Deck Construction Permits in Baltimore
Local Rule
Baltimore City Department of Housing and Community Development
Baltimore City and Baltimore County are separate governments with separate permitting rules, and the city's own exempt-work list does not include decks at all, so any deck built inside the city line needs a permit regardless of size or height. This is stricter than Baltimore County, which does publish deck construction guidelines with pre-approved footing, ledger and guardrail standards. City permits are issued through the Department of Housing and Community Development's E-Permits system, distinct from the county's own online portal.

How This Compares to Maryland Statewide
Maryland has no county government, so there is no county-level rule to compare against. Here is what applies at the state level instead:
The only exception is a small freestanding platform 200 sq ft or smaller and no more than 30 inches above grade that is not attached to the house (IRC R105.2); any attached or elevated deck needs a permit.
