Terms of Service

Last updated: November 15, 2026

These Terms of Service ("Terms") govern your use of ILX Drawings, the online residential drawing service at this website (the "Service"), provided by ILX Studio, LLC ("ILX Studio", "we", "us"). By creating an account or using the Service you agree to these Terms. If you use the Service for a firm, you confirm that you may accept these Terms on its behalf.

1. The Service

ILX Drawings is a design aid for engineers, architects and residential designers. From a questionnaire and the model you edit, it lays out residential floor plans and produces permit drawing sets (architectural, structural, mechanical, electrical, plumbing and site sheets), a 3D model, code checks based on the International Residential Code (IRC) and related references, energy code tables, and calculation packages, exported as PDF and DXF. Features are added and changed as the Service develops.

2. Professional responsibility

The Service does not replace professional judgment, and it does not provide engineering or architectural services. You, or the engineer or architect of record you work for, are solely responsible for the input, for checking the results, for every drawing, calculation and document you issue, and for compliance with the building code adopted by the jurisdiction and its amendments. Drawings and calculations produced with the Service must be reviewed, completed and sealed by a licensed design professional where the jurisdiction requires it. Read the Disclaimer, which is part of these Terms.

3. Accounts

  • ILX Drawings uses your ILX Studio account, the same account as ILX Calcs and ILX Connection.
  • You must give accurate account information and keep your password and your API tokens confidential.
  • You are responsible for activity under your account, including activity through your API tokens. Tell us promptly at services@ilxstudio.com if you suspect unauthorized use, and revoke any token you no longer need.
  • One account is for one person. Accounts may not be shared.

4. Trial, subscriptions and payment

  • New accounts receive a trial period of 30 days from the confirmation of their email address.
  • After the trial, editing requires a paid subscription, monthly or yearly, per user (one seat per person), at the prices shown on the Pricing page when you subscribe, in US dollars, plus any applicable taxes. Until subscriptions are offered, the Pricing page says so. When the trial or a subscription ends, your projects stay available to view, print and download.
  • Founder pricing. If a founder offer runs, the first subscribers it names pay the discounted founder price shown on the Pricing page. A founder keeps that price for every renewal for as long as the subscription stays active without interruption. If the subscription is cancelled or lapses, the founder price ends, and a later subscription is at the price of the day.
  • Purchases are processed by Stripe, which sells the subscription to you as merchant of record and reseller. Stripe handles checkout, sales tax or VAT, receipts and payment support. Your card details go to Stripe and never reach ILX Studio.
  • Subscriptions renew automatically until cancelled. You may cancel at any time; the subscription then ends at the close of the paid period.
  • We may change prices for future periods with at least 30 days' notice. Price changes do not apply to an active founder subscription.

5. Your content

Your projects, inputs, uploaded images and detail sheets, drawings and reports ("Your Content") remain yours. You give us permission to store, process and back up Your Content only to provide the Service to you. We do not sell Your Content or use it to market to others. You confirm that you have the right to upload what you upload, for example a survey, a plan you trace over or your firm's standard details.

6. Acceptable use

You agree not to: attempt to access other users' data; interfere with or overload the Service, including through API tokens; reverse engineer the Service except where the law allows; resell or provide the Service to third parties; or use the Service for any unlawful purpose.

7. Third-party services

Some features look up public data from third parties, for example an address with the US Census geocoder, seismic values and maps from the US Geological Survey, or a parcel from a county map service. Those services are provided by others, may be unavailable or inaccurate, and are not under our control. Check their results before you rely on them.

8. Availability and changes

We work to keep the Service available and accurate, but it is provided without a guarantee of uninterrupted operation. We may update, add or remove features. We will give reasonable notice of changes that materially reduce the Service.

9. Intellectual property

The Service, its software, design, standard details and documentation belong to ILX Studio, LLC and its licensors. You may use the drawings and documents you produce with the Service for your projects. The codes and standards the Service refers to (for example those of the International Code Council, ACCA, NFPA, AWC and ASCE) are the property of their publishers. ILX Studio, LLC is not affiliated with or endorsed by any of them.

10. Warranty disclaimer

To the extent permitted by law, the Service is provided "as is" and "as available", without warranties of any kind, express or implied, including fitness for a particular purpose and non-infringement.

11. Limitation of liability

To the extent permitted by law, ILX Studio, LLC is not liable for any indirect, incidental, special, consequential or punitive damages, or for loss of profits, data or business, arising from the use of the Service. Our total liability for any claim is limited to the amount you paid for the Service in the 12 months before the claim.

12. Termination

You may close your account at any time. We may suspend or close accounts that breach these Terms. On closing, you may request an export of Your Content within 30 days, after which it may be deleted.

13. Governing law

These Terms are governed by the laws of the State of North Carolina, USA, without regard to conflict-of-law rules.
