Does the National Electrical Code prohibit homeowners from working on home wiring?

Answer: No
Explanation: No. The National Electrical Code (NEC) itself does not generally prohibit a homeowner from doing electrical work on their own home. The NEC is primarily a technical safety standard—it specifies how electrical work must be installed, rather than deciding who is legally allowed to perform it. The important distinction is local law and permitting. Since you're in Phoenix, the City currently adopts the 2023 NEC with Phoenix amendments. Phoenix specifically states that homeowners can do many projects themselves, but electrical updates, rewiring, and additions generally require a permit.
