Repairs got underway this week at the Island Theatre in Oak Bluffs.

“We’re watching it very closely,” town administrator Robert Whritenour told the Gazette Wednesday. He said he believed construction began earlier this week inside the crumbling building at the foot of Circuit avenue.

The condition of the vacant theatre owned by the Hall family has been a long-running source of concern in town, and was the subject of a recent flurry of activity in court.

Following a ruling last week from superior court Judge Cornelius Moriarty 2nd, the Halls are now working to try to complete repairs within the next three weeks.

Mr. Whritenour said a building permit has been issued and work is taking place under supervision of the town’s two interim building supervisors, Eladio Gore and Thomas Perry.

Last week Kevin C. Cain, a Canton-based attorney representing the Lucky 7 Realty Trust and Hall family members who are trustees, outlined plans for constructing temporary shear walls to shore up the theatre, subject to securing housing for construction crews and ferrying their vehicles to the Island.

Mr. Cain said Louis Morales, doing business as Total Restoration of Weymouth, would complete the shear walls and First Choice Quality Painting Inc. would paint the exterior of the theatre.

The interior work will buttress walls that run the length of the building, which is structurally compromised and has been declared a safety hazard in the event of high winds.
