Sorry, but it does matter.
Me too, until this happened to me.
Five years ago I had my entire driveway repaved, concrete. I hired a couple of young guys that had been in business for around eight years, small outfit, came with good referrals, at least the ones I could find at the time.
They kept putting off my project, nothing serious but with fall coming I wanted it done. I called one day on a Wednesday, they said they would start on the following Monday. Opps, no permit pulled, could I go get it because they were working out of town and wouldn't be able to do it. Ok, let's get this moving, I go down and pull the permit. Entire driveway, city sidewalk and apron at the road, all on the permit.
Job is finished the next week as promised, looks great. About one month later I notice the sidewalk portion is chipping, pitting and washing away with rain. The sidewalk and apron were from the same pour, the apron was fine, weird.
I call the guys that did the job. They shrugged their shoulders and said nothing they could do about it. I called the city, they came and looked and said "yup, the sidewalk has to be redone." They asked who did it, I told them, then they asked for the permit. I showed it to them. I was then told it was MY responsibility as my name was on the permit. If the contractor had pulled the permit the city would have gone after them to fix it.
I called an attorney friend, same answer as the city gave me. NEVER, NEVER pull a permit unless you are willing to stand by the work as if you did it yourself.
It cost me an addition $1500 to fix a twenty foot sidewalk as the city gave me 30 days to do it. I couldn't find anyone in that time frame so the city came and did it and that was their charge for it.
