Permit Application Information for Transfer Tax Rebates

  1. A separate permit application and plans are required for qualifying seismic strengthening work.
  2. Building permit applicants are required to state on the face of the permit application in the scope of work section “seismic safety work for transfer tax reduction”.
  3. Initially, “Plan Set A” submittals will be plan checked within 5 working days.  More complex submittals will be plan checked within 20 working days. These turnaround times will be evaluated and adjusted as necessary once the program is underway.
  4. Upon plan check approval, the front sheet of the plans will be stamped with the following statement: “Seismic strengthening work covered under this permit is eligible for the Transfer Tax Reduction provided in BMC 7.52.060 upon approval of final inspection”.
  5. Seismic work that facilitates future improvements or enlargement of existing spaces or upgrading other than seismic is not eligible for the transfer tax reduction.


Seismic Strengthening Work shall consist of one or more of the following:

  1. Repairing or replacing foundations – use prescriptive foundation requirements of CBC Chapter 18 (where applicable) or engineered plans
  2. Securing of chimneys or stacks – engineered plans required
  3. Removing of unreinforced masonry chimneys – plans required for replacement work
