Contractor License & Permit Bonds in Maryland

Maryland bonds contractors at the state, county, and city level

Maryland runs a real state home-improvement program through the Maryland Home Improvement Commission (MHIC), but its bond is an option rather than a universal mandate — see below. The bonds Maryland requires outright are the state well trades, a layer of county and Baltimore City trade bonds, and the state highway and county right-of-way work. We cover Maryland’s verified depth: the master well driller and water pump and conditioner installer state bonds, the county and city contractor bonds, the State Highway Administration performance bond, and a statewide contractor license general-use product for the long tail of county and municipal obligees.

The MHIC bond is an option, not a universal requirement

Every Maryland home improvement contractor is covered by the Home Improvement Guaranty Fund, which is funded by license fees. The MHIC contractor bond itself is a financial-solvency alternative: an applicant who demonstrates sufficient net worth to the Commission satisfies the requirement without a bond, and only an applicant who cannot must post a two-year surety bond instead (COMAR 09.08.01.19). Because the bond is avoidable by the net-worth showing, we list the program rather than state a fixed price — the exact amount is confirmed when you start your bond. Maryland eliminated its separate home-improvement subcontractor license in 2016, so this is a single contractor program.

Maryland’s mandatory state bonds are the well trades

The Maryland Board of Well Drillers (Department of the Environment) requires a surety bond before licensure, with no letter-of-credit or cash substitute (COMAR 26.05.02.05). A master well driller posts a $5,000 bond; a water pump installer or water conditioner installer posts $2,000 — both fixed, both mandatory, and a licensee may not practice while unbonded.

County and Baltimore City trade bonds carry the verified depth

Maryland’s counties and cities license the trades, and several set fixed, codified bond amounts. The City of Hagerstown requires a $20,000 bond of building contractors and carpenters; Baltimore City requires a $10,000 bond as a condition of a demolition or exterior-removal permit (Building Code § 105.3.3) and a $2,500 master electrician bond (City Code Art. 13). The City of Frederick requires $5,000 of utility/irrigation contractors, and Frederick County $10,000 of electrical contractors.

On the sanitary side, Calvert County requires a $10,000 bond of on-site sewage disposal installers and Dorchester County a $2,000 bond of its sanitary construction and liquid-waste-hauler licensees. Washington County requires a $3,000 bond for constructing a commercial or logging entrance on a county road.

Right-of-way, grading, and the long tail

For work in the public right-of-way and on graded land, Maryland’s jurisdictions post permit security whose amount is set per project — a performance bond, letter of credit, or cash. These include the State Highway Administration entrance/access permit bond, Montgomery County right-of-way permits, and the Anne Arundel and Howard County grading bonds. Because the amount is set per permit or by a formula, these are listed without a fixed price; where a Maryland jurisdiction requires a contractor license bond we do not individually carry, the statewide contractor license general-use bond covers it.
