Curious what is legally allowed - could you charge a flat fee for usage up to a certain amount then charge extra for above that? 

According to this post it seems like they have limited their API usage a lot. https://github.com/hanneshapke/pyzillow/issues/22Was in the process of doing something simple where I:1.

I have a home in DC that may be vacant pretty soon and was interested in finding out how to submit my home for embassy housing pool usage. 

I know my father in Florida has seen a dramatic rise in his premiums, and with my own clientele on at least three occasions we needed to shop extensively for insurance coverage that was not only reasonable but also provided the coverage the property and usage required. 

CA is lenient in how utilities are partitioned as long as disclosed, but must be based on property usage.  

For example a list to check out the usage of water, pass heating bills est.

Demand that any future PM add it to their lease, unless they can cite you chapter and verse of the state statutes where your properties are that forbid it.  .Wear and Tear: TENANT AGREES THAT DIRT, FILTH, GREASE, GRIME, SMUDGES, DINGS, HOLES, STAINS, SCRATCHES, TEARS, CRACKS, CHIPS, AND BREAKAGE does not constitute normal usage and will be billed as damages. _____ _____ _____ _____ (initials)

Or alternatively, I could say to my second floor tenants that I need to expand the lease to cover the third floor, but offer to find a sub-lessee who would take on the third floor space and operate completely independently from them, and split utilities according to usage?

This approach encourages them to be mindful of their consumption and find ways to reduce utility usage, ultimately leading to lower bills.

The energy usage would be minimal unless the laundry room is a laundrymat in disguise.
