Shelton’s charter revision, which goes before voters this November, has come up with an interesting change:

And if the recommendations pass, the city’s longest-serving member of the Board of Aldermen will have a difficult decision to make � give up either that seat or his position as the city’s Democratic registrar of voters.
[...]
Those changes include a provision that prohibits any elected official from holding two elected offices. Initially, the commission had included a provision that Aldermen Jack Finn, D-1, and Jason Perillo, R-2, would be exempt from that requirement, but later took that out after Perillo protested that it would be wrong to give the two men that pass. That means that Finn would have to choose between his two jobs. Perillo has said he would give up his seat on the Board of Aldermen in favor of his job representing the 113th District in the state General Assembly. (Ramunni)

This, of course, was an issue when then-State Sen. Bill Finch was elected mayor of Bridgeport. He continued to hold his senate seat for months before resigning–in a move that some Democrats think cost them the seat (the logic being that if he had resigned earlier, the special election could have been held on the day of the presidential primary) and their supermajority.

I don’t know if other towns have similar provisions, but it’s still pretty rare for elected officials to hold two offices in any case.
