Can ChatGPT write your job posts? ChatGPT Job Post Guide for Trade Contractors in DC, MD and VA

By Capital Growth Studio · Published · 5 min read

This article shows how to use ChatGPT to write a trade job post. It also lists what to check on pay and licenses in DC, Maryland and Virginia before you publish the post.

An AI tool in the center links a prompt, a job post and a license certificate, while a warning marks the pay range to check before the post goes live.

ChatGPT is an AI tool that writes text from a prompt, the request that you type. Yes, ChatGPT can write a first draft of a trade job post. But it writes from patterns, not from your facts. So a person checks every draft.

As of October 2026, three laws require pay information in job posts. They are D.C. Code § 32-1453.01, Maryland Labor and Employment § 3-304.2 and Virginia Code § 40.1-28.7:12.

Laws change, so check the current rules before you act (links at the end of this article).

What must a job post show in DC, Maryland and Virginia?

As of October 2026, the three laws require:

WhereLawWhat the law requires
VirginiaCode § 40.1-28.7:12The wage, salary or wage or salary range for the position, "in each public and internal posting for each job"
MarylandLabor and Employment § 3-304.2"The wage range and a general description of benefits and any other compensation offered for the position," in each public or internal posting, for work done at least partly in Maryland
DCD.C. Code § 32-1453.01"The minimum and maximum projected salary or hourly pay in all job listings and position descriptions advertised," and disclosure of "the existence of healthcare benefits" before the first interview

As of October 2026, the Maryland Department of Labor's FAQ accepts "$30 an hour" but not "$30+ an hour." The Virginia and Maryland statutes also bar seeking an applicant's wage history. D.C. Code § 32-1452 bars screening on it. The Maryland FAQ also treats posts on Indeed or LinkedIn as postings.

Our guide to pay ranges in DC, MD and VA job posts compares the three laws.

What do AI drafts get wrong?

In trade job posts, look for five errors:

  • Invented requirements: degrees, certifications or years of experience that you did not ask for.
  • Missing or vague pay: "competitive pay" or "up to $40 an hour" instead of a range.
  • A pay history question: for example, a question about current salary.
  • Extra words in the title: as of October 2026, Google's job data rules require "the title of the job only."
  • Wrong license names: each jurisdiction names HVAC licenses in a different way.
WhereHVAC license names
MarylandApprentice, Journey, Journey Restricted, Limited Contractor, Master Restricted, Master Contractor
VirginiaJourneyman or Master Heating, Ventilation & Air Conditioning. The Residential HVAC tradesman license excludes commercial buildings.
DCRefrigeration/Air Conditioning Apprentice Mechanic, Journeyman Mechanic and Master Mechanic, plus limited (LTD) and contractor licenses

What does a good prompt include?

Paste this prompt into your AI tool, and replace each bracket with your facts.

Write a job post for a [Commercial HVAC Service Technician]
at [company], a [mechanical contractor] in [city, state].

Use only these facts:
- Pay: [$X to $Y an hour]
- Benefits: [health, paid time off]
- Required license: [exact name and jurisdiction]
- Required certification: [for example, EPA Section 608 Universal]
- How to apply: [link to a short form]

Rules:
1. Do not add degrees, certifications, experience or duties.
2. If a fact is missing, ask me. Do not guess.
3. Copy the pay, benefits and license names exactly.
4. Title: the job title only.

Keep one approved sheet for each role, with the pay range, benefits and license names.

Where can you check the current rules?

Laws and regulations change, and amendments, court decisions or agency guidance can change how a rule applies. We checked the sources in this article on October 20, 2026. Before you act, read the current official text for each place where you work:

If your business works in any other state, we strongly recommend that you check that state's current law and its latest amendments, because they may change how these rules apply to you.

Frequently asked questions

Can ChatGPT set the pay range for a job post?

No. ChatGPT does not know your pay scale or your budget. As of October 2026, Virginia Code § 40.1-28.7:12 defines the range as one set in good faith. Give the AI the range that your company approved.

Can I paste an old job post into ChatGPT to update it?

Yes. Remove names and contact details first. Ask the AI to change only the wording. Then check the pay range against your current pay scale.
