Building demolition takes a whole structure down and clears the debris from the site. We knock down commercial and industrial buildings, warehouses, garages and apartment buildings. Additions and outbuildings can come down on their own. MJ Masonry is a demolition contractor serving the South Shore, and whole-building knockdowns are the focus of our demolition work.
Property owners and developers around Greater Boston hire us for building demolition, and so do general contractors. We look at the building and the site first, then put the quote in writing. One house on its own lot falls under single-family house demolition.

A commercial demolition job takes the whole building down with our heavy equipment. On a steel-frame building, federal OSHA rules have the steel cut loose before a wall gets pulled over. The debris gets loaded onto trucks and hauled off the site. The written quote says where the job ends and what happens to the slab and foundation.
Some jobs take down only part of a property. An addition or an outbuilding can come down while the main building stays. The State Building Code has the permit's site plan show what comes down and what stays.
Some of the work around a knockdown belongs to other trades. An asbestos abatement contractor removes any asbestos before demolition starts. Other hazardous materials also come out first, through a separate contractor. If the building stays standing and only the inside goes, that is an interior gut-out.
OSHA's demolition rules call for an engineering survey before work starts. A competent person checks the structure for any chance of an unplanned collapse. Nearby structures where workers could be exposed get checked too. The rule calls for written proof that the survey was done.
Every gas, electric, water and sewer line gets shut off or capped outside the building line. Each utility company hears about it in advance. In an industrial building, pipes and tanks get checked for chemicals or fuel. Anything found gets tested and purged before demolition starts.
MassDEP, the state's environmental agency, wants written notice 10 working days before demolition starts. Only residential buildings with fewer than 20 units skip that notice. The same rules make the job answer for its dust, and wetting the area is one fix they name.
Every city and town issues its own demolition permit, and the paperwork differs from place to place. The State Building Code holds the work until the plans and a demolition schedule are approved.
In Boston, the Inspectional Services Department wants shut-off notices from every utility. It also asks for a Dig Safe reference number and MassDEP approval for hazardous materials. Under Article 85, buildings at least 50 years old go to the Boston Landmarks Commission first. So does every building Downtown or in Harborpark.
In Quincy, every demolition needs at least one Health Department walk-through. For the health sign-off, the building has to be clear of asbestos, PCBs, mercury and fuel oil. The city also asks for water or a misting agent on site before the work starts. Our guide to demolition permits in Massachusetts covers the steps in more towns.
