Property owners need to create an account on the city's web page.
City Assessor Brian Phelps says eight landlords have created accounts so far, but he knows it's going to be a slow process.
"The slow pace doesn't bother me a bit, because it's going to allow us to work any bugs out on the back end as we go through the approval process and getting people their certificates and everything. Hopefully things will smooth out a bit," he said.
Landlords have until June 30 to register their properties.
Those who don't will be taken to court and may have to pay legal fees.
