How many code violation leads does Detroit generate?

PermitGrab tracks 5,815 Detroit code-enforcement cases filed in the last 90 days across 2,313 distinct property addresses, current through late June 2026. The largest channels are certificate-of-compliance cases (1,253 combined), unlawful-parking cases (686), rental-registration failures (591), inoperable vehicles (541), bulk-waste accumulation (428), and vacant-building registration (362).

Why are Detroit code cases good for real estate investors?

Detroit publishes a deep stream of vacant-building registration cases (362 in 90 days) and rental-registration failures (591) — both strong tells for non-owner-occupied, deferred-maintenance properties. Investors and wholesalers use them to find distressed properties before they reach the market.

Which contractors benefit most from Detroit code data?

Real estate investors and property managers for the vacant-building and rental-registration cases; general-repair and exterior contractors for the certificate-of-compliance caseload; and lot-clearing, junk-removal, and towing operators for the weeds, bulk-waste, and inoperable-vehicle cases.

A code violation is a deadline. When Detroit cites a property, the owner is on a clock to correct the problem before the case escalates and the fines compound. For a contractor or an investor, that is a fundamentally different lead than a permit: the work is already required, the owner is already on the hook, and most of the time nobody else is calling.

Detroit publishes a deep, current enforcement caseload, and PermitGrab tracks it: 5,815 code-enforcement cases filed in the last 90 days across 2,313 distinct property addresses, current through late June 2026. The value is in knowing which slice maps to billable work, and the Detroit feed breaks down into a handful of channels that each point somewhere useful.

The Caseload, Broken Down

Certificate-of-compliance cases — 1,253 combined. Owners cited for failing to obtain a certificate of compliance on residential and commercial buildings — a property-condition channel for general-repair, exterior, and code-correction contractors.
Rental-registration failures — 591 cases. By definition non-owner-occupied rentals whose owners have deferred a compliance step — a strong tell for investors, property managers, and the repair trades that service rental portfolios.
Inoperable motor vehicles — 541 cases. Direct work for towing and junk-vehicle-removal operators.
Bulk solid-waste accumulation — 428 cases. The cleanout-and-haul-away channel.
Vacant-building registration — 362 cases. One of the strongest distressed-property tells, for investors and rehab contractors.
Excessive weeds and plant growth — 333 cases. The lot-clearing and landscaping channel.
Unlawful parking on lawns and unpaved areas — 686 cases. Surfaces problem properties worth watching.

Every case carries a property address and a filing date, so you can sort the freshest vacant-building or rental-registration cases, map them to a neighborhood, and reach the owner while the deadline is live.

Why a Violation Beats a Permit on Close Rate

A permit lead is competitive — every contractor watching Detroit sees it the moment it is filed. A violation lead is the opposite. The owner did not plan the work; the city found the problem and set a deadline. They want the case closed before re-inspection, and almost nobody works this channel while everyone chases permits.

Detroit Has a Live Permit Side Too

The violation feed sits next to a working permit stream. PermitGrab tracks 2,917 Detroit building permits filed in the last 90 days, current through June 19, 2026. For trade contractors who want planned-project leads instead of distressed-property leads, that permit stream is the other half of the same daily feed.

Who Should Be Working Detroit Code Cases

Real estate investors and wholesalers can research vacant-building and rental-registration cases as published property records. Property managers can review rental-registration flags alongside the published address, case type, and filing date. General-repair and exterior contractors can review the certificate-of-compliance caseload. Lot-clearing, junk-removal, and towing operators can review weeds, bulk-waste, and inoperable-vehicle cases. A case record is not a request for service or permission to contact a property owner.
