Permit Database Information – Permits Plus

PRMD uses the Permits Plus database system to track the many types of permits and activities processed at PRMD. The public can view PRMD activities and permits through the permit history application and the Accela Citizen Access™ Permit Manager website. When looking at PRMD records it is helpful to be familiar with certain codes used in this system. This page provides links to documents that are helpful in interpreting PRMD's records both historical and current.

Area ID

The county is divided into geographic areas for the purposes of various types of inspections that PRMD staff performs. These areas are named for communities but are not necessarily contiguous with any individual community boundary due to aggregation of several communities into the larger area. These areas are called Area IDs and are appended to the address attached to a permit. Three character IDs indicate unincorporated areas and two character IDs are incorporated cities. A more detailed definition can be found on our PRMD Area ID map Acrobat Document.

You must use the correct Area ID to find permits by address on the Accela Citizen Access™ site.

FileTypes (aka Permit Types)

PRMD processes many types of applications and permits. As of July 1, 1999, the first three characters of the file number indicate FileType Acrobat Document (aka Permit Type). A variety of number schemes were used on historical files which can be found in Permits Plus.


PRMD files track a wide variety of land development activities. Statuses Acrobat Document have been modified through time, to better identify milestones during the life span of a specific FileType. Many historical files reflect statuses which are no longer in use.

Street Names

PRMD maintains a list of valid street names and corresponding Area IDs for its permitting activity with Permits Plus. When searching for an address in any of PRMD's records a valid street name must be used.


Each permit or activity type processed by PRMD has a subtype code Acrobat Document attached that specifies what type of project the permit or activity represents. These subtypes are unique to the different types of permits or activities.

Although every effort is made to provide complete and accurate information on this website, users are advised to contact appropriate PRMD staff before making project decisions. This may involve contacting more than one section within PRMD (e.g. Building, Plan Check, Zoning, Well & Septic, etc.), since each section implements specific codes or ordinances which may affect your project.
