Lawrence city commissioners want more information about a possible fee increase after a city audit determined the city’s rental registration program is not paying for itself.

Commissioners also said they wanted a staff report on various scenarios that would allow the rental registration program to be expanded to cover more type of rental units.

Currently, the program only requires rental homes in single-family-zoned neighborhoods to be registered with the city. The program charges a $25 annual fee, and properties are inspected once every three years.

But City Auditor Michael Eglinski said the fee likely would have to be raised to more than $40 for the program to come close to covering its costs. He also said the program only covers about 10 percent of all the rental units in the city.

Commissioners made no decisions Tuesday but did ask staff to prepare a report for further discussion in the next several weeks.
