Tiny home rules in Baltimore, MD — covering tiny houses on wheels (THOWs), park model RVs, and tiny home on foundation builds — determine where they are legal and how they get permitted.
Tiny homes built on a foundation in Maryland must comply with the Maryland Building Performance Standards, which adopt the IRC including provisions governing dwellings four hundred square feet or less.
Under Public Safety Article Section 12-503, the Maryland Building Performance Standards require every jurisdiction to enforce the International Residential Code. The IRC defines a tiny house as a dwelling four hundred square feet or less in floor area, excluding lofts, and Appendix Q provides reduced ceiling heights, ladder access, and emergency egress allowances when adopted. Park-model RVs and tiny houses on wheels are typically regulated as recreational vehicles under federal NFPA or ANSI standards rather than the IRC. Local jurisdictions may adopt Appendix Q or impose stricter zoning and minimum dwelling size rules but cannot drop below MBPS thresholds.
Occupying or constructing a tiny dwelling that fails to meet IRC requirements can result in code enforcement actions, denial of occupancy, condemnation, and removal orders.
