I grew up in OC but I also really like San Diego and the Pacific Northwest.I ran across this site while doing some internet research about accessory dwelling units, and it occurred to me that since I have no pressing need to move back into my LB house I am essentially already a real estate investor, so I figured I might as well sign up and learn something about real estate. 

Accessory dwelling units have also become an increasingly popular value-add strategy for many of my clients.

You can not split it into a multi, but you may be able to add an accessory dwelling unit. 

., as an accessory dwelling unit. 

Hi all,I have a small ranch in an area that prohibits any sort of accessory dwelling rental / mother in law apartments / short term or long term rentals.

However it doesnt mean they didnt exist at all because creative people who've added units, ADU's - accessory dwelling units, and or redeveloped property were able to push rents dramatically from where they were back in 2008 till present 2021.As of right now if you were to go on the MLS to look around Id bet its around .4% to .5% of asking price atleast in areas we're buying in. 

Per code the max sqft for accessory structure is 750sqft.

Accessory dwelling units (“ADUs”), which are essentially another small home added on an existing lot, are increasingly being built as a response to housing shortages.

If the second unit does not have its own electric meter it should still work (worked for us,  we bought a home with attached apartment with our daughter who was a college student) also if the appraiser classifies the second unit as an accessory apartment or mother in law unit or casita instead of calling it a "duplex"   We're taking a gamble on a property right now where the underwriter said he believes the appraiser will be classify it as a single family with accessory unit (fingers crossed) this property is two separate homes with separate meters, so there's a chance appraiser will say the dreaded "duplex" and we wont qualify. 

The other accessories I paid retail at the local HD.
