Can Landlords Raise Rent on Outdated Dump to Same as Updated?

[Account Closed]

We rent, we live in a nice condo complex from the 70's.  Most units have been nicely updated, new weather efficient windows, doors, carpet, paint, updated bathrooms and kitchen, etc.  Not ours... our unit has never been updated since the 70's, and is crumbly.  However...we don't complain ever because our rent is $600 lower than all of our neighbor's with updated units, and we'd rather have lower rent than updates.  BUT NOW our landlord is starting to raise the rent due to the area comps, but can she do that when ours is a dump compared to the others?  We're in California.

And, if she raises our rent (slowly) to $600 more (over time, per law requirements), can we require her to update our windows to energy efficient windows and doors?  (Our heating bills are over $400/month in the winter due to heat loss.)  New carpets, updated bathroom and kitchen appliances, etc.?

Thanks.
