Possibly already permitted outbuildings that already have plumbing such as workshops, offices, etc might be able to be converted to an ADU at a cost that does not result in the cost being more than the value added.Building an ADU is a lot of work and can be a slow process.

Then it's simple, build the home, find crews to do the work (you should already have them basically from the prior step), excavation, concrete, sealing, framing, roof/gutters/siding, windows, insulation drywall, plumbing, HVAC, electrical, finishes, etc. basically in that order.

Will need about 10k of cosmetic work and some minor plumbing.
