Parcel updates occur at DPW.
Every week night an automated ETL runs that updates EAS parcels from DPW.

All other fields may be updated, including the geometry.
Parcel Retirement - DPW
Parcel retirement occurs at DPW.
Parcel retirement is a special kind of update.
Every week night an automated extract-transform-load (ETL) job retires parcels in EAS based on data from DPW.
If a parcel is newly retired, addresses that are linked to the retired parcel are marked as "invalid".
You can read more about invalid addresses here.
The DPW process for retiring parcels is non-trivial trivia and is documented here (need link).
