Landscaping Business License Requirements in Texas (Dallas-Fort Worth Guide)

The short answer for Texas

No general landscaping license exists in Texas. TDLR, the state's main licensing agency, regulates 39 industries, and landscaping, lawn care, and tree trimming are not on the list (TDLR). You can legally mow, edge, plant, mulch, and haul brush for money tomorrow.

The licensing kicks in at two specific lines. Cross the chemical line, meaning you apply regulated herbicides or restricted-use pesticides for hire, and the Texas Department of Agriculture requires a commercial applicator license. Cross the water line, meaning you sell, install, repair, or even consult on irrigation systems, and TCEQ requires a Landscape Irrigator license. Stay on the mowing side of both lines and your only state obligations are a free sales tax permit and whatever business entity you choose.

The rest of this guide covers exactly where those lines sit, what each city in DFW charges, and what it costs to get fully legal.

State licenses that actually apply

Texas Department of Agriculture: the pesticide line

This is the license most lawn care operators in DFW actually need and do not have. If your crew applies restricted-use or state-limited-use pesticides or regulated herbicides for compensation, including the lawn and ornamental work under category 3A, TDA requires a commercial applicator license (TDA form PA-401 instructions).

The numbers:

• License: $200, valid one year, renewed annually (TDA PA-401 instructions). The form instructions carry a 1/1/16 revision date, so confirm the current fee at 800-835-5832 before you mail a check.
• Exams: $64 per category exam (TDA). You must pass the General Standards exam plus at least one category exam, so budget $128 minimum in testing.
• Continuing education: 5 CEUs per year to recertify (TDA).
• Business registration and financial responsibility. The applicator business itself registers with TDA and must show liability financial responsibility of $100,000 property damage plus $100,000 bodily injury per occurrence, or a $200,000 minimum general aggregate (TDA).
• Vehicle decals. Landscape-maintenance applicator businesses must put a TDA applicator business ID decal on every motor vehicle used in the work, available at TDA regional offices (TDA).

In practice the sequence looks like this. Pass the General Standards exam at $64. Pass the category exam that matches your work, which for lawn and ornamental spraying is category 3A, at another $64. Submit the license application with the $200 fee. Register the business with TDA and document the $100,000/$100,000 financial responsibility, which in the real world means a call to your general liability carrier for a certificate. Pick up vehicle decals at a TDA regional office and put one on every truck that carries spray equipment. Then book 5 CEUs each year before renewal, because the license expires annually and the CEU requirement does not pause for a busy season.

The exemption that saves most maintenance crews: applicators who apply only fertilizer need no license from TDA or the Structural Pest Control Service (TDA). Straight fertilizer is fine. Weed-and-feed is not, because the "weed" half is a herbicide.

There is a second door into legal spraying. TDA's Structural Pest Control Service licenses companies treating pests in and around structures, which covers fire ant, grub, and mosquito work at homes. That route costs a $300 SPCS business license plus a $125 certified applicator license and $64 per exam category (SPCS fees). Which route fits depends on your service mix. The agricultural side covers spraying the lawn and ornamentals themselves; the structural side covers pest treatments around the house. Many full-service lawn companies end up holding both, and the SPCS fee page has been in effect since 1/1/2016, so treat those numbers the same way you treat the PA-401 figure: current as published, worth a confirming phone call before you build a price sheet on them.

TDA also issues a noncommercial applicator license for people who apply regulated products as part of a job without selling application services to the public. The current dollar fee for that license was not on the pages pulled for this guide, so if that is your situation, get the number from TDA directly at 800-835-5832 rather than trusting a blog.

Penalties for skipping this: TDA administrative penalties run up to $5,000 per violation, and each day a violation continues can count as a separate violation (Ag. Code Sec. 76.1555). Civil penalties run $50 to $10,000 per violation, capped at $25,000 per single incident (Ag. Code Sec. 76.156). One season of unlicensed weed treatments can cost more than a decade of $200 renewals.

TCEQ: the irrigation line

TCEQ requires a Landscape Irrigator license to sell, design, install, maintain, alter, repair, service, inspect, or consult on irrigation systems in Texas (TCEQ). Read that verb list again. "Consult" and "repair" are on it. Swapping a broken valve on a customer's system is licensed work.

The numbers:

• License: $111 application, $111 renewal, 3-year term (TCEQ).
• Continuing education: 24 hours per 3-year term (TCEQ).
• Irrigation Technician: $111, 3-year term, 16 hours CE. This crew-level license lets an employee connect systems to the water supply, including the backflow device, and work under a licensed irrigator's supervision (TCEQ). One licensed irrigator plus technician-licensed crew members is how real irrigation companies staff, because the irrigator does not have to stand over every trench if the person making the water connection holds the technician card.
• Exemptions: licensed plumbers, and property owners working on their own home (Occ. Code Sec. 1903.002). This is why a plumbing company can legally install sprinklers without a TCEQ card, and why your customer can repair his own system even though you cannot touch it for him without the license.

One caution on city rules. You may have read that Texas cities over a certain population are required to run irrigation permit and inspection programs. That claim circulates on contractor forums constantly, but it was not verifiable on the TCEQ pages pulled for this guide, so it is not printed here as fact. [VERIFY: the population-threshold rule against 30 TAC 344 or Occ. Code 1903 before repeating it to a customer or a city inspector.] What is verifiable is that every DFW city covered below runs its own irrigation permitting, whatever the statutory trigger.

Penalties here are the sharpest in this trade. Installing an irrigation system without a license is a Class C misdemeanor (Occ. Code Sec. 1903.256), and TCEQ can assess administrative penalties of up to $5,000 a day per violation for unlicensed work under its occupational licensing chapter (Water Code Sec. 7.052). A "quick sprinkler repair" side line without the license is a criminal citation plus a five-figure fine exposure per week.

TDLR: nothing applies

Worth stating plainly because competitors' pages fudge it. TDLR licenses 39 industries, from air conditioning contractors to electricians, and no landscaping, lawn care, arborist, or tree-trimming program is among them (TDLR). There is no Texas landscaping license to buy and no course you are required to take. Anyone selling you one is selling you nothing. The one TDLR adjacency to watch: landscape lighting that involves electrical wiring is electrician territory. [VERIFY: whether low-voltage landscape lighting falls under a TDLR electrical exemption before selling it as a service.]

The Comptroller: landscaping and lawn care are taxable

This is the requirement that catches more DFW lawn crews than any license. Landscaping and lawn care are taxable services in Texas. Planting or removing plants, pruning, spraying, fertilizing, mowing, trimming, and edging all require you to collect state plus local sales tax on the total charge (Comptroller Pub. 94-112). The sales tax permit itself is $0 (Comptroller).

Note what is deliberately not printed here: the exact percentage. Pub. 94-112 says to collect state plus local tax on the total charge, and local rates vary by where the work happens. [VERIFY: the current state and local rates for your service addresses on the Comptroller's site before setting the tax line on your invoices.] Likewise, if you do landscaping for homebuilders on new construction, the tax treatment of that work was not extracted for this guide. [VERIFY: new-construction treatment in Pub. 94-112 and 94-116 before quoting builder contracts.]

Two carve-outs matter:

• The small-operator exemption. A self-employed individual with no employees who grossed $5,000 or less in the most recent four calendar quarters does not have to collect tax. Cross the threshold and you must start collecting on the first day of the next quarter (Pub. 94-112). This protects the teenager with a push mower, not a business. One employee or one decent month ends it.
• The nontaxable list. Mowing pipeline or highway rights-of-way, trimming trees away from power lines, farm and forest land work, and mowing cemeteries are not taxable. Landscape design is nontaxable if you itemize it separately on the invoice (Pub. 94-112). If you hold contracts on that list, do not charge tax on them.

Entity paperwork: the boring $300 that protects everything

None of this is a license, but it is the paperwork stack every legal operator carries, so here are the numbers. A Texas LLC costs $300 to form with the Secretary of State on Form 205, and a statewide assumed name certificate on Form 503 runs $25 if your LLC operates under a trade name (Texas SOS). Sole proprietors who skip the LLC file an assumed name certificate at the county clerk instead: $23 in Dallas County, $20 in Tarrant County, $18.50 in Collin County (Dallas County Clerk).

The LLC also puts you into the Texas franchise tax system, which sounds worse than it is. For 2026-2027 reports, no tax is due under $2,650,000 in annualized revenue (Comptroller). A landscaping company under that line files the report and owes nothing. Given that a lawn crew's biggest legal risks are a mower-thrown rock and a chemical drift claim, the $300 liability shield is the cheapest protection on this page.

City-by-city DFW requirements

No DFW city licenses landscaping as a trade. What cities regulate is permit-triggering work, and for this trade that means two things: irrigation systems and retaining walls. Routine mowing, planting, and bed work need no permit anywhere in the metro. Here is each city's actual paperwork.

Dallas

• Contractor registration: $120 per year with Building Inspection, listed under Other Trade Contractors on the city fee schedule, required before you pull permits (Dallas BI fee schedule). Register through the DallasNow portal.
• Permit triggers: irrigation systems and retaining walls. There is no dollar threshold; the trigger is the type of work. Building permit fees are value-based with a $100 minimum (Dallas BI fee schedule).
• Irrigation permit cost: the fee schedule lists no separate lawn-sprinkler line. Call Building Inspection at 214-948-4480 for the current permit cost before quoting Dallas irrigation work.
• If you lease a shop or yard: a certificate of occupancy is required for first use, change of use, or change of tenant, at a $375 general CO permit fee through DallasNow (Dallas CO page). Home-based crews skip this.

Fort Worth

• Contractor registration: $168.75 per year, first year and renewal, with Development Services (Fort Worth development fee schedule).
• Lawn sprinkler permit: $113.40 per system, a plumbing-class permit under fee schedule Table 1-I, pulled by a licensed irrigator or plumber. The schedule was set by Ord. 27191-09-2024 (same schedule).
• Threshold: none. The trigger is work type: sprinkler systems and structures, not routine landscaping.
• Sole proprietor trade name: Tarrant County assumed name certificate, $20 (county clerk fees).

Arlington

• Business registration: $100 for one year or $175 for two, recorded with the Building Official (Arlington fee schedule).
• Irrigation permits: $125 residential, $175 commercial for a new potable-water system. Expanding an existing system costs a $100 base plus $25 per zone valve over two, capped at $200 (same schedule).
• Threshold: none. Irrigation is permitted per system; retaining walls are permitted on valuation.

Plano

• Irrigation contractor registration: $100 per year (Plano fee schedule, Ord. 2025-11-4).
• Lawn irrigation permit: $175 residential, $260 commercial, per backflow device (same schedule). Plano's published schedule shows both old and new rate columns, $165 and $250 under the prior ordinance, and the $175 and $260 figures here are the current Ord. 2025-11-4 rates.
• Retaining wall permit: $75 (same schedule).
• Sole proprietor trade name: Collin County assumed name certificate, $18.50 (county clerk fees).

Irving

• Irrigators are on Irving's must-be-licensed list, alongside electrical, mechanical, and plumbing trades, and general contractors register with the city (City of Irving FAQ).
• Registration fee: not published online. Call Building Inspections at 972-721-2371 before your first Irving job. The trigger is licensed-trade work, not a dollar amount.

Frisco

• Contractor registration must be valid to work in Frisco and pull a permit (City of Frisco FAQ).
• Registration fee: not published online. Call 972-292-5301.
• Retaining wall permit: $150 per wall. No dollar threshold is published; the trigger is permit-type work.

McKinney

• Contractor registration: $0. Licensed contractors register before permits issue, but McKinney charges no registration fee (McKinney contractor registration).
• Irrigators and backflow testers register with the Water/Wastewater Department, and irrigation permits file through the city's CSS portal. The permit fee is not published on the irrigation page; call 972-547-7360.

Denton

• Irrigation contractor registration: $66 per year (Denton permit and fee schedule).
• Lawn sprinkler permits: $118 residential, $249 commercial, $48 alteration (same schedule).
• Retaining walls: $1.08 per linear foot plus a $141 plan review (same schedule). Denton's schedule is dated 10/08/2025, the freshest of the eight cities.

Total cost to get legal

Start with the state layer, which travels with you across every city:

Item	Cost	Applies to
Texas LLC, Form 205	$300 one time (SOS)	Everyone who wants liability protection
County DBA instead (sole proprietor)	$23 Dallas Co. / $20 Tarrant Co. / $18.50 Collin Co. (Dallas County Clerk)	Everyone skipping the LLC
Sales tax permit	$0 (Comptroller)	Every crew over the $5,000 exemption
TDA commercial applicator license	$200/yr + $128 exams (General Standards + 1 category at $64 each) (TDA)	Crews spraying herbicides or restricted pesticides
TCEQ Landscape Irrigator license	$111 per 3-year term (TCEQ)	Crews selling any irrigation work
Franchise tax	$0 owed under $2,650,000 revenue for 2026-27 reports (Comptroller)	Every LLC files the report anyway

Then add your city layer:

City	Contractor/irrigation registration	Residential irrigation permit	Retaining wall permit
Dallas	$120/yr	Call 214-948-4480	Value-based, $100 minimum
Fort Worth	$168.75/yr	$113.40 per system	Per fee schedule
Arlington	$100/yr or $175/2 yr	$125 ($175 commercial)	Valuation-based
Plano	$100/yr	$175 per backflow device ($260 commercial)	$75
Irving	Call 972-721-2371	Call 972-721-2371	Not published
Frisco	Call 972-292-5301	Call 972-292-5301	$150 per wall
McKinney	$0	Call 972-547-7360	Not published
Denton	$66/yr	$118 ($249 commercial, $48 alteration)	$1.08/LF + $141 plan review

What the stacks actually total:

• Mow-and-blow crew (no chemicals, no irrigation): $18.50 to $300. A county DBA at $18.50 to $23 if you stay a sole proprietor, or the $300 LLC if you want the liability shield, plus the free sales tax permit. Zero licensing. No DFW city registers you if you never pull a permit.
• Full-service lawn care with weed control: about $630 in year one. The $300 LLC plus the $200 TDA license and $128 in exams comes to $628, before whatever your insurer charges to document the $100,000/$100,000 financial responsibility and before the vehicle decals.
• Landscaping plus irrigation, working Dallas and Plano: about $960 in year one. The $628 chemical stack plus the $111 TCEQ license, $120 Dallas registration, and $100 Plano registration totals $959, before per-job permit fees.

What you can do without a license

The direct answers, since this is the question most searchers came for:

Legal with no license anywhere in Texas: mowing, edging, blowing, leaf cleanup, planting beds, shrubs, trees, and sod, spreading mulch, applying straight fertilizer (TDA), tree trimming and removal, and landscape design drawings that stay away from irrigation. Your only obligations are tax collection and your entity paperwork.

Illegal without a license, with the penalty attached:

• Spraying regulated herbicides or restricted pesticides for hire. TDA administrative penalties reach $5,000 per violation with each day countable as a separate violation, and civil penalties run $50 to $10,000 per violation up to $25,000 per incident (Ag. Code Ch. 76).
• Any irrigation work: install, repair, service, or consulting. Class C misdemeanor (Occ. Code Sec. 1903.256) plus TCEQ administrative penalties up to $5,000 a day (Water Code Sec. 7.052).
• Skipping sales tax past the $5,000 exemption. The Comptroller audits service businesses, and uncollected tax comes out of your pocket with penalties and interest.

The practical scope rule: a maintenance crew that keeps chemicals at fertilizer strength and subs out sprinkler repairs to a licensed irrigator never needs a state license at all.

Four numbers you still have to get by phone

Honest guides say what they do not know. Four fee figures in this market are not published online, and any page that prints them anyway is guessing:

1. Irving contractor registration. The city's FAQ confirms the requirement but posts no fee. Building Inspections: 972-721-2371.
2. Frisco contractor registration. Same situation. Development Services: 972-292-5301.
3. McKinney irrigation permit. Registration is free, but the permit fee is not on the irrigation page. Water/Wastewater: 972-547-7360.
4. Dallas lawn sprinkler permit. The published fee schedule has no dedicated sprinkler line. Building Inspection: 214-948-4480.

Make the calls before you quote work in those cities, write the answers on the printed copy of this page, and check the date on every fee schedule you download, because DFW cities revise them on ordinance cycles, not on your schedule.

Three reasons DFW landscaping companies work with On The Map

1. You rank in Google Maps and local search, where lawn and landscape customers actually pick. Nobody comparison-shops mowing crews for a week. They search "landscaping near me," look at the top 3 map results, and call the one with reviews. If that is not you, the recurring weekly accounts in your own neighborhood go to whoever it is.
2. A website that turns searches into booked jobs. Clear service list, your TDA and TCEQ license numbers displayed where they build trust, click-to-call, and a quote form that works from a phone in a truck. The site has one job: converting the search into a scheduled visit.
3. Done-for-you while you stay on the tools. You are running crews through a Texas summer and keeping 5 CEUs and a 24-hour CE cycle current. You do not have hours for SEO. The ranking work happens without you touching it.

What staying invisible costs

Run the numbers the way an enforcement officer or a competitor would. On the compliance side, one unlicensed sprinkler repair carries a Class C misdemeanor plus TCEQ exposure of up to $5,000 a day (Water Code Sec. 7.052), and unlicensed spraying carries TDA penalties up to $5,000 per violation, per day (Ag. Code Sec. 76.1555). Getting legal costs $111 and $200. The math is not close.

On the revenue side, the licensed competitors above you in the map pack print their TCEQ irrigator number and TDA license on their sites, and that credential display wins the customer who just read a page like this one. Every recurring maintenance account that signs with a ranked, credentialed competitor instead of you keeps paying them every month for years, and lawn care is a trade where the whole business model is the recurring account. No countdown timer here. Just the arithmetic of who gets found first, this week and every week after.
