Tiny House

Casita II Tiny House | Post 014 | Electrical Rough-in

As someone who is routinely electrocuted…


I wasn’t very excited about having to wire an entire house from scratch. I did A LOT of research and so far as I can tell, if you can do basic math, you should be able to calculate all energy needs before drilling a single hole. Sounds easy enough, but we hadn’t decided on the majority of our light fixtures and I really needed some professional advice.

Luckily, a friend of our neighbor is an electrician AND happened to have loads of extra electrical supplies from past jobs.

Before we bothered creating a diagram, we walked around the tiny house and tried to imagine where we would expect to have light switches, outlets, and lights, then marked them accordingly. I consulted Shockingly Simple Electrical for Tiny Houses and used the diagram and key included in the book.

We chose all recessed LED lighting and what probably is too many power outlets. I recall reading multiple tiny house blogs where people wished they had more places to plug in, so we went a bit overboard.

Installing the ductless mini-split system was not difficult, but care has to be taken not to damage the copper piping. Since the outdoor condensing unit had to be mounted on the house, we chose to place it above the water heater. Since this is essentially the back of the house, it made sense to hide the services back there and it has the added benefit of the loft pop-out to shield it from rain. I built the brackets out of scrap metal, then painted and bolted them to wall studs on the pop-out.

The indoor unit is to be mounted above the front door, so I had to run the included lines from the condenser, through the walls and roof, and ending on the opposite side of the house. This task was not difficult, though laborious and time-consuming.


I also took this opportunity to wire in a single bluetooth speaker. Since the space is so small and generally open, one speaker should be sufficient for most areas of the house. We chose the Klipsch CDT-2650-C II in-stereo, ceiling mounted speaker and the Pyle Bluetooth receiver to connect to it. In testing, the speaker has great sound quality and Bluetooth range is roughly a 30 foot circumference around the house.


Lessons Learned

I completely forgot to account for a range hood fan above the stove, so I had to add another leg on the circuit that also powers the fridge. We are planning on a smaller, apartment sized fridge, so there should be no concern with overloading the circuit.
