A mayor's tenure in office varies, as some cities have laws in place that limit the length of a mayor's term. The most common term length in the United States is four years, with the second most common being two years.
While many cities only place restrictions on the length of a mayor's term, some cities also limit the number of terms a mayor can serve. The most common term limit for most cities is two terms, with a three term limit being the second most popular choice. Larger cities are far more likely to impose term limits on their mayors in comparison to smaller cities and towns.
