Selling a house with non-permitted patio cover

[Scott M.]

I've owned this house for ~6 years but live in a different state now and am planning to list it for sale in the next few weeks. 

About 5 years ago my father-in-law and I built a cover over the patio complete with shingles, two LED lights etc. I believe we did a decent job WRT 2x4 spacing etc. but at the time did not look up local building codes or apply for a permit. The house has since been painted and it looks professional / like it is part of the house.

Looking at it now the city code does require a permit for anything that attaches to the house, and I'm stressing hard about being so naive back then and not paying $50 for a permit.

What are my options here? Any advice?
