From Northern California to LA, inland temperatures are expected to exceed triple digits in many areas for July 4th weekend.For those that have ever tried to sleep in 80+ degree weather without AC, you will recall...it isn't fun?

Whichever one makes you sleep better at night, choose that one. 

if you can somehow - you rent out all the rooms in a house and sleep on the couch or in the garage or something - that's fantastic. 

He'll be working on 5 hours a sleep of night (if he's lucky) and you likely less.

Realistically a cheap ac repair is $250, you’re losing time/money/sleep over an additional $250.

This does very well with no complaints and I stay pretty full.The other place has King Suites( one bunk bed room) and already sleeps 23 so I've left this configuration alone for now.

The window must have a net clear openable area of 5.7 square feet (5.0 square feet if ground floor), a minimum openable height of 24 inches, a minimum openable width of 20 inches, and the bottom of the opening must be within 44 inches of the floor.Size: The room must be at least 70 square feet, and no less than 7 feet in any horizontal dimension.Lighting & Ventilation: A natural light source (window) of not less than 8% of the floor area and natural ventilation (openable window/door) of at least 4% of the floor area are required.Heating: The bedroom must have heating capable of maintaining a minimum room temperature of 68°F.Smoke Detector: A smoke detector is required in each sleeping room.While a closet is expected in most bedrooms, the International Residential Code does not actually require a bedroom to have a closet.

It is my understanding that you cannot use the ADU for short term rentals in Los Angeles.https://therealdeal.com/la/2019/10/29/while-you-were-sleeping-la-bans-granny-flats-as-airbnbs/If you make the ADU all electric (like I did on mine), then you don't need to worry about splitting the gas. 

Other than that I dont give an F who you sleep with

In the short term it can be overwhelming, you lose sleep, you worry about other hidden issues popping up, you second guess your decision to buy the property (buyer's remorse).So, what happen to the two property I listed above?
