Terms of Service

Effective date: July 6, 2026

By using homebuildatlas.com you agree to these terms. If you don't agree, please don't use the site.

1. What the site provides

Free construction calculators and educational guides for project planning. Results are estimates based on the inputs you provide and documented assumptions; they are not professional advice, engineering services, or a guarantee of material quantities, costs, or outcomes.

2. No professional relationship

Nothing on this site creates an engineer–client, contractor–client, or advisory relationship. For structural design, deep excavation, retaining walls, chronic drainage problems, or code compliance, consult licensed professionals in your jurisdiction. See our Safety Disclaimer.

3. Permitted use

You may use the calculators and content for personal and internal business purposes. You may not scrape at scale, republish substantial portions of our content, misrepresent our results, or use the site in any unlawful way. Linking to our pages and citing short excerpts with attribution is welcome.

4. Intellectual property

Site content, design, original diagrams, and calculator implementations are © HomeBuild Atlas. Underlying mathematical formulas are public knowledge; our specific expression of them is not.

5. Advertising and affiliate links

The site displays advertising and may include affiliate links, disclosed in our advertiser and affiliate disclosures. Third-party sites you reach through ads or links have their own terms and policies.

6. Disclaimer of warranties

The site is provided "as is" without warranties of any kind, express or implied, including accuracy, fitness for a particular purpose, and non-infringement. We work to keep content accurate and reviewed, but errors can exist and conditions vary by site and jurisdiction.
