Tips to Stay Legal
- Check whether your address falls under county or city code by consulting zoning maps.
- Contact local planning, zoning, or animal control to verify chicken rules before building a coop.
- Avoid roosters unless your zoning clearly permits them.
- Respect coop setback requirements and enclosure size standards.
- Register your flock with the Maryland Department of Agriculture.
- If you need a permit or license, do not begin keeping birds until it’s approved.
- Watch for smell or noise complaints—they can trigger enforcement even if keeping is legal.
Why These Rules Matter
These rules help keep neighborhoods peaceful by reducing noise, odors, pests, and health risks. Setbacks keep coops clear of neighboring yards. Permits and coop standards ensure proper animal care. Registering flocks helps prevent disease outbreaks. Together, these rules balance personal convenience with community wellbeing.
Final Takeaway
Maryland generally allows backyard hens—but exact limits depend on your county and whether you live in a city or rural area. Most counties permit around 4–8 hens on modest lots, ban roosters, and enforce coop setbacks and hygiene standards. Larger lots or agricultural zones often allow more freedom.
