In the face of a transforming housing landscape and tightening availability, California has embraced Accessory Dwelling Units (ADUs) as a beacon of opportunity and practicality.

Constructing an ADU (Accessory Dwelling Unit) to enhance cash flow and equity.Partners:- Parents: They've contributed 50% of the cash needed.

I have been looking at the Nashville market to buy 5+ acres, owner occupy the main dwelling and build tiny homes or other accessory dwellings on the property for short term rentals.From what I gather, AR2a zoning (which nearly all these sorts of properties are) disallow accessory dwellings, but somehow allow mobile homes, accessory apartments, and two-family dwellings.

I currently have one permitted detached accessory structure and detached garage on my property.

While your looking you can also see if you can get a single family with a big enough lot to add an ADU (accessory dwelling unit) to add value as well to your property.

Zoning in the Bay Area does not allow for this (1 primary + 1 accessory max, if that) — so I’m wondering if you know any markets across the country that do?

It looks like lathe and plaster which means the walls are most likely a thick mud wall with plaster embedded with wire which is a bear to remove, hopefully that quote is for a full gut and replace, but I would just update the floor, have the wall tile painted, tub glazed, new shower fixture, vanity and accessories like towel bar, shower curtain. 

It has an accessory apt permit.

I spent some time talking to the City of Anaheim planning dept this week and its still no one can give you a straight answer, we were looking to do a junior adu and they do not allow anything  less than 400 sq feet. https://www.anaheim.net/DocumentCenter/View/21828/Accessory-Dwelling-UnitsFullerton just passed some new legislation that encourages the ADu Anaheim has more resistance.http://www.nocchamber.com/news/details/city-of-fullerton-reduces-fees-for-adus

SB 13 bans impact fees for units smaller than 750 SF, but for units larger than that it has this text:"Any impact fees charged for an accessory dwelling unit of 750 square feet or more shall be charged proportionately in relation to the square footage of the primary dwelling unit."
