I feel one side of my wall is a little too short, 5.5' facing a traffic street. almost 90% in my neighborhood extended it up to 3 more rows, which I want to do. Anyone know if I need city permit for this?

I saw several guys were working on doing this near my house. I stopped by to talked to them and found that walls in my neighborhood don't have rebars at all. Before putting in new block, 3 rows in top, he is putting in a verticle bar through each existing bocks from top to bottom. He is charging $500 every section include labor and material (around 10 blocks across, 3 blocks in vertible). Is this a reasonable price? Someone told me this old type of block is ugly but cost around $2/each block.
Any opinion?
