Frequently asked questions for Fannin County
Who handles permitting for this jurisdiction?
Fannin County Environmental Development / Development Services is the identified county-level authority for this profile. Confirm that the property is in its service area before filing.

Begin with the online permit gateway listed in the application guide. If the portal does not recognize the address or project type, contact Environmental Development/OSSF: 903-583-7495; Development Services: 903-449-4220.
How long might review take?
N/A; the county requires review before Authorization to Construct, and the current application states permits are valid for one year from issue.
How are inspections scheduled?
Create an account and submit permitting materials and payment through MGO Online. For an OSSF, submit the application, site evaluation, technical/design documents, warranty deed, and required fee; Environmental Development must review them before Authorization to Construct. Confirm the ATC before beginning, then contact the office at least one working day before the required inspection before covering the system; a successful inspection results in Authorization to Operate.
Which codes and exemptions should I review?
The county materials identify local OSSF requirements under Texas Health and Safety Code Chapter 366 and 30 TAC Chapter 285, plus Fannin County subdivision/development regulations; no general countywide ICC building-code edition was verified. No broad cosmetic-work exemption list was published. OSSF permits cover qualifying septic construction, repair, and alteration; state exemptions such as qualifying 10-acre-rule systems, grandfathered systems, and defined emergency repairs should be confirmed with the county.
