Detroit: what the city records show

BriggsAnalytics reads seven independent City of Detroit record streams every day. This page reports what those records currently say about commercial fire and life-safety demand. Updated August 31, 2026.

A single record means a building needs a repair. Multiple independent records, arriving from different city systems at the same address in the same season, mean something structural is happening: a renovation, a change of tenant, a system at the end of its life, or an owner who has fallen out of their inspection cycle.

That distinction is the entire point of scoring. Of the 40 highest-scoring commercial buildings in our current Detroit pull, 16 are throwing four or more independent classes of signal at once, and three are throwing five.

Highest score in market 33

1000 Woodward Avenue

Detroit 48226

Signals stacked
Six inspections, two building permits, five trades permits, and three business licenses at one address. Four independent classes.
Named on the records
Multiple tenant fit-outs and a named fire alarm contractor already working the property.

A building generating this much permit and license traffic is mid-transformation. The work is already being bid. The question for a contractor is whether they are on the list.

Most signal classes 31

FIRE DEPARTMENT LOG: ALARM MALFUNCTIONING

Somebody worked on this system and it is still failing. That is a service-takeover conversation, not a cold call.

Every figure on this page is checkable.

These numbers come from the City of Detroit's own published records, read daily and grouped by property. We publish aggregates and redacted examples here. Subscribers receive the full addresses, the owner of record, and the official record ID for every signal, so nothing has to be taken on faith.
