Collin County is now in Censum's Texas build layer.
The current import includes **500,893 Collin County parcel rows** and **429,267 geometry rows**. It also includes appraisal and appeal-history data, but no Texas sales rows in the current primary parcel-sales table.
That means Collin is a major build target, not a finished public Censum checker lane. The homeowner message should be deadline, evidence, and exemption hygiene.
Quick read for Collin homeowners
- **Status:** major Texas build market with parcel, geometry, appraisal, and appeal-history coverage, but no primary sales rows yet.
- **Best first move:** preserve the May 15, 2026 protest deadline if the notice value looks wrong.
- **Common mistake:** waiting for a perfect comp analysis and missing the protest window.
- **Where Censum helps:** turning protest urgency into a cleaner evidence and fee decision, starting with homestead and record checks.
The 2026 deadline is real
Collin Central Appraisal District says the **2026 protest deadline for real property is May 15, 2026**.
That is four days from today, May 11, 2026. The deadline pressure changes the advice. Homeowners should not wait for a perfect model score if they already know they need to preserve protest rights.
The first move is to verify the notice, account, and deadline with Collin CAD.
What to check before filing
Collin homeowners should make a fast pass through:
- Appraised value.
- Market value change.
- Homestead exemption.
- Property characteristics.
- Recent purchase price, if applicable.
- Condition issues.
- Comparable sales or unequal appraisal evidence.
Texas protests are not just about saying the number feels high. The ARB process gives the homeowner and appraisal district a chance to present evidence.
What Censum can add
Collin's build size gives Censum room to help homeowners triage protest potential. But because sales coverage is still missing in the primary table, the near-term product should not pretend it has a complete market-comps engine.
The useful lane is:
- Preserve the deadline.
- Check exemptions and property facts.
- Organize the evidence.
- Decide whether paid help is worth it.
That is still valuable because many homeowners either miss the deadline or sign up for help before understanding their own evidence.
Fee math before an agent
If a protest is based on a recent purchase or obvious record issue, a contingency fee may be expensive relative to the work. If the case requires tight comps, ARB prep, or a formal hearing strategy, paid help may be rational.
The evidence should drive the decision.
Next step
If you own in Collin County, join intake, verify the deadline with Collin CAD, then use the Texas deadline guide and ARB evidence checklist to organize the protest file.

Censum note
Censum is building Texas county coverage as education and intake first. Collin County is in the build layer, but homeowners should verify official deadlines and filing rules directly with Collin CAD.
