Maryland Contractor License Guide

In Maryland, general contractors do not need a license to perform work in the state. A license is only required if you wish to work on home improvement projects or do electrical, plumbing or HVACR work. The licensing process is handled by the Department of Labor, Licensing and Regulation (DLLR).

  • Home Improvement License - Contractors performing any work that involves repair, replacement, remodeling or alteration of any part of a residential building are required to have a Maryland Home Improvement License.
  • Master Electrician License - To perform electrical work you are required to obtain a master electrician license.
  • Plumber’s License - If you wish to do plumbing work you must get a master or journey plumbing license.
  • HVACR License - To perform HVACR work you must obtain either a master (restricted), limited contractor or a journeyman license.

  • Provide proof of net worth
  • To obtain your Home Improvement License you are required to provide a financial statement with your application. Note that the net worth (assets - liabilities) must be at least $20,000.

    Note: If you are not able to provide a positive net worth, you may obtain a two year $20,000 surety bond instead.

  • Provide real estate and bank statements
  • If real estate is listed on your financial statement you must provide a copy of your current property assessment notice(s). You are also required to enclose copies of the last three months of personal bank statements. Note that business accounts are not taken into consideration.

    Note: Your application should have a notarized signature of co-owner(s) of real estate, bank accounts or other assets (if any).

  • Provide a credit report
  • Along with your application you will need to submit a current, original credit report (no older than 90 days). You can obtain a credit report via Annual Credit Report.

  • Submit certificate of liability insurance
  • Proof of general liability insurance of $50,000 or more must be submitted. The certificate must include the name of the applicant and the company’s name and the Maryland Home Improvement Commission should be designated as the certificate holder.

  • Submit a copy of conviction records
  • You are required to provide a copy of all conviction records regarding felonies (and any misdemeanor convictions relating to a home improvement transaction) along with a letter of explanation of each conviction plus proof of completion of parole/probation.


Pass Examination

To obtain your Home Improvement License, you must pass a contractors’ exam covering laws and regulations. The examination services are handled by PSI and the exam is given daily from Monday through Friday. Testing centers are located in Baltimore, College Park, Salisbury, Frederick, Hagerstown, Lanham and Crofton. Test dates are by appointment only and confirmed in writing.

To take the exam you must make an appointment with PSI by contacting them at 1-800-367-1565, by email at [email protected] or via their website. A confirmation of the exam date and time will be sent in writing.

Note: After receiving a passing score on the exam you have two years to apply for a license before the test score expires.


Obtain Your Contractor License Bond

In the state of Maryland all Home Improvement License applicants must provide a positive net worth statement with their contractor license bond application.

A two year surety bond in the amount of $20,000 can be filled in place of the financial statement in the event you do not meet the required net worth. The bond must show the person and business name, and be signed by the applicant. The surety bond forms can be accessed here.

There may also be local requirements for contractor licensing and bonding. Please contact the city or county where you anticipate working for complete information.
