This data shall be submitted to the planning commission, who shall determine compatibility of the proposed installation with the neighborhood, and who shall, within forty days of submission to it of the data, make a determination as to compatibility of the mobile home with the neighborhood, and report its findings to the building official. If the findings recommend approval of issuance of the building permit, the building official shall issue the permit, subject to any other conditions applicable to construction in an R-1 or R-2 districts.
