Coverage

Six cities and towns to start

Allen, Frisco, McKinney, Plano, Prosper and Richardson, north of Dallas, Texas. We go by the full city limits, whichever county the address is in.

  • Allen
  • Frisco
  • McKinney
  • Plano
  • Prosper
  • Richardson

Addresses are placed by city limits, not the city in the mailing address. Outside these cities and towns the lookup says "not covered yet" and tells you which city to call. What each city covers

How it works

Three steps

  1. 01

    Enter the job

    Address, sign type, illumination and frontage.

  2. 02

    We match the rules

    We find the city and zoning district for the address, and the rules for that sign type.

  3. 03

    Check and file

    Each rule shows its code section, a short quote, a link and the date we last checked it.

Seconds, not days

The answer is on screen while you quote the job.

Quoted and linked

Every figure points to the section it came from.

No guessing

If a figure fails a check, we show "not confirmed" instead of a number.

One flat price

One flat monthly price. No charge per lookup.

Rules are taken from each city's published code using AI and checked automatically. They are not reviewed by a person, so check the linked section before you file. How the checks work
Pricing

One plan

Shop plan
$49 per month
  • All covered cities and sign types
  • Sign area worked out from your frontage, where the code uses frontage
  • Section, quote and link on every confirmed line

The lookup is free while we test it. Nothing is charged.

Leave your email to hear when the paid plan opens. Your email is used only for that.

Not legal advice. The city has the final say. Planned developments, master sign plans and special sign districts can override the general sign code.
