Deferral of any submittal items shall have prior approval of the building official. The architect or engineer of record shall list the deferred submittals on the plans and shall submit the deferred submittal documents for review by the building official.

Submittal documents for deferred submittal items shall be submitted to the architect or engineer of record who shall review them and forward them to the building official with a notation indicating that the deferred submittal documents have been reviewed and that they have been found to be in general conformance with the design of the building. The deferred submittal items shall not be installed until their design and submittal documents have been approved by the building official.

(e) Inspection and Observation Program. When special inspection is required by Section 23.06.130, the architect or engineer of record shall prepare an inspection program which shall be submitted to the building official for approval prior to issuance of the building permit. The inspection program shall designate the portions of the work to have special inspection, the name or names of the individuals or firms who are to perform the special inspections and indicate the duties of the special inspectors.

The special inspector shall be employed by the owner, the engineer or architect of record, or an agent of the owner, but not the contractor or any other person responsible for the work.

When structural observation is required by Section 23.06.140, the inspection program shall name the individuals or firms who are to perform structural observation and describe the stages of construction at which structural observation is to occur.

The inspection program shall include samples of inspection reports and provide time limits for submission of reports.

23.06.090 PERMIT ISSUANCE

(a) Issuance. The application, plans, specifications, computations and other data filed by an applicant for permit shall be reviewed by the building official or his designees. Such plans may be reviewed by other departments of this jurisdiction to verify compliance with any applicable laws under their jurisdiction. If the building official finds that the work described in an application for a permit and the plans, specifications and other data filed therewith conform to the requirements of this code and the technical codes and other pertinent laws and ordinances, and that the fees specified in Section 23.06.120 have been paid, the building official shall issue a permit therefore to the applicant.

When a permit is issued for required plans, the building official shall endorse in writing or stamp the plans and specifications "APPROVED." Such approved plans and specifications shall not be changed, modified or altered without authorizations from the building official, and all work regulated by this code shall be done in accordance with the approved plans.

The building official may issue a permit for the construction of part of a building or structure before the entire plans and specifications for the whole building or structure have been submitted or approved, provided adequate information and detailed statements have been filed complying with all pertinent requirements of this code. No building permit for construction of a superstructure shall be issued unless a complete superstructure application is made not later than 90 days after issuance of a foundation permit and a superstructure permit is taken out not later than 6 months after issuance of the foundation permit. For purposes of this section, the determination of whether a building or structure is a superstructure shall be made by the building official. The holder of a partial permit shall proceed at his own risk without assurance that the permit for the entire building or structure will be granted.

(b) Retention of Plans. One set of approved plans, specifications and computations shall be retained by the building official for a period of not less than 90 days from the date of completion of the work covered therein; and one set of approved plans and specifications shall be returned to the applicant and shall be kept on the site of the building or work at all times during which the work authorized thereby is in progress.

(c) Validity of Permit. The issuance of a permit or approval of plans, specifications and computations shall not be construed to be a permit for, or an approval of, a violation of any of the provisions of this code or the technical codes, or of any other ordinance of the jurisdiction. Permits presuming to give authority to violate or cancel the provisions of this code or of other ordinances of the jurisdiction shall not be valid.

The issuance of a permit based on plans, specifications and other data shall not prevent the building official from thereafter requiring the correction of errors in said plans, specifications and other data, or from preventing building operations being carried on thereunder when in violation of these codes or of any other ordinance of this jurisdiction.

(d) Expiration. Every permit issued by the building official under the provisions of the technical codes shall expire by limitation and become null and void, if the building or work authorized by such permit is not commenced within 180 days from the date of such permit, or if the building or work authorized by such permit is suspended or abandoned at any time after the work is commenced for a period of 180 days. Before such work can be recommenced, a new permit shall be first obtained to do so, and the fee therefore shall be one half the amount required for a new permit for such work, provided no changes have been made or will be made in the original plans and specifications for such work and provided further that such suspension or abandonment has not exceeded one year. In order to renew action on a permit over one year after expiration, the permittee shall pay a new full permit fee.

A foundation permit shall expire by limitation and become null and void, unless a complete superstructure application is made not later than 90 days after issuance of a foundation permit and a superstructure permit is taken out not later than 6 months after issuance of the foundation permit.

A permittee holding an unexpired permit may apply for an extension of the time within which work may commence under that permit when the permittee is unable to commence work within the time required by this section for good and satisfactory reasons. The building official may extend the time for action by the permittee for a period not exceeding 180 days upon written request by the permittee showing that circumstances beyond the control of the permittee have prevented action from being taken and that extension will not result in violation of this code or any other laws. Permits shall not be extended more than two times.

(e) Suspension or Revocation. The building official may, in writing, suspend or revoke a permit issued under the provisions of this code and the technical codes when the permit is issued in error or on the basis of incorrect information supplied, or in violation of an ordinance or regulation or the provisions of these codes.

23.06.100 DEMOLITION PERMIT CONDITIONS

(a) Demolition permits may be issued if at least one of the following is applicable:

(1) Demolition has been ordered by the building official because of major structural damage or a condition resulting in imminent or immediate danger to public health or safety; or

(2) A building permit or site development permit has been issued authorizing work to be performed which requires the prior removal of an existing structure to accomplish the new construction; or

(3) The city has determined that demolition is necessary in order to perform appropriate soil tests for a proposed project; or

(4) Demolition is required by the city as a condition of approval of a planning application under Title 27 or a subdivision under Title 26 of this code, and the application for the demolition permit complies with the time frame set in the condition of approval.

(5) The demolition involves a nonresidential structure of 3,000 square feet or less.

(6) The building official finds that:

(i) The structure is not habitable due to violations of Property Maintenance Code or the Building Standards Code as adopted by the City of San Mateo or local, state or federal laws; and

(ii) Substantial evidence has been provided that repair of the structure is not feasible. As used in this subsection "feasible" means capable of being accomplished in a successful manner within a reasonable period of time, taking into account economic, legal, social and technological factors. Evidence provided by the applicant may be independently reviewed by consultants hired by the City at the applicant's expense; and

(iii) Demolition of the structure would have a less significant effect on the neighborhood than allowing the existing dilapidated structure to remain.

A demolition permit shall not be issued pursuant to this subsection unless notice of the proposed demolition and appeal procedures is posted on the premises in a location visible from off-site at least fifteen (15) days before issuance of the demolition permit. Pursuant to Section 2.21.030, the building official's proposal to issue a demolition permit is appealable to the Community Relations Commission within the 15-day posting period by filing a notice of appeal with the City Clerk. If demolition is requested as part of a planning application pursuant to Section 27.68.020, the Planning Commission shall review the request as required by Section 27.68.020 prior to any action by the building official.

(7) The demolition involves a non-required accessory building.

(8) The demolition of structures where a master plan or specific plan has been approved for development of the site provided that (1) the building official receives written confirmation that the demolition is needed to facilitate the timely construction of new structures under the approved master plan, (2) the structures are substantially vacant, (3) there is written documentation from a lending institution that the project (at least in substantial part) is capable of being financed and the applicant is credit worthy.

(b) All demolition permits shall comply with the following conditions:

(1) If the site is a service station or listed on the Hazardous Waste and Substances Sites List (prepared pursuant to Government Code Section 65962.5), or if the City has any other substantial evidence that the site may contain hazardous wastes, the application for a permit must be accompanied by evidence that the soil has been inspected for contamination and, if contamination has been found, that a plan has been submitted to and approved by the San Mateo County Division of Environmental Health.

(2) The site shall be fenced when open holes in the ground exist, if required by the building official because of other hazards or to ensure maintenance of the site.

(3) All debris, weeds, and other nuisances shall be removed from the site, and the site shall be leveled unless requirements regarding hazardous wastes make leveling infeasible. If planting is not required by subsection 23.06.100(b)(4), and construction does not commence within 30 days after demolition, the soil shall be treated with a weed inhibitor approved by the City.

(4) If deemed appropriate, the City may require that the entire site be planted and maintained with a drought tolerant ground cover that will fully cover all exposed soil within six months of planting, or covered to a minimum depth of 2" with crushed rock.

(5) That the site be fenced according to code, or if deemed appropriate, the City may require that any driveway curb cuts not used be provided with bollards and chains, located and installed so as to prevent vehicular entry into the site.

(6) The applicant shall comply with all other conditions that may be attached by the building official to ensure maintenance of the site, including but not limited to vacant lot maintenance requirements contained in Chapter 7.48 of the San Mateo Municipal Code.

23.06.110 INSPECTIONS

(a) General. Construction or work for which a permit is required shall be subject to inspection by the building official and the construction or work shall remain accessible and exposed for inspection purposes until approved by the building official. In addition, certain types of construction shall have continuous inspection as specified in Section 23.06.130.

Approval as a result of an inspection shall not be construed to be an approval of a violation of the provisions of this code or of other ordinances of the jurisdiction. Inspections presuming to give authority to violate or cancel the provisions of this code or of other ordinances of the jurisdiction shall not be valid.

It shall be the duty of the permit applicant to cause the work to remain accessible and exposed for inspection purposes. Neither the building official nor this jurisdiction shall be liable for expense entailed in the removal or replacement of any material required to allow inspection.

A survey of the lot may be required by the building official to verify that the structure is located in accordance with the approved plans.

(b) Inspection Record Card. Work requiring a permit shall not be commenced until the permit holder or the agent of the permit holder shall have posted or otherwise made available an inspection record card such as to allow the building official conveniently to make the required entries thereon regarding inspection of the work. This card shall be maintained available by the permit holder until final approval has been granted by the building official.

(c) Inspection Requests. It shall be the duty of the person doing the work authorized by a permit to notify the building official that such work is ready for inspection. The building official may require that every request for inspection be filed at least one working day before such inspection is desired. Such request may be in writing or by telephone at the option of the building official.

It shall be the duty of the person requesting any inspections required either by this code or the technical codes to provide access to and means for inspection of the work.

(d) Approval Required. Work shall not be done beyond the point indicated in each successive inspection without first obtaining the approval of the building official. The building official, upon notification, shall make the requested inspections and shall either indicate that that portion of the construction is satisfactory as completed or shall notify the permit holder or an agent of the permit holder wherein the same fails to comply with this code. Any portions which do not comply shall be corrected and such portion shall not be covered or concealed until authorized by the building official.

There shall be a final inspection and approval of all buildings and structures when completed and ready for occupancy and use.

(e) Required Building Inspections. Reinforcing steel or structural framework of a building or structure shall not be covered or concealed without first obtaining the approval of the building official. Protection of joints and penetrations in fire resistive assemblies shall not be concealed from view until inspected and approved.

The building official, upon notification, shall make the following inspections:

(1) Foundation inspection. To be made after excavations for footings are complete and required reinforcing steel is in place. For concrete foundations, required forms shall be in place prior to inspection. All materials for the foundation shall be on the job, except when concrete is ready-mixed in accordance with approved nationally recognized standards, the concrete need not be on the job. When the foundation is to be constructed of approved treated wood, additional inspections may be required by the building official.

(2) Concrete slab or under-floor inspection. To be made after in-slab or under-floor building service equipment, conduit, piping accessories and other ancillary equipment items are in place but before any concrete is placed or floor sheathing installed, including the subfloor.

(3) Frame inspection. To be made after the roof, framing, fire blocking and bracing are in place and all pipes, chimneys and vents are complete and the rough electrical, plumbing, and heating wires, pipes, and ducts are approved.

(4) Lath and/or wallboard inspection. To be made after lathing and wallboard, interior and exterior, is in place but before plaster is applied or before wallboard joints and fasteners are taped and finished.

(5) Final inspection. To be made after finish grading and the building is completed and ready for occupancy.

(f) Required Building Service Equipment Inspections.

(1) General. Building service equipment for which a permit is required by this code shall be inspected by the building official. Building service equipment intended to be concealed by a permanent portion of the building shall not be concealed until inspected and approved. When the installation of building service equipment is complete, an additional and final inspection shall be made. Building service equipment regulated by the technical codes shall not be connected to the water, fuel or power supply, or sewer system until authorized by the building official.

(2) Operation of building service equipment. The requirements of this section shall not be considered to prohibit the operation of building service equipment installed to replace existing building service equipment serving an occupied portion of the building in the event a request for inspection of such building service equipment has been filed with the building official not more than 48 hours after the replacement work is completed, and before any portion of such building service equipment is concealed by permanent portions of the building.

(3) Other Inspections. In addition to the explicit inspections specified above, the building official may make or require other inspections of construction work to ascertain compliance with the provisions of this code or technical codes and other laws which are enforced by the code enforcement agency.

(4) Reinspections. A reinspection fee may be assessed for each inspection or reinspection when such portion of work for which inspection is called is not complete or when corrections called for are not made.

(5) This section is not to be interpreted as requiring reinspection fees the first time a job is rejected for failure to comply with the requirements of the technical codes, but as controlling the practice of calling for inspections before the job is ready for such inspection or reinspection.

(6) Reinspection fees may be assessed when the inspection record card is not posted or otherwise available on the work site, the approved plans are not readily available to the inspector, for failure to provide access on the date for which inspection is requested, or for deviating from plans requiring the approval of the building official.

(7) To obtain a reinspection, the applicant shall file an application therefore in writing upon a form furnished for that purpose, and pay the reinspection fee in accordance with the fee schedule adopted by this jurisdiction.

(8) In instances where reinspection fees have been assessed, additional inspection of the work will not be performed until the required fees have been paid.

(c) Investigation Fees: Work without a Permit.

(1) Investigation. Whenever work for which a permit is required by this code has been commenced without first obtaining a permit, a special investigation shall be made before a permit may be issued for such work.

Exhibit A

23.07.080 SECTIONS R902.1 AMENDED--ROOFING REQUIREMENTS.

23.08.100 SECTIONS 1505.1, 1505.1.3 AMENDED--ROOFING REQUIREMENTS,

FINDINGS:

Local Climatic Conditions - The weather patterns within the City of San Mateo are considered to be moderately affected by westerly winds that can average from 10-15 mph and gusts that can exceed 40 mph which are experienced almost year round. An average year's rainfall is approximately 22.95 inches, while summer conditions are hot and dry. These summer conditions create hazardous fuel situations that have caused grassland and brush land fires in recent years. Year round average temperatures range from 58 in the winter to 81 degrees during the summer, however high temperatures have ranged from 75 in the winter to 110 degrees in the summer. Low humidity, high temperatures and gusting winds can move a fire quickly in the hillsides and canyon areas of the City and can tax the capabilities of its urban designed fire department. Lower water pressure in these areas also affects the abilities to quickly suppress any fires.

Because of the unpredictable weather patterns, drought and water rationing can be expected, causing dry vegetation and hazardous fire conditions. Weather patterns can go to the other extreme with heavy rains creating higher fuel load in the hillsides. A heavy rain pattern would also impact a flood plain area located in the northeast portion of the City. This condition has the potential of causing additional barriers in this area when flooding blocks streets and underpasses.

The conditions described in this section make it reasonably necessary for the City to adopt the following ordinance section as modifications to the 2016 California Residential and Building Codes and these findings are specifically intended to satisfy the requirements of California Health and Safety Code Section 17958.7 in that regard: San Mateo Municipal Code Section 23.07.080 and 23.08.100.

23.07.110 SECTION R Section R602.10.3(3) and Table R602.10.4.4 AMENDED— prohibit the use of gypsum board and limit the use of Portland cement plaster as prescriptive wall bracing materials in Seismic Design Categories D 0 , D 1 and D 2

FINDINGS:

Local Geological Conditions – San Mateo is located near a vast array of fault systems capable of producing major earthquakes, including but not limited to, the recent 1989 Loma Prieta. Gypsum wallboard and exterior Portland cement plaster have performed poorly during recent California seismic events. The shear values for gypsum wallboard and portland cement stucco contained in the code are based on mono-directional testing. It is appropriate to limit the use of these products until cyclic loading testing are performed and evaluated.

23.08.120 SECTION 1705.3 Concrete Construction – Amended

23.08.130 SECTION 1905.1.7, ACI 318 Section 14.1.4 – Amended

FINDINGS:

Local Geological Conditions – San Mateo is located near a vast array of fault systems capable of producing major earthquakes, including but not limited to, the recent 1989 Loma Prieta. Results from studies after the 1994 Northridge earthquake indicated that a lot of the damages were attributed to lack of quality control during construction. The proposed amendment improves quality control during construction and therefore needs to be incorporated into the Code. Revise CBC Section 1705.3 exception No. 1 to allow special inspection not to be required for isolated spread footing where the structural design of the footing is based on a specified compressive strength, f'c, no greater than 2,500 psi. This proposed amendment is a continuation of an amendment adopted during the previous code adoption cycle.

23.16.020 SECTION 719.0 AMENDED--CLEANOUTS.

FINDINGS:

Local Geological Conditions – San Mateo soils are expansive in nature. These expansive soils create unstable conditions which increase the potential of breaks in sewer laterals. To maintain health and sanitary services, it is necessary to gain access and to periodically maintain public sanitary laterals. This is accomplished by the additional cleanout as required above.

The foregoing ordinance was adopted by the City Council of the City of San Mateo, State of California by the following vote:
