@Josiah Halverson starting one rehab ago I started pulling a permit for each job I do. I have always hired licensed electricians, plumbers and roofers with or without a permit though. Yes in my past life I didnt pull permits. Since you are somewhat familiar with my Sandy rehab, let me tell you exactly what I will have to do there that requires a permit. The roofer pulled his own permit for the roof. The window people will pull their own permit for the window replacement. The only new construction in this house is new kitchen and bath electrical circuits and new hard wired smoke alarms, moving washer hook ups-some cast iron replacing-new shower/tub valves and a new shower pan and frame two walls and add a door. The first step is plans. You will need to submit 2 sets of plans to the city and pull a permit. I have an electrician who is also a GC so he draws my plans and applies for the permit. Then I have my plumber pull a permit. Most areas will want a licensed plumber and electrician. Really not sure if a GC in Utah can do plumbing or electrical.
In Utah a handyman can be licensed and their work limit is $10,000.00. This is not just their scope of work but the total job weather the handyman does the work or not. So if the total job is over $10K a handyman should not be framing or anything that will be inspected.
Now right or wrong here is real life on the Sandy job. I left for a 10 day vacation and have only had the roof permit pulled. One is suppose to pull a permit before any work starts. I am not going to hold the job up so as you know, demo has started and now done, framing starts tomorrow then plumbing and electrical. A shower pan needs two inspections, the material that makes up the pan and the sand mix concrete that goes on top. I will have the framing, plumbing, shower pan and electrical done when I get back, and I choose not to have the first shower pan inspection. Ill pull the permit when I get back then get the inspections done. Typically because I use licensed electrians and plumbers and the GC reviews the handyman's framing, there shouldn't be an issue. There could be though. If the city gets mad they can charge double permit fees and make me rip the shower pan apart.
The point I hope you see is that with 3 days a week you should be able to manage the job just fine. Yes you will go nuts the first time, but you are a smart guy. Sometimes it is easier to just go for it. You should be able to pull a permit as an owner then hire licensed subs where required. As far as insurance goes, each licensed sub needs to give you proof of liability and workers compensation insurance. If you hire a GC don't assume he his getting the proper proof of insurance, see it for yourself. Most every worker even licensed handyman will have no insurance or maybe just liability. As a company you can pay workers compensations premiums on the workers you hire.
Maybe start marketing an see what happens. If an easy deal comes along start with that. If a harder one comes along sell it to me or partner with someone.
