No, standard Leviton Decora switches do not require special or proprietary wiring compared to traditional toggle switches, as they utilize the exact same standard branch circuit conductors (hot, load, and ground). However, smart variants within the Decora Smart product family almost universally require a neutral wire bundle (white) inside the electrical wall box to power their internal Wi-Fi radios and microcontrollers—a requirement common among modern smart switches. If replacing an older switch in a home lacking a neutral wire, specialized non-neutral smart switches or electrical rewiring may be necessary. Verification: Remove your existing wall plate to visually inspect the wall box interior and confirm the presence of bundled neutral wires before purchasing smart switches.
