10 Ariz. Admin. Code § R10-2-120

A. Upon the filing of a complaint under R10-2-115, the Attorney
General shall initiate an investigation to:
1. Obtain information concerning the events or transactions
that relate to the alleged discriminatory housing practice
identified in the complaint;
2. Document policies or practices of the respondent
involved in the alleged discriminatory housing practice
arising out of the complaint or the investigation of the
complaint;
3. Obtain information concerning and document policies or
practices of housing discrimination which suggest that
the respondent is currently engaging in other housing
practices or policies which are in violation of the Act; and
4. Develop factual data necessary for the Attorney General
to make a determination under R10-2-124 whether reasonable cause exists to believe that a discriminatory housing practice has occurred or is about to occur, and to take
other actions provided for under this Act.
B. During the course of this investigation, the Attorney General
may develop data by formal and informal means including
propounding interrogatories, conducting formal and informal
interviews of witnesses, conducting on-site inspections of the
property and dwelling, and issuing subpoenas and subpoenas
duces tecum.
1. Interrogatories: The Attorney General’s office may cause
to be issued interrogatories upon any person. Interrogatories issued pursuant to this rule shall require that the person to whom the interrogatories are addressed answer
those interrogatories under oath or affirmation. Interrogatories issued pursuant to this rule shall be answered and
returned to the Attorney General’s Office within 14 days
of the receipt of the interrogatories except that any person
served with such interrogatories may request of the Attorney General an extension of time in which to answer the
interrogatories. Such extension may be granted upon a
showing of good cause.
2. Subpoenas: The Attorney General may issue a subpoena
compelling the attendance and testimony of a witness or
requiring the production for examination or copying of
documents, provided such evidence relates to unlawful
practices covered by the Act and is relevant to the complaint which is being investigated or arises out of the
investigation of the complaint. Except upon good cause
or upon agreement of the witness, such subpoena shall
provide a minimum of five days’ notice before the witness must appear or produce documents. Within five days
after the service of a subpoena on any person requiring
the production of any evidence in the person’s possession
or control, such person may petition the Attorney General
to revoke, limit, or modify the subpoena. The Attorney

General shall revoke, limit, or modify such subpoena if in
its opinion the evidence required:
a. Does not relate to unlawful practices prohibited by
the Act;
b. Is not relevant to the complaint which is being investigated;
c. Does not describe with sufficient particularity the
evidence whose production is required; or
d. Is unduly burdensome or oppressive.
Witness interviews: All witness interviews may be under
oath or affirmation. Any member of the Attorney General’s office, or any agent designated by that office, may
administer oaths or affirmations, examine witnesses, and
receive evidence. Any person appearing before the Attorney General shall have the right to be represented by
counsel. The Attorney General may re-interview a witness. Testimony provided in connection with any investigation conducted pursuant to A.R.S. § 41-1491.24 may
be recorded by audio or video recording equipment,
stenographic means, or other devices. A person who submits data or evidence to the Attorney General may retain
or, on payment of lawful prescribed costs, procure a copy
or transcript, if available, of the data or evidence submitted by that witness. A person who testifies before the
Attorney General may obtain a copy of his or her own
testimony upon request and upon providing the Attorney
General with a blank audio or video tape of appropriate
length.
On-site inspections: Any representative of the Attorney
General’s office may enter upon a property or dwelling
which is the subject of a complaint of discrimination
under the Act at reasonable hours, for purposes of
inspecting such property or dwelling in connection with
such complaint.
Time periods: Any time periods established under subsection (B) shall be governed by Rule 6(a), Arizona Rules
of Civil Procedure (1993).
