Which school district?
The 2020 Census places all of the homes inside Los Fresnos city limits in Los Fresnos CISD, so the table above uses it. Your district depends on your exact address. Look it up on the Cameron Appraisal District property search. The share comes from 2020 Census housing counts within current boundaries, and new streets at the edges can differ.
The 2020 Census counted 2,702 housing units inside Los Fresnos city limits.
Units that tax only some homes
Cameron County Drainage District #1 (in the table) was on 15 of the 17 sampled homes inside city limits; a few parcels pay San Benito Drainage District #3 (2026 rate 0.147819, 2025 rate 0.137671) or Drainage District #4 (2026 rate 0.068252, 2025 rate 0.062551) instead. A public improvement district (PID) in a newer subdivision bills an assessment, not a tax rate; the title company can tell you if a lot has one.
A Los Fresnos mailing address can sit outside city limits, where there is no city tax and an emergency services district may tax instead. Your appraisal district record lists every unit on your home.
