I am considering doing this, unfortunately my builder only placed one faucet on each side of the house and I would need to install one closest to my garden plot. Does anyone have any idea how costly this would be? It would be near a bathroom if that matters!

Thanks in advance—GG

Cheapest way is to buy a “Y” from your local hardware story and run a secondary hose to the garden ($10 tops).
And you can add a battery operated timer to that line if you want ($ 20 and up).
Or you can do it more permanently by splitting the line before the faucet; most folks are not inclined to tackle that, but would be $$$ calling a plumber I am sure (materials under $50).
YMMV

I spent about $20 for materials to add a hose faucet to the side of my house closest to the garden. I did the work myself, and have all the tools, etc. handy. It’s not hard at all if you have a little experience sweating copper pipe together.

It shouldn't be that expensive for a plumber to tap into your coldwater supply and run PEX to a hose bib. While I prefer copper piping, PEX is quite common in newer construction, and running a new line for a hose bib is really quite easy. It shouldn't take him long. Call a plumber and get an estimate, and if there's other places you'd want a bib, might as well do it all at once.
