follows:
AF101.1
General. This
appendix contains minimum requirements for new construction in the high radon
potential counties as listed in Table AF101(1) regardless of the radon levels
at the site. These requirements are intended to provide a passive means of
resisting radon gas entry and prepare the dwelling for post-construction radon
mitigation, if necessary.
See Figure AF102. Active
construction techniques, rather than passive techniques, shall be permitted to
be used where approved.
Alternatively, the passive system requirements of ANSI/AARST
Standard Designation #CCAH: Reducing Radon in New Construction of One
& Two Family Dwellings and Townhouses, 2013 may be used for new
construction in Zone 1, or approved equal system.
Irrespective of which approach is used, no testing is required
as follows:
1. for the radon levels at
the site prior to construction;
2.
for the radon control system when completed; or
3. in the building after completion of the
project.
Therefore, such testing shall not be a condition of issuing a
certificate of occupancy.
AF102.1 Revise the definition of
"GAS-PERMEABLE LAYER" as follows:
GAS-PERMEABLE LAYER. A gas-permeable layer shall
consist of one of the following:
1. A
uniform layer of clean aggregate that is not less than four inches (102 mm)
thick. The aggregate shall consist of material that will pass through a two
inch (51 mm) sieve and be retained by a ¼-inch (6.4-mm) sieve.
2. A uniform layer of sand (native or fill)
that is not less than four inches (102 mm) thick and that is overlain by a soil
gas collection mat or soil gas matting installed in accordance with the
manufacturer's instructions. The soil gas mat or matting shall be designed for
this purpose and condition, and have the capacity to freely transport soil
gases to the collection point from the most remote area.
AF103.2.2 Revise the subsection as

AF103.2.2
Sumps. Sumps
open to soil or serving as the termination point for subslab drain tile loops
shall be covered with a gasketed or sealed lid. Sumps used as the suction point
in a sub slab depressurization system shall have a lid designed to accommodate
the vent pipe. Sumps used as a floor drain shall have a lid equipped with a
trapped inlet. Drainage systems that lead outside the foundation walls shall be
isolated or trapped so as not to short-circuit the depressurization
system.
AF103.3.1 Revise
the subsection as follows:
AF103.3.1
Soil-gas-retarder. The soil in basements and enclosed crawl spaces
shall be covered with a soil-gas-retarder. The soil-gas-retarder shall be
lapped not less than 12 inches (305 mm) at joints and shall extend to
foundation walls enclosing the basement or crawl space. The soil gas-retarder
shall fit closely around any pipe, wire or other penetrations of the material.
Punctures or tears in the material shall be sealed or covered with additional
sheeting. The membrane shall extend upward six inches and shall be sealed to
the perimeter footing or wall with an ASTM C290 class 25 or higher sealant or

the soil-gas-retarder and be connected to a three-inch minimum vertical vent
pipe. The vent pipe shall extend through the conditioned space of the dwelling
and terminate not less than 12 inches (305 mm) above the roof in a location not
less than ten feet (3,048 mm) away from any window or other opening into the
conditioned spaces of the building that is less than two feet (610 mm) below
the exhaust point. The horizontal legs of the "T" fitting shall connect to two
five-foot long pieces of four-inch diameter perforated pipe laid horizontally
in a 50 in2 bed of gravel, filled with the same
gravel as used in the gas-permeable layer.
AF103.4.2 Revise the subsection as follows:
AF103.4.2
Soil-gas-retarder. A
soil-gas-retarder shall be placed on top of the gas-permeable layer prior to
casting the slab or placing the floor assembly. The soil-gas retarder shall
cover the entire floor area with separate sections lapped not less than 12
inches (305 mm) and shall extend upward six inches and be sealed to the wall
with an ASTM C290 class 25 or higher sealant or equal. The soil-gas-retarder
shall fit closely around any pipe, wire, or other penetrations of the material.
Punctures or tears in the material shall be sealed or covered. Under-slab
insulation, if used, shall be placed on top of the

Appendix J: EXISTING BUILDINGS AND STRUCTURES
(Adopted as modified herein)
AJ101.1 Revise the section as follows:
AJ101.1
General. The purpose of
Appendix J is to encourage the continued use or reuse of
legally existing buildings and structures. The provisions of
Appendix J
are intended to permit work in existing buildings that is consistent
with the purpose of 780 CMR
51.00. Compliance with these provisions shall be
deemed to meet the requirements of 780 CMR
51.00.
Features of existing construction which do not meet the
requirements of 780 CMR 51.00 for new construction shall be presumed to have
met the regulations, codes or laws in effect at the time of construction or
alteration and, if so, shall be deemed to be existing nonconforming. Unless
stated otherwise, nothing in Appendix J shall require the
upgrading or replacement of any existing nonconforming feature or component of
an existing building, provided the feature, component or system is in
serviceable condition. Components or features of an existing building which, in
the opinion of the building official, are dangerous, unsafe, damaged,
significantly deteriorated or which otherwise present a threat to occupants or
to public safety shall be remediated in accordance with 780 CMR 51.00.
Any new building system or portion thereof shall conform to 780
CMR 51.00 for new construction to the fullest extent practicable. However,
individual components of an existing building system may be repaired or
replaced without requiring that system to comply fully with 780 CMR 51.00
unless specifically required by Appendix J.
For compliance of work governed by other codes, including the
specialized codes, see section R101.4.
AJ101.1.1

AJ102.1 Replace the phrase "mechanical or
plumbing system" with "system controlled by this code"
AJ102.3 Replace as follows:
AJ102.3
Smoke, Heat, Carbon Monoxide
Detection and Alarm Systems. When one or more sleeping rooms are added
or created in existing dwellings, the entire existing dwelling shall be
provided with smoke detectors, heat detector and carbon monoxide detectors
designed, located and installed in accordance with the provisions for new
construction, as applicable. If a garage is created under an existing dwelling
or attached to an existing dwelling, a heat detector, conforming to the
requirements of the code for new construction shall be installed in the garage;
such requirement is not applicable for detached garages (
see
Chapter 3).
If the dwelling undergoes complete reconstruction such that all
walls and ceilings are open to framing, then the entire existing building shall
be provided with smoke detectors, heat detector and carbon monoxide detectors
designed, located and installed in accordance with the provisions for new
construction.
In an existing two-family dwelling, if one or more sleeping
rooms are added or created in only one of the two dwelling units, the dwelling
unit acquiring new sleeping rooms shall be provided with smoke detectors, heat
detector and carbon monoxide detectors, as applicable, designed, located and
installed in accordance with the provisions for new construction.
In an existing two-family dwelling, if, during a
repair/reconstruction event, one or more sleeping rooms are added or created in
both of the two dwelling units, the entire building shall be provided with
smoke detectors, heat detector and carbon monoxide detectors, as applicable,
designed, located and installed in accordance with the provisions for new
construction for two-family dwellings.
Note 1. It is the intention of this code to
require that all required smoke alarms and required CO alarms be interconnected
by hard-wire methods or acceptable wireless methods per the interconnection
requirements of NFPA 72; additionally, required heat detectors are either to
activate sounders or be compatible with the smoke alarm system so that heat
activation of the heat detector operates a sounder or the smoke alarms of all
interconnected smoke alarms sound if heat is detected by the interconnected
heat detector. Where combination smoke/CO alarms are utilized, such are to be
interconnected and fire alarm signals have precedence over CO alarm in
accordance with the requirements of NFPA 720.
Note 2. CO detector requirements for existing
R-uses are also governed by
527 CMR 31.00: Carbon
Monoxide Alarms and the Board of State Examiners of Plumbers and Gas
Fitters at 248 CMR.
AJ102.7.1 Add subsection:

as applicable, and those of the appliance manufacturer shall be satisfied. If
the appliance is a solid fuel-burning appliance, the chimney shall be relined
to satisfy requirements both of the code for new construction and those of the
manufacturer, as applicable.
AJ102.11 Add subsection:
AJ102.11
Latent Conditions. When
latent conditions are observed and which are determined by the licensed
construction supervisor, the owner or the
building official to
be dangerous or unsafe, or when a component or system is determined to be
unserviceable, said conditions shall be corrected in accordance with applicable
provisions of this code. A building
permit shall be obtained
or the building
permit shall be amended in accordance with the
provisions of Section R105 in order to reflect the necessary required work and
the approval shall be obtained from the
building official
prior to commencement of the corrections.
Exception. If the public safety so warrants, the
building permittable corrective actions are permitted to be made prior to
amending the building permit application, providing that the
building official is notified in writing within 24 hours of
actions taken pursuant to this exception. This exception shall not be construed
as to authorize constructive approval nor set aside the requirements to amend
the permit application, nor shall the authority of the
building official to enforce this code be abridged. Such
corrective actions shall be documented by the construction supervisor or the
owner and submitted to the building official within 48 hours
of the completion of the action under this exception. Such corrective work
shall not be concealed until the building official has
inspected and approved the work.
AJ102.12 Add subsection:
AJ102.12
Existing non Conforming Means
of Egress. The following conditions, when observed by the
building official, and believed shall be cited, in writing as
a violation. Said citation shall order the abatement of the non conformance and
