If you're planning on building an ADU or JADU 'yourself', my suggestion is to make sure you have some previous knowledge of construction and also make sure you know good sub-contractors in the following trades:  electrical, plumbing, foundation, roofing, framing, drywall/paint, stucco, tile, cabinetry, flooring, HVAC, concrete, etc.The last thing you want is poor quality work that has to be re-done because a handyman or the wrong tradesman did the work.

New refrigerator, dishwasher, granite counter top and sink, new faucets and plumbing, fully furnished.

Raised foundations tend to be easier to add bathrooms because plumbing can be moved under the house such as from an existing laundry room.

We are only missing a plumbing license, which I plan to hire part-time soon.

bathroom rehab depends on plumbing but i expect min. 3K for lighter one.kitchen rehab is about 2-3k ; the cabinet is not expensive.that's labour and materials. 

Featuring brand new roof, new windows, completely new electrical system, completely new HVAC system, brand new plumbing inside the house, and all new designer cosmetic updates, luxury inter-locking vinyl floors & luxury stretch ceilings with recessed lighting & full landscaping with new sod up front.
