Subject: Masonry Calculations for Residential Construction
On March 1, 2004, Ordinance 3637 was passed by City Council that all main buildings in AG, R and D districts platted after that date shall be of fire-resistant construction, having at least 90% of the total exterior walls - excluding doors and windows - constructed of brick, stone, concrete block, stucco or other masonry or materials of equal characteristics.
With passage of this ordinance, the method in which masonry requirements are calculated for new subdivisions with approved filed plats as of March 1, 2004, has changed. The calculations are taken from the foundation to the roofline for one or multiple-story structures. In order to decrease the amount of time necessary for plan reviews, we request all plans be submitted having the masonry calculations clearly showing compliance with Ordinance 3637.
