Martha’s Vineyard public health officials were planning to reintroduce Islandwide restrictions on the construction and building industry Thursday.

Martha’s Vineyard towns are seeing a boom in residential construction projects, as building demands soar both up-Island and down. The majority of the activity is in renovations.

Selectmen and boards of health in six towns have agreed to further loosen restrictions on construction and other trades effective May 11.

Building and landscaping projects stuttered back into gear for the first time in more than a month, as one and two-person crews returned to work under strict guidelines.

Following a monthlong moratorium on construction and other trades, one and two-person crews will be allowed back to work Monday under strict new guidelines.

Five of the six Vineyard towns have settled on April 27 as the date to phase in limited construction work, voting to extend strict building moratoriums for an another 10 days.

A tense conference call between Island town leaders and the head of the hospital over relaxing the construction ban split the Island along geographic lines.

Three Island towns were presented with a plan Tuesday to take steps to get some construction workers back on the job, but there were mixed reviews, and all paused after hearing strong objection from Martha’s Vineyard Hospital president and chief executive officer Denise Schepici.

More than 100 Island contractors and tradesmen who have been affected by the construction moratorium joined a conference call Monday.
