Come up with a good organizing system before you amass much data. Create multiple folders
and rename digital files for easy searching and retrieval. For example, if you put the date at the
front of the file name in YEAR-MONTH-DAY format, everything will automatically sort
chronologically. Also add keywords to the file name for quick searches across different folders.
ORAL HISTORY & CENSUS RECORDS
Interview neighbors, previous owners, or relatives of these families. Many of the historic homes
in Hawaii were built during the first half of the twentieth century, so they are associated with
people and communities which still are able to provide first-hand information.
Put together a list of names of people associated with the house, such as former neighbors, family
friends, housekeepers, relatives, etc. An internet search may give you information to help locate
some of these people. Some information they may be able to provide include colors of the house
inside and out; type and placement of the furniture; uses of various rooms; and stories about its
occupants. One of the most important things you may find are old photos of the house.
DEPARTMENT OF PLANNING AND PERMITTING
To begin your research, you will need the residence’s street address and Tax Map Key (TMK)
number. You can find a residence’s TMK number on the Real Property Tax Bill. Use the TMK
number to find the permit history for your residence. Building permit records help you find the
dates of alterations made to the house, the type of alterations, the name of the owners, name
of the architect and builder, cost, floor plans that show the location of major fixtures, and types
of materials.
In Honolulu, this information may be found on-line on the website for the Department of
Planning and Permitting for the City & County of Honolulu:

The Geographic Information System (GIS) option allows you to search either by address or TMK
number. The zoning information will tell you if the residence is already on the “historic site
register.” Building permits issued prior to January 1972, however, are not available on-line. Copies
of the building permits may be obtained by visiting the Data Access and Imaging Branch on the
first floor of the Honolulu Municipal Building at 650 South King Street, tel. (808) 527-6743 or
COUNTY REAL PROPERTY TAX ASSESSEMENT OFFICE
A residence’s real property tax records help you establish the “chain of title” history that shows
who owned the residence and when ownership transfers occurred.
On the summary tax sheet for the residence, each transfer of ownership is recorded. On the same
line as the transfer, there is a document number that will help you locate the deed book in which
