     This Amendment No. 31 (this “Amendment”) amends the Statement on Schedule 13D (as amended, the “Statement”) filed previously with the Securities and Exchange Commission by AIMCO Properties, L.P., AIMCO-GP, Inc., Apartment Investment and Management Company, AIMCO IPLP, L.P., AIMCO/IPT, Inc. and IPLP Acquisition I, LLC (collectively, the “Reporting Persons”).

Item 4. Purpose of Transaction

Item 4 is hereby supplemented by the addition of the following information:

Fox Partners IV, a California general partnership (the “General Partner”), is the general partner of the issuer, Century Properties Growth Fund XXII, a California limited partnership (the “Partnership”). The General Partner is an affiliate of the Reporting Persons. On September 18, 2008, the General Partner proposed that the Partnership change its domicile from California to Delaware (the “Redomestication”). The General Partner proposes to effect the Redomestication through a merger of the Partnership with and into Century Properties Growth Fund XXII, LP, a Delaware limited partnership (the “Delaware Partnership”), with the Delaware Partnership as the surviving entity in the merger.

In the merger, each unit of limited partnership interest in the Partnership would be converted into an identical unit of limited partnership in the Delaware Partnership and the general partner’s interest in the Partnership would be converted into an equivalent interest in the Delaware Partnership. All interests in the Delaware Partnership outstanding immediately prior to the merger would be cancelled in the merger. The voting and other rights of the limited partners provided for in the Partnership’s existing Limited Partnership Agreement would not be changed as a result of the merger.

In the merger, the Partnership’s existing Limited Partnership Agreement would be adopted as the partnership agreement of the Delaware Partnership, with the following changes: (i) references therein to the California Uniform Limited Partnership Act would be amended to refer to the Delaware Revised Uniform Limited Partnership Act; (ii) a description of the merger would be added; (iii) the name of the partnership would be changed to “Century Properties Growth Fund XXII, LP” and (iv) a provision would be added that would give the general partner authority to establish different designated series of limited partnership interests that would have separate rights with respect to specified partnership property, and profits and losses associated with such specified property.

The merger must be approved by the general partner of the Partnership and a majority in interest of the limited partners. The general partner’s affiliates (including the Reporting Persons), which own a majority of the outstanding units of limited partnership interest in the Partnership, have indicated that they intend to take action by written consent to approve the merger as soon as practicable at least 20 calendar days after an Information Statement has been distributed to limited partners of the Partnership. As a result, approval of the merger is assured, and no other limited partner’s consent to the merger would be required.
