After reading como-estas' CO Springs Independent story above--that's also a silly one.  Any landlord worth his salt will also have a tightly worded clause requiring ALL tenants' names (including children and pets) to be specified on the lease contract.  That way, If someone has a "buddy", or a "boyfriend" move in later without the landlord's written approval, it becomes a violation of the Lease contract--and subject to another "additional tenants" surcharge, followed by written demand for retro-active charges due, then eviction for non-payment, if necessary.   

...sorry to keep responding como, I just don't want this shoddy DP journalism putting false ideas in Denver dead-beat renters' heads, then making more unnecessary trouble for the rental and homelessness industries.  Yes, evictions are expensive for landlords, but far worse for a renter or homeless person with a court-ordered eviction on their record. Most landlords won't even give an evicted applicant a call back.
