Landscaping insurance cost in Colorado: what the underwriter is looking at

The honest answer is that an underwriter reading a landscaping application is not pricing “landscaping.” They’re pricing five or six specific things you do, and most of them aren’t mowing. Payroll and how it splits by task. Whether you spray. Whether you build walls. What you tow and how far. Whether the same crew plows in January. We insure landscaping contractors across Colorado and run a Yanmar mini skid steer on our own install work, and we don’t publish a price on purpose. What follows is the application, read in the order the underwriter reads it, so you know which input is doing the work on your bill.

The one thing we’ll cite, and what it is worth

We looked for a premium range from a source we could stand behind. Most of what’s online is agency marketing pages and lead-generation sites with a made-up multiplier, and we’re not repeating those.

What we did find is a rate outlook from the trade side. The National Association of Landscape Professionals’ blog, in February 2025, reported a broker’s estimate that commercial auto would rise ten to fifteen percent that year, general liability and umbrella six to eight percent, with workers’ comp mostly stable, and named large equipment fleets and bodily injury severity as the reasons. That’s a national direction, not a Colorado number, and it’s already a year and a half old as we write this. It tells you which way the wind blows. It doesn’t tell you what your policy costs.

The seven inputs, in the order the underwriter reads them

1. Payroll and the class code split

Payroll is the base for workers’ comp and, on most contractor GL forms, for general liability too. The class code is the multiplier, and landscaping has more than one.

The split is the lever. A crew that installs sod and plants in April and mows the same HOA from May to October commonly rates under two different codes, and the maintenance code sits lower. Put everyone under the install code because it’s simpler and you pay the higher rate on the mowing hours all season. Timecards by task are what let the audit split it.

And there’s no threshold below which comp is optional. Colorado employers must carry workers' compensation insurance as soon as they have one or more employees, whether part-time, full-time, or family members (C.R.S. 8-40-203(1)(b), 8-44-101); the state can fine an uninsured employer up to $500 for every day without coverage. (C.R.S. 8-40-203(1)(b); 8-44-101; 8-43-409) The seasonal crew you bring on in May counts from the first day.

2. Whether you spray

The chemical program changes the shape of the policy more than the base rate. Under most standard GL forms, herbicide and fertilizer drift is a pollution claim and excluded. The applicator statute’s liability minimum is satisfied by a policy with that exclusion in it ( C.R.S. 35-10-106(1)(a); 8 CCR 1203-2), so holding the license doesn’t buy drift coverage. The fix is a pollution endorsement or standalone policy, and that is a real line on the bill. The herbicide overspray article covers the whole gap. For the premium, the question is whether chemical revenue is a side item or a program across a dozen HOAs.

3. Hardscape, walls, and completed operations

Mowing claims happen the day of. Wall claims happen three winters later. A retaining wall built on expansive clay in Castle Rock that heaves and leans is a completed-operations claim, and the underwriter prices it when they see “retaining walls” on the application. Pavers over a base that wasn’t compacted with the plate, a drainage grade that sends water at the foundation, a boulder wall on a slope in Evergreen: all completed ops. The hardscape and paver page covers the exposure. On the bill, a design-build outfit rates above a maintenance crew for this reason alone.

4. Trucks, trailers, and the mini skid steer

Commercial auto on a landscaping outfit rates on the trucks, the trailers behind them, the drivers, and the radius. A one-ton pulling a 16-foot enclosed trailer of mowers from Aurora to Parker every day is the auto risk the NALP outlook was talking about. Crew members driving their own pickups to the job is the hired and non-owned question, and it’s rated too.

The equipment is its own line. The mini skid steer, the mowers, the plate compactor, the sod cutter: scheduled on the equipment floater at values you’d actually pay to replace them. Trailer theft out of a yard in Weld County is the claim we see most on this line, and hail on the Front Range every summer is the second.

5. The contracts you sign

HOA and property management contracts commonly ask for $1M/$2M general liability with the association and the manager as additional insured, primary and non-contributory, and a waiver of subrogation on the comp. Municipal and school district mowing bids add higher limits and sometimes pollution coverage. Every ask is a line on the bill. Buy to the contract you sign next, not the one you signed last year.

6. Whether you plow

Snow changes the read. Slip-and-fall is a bodily injury exposure, and a landscaping GL that carries a plow route rates for it, or excludes it, or never heard about it, and the third one is the one that hurts. The snow plowing cost article walks the snow drivers on their own, and the summer-and-winter gap article covers what breaks when one policy is asked to do both seasons.

7. Loss runs

Carriers typically read three to five years of claims history, and they read the story. A rock through a window from a mower with the guard on is one thing. A wall that failed with no compaction record is another, and it follows you to every renewal in that window.

What moves the number, and what you control

Colorado specifics that show up on the bill

Expansive clay. Across the Front Range, especially Douglas County, the soil moves. Walls, patios, and drainage grades built on it are completed-ops claims waiting on a wet spring. Underwriters know it, and it shows in the GL rate for hardscape work.

Wind on the plains. East of I-25, around Greeley and Weld County, a normal Tuesday application becomes a drift claim when the wind comes up at 10 a.m. The chemical program rates differently out there, and it should.

Hail. May through September. A yard full of mowers and a trailer of plant material takes it every year, and where the equipment sleeps matters to the inland marine underwriter.

Elevation. Above 8,000 feet the install season is short and the freeze-thaw is hard on everything you built. Short seasons mean concentrated payroll and a winter with either snow revenue or none.

How to get a real number

Send what the underwriter needs and you get a quote instead of a guess. Payroll by class with a note on who does install and who mows. Whether you spray, and how much of the revenue it is. What you build: walls, patios, drainage, with the tallest wall you’ve done. Every truck and trailer, the radius, and who drives. The equipment list with what you’d pay to replace each piece. Your worst HOA contract’s insurance section. Whether you plow. Five years of loss runs.

Already carry coverage? The fastest move is the policy review. Send the dec pages and we’ll mark which of the seven inputs is doing the most work on your premium, and whether the pollution exclusion and the snow question are handled or ignored. Starting fresh? Get Insured lists what to have ready, and the licensing article tells you which cities will ask for a certificate before you can pull a permit. No online quote, on purpose.

The only accurate number is a quote built on your operation.
