This is the single most important thing a Hartford buyer should understand before anybody quotes them for dog-based work.
Hartford Code section 6-2 requires a dog to be on a leash whenever it is off the property of its owner, with a published penalty of fifty dollars. Not off town park land specifically. Off the owner's property, full stop. No working-dog or commercial-dog exemption appears in the section's text, and the city's own resident guidance repeats that dogs must be leashed at all times, including in city parks.
The parks chapter adds a second provision that matters for one of the city's largest open landscapes: a person may not walk or allow a dog to roam in a municipal cemetery.
We are telling you this because it directly constrains a method that depends on controlled working movement, and because the public text does not establish that a contract, a permit or a departmental approval automatically creates an exception. Anybody who tells you their commercial purpose overrides section 6-2 is telling you something the code does not say.
What that means in practice is that a Hartford deployment needs written site authorization plus a clear, legally confirmed account of how section 6-2 is satisfied, agreed before the first visit rather than after a complaint. On a municipal cemetery the separate cemetery provision has to be resolved as well. On private ground, a course, a campus, a cemetery in private hands, an association, the owner's authorization plus the leash rule's application to that property is the question, and it is usually a much shorter conversation.
We would rather lose a job at the quoting stage than start one that gets stopped in week two.
