San Marcos building permits now run through a newer portal
San Marcos moved building permit applications to a newer portal, with account setup, permit guides, solar notes, PRADU information, and inspection links to check before applying.
A San Marcos building permit now starts with the newer permit portal. Applicants need a free account before sending in a building permit application.
The older eTRAKiT page points permit users to the newer Clariti portal for NREL Solar App, commercial, and building permits. That change is worth noticing if you are following an old bookmark or advice from a past project.
There are helpful side paths too. San Marcos lists solar information, inspection links, building packets, and a Permit Ready ADU program. If solar work includes a reroof or panel upgrade, those pieces need separate permits, so the project label matters before the upload begins.
Before applying, pause long enough to name the work clearly. Is it solar, a panel upgrade, a reroof, a tenant improvement, an ADU, or a remodel? Hills, colleges, trails, business parks, and steady housing demand all shape the city. At the counter, the useful detail is still the exact work.
