On February 3, 2020, the Michigan Department of Health and Human Services (MDHHS) activated its Community Health Emergency Coordination Center to support local and state response to the coronavirus. On February 28, the State Emergency Operations Center was activated by Governor Gretchen Whitmer to assist with coordination. On March 3, the Governor created four COVID-19 Task Forces: State Operations, Health and Human Services, Education, and Economy/Workforce. A state of emergency at the state level was declared by the Governor on March 10. It was renewed several times, the latest expiration date being October 27, 2020.

On March 13, The Michigan Department of Corrections banned visitors to prisons, along with prohibiting any volunteers from the prison. Staff at prisons would be required to have their temperature tested and be proven to be under 100.4 °F, along with other measures.

Michigan Secretary of State Jocelyn Benson issued an order starting March 16 to limit all Michigan Secretary of State branch offices to appointment-only instead of walk-ins. The only services provided by the offices would be for those applying for new licenses and IDs, for title transfers, and for testing for a license. All branches werel no longer open on Saturdays, with most weekday hours expanding. For those renewing their licenses, the proof of car insurance requirement was waived, along with late fees associated with the change.

On March 13, Whitmer banned all gatherings of 250 or more people in a single space, with limited exceptions. The ban was lowered to 50 people on March 16 per a CDC recommendation, and bars, restaurants, entertainment venues, and other businesses to partially close for two weeks.

On March 20, Whitmer signed an executive order banning landlords from filing eviction requests against tenants until April 17, which she said "relieves courts from certain statutory restrictions to enable them to stay eviction-related proceedings until after the COVID-19 emergency has passed". On April 15, Whitmer ordered nursing homes to transfer coronavirus patients to separate units or special facilities and banned evictions from nursing homes. The order was in effect until May 13. On June 11, Whitmer extended the freeze on residential evictions for non-payment of rent to June 30.

On March 24, a statewide stay-at-home order was issued, limiting all non-essential travel and discontinuing all non-essential business services and operations. It was originally set to expire on April 13, but was extended until April 30 with several new social distancing restrictions. Failure to abide by the order was punishable with a $1,000 fine or 90 days in jail. The order was later extended to May 15, with some restrictions lifted and others added, such as mandatory face-covering usage in public buildings and businesses. The order was later extended again until May 28 and added modifications of the restrictions from previous orders. In June, Whitmer extended the face mask requirement until July 15. On July 10, she extended the requirement and added a provision in which businesses can be fined $500 for not enforcing it and customers may be refused service for failing to wear one.

Several of the restrictions on businesses and medical facilities were lifted in late May. On June 1, Whitmer announced that the stay-at-home order was partially lifted and that Michigan was in stage four of its six-stage re-opening plan. Outdoor crowds of up to 100 people were allowed starting June 1. Restaurants and bars began re-opening for indoor dining services starting June 8, and other restrictions on businesses were loosened. Hair salons, barbershops, and similar businesses were allowed to reopen on June 15. Starting July 31, indoor gatherings were limited to 10 people and bars would be closed for indoor service and outdoor gatherings to 100. On August 14, Governor Whitmer announced four million masks would be distributed to vulnerable populations in Michigan. Movie theaters and other entertainment venues were allowed to re-open on October 9.

On October 29, the MDHHS issued a new mask mandate and crowd size limitations for public places, businesses, private gatherings, and restaurants.

On November 15, after several days of record highs in new cases, Governor Whitmer announced the MDHHS had ordered the closure of several businesses and services for three weeks, effective November 18. High schools and universities were closed to in-person learning, and organized sports (except for professional) are on hiatus. Businesses ordered to close included live theaters, movie theaters, stadiums, arenas, bowling centers, ice skating rinks, indoor water parks, bingo halls, casinos, arcades, and group fitness classes.

On December 18, the state announced an extension of the shutdown for indoor dining and bars for four weeks, but allowed other indoor entertainment venues like theaters, casinos, bowling alleys and indoor gun ranges to reopen with capacity limits, and a ban on concessions. All schools were allowed to reopen on January 4.

2021
On February 8, 2021, the Federal Emergency Management Agency gave Michigan DHHS $8,375,955 for COVID-19 vaccination distribution efforts.

Facing a COVID-19 surge in April, Whitmer hoped to avoid more mandatory shutdowns and asked Michigan residents on April 9 to take more "personal responsibility." She asked White House to send more vaccine doses. which was denied, in large part because the protection provided by vaccines activates only after several weeks, while the need to prevent new infections was immediate. On April 12, CDC Director Dr. Rochelle Walensky argued that asking for voluntary quarantine would not be enough. She said that Michigan needed "to really close things down, to go back to our basics, to go back to where we were last spring, last summer, and to shut things down."

In May 2021, it was determined that Governor Whitmer did not follow Michigan Department of Health and Human Services (MDHHS) self-quarantine rules upon her March trip to Florida.

Education
As of March 11, 2020, all campuses of the Lake Superior State University, University of Michigan, Western Michigan University, Wayne State University, Michigan Technological University, Northern Michigan University, Michigan State University, Grand Valley State University, Saginaw Valley State University, Central Michigan University, and all community colleges, had various restrictions on students and faculty in response to the virus.

Executive Order 2020-05 included the closure of all K–12 school buildings from March 16 through April 5. On April 2, the order was updated to suspend the remainder of the 2019–20 school year unless crisis restrictions are otherwise lifted. The order included guidelines for the development and distribution of home learning materials. Additionally, all high school seniors would be given the opportunity to graduate on their previously anticipated date.

On March 13, the Michigan Department of Education was granted a federal waiver by the United States Department of Agriculture. The waiver allowed for students who receive food from the Unanticipated School Closure SFSP to not be mandated to receive the food in a group setting. The Michigan Career and Technical Institute suspended all programs until April 5.

On June 30, Governor Whitmer released the state's "Return to School Roadmap" containing three proposed plans for re-opening K-12 schools for the upcoming 2020–21 school year.

On August 18, Michigan State University moved all classes for the fall 2020 semester to virtual learning.

In December 2020, two veterinary students appeared before the MSU Board of Trustees, on behalf of the graduating classes of 2023 and 2024, to request a tuition rebate for months of online instruction after originally expecting a mix of in-person and online courses. MSU President Samuel L. Stanley Jr. commented that a refund wouldn't be practical due to the university's fixed costs. In January 2021, MSU instituted a lockdown for the minority of students who had returned to campus, asking all in-person students to primarily stay in their residences for two weeks, citing a rapid increase in the university's COVID-19 positivity rate.

In early February 2021, senior nursing students in the Baker College system began to directly administer vaccines to patients at sites throughout Michigan, under the supervision of nursing faculty.

The University of Michigan (Ann Arbor campus) required students to prove they've been fully vaccinated by July 15 to live in dorms in fall 2021 and subsequent semesters. Michigan State University subsequently decided to require COVID-19 vaccination and masking for all new and returning students by August 31, citing new CDC data regarding the contagiousness of the Delta variant.

2020
On March 10, Attorney General Dana Nessel set up a hotline to report businesses price gouging goods such as toilet paper, meat, milk, bread, bottled water, face masks, hand sanitizers, and cleaning supplies. Sellers faced fines if their asking price was at least 20% higher than it was on March 9, after an executive order from Governor Whitmer banned the practice, until April 16. On March 19, Nessel sent a cease and desist letter to Menards after her investigators found evidence of price hikes, sometimes doubling the retail cost, on high-demand bleach and 3M face masks. In other instances, tipsters reported seeing face masks that cost $10 each, cases of water for $35, and bottles of hand sanitizer for $60. Whitmer issued a second order on March 20 which "focuses enforcement resources on the cases most pertinent to the emergency by clarifying which price increases constitute price gouging." As of April 14, 3,541 complaints had been received.

On March 20, Whitmer signed an executive order for medical and dental facilities to postpone any "non-essential" procedures, such as plastic surgery and teeth whitening, beginning March 20 through the time the State of Emergency is lifted.

A total of $622 million of federal money for rental assistance became available to eligible Michigan residents starting the third week of March 2021. Some of it, $282 million, was distributed immediately, and the other $340 million was appropriated by the state legislature at a later date.

2020
During the week of March 16, 2020, Michigan Medicine started in-house testing for COVID-19, with the capabilities to deliver same-day results. This allowed the hospital to bypass the state's testing system, which was previously the sole provider of testing for the virus. The same week, the health system also launched drive-thru testing services for Michigan Medicine patients at West Ann Arbor Health Center, Brighton Health Center, and Canton Health Center.

Similarly, Beaumont Health and Henry Ford Health System in Metro Detroit also developed in-house testing methods in an effort to increase overall testing capacity within the state. On March 27, a regional drive-up testing center opened in Detroit, at the vacant State Fairgrounds site, which was able to test up to 400 residents a day. The state restructured reporting procedures and began incorporating private test results in official government case tallies on March 19.

Starting April 13, 2020, new testing sites opened in Atlanta, Bad Axe, Bay City, Battle Creek, Benton Harbor, Detroit, Flint, Jackson, Kalamazoo, and Traverse City.

On April 15, Hurley Medical Center in Flint opened a mobile testing clinic at Atwood Stadium, with capacity for at least 250 people per day. Testing was provided to those with orders from a doctor and was not open to the general public. Similar drive-thru testing facilities opened in Atlanta, Bad Axe, Battle Creek, Bay City, Benton Harbor, Dearborn, Grand Rapids, Jackson, Kalamazoo, Lansing, Saginaw, and Traverse City.

The state health department released case counts and death tolls daily and updated recovered cases weekly. Reviews of the outcomes of reported COVID cases led to the discovery of unrecorded deaths on multiple occasions. These deaths were added to the daily toll when discovered, with the result that daily reported deaths did not always indicate the current state of the epidemic. Recovery from the disease was defined simply as surviving 30 days after first symptoms, with no review of actual health or hospitalization status. Starting May 29, families could get tested together in Kalamazoo.

Aviation
Michigan airports received a combined $256 million in federal aid to help ease economic hardship from the coronavirus crisis, funded by the CARES Act.

Starting March 13, 2020, Delta Air Lines, which has a major hub at Detroit Metropolitan Airport, said it would cancel all flights to Europe for 30 days, decreasing flights by 40% and grounding 300 planes. Delta had previously indicated it would reduce international flights by 20–25% and domestic flights by 10–15%. On April 28, Delta announced it was suspending flights to and from Flint, Lansing, and Kalamazoo and several other small hub airports across the country after losing $534 million in the first quarter of 2020 due to the pandemic. American Airlines ended service to 15 small airports, including Kalamazoo, starting October 7.

Similarly, Michigan-based Meijer reported a plan to hire 40–50 new seasonal employees per store to help meet public demand during the outbreak. Kroger announced that, starting the morning of March 23, all of its Michigan stores would be dedicating the first hour of business on Mondays, Wednesdays, and Fridays to seniors, expectant mothers, first responders, and those with compromised immune systems. The following week, Kroger announced it would hire up to 2,000 people in Michigan in response to the pandemic.

On March 30, Ford announced it will convert its Rawsonville Components Plant in Ypsilanti to produce GE/Airon Corporation Model A-E ventilators. It says it will produce 50,000 ventilators in the next 100 days.

On April 1, General Motors announced it will produce 30,000 V+Pro critical care ventilators for the national stockpile.

2020
On the morning of March 16, Governor Whitmer announced a temporary order to close all bars and restaurants in the state to sit-down service, effective at 3 pm the same evening until March 30. Carry-out and delivery options were excluded from the order, although restaurants were urged to limit in-building carry-out services to five customers at a time. The order also included fitness centers, theaters, casinos, and other venues that encourage large assemblages of patrons, with several exceptions, such as office buildings. This order is expected to have significant economic impacts on businesses, and it prompted the Michigan Restaurant and Lodging Association to call for Whitmer to submit paperwork to qualify Michigan for the U.S. Small Business Administration Economic Injury Disaster Loan program. The order also expands unemployment benefits to public health workers who become ill, people who need to take time off to care for children, and others, until April 14.

Domino's Pizza, which is centered in the state, anticipated hiring up to 10,000 people to help meet increased demand for food delivery services due to the pandemic, while Jet's Pizza also prepared to hire "hundreds" of additional delivery drivers for the same reason.

The Michigan Unemployment Insurance Agency (UIA) had processed over 1.7 million applications as of May 13, with 1.375 million people receiving benefits. The state has paid $5.62 billion in benefits since the state of emergency was declared two months prior. By June 19, UIA disbursed $11.4 billion to two million people since the coronavirus pandemic reached the state.

Players reported to training camps at their regular season home stadiums on July 1 in order to resume spring training, which included inter-squad games only, and prepare for a July 23 or 24 Opening Day (July 24 for the Tigers). In an effort to slow the spread of the virus, teams only played their own division and the opposite league's corresponding geographical division, e.g. the Tigers only played the American League Central (40 games total) and National League Central (20 games total). Games were played behind closed doors, with artificial crowd noise played over loudspeakers.

The Tigers' August 3–6 series against the St. Louis Cardinals was postponed several times after 17 of the latter's members tested positive for COVID-19, with two of the games later cancelled outright.

Protests
On April 15, a convoy of thousands of motorists drove from all over the state to protest the extension of Governor Gretchen Whitmer's stay-at-home order. The protest, known as Operation Gridlock, involved clogging the streets surrounding on near the Michigan State Capitol, including the Capitol Loop, with their vehicles, drawing national attention. The protest was organized by the Michigan Conservative Coalition, a group with ties to the DeVos family, through Facebook. The Michigan Freedom Fund supported the rally by as an event co-host, spending an estimated $250 to promote the event. The organizers urged participants to practice social distancing, and not leave their vehicles during the protest. Lt. Darren Green of the Michigan State Police estimated several thousand cars were part of the demonstration, with 100 to 150 people congregating on the Capitol lawn. Neither the Michigan State Police nor the Lansing Police Department reported any arrests. Multiple services were disrupted as a result of Operation Gridlock, such as the Capital Area Transportation Authority (CATA) temporarily suspending their downtown route. Governor Whitmer said the protest was legal per the First Amendment's right to freedom of assembly, and understood the protesters' anger, but warned them they were endangering their health by not following social distancing guidelines. President Donald Trump supported the protest on April 17 with an all-caps tweet saying "Liberate Michigan".

On April 30, a second protest occurred when hundreds of protesters, many carrying firearms, gathered at the Michigan Capitol. Many protesters were able to enter the building. The demonstration was organized by conservative group Michigan United for Liberty. Governor Whitmer said on April 30 that she found elements of the protest 'disturbing.' Also, in an appearance May 3 on CNN's State of the Union, the governor said the Confederate flags, nooses and Nazi signs displayed were 'outrageous' and racist, with some depicting her as Adolf Hitler. On May 14, more armed protesters from Michigan United for Liberty gathered outside the Michigan State Capitol. The organization's Facebook group was deleted over death threats against Governor Whitmer and a fight broke out over a doll tied to a noose carried by a man who also had an axe at the protest. The Michigan Legislature closed its scheduled session to avoid the possibility of another armed confrontation inside the chamber.

On May 20, the Michigan Conservative Coalition held "Operation Haircut" on the lawn of the Capitol Building, in which barbers gave free haircuts, in support of an Owosso barber who was forced to shut down after continuing to operate until the previous week, violating the executive order closing non-essential businesses that included barbershops and beauty salons resulting in the state suspending his license. Several of the barbers at the demonstration were issued $1,000 citations by the Michigan State Police for disorderly conduct. A week later on May 27, the group from Operation Haircut delivered a letter to the Governor with a layout of safe practices to reopen. The charges against the Owosso barber were eventually dismissed. The charges against the other barbers arrested during the Operation Haircut demonstration were dismissed on February 8, 2021.

A peaceful demonstration of prayers organized by the religious non-profit Transformation Michigan was performed on the Capitol lawn on May 28. A peaceful protest called "Let MI People Go" by the religious group Stand Up Michigan took place on the Capitol lawn on October 8.

On December 15, a protest took place near the home of Robert Gordon, the director of the Michigan Department of Health and Human Services, to oppose the new restrictions imposed by the state.

Gretchen Whitmer kidnapping plot
During the summer and fall of 2020, Governor Whitmer was targeted with an elaborate kidnapping plot. The plot was revealed when the Federal Bureau of Investigation thwarted it. In October 2020, fourteen members of a right-wing militia group called the Wolverine Watchmen were charged with several federal and state crimes. One of the suspects cited Whitmer's handling of the pandemic as part of their motive to kidnap her.

Lawsuits
In April, multiple lawsuits were filed challenging Whitmer's executive orders. The suits were filed by individuals, business owners, recreational fishermen, a conservation organization, and several county prosecutors. They alleged that her orders were overly broad, violated their constitutional rights, harmed businesses, and amounted to an unconstitutional taking of property rights. Governor Whitmer's third stay-at-home order, issued April 24, overturned the restrictions on recreational boating and visits to vacation homes, effectively ending some of the lawsuits.

Emergency powers lawsuit
On May 6, Michigan House of Representatives Speaker Lee Chatfield and Michigan Senate Majority Leader Mike Shirkey, both Republicans, sued Governor Whitmer, who is a Democrat, over her use of emergency powers during the pandemic, saying only the Michigan Legislature has the power to extend the state of emergency. The Michigan Court of Claims ruled in Governor Whitmer's favor on May 21. The Michigan Court of Appeals affirmed the Court of Claims' ruling on August 21, in a 2–1 decision.

On October 2, the Michigan Supreme Court ruled on questions posed by District Judge Paul Lewis Maloney over whether Governor Whitmer violated the state Emergency Management Act of 1976, and whether the Emergency Powers of Governor Act of 1945 was unconstitutional. It was argued that Whitmer bypassed a requirement for a vote by the state legislature in order to extend a state of emergency beyond 28 days, by redeclaring it each time it expired. It was also argued that the Emergency Powers of Governor Act constituted an "unlawful delegation of legislative power to the executive". The court unanimously ruled against Whitmer on the former question. The court ruled 4–3 against Whitmer on the latter question.

Michigan Senate Majority Leader Mike Shirkey warned that the decision "does not alter our collective responsibility to protect ourselves and others", and encouraged "bipartisan action to transition from government operating in fear of the virus to government managing life in the presence of the virus." Governor Whitmer argued that the decision was still subject to a 21-day reconsideration period, during which the orders should have still stood. On October 4, Michigan Attorney General Dana Nessel stated that she would stop enforcing COVID-19-related executive orders. On October 5, Governor Whitmer told CNN the decision "undermined my emergency rule, my emergency orders that I've had to enact that puts us in the same state as all other states in this nation, to save lives. We've saved thousands of lives."

In response to the ruling, the Michigan Department of Health and Human Services (MDHHS) issued various orders intended to supplant most of Whitmer's executive orders, including requiring bars to close indoor gathering spaces, restrict the size of gatherings, and require the use of face masks in "social gatherings", defined as a shared space with two or more people where people are from multiple households. Businesses and government offices are required to enforce the requirements for gatherings on their premises. It also requires mask use in all sports except swimming if social distancing is not being practiced. These orders were enacted under the state health code, which gives the director of the HHS the authority to restrict gatherings and "establish procedures" to control an epidemic. The Michigan Occupational Safety and Health Administration similarly issued its own set of emergency rules for workplaces on October 14, again supplanting Whitmer's orders.

On October 12, the Court denied Whitmer's motion for a transition period, officially voiding all executive orders she had issued.
