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 with a satellite office located in Bergen 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 nine banking offices, eight located in Sussex County, New Jersey and one in Orange County, New York. 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 the 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 three month period ended March 31, 2014, are not necessarily indicative of the results that may be expected for the year ending December 31, 2014. 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, 2013. We have evaluated events and transactions occurring subsequent to the balance sheet date of March 31, 2014, 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 July 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, which provides guidance on financial statement presentation of an unrecognized tax benefit when a net operating loss (NOL) carryforward, a similar tax loss, or a tax credit carryforward exists. The FASB’s objective in issuing this ASU is to eliminate diversity in practice resulting from a lack of guidance on this topic in current U.S. GAAP. This ASU applies to all entities with unrecognized tax benefits that also have tax loss or tax credit carryforwards in the same tax jurisdiction as of the reporting date. For public entities, the guidance is effective for fiscal years beginning after December 15, 2013 and interim periods within those years. The adoption of this guidance did not have a material impact on our consolidated financial statements.
