Avenue Portland, Orr?gon 97204 Dear Mr. Norman: In response to your letter of October 1.9, 1977, regarding the expansion of the First State Bank of Oregon located on S .W. Sandbur. g Street, as to whether we can accept the building ris type V-lhr. . construction, provided 'J' tj � .s the unprotected exterior wall be maintained at leasL 40 feet from any property line or building. z _� z ,3 After my telephone conversation with Mr. Ray Johnson, 4 s s 4 in the plans review section, Department of Commerce, Salem Oregon, I find that they have been approving exterior walls of type U construction as equal to one hour based on the exception in Section 2203 of the State Building Codo. Therefore, to be in uniformity with the Department of Commerce, I will accept the building as type V-1hr, con- struction. Also that three sides are sixty feet or more from property line, to maintain allowablii floor area. This approval is ;subject to the plans review by the Department of Commerce. Upon a site inspection it was noted that the existing building did not comply with the StatE Building Code as far as door hardware is concerned. permits for nE:w construction will be subject to entire building meeting all Code re- quirements. �Si n gP re 1.y E .T.'Jalden Building Official FTP:t,g CNGINfFRING REGISTRAI ION.
