There is no action for the Construction Board of Appeals to take since this is not a public
hearing item.
Policy Context
The Building Official has authority to permit alternative materials, methods of
construction, or modifications to the code on a project-by-project basis when the
applicant has demonstrated that, while their design may not be prescribed by the code,
it still meets the minimum intent of the code.
California Building Code Section 104.11 states the following:
“Alternative materials, design and methods of construction and equipment.
The provisions of this code are not intended to prevent the installation of any
material or to prohibit any design or method of construction not specifically
prescribed by this code, provided that any such alternative has been approved.
An alternative material, design or method of construction shall be approved
where the building official finds that the proposed alternative meets all of the
following:
1. The alternative material, design or method of construction is satisfactory
and complies with the intent of the provisions of this code,
2. The material, method or work offered is, for the purpose intended, not less
than the equivalent of that prescribed in this code as it pertains to the
following:
2.1.Quality.
2.2.Strength.

Where the alternative material, design or method of construction is not approved,
the building official shall respond in writing, stating the reasons why the
alternative was not approved.”
DISCUSSION
Building Permit Number BLDG-2052-2022 (1322 Monterey Street)
The Building and Safety Division received an application for the use of an alternative
method of construction for a project located at 1322 Monterey Street (Attachment A).
The project is described as “Converting existing office duplex to residential duplex; &
site improvements.”
The conversion of this building into a residential duplex requires unit separation that
complies with the California Residential Code section R302.3. This section requires a
fire-resistance-rated wall assembly that extends from the foundation to the underside of
the roof sheathing. Section R302.3 reads as follows:
“R302.3 Two-family dwellings. Dwelling units in two-family dwellings shall
be separated from each other by wall and floor assemblies having not less
than a 1-hour fire-resistance rating where tested in accordance with ASTM
E119, UL 263 or Section 703.2.2 of the California Building Code. Such
separation shall be provided regardless of whether a lot line exists
between the two dwelling units or not. Fire-resistance-rated floor/ceiling
and wall assemblies shall extend to and be tight against the exterior wall,
and wall assemblies shall extend from the foundation to the underside of
the roof sheathing.”
The designer proposed an alternative method of construction to the provide the fire-
resistance-rating within the crawl space between the dwelling units. The conversion
from a B occupancy classification to an A occupancy classification required the
installation of a NFPA 13D sprinkler system. NFPA 13D does not require sprinklers to
be installed in crawl spaces. The designer provided a report (Attachment B) from a Fire
Protection Engineer that demonstrated an equivalent level of protection was provided by
extending the sprinkler system into the crawl space. The report also demonstrated that
the floor was designed to support the fire-resistance-rated demising wall above, which is
required by R302.3.1. This application was reviewed for compliance by the Chief
Building Official and the Fire Marshal.
Building Permit Number BLDG-1646-2023 (2125 Monterey Street)
The Building and Safety Division received an application for a code modification for a
project located at 2125 Monterey Street (Attachment C). The project is described as “28
ADDITIONAL HOTEL ROOMS & LOBBY/GYM/SPA/RESTUARANT BLDG; REVISION
TO PLAN OF 55 HOTEL ROOM”
Page 6 of 47
Item 5a
Section 422.2 of the California Plumbing Code (CPC) requires the restrooms in the
lobby to provide separate facilities for each sex. The applicant proposed a design which
modifies the code to allow gender-neutral multi-user restrooms (Attachment D). The
design demonstrated compliance with minimum fixture counts that are required for all
genders. The design includes full length walls for each toilet compartment and a shared
hand-washing area. There is also an additional family toilet facility. This additional toilet
facility was provided to ensure there was no reduction in Access since there would
otherwise be two wheelchair accessible stalls when separate facilities are provided.
Furthermore, the July 1, 2024 Supplemental code changes provides a new exception to
section 422.2 of the CPC. Exception 4, which becomes effective on July 1, reads as
follows:
“(4) Separate facilities shall not be required where rooms have fixtures
designed for use by all genders and the water closets are installed in
privacy compartments. Urinals, when installed, shall be located in a
privacy compartment or separate private area. Each compartment door
shall be lockable from the inside of the compartment, with a door locking
device that is readily distinguishable as locked from the outside of the
compartment. Privacy compartments and doors which are not full height or
floor to ceiling may be permitted by the enforcing agenc y.”

1 FIRE PROTECTION NARRATIVE
The intent of this report is to address the required fire protection at the crawl space for the 1322
Morro Street Residential Duplex Conversion in San Luis Obispo, CA. The approved plans for the
project call for the 1-hour fire rated separation wall between the two apartments to extend from
the foundation to the underside of the roof sheathing as required by CBC Section 708.4, which
states, in part:
708.4 Continuity.
Fire partitions shall extend from the top of the foundation or floor/ceiling assembly below
and be securely attached to one of the following:
1. The underside of the floor or roof sheathing, deck or slab above.
2. The underside of a floor/ceiling or roof/ceiling assembly having a fire-resistance rating
that is not less than the fire-resistance rating of the fire partition.
Exceptions:
1. Fire partitions shall not be required to extend into a crawl space below where the
floor above the crawl space has a minimum 1-hour fire-resistance rating.
Fire rated floor assemblies are required to meet CBC 420.3, specifically the following:
420.3 Horizontal separation.
Floor assemblies separating dwelling units in the same buildings, floor assemblies
separating sleeping units in the same building and floor assemblies separating dwelling or
sleeping units from other occupancies contiguous to them in the same building shall be
constructed as horizontal assemblies in accordance with Section 711.
Further, CBC 711.2.4.3 Dwelling units and sleeping units requires:.
Horizontal assemblies serving as dwelling or sleeping unit separations in accordance with
Section 420.3 shall be not less than 1-hour fire-resistance-rated construction.
Exception: Horizontal assemblies separating dwelling units and sleeping units shall be
not less than 1/2-hour fire-resistance-rated construction in a building of Types IIB, IIIB
and VB construction, where the building is equipped throughout with an automatic
sprinkler system in accordance with Section 903.3.1.1.
Then CBC 711.2.6 Unusable space, requires:
In 1-hour fire-resistance-rated floor/ceiling assemblies, the ceiling membrane is not
required to be installed over unusable crawl spaces. In 1-hour fire-resistance-rated roof
assemblies, the floor membrane is not required to be installed where unusable attic space
occurs above.
The horizontal assembly is required to meet the requirements for a 1 -hour fire-resistance-rated
assembly as the installed fire sprinkler system meets the requirements for a n NFPA 13D Residential
system not an NFPA 13 system as detailed in CBC Section 903.3.1.1.

As a cross reference the California Residential Code (CRC) provides similar direction for the fire
resistive constuction of horizontal assembiles separating dwelling units:
CRC R302.3 Two-family dwellings.
Dwelling units in two-family dwellings shall be separated from each other by wall and
floor assemblies having not less than a 1-hour fire-resistance rating where tested in
accordance with ASTM E119, UL 263 or Section 703.3 of the California Building Code.
Fire-resistance-rated floor/ceiling and wall assemblies shall extend to and be tight against
the exterior wall, and wall assemblies shall extend from the foundation to the underside of
the roof sheathing.
Exceptions:
1. A fire-resistance rating of 1/2 hour shall be permitted in buildings equipped
throughout with an automatic sprinkler system installed in accordance with
NFPA 13.
As noted above, the horizontal assembly is required to meet the requirements for a 1 -hour fire-
resistance-rated assembly as the installed fire sprinkler system does not meet all of the
requriements of an NFPA 13 system.
The approved plans for the project call for the 1-hour fire rated separation wall between the two
apartments to extend from the foundation to the underside of the roof sheathing as indicated
below:

The existing horizontal assembly doesn’t meet the requirements for a one-hour assembly,
therefore the required fire rated partion is required to extend into the crawl space. The existing
conditions are not suitable for the installation of a one-hour assembly within the crawl space so this
report proposes an alternate method of construction as allowed by CBC 703.3 for calculating fire
resistance and an alternate method of protection as allowed by CBC 104.11.

2 PROPOSED SEPARATION
METHOD
Because of the difficulty constructing the fire-rated wall in the crawl space below the raised floor
we are proposing to terminate the fire rated wall at the floor as follows:
CBC 703.2.2.3 Calculations in accordance with CBC 722
• 722.6 Wood Assemblies
• 722.6.2 Walls, floors and roofs
• 722.6.2.2 Table 722.6.2(1) indicates the time assigned to membranes on the fire
exposed side.
• 722.6.2.4 provides only for testing for the fire exposure from below.
CBC 722.6.2.1 Fire resistant rating of wood frame assembly is equal to the sum of the fire-resistance
time assigned to membranes:
Table 722.6.2(1) 15/32-inch wood structural panel bonded with exterior glue is assigned a fire-
resistance time of 10 minutes. The actual flooring assembly is 1/2” plywood over 3/4” T&G Oak
flooring over 1x6 diagonal sheathing over 2x floor joists @ 16” o.c. (This is not the exact wood panel
but the wood thickness is 2” total instead of required 15/32”).
Table 722.6.2(2) wood floor joists at 16” o.c. is assigned a fire-resistance time of 15 minutes.
Table 722.6.2(5) R-19 glass fiber mineral wool batt insulation is assigned a fire-resistance time of
15 minutes.
Page 16 of 47
1322 MORRO STREET DUPLEX CRAWL SPACE FIRE PROTECTION STUDIO DESIGN GROUP
Project No. C-0823-71 September 2023
Collings and Associates LLC Page 7
Total calculated fire resistance time ground-floor assembly is at least 35 minutes.
For reference, CBC Table 721.1(3) Item 13 -1.4 provides a time of 1/2 hour for a double wood floor over
joists spaced 16” o.c. Footnote “n” eliminates the drywall ceiling over the unusable crawl space.
Footnote “m” (a) defines a double wood floor. The existing flooring meets the definition except
there is no asbestos paper. However, there is an additional layer of 1/2” plywood instead.

Figure 711-1 from the 2015 International Building Code Handbook displays the crawl-space ceiling
omission. (Note: The 2016 CBC is based upon the 2015 IBC. Accordingly, we feel the rel evance of this
crawl space description is applicable to this project.)
Our proposed fire rated wall and floor assemblies are as indicated in Section ‘A’ and Section ‘B’
below:

Project No. C-0823-71 September 2023
Collings and Associates LLC Page 9
The calculated fire resistance of the existing floor assembly is 35 minutes. In order to achieve the
additional 25 minutes of fire resistance, our alternative method of protection is to extend the fire
suppression system into the crawl space as indicated on the following page:

The CBC recognizes the relevance of automatic fire sprinkler system protection within a crawl
space and the elimination of 1-hour fire-resistive construction between a Group R-3 occupancy and
the concealed space.
Our alternative method of protection is based upon the the installation of fire sprinklers within the
crawl space and 1-hour fire-resistive-construction equivalency noted as follows:
CBC Section 413.2 Attic, under-floor and concealed spaces.
Attic, under-floor and concealed spaces used for storage of combustible materials shall be
protected on the storage side as required for 1-hour fire-resistance-rated construction.
Openings shall be protected by assemblies that are self-closing and are of noncombustible
construction or solid wood core not less than 1 3/4 inch (45 mm) in thickness.
Exception: Neither fire-resistance-rated construction nor opening protectives are
required in any of the following locations:
1. Areas protected by approved automatic sprinkler systems.
2. Group R-3 and U occupancies.
This section does not specify NFPA 13 or CBC 903.1.1.1. Without the specific references for sprinkler
criteria, it is therefore, reasonable to assert that the automatic fire sprinkler system can be
designed and installed in accordacne with either NFPA 13, 13R, or 13D.
The combination of the existing floor calculated fire-resistance of 35-minutes and the equivalent
fire-resistance of 1-hour provided by the automatic sprinkler system exceeds the requirement of a
one-hour horizontal assembly. Therefore, the required fire partition wall does not need to be
extended through the crawl space.
Supporting hydraulic calculations and the fire sprinkler technical data sheet are attached to this
report.

3 CONCLUSION
In summary, the floor assembly provides at least 35 minutes of protection from a fire below. Fire
sprinklers are proposed in the crawl space under each of the two apartments to provide equivalent
protection of an additional 25 minutes to meet the one-hour fire separation required between
apartments.
Based upon the existing double wood floor over joists spaced 16-inches on center with 2-inches of
flooring on the surface, and the active fire suppression system, we believe the level of fire
protection meets or exceeds the perscriptive code requirements of CBC Chapter 7. For fire to burn
from one apartment to the other it has to burn through one floor assembly from above and then
encounters fire suppression from fire sprinklers and a 35-min. rated floor assembly between the
crawl space and the second apartment. The habitable spaces in the apartments are also fire
sprinkler protected per NFPA 13R.
We appreciate the opportunity to provide this fire protection analysis of the 1322 Morro Street
project.
If you have any questions or need further clarification please call our office.

The Model FR-RES Residential Pendent and Recessed Pendent Sprinklers are fusible link type automatic sprinklers. They
are durable and fast responding. The Model FR-RES is designed for residential occupancies and is perfect for use in
homes, hotels and other living quarters.
The Model FR-RES is to be used in wet pipe residential sprinkler systems for One- and Two- Family Dwellings and
Manufactured Homes per NFPA 13D; wet pipe residential sprinkler systems for Residential Occupancies up to and Including
Four Stories in Height per NFPA 13R; or, wet pipe sprinkler systems for the residential portions of any occupancies per
NFPA 13.
The Model FR-RES has a 4.9 (70.6 LPM/bar1/2) K-factor that meets the required residential flow rates with minimal residual
pressure, which allows for smaller pipe sizes and water supply requirements.
For extended installation flexibility, the Model FR-RES provides 1/2 inch (12.7mm) vertical adjustment with the D1 or D3
Recessed Escutcheon.
Notice: The heat sensitivity and water distribution design of Model FR-RES allows for an increased chance of residents
to escape or evacuate in case of a fire. However, residential fire sprinkler systems are not a substitute for fire safety
awareness or fire safety construction required by building codes.

OPERATION
The sprinkler assemblies fusible link is comprised of two link halves that are joined together with a thin layer of solder.
When the rated temperature is reached, the solder melts and the two link halves separate. This leads to the water flow to
be distributed on the affected fire area.

The herein stated rules for use and installation of Model FR-RES are provided by the manufacturer and must be strictly
implemented for safe and full results. Only the D1 or D3 Recessed Escutcheon, as applicable, is to be used for recessed
pendent installations. D1 Recessed Escutcheons are not listed for use with the 205°F heads. D3 Recessed Escutcheons
are required for the 205°F heads.
DESIGN CRITERIA
Notes
Residential Fire Sprinkler Systems should only be designed and installed by individuals who are completely familiar with
automatic sprinkler system design, installation procedures, and techniques.
Several criteria may apply to the installation and usage of each sprinkler. Consequently, it is recommended that the sprinkler
system designer review and develop a working understanding of the complete list of criteria prior to initiating the design of the
sprinkler system.
Questions concerning sprinkler installation and usage criteria, which are not covered by the following instructions, should be
submitted to your contracted company. Include sketches and technical details, as appropriate.
In some instances, the requirements of this document may concern specifications which are more stringent, and which take
precedence over those specified in NFPA 13, 13D, 13R or by the authority having jurisdiction.
The spray from the sprinkler is distributed radially outward and downward from the sprinkler deflector. Consequently, the
sprinklers must be located such that there will be no blind spaces shielded from spray by partitions, room dividers, overhangs
or other parts of the dwelling structure.
The number of sprinklers within each compartment (as defined by NFPA 13D, 13R, or 13) must be kept as few as possible while
observing all guidelines relating to obstructions and spacing.
The sprinkler must be secured in place by firmly fastening the sprinkler system piping to the structure. If the sprinkler is
not properly secured in position, reaction forces resulting from sprinkler operation could alter its orientation and its water
distribution pattern.
Obstruction to Water Distribution
Locations of sprinklers must follow the obstruction rules of NFPA 13, 13D and 13R for Residential Sprinklers.
General Service Conditions
The Model FR-RES must only be utilized in WET PIPE sprinkler systems.
Heat Source Criteria
Refer to NFPA 13D, 13R or 13 for the requirements relating to the prevention of possible activation of the Heat Responsive
Element of Model FR-RES, due to the exposure of a heat source other than an actual fire.

Precautionary Warnings for Corrosive Environments
Model FR-RES sprinklers should not be installed where they may be subjected to a corrosive environment including the
following:
Page 32 of 47
www.senjusprinkler.com Document No. U087144 • 01-26-2022 Page 4 of 8
1. Chlorine ion and Chloride environment
Stress corrosion cracking may be caused by exposure to environments with Chlorine ion and Chloride. Exposure to
this environment may result in sprinklers operating under Non-Fire conditions or Not Operating when exposed to an
actual fire.
2. Sprinkler system piping with Copper
Sprinkler systems should be constructed in compliance with the applicable standards and the requirements for
copper piping when copper piping is used in the sprinkler system. (Reference standards NFPA 13, ASTM B813, B828,
and CDA (Copper Development Association) – Solder Joint)
All residual flux must be removed from the interior and exterior of the copper piping by thoroughly flushing before
installation of the Sprinkler Heads. Otherwise, residues of flux may cause corrosion and/or leakage in the sprinkler
system.
Hydraulic Design Criteria
The minimum required sprinkler flow rates for systems designed to NFPA 13D or 13R are given in Table A as a function of
temperature rating and the maximum allowable coverage area. The sprinkler flow rate is the minimum required discharge
from the most hydraulically demanding sprinkler from each of the total number of “design sprinklers” as specified in NFPA
13D or 13R.
For systems designed to NFPA 13, the number of designed sprinklers is to be the four most hydraulically demanding
sprinklers. The minimum required discharge from each of the four sprinklers is to be the greater of the following:
• The flow rates given in Table A for NFPA 13D and 13R as a function of temperature rating and maximum allowable
coverage area.
• A minimum discharge of 0.1GPM/sq.ft. [4.07LPM/sq.m] over the “design area” comprised of the four most hydraulically
demanding sprinklers for the actual coverage area being protected by the four sprinklers.

INSTALLATION
The Model FR-RES must be installed in accordance with the following instructions:
NOTES
Do not use any sprinklers which have been subjected to potential mechanical damage. Do not use any sprinklers which show
deformation or cracking in either the Sprinkler or the Protective Cap.
Prior to installation, sprinklers should be maintained in the original cartons and packaging until used to minimize the potential for
damage to the sprinklers that could cause improper operation or non-operation.
The Protective Cap must remain on the sprinkler during installation. After the installation is completed, the Protective Cap must
be removed to place the sprinkler in service.
Use a torque of 7 to 14 ft·lbs (9.5 to 19.0 N·m) to achieve a 1/2 inch NPT sprinkler joint. If you exceed the recommended maximum
torque, this could result in damage to the sprinkler inlet, which may lead to leakage from the sprinkler.
Use only Spanner FR-S or Socket FR-H (or FR-H II) for installation of Model FR-RES sprinklers. Use of any other wrench or socket
is prohibited and may cause damage to the sprinkler.
Do not over or under tighten the sprinkler due to an inadequate adjustment of the D1 or D3 Recessed Escutcheon.
Re-adjust the sprinkler fitting to correct the position.
Sprinkler Spacing Criteria
The minimum spacing between sprinklers is 8 feet (2.4m). The maximum spacing between sprinklers cannot go beyond
the coverage area calculated by using the specific hydraulic factors. (Ref. Table A)
Installation Steps
Install Model FR-RES sprinklers by the steps and figures shown below. Use only D1 or D3 Recessed Escutcheons
with Model FR-RES sprinklers. (D1 Recessed Escutcheons are not listed for use with the 205°F heads. D3 Recessed
Escutcheons are required for the 205°F heads.) Use of any other recessed escutcheon is prohibited and may void the
warranty and approvals.
Model FR-RES sprinklers are only to be installed in the pendent position with the waterway perpendicular to the ceiling.
Step 1: Install the Inner Ring of the D1 or D3 Recessed Escutcheon over the sprinkler threads, as applicable. (Ref. Figure
3 and 4)
Step 2: Apply pipe-thread sealant to the threads. Begin hand-tightening the sprinkler into the sprinkler fitting in the
pendent position.
Step 3: Using the Socket FR-H (or FR-H II) or Spanner FR-S, tighten the sprinkler into the sprinkler fitting with a torque of
7 to 14 ft·lbs (9.5 to 19.0 N·m). (Ref. Figure 5) A 1/2″ drive ratchet (not included) is required for use with the Socket FR-H
(or FR-H II).
Step 4: Remove the Protector by hand. (Ref. Figure 6) Slide on the Outer Ring of the D1 or D3 Recessed Escutcheon over
the Sprinkler and push the Outer Ring over the Inner Ring until its flange comes in contact with the ceiling. (Ref. Figure 7)

The following instructions must be implemented for the maintenance and service of the Model FR-RES.
Notes
Wet pipe sprinkler systems must be maintained at a minimum temperature of 40°F / 4°C to prevent freezing and bursting of the
pipe and/or sprinklers.
Automatic sprinklers are not to be tested with a heat source. Operation of the heat responsive element can result.
Absence of the Outer Ring from the D1 or D3 Recessed Escutcheon, which is used to cover the clearance hole, can delay
sprinkler operation in a fire situation.
In preparation for maintenance of the fire protection system, permission to close the main control valve must be obtained from the
proper authorities, and all affected parties by this action, and must be informed before the maintenance session can commence.
Do NOT enclose any sprinklers within drapes, curtains, or valances.
Do NOT hang anything from the sprinklers.
Do NOT clean the sprinklers with soap and/or water, detergents, ammonia, cleaning fluids, or other chemicals.
Remove dust, lint, cobwebs, cocoons, insects, and larvae by gently brushing with a feather duster or gently vacuuming with a soft
bristle (i.e., dusting) brush attachment.
Exercise suitable safety precautions in the use and storage of highly flammable materials. The rapid rate of fire development and
spread of these materials can reduce the ability of the sprinkler system to aid in the control of a fire involving such hazards.
Leaking or corroded sprinklers must be replaced.
Page 36 of 47
www.senjusprinkler.com Document No. U087144 • 01-26-2022 Page 8 of 8
LIMITED WARRANTY
For details of warranty, refer to Sales Contract.
Automatic Sprinklers must be kept in a cool and dry place.
Automatic sprinkler must never be physically altered, such as painted, plated, or coated, once shipped from the factory. If the
sprinklers have been in any way modified, they must be replaced.
Great caution must be applied to prevent damage to the sprinklers at all stages - before, during, and after installation. Damaged
units because of dropping, hitting, over-tightening, or wrench slippage, must be replaced.
The Model FR-RES must only be replaced with pendent sprinklers which are listed for residential fire protection service and
which have the same nominal K-Factor, the same coverage area, and the same or lower flow ratings (as indicated under Table A
“Hydraulic Design Criteria”).
When remodeling, such as by adding false beams or light fixtures or changing the location of compartment walls, first verify that
the new construction will not violate the installation requirements of the applicable standards of NFPA. Alter the new construction
and/or the sprinkler system to suit the requirements of this document and the applicable NFPA regulations.
The owner is responsible for the maintenance of the sprinkler system, including inspection and testing of its compliance with
this document, as well as the standards of the National Fire Protection Association (e.g., NFPA 25), and the regulations of any
other authorities having jurisdiction. The owner should direct any questions regarding the above rules and regulations to the
installing contractors or the sprinkler manufacturer. It is recommended that automatic sprinkler systems be inspected, tested,
and maintained by a qualified Inspection Service in accordance with NFPA 25.

LEGISLATIVE COUNSEL'S DIGEST
SB 1194, Allen. Public restrooms: building standards.
Existing law requires a public agency, as defined, that serves the public or is open to the public and maintains
toilet facilities to make those facilities available to the public free of charge. Existing law, the California Building
Standards Law, establishes the California Building Standards Commission within the Department of General
Services. Existing law requires the commission to approve and adopt building standards and to codify those
standards in the California Building Standards Code.
This bill would authorize a city, county, or city and county to require, by ordinance or resolution, that public
restrooms constructed within its jurisdiction be designed to serve all genders, as specified, instead of complying
with the plumbing standards set forth in the California Building Standards Code. This authority will become
inoperative and be repealed on the date that standards that address all gender multiuser facilities take effect in
the California Building Standards Code.
Vote: majority Appropriation: no Fiscal Committee: no Local Program: no
