Asbestos and Lead: Why Mold Demolition Waits Ten Working Days

Because a written asbestos survey has to come first on most buildings here, and where abatement is needed MassDEP must have the notification at least ten working days before it starts. In Cambridge 67.9 percent of housing units predate 1980, so this is the normal sequence rather than the exception.

The survey comes before the demolition, not after it

310 CMR 7.15(4) requires the owner or operator of a facility containing suspect asbestos-containing material to engage an asbestos inspector before any demolition or renovation, and to obtain a written asbestos survey report covering everywhere the work will breach: wall cavities, the areas above ceilings, and the spaces under and between multiple layers of flooring. Read that list again with a mold job in mind. Those three places are precisely where wet material hides and precisely where a remediation scope wants to cut. So the survey is not an unrelated piece of bureaucracy bolted onto the front of the work, it is a survey of the same square feet by a different discipline, and it has to exist as a document before anybody puts a saw into the wall.

The exemption almost nobody in this market qualifies for

There is a do it yourself exception, and it is drawn tightly enough to exclude most of the buildings around here. It covers the owner of an owner occupied single family residence doing the work themselves on non friable material alone, and 310 CMR 7.15(1) defines owner-occupied single-family residence to exclude rental property, multiple-family buildings and mixed use commercial and residential buildings. A two family, a three family or a rented single family therefore gets no exemption at all. Set that against the housing here: every city and town in this coverage area has a majority of its stock built before 1980, from Chelsea at 68.9 percent to Belmont at 87.3 percent. The combination of old buildings and small multi family ownership is why this gate applies to the normal job in this market rather than to an unlucky one.

Ten working days is not ten days

310 CMR 7.15(6)(a) requires a completed asbestos notification form and any applicable fee to be received by the Massachusetts Department of Environmental Protection at least ten working days before asbestos abatement begins, and it defines a working day as any day the Department is open for business. Count that out on a calendar with two weekends and a holiday in it and the real wait is comfortably over two weeks from the day the form goes in, which is itself after the survey and the laboratory result. Cambridge adds a local step on top: Inspectional Services lists an Asbestos Application for an Asbestos Removal Permit among its permit applications, so removal in this city needs a city permit alongside the state notification. Anybody promising that demolition starts within a fortnight on a pre-1980 building has not counted these days.

What counts as asbestos, and where it hides in an old house

310 CMR 7.15(1) defines asbestos-containing material as any material containing 1 percent or more asbestos by laboratory analysis, and names the usual suspects: pipe, boiler and duct insulation, floor and ceiling tiles, sprayed and troweled coatings, asphalt roofing and siding, and asbestos-containing paper. Now picture a Cambridge cellar after a leak, where 47.0 percent of the city's housing was built in 1939 or earlier and the median construction year is 1950. The wet material is often insulation on an old heating main, a stack of vinyl tile with the original layer still beneath it, or a troweled coating on a foundation wall. It is not that asbestos is likely everywhere. It is that the specific things that get wet in this housing stock are the specific things on that list, which is why the suspicion is reasonable and the survey settles it.

How the asbestos stage gets signed off

The close out is not the contractor's own opinion. 310 CMR 7.15(8) requires that after abatement an asbestos project monitor, and only a project monitor, inspects all surfaces in the work area for visible debris, and requires the asbestos contractor to clean repeatedly until no visible debris remains. That is a second pair of eyes with a defined role, and it is the model to hold in mind for the mold work that follows, where no equivalent is imposed by regulation. The housing code sets a comparable standard for the whole repair: 105 CMR 410.020 defines Compliance as not only correcting the violation in a workmanlike fashion but restoring all parts of the dwelling to the condition they were in before, with the appropriate official signing off wherever a building, plumbing or wiring permit was required. Finishing is a documented state, not a feeling.

Lead is a second gate on anything built before 1978

454 CMR 22.02 defines Target Housing as any housing constructed prior to 1978, other than housing for the elderly or people with disabilities where no young child resides, and zero bedroom dwellings. With 67.9 percent of Cambridge housing built before 1980, that catches most of the buildings a mold job happens in. Lead abatement is genuinely licensed in Massachusetts, unlike mold: 454 CMR 22.03 provides that no person or firm may enter into, engage in or work at the business of lead abatement without a Deleading Contractor license, and says engaging in the business includes advertising deleading services and bidding on work where most of the contract value is deleading, with limited exceptions for owners, owners' agents and low risk work by trained people. So on a pre-1978 building, cutting out wet painted plaster can pull a second licensed trade into a mold scope.

The permits, and the trap in pulling your own

Cambridge Inspectional Services states that anyone constructing, altering or demolishing a structure must obtain a building permit before work starts and post it prominently at the site, and that structures over 50 years old cannot be demolished without Cambridge Historical Commission approval, which reaches a great deal of this housing. Permits are issued to construction supervisors licensed by the city or the state, and also to homeowners doing work on one or two unit dwellings where they live, and the department warns those homeowners that they may be liable for contractors working on their property and are not eligible for protection under the Home Improvement Contractor law. MGL c.142A s.2 says the same thing from the statute side: obtaining permits is the contractor's obligation, and homeowners who secure their own permits are excluded from the Guaranty Fund provisions, which reach only pre-existing owner occupied buildings of one to four units in the first place. Pulling your own permit to save a fee is not a saving.

What still moves while the clock runs

The waiting period gates demolition, not drying, and that distinction is worth money. Water extraction, dehumidification, air movement and getting saturated absorbent contents out of the building are not renovation that breaches suspect material, so they can and should happen immediately while the survey and the notification run in parallel. Containment can go up. The scope can be written and priced against the survey's findings. What you should plan around is the working week itself: the city Noise Ordinance does not permit construction before 7:00 a.m., before 9:00 a.m. on Saturdays and holidays, or after 6:00 p.m., with no Sunday work, and a permit's work must start within six months of issue.
