Organization, Consolidation and Presentation of Financial Statements Disclosure and Significant Accounting Policies [Text Block]	Note A – Basis of Presentation The accompanying unaudited financial statements of Century Properties Fund XIX, LP (the "Partnership" or "Registrant") have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 8-03 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. The general partner of the Partnership is Fox Partners II, a California general partnership. The general partners of Fox Partners II are Fox Capital Management Corporation ("FCMC" or the "Managing General Partner"), a California corporation and Fox Realty Investors ("FRI"), a California general partnership. The Managing General Partner is a subsidiary of Apartment Investment and Management Company ("Aimco"), a publicly traded real estate investment trust. In the opinion of the Managing General Partner, all adjustments (consisting of normal recurring items) considered necessary for a fair presentation have been included. Operating results for the three and nine month periods ended September 30, 2011 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2011. The balance sheet at December 31, 2010 has been derived from the audited financial statements at that date but does not include all of the information and disclosures required by generally accepted accounting principles for complete financial statements. For further information, refer to the financial statements and footnotes thereto included in the Partnership's Annual Report on Form 10-K for the fiscal year ended December 31, 2010. The Partnership’s management evaluated subsequent events through the time this Quarterly Report on Form 10-Q was filed. Organization: On July 28, 2011, the Partnership entered into an agreement and plan of merger (the “Merger Agreement”) with AIMCO Properties, L.P., a Delaware limited partnership and AIMCO CPF XIX Merger Sub LLC, a Delaware limited liability company of which AIMCO Properties, L.P. is the sole member (the “Merger Subsidiary”), pursuant to which the Merger Subsidiary will be merged with and into the Partnership, with the Partnership as the surviving entity. In the merger, each unit of limited partnership interest (each, a “Unit”) of the Partnership outstanding immediately prior to the consummation of the merger (other than Units held by limited partners who perfect their appraisal rights pursuant to the Merger Agreement) will be converted into the right to receive, at the election of the limited partner, either (i) $352.02 in cash (the “Cash Consideration”) or (ii) a number of partnership common units of AIMCO Properties, L.P. calculated by dividing $352.02 by the average closing price of Aimco common stock, as reported on the New York Stock Exchange, over the ten consecutive trading days ending on the second trading day immediately prior to the effective time of the merger. However, if AIMCO Properties, L.P. determines that the law of the state or other jurisdiction in which a limited partner resides would prohibit the issuance of partnership common units of AIMCO Properties, L.P. in that state or other jurisdiction (or that registration or qualification in that state or jurisdiction would be prohibitively costly), then such limited partner will only be entitled to receive the Cash Consideration for each Unit. Those limited partners who do not make an election will be deemed to have elected to receive the Cash Consideration. After the merger, AIMCO Properties, L.P.’s membership interest in the Merger Subsidiary will be converted into Units of the Partnership. As a result, after the merger, AIMCO Properties, L.P. will be the sole limited partner of the Partnership, holding all outstanding Units. Fox Partners II will continue to be the general partner of the Partnership after the merger, and the Partnership’s partnership agreement in effect immediately prior to the merger will remain unchanged after the merger. Completion of the merger is subject to certain conditions, including approval by a majority in interest of the limited partners holding Units. In addition, the terms of the merger may be modified before the merger is completed. As of September 30, 2011 and December 31, 2010, there were issued and outstanding 89,274 Units, and AIMCO Properties, L.P. and its affiliates owned 60,711.66 of those Units, or approximately 68.01% of the number of Units outstanding. Approximately 25,228.66 of the Units owned by an affiliate of AIMCO Properties, L.P. are subject to a voting restriction, which requires the Units to be voted in proportion to the votes cast with respect to Units not subject to this voting restriction. AIMCO Properties, L.P. and its affiliates have indicated that they will vote all of their Units that are not subject to this restriction, approximately 35,483 Units or approximately 39.75% of the outstanding Units, in favor of the Merger Agreement and the merger. As a result, affiliates of AIMCO Properties, L.P. will vote a total of approximately 49,460 Limited Partnership Units, or approximately 55.40% of the outstanding Units in favor of the Merger Agreement and the merger. AIMCO Properties, L.P. and its affiliates have indicated that they intend to take action by written consent to approve the merger. Net Loss Per Limited Partnership Unit: Net loss per limited partnership unit is computed by dividing net loss allocated to the limited partners by the number of Units outstanding at the beginning of the fiscal year. The number of Units used was 89,274 and 89,276 for the three and nine months ended September 30, 2011 and 2010, respectively.
