Nothing on this website constitutes a binding construction appraisal, licensed engineering opinion, home inspection report, legal advice, or building-code determination.
Homeowner responsibility
You are solely responsible for verifying contractor licenses, general liability and workers’ compensation insurance, local building permits, utility locating (including 811 and private underground lines), written contract terms, and on-site safety before authorizing residential work.
Acceptable use and intellectual property
Do not disrupt site availability, submit automated spam through the contact form, or republish full articles or calculator code without written permission from Ailu Studio. Short quotations with a direct link back to the source guide are welcome.
External links and updates
Links to government agencies, standards organizations, and technical references are provided for convenience. Local codes and manufacturer installation specifications change over time; always verify current rules with your local authority having jurisdiction (AHJ).
