3112.1 Scope and Purpose

STATE AMENDMENT
The purpose of section 3112 is to establish reasonable standards for the use of facilities designed for other purposes to be safely occupied temporarily as places of overnight accommodation. In this regard, 780 CMR is not intended to serve as a barrier to those seeking to assist individuals in need, but instead to offer a means to ensure that a reasonable degree of life safety is provided.
For purposes of section 3112, a temporary overnight shelter shall be defined as any building, facility, or space therein designed and used primarily as a church or house of worship for religious services or instruction or related activities which is owned or operated by a religious organization and qualified for exemption under 26 U.S.C. § 501(c)(3) (the Internal Revenue Code). The primary use of the building, facility, or space therein is for religious services or instruction but may, on occasion, provide temporary overnight accommodation to a limited number of individuals for a limited period of time as provided for section 3112. Other groups or organizations wishing to offer overnight accommodations in buildings designed and constructed for other purposes shall file an application for change of use in accordance with section 105.

Temporary overnight shelters, as addressed in section 3112, shall be classified as R-1 Use. Express administrative and technical requirements found in section 3112 shall override more general requirements found elsewhere in 780 CMR.
In order to operate a temporary overnight shelter, a temporary certificate of occupancy shall first be issued by the building official. Application for a certificate shall be made as follows:

  1. The application shall contain information demonstrating that the structure meets the following requirements:

    1. It has been issued a valid certificate of occupancy for its current use.
    2. It is or will be equipped with a functioning sprinkler system or is suitably protected by a hard-wired smoke and/or heat detection and alarm system, and a carbon monoxide detection system in accordance with section 3112.6, Table 3112.6; and sections 3112.7 through 3112.14.
    3. It contains adequate means of egress relative to the number of approved overnight occupants.
    4. It contains adequate emergency lighting and egress signage.
    5. It contains the necessary facilities in accordance with the applicable guidelines promulgated by the Massachusetts Department of Public Health.
    6. Attestation that the structure meets the requirements of 521 CMR: Architectural Access Board.
    7. Attestation that the location is equipped with a hard-wired land line phone or voice over internet protocol (“VOIP”) device for use in the event of an emergency.
  2. The application shall include the following:

    1. Zoning approval (if applicable).
    2. A plot plan (internet accessed satellite maps may be sufficient if properly labeled).
    3. A plan for compliance with the applicable guidelines promulgated by the Massachusetts Department of Public Health.
    4. A fire safety and evacuation plan. The plan shall include, but not be limited to:


      1. The identification of the anticipated nightly occupant load.
      2. A diagram of the bed and personal space layout.
      3. The identification of exits and aisles leading thereto.
      4. Outline of procedures for accounting for employees and occupants after evacuation.
      5. Outline of procedures for the evacuation of occupants with special needs.
      6. At time of activation, the head of the fire department shall be provided with the identification of the preferred and any alternative person responsible for reporting fires and other emergencies to the fire department.
      7. At time of activation, the head of the fire department shall be provided with a plan for assignment of personnel responsible for oversight of evacuation.
      8. A plan for training of employees relative to emergency evacuation.
    5. Identification of an on-site individual responsible for ensuring compliance with section 3112.
  3. Upon receipt of a completed application, the building official shall forward the application to the municipal fire chief and health official for their review. A site visit shall then be undertaken collectively by the building official, fire official, health official, the owner, and the applicant, or their respective designees. Said officials shall assess the suitability of the structure for issuance of a temporary certificate of occupancy and ensure the accuracy and efficiency of the documentation submitted in accordance with section 3112.3 items 1. and 2. Promptly after the site visit is completed, the building official shall either approve the application and issue the temporary certificate of occupancy, or deny the application, or approve the application and issue the temporary certificate of occupancy with conditions. The building official may condition the issuance of a certificate upon anything that he or she determines is necessary to ensure the safety of the occupants of the shelter and consistent with section 3112.1. Prior to taking action, the building official shall review the application with the fire chief and health official. The building official shall consider any recommendations made by the fire chief or health official with due regard for their concerns. However, the building official shall not issue any temporary certificate over the objection of the head of the fire department or the local board of health.
  4. Temporary certificates of occupancy shall not be issued for a period to exceed one year. Applications for renewal shall be reviewed in accordance with section 3112.3 items 1. through 3.
  5. If issued, the temporary certificate shall reflect the name of the organization it was issued to, the name of the party responsible for the operation of the shelter, the address, the issuance date, the expiration date, any conditions of issuance ordered pursuant to section 3112.3 item 3., and the maximum allowed occupant load.
  6. A temporary certificate of occupancy may be revoked by the building official at any time for a violation of any provision of section 3112, any violation of the applicable General Laws, or for any reason necessary to ensure the safety of the occupants of the structure. The terms of issuance of the certificate may similarly be modified. Any such action may be appealed to the Building Code Appeals Board in accordance with M.G.L. c. 143, § 100.

3112.4 Shelter Operation

STATE AMENDMENT
  1. The party responsible for the operation of the temporary overnight shelter shall notify the municipal building official and fire chief in writing at least 48 hours prior to each period of operation. The notification shall include a statement as to the anticipated number of days the shelter will be in operation and an estimate as to the number of individuals who will be in occupancy per night. Notification shall similarly be made within 24 hours after use of the shelter has ended.
  2. The temporary certificate of occupancy issued pursuant to section 3112.3 shall be conspicuously posted at the main entrance to the shelter.
  3. A document shall be posted, in a location approved by the municipal building official and the head of the fire department, containing an accurate number and names of occupants on a nightly basis and a copy of the evacuation plan referenced section 3112.3 item 2.d. Such document shall also contain the names of all workers and volunteers who are overseeing or assisting in the usage on a nightly basis. The shelter shall be set up and operated in accordance with the documentation submitted pursuant to section 3112.3 item 2. and any conditions mandated under section 3112.3 item 3.
Access to the shelter for purposes of ensuring compliance with section 3112 shall be granted upon request by the building official, fire chief, health official, police chief or their respective designees.
