⚡ New Law — HB 4122 (Effective March 2026): Michigan's House Bill 4122 created a new streamlined process for junked and inoperable vehicles, reducing bureaucratic steps for removal in specific circumstances and updating notification requirements. Key changes are explained throughout this guide. If you are reading older Michigan guides elsewhere, verify the information is post-HB 4122.

What HB 4122 Changed — March 2026
Michigan House Bill 4122, signed into law in late 2025 and effective March 2026, updated Michigan's abandoned and junked vehicle statutes in several ways. The legislation was driven by complaints from property owners and municipalities about the backlog in the old notification process.
Key Changes Under HB 4122
- Streamlined junked vehicle removal: For vehicles that are clearly inoperable, visibly dismantled, or missing major components, the new law reduces the minimum notice period from 30 days to 15 days in cases where the vehicle presents a demonstrable safety or environmental hazard (leaking fluids, fire risk, structural instability).
- Electronic notification option: HB 4122 allows electronic certified notification (email or text with read receipt) as a legally equivalent substitute for physical certified mail in specific circumstances, reducing processing time for owner notification.
- Municipal lot authority expanded: Municipalities gained expanded authority to designate abandoned vehicle consolidation zones, reducing the burden on individual property owners in high-abandonment areas.
- Updated Secretary of State process: The SOS title claim form for abandoned vehicles was revised to align with the new notice periods and includes a new section specifically for HB 4122-qualifying junked vehicles.
- Scrap metal compliance: Junkyards and scrap dealers must now verify the vehicle history against a new Michigan SOS lookup before processing vehicles under 10 years old. This closes a loophole where stolen vehicles were occasionally processed as junk.
Note: HB 4122 created new categories and timelines but did not replace the general abandoned vehicle statute. Most situations still follow the standard process described below. HB 4122 primarily accelerates the process for clearly junked vehicles with demonstrable hazards — not every abandoned vehicle qualifies for the expedited track.
Michigan's Definition of Abandoned Vehicle
Under Michigan Compiled Laws § 257.252a (as updated by HB 4122), a vehicle is abandoned when it meets any of the following:
- Left on a public highway or street for more than 48 hours without being moved
- Left on public or private property without the owner's consent
- A junked, wrecked, or inoperable vehicle without a valid current registration
- Left at a vehicle storage facility for more than 5 days without the owner attempting reclaim
- Left on private property for more than 7 days when it poses a public safety or environmental hazard (HB 4122 track)
Michigan's 48-Hour Rule on Public Streets
Michigan enforces a 48-hour baseline for public streets — stricter than the 72-hour standard in most states. This applies statewide, but local municipalities may have additional rules.
Report to local police non-emergency
Call your local police department's non-emergency line or your city's 311 service. Provide the plate, VIN if visible, make, model, color, and exact location. In Detroit, report to Detroit Police at (313) 267-4600 or use the city's online reporting. In Grand Rapids, call (616) 456-3400.
Officer marks and tags vehicle
An officer marks the tires to establish the 48-hour baseline and attaches an official abandonment notice. The officer runs the plate through the Michigan SOS database to identify the registered owner.
Owner notification period
After tagging, the registered owner is notified through the address on file with Michigan SOS. The owner has a set period to respond and move the vehicle.
Tow to authorized facility
If the vehicle is not claimed, it is towed to a licensed vehicle storage facility. The owner has 30 days to reclaim the vehicle by paying towing and storage fees before the facility initiates a lien sale.

Removing a Vehicle from Private Property in Michigan
Michigan's private property process was updated under HB 4122, creating two tracks depending on the vehicle's condition.
Standard Track (30-Day Notice)
For a vehicle that is operable or whose hazard level is unclear, the standard process applies:
Document and report
Photograph the vehicle with date-stamped photos. Contact your local police department or Michigan SOS to initiate the notification process. File a written report stating the vehicle is on your property without consent.
Owner notification
After your report, law enforcement or the SOS process sends certified notice (now optionally electronic under HB 4122) to the registered owner. The 30-day response clock begins.
Wait 30 days
The owner has 30 days to respond and retrieve the vehicle. Do not proceed before this period ends.
Arrange licensed removal
After 30 days with no owner response, contact a Michigan-licensed towing or vehicle storage facility to arrange removal. Keep all documentation.
HB 4122 Expedited Track (15-Day Notice)
If the vehicle qualifies as a demonstrable safety or environmental hazard under HB 4122, you may use the expedited 15-day process:
- Vehicle must be clearly inoperable (missing major components) or leaking fluids onto your property
- You must document the specific hazard (photos of leaked fluids, missing wheels/engine, etc.)
- File the standard police report AND a specific HB 4122 hazard declaration form (available from your local police or Michigan SOS)
- The notice period under this track is 15 days rather than 30
- If the hazard is severe and immediate, contact your local code enforcement for possible emergency removal authority
Claiming Title to an Abandoned Vehicle in Michigan
Michigan's abandoned vehicle title process goes through the Secretary of State. HB 4122 updated the SOS form to include the new junked vehicle track.
File a police report
You need an official police report documenting the abandoned vehicle on your property. This is required for both the standard and HB 4122 tracks.
Request SOS owner lookup
Contact Michigan SOS to identify the registered owner and any lienholders. Use the Michigan SOS online portal at michigan.gov/sos or call (888) 767-6424.
Send certified notice
Under HB 4122, you may now use electronic certified notice (if you have the owner's contact information) in addition to physical certified mail. Keep proof of delivery either way.
Wait applicable notice period
Standard track: 30 days. HB 4122 junked vehicle track: 15 days (if vehicle qualifies). Do not file for title before this period ends.
File for abandoned vehicle title with SOS
Submit the updated abandoned vehicle title application to Michigan SOS with all supporting documentation: police report, owner notification proof, photos, and the completed SOS form. Use the Michigan SOS online portal or a branch office.
Inoperable Vehicle Storage in Michigan
Michigan does not have a single statewide outdoor storage rule — this is governed locally. Common Michigan patterns:
- Detroit: Inoperable vehicles must be stored inside an enclosed structure or fully screened from public view. Detroit code enforcement actively patrols for violations, particularly in neighborhoods with high vacancy rates.
- Grand Rapids: Inoperable or unregistered vehicles must be stored in an enclosed garage or behind a solid fence. Front yard and open driveway storage is prohibited.
- Ann Arbor: Strict — inoperable vehicles must be in an enclosed structure. Ann Arbor code enforcement responds quickly to complaints.
- Lansing: Similar to Ann Arbor — enclosed structure required for inoperable vehicles in residential zones.
- Michigan HB 4122 and storage: The new law does not change local storage ordinances. A vehicle undergoing active restoration may qualify for a temporary exemption in some jurisdictions — check with your local city.

Frequently Asked Questions — Michigan
HB 4122 applies if the vehicle on your property is clearly junked or inoperable (missing major components) AND poses a demonstrable safety or environmental hazard. If the vehicle runs, has current plates, or its status is ambiguous, the standard 30-day process applies. If you're unsure, contact your local police department — they can advise which track applies and provide the HB 4122 hazard declaration form if applicable.
HB 4122 defines qualifying hazards to include: vehicles actively leaking petroleum products or other fluids onto the ground, vehicles with structural instability that could collapse or fall, vehicles with exposed sharp metal posing injury risk, vehicles with pest infestations, and vehicles presenting fire risk due to condition. A vehicle that is simply unsightly, inoperable, or annoying does not qualify for the expedited 15-day track — a specific, documentable hazard is required.
Only if you have the owner's email address and can obtain a verifiable read receipt or electronic delivery confirmation. HB 4122 created the option for electronic certified notification, but it requires proof of delivery equivalent to what a certified mail green card provides. If you cannot obtain verifiable electronic delivery confirmation, use physical certified mail. When in doubt, do both — send electronic notice as a supplement, certified mail as the primary.
This is a common situation. Respond to the violation notice in writing immediately, stating that the vehicle belongs to someone else and was left on your property without your consent. Provide your police report number (file one if you haven't). Most Michigan municipalities will pause code enforcement action while you complete the legal removal process, provided you can show you are actively pursuing removal. Do not ignore the violation notice — failure to respond can result in fines even if the vehicle isn't yours.
