Another debate over large boarding houses and the amount of on-street parking they consume in the Oread neighborhood is set for Lawrence City Hall. City commissioners at their meeting today will review new information compiled by staff members that shows a recently approved change in the city’s code could allow about 20 percent of all homes in Oread to be converted into boarding houses.

The code change created an “exception” that generally allows houses of more than 3,500 square feet to qualify for a lesser parking standard when converting into a boarding house.

City staff members are estimating that 83 homes in Oread could be converted into boarding houses under the new code. The high number is in part because the code requires the city to count basement square footage when determining if a home exceeds the 3,500-square-foot threshold.

If basements were removed from the equation, the number of homes eligible to convert to boarding houses would drop to 10.

Commissioners meet at 6:35 p.m. today at City Hall.
