Terms of use

The ground rules for using CostFiled.

Last updated: August 28, 2026

Planning information only

CostFiled provides educational cost ranges and analysis for home-project planning. Figures are based on declared permit valuations or, where clearly labelled, indicative market benchmarks. They are not quotes, appraisals, inspections, tax advice, insurance advice, legal advice, or a guarantee of what your project will cost.

Use the original sources

Public records can be incomplete, revised, delayed, or classified incorrectly. Check the linked municipal source and consult a qualified local professional before making a financial, construction, or compliance decision.

Third-party links

CostFiled may link to public data portals, retailers, contractors, or other third-party sites. We may receive compensation from some commercial links. That does not change the methodology or the limitations of the figures. Third-party sites have their own terms and privacy policies.

Changes and corrections

We may update, correct, or remove content as source data and methods change. Questions about these terms or a possible error can be sent to support@aishortsystem.com.
