Usually found in a closet or a mechanical room.WaterIt is usually pretty easy to run water lines wherever they need to go.

A detached ADU (750 sq.ft) and a Junior ADU (200 sq.ft.)I'm about to finish the JADU so here is the breakdown,-$8k-$12k for Plans/Permits/Fees (I'm a Civil Engineer so I was able to save some money and time) The entire Plan Check Process with the City lasted almost 6 months.I did the construction as owner builder because I have construction experience and hiring a GC was out of the question because I'm not rich. 1) Rough (Plumbing, Mechanical, Framing and Electrical): Around $25k2) Finish: Another $25k\Time to build: 2 monthsNote: I was able to get quotes from different contractors and the cheapest I was able to get was $75k.

I would love to better understand the mechanics of how to *loan* yourself/your LLC money.
