Is there anyone that has successfully converted a SFH to a duplex in the Birmingham, AL area that is willing to share their costs for electrical/plumbing/gas work and separately metering?

Will b doing renovation myself and boyfriend who does plumbing, heating and construction.

Things that will not matter are lighting and plumbing fixtures.

But I'm afraid of too picky inspections and that I'll need to remove all walls, ceiling and floor (basement has kind of inside crawl space - elevated floors for plumbing I guess)I'll do some apparent work anyways: add vents for bathroom/dryer/microwave, insulate and enclose the furnace (at least from thr bedroom), check for gfci/arc breakers, may be put resilient channels and more drywall to reduce noises from main floor.. also - add heating.. etc.Does someone have experience permitting someone's work? 

Walk through it & get a feel for the work needed, try your best to figure out if the heating needs to be replaced ($8,000), the roof needs to be replaced ($12,000 - $14,000), the electrical needs complete overhaul ($7,000 - $10,500), plumbing needs complete overhaul ($7,000 - $11,500).

I was wondering if any one had recommendations for plumbers, landscapers, cleaners, etc. our place needs a bit of work things such as changing out doors, adding plumbing vents and we’re having a hard time finding reliable people.

But we added new floors, paint and did some major updates to drywall, electrical and plumbing.

New everything - from plumbing, to electrical, to gutting all of the bathrooms and kitchen - it was done as if we would have moved in.

I have done and can do roofing, most plumbing, tile, carpet, hardwood, drywall, texturing, painting, gas lines (propane), electrical as far as switching out lights, switches etc. 

I prefer it because it makes it easy to do plumbing repairs and it’s easy to shore leveling issues.
