I'm looking at the potential of building a home where the water suppliers pressure is near minimum…in the 35-40 psi range. If you are doing it on the front end, how expensive is it to add a pressure tank and booster pump to the homes plumbing?
How big of a problem to maintain? And how bad does 35 psi feel (35 psi at meter would be about 32 at shower head).?
Doesn't sound like you have much choice at this point unless you're okay with bad water pressure.
In the grand scale of cost to build a house, it's a drop in the bucket. Assuming the topography comes into play because you're in the mountains (cold winters) make sure you understand freeze protection for the tank and plumbing as well. Adding some low voltage heat cables and heat mats from the source throughout the plumbing system, below and around the tank, and along your pipes during construction is fairly inexpensive and great piece of mind.
Another alternative or backup is to add a large cistern for rain / snow runoff catchment to at least be able to use for utilities in case the city system fails.
