This is a question about the ability of doing remodeling on one's own, compared to hiring licensed contractors.
I realize some remodeling/repairs require permits from your local township/city to be "legal" upgrades that are registered for benefits of resale and taxation.
Examples (and not sure if this includes a full list) would be adding/removing walls, replacing roof and/or shingles (permits for this is required in Flint, MI), electrical outlets (possibly needing to submit new electrical blueprints); I would assume that plumbing wouldn't need any town/city permits.
Also it is my understanding that only jobs requiring permits actually need any type of inspection. Is this correct/wrong? But the biggest question that I have for this is it possible to pull a permit for say electrical work, do the work yourself (making sure to follow all NEC regulations), and then have it inspected to be qualified to the town/city? As well as inspections of such type are done by certified masters of that field or is that a different certification to be an inspector?
