Direct answer
The short answer for Phoenix, AZ
In Phoenix, desert heat, stucco homes on concrete slabs, swamp coolers in older houses, and large HOA communities shape what a late discovery looks like. The body breaks down fast indoors. Fluid soaks deep into soft materials. Odor escapes into shared attic or hallway spaces. This page is a planning guide. It covers how far fluid soaked in, the paths air takes through the AC and cooler, working with the estate and landlord, privacy, and records. Nothing here invents Phoenix ordinances or promises that a crew is nearby.

Local planning context
Most Phoenix homes are built on concrete slabs, with stucco outside, tile roofs, and carpet or vinyl inside. Many sit in HOA communities with rules on looks and staging. When someone dies alone in a closed, air-conditioned house and is not found for days, the extreme summer heat makes the body break down much faster. Carpet pad and particle-board furniture fail quickly. Fluid can reach the bottom wall boards and cabinet spaces while the yard outside still looks normal. Focus first on the sources inside. Opening the house to the outdoors does little once the pad is soaked.
Older Valley neighborhoods may still use swamp coolers, which push large amounts of air through ducts or window units. That air can spread smell from room to room in a different way than regular AC. If the returns leak, the attic above a hot ceiling can become a second pocket of odor. Insects still matter in a dry climate, because body fluids bring moisture indoors. Gated HOA communities add steps to get in, like codes, guard notes, and limits on dumpster spots. Those steps affect how quietly soiled materials can leave after release.
The Maricopa County Medical Examiner and any police hold control when cleanup can start. Once Maricopa County releases the home, the landlord and the estate should settle who gets which belongings. This matters in the many investor-owned rentals across the Valley. On tight lot lines, neighbors watch the driveway, so plan for privacy. Record the HOA limits, moisture findings, and what was removed. Then the rebuild crew starts with a clean, dry base and does not paint over a smell that was never fixed.
