Direct answer
The short answer for San Diego, CA
San Diego is a coastal metro, with about 1,390,000 people in the city itself. It mixes bungalows under the marine layer, apartments in Mission Valley and Mira Mesa, homes on slabs along canyon rims, and rentals near military bases. Cool mornings near the water keep windows shut. Inland valleys run the AC hard by afternoon. Each kind of home traps the smell of a late discovery in its own way.

Local planning context
Homes stretch from cottages in Point Loma and Pacific Beach to slab houses in Clairemont and Serra Mesa, then into hotter inland areas toward Kearny Mesa and Otay. A person living alone may go unnoticed until a neighbor, a commanding officer's welfare check, or an unpaid utility notice leads someone inside. By then, body fluid has often wicked through the carpet pad into the underlayment. Meanwhile, the marine layer kept the outer doors shut against fog and for security. Canyon-rim houses on several levels add the risk of fluid dripping into a den or carport below. Name the building type first: slab, short crawl space, or hallway apartment. Do that before anyone suggests cutting out just a square of carpet.
The weather splits the metro. On the coast, mornings feel mild outside, yet homes stay sealed. Odor chemicals build up in closed bedrooms even when the sidewalks stay cool. Inland valleys get warm enough that people run forced-air cooling for long stretches. If no one closes off the returns, the smell cycles through them. Families sometimes open the lanai sliders to air out the unit while wet mattresses are still inside. That thins the hallway smell for a bit, but it can push odor into the breezeways of garden apartments. Blankets shoved into a complex's storage closet can keep smelling after the unit is clean. Flies gathered on sunny windows point to a longer gap, which is common in empty rentals after a military transfer.
Work in city neighborhoods from Point Loma to Rancho Bernardo waits on the county examiner and police. Managers with buildings farther north should not assume the same contacts apply here. Landlords who rent to military families, and families who may be stationed far away, should agree by email on what is saved. On tourist and beach blocks, privacy means covered carts and short times at the curb. Keep photo lists and material lists that work for a probate lawyer and insurers. Treat scent or ozone machines as extras, used only after the soaked materials have left the property.
