Attorney General Mayes Sues Out-of-State Landlords for Leaving Tucson Tenants Without AC in Summer Heat
TUCSON – Attorney General Kris Mayes today announced a lawsuit filed in Maricopa County, against the owners and managers of three affiliated apartment complexes in Tucson: Sedona Springs, Sienna Ridge, and Summit Ridge. The complexes house over one thousand units combined.
The lawsuit was filed August 7, 2026 against the three complexes' respective owners, members, and managers: Sedona Springs AZ, Sienna Ridge AZ, Summit Ridge AZ, DMR Sedona Springs AZ, DMR Tucson 1166, and Tucson 1166 IG, as well as Dasmen Residential and Luxford Living.
"All Arizona residents who enter into rental agreements deserve living conditions that meet minimal standards of habitability," said Attorney General Mayes. "The ongoing neglect Dasmen Residential and Luxford Living continue to display by failing to supply adequate air conditioning to residents at Sedona Springs, Sienna Ridge, and Summit Ridge puts residents' lives at serious risk, especially during extreme summer heat.”
The complaint and application for a temporary restraining order and preliminary injunction allege a pattern of neglect and deception by the owners and operators of Sedona Springs, Sienna Ridge, and Summit Ridge dating back to at least 2023.
This summer alone, tenants at all three properties have struggled to cool their homes to the required Pima County standard of 80 degrees Fahrenheit or less. In fact, half of Sedona Springs has gone without central air of any kind since March. Those tenants have been left to rely on temporary, portable window units that often fail to cool more than one room in the apartments they pay to live in — even as Arizona once again faces record-breaking summer temperatures. As a result, indoor temperatures at Sedona Springs, Sienna Ridge, and Summit Ridge have often exceeded 90 degrees Fahrenheit.
Attorney General Mayes previously issued cease-and-desist letters to each of the properties in 2026, requiring the owners and operators to fix the ongoing habitability concerns. However, temporary fixes — such as the previously installed window units — have not proven adequate for all tenants.
The complaint alleges that all three complexes suffer from a pattern of neglect, including broken windows, water and gas issues, structural problems, and pest infestations — none of which are disclosed to prospective tenants before they sign a lease. These practices potentially violate the Arizona Consumer Fraud Act and the Arizona Residential Landlord and Tenant Act.
Attorney General Mayes is seeking a permanent injunction requiring the owners and operators of all three properties to make necessary repairs to comply with Arizona law, as well as a permanent injunction barring the defendants from renting to Arizona consumers until their units meet legal requirements. The complaint also seeks restitution and civil penalties for the harm caused to residents.
