Check with the Condo Association (if any) for their possible needed approvals & outside requirements...noise levels & when you're even allowed to make noise, windows, doors, shutters, porches, siding, roof, etc. They usually just care about the outside aesthetics. But, they could kill the whole plan with a simple little guideline like, only professional licensed & bonded contractors...so you don't burn everyone down.
But absolutely, consult with a Plumber, Electrician, Carpenter, General Contractor or Design Builder if it's a "Remodel" where you plan on moving or removing walls & their utilities or even just utilities. Opening walls means being required to update the utilities to today's standards.
If it's a "Renovation" where you're not opening any walls floors or ceilings all the way to the structure & just re-painting & replacing tiles, cabinets, appliances & fixtures to not move a single utility, then have at it.
Otherwise, do you just want a dumpster at the start for demolition or removing the old stuff & then another dumpster at the end for all the new stuff's scraps & errors. Or, will you just call 1-800GunkJunk (for example) when the pile fills the room.
Do you have any experience in anything you're doing or do you have any problem with following manufacturer's instructions to the letter. If you're just going to wing-it, then be prepared to rip out what you did wrong & re-buy everything to start over.
This isn't a few weekends here & there situation for either the Remodel or Renovation scenario. You need a lot of tools, strength, stamina, positive attitude & the ability to live in filth for a year.
