Less than two years after the passage of legislation creating significant new protections for tenants in Colorado, the state Senate on Tuesday gave first-round approval to a bill expanding renters’ rights, The Denver Post reports.

The measure does not make many changes to current law, but Republicans, who opposed the bill, said they were major and would hurt landlords and renters.

“The result of this, truly, in my opinion, is probably going to be higher rent,” said Sen. Scott Renfroe, R-Greeley.
