Denver hopes to require Landlords to obtain a license and register their rentals. They started doing this in 2019 with vacation homes and now want to do it for all rentals. Why? It's under the guise of protecting the public, but that's like requiring every adult to take a breathalyzer before getting into a car because 5% of the population may be drunk.

Notice there will be an administrative fee and an inspection every four years. That means more City employees to administer the program, shuffle the papers, inspect the properties, enforce the rules, collect the fines ($1,000 per day for a violation), etc. Taxes will go up.

Imagine a landlord with 100 rentals. Each rental would have to be registered and inspected once every four years. That will take a minimum of one hour of time per rental, adding 100 hours to that Landlord's workload every four years. Easy for a Landlord with 1-2 rentals but a larger Landlord or Property Manager will need to hire additional staff. 

Registration fees for the owner. The City will have to raise taxes to cover the administrative costs of the program. Large Landlords and Property Managers will have to hire more staff. This will all result in costs going up, which will be passed on to the end user.
