Turf out, irrigation in, and a dig ticket before the trencher moves: going out on your own with a C-27

You already run the crew. You set grade, you pull the old turf, you solvent weld the mainline, you know which valve is leaking by the sound of it. What you have not done is sign the contract and take the call when the client says the new planting died. In California that is one decision rather than several, because the license and the business get built inside the same application: experience, two exams, a $25,000 bond, workers compensation and the entity choice all land together.

The C-27 Landscaping classification sits on top of a market that changed. California yards are being converted, not just installed. Turf comes out, irrigation goes to drip and smart control, planting goes to low water species, and the drainage has to actually work when the rain finally arrives all at once. That is retrofit work, it is repeat work, and it is the reason a C-27 today is a different business from a C-27 twenty years ago. Two rules decide whether you make money on it: the one about the acre, and the one about the phone call before you dig.

Call before you dig, every time, and on the small jobs too

Irrigation mainlines, drainage, lighting conduit, tree pits, footings for a garden wall: a C-27 crew puts steel in the ground almost every working day. California's rule is that you notify the regional notification center before excavating. It is not scaled to the size of the trench. The shallow trench for a lateral goes through the same gas service as a deep one.

The depth rules stack on top of it. Cave-in protection starts at 5 feet. A Cal/OSHA permit is required for trenches 5 feet or deeper. A trench needs a means of egress at 4 feet, within 25 feet of lateral travel. Landscape crews reach those depths on drainage runs and wall footings more often than the trade's reputation suggests, and the permit is a lead time item.

Build the ticket into the schedule rather than the morning of. The crew that plans mark out into the week before mobilization never loses a day waiting, and never has the far worse conversation about a struck service.

One acre is the number that changes your job

Stormwater permit coverage starts at one acre of disturbance. That is the threshold worth memorizing, because a landscape job that nobody would call heavy construction crosses it more easily than people expect once you count the staging area, the access route and the whole disturbed footprint rather than just the planted area. A large estate, an HOA common area conversion, a school ground, a park: these get to an acre.

Above that line the job needs a SWPPP, written by a QSD and implemented under a QSP. Those are qualifications held by people, and the practical question is whether you have that person on call before you bid, because the plan and the implementation are both priced items and both are inspection targets. The California stormwater and SWPPP guide covers what coverage involves.

There is a waste side too. CALGreen requires at least 65 percent construction and demolition waste diversion, and a turf removal job produces real tonnage: sod, old concrete, broken pavers and green waste are all divertible streams, and the documentation is what gets counted. Title 24 and CALGreen for contractors covers the mandatory measures.

What a C-27 lets you sign for, and where it stops

The classifications live in the 16 CCR 832 family, and the rule underneath them is that work outside the classification you hold is not permitted (BPC). Landscaping is broad, which makes the edges the thing to learn.

A C-27 covers the built and planted exterior: grading and soil preparation, irrigation and drainage, planting and lawns, decorative and functional site features, retaining and garden walls, walkways and patios. On a residential yard conversion that is essentially the whole job.

The other honest answer for some readers is B. A general building contractor takes a prime contract where at least two unrelated building trades or crafts are involved (BPC s.7057(a)). If what you sell is a pool, an outdoor kitchen with gas and power, a pergola and the planting around all of it, that is a multi trade project, and a B held alongside the C-27 is what lets you sign for the whole thing.

Heat is a jobsite rule with numbers on it

Nobody works more outdoor hours in an August afternoon than a landscape crew, and California writes the heat standard with specific triggers rather than general advice. Shade is required when the outdoor temperature exceeds 80 degrees. High-heat procedures start at 95 degrees, with construction named. Drinking water is one quart per employee per hour.

That is a truck loading question as much as a policy question: shade on the trailer, water on every truck, and a written Injury and Illness Prevention Program you can produce within 5 business days of a request, with tailgate meetings at least every 10 working days. The heat illness guide and the IIPP guide cover both.

Being the last trade on site costs you lien days

Landscape is usually the final trade. That is a scheduling fact everyone knows and a payment fact almost nobody prices in, because the owner starts closing the job out while you are still planting.

A Notice of Completion is recorded within 15 days of completion (Civ. Code Part 6). Once one is recorded, a subcontractor, supplier or lessor has 30 days to record a lien instead of the 90 days that would otherwise apply (Civ. Code s.8414). Your window shrinks by two thirds because of a document somebody else filed.

The habit that solves it is watching for the recording rather than waiting for a call. Drop your completion date into the California lien deadline calculator and you get both versions of your window on the day you finish. Private retention is released by the owner 45 days after completion with 10 days to pass it down (Civ. Code s.8812 and s.8814), covered in retention and release, and the mechanics lien deadline guide covers the rest.

Four years, two exams and the money to open the doors

Four years of journey-level experience inside the ten years before you file (16 CCR 825), counting a journeyman, foreman, supervising employee or contractor, with education offsetting up to three of those four years. The C-27 detail worth getting right is that the certification has to cover the full scope you run, irrigation and drainage as well as planting, because a statement that reads as maintenance work is the common reason a landscape application stalls. The experience requirement guide covers who can sign it.

Then two papers, Law and Business at about 115 questions and the C-27 trade exam at about 100, multiple choice, closed book at a PSI test center, calibrated per version rather than scored against a published fixed percentage, with the trade paper reaching into irrigation hydraulics, backflow, soils, drainage and plant material (the exams guide). Then the cash: $450 application fee, $200 initial license for a sole owner or $350 otherwise (CSLB fee schedule), the $25,000 bond (BPC s.7071.6), an additional $100,000 bond if you form an LLC (BPC s.7071.6.5), and workers compensation before the first employee, because a lapse suspends the license by operation of law on the day cover ends. Getting your CSLB license is the sequence, the bond and qualifier guide is the bond, and LLC versus sole proprietor is the entity call.

Residential work runs on home improvement contract rules (BPC s.7159): written above $500, prescribed headings and type sizes, a down payment capped at the lesser of $1,000 or 10 percent of the contract price, payments never running ahead of value delivered, and change orders written and signed before the extra work starts. On a $32,000 yard conversion, 10 percent is $3,200, so your legal maximum deposit is $1,000 and the answer is a milestone schedule, not a bigger check. The home improvement contract guide has the structure.

Where the C-27 work is

Los Angeles, San Francisco, San Diego and Sacramento publish building permits, and a permit for a multifamily building carries a landscape package nobody has bought yet. CEQAnet filings surface parks, campuses and public open space projects at the environmental stage, well before drawings go out. Caltrans advertises state highway work, where erosion control and planting establishment are real contract items. Public work over $1,000 is prevailing wage work needing DIR registration for you and every listed subcontractor before you bid, renewed each July 1. Where work is starting in California covers those sources, and the prevailing wage guide covers the wage side.

Put the acre and the dig ticket in the bid, not in the surprise column

The two rules that decide whether a retrofit job makes money are both knowable before you price it. Measure the disturbed area against one acre. Book the notification center against the schedule, not the shovel.

On AEC Stack there is no monthly subscription. The platform fee is 2.5 percent of each invoice processed through the platform, so the quoting and the tracking earn their keep on the jobs that actually get paid.

Take the biggest conversion you quoted this year, measure the full disturbed footprint rather than the planted area, and see which side of the acre it lands on. Then open a working demo business and set the next one up with the dig ticket and the completion date already in the file.
