A “home rule” petition on how affordable housing stock is calculated locally has been shot down by the state numerous times, but Wareham officials aren’t taking “no” for an answer.

“We’ll keep sending it until doomsday, until we finally get what we want,” said Selectman Patrick Tropeano.

On Tuesday, the board again approved a petition that would allow the town count mobile homes as affordable housing in town. The petition must be approved by voters at Town Meeting, at which time it will then be sent to the state legislature for consideration.

State law Chapter 40B, designed to encourage the development of housing affordable to low-and moderate-income people, penalizes communities in which less than 10 percent of the housing stock is considered affordable, by allowing developers to avoid local regulations if constructing affordable housing.

Because of Chapter 40B’s definition of affordable housing, Wareham has never met the 10 percent threshold. Currently, the percentage of homes considered affordable is 7.5 percent. If the roughly 1,100 units in the town’s mobile home parks were to be considered affordable housing, the town would meet the 10 percent requirement.

In 2015, voters at April Town Meeting approved sending a bill that would allow just that, however, the bill has been relegated to a “study order” in the state House of Representatives, which means it won’t be acted on any time soon.

Chair Judith Whiteside said a similar bill “previously passed this board unanimously, then Town Meeting and then it was buried,” she said referring to legislators at the state level.

Support for the measure also came from Jeff Hallahan, president of the Massachusetts Manufactured Housing Association. Hallahan is a member of the state’s Manufactured Homes Commission and owns the Garden Homes Estates mobile park in Wareham.

Hallahan said he appeared at the meeting to dispel rumors about his industry’s stance on the petition.

“I was surprised to hear it wasn’t rubber stamped on Beacon Hill,” he said. “What trickled down to me was that my industry, the owners, blocked it…The Massachusetts Manufactured Housing Association has never opposed this. I will give you my word on that.”

He said local owners were not against to the rule change and were looking forward to working with officials.

“We support a partnership to the extent that one is necessary,” said Hallahan. “We want to be a beneficial member of this community. If we’re being identified as an obstacle to progress, I have a problem with that.”

With Selectmen’s approval the agenda item will appear before voters at the Fall Town Meeting, set for Oct. 24.
