(A) Every dwelling unit and every rooming house with shared cooking facilities must have sufficient space for storing, preparing, and serving food in a sanitary manner. Within this room, the owner must provide:
The owner of any dwelling in which a toilet, wash basin, shower, or bathtub is to be shared by the inhabitants of more than one dwelling unit or one rooming unit is responsible for and shall exercise good care in keeping that toilet, wash basin, shower, or bathtub clean and sanitary, including cleaning the fixture at least once every twenty-four hours.
The board of health may authorize the construction or continued use of any privy or chemical toilet if it decides that it will not (a) endanger the health of any person; or (b) cause objectionable odors or other unnecessary annoyance. When licensed, a privy or chemical toilet may qualify as a toilet under 105 CMR 410.150(A) subject to written authorization of the board of health in compliance with Title 5 of the State Environmental Code (see CMR 410.840). A privy must be at least 30 feet away from any sleeping or eating area, as well as any lot line or lane.

Bathroom exhaust fan ductwork

Bathrooms are damp, odorous spaces that are often enclosed and unventilated. Smells are merely inconvenient. Moisture, on the other hand, is the real issue because it can lead to dangerous mold and mildew, which can eat away at your walls, ceiling, and trim. Bathrooms can only benefit from an exhaust venting system of some kind. But which sort do you need, and what does your town’s or city’s bathroom exhaust fan venting code say about it?
The problem of transferring odor- and moisture-laden air from the bathroom to the outside is addressed in the bathroom code. Surprisingly, some building codes do not require bathroom fans. Different municipalities have different criteria, but some don’t need exhaust fans at all. Bathroom ventilation is expected in those areas, but it can come from a window or a fan, depending on your preference.
The building code is a model code that each group will adopt and change to meet its unique needs. As a result, you’ll need to consult with your city or county’s planning and permitting department to learn about bathroom fan code specifications. Also, your area’s code numbering can vary from those mentioned here.

Massachusetts building codes for bathroom remodeling

Massachusetts finished upgrading its base and stretch energy codes on July 19, 2016. The 8th edition of Massachusetts’ building codes has been revised to incorporate the 2015 IECC / ASHRAE 2013, which will go into effect on January 1, 2017. State revisions to the base energy code (residential and industrial, to be published) are included in the adopted code, as well as a revised stretch energy code (adopted as is). When the state adopts the entire 2015 I-code set as its 9th edition, amendments not included in this 8th edition, such as the clean energy preparation requirements, will be reconsidered.
Massachusetts would save a considerable amount of money on energy costs as a result of upgrading its commercial and residential building energy standards in compliance with federal legislation, expected to be on the order of about $144 million per year by 2030.

Loop vents for venting islands in your kitchen

But, after they listed a mechanical permit, I’ve stopped doing them entirely. And that makes me happy. When it comes to the permit, the carpenters on my jobs are usually the ones who mount the vent. I’m not sure whether they do it themselves or whether the plumbers check it. For the most part, it hasn’t been a problem for me.
I’m not looking for an excuse to mount the duct; rather, I’m looking for a reasonable reason not to. Some towns state categorically that they cannot, while others state that there is an exception to the law. When there is no HVAC mechanic on the job, I work with a general contractor who insists that I be the one to mount the ventilation duct.
Who is responsible for providing and installing the fan? If that’s the case, I can see how you’d be expected to finish the installation. Saying you no longer supply fans but would be able to wire one once it’s in place is a simple way around this.
This is an example of an absurd law. Now, I understand that an HVAC technician is less likely to do a shoddy job on the vent work because he most likely has all of the necessary equipment and materials. Most electricians I’ve met or seen apply a few wraps of cheap duct tape and call it a day. However, there’s no reason why an electrician shouldn’t be able to do this job. We have the mechanical capabilities to do it.
