My career in the residential building trades began by painting one room and it took off from there. That was almost 16 years ago and during that time I’ve demoed and installed everything in a house that you can imagine. I’ve taken and passed the contractor’s exam and without having worked for any company or any one person that would be able to support a class C contractor application I can’t apply for that permit.
My class D permit applications have been denied because I can’t show 24 consecutive months of working within specific fields for which my applications were submitted, despite testimonies from customers. No one behind the counter is willing to help or advise me and in fact have been curt and rude. Has anyone out there experienced any similar problems in getting a permit? Why is the city and county of Denver so hard to deal with?
