Do I need additional a zoning permit in Baltimore?

[Sarah 'Sadika' J.]

I’m purchasing a row house in Baltimore City. Currently, it’s listed zoned R-6: “Low density rowhouse neighborhoods. Landscaped front yards, setback buildings.Accommodates detached and semi-detached dwellings, rowhouse developments and multi- family developments. Limited non-residential uses.”

I want to convert the basement unit as a separate unit, with proper bed, bath, kitchen, and separate meter.

Do I need get a zoning permit to build another unit? I know I’ll permit for bathroom, bedroom, kitchen etc but I wanted to make sure about zoning permit.

Thank you
