Guides & Tools for Judging a Purchase Without Being Sold a Floor Plan
The doors are the smaller half of this site. The larger half is here: the decision tools a buyer needs before any factory's name matters.
How modular approval works
The three approval machines, end to end — the state program and its label, the approved third-party agency, the local counter's retained scope — and what each one does to your schedule.
Factory scope vs. site scope
The split drawn line by line — box, seam, site — the orphan lines that sink schedules, and how the loads, the seals, and the inspections divide.
The scope-split checklist
Every line item of the purchase — and the test question that assigns it an owner before signing.
The buyer's dossier
What to gather before you sign, item by item — and what each fact protects you from.
License lookup, all 51 states
The verification step that outranks every other — including this site's.
Who Publishes This Directory
Published by Apex Grid Engineering PLLC. The firms evaluated and listed on this site today are the publisher's own family of brands — this is an affiliated directory, not a neutral referee. The methodology below is the standard any engineering firm can be measured against, and it is the standard we hold our own firms to in public. Presentation order on this site is the publisher's choice and an experiment in what helps buyers decide — it is not an objective quality verdict, and no firm pays for placement. Coverage claims are limited to licensure the operator's bench actually holds, stated per state. No reviews, ratings, or project claims are published for any firm unless they can be documented — this site explains how a buyer should judge a modular purchase and publishes the publisher's methodology assessments; it does not publish customer reviews, and you will find none invented here.
Operated by Apex Grid Engineering PLLC. Founder & CEO: Jeremy “Chico” Mills — serial entrepreneur and USAF veteran. Jeremy is the founder and chief executive; he is not a licensed professional engineer, and no page on this site implies otherwise. The engineering behind the listed firms is performed and sealed by their licensed PE benches.
