Saint John Long Grass Rules Explained: What the By-laws Say (and Don't)

Saint John has no grass height limit in its Unsightly Premises By-law, M-30. That by-law targets junk, rubbish, construction waste, wrecked vehicles and run-down buildings. It doesn't name a number for grass. But a messy yard can still draw a complaint. The City's Community Standards program can send a Notice to Comply, then clean up and bill the owner if nothing changes.

Does Saint John have a long grass bylaw?

Not one with a height in it, as far as we can find. Many Canadian cities set a hard limit, like 15 or 20 cm. Saint John's main yard rule works a different way.

The rule is section 6(1) of the Unsightly Premises and Dangerous Buildings and Structures By-law, M-30. It says you can't let your property look unsightly by leaving these on it:

• ashes, junk, rubbish or refuse
• a pile of wood shavings, paper, sawdust or other building waste
• a derelict vehicle, equipment or machinery
• a dilapidated building

Grass isn't on that list. Neither are weeds. So you won't find a "10 cm" or "20 cm" line for Saint John, the way you will in some cities.

The City's own report page says the same thing in plain words. It says an unsightly property can include derelict vehicles, junk, garbage and scraps from building or tearing down.

So can you let your grass grow as long as you like?

Not quite. "No number" doesn't mean "no rules." Three things still matter.

1. Junk hiding in long grass still counts

A tall, shaggy yard often hides other stuff. Old tires, broken lawn chairs, scrap wood and bags of trash all fit the M-30 list. Long grass around them makes them easy to spot from the street. That's the kind of yard that gets reported.

2. The City looks at "general upkeep"

Saint John runs a Community Standards program. The City says it focuses on the look, enjoyment and pride of a neighbourhood. That includes unsightly premises, zoning issues and the general upkeep of properties.

3. A provincial yard code covers noxious plants

The City's by-law compliance page links to New Brunswick's Residential Properties Maintenance and Occupancy Code. Section 4 of that code says a yard must be kept reasonably clean and free of rubbish. It must also be kept free of ragweed, poison ivy, poison sumac and other noxious plants. We couldn't open the City's own Minimum Property Standards By-law to see how it uses that code. So check with the City if a notice ever names it.

What happens if someone reports your yard?

The City says its first step is education. Staff look into complaints and inspect the property. They try to work it out with you before anything else.

1. A friendly push. Staff work with the owner to get a voluntary cleanup.
2. A Notice to Comply. If that doesn't work, the owner gets a notice. It gives a set amount of time to fix the problem.
3. The City cleans it up. If the deadline passes, the City can remove the problem itself. It then sends the bill to the owner.

The City says it turns to penalties and fines only if education and teamwork fail. We didn't find a fine amount on an open City page, so we won't guess one.

How do you report an untidy yard in Saint John?

Use the Unsightly Property form on the City's website, under "Report a By-Law Infraction." The City says it doesn't accept anonymous complaints. You'll need to give your name and contact details, plus the address of the problem.

For questions about the property programs, the City lists Growth and Community Services at 506-658-4455. Noise is different. For a noise complaint, the City sends you to the Saint John Police non-emergency line, 506-648-3333.

Before you file anything, try a quick chat. Your neighbour may be away, hurt or between mowers. A friendly word often works faster than a form.

How does Saint John compare with Moncton and Fredericton?

City	Grass height rule
Saint John	None in By-law M-30. Junk, rubbish and run-down buildings are the focus.
Moncton	Tall Grasses By-law Z-1418: 20 cm (about 8 inches), including the street strip in front.
Fredericton	None. The City says its unsightly premises by-law has no grass height for private property.

So if you own homes in more than one New Brunswick city, the rules aren't the same. A lawn that's fine in Saint John could break Moncton's rule. Our guide to long grass bylaws in Canada covers more cities.

Why does Saint John grass grow so fast?

The weather here keeps it going. At the Saint John airport station, the average July day is 17.1 °C. That's cooler than Fredericton (19.3 °C) or Moncton (18.8 °C). Saint John is also wetter, with about 1,295 mm of rain and snow a year.

Cool, damp weather suits lawn grass. It tends to keep growing through the summer instead of going brown and slow. The average last spring frost is May 16. The first fall frost averages October 2. Treat those dates as a rough guide.

That means a long mowing season. If you skip two weeks in June, the lawn can get away from you fast.

How do you keep a Saint John lawn neat without a height rule?

Even with no number to hit, a regular cut keeps the yard tidy and the neighbours happy. Here's what works:

• Mow on a set day. Weekly suits most Saint John yards from late May into October.
• Follow the one third rule. Iowa State University's extension service says never cut more than one third of the leaf at once. If the grass gets long, bring it down over two or three cuts.
• Wait for dry grass. The same source says wet grass is harder to cut, can clog a mower and is more slippery. That matters on the hills of Saint John West and Island View.
• Trim the edges. Fence lines, posts and the curb strip look shaggy first. Good trimming and edging fixes that.
• Drop the height late in fall. Ohio State University Extension says to mow at 5 to 6.5 cm (2 to 2.5 inches) as winter comes. Lower the blade about 1.3 cm (half an inch) each time.
• Pick up the junk. Old toys, scrap and bags in the yard are what M-30 is really about.

Our partner crews don't spray, and Golden Oak gives no advice on weed killers or other chemicals.

Where do the clippings go in Saint John?

• Green compost cart: grass clippings, leaves, cedar clippings, weeds and twigs up to 2 inches (about 5 cm) across.
• Extra yard waste: brown paper leaf bags only. No plastic bags.
• Weight limit: a full cart can't weigh more than 100 pounds (about 45 kg).
• Placement: set the cart at the edge of the driveway, wheels toward the house, lid closed.
• Timing: for daytime pickup, put it out between 10 p.m. the night before and 7:30 a.m. Use the City's ReCollect tool for your schedule.

Grass that's been sprayed with chemicals doesn't go in the compost. Got too much for the cart? Crane Mountain Landfill takes one cart (two brown paper bags) of compost for free. A bit more costs a small fee. From Saint John, take Highway 7 North toward Grand Bay-Westfield. It's open weekdays 7:30 a.m. to 5 p.m. and Saturdays 8 a.m. to noon.
