Regulatory framework
The code baseline for Washington County.
The currently published City of Washington Chapter 4 incorporates the National Building Code, 1976 Edition Abbreviated; National Electrical Code, 1975 Edition; and Uniform Plumbing Code, 1973 Edition, with local amendments. No newer 2026 technical-code adoption was verified on the official site; confirm the current code copies with City Hall before relying on these editions.
