It's on the outside of the footing for easier installation, because the ground on that side is more moist, and because moisture does travel through concrete and into the crawlspace. 

As this is my first first foray into the Tacoma market and given the pandemic, I am just looking for more concrete information regarding the state of STRs.

We've worked with the same GCs, roofing, concrete, painting, stucco, granite, electrical and HVAC contractors so when we call them, we get a response because a) they know we already have the work lined up and b) we pay fast.

You pass on enough maintenance costs like this to your tenants in the interest of saving your time and money, you'll be posting about how your mean and cruel tenants unloaded fifty pounds of concrete down your stack just before they disappeared in the middle of the night and you're now stuck with a 10 grand bill to run a new line in, how could they possibly be so cruel and mean to you?

Using the example of being a civil engineer, I can take a class on how to design a bridge using steel and concrete - and I know about how its done, but that does not mean I could do it and be successful at it. 

@Wane Tango , yea I had a similar experience where I was sending post cards for a concrete business I was running.

There is a large concrete side yard that has plenty of space for two cars, so the garage could be converted.   

In Oceanside ( San Diego) I just paid $7k for plans and engineering for a two-story ADU / JADU design, I have another 4k in Survey work and concrete certificates and about the same in soil testing since it's a two-story.

Both can be helpful.Either way, appointments are typically time-limited, so you won't necessarily have the ability to dive deeply into everything, and depending on who you speak to, you may not get concrete/confident answers.

@Mark Baldwin I just bought a house flip with a bad foundation and my concrete contractor said you can either cut out the bad parts and replace them or replace the whole foundation.
