Off-Grid Living in Anne Arundel County, Maryland

Anne Arundel County runs its own countywide zoning and permitting system that's noticeably stricter than many rural counties, with no clear path to living full-time in an unfixed tiny house or RV on raw land. Septic and well rules come from the county Health Department layered on top of Maryland's state standards, while greywater and rainwater largely fall back to state rules since no county-specific ordinance was found.</summary> <parameter name="framework">{"zoning":{"status":"varies","note":"Anne Arundel County (outside Annapolis) administers its own countywide zoning code through the Office of Planning and Zoning, with districts like R5 setting lot size, coverage, and height limits.

Anne Arundel County at a glance

Zoning & raw-land occupancy
RestrictedAnne Arundel County (outside Annapolis) runs its own countywide zoning code through the Office of Planning and Zoning, with districts like R5 setting minimum lot size, coverage, and height limits. Annapolis has a separate city planning and zoning authority, so which government you deal with depends on exactly where the land sits.
Dwellings, tiny homes & RVs
RestrictedThe county's zoning code has no definition for a tiny house on wheels, so a THOW isn't recognized as a permanent dwelling on private land and can generally only be lived in full-time in an RV park, campground, or licensed mobile home park. A tiny house on a permanent foundation can potentially qualify as a dwelling or ADU under Maryland's new statewide ADU law, and the County Council (Bill 48-25) is moving toward allowing purpose-built tiny home communities, but living in an RV or THOW on your own raw land isn't confirmed as legal. source
Building permits & codes
RestrictedThe Department of Inspections and Permits requires standard permits and inspections for dwellings, additions, and most structures, now largely processed through its online Land Use Navigator system. Only small accessory structures under a certain size are permit-exempt, and I didn't find any blanket off-grid exemption from the building code, so check directly with this department for your specific build. source
Septic & composting toilets
RestrictedAny onsite sewage system needs a Septic Installation Permit from the county Health Department, which enforces the local Anne Arundel County Private Sewage Disposal Code on top of state MDE standards, including site inspections for well and septic setbacks. I didn't find a specific county allowance for composting toilets as a septic alternative, so that would need to be confirmed with the Health Department's Bureau of Environmental Health. source
Greywater reuse
RestrictedI found no Anne Arundel County-specific greywater ordinance, so the county appears to follow Maryland's state law, which only allows reuse of shower, bathtub, and bathroom sink water. Whether the county Health Department has any additional guidance beyond that is not confirmed, so it's worth asking the Bureau of Environmental Health directly.
Rainwater harvesting
Generally allowedThere's no county ordinance found restricting rainwater harvesting, and the county appears to follow Maryland's approved environmental site design practices under state stormwater regulations. Whether there's a separate county plumbing-code provision for using harvested rainwater as potable water is not confirmed.
Private wells & water rights
RestrictedWells must be drilled by a licensed Master Well Driller under a permit from the Anne Arundel County Department of Health, with detailed local setback rules (for example, distances from foundations, property lines, and septic systems) and a required Certificate of Potability before the well can be used. In some areas like the Mayo Peninsula, the county can require wells to be drilled and sealed deeper than the state minimum to protect the aquifer, so local siting rules can be stricter than the state baseline. source
Living disconnected from utilities
Unclear - verifyI didn't find a standalone county ordinance banning full disconnection from electric, water, or sewer utilities. In practice, though, a legally permitted new dwelling can't get a Certificate of Occupancy until the Health Department has approved and certified its water source and sewage disposal method, so full off-grid living on a new build effectively still has to clear those approvals; ask the Department of Inspections and Permits and the Health Department about your specific situation.

If you're looking at Anne Arundel County for an off-grid setup, the first thing I want you to know is that this county is more regulated than a lot of rural counties I look at. Unlike some Maryland counties that leave zoning entirely to towns, Anne Arundel County has its own countywide zoning code administered by the Office of Planning and Zoning, and it enforces it. One big exception: the City of Annapolis has its own separate planning and zoning department, so if your parcel is inside city limits, everything here about "the county" doesn't apply to you.

On zoning, residential districts like R1 and R5 set lot size, coverage, and height limits, and I found lot minimums as small as 7,000 sq ft in R5. That's a county-level rule, not a state one.

Where it gets tricky is dwellings. As of recent county reporting, the zoning code has no definition for a "tiny house on wheels," which in practice means you can't count on living full-time in a THOW on your own raw land, only in a licensed RV park, campground, or mobile home park. A tiny house on a permanent foundation is a different story, it's treated as a dwelling or ADU under IRC Appendix Q and Maryland's new statewide ADU law. The County Council has also been moving on this, with legislation (Bill No. 48-25) setting up standards for purpose-built tiny home communities, but that's about sanctioned developments, not scattered individual off-grid placement.

Building permits are handled by the Department of Inspections and Permits, and I didn't find any off-grid or self-build exemption from the standard permitting and inspection process. Small accessory structures under a certain size may skip permits, but a primary dwelling won't.

Septic and wells are where the county Health Department (through its Bureau of Environmental Health) really takes the lead, layering local rules on top of Maryland's state COMAR standards. You'll need a septic installation permit, and the county's own Private Sewage Disposal Code sets standards that can exceed the state baseline. Wells need a licensed driller, a county-issued drilling permit, and a Certificate of Potability before you can legally use the water, with specific county setback distances from buildings, property lines, and septic systems. In sensitive areas like the Mayo Peninsula, the county can require wells drilled and sealed to a stricter minimum depth than the state baseline.

Greywater and rainwater harvesting don't appear to have county-specific rules, so I'd treat them as governed by Maryland's state framework, greywater reuse restricted mainly to shower/tub/sink water, and rainwater harvesting generally permitted. I didn't find a standalone county ordinance banning full grid disconnection, but occupancy permits are tied to having an approved water and sewage system in place, so full "off-grid" living on a newly permitted dwelling isn't straightforward.

Bottom line: confirm everything with the specific county office before you buy land or build.

FAQ

Common questions about off-grid living in Anne Arundel County

Is it legal to live off-grid in Anne Arundel County, Maryland?

There is no outright ban on living off-grid in Anne Arundel County, Maryland - it is legal but regulated. Zoning and land use are restricted, putting a cabin, tiny home, or RV on raw land is restricted, and building permits are restricted. Plan around septic/wastewater (restricted) and disconnecting from utilities (not clearly documented online, so confirm it locally). Because these rules are set locally, confirm the specifics with Anne Arundel County before you buy land or build.

Can I legally park a tiny house on wheels on my own land in Anne Arundel County and live in it full time?

Not confirmed as legal. The county's zoning code has no definition for tiny houses on wheels, so full-time occupancy on private raw land outside a licensed RV park, campground, or mobile home park isn't recognized. Check with the Office of Planning and Zoning for the current status.

Do I need a permit to drill a well or install a septic system?

Yes. Both require permits from the Anne Arundel County Department of Health, which also sets local setback rules and, in some areas like Mayo Peninsula, stricter well depth requirements than the state minimum.

Is rainwater harvesting allowed?

No county-specific restriction was found, so it appears to follow Maryland's state environmental site design rules, but this isn't confirmed with a dedicated county source.

What if my property is in Annapolis rather than unincorporated Anne Arundel County?

Annapolis has its own separate Department of Planning and Zoning, so none of the county-level rules described here would apply; contact the city directly.
