Legal Question in Landlord & Tenant Law in California

Re: Property management/Renters Rights

Towed by whom? The government or a private company hired by the landlord or the landlord's property manager? Check your lease and tenant rules. You are, at a minimum, entitled to some kind of prior notice.

California Vehicle Code sections 22650 to 22711 probably apply; see, especially section 22658 (violations can expose your landlord to liability for double the cost of storage and towing).

California does not offer a grace period after your vehicle's registration expiration date. Instead there is a schedule of late fees that go from 10% to 20% (within 30 days after) and onward all the way up to 160%. However, a Planned Non-Operation may be filed up to 90 days after the registration expiration date if the vehicle was not operated in any manner, but appropriate late penalties are due.

Time is of the essence, so you should probably deal with this asap. Good luck.
