The legal process is identical for every zip in Collin County — Texas Tax Code applies countywide and CCAD appraisers handle each protest the same way. What changes by zip is the underlying evidence:
CCAD mails Notices of Appraised Value (NOAVs) to property owners across 75442 and the rest of Collin County in mid-April. Your notice lists this year's appraised value and last year's, and the protest deadline is printed on it — Texas law sets it at May 15 or 30 days after the notice was mailed, whichever is later.
The protest math is simpler than it sounds: would your home actually sell for the appraised value today? Recent sales in 75442 are the strongest answer — they're also exactly the data CCAD appraisers use, so they engage on the merits when you bring better comps than they brought.
File online through the portal linked from https://collincad.org, by mail to 250 Eldorado Pkwy, McKinney, TX 75069, or in person at the same address. Online filing is fastest. Texas recognizes two independent grounds — market value and unequal appraisal — and which one (or both) actually applies depends on comparable-sales math and a statistical equity analysis against your peers. Our reports run both analyses on your specific property and tell you which grounds the data supports.
Successful protests are decided on three categories of evidence: recent comparable sales of similar homes in 75442, an unequal-appraisal analysis showing your value is higher than peers, and any condition documentation that explains why your home is worth less than the mass-appraisal model assumes. Many cases settle here without a formal hearing.
CCAD starts with an informal review where one of their appraisers offers a settlement based on your evidence. Accept it if it's fair. Reject it and your case advances to a formal Appraisal Review Board hearing — three private citizens who hear both sides for 5–7 minutes each and rule.
