Yes, full-time RV living in Maryland is legal but tightly constrained by local zoning, health codes, and vehicle regulations. The state lacks a uniform statute, forcing residents to navigate county-specific ordinances that often prohibit permanent RV residency in residential zones. Maryland’s Department of Housing and Community Development (DHCD) enforces the 2026 Statewide Housing Policy Framework, which discourages long-term RV occupancy in unpermitted areas, though rural counties may permit it with conditional use permits. Vehicle registration under the “Recreational Vehicle” classification requires compliance with Maryland Motor Vehicle Administration (MVA) standards, including annual inspections and proof of domicile for insurance.
Key Regulations for Living in an RV Full Time in Maryland
- Zoning Restrictions: Most counties, including Montgomery and Prince George’s, prohibit RV residency in residential zones unless the vehicle is parked on a property with an approved accessory dwelling unit (ADU) or agricultural exemption. Baltimore County’s 2025 zoning update explicitly bans “habitable RV occupancy” beyond 30 consecutive days in non-RV parks.
- Health and Safety Codes: The Maryland Department of the Environment (MDE) mandates RV parks comply with sanitation standards under COMAR 26.11.02, but counties like Anne Arundel enforce additional septic and potable water requirements for off-grid setups. Violations can trigger fines up to $1,000 per day.
- Vehicle Compliance: RVs must meet MVA’s “park model” or “travel trailer” classification, with annual inspections verifying brake systems, emissions (for diesel models), and structural integrity. Domicile proof (e.g., utility bills, voter registration) is required for insurance under COMAR 11.22.03.
