Step-by-Step: How to Protest in Bexar County
Step 1: Check Your Appraisal Notice
When your notice arrives, verify:
- Property address and legal description
- Square footage and lot size
- Building characteristics (bedrooms, bathrooms, etc.)
- Listed improvements and amenities
- Current vs. prior year values
Step 2: Evaluate If Protesting Makes Sense
Signs you should protest:- Assessment increased more than 8-10%
- Your $/sqft exceeds similar nearby sales
- You know of property issues BCAD doesn't
- Recent comparable sales support a lower value
- Your property has been over-assessed in prior years
- Assessment is at or below recent purchase price
- Your neighborhood has genuinely appreciated significantly
- No comparable sales support your position
Step 3: File Your Protest
Online (Recommended): File through BCAD's online portal. Fastest method with immediate confirmation. By Mail: Bexar Appraisal District P.O. Box 830248 San Antonio, TX 78283-0248 In Person: 411 N. Frio St. San Antonio, TX 78207Select "Value is over market value" as your protest reason—it's the most common and usually strongest argument.
Step 4: Gather Evidence
BCAD appraisers need data, not opinions. Build your case:
Comparable Sales (Most Important)Find 3-5 properties that:
- Sold in the past 12 months
- Are within your neighborhood or 1 mile
- Are similar in size (within 20%)
- Are similar in age and condition
- Sold for less than your assessed value
Document problems affecting value:
- Foundation concerns
- Roof damage or age
- Outdated major systems (HVAC, plumbing, electrical)
- Needed repairs with estimates
- Flood zone location
Check your property card for:
- Wrong square footage
- Incorrect room count
- Listed amenities you don't have
- Wrong construction quality rating
- Incorrect year built
Step 5: Attend Your Informal Hearing
Before formal ARB proceedings, BCAD offers informal hearings to resolve protests.
What to expect:- 15-30 minute meeting
- Present your evidence to a BCAD appraiser
- Opportunity to negotiate
- Most protests are resolved here
- Bring organized, printed evidence
- Lead with your strongest comparable sales
- Stay professional and fact-focused
- Know your target value before walking in
- Be prepared to negotiate
Step 6: ARB Hearing (If Needed)
If informal discussions don't work out:
- Formal hearing before the Appraisal Review Board
- More structured with sworn testimony
- Present your evidence systematically
- Board makes a binding decision
What Evidence Works in San Antonio
Tier 1: Strongest
- Comparable sales at lower values — Similar properties that sold for less than your assessment
- Appraisal errors — Incorrect property characteristics in BCAD's records
Tier 2: Strong
- Property condition documentation — Foundation reports, repair estimates, photos
- Recent market data — MLS showing prices, days on market
Tier 3: Supporting
- Unequal appraisal — Similar properties assessed lower
- Location factors — Busy street, flood zone, other negatives
San Antonio Neighborhood Considerations
North Central (Stone Oak, TPC, Champions)
Higher-value properties with more assessment variation. Strong comps are essential—focus on finding similar sales.Northwest (Helotes, Leon Springs)
Mix of older and newer construction. Condition-based arguments may work for older homes.Northeast (Schertz, Cibolo)
Parts are in Guadalupe County (different CAD). Verify which appraisal district covers your property.South Side
More affordable properties where smaller dollar reductions still represent meaningful percentage savings.Downtown/Midtown
Urban properties with unique characteristics. Comps may be harder to find—be creative but stay similar.Alamo Heights, Terrell Hills, Olmos Park
Independent cities within Bexar County. Same BCAD, but these areas have distinct market conditions.Common Mistakes San Antonio Protesters Make
1. Missing the Deadline
May 15 is absolute. Set calendar reminders starting in April.2. Using Online Estimates
Zillow and similar estimates aren't evidence. BCAD won't accept them. Use actual closed sales.3. Poor Comparables
A 1960s home doesn't compare to 2015 construction. Match property type, age, and condition.4. Emotional Arguments
"I can't afford this" or "This isn't fair" won't help. Stick to data.5. Not Checking BCAD Records
Simple errors in square footage or amenities are easy wins. Always review your property card.Special Considerations
Military Installations
San Antonio has multiple military bases. If you're military personnel with deployment or relocation, you may have additional protections and deadlines.Historic Properties
King William, Monte Vista, and other historic districts may have unique valuation considerations.Flood Zones
Parts of San Antonio are in flood zones. If your property is flood-prone, that affects value and should be part of your argument.Investment Properties
Rentals don't benefit from the 10% homestead cap. YoY increases can be substantial, making protests more valuable.After Your Protest
If Successful:- Reduced assessment = reduced taxes
- The reduction typically carries forward
- Consider protesting annually
- Your value cannot be raised during protest
- Options: binding arbitration, district court (rarely worth it for residential)
- Try again next year with updated evidence
