Ask a hauler in Maricopa County what makes demolition debris removal tricky and they'll point to structural material coming down faster than any other phase of a job produces it. demolition and general contractors tend to be the ones filling out the Cashion request form. The company that answers for Cashion is likely working out of Maricopa County, with Southwest filling in the rest of its territory.
A container headed to Cashion is coming out of an existing route through Maricopa County, not a dedicated trip. Nothing in a remodel tear-out is dense on its own, but stacked together it adds up fast, so the container fills toward its weight limit well before the sides do. If the driveway is concrete or newly paved, ask whether boards go under the container -- a rolled-off container can crack a surface that looks solid enough to hold it.
The fine print that matters most locally is older structures need testing before demolition, because contaminated debris cannot be containerised, not the rental length. Weather in Arizona, specifically desert heat with a summer monsoon season, is the quiet reason booking gets harder some months and easier others. The age of housing across Southwest, mostly 1970s-2000s tract housing across the metros, changes what a typical container ends up holding. Maricopa County sizing for demolition debris lands on 30 or 40 yards more often than not, driven by load weight rather than the footprint of the job. Keep the container in the driveway and you skip the paperwork entirely; put it at the curb and you'll need municipal right-of-way permits and heavy HOA involvement. A gravel or dirt surface holds a container differently than sidewalk does; ask whether that changes where it can be placed.
