Search Grand River-St MarysFigures cover the Grand River-St Marys neighborhood (the boundary outlined on the map), over the last 12 months, compared against the average Detroit neighborhood. Source: City of Detroit open data. Detroit’s permit data lists building permits that have been issued (2019 onward), with no status or expiration date: permits count as active for a year after issue (longer for large projects), and revisions to an existing permit are left out. Open data updates on a delay, so the most recent records may be incomplete. For general information only — not legal, financial, or real-estate advice.
