Lay out sewer, water, electric lines

I don't know if it's counter intuitive or not but your best intermediaries are going to be in the cluster of the middle range of fees.  

Not at all.... the rent is based on the market rate, so if the units are all different...size/location/lay out/age etc etc... they would have different markets rates.

I don't know your market but it looks like a lot of thought went into the design and layout. 

Finding a property with the appropriate layout is challenging and expensive.

It seems counter intuitive to call for that level of development, and then turn around and throw landlords under the bus during the Covid crisis.

The layouts are easier to work with and manipulate to make the space feel as modern as possible. 

Advice on Layout/Design: For those who have added ADUs, do you recommend standalone units, garage conversions, or a combination of both?

Great stuff - this type of regulation is somewhat counter-intuitively a lot better for investors than currently less regulated markets (where you don't know what could change dramatically in the future). 

Quote from @Mary Jo Carruthers: I have seen houses where folks did it anyways without the permit but that is really value destroying as it will make it very unlikely to sell for top dollar with that layout.
