(A) For an accessory dwelling unit described in subparagraph (A) of paragraph (1) of subdivision (e), a local agency, special district, or water corporation shall not require the applicant to install a new or separate utility connection directly between the accessory dwelling unit and the utility or impose a related connection fee or capacity charge, unless the accessory dwelling unit was constructed with a new single-family dwelling. home."

And California also capped security deposit, thus literally robbing landlords by AB 468 that's faking human right issue.If there is class lawsuit, I want to be the first to jump on.But my question is, why landlords are so docile to this evil law?

Currently, we have boilers and radiators that we want to remove to create space in the basement for a future conversion into another dwelling unit.

I’m having a difficult time trying to figure out the rent value of my 5 bedroom, 3350sf single-family dwelling in Oceanside California.

It's human nature.So you have someone running an illegal business on your business premises.

@Jason Merchey For more details, check out title 37, chapter 22 of the SC State law: http://www.scstatehouse.gov/code/t37c022.php (emphasis added):(30) "Mortgage loan" means a loan made to a natural person primarily for personal, family, or household use, primarily secured by a mortgage, deed of trust, or other security interest on residential real property or security interest arising under an installment sales contract or equivalent security interest against the borrower's dwelling and: (i) located in South Carolina, (ii) negotiated, offered, or otherwise transacted within this State, in whole or in part, or (iii) made or extended within this State.By definition, you didn't "make a mortgage loan" in the context of the legislation.
