504B.2 Program Implementation.

504B.2 Program Implementation. The requirements stated in Section 504B.1 above shall be accomplished by submitting to the Building Official the following:

504B.2.1 Inventory form. The owner is required to submit to the Department, within the time limits set forth in Table 5B-A, a properly completed inventory form, signed and sealed by the owner’s civil or structural engineer or architect. See San Francisco Building Code Section 110A, Table 1A-S for the applicable fee for the review of the inventory form. A failure to respond within the time limits set forth in Table 5B-A is a violation of this code.

504B.2.2 Risk assessment.

504B.2.2.1 General. When filling out the required information on the inventory form, the owner’s architect or civil or structural engineer shall assign to the building a relative level of risk depending upon the occupancy, soil conditions at the site and the density of the population exposed.

504B.2.2.2 Level of risk assigned.

1. Level 1 buildings are buildings containing Groups A Occupancies with an occupant load of 300 or more; or Group E Occupancies, and those buildings greater than three stories in height which are located on poor soil.

2. Level 2 buildings are all non-Level 1 buildings which are located on poor soil in the Downtown, North of Market/Civic Center, South of Market, South of Market Residential and Chinatown Unreinforced Masonry Building Study Areas as delineated on Figure 5B-1.

3. Level 3 buildings are buildings in the above areas which are not located on poor soil and buildings located on poor soil outside the above areas.

4. Level 4 buildings are all other unreinforced masonry bearing wall buildings.

504B.2.3 Engineering reports. The owner shall engage a registered civil or structural engineer or licensed architect to prepare an engineering report on the building when:

1. An owner desires to demolish a qualified historical building or any building containing a nonexempt Group R Occupancy rather than retrofit the building, and a report is requested by the Building Official or the Building Official of the Planning Department; or

2. The Bolts-plus level of strengthening is proposed; or

3. Strengthening to comply with the State Historical Building Code is proposed; or

4. The owner believes the building complies with Chapters 5B and 5C without any further alteration.

The engineering report shall detail applicable retrofit requirements of the least restrictive retrofit procedure for which the building qualifies. The required retrofit measures shall be developed schematically, and a conceptual construction cost estimate shall be included. If the Bolts-plus level of strengthening defined above and described in Exception 1 to Section 509C.2 is proposed, the necessary measures for compliance with the Special Procedure of Section 511C shall also be designated, and a second cost estimate for this option shall also be included in the report. If the engineering report demonstrates that no deficiencies exist, and the report is approved by the Department, the structure will be considered to conform to the requirements of this chapter. Except as noted in 1. above, the report shall be submitted not later than the date when the application for the building permit to either strengthen or demolish the building would otherwise be required. The format and content of the engineering report shall comply with the provisions of rules and regulations to be issued by the Building Official pursuant to San Francisco Building Code Section 104A.2.1 after consultation with the Seismic Safety Retrofit Bond Program Board. See San Francisco Building Code Section 110A, Table 1A-S for the applicable fee for the review of the engineering report.

504B.2.4 Application for building permit. The owner shall submit to the Department an application for a structural alteration permit accompanied by structural plans, specifications and calculations for the proposed mitigation solution or a permit application to demolish the building. Time limits for submission of the application and for permit processing and approval are established in Table 5B-A.

504B.2.5 Commencement and completion of construction. Construction work shall commence and a Certificate of Final Completion and Occupancy or final inspection of work under a demolition permit shall be obtained within the time limits set forth in Table 5B-A.

5 04 B.2.6 Transfer of title. No transfer of title shall alter the time limits for compliance set forth in Table 5B-A.
