Because the increase is less than 10%, this <br />addition meets the requirements of the exception in Section 503.4 of the 2019 CEBC. Thus the existing structure <br />is permitted to remain unaltered. <br />Addt'l Seismic Weight <br />Estimated Roof Dead Load <br />Solar Dead Load <br />% Roof Covered <br />Equiv.
