Through state law that only applies to Montgomery County, apartment buildings already must provide a public place for election and campaign materials to be shared with residents (pg. 22 of state election law here). Minnesota law goes further and makes it unlawful for candidates to be denied access to an apartment building, dorm, or nursing home. Also, this goes beyond my expertise but here is a link to at least one piece of case law on access to apartment buildings in DC which found that it could not be limited. In Takoma Park, the changes we are discussing would more meaningfully allow access to candidates. We are also discussing ways that perhaps individual residents could opt out.
An additional part of this effort is to have a city-provided welcome packet that could be mailed to new residents or given to landlords with the requirement that they distribute to new renters. Such a packet could include a great deal of information which should include voter registration forms and information about city elections and city government.
