The Tucson homelessness lawsuit is a legal dispute between the City of Tucson and residents of the Hedrick Acres neighborhood over homeless encampments in Navajo Wash Park.
The case began after nearby residents argued that the city was allowing a large homeless encampment to remain in the area despite complaints about trash, fires, drug activity, violence, and other problems. The residents asked the courts to require Tucson to take stronger action.
The case became important because it raised a difficult question facing many cities: How should a city balance the rights and needs of people experiencing homelessness with the rights of nearby residents and property owners?
In May 2025, the Arizona Court of Appeals issued a significant ruling in the case, allowing the neighborhood’s lawsuit to continue after reversing part of an earlier trial-court decision.
What Is the Tucson Homelessness Lawsuit About?
The lawsuit involves the Hedrick Acres Neighborhood Association and other nearby residents who challenged the City of Tucson’s handling of homeless encampments in Navajo Wash.
According to the Arizona Court of Appeals, homeless individuals began establishing encampments in the wash at least as early as 2019. By 2022, the area had developed more permanent tent encampments.
Nearby residents said the conditions became increasingly difficult.
They reported concerns involving:
- Trash and debris
- Makeshift toilets
- Fires
- Drug paraphernalia
- Violence and criminal activity
- Property and neighborhood impacts
- Repeated return of people after encampment cleanups
The residents argued that Tucson’s approach was not enough to address the problem.
Why Did Residents Sue Tucson?
The lawsuit was filed in September 2023.
The plaintiffs argued that the conditions in Navajo Wash amounted to a public and private nuisance and that the city’s policies had allowed the situation to continue.
They asked the court for an injunction requiring the city to immediately address the alleged nuisance.
The residents’ argument was not simply that homeless people were present.
Instead, they argued that the city had been aware of serious conditions in the area and had failed to adequately address them.
The city disagreed.
Tucson argued that it had adopted policies for dealing with homeless encampments and that it had taken reasonable steps, including providing services and conducting cleanups.
Tucson’s Three-Tier Encampment System
One of the important issues in the lawsuit was Tucson’s three-tier approach to homeless encampments.
According to the appellate court’s description, the city began using this system in 2022.
Tier 1: Former Encampments
Tier 1 locations are areas where homeless individuals are no longer living.
The city coordinates cleanup efforts at these locations.
Tier 2: Lower-Priority Encampments
Tier 2 locations involve encampments where people remain but the city considers the situation manageable.
The city provides outreach services and performs trash collection.
Tier 3: High-Problem Encampments
Tier 3 locations are considered high-problem encampments.
These locations can involve issues such as violence or criminal activity.
When an encampment reaches this level, Tucson can provide a 72-hour notice to vacate, address criminal behavior, offer services and clean the area.
The residents argued that the city’s system did not adequately solve the problems at Navajo Wash because people repeatedly returned after the encampments were cleared.
What Happened at Navajo Wash?
The appellate court noted that the Navajo Wash encampments had been monitored by Tucson since at least April 2023.
The location had reportedly reached the city’s Tier 3 classification at least 10 times between April 2023 and February 2024.
However, after the city cleared the area, homeless residents repeatedly returned.
That repeated cycle became a central issue in the lawsuit.
The neighborhood argued that simply clearing an encampment temporarily did not solve the underlying problem.
The city, meanwhile, maintained that it had a system for determining when intervention was appropriate and that it was taking steps to address the situation.
What Did the Trial Court Decide?
After a three-day bench trial, the trial court ruled against the residents’ request for an injunction.
The court determined that Tucson did not cause the homeless encampments and that the city’s three-tier policy did not itself create the alleged nuisance.
The trial court therefore denied the request for immediate injunctive relief.
However, the court also determined that the city was not immune from the lawsuit under the specific Arizona governmental-immunity statute raised in the case.
That distinction became important on appeal.
Why Did the Residents Appeal?
The neighborhood plaintiffs appealed because they wanted the city to be required to take stronger action regarding the Navajo Wash encampments.
Their basic position was that Tucson should not be able to avoid responsibility simply by pointing to its encampment policy.
They argued that the actual conditions in the wash—not merely the existence of a city policy—were creating a nuisance for nearby residents.
The appeal therefore focused on whether the trial court had applied the law correctly when it denied the requested relief.
What Did the Arizona Court of Appeals Decide?
The Arizona Court of Appeals, Division Two, issued its published decision in May 2025.
The appellate court’s decision was significant because it rejected the idea that the city’s policy alone resolved the residents’ claims.
The court examined whether the city could be held responsible for the alleged nuisance and whether the plaintiffs could pursue their claims.
The appellate decision did not simply order Tucson to eliminate homelessness from Navajo Wash.
Instead, it addressed the legal issues surrounding the residents’ claims and the city’s defenses.
This distinction is important because headlines about the case can make the ruling sound broader than it actually was.
Did the Court Order Tucson to Ban Homeless Encampments?
No.
The lawsuit does not mean that the Arizona Court of Appeals ordered Tucson to ban all homeless camping.
It also does not mean that every homeless person living in a Tucson public space must immediately be removed.
The case is much narrower.
It concerns the alleged conditions at Navajo Wash and whether the city can be held legally responsible for a nuisance arising from those conditions.
The court’s decision therefore should not be interpreted as a statewide ban on homeless encampments.
Why Is the Case Important?
The Tucson lawsuit is important because cities across Arizona and the United States are dealing with similar disputes.
Homeless encampments can create difficult conflicts involving:
- Public safety
- Property rights
- Public health
- Sanitation
- Criminal activity
- Access to shelters
- Housing availability
- Enforcement of camping laws
- Rights of people experiencing homelessness
Cities also have to decide how to use limited resources.
Simply removing an encampment may move people somewhere else without permanently solving homelessness.
On the other hand, allowing large encampments to remain for long periods can create serious problems for surrounding neighborhoods.
The Tucson case illustrates that tension.
Tucson’s Homelessness Problem in 2026
The legal dispute comes as Tucson continues to face significant housing and homelessness challenges.
In February 2026, the Tucson City Council formally declared a housing and homelessness emergency.
The emergency declaration was set to remain in effect for one year. City officials said the measure would make it easier to create additional shelter spaces, safe sleeping areas and safe parking sites.
The declaration came after the city’s public housing waitlists were closed in January 2026.
According to reporting from Arizona Public Media, the city said there were approximately 40,000 applicants and that housing everyone on the list could take a decade.
That context helps explain why the homelessness issue is much bigger than the Navajo Wash lawsuit.
What Does the Tucson Lawsuit Have to Do With the Supreme Court’s Grants Pass Decision?
Another important issue is the U.S. Supreme Court’s 2024 decision in City of Grants Pass v. Johnson.
The Supreme Court ruled that laws regulating camping on public property do not automatically violate the Eighth Amendment’s prohibition against cruel and unusual punishment simply because they apply to people experiencing homelessness.
The decision gave cities more legal room to enforce restrictions on camping in public areas.
However, it did not require every city to criminalize homelessness or adopt a particular policy.
Tucson therefore still has to decide how it wants to manage encampments while complying with federal and state law.
Is the Tucson Homelessness Lawsuit About Criminalizing Homelessness?
Not exactly.
The lawsuit is primarily about alleged nuisance conditions and the city’s responsibility for addressing them.
That is different from a criminal case against homeless individuals.
The residents sought legal action against the City of Tucson, arguing that the city was not adequately addressing conditions around the Navajo Wash encampment.
The case therefore focuses heavily on government responsibility and local policy.
What Could Happen Next?
The ultimate outcome depends on the continuing court proceedings and how the parties respond to the appellate ruling.
The case could potentially lead to additional legal proceedings over:
- Whether the alleged nuisance exists
- What responsibility the city has
- What remedies are legally available
- Whether Tucson’s encampment policies are sufficient
- How the city should respond to recurring encampments
At the same time, Tucson is pursuing broader homelessness policies outside the lawsuit, including additional shelter and safe-sleeping options following its 2026 emergency declaration.

Is the Tucson Homelessness Lawsuit Over?
Not necessarily.
The appellate decision was an important development, but the legal dispute does not mean that the homelessness problem in Navajo Wash—or Tucson more broadly—has been permanently resolved.
The city continues to deal with encampments and housing shortages.
In fact, Tucson’s 2026 homelessness emergency declaration shows that the city considers the broader problem serious enough to require additional measures.
Bottom Line
The Tucson homelessness lawsuit centers on a dispute between the City of Tucson and residents of the Hedrick Acres neighborhood over homeless encampments in Navajo Wash.
Residents sued the city in 2023, arguing that recurring encampments created a nuisance involving issues such as trash, fires, drug paraphernalia and criminal activity. Tucson defended its three-tier encampment policy and argued that it had taken reasonable steps to address the situation.
The case is important because it highlights the difficult balance between neighborhood safety, property rights, homelessness, public resources and the rights of people without permanent housing.
The broader situation remains active in Tucson. In February 2026, the city declared a one-year housing and homelessness emergency and announced plans to expand options such as shelters, safe sleeping sites and safe parking.
So, while the Navajo Wash lawsuit is a specific legal dispute, it is part of a much larger debate over how Tucson should respond to homelessness and public encampments.
