Summary Of Significant Accounting Policies [Abstract]
Basis Of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements include the accounts of Sussex Bancorp ("we," "us" or "our") and our wholly-owned subsidiary Sussex Bank (the "Bank"). The Bank's wholly-owned subsidiaries are SCB Investment Company, Inc., SCBNY Company, Inc., ClassicLake Enterprises, LLC, Wheatsworth Properties Corp., PPD Holding Company, LLC, and Tri-State Insurance Agency, Inc. ("Tri-State"), a full service insurance agency located in Sussex County, New Jersey. Tri-State's operations are considered a separate segment for financial disclosure purposes. All inter-company transactions and balances have been eliminated in consolidation. The Bank operates ten banking offices, eight located in Sussex County, New Jersey and two in Orange County, New York. In 2011, we opened a loan production and insurance agency satellite office in Rochelle Park, New Jersey. Sussex Bancorp is subject to the supervision and regulation of the Board of Governors of the Federal Reserve System (the "FRB"). The Bank's deposits are insured by the Deposit Insurance Fund ("DIF") of the Federal Deposit Insurance Corporation ("FDIC") up to applicable limits. The operations of Sussex Bancorp and Sussex Bank are subject to the supervision and regulation of the FRB, FDIC and the New Jersey Department of Banking and Insurance (the "Department") and the operations of Tri-State are subject to supervision and regulation by the Department. The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information. Accordingly, they do not include all of the information and footnotes required by the accounting principles generally accepted in the United States of America ("U.S. GAAP") for full year financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation have been included and are of a normal, recurring nature. Operating results for the six month period ended June 30, 2012, are not necessarily indicative of the results that may be expected for the year ending December 31, 2012. These unaudited consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto that are included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2011. We have evaluated events and transactions occurring subsequent to the balance sheet date of June 30, 2012, for items that should potentially be recognized or disclosed in these unaudited consolidated financial statements. The evaluation was conducted through the date these unaudited consolidated financial statements were issued.
Reclassifications	Reclassifications Certain amounts in the prior period financial statements have been reclassified to conform to the current period presentation. These reclassifications had no effect on previously reported net income.
New Accounting Standards	New Accounting Standards In December, 2011, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2011-11, Disclosures about Offsetting Assets and Liabilities, in an effort to improve comparability between U.S. GAAP and International Financial Reporting Standards ("IFRS") financial statements with regard to the presentation of offsetting assets and liabilities on the statement of financial position arising from financial and derivative instruments, and repurchase agreements. The ASU establishes additional disclosures presenting the gross amounts of recognized assets and liabilities, offsetting amounts, and the net balance reflected in the statement of financial position. Descriptive information regarding the nature and rights of the offset must also be disclosed. The new standards are effective for annual periods beginning January 1, 2013, and interim periods within those annual periods. Retrospective application is required. We do not expect that the adoption of this guidance will have a material impact on our consolidated financial statements.
