Terms of Use

Last updated: 28 April 2026

By using BackyardADU.net you agree to these terms. They are short and written in plain English.

What this site is

BackyardADU.net is a free informational reference site about accessory dwelling units in California. We compile public data and provide cost estimates, zoning summaries, and builder directory entries.

What this site is not

• Not legal advice. ADU rules and zoning interpretations vary by jurisdiction and change frequently. Consult a licensed land-use attorney for legal questions.
• Not financial advice. ADU financing, ROI projections, and rental yield estimates are illustrative. Consult a licensed financial advisor for advice specific to your situation.
• Not engineering or contractor services. Cost figures are averages. Real construction costs depend on lot conditions, contractor pricing, finish levels, and timing. Always get multiple licensed quotes before signing a contract.

Accuracy

We make reasonable efforts to keep data current and accurate, but ADU rules, permit fees, and construction costs change. We do not warrant that any specific figure on this site is current or applicable to your situation. If you spot an error, email hello@backyardadu.net.

Builder directory

Builders listed on this site are pulled from the California State License Board public database. Inclusion is not an endorsement. License status changes — verify with the CSLB Instant License Check before contracting work.

External links

We link to external sites. We do not control or endorse the content of those sites and are not responsible for their accuracy.

Limitation of liability

BackyardADU.net is provided "as is" without warranties of any kind. To the maximum extent permitted by law, we are not liable for any direct, indirect, incidental, or consequential damages arising from your use of this site or reliance on its content.

Governing law

These terms are governed by the laws of the State of California.

Changes

We may update these terms. Continued use of the site after changes constitutes acceptance of the revised terms.
