license and insurance before working in the city. A homeowner claiming the state-law exemption must file an affidavit with the building official confirming they own and reside in the dwelling. Article 10 (Sec. 14.291-14.292) also layers local amendments onto the NEC, including a requirement for outside service disconnects and specific service-mast attachment rules.
Violations & Fines
Electrical work performed without a permit, by an unregistered/unlicensed contractor, or that fails to meet the locally amended NEC standards (e.g., service disconnect and labeling rules) is subject to code enforcement citation and stop-work action by the building official.
