Mayoral candidate Tito Jackson has racked up more than 100 parking tickets — totaling more than $4,000 in fines — in the past six years in what he says is the byproduct of hectic constituent work, while others warn the fines could harm his campaign.

“You can’t just run up 100 tickets, that’s an awful lot of careless,” said former City Councilor Michael McCormack. “I think Councilor Jackson is coming to realize when you are running for mayor it’s a whole different environment than running for district councilor — you’re running to be CEO of a $3 billion corporation, every misstep is amplified.”

But Jackson said the tickets are a consequence of his work as the Roxbury city councilor and his travels around the city.

“I keep a very active schedule with my constituents and I am always focused on doing the job of councilor. I don’t have a city vehicle or city driver,” Jackson said. “When I receive a ticket I pay it.”

When asked if he thought the high volume of tickets would hurt his campaign, Jackson said, “All of my tickets are paid.”

A Herald review of city fines levied against Jackson, the Roxbury city councilor, and Mayor Martin J. Walsh since 2010, found Jackson had received 109 tickets totaling $4,230 in fines and that all the tickets had been paid. Walsh had no parking tickets during that period.

Records show Jackson received 35 $25 tickets for unpaid parking meters for a total of $875, but his costliest tickets were $1,045 for 19 parking-in-a-loading-zone tickets. He also received 21 $40 tickets — $840 total — for parking in a residential zone. He also had five tickets, for a total of $200, for parking during street cleaning. He received the most tickets in one year, 29, in 2013.

Jackson also paid about $170 in late property tax fees between 2010 and 2012 and $270 in late excise tax fees between 2010 and 2014, city records show. Walsh has paid $8 in late property tax fees.

“Whenever I’ve received a ticket or fine, I’ve paid it,” Jackson said when asked to comment on the excise and property tax fees.

Walsh has been driven in city cars since becoming mayor in 2014, making it unlikely he would have received parking tickets. Former City Councilor Larry DiCara said getting parking tickets was part of living in the city and doubted the volume of Jackson’s fines would hurt his campaign.

“I don’t think it will have an impact one way or another,” DiCara said.

But voters often hold elected officials to higher standards, McCormack said, adding: “You have to be purer than Caesar’s wife.”
