Contractor Prequalification

Prequalification of General Contractors is required by the legislative act of the Baltimore County Council. Unless stipulated in a bid announcement, by addendum or in the contract documents, subcontractors are not required to be prequalified, but must be approved prior to the commencement of work.

Contractor's prequalification must be approved 10 days prior to Bid Opening. All questions and blanks must be completed on the application. Any omitted information may result in a delay in processing your application. New contractors should allow 60 days for processing. Please submit your completed application to:

Division of Construction Contracts Administration
111 West Chesapeake Avenue, Room 300 B
Towson, Maryland  21204

Contractors who are requesting additional categories be added to an existing prequalification should not fill out a new application. Please email your request to

The General Contractor is required to provide a bid bond for all projects and a performance and payment bond for 100 percent of the bid for all projects in excess of $25,000. Be advised that your application is subject to audit by the Baltimore County Office of the Auditor.

Three Reference Inquiry Forms are required for each work classification requested. Please note that a work classification is the Category (i.e. F—utilities) and Number (i.e. 1—sanitary sewers). Contractors are to only fill out the first page of the application. The reference inquiry forms are to be returned directly to us from the municipality for whom you have done work. Projects referenced shall have been completed within the last three years. Projects that were completed more than three years ago will not be considered. Work requested on the reference inquiry form must reflect work done with the company's own forces specific to the project referenced and can not include work that was subcontracted out.

Contractors requesting I-8 (Asbestos Removal) or I-9 (Lead Paint Abatement) must submit a letter stating that if for any reason their license is suspended or revoked they will notify Baltimore County in writing within 72 hours.

If you have any questions please send an email to or call 410-887-3531.
