Your Maryland Home Improvement License renews every two years through the Office of the Attorney General Consumer Protection Division. Renewal deadlines are based on your license issue date—typically 24 months from issuance. You must renew before the expiration date or you cannot legally operate (Maryland Commercial Law § 13-304). Renewal costs approximately $300–$400 and requires proof of current general liability insurance ($300,000 minimum coverage) and an active $10,000 surety bond.

Maryland does not currently mandate continuing education for home improvement contractors, though staying current with building code changes is recommended. You can renew online through the Attorney General's portal using your license number and verification documents. If you miss the renewal deadline, you must reapply as a new applicant, retake the exam, and restart your licensing timeline. Late renewal penalties may apply if you continue operating with an expired license. Local building permits in Baltimore City require annual verification that your state license remains active, so maintain compliance to avoid permit denials on new projects.

Operating as a bathroom remodeler in Baltimore without a Maryland Home Improvement License is a violation of Maryland Commercial Law § 13-406, which imposes civil penalties of up to $5,000 per violation plus restitution to consumers. Criminal penalties include up to 18 months imprisonment and fines up to $10,000 for knowingly operating without a license or misrepresenting your credentials (Maryland Commercial Law § 13-407). The Office of the Attorney General actively investigates unlicensed contractor complaints and initiates cease-and-desist actions against violators.

Unlicensed bathroom remodelers may face immediate work stoppage orders from Baltimore City if discovered during permit inspections or homeowner complaints.

Customers can file complaints with the Attorney General's Consumer Protection Division, triggering investigations that often result in judgments against unlicensed contractors for breach of contract and fraud.

Operating without licensing voids your ability to file mechanic's liens against customer property, leaving you with no legal recourse for nonpayment. Your liability insurance will not cover work performed without proper licensure, exposing you to personal financial liability if injuries or property damage occur. The Attorney General maintains a public list of sanctioned unlicensed contractors, damaging your business reputation permanently. Previous violations make future licensing applications difficult, and courts may prohibit you from ever obtaining a Home Improvement License.
