If you’re planning on building out a rooftop or updating your landscaping in the city of Chicago, then these are the top 4 codes you should know.
But to put this into perspective, I suggest we think about codes as something to embrace rather than be amazingly annoyed by them.
This is not an out-of-the-box thinking kind of conversation. This is about codes. We all live with codes. We all agree in the US to drive in the right lane, stop at red lights, walk through an intersection at appropriate signals (most of the time), park in designated spots, etc. You get the point, right?
We use codes because we need to have ways to operate with each other; we need best practices to keep ourselves and others safe.
Just like homebuilders have codes to follow, so do we in landscape design/construction. And these codes are set by the city / municipality in which you dwell.
For Chicago city dwellers (i.e., residential properties), there are 4 key codes that are worth knowing about when you’re planning for landscape construction.
Since 2016 . . .
ONE: Rooftop Structures
On a private residential roof deck any structure above the parapet wall that is within 3’ feet of a property line or 6’ off a neighboring building has to be noncombustible. If this applies to you, then your pergola needs to be made of a metal and any screening needs to be made of metal, glass, or cement board.
TWO: Backflow Preventer
Irrigation systems require a backflow preventer installed by a licensed plumber and they need to be inspected yearly. The inspection is typically done by your irrigation company which has proper certification.
THREE: Fence Height
Anything less than 5 feet tall does not require a permit when built with typical materials (e.g., wood, vinyl, steel). But fencing can be up to 6 feet for solid panels and up to 8 feet for open slats. These heights may require a permit and a variance request. The takeaway is to follow neighborhood fencing heights, always talk to your neighbors, and hire professionals who know the codes!
FOUR: Parkway Trees
All trees in parkways are city property (no matter who plants them). Technically you’re supposed to get a permit to do any work in/on parkways, but functionally the city is fine with homeowners making improvements. However, existing trees cannot be removed! THIS IS HUGE! The fine is $1,000 per caliper inch. This means if you remove a 20” diameter tree you will be fined $20,000!
In order to plant a tree in a parkway, you must hire a company that is licensed by the city of Chicago to plant parkway trees, and you are going to be limited to 4 – 5 options. The city determines which options you have by what other trees are planted in your neighborhood. The city’s goal is to diversify plantings.
Major take away: When you’re contracting with a company (like Topiarius) to work on / at your home make sure you find and use a reputable firm that has up to date knowledge of codes. And don’t ever be discouraged by these codes . . . design solutions abound so that you can live beautifully outdoors.
