File your appeal by mail
How it works
You can appeal assessed property values once you receive your annual valuation notice. You'll need to present evidence that the assessor made an error in your appraisal. Evidence could include sales of comparable properties in your area.
Include all evidence with your appeal. With a prompt submission, you could get a reduction offer without attending a hearing.
Other types of evidence could include
- Info on similar properties that have sale dates close to the valuation date
- Proof of easements or other restrictions on our property
- Proof of development limitations on your property
- Proof that environmentally-sensitive areas exist on your property
- Professional cost estimates to fix any maintenance issues
Before you file your appeal
Contact the assessor's office to confirm any errors. An example would be if we listed the wrong number of bathrooms at your property. We're happy to review your valuation and answer your questions.
