About These Tools

Are these tools accurate?

These tools provide educational estimates and guidance based on general principles. They're not a substitute for professional assessment. Use them to orient your thinking, not as definitive answers.

How should I use checklist outputs in a dispute?

Use the tools as a practical checklist, not a legal argument. Keep your generated checklist, photos, notices, and receipts as part of a timeline. For legal remedies, combine tool output with your local rights guides and any landlord communication records.
