Privacy Policy
What we collect on this site, where it goes, and how to ask us to delete it.
Mostly DC, Maryland, and Virginia. Based in Bel Air, Maryland.
Who we are
East Coast CAD LLC, Bel Air, Maryland. Public email info@eastcoastcad.com. This page is for eastcoastcad.com (and this portal BIM viewer).
What we collect
When you request info, use chat, or run a permit preview we may collect first name, last name, email, a message, and a property address. Permit preview uses that address to look up public GIS and land-record data for the lot.
Where it goes
Request forms email info@eastcoastcad.com and create or update a contact in our East Coast CAD HubSpot account. Site chat can be saved encrypted on our server, keyed by a session cookie. Permit preview files are stored encrypted, not as public files.
Cookies and analytics
We use Google Analytics 4 (measurement ID G-QKLTFQZZ82) for traffic. HubSpot sets a tracking cookie so a later form can attach to the same visitor. Chat and preview use a cookie so your session can reload. Forms use a self-hosted Altcha check, not Google reCAPTCHA.
We do not sell this
We do not sell your name, email, or address. We do not put the street address or phone as scrapable text in the page source. Public GIS used for a preview is already public lot data.
How long
Leads stay in email and HubSpot while we are working with you or as the law requires. Encrypted chat and preview files are kept so we can finish the job, then we can delete them if you ask.
Your asks
Email info@eastcoastcad.com to see, correct, or delete what we have. Maryland company. This is how the site actually works, not a generic template.
Terms of Use
How the drawing sets work. Permit sheets are not surveys. Preview is not the deliverable.
Mostly DC, Maryland, and Virginia. Based in Bel Air, Maryland.
The work
East Coast CAD LLC sells CAD and BIM drawing sets: permit plans, shop drawings, mechanical, as-builts, scan-to-BIM, exhibits, and custom programming. Quote by the set. A quote is not a contract until we both agree in writing or by email.
Permit sheets are not surveys
Permit plans are compiled from the recorded plat and public records, with the house, proposed work, and setbacks drawn in CAD. They are not a field survey and not a sealed survey unless we say so in writing. If the county requires a licensed surveyor, a new recorded plat, or the old plat does not match, that is extra work by a surveyor, not this sheet.
Online preview
The address preview is a blurry, stamped image so you can confirm the lot. It is not the deliverable. Request drawing is $75. GIS and satellite can be wrong. You still verify against the recorded plat.
No permit guarantee
We draw. The county or AHJ decides the permit. We do not guarantee approval, review comments, or that an official will accept a compiled plat in place of a sealed survey.
Your files
You warrant you may send us the address, plat, and job files. Keep your own copies. Finished CAD remains our work product until the set is paid, then you may use it for that job.
Site chat and forms
The site agent answers from this company’s service copy. It is not a licensed surveyor, lawyer, or county reviewer. Forms go to info@eastcoastcad.com.
Law
Maryland law, without conflict-of-law rules. Bel Air, Maryland. Email info@eastcoastcad.com. Last updated 30 August 2026.
