How to start a lawn care business in Ohio: vendor's license, spray rules and lawn signs

Ohio treats a lawn care company as a small taxpayer first and a pesticide business second, and both change how you start. The sales tax threshold is low enough that a one-truck company crosses it in a season. And if you spray weed control or fertilizer with herbicide, the state has a rule written for lawns that dictates your paperwork and your signs. This page covers what is different in Ohio. The main lawn care startup guide handles the national basics of equipment, routes and pricing. For Ohio's filings and formation costs, see our Ohio startup page.

Ohio sales tax starts at $5,000 in lawn care sales

Under Ohio Revised Code section 5739.01, landscaping and lawn care service is a taxable sale. The statute defines it as services such as planting, seeding, sodding, removing, cutting, trimming, pruning, mulching and aerating. It excludes a person who has less than $5,000 in sales of those services during the calendar year. In practice, a part-time mower can sit under the line for a summer, and a full-time company will not.

Section 5739.01 also makes mechanized snow removal taxable at the same $5,000 line, counted separately for that service. A mow-and-plow company still reaches taxable status sooner, and the statute's list is the thing to check if you add services. To collect tax you need a vendor's license, which your county auditor issues. The Department of Taxation announced that the one-time application fee for new vendor's licenses rose from $25 to $50 on April 9, 2025, under House Bill 366, so confirm the current amount with your auditor. Rates vary by county, so look up the rate for the county where each customer's property sits.

Cleaning the inside or outside of a building is a separate taxable service in Ohio under the same section, with its own $5,000 line, and the Department of Taxation's information release ST 2002-04 covers it. If you also pressure wash, the Department's release treats exterior building cleaning as taxable and says a separately billed item, such as a driveway, can be nontaxable. The Ohio Supreme Court narrowed the janitorial definition in 2018, so ask the Department how your jobs are classified and put each service on its own invoice line. Our guide to sales tax on services explains the general method.

Who needs an ODA license, and what a lawn pesticide license covers

Ohio Revised Code section 921.06 says an individual needs a commercial applicator license from the Ohio Department of Agriculture to apply pesticides for a pesticide business without direct supervision. A trained serviceperson working under a licensed applicator's direct supervision is treated differently. The director classifies licenses by pesticide-use category, a single license can cover several categories with no extra fee, and the statute says you may apply pesticides only in the categories where you are licensed. ODA sets the use categories by rule (rule 901:5-11-08), and lawn work falls under its turf and ornamental categories, so confirm the exact category for your services with ODA. Companies that apply pesticides for hire also need a pesticide business license from ODA, so confirm those steps with the Department. Under rule 901:5-11-04, commercial applicator licensing periods run October 1 to September 30.

The practical advice for a new company is to decide before you sell your first fertilizer-and-weed-control program. If a package includes a herbicide, someone on your team needs the license before the first visit. The licensed person can then train and supervise your crew members as servicepersons, so build a hiring plan around who holds the license. Our lawn care add-on services guide shows the services that do not trigger pesticide rules, such as aeration and overseeding, which you can sell while you study.

Ohio also has a fertilizer certification under Revised Code section 905.321. That statute is written around fertilizer applied for agricultural production, so it does not appear aimed at residential lawns. Confirm with the Department of Agriculture if you apply fertilizer on farm land.

Rule 901:5-11-09 sets signs, notices and records for lawn applications

This is the most distinctive Ohio rule for the trade. Rule 901:5-11-09, effective October 20, 2017, covers commercial applicators and servicepersons applying pesticide to residential, commercial and public lawns within municipal corporations or subdivided areas of townships. For a residential lawn, before or at application you give the owner or occupant written information:

• the brand or common name of each product, and its chemical type (fungicide, herbicide or insecticide);
• any special label instructions that matter to the customer;
• your company name and phone number, and the date and time of application;
• a statement that lawn posting signs must stay in place for twenty-four hours after the application.

You also post signs at conspicuous points, including common access points. The rule sets a sign at least 5 by 4 inches on adjacent sides, attached to the upper part of a dowel or similar support, with the bottom edge at least 14 inches off the ground and weatherproof for 24 hours. The layout is prescribed: the heading "LAWN CHEMICAL APPLICATION," a crossed-out dog graphic with "KEEP" and "OFF," and a notice that abutting residents may receive advance notice, followed by the company name and phone number. Logos and advertising are not allowed, and signs go within five feet of each access point where they are plainly visible. Your own employees may not remove signs during the 24 hours after application.

Neighbor notice works on request. If an occupant of an abutting residence has asked in writing for advance notice, you make a reasonable attempt to give the date, approximate time and your business name and phone number, on or before the business day before the application. You keep each requester's name, address and phone number for three years and must be able to show the director's inspectors the records. Properties separated entirely by a right-of-way, or touching the treated lot at a single point, do not count as abutting. Commercial lawns follow a lighter version of the rule: the information goes to the on-site person responsible, and signs are still posted. Applications on agricultural district property and some public utility and nuisance pest work are excluded.

For a small company this rule is a printing and software job. Build the written information into your application ticket or customer text, order the correct signs from a supplier, and keep one request list. A customer system makes this easier, which is the point of a custom CRM that stores each property's application history and neighbor requests.

Employees and workers' compensation

Ohio runs a state-fund system. Under Revised Code section 4123.35, private employers pay premiums into the state insurance fund administered by the Bureau of Workers' Compensation, and an employer with enough financial strength can apply to self-insure instead. Ask the Bureau how your first hire changes your status and how an owner's own coverage works for your entity type. Open a policy before your first hire starts work, since lawn crews use blades, trimmers and chemicals every day.

Season and first steps in Ohio

Mowing runs from roughly April through October. East of Cleveland, lake-effect snow makes plowing a real winter income source, while the south and Cincinnati see freeze-thaw and ice. Because snow removal is taxable in Ohio at the same $5,000 line, a mow-and-plow business that crosses the threshold should assume a vendor's license in the first year. Our mowing pricing guide helps you set prices that cover tax and fuel.

1. Form your entity and get an EIN, using our Ohio page for fees and filings.
2. Apply for a vendor's license through your county auditor before your sales reach $5,000.
3. Open a BWC policy before you hire.
4. Decide whether to offer herbicide or insecticide programs. If yes, get a commercial applicator license through ODA and a pesticide business license, and prepare the notice and sign kit.
5. Check with the building department in your city on any local registration.
6. Put a clear service and area page on your website. See our lawn care SEO guide.
