Start by separating the dated project events on a Baltimore building permit master card. The Maryland State Archives’ BRG48-53 finding aid describes an address-based index in which one card can summarize several applications and permits. Treat each numbered entry as its own event and request the underlying permit rather than using the card as one approval.
The catalog describes cards from 1924–1961. That is the series range; individual addresses, years, cards, permits and underlying files may be missing. These are Baltimore City records. A Baltimore County property belongs with a different custodian; the city-versus-county guide helps preserve that boundary.
Find the card by block and address identity
The Baltimore City Archives’ property-record guidance says the Building Permits Index Cards are arranged by block. It points readers without a block number to the State property page, where the account identifier supplies it.
Before requesting a card, assemble:
- Current address and any documented historic street-number or street-name variant.
- City block number, if already confirmed.
- Approximate construction or alteration years.
- Owner, contractor, structure, or use clues already present in another record.
- The series citation BRG48-53 and a reel or item citation if the catalog supplies one.
The finding aid lists numbered block ranges under film reels and item citations. A block match narrows the archive locator; ask the Archives whether the card is digitized and whether the listed permit files remain available.
Turn one card into an event ledger
The series description lists address and owner identity, division or section, block and lot, application date and purpose, permit number and date, construction cost, completion date, and remarks. Read those fields by event.
Create one row in your notes for each distinct project:
- Application date and stated purpose.
- Permit number and permit date.
- Work description or use affected.
- Completion date only when the card associates one with that event.
- Remarks and any cross-reference.
- Underlying permit, inspection, plan, or occupancy record still needed.
An application date marks the application, and a permit date marks issuance; a passed final inspection is a later event. A completion-date field is a useful clue, while the inspection report or Certificate of Occupancy is a separate record. Use the final-inspection status guide when the terminal project status matters.
Reconcile a fictional multi-project card
Imagine a fictional card showing a 1948 porch application and a 1956 interior alteration under different permit numbers. A completion date appears beside the porch entry, while the later alteration has only a permit date and a remark.
Record these as two projects. Request the 1948 underlying permit if the porch scope matters. For the 1956 work, request the permit and its inspection or closeout evidence rather than carrying the porch completion date forward. Each project keeps its own outcome, even on a shared address and card.
If the same property also has a zoning appeal, keep that case separate. The published Baltimore zoning-appeal index guide covers BRG53-3 address cards and appeal files. A zoning decision can explain a land-use action without proving that the related construction permit was issued or finalized.
Ask the Archives for the precise missing object
The Baltimore City Archives current notice said on October 5, 2026 that the research room was temporarily closed for renovations, with reopening planned for October 14. Archivists continued remote assistance by phone and email. The page also says visits are by appointment and require staff confirmation. Recheck that notice before planning a visit.
A focused inquiry can include:
- BRG48-53 and the relevant block range, reel, or item citation.
- Address and documented historic variant.
- Approximate date and the particular card entry sought.
- Every permit number and date already transcribed.
- Exact missing object: card image, underlying permit, inspection entry, plan reference, or another named record.
- A request for staff to explain which citation to use when the catalog range or card cannot be matched.
A missing catalog image or unsuccessful card search doesn’t prove that no permit existed. Preserve the failed key and ask the custodian what record or series should be checked next.
A master card shows construction history. Whether a space was approved for its use is a separate question, covered in how Baltimore BUSE records differ from final construction permits.
