Article 2. Structural And Material Requirements Of Community Mausoleums And Columbariums of California Health And Safety Code >> Division 8. >> Part 5. >> Chapter 5. >> Article 2.
Every mausoleum or columbarium shall be designed and
constructed to conform to the earthquake provisions of the Uniform
Except as otherwise provided in this chapter, all materials
used in the construction, ornamentation, or embellishment of
mausoleums or columbariums shall be incombustible. This section shall
not apply to crypt vents, temporary openings or partitions, interior
doors, fixtures, furniture, or furnishings.
All structural framework shall be of cast-in-place reinforced
concrete, or of structural steel sections, or of concrete over metal
decking; provided, however, all footings, bearing walls, floor slabs
and roofs shall be of cast-in-place reinforced concrete or of
concrete over metal decking only. All structural framework shall be
designed and constructed in accordance with the Uniform Building
All floors shall be designed and constructed for a live load
of not less than 100 pounds per square foot.
Footings shall be designed and constructed to conform to the
requirements of the Uniform Building Code or specifications of a
licensed geotechnical engineer.
Floor slabs placed on earth shall be constructed of
reinforced concrete designed by a licensed structural or civil
engineer to include control joints at appropriate intervals to
minimize cracks as well as appropriate vapor and moisture barriers as
specified by a licensed geotechnical engineer.
Where any wall is constructed against a bank of earth, rock,
or other porous material, or where crypts are adjacent to an outside
building wall below grade, the wall shall be adequately waterproofed.
Before backfilling, a waterproofed wall shall have a protection
board placed against it to prevent damage to the waterproofing during
Except as provided in Section 9633, all crypt walls and crypt
floor slabs shall be constructed of cast-in-place, reinforced
concrete; crypt walls shall conform to structural design but shall be
not less than three and one-half inches in thickness, and crypt
floor slabs shall be not less than three inches in thickness.
Horizontal and vertical partitions separating crypts
comprising companion crypts or a nest of crypts entered through a
single crypt opening may be constructed of precast reinforced
concrete; provided, the horizontal partitions are not less than one
and one-half inches in thickness and the vertical nonbearing
partitions are not less than one inch in thickness, and vertical
partitions bearing any load are not less than three inches in
thickness, and provided the crypt walls enclosing the nest of crypts
are constructed as required in Section 9632. Crypts shall be vented
at roof level of the structure, and vents shall continue to a gravel
filled trench below the floor of the bottom crypt to provide adequate
circulation of air. Nonstructural horizontal and vertical partitions
separating columbarium niches may be constructed of precast
reinforced concrete or other incombustible material.
Each crypt, including each crypt in a companion crypt or in a
nest of crypts referred to in Section 9633, shall be designed for a
total live load of 600 pounds.
(a) All individual crypt openings shall be sealed with a
solid panel of precast concrete, not less than 1 1/2 inches thick,
fiber reinforced cement board not less than 7/16 inch thick, or other
incombustible material that meets all of the following requirements:
(1) A minimum density of 80 pounds per cubic foot.
(2) A minimum modulus of rupture of 270 pounds per square inch.
(3) A minimum compressive strength of 2500 pounds per square inch.
(4) A rating that conforms to Underwriters Laboratories fire
hazard class 1.
(b) All panels shall be securely set in with a high quality,
nonflammable, resilient, and nonhardening urethane, silicone base, or
other appropriate sealant for permanent sealing after interment is
made in the crypt. Seal panels shall be set independent of crypt
All marble floors shall be constructed on a bed of mortar or
mastic placed on the floor subslab, with an approved additive to
All interior or exterior veneers shall be of stone, cast
stone, granite, travertine, or marble, or other material allowed in
the Uniform Building Code for type I construction. Cast stone shall
meet all requirements for cast stone set forth in the Uniform
Material for exterior trim, including exterior crypt and
niche fronts, shall be travertine, serpentine marble, or grade A
exterior type marble or granite, only.
Joints shall be of uniform thickness and when mortar is used
it shall be raked out as work progresses and on completion of
installation joints shall be brushed, thoroughly cleaned, wet and
carefully filled and pointed.
Grout used for joints and pointing shall conform with the
requirements of the Uniform Building Code.
Masonry veneer shall be attached to the supporting wall in
accordance with the requirements of the Uniform Building Code.
All base, architraves, wainscoting and all other vertical
work other than crypt fronts shall be securely anchored in place with
rods, clips, or other suitable anchoring devices of materials as
specified in Section 9643. All clips shall be countersunk into the
joint surface and set in nonstaining cement or epoxy.
All interior and exterior fastenings for hangers, clips,
doors, and other objects shall be of copper base alloy, aluminum,
copper or stainless steel of adequate gauges and shall be installed
to meet or exceed the seismic requirements of the Uniform Building
All exterior materials used for doors, window frames,
skylights, gutters, downspouts, flashings or embellishment shall be
of copper, copper base alloy, aluminum, stainless steel, or other
corrosion resistant material of gauges structurally determined.
In the event that during a national emergency, as proclaimed
by the Governor for purposes of this section, none of the materials
listed in Sections 9643 and 9644 are obtainable, the department may
permit the use of galvanized iron or other durable materials.
Roofs shall be constructed of cast-in-place reinforced
concrete, and any roof covering shall be "Fire Retardant" in
conformity with the requirements of type I construction.
All skylight frames shall be fabricated in conformance with
structural requirements, and shall contain wire glass, tempered
glass, or plastic of comparable strength and durability.
