Terms of Use
These terms govern your use of engineering-contracting-design.com, including its calculators and guides. They do not replace a signed design agreement or construction contract, which alone govern any work ECD performs for you.
Information on this site is general
Guides, cost tables, FAQ answers and project descriptions on this site explain how structural remodeling generally works on the Eastside and in Seattle. They are not engineering advice for your house. Whether a particular wall carries load, what size a beam must be or what a city will require for your project can only be determined by a licensed professional who has examined the property and the applicable code.
Calculators and estimates
The Permit Cost and Timeline Estimator, the Load-Bearing Wall Checker and the Addition Cost Calculator produce ranges and likelihoods based on the assumptions listed on each tool's page. Results are informational only. They are not a bid, a quote, a structural determination or a permit fee assessment. City fees are set by each jurisdiction and are confirmed only when the city assesses your application. Do not remove, cut or alter any wall based on a calculator result.
No professional relationship
Using this site, submitting a form or calling us does not create an engineer-client or contractor-client relationship. That relationship begins only when you and ECD sign a written agreement describing the scope of services.
Content ownership
Text, drawings, photographs and tools on this site belong to ECD — Engineering Contracting Design or are used with permission. You may link to any page and quote short passages with attribution. You may not copy the site's content, calculators or project photos for commercial use without written permission.
Links to other websites
We link to city building departments, state agencies and code publishers so you can check facts at the source. We are not responsible for the content of those sites, and a link does not mean they endorse ECD.
Reviews and submissions
If you send us photos, plans or other material through a form, you confirm you have the right to share it and allow us to use it to respond to your request. We will not publish your photos or project details without your written permission.
Limitation of liability
The site is provided as it is. To the extent Washington law allows, ECD is not liable for loss or damage arising from reliance on site content or calculator results without a signed agreement and a site evaluation by our professionals.
Governing law
These terms are governed by the laws of the State of Washington. Any dispute about this website is subject to the courts of King County, Washington.
