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 and six month periods ended June 30, 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 June 30, 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. In January 2014, FASB issued ASU 2014-04, Receivables - Troubled Debt Restructurings by Creditors, which clarifies that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either (1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additionally, the amendments require interim and annual disclosure of both (1) the amount of foreclosed residential real estate property held by the creditor and (2) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. For public entities, the guidance is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements. In May 2014, FASB issued ASU 2014-09, Revenue from Contracts with Customers. The ASU’s core principle is built on the contract between a vendor and a customer for the provision of goods and services. It attempts to depict the exchange of rights and obligations between the parties in the pattern of revenue recognition based on the consideration to which the vendor is entitled. To accomplish this objective, the standard requires five basic steps: i) identify the contract with the customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract, and (v) recognize revenue when (or as) the entity satisfies a performance obligation. For public entities, the guidance is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2016. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements. In June 2014, FASB issued ASU 2014-11, Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures, to change the accounting for repurchase-to-maturity transactions and certain linked repurchase financings. This will result in accounting for both types of arrangements as secured borrowings on the balance sheet, rather than sales. Additionally, the ASU introduces new disclosures to (i) increase transparency about the types of collateral pledged in secured borrowing transactions and (ii) enable users to better understand transactions in which the transferor retains substantially all of the exposure to the economic return on the transferred financial asset throughout the term of the transaction. For public entities, the disclosure for repurchase agreements, securities lending transactions, and repurchase-to-maturity transactions accounted for as secured borrowings is required to be presented for annual periods beginning after December 15, 2014, and for interim periods beginning after March 15, 2015. All other accounting and disclosure amendments in the ASU are effective for public business entities for the first interim or annual period beginning after December 15, 2014. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements. In June 2014, FASB issued ASU 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period (a consensus of the FASB Emerging Issues Task Force), to clarify that a performance target in a share-based compensation award that could be achieved after an employee completes the requisite service period should be treated as a performance condition that affects the vesting of the award. As such, the performance target should not be reflected in estimating the grant-date fair value of the award. For all entities, the amendments are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Earlier adoption is permitted. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements.
