Listing Policy & Guidelines

CoStar Realty Information, Inc. and its affiliates (“We or “Us”), through its CoStar and LoopNet service, is providing you these Listing Policies and Guidelines (the "Listing Policies") for you to review and understand prior to you entering a property listing on the CoStar or LoopNet website, as applicable (collectively, the “Site”). All listings are subject to the Listing Policies.

Listing Service

By submitting content to the Site to advertise a property for sale or lease (the “Listing Service”), you represent and warrant that: (a) the property is eligible to be listed using the Listing Service, meaning the property is a commercial real estate property available for sale or lease; (b) you own or have the right to advertise the property you are listing; (c) you have the right to lease the advertised property; (d) you are willing to sell or lease the advertised property at the price and on any other terms specified in your listing; (e) you will not advertise more than one property in a single listing on the Listing Service, either by including descriptions of multiple units in one listing or by subsequently updating the listing information to advertise different properties or units; (f) upon selling or leasing or otherwise taking your property off the market, you will within 72 hours delete the listing for that property; (g) you will not use the Listing Service to advertise or promote anything, including, without limitation, any product, service or business, other than the unique property offered for sale or lease; (h) you will not use the Listing Service or the Site for any fraudulent, false, misleading or deceptive activity; (i) you are solely responsible for any and all listings you add using the Listing Service, and all ads, photos, descriptions, data, or other information (“Content”) you submit to the Site; (j) all Content that you provide to the Site and everything in your listing, including without limitation, any photos or text description, is truthful, accurate and complete and comply with all local, state and federal laws and regulations; (k) you have all the rights necessary to post your listings using the Listing Service, including, without limitation, all Content and other information contained therein, on the Site; and (l) photos you upload to the Listing Service will only show the property listed for rent and shall not include, under any circumstances, people, animals, trademarked items, religious symbols, or other objects or features not part of the property for sale or lease. By submitting Content for a property listing on the Site, you grant to Us a perpetual and irrevocable license to copy, modify, display, distribute, create derivative works from, or otherwise use and exploit such information that you submit. The permission you grant Us includes express permission to syndicate the Content to our affiliated or partner sites.

Listing Review and Management

All listings entered on the Site may be subject to review by our research team personnel ("Research Team”). We reserve the right, but not the obligation, to review any listing entered by you on the Site and enrich the listing by adding additional content. Although your listings may be subject to review by the Research Team, you remain solely responsible for abiding by the Listing Policies and LoopNet's Terms and Conditions and CoStar’s Terms of Use, as applicable (the “Site Terms”). The Listing Policies prohibit you from entering any listing that infringes upon the intellectual property rights of any party, or that otherwise violates the Site Terms. By entering listings on the Site, you warrant and represent that you owns or otherwise control all of the rights to such content, including, without limitation, all the rights necessary for you to provide, post, upload, input or submit such content. You acknowledge that We cannot police or control all of the content you provide that is made available on the Site.

New listings added to the Site from first time listers are examined to determine whether such listings are in compliance with the Listing Policies. In the event the Research Team determines a listing (new or otherwise) violates the Listing Policies (including, but not limited to, containing inaccurate or incomplete information), the Research Team will contact you about such listing stating how such listing does not conform to established Listing Policies and offering solutions on how to cure the violation. We, in our sole discretion, reserve the right to remove any and all content that violates the Listing Policies, including disallowing listings from the Site or removing duplicate or similar listings from the Site.

Required Fields

All fields noted by an asterisk (*) on the add property page are required fields and must be completed with valid data pertaining to the property being listed ("Required Fields"). Property listings where data is missing or data entered in the Required Fields is deemed illogical will be removed from the Site until valid content is entered in the Required Fields.  If you update a critical field that conflicts with the company’s property level data, the Research Team will review and approve/deny the updated value.  If denied, the value will revert to the company’s property level data value.

Address Fields

All address fields on the Site including Address, City, State and Zip Code are Required Fields. These fields are intended for listing the physical address in the United States, Canada, United Kingdom or Spain of the property being listed. In lieu of the address, an intersection or APN is acceptable when the property type is Land / Agriculture, or the construction status of the property is Under Construction / Proposed. These fields are not for the listing of additional information about the property (see Property Description section below). Entering "Confidential", "Call Broker", "Withheld", or any other verbiage designed to withhold, hide, and/or conceal the physical address in the Address1 or City Name fields is strictly prohibited. We reserve the right to remove any and all property listings with non-address related or invalid information in any address specific field with or without contacting the listing broker.

Property Description

Property descriptions are for the description of the property that is for sale or for lease only. The posting of contact name, phone number, fax number, company information or URL links for any contacts including those who are not our customers is strictly prohibited in this section. This type of information in the Property Description field will be removed from the listing and the listing broker will receive an email informing them of the change. Habitual violations of this policy will result in our removal of all of such your active listings on the Site at least until all such content has been appropriately cured.

Property Type

Properties must be identified with the appropriate property type. You have the option to select up to three (3) ‘Also Market As’ property types.  We reserve the right to change or remove property types deemed to be misleading.


A valid Sales Price in the Price Asking field for the listed property is required for all Site Sale Listings and a valid rental rate for each space is required for all Site Lease Listings. We reserve the right to remove all listings that are deemed to have invalid prices or rental rates including any listing with $0 listed in Lease Rate, Sales Price and Opinion of Value fields.

Listing Parameters

In order to maximize the features of the Site, you should note certain parameters in the listing process:

Commercial Property

The Site is a web site for commercial real estate. Listing of single-family residences is prohibited on the Site, except if such residences have a residential income purpose (e.g. to purchase a residence whose customary use has been as a rental property), in which case such properties may by listed under the Residential Income category only. The listing of single family residential income property under all other categories is prohibited. Any listing deemed to be a non-income generating, single-family residence will be removed from the system during the listing approval process and we will send you an email stating that the property has been identified as a single-family residential property.

Contact Information

Premium Subscriber Listings added to the Site will receive Premium Lister benefits if the Primary Contact referenced for that listing is a Premium Lister within his or her Premium Listing Plan.


-          Property Listings  We prohibit the listing of a single property more than once on the Site at the same time. A duplicate is defined as the same space and property availability listed under more than one Listing ID. We reserve the right to remove any and all listings that are determined to be duplicates with or without contacting the listing broker. You may, however, list a property for sale and for lease at the same time.

-          Business For Sale Listings  We prohibit Business For Sale listings if there is no commercial real estate for sale. Business For Sale listings with commercial real estate for sale are permitted and must adhere to the Listing Policy.

-          Space Listings  We prohibit the listing of the same space more than once on the Site at the same time. A space listing is defined as a single suite or unit of space listed for lease. We provide minimum divisible/maximum contiguous options for divisible space. Total space available in a building cannot exceed the total square footage of the building and total space available per floor cannot exceed the typical floor size. We reserve the right to combine duplicate space listings into a single listing or to remove the listing from the system with or without contacting the listing broker.

Listing Quantity, Submission, and Display

You may list an unlimited number of listings on the Site. Premium Lister subscription provides Premium exposure for the number of listings paid for in the Premium Listing Plan. Premium Listers must list all Premium listings in accordance with the Site Terms. Standard Listings submitted to us will be available on CoStar.com and will not be fully displayed on LoopNet.com search results for searchers to view.

Use of Photographs, Videos and Document Attachments

Building photographs, videos and document attachments posted, attached, or affixed to listings must be actual photographs/videos/documents of the building being listed. All such photographs, videos and document attachments must be either (a) the property of the listing broker or (b) the listing broker must have received all necessary rights and authorizations, including from the photographer/videographer and/or copyright owner of any photographs/videos, to publish such photographs/videos on your website or on the Site for the purpose of advertising the subject property. Photographs, videos and document attachments uploaded that are not directly related to the building or property being listed, including brokerage company logos, may be removed at our discretion.

Prohibited Conduct

You are advised to refrain from engaging in the conduct specified in this section, as it is not permitted on the Site:

"Billboard" Listings

Listings on the Site are for properties that are currently offered for Sale or Lease. It is not permitted to post listings on the Site that have already been sold or are no longer on the market, i.e. posting listings on the Site for marketing or advertising purposes ("Billboard Listings"). All listings for properties already sold or off-market will be removed.

Keyword Manipulation

We offers the ability to search for properties on key words. This is designed to enable searchers to narrow their criteria based on specific requirements. Keyword manipulation is unfair to searchers by returning listings that clearly do not meet their criteria. Keywords identified in the property name, property description, location description or property highlights field that are clearly not relevant to the property being marketed will be removed by Listing Review. Your habitual abuse of this policy may, at our sole discretion, lead to the removal of all of your active listings from the Site and suspension of your ability to list properties on the Site.

Offensive Language

Use of profanity or vulgar language in any part of the Site is strictly prohibited. This includes the use of language that is generally considered obscene, profane, sexual, hateful, or racist in nature. Listing or user information that includes profane language will be removed from the Site immediately. You posting such language to the Site may be subject to disciplinary action, including indefinite suspension of your account, temporary suspension or a formal warning.
