Only select trades are required to be licensed in Washington. The DCRA handles licensing for the general contractors and home improvement contractors only.

Advantages of Having a License

The District of Columbia, including Washington D.C., has established various rules and regulations involving the construction industry to promote the health and safety of its residents. This is why they require certain trade workers and contractors to be licensed.

The District has what it calls its “disgorgement rule”. If you are an unlicensed contractor but you worked on a project anywhere in the District of Columbia, you are legally required to return all the payment the client has given you even if he or she was satisfied with your work.

Being licensed also gives you the right to charge higher, since you have sufficient proof that you are fully qualified to do the job. Licensed contractors and workers are much more in demand now than unlicensed ones, especially for costly projects, because clients know that they will be getting their money’s worth once they hire one, that’s why they proactively search for them.

The Importance of Hiring a Contractor With a License

Everyone knows that construction projects are generally costly, so people would try their best to cut costs and save as much as they can. Unfortunately, these cost-cutting measures sometimes result in the total opposite of what they are expecting and going over their initial budget.

One of the common examples for this is when you hire an unlicensed contractor. You may think that you will be saving money by doing so, since they charge lower than licensed contractors, but this is a very risky move since this generally ends up costing you more. Many homeowners have complained about unlicensed contractors not finishing the work, suddenly disappearing in the middle of the project, producing unsatisfactory results, and many others. By hiring licensed contractors, you eliminate, or at least lessen, these issues.

While Washington D.C. allows you to get your money back whenever you hire an unlicensed contractor, the stress and headaches are not worth the risk. In contrast, licensed contractors will give you a peace of mind.

Washington, D.C. Contractor License Search

You can check if the contractor has the required Basic Business License in Washington D.C. using the online database found at https://eservices.dcra.dc.gov/BBLV/Default.aspx. This applies to general and home improvement contractors, since they are required to have the BBL before accepting contracts.

For the other trades, you can search the licenses at https://trades.dcopla.com/Public/MemberSearch/BITLicense.

Contractor’s License Reciprocity

Having issued a license in any city, county, or state with a contractor’s license reciprocity agreement with another has a major perk. That is, it allows you to bypass some of the requirements in order to get the same or equivalent license in the reciprocal city, county, or state.

If you have been issued a contractor’s license, or any construction trade license for the matter, you know how time-consuming and costly it is to obtain one. License reciprocity agreements will save you time, effort, and money, since these agreements generally allow you to submit only a fraction of the usual requirements in order to obtain the license in another state, city, or county, as well as skip the required examinations.

Unfortunately, Washington D.C. does not have a license reciprocity agreement with any city, county, or state.
