Andover residents will decide nine statewide ballot questions on Nov. 3, covering gun regulation, recreational marijuana, single-family zoning and same-day voter registration.

The election warrant, signed Sept. 28 by all five Select Board members including Chair Ellen M. Townson, lists the questions alongside races for governor, U.S. Senate, attorney general and other offices. Nine questions ties the most ever on a Massachusetts ballot since the state created the initiative petition process in 1918, WCVB reported.

Here is what each question would do:

Question 1 would make most records held by the Legislature and the Governor's Office subject to the state's public records law. Certain policy-development documents and constituent requests for services would be exempt.

Question 2 would let employees of the Committee for Public Counsel Services, the state's public defender agency, bargain collectively.

Question 3 would replace separate party primaries with a single all-candidate primary. The top two vote-getters would advance to the general election regardless of party.

Question 4 would allow eligible residents to register to vote or update their address at the polls on Election Day, starting Jan. 1, 2028. All other New England states already permit same-day registration, according to the Cape Cod Times.

Question 5 would change the state revenue cap by tying it to a three-year average of wage growth. Revenue above the limit, including proceeds from the millionaire surtax, would be refunded to taxpayers.

Question 6 would create a Nature for All Fund, directing 50% of state taxes on sporting goods, recreational vehicles and golf courses toward land conservation, parks and trails in its first year. That share rises to 100% after July 1, 2028.

Question 7 would allow single-family homes on lots as small as 5,000 square feet with 50 feet of street frontage, provided the lot has public sewer and water. Towns could still regulate height, setbacks and parking.

Question 8 would repeal the laws allowing retail sale of recreational marijuana. Adults 21 and older could still possess up to one ounce, including no more than five grams of concentrate. Existing recreational shops could apply to become licensed medical dispensaries. The change would take effect Jan. 1, 2028.

Question 9 is the ballot's only referendum on an existing law. A yes vote keeps the 2024 firearms law signed by Gov. Maura Healey, which expanded red-flag protection orders, penalized ghost guns, raised the minimum age for semiautomatic rifles and shotguns to 21, and banned firearms in government buildings, polling locations and schools. A no vote repeals it. Gun rights advocates collected signatures to place the question on the ballot, WBUR reported.

Polls open 7 a.m. to 8 p.m. on Nov. 3 at three Andover locations: the Cormier Youth Center on Whittier Court (Precincts 1 and 3), Wood Hill Middle School gymnasium on High Plain Road (Precincts 4, 4A, 5 and 6), and the Richard J. Collins Field House at Andover High School on Shawsheen Road (Precincts 2, 7, 8, 9 and 10).

Statewide early voting runs Oct. 17 through Oct. 30. The voter registration deadline is Oct. 24, and vote-by-mail applications are due by 5 p.m. Oct. 27. Secretary of State William Galvin's office is mailing voters an 88-page guide to the questions.
