Read this before you act on anything below. This is my researched starting point for Allegany County, MD, not legal advice and not a guarantee. Rules change, and the deciding facts on any specific parcel (setbacks, perc results, overlay districts, deed restrictions, road frontage) live at the county or town office, not in any database. Before you buy land or build, confirm the current rules directly with the local zoning and health offices - the sources on this page tell you exactly who to call.

The local rulesAllegany County, MD

Zoning & raw-land occupancy
Varies locallyAllegany County has a countywide zoning ordinance adopted by the County Commissioners in 2017, covering unincorporated areas and the LaVale Zoning District; the code presumes broad land-use permissibility but actual buildability depends on your specific zoning district. Towns within the county have their own separate zoning. source
Dwellings, tiny homes & RVs
Varies locallyStandard, modular, and mobile homes are recognized dwelling types with county permit checklists, and manufactured homes must meet Maryland state certification. Rules for tiny-homes-on-wheels as permanent residences are not confirmed on any official county page.
Building permits & codes
RestrictedThe county requires a Land-Use Permit and, for most new construction, a full Building Permit process including plan review, inspections, and a Certificate of Occupancy, administered by the Office of Building Safety & Construction under the county's adopted building code. source
Septic & composting toilets
RestrictedOn-site septic systems require a Health Department permit and a percolation test to confirm soil suitability, issued by the Allegany County Health Department's Environmental Health Division. Composting toilets are not separately addressed on an official county page. source
Greywater reuse
Unclear - verifyNo county-specific greywater ordinance was found; this appears to default to Maryland's statewide framework. Not confirmed locally, so check with the Health Department if you plan a greywater system.
Rainwater harvesting
Unclear - verifyNo Allegany County-specific rainwater harvesting rule was found; this likely defaults to Maryland Department of the Environment's statewide recognition. Not confirmed at the county level.
Private wells & water rights
Generally allowedPrivate wells are permitted through the Allegany County Health Department, which processes well permit applications, requires a licensed driller, and mandates a potability water test after drilling. source
Living disconnected from utilities
Unclear - verifyFull disconnection from utilities isn't addressed as its own legal category by the county; instead, ordinary building, septic, and well permitting requirements act as the practical gatekeepers for any self-sufficient home.
