Force SVG Export using all <rect>

I'm trying to create an svg map of a storage unit facility using all rectangles, but when I export to svg, the resulting file contains some polygons <polygon> and rectangles <rect>.  All of the layers in Illustrator are rectangles, so I'm trying to understand why only some are being exported at <polygon> tags.  I need them to be <rect> tags for down stream processing.  Is there any way to force Illustrator to save them as <rect> tags?  Here's a snippet of the svg file:

<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 495.38 438.92">
  <defs>
    <style>
      .cls-1 {
        fill: #01cdcd;
      }
    </style>
