To truly confirm you would need to assess the chronology i.e. building was built in 1962, zoning changed/implemented in 1963, and it has continually been used as a 2 unit since that time therefor it is legal and non-conforming. 

Here is the language from the LA City ADU Implementation Memo from Feb 27, 2020:D.

in the end, make sure you have a killer acquisition machine and an implementation team around you. 

I understand RUBS in theory and have been asking my property management team to implement it but have been met with some resistance.

and only after you covered the "other" aspects of risk management (insurance, umbrella insurance, proper property management, etc.).Here is something to help assess the need for asset protection, and what to implement - my Asset Protection Decision Diagram : https://www.biggerpockets.com/files/user/CosIorg/file/asset-protection-decision-diagram Asset Protection Onion Diagram - what, when and at what cost one should implement in terms of asset protection - https://www.biggerpockets.com/files/user/CosIorg/file/asset-protection-onion-diagram-v2 What is needed for a complete asset protection OR the domains that need to be intersected to find asset protection

So any tax strategies should be implemented before the income is earned (entity structures, etc) or should be generated by other means (tax shelters, etc).Using either an S corp or a C Corp can allow you to reduce taxes in certain situations.

Every time you are in the unit check the smoke and carbon monoxide detectors.  

When you implement the program be sure to train your tenants on it.

For the cities that have implemented the amendments, this has resulted in changes where neighborhoods that were only zoned for single-family homes can now have fourplexes or townhomes built, and it is significantly reducing red tape around the parameters of where larger multi-family buildings can be developed.While the changes will provide ample opportunities for developers, existing residents in the neighborhoods may bear the burden of the ongoing construction and increasing population once the units are built and rented out.

Do you have a water, smoke or carbon monoxide alarm system?
