Summary
Baltimore County's R.C.2 Agricultural Zone regulations protect working farms from nuisance complaints. Under BCZR Section 1A01.5, noise, odors, dust and machinery operation from a compliant farm cannot be treated as a public or private nuisance, even by neighbors who find it inconvenient.
Any dwelling, business or use in or near an R.C.2 Zone may be subject to inconveniences or discomforts arising from agricultural operations, including but not limited to noise, odors, fumes, dust, the operations of machinery of any kind during any 24-hour period (including aircraft), the storage and disposal of manure and the application, by spraying or otherwise, of chemical fertilizers, soil amendments, herbicides and pesticides. The County shall not consider an agricultural operation to be a public or private nuisance if the operation complies with these regulations and all federal, state or County health or environmental requirements; except that during the period between 10:00 p.m. and sunrise as defined by the National Weather Service for sunrise on the particular day in the Baltimore area, an agricultural operation may not fire or otherwise discharge an air cannon or similar device that releases a loud shotgun-like blast within 500 feet of an adjacent residential dwelling.

Full Breakdown
5 of the Baltimore County Zoning Regulations tells nearby residents and businesses to expect the ordinary side effects of farming. 2 Zone may be subject to noise, odors, fumes, dust, machinery operation at any hour, manure storage and disposal, and the spraying or application of chemical fertilizers, soil amendments, herbicides and pesticides. The County will not treat a farm operation as a public or private nuisance so long as it complies with the zoning regulations and with all applicable federal, state or County health and environmental requirements.
That protection is not unlimited: the same section carves out a specific nighttime restriction on one particular practice. and sunrise (sunrise defined by the National Weather Service for the Baltimore area on that day), a farm operation may not fire or otherwise discharge an air cannon or similar device that produces a loud shotgun-like blast within 500 feet of an adjacent residential dwelling. That carve-out, added by Bill No. 34-2009 and amended by Bill No. 62-2017, targets propane cannons used to scare birds off crops, balancing the broad nuisance shield against nighttime noise complaints from adjacent homes.
2 Agricultural Zone framework, which also sets a one-acre minimum lot size, a 75-foot setback from street centerlines and a 35-foot setback from other lot lines, and caps development at one principal dwelling per lot. 2 take on notice, by the terms of the zoning code itself, that agricultural activity next door is a protected, expected use rather than an actionable nuisance.
Violations & Fines
There is no fine schedule attached to Section 1A01.5 itself because it operates as a nuisance defense, not a penalty provision: it bars a nuisance claim or code-enforcement action against a compliant farm rather than punishing the farm. The only enforceable restriction is the nighttime air-cannon rule; a farm that fires a shotgun-like device within 500 feet of a residential dwelling between 10:00 p.m. and sunrise loses that specific protection and can be pursued through the County's standard zoning enforcement and nuisance-abatement process, including Zoning Commissioner action.
