Permit Routing
Don't call the appraisal district for a permit or an address; they'll send you elsewhere
The Starr County Appraisal District out on FM 3167 gets a steady stream of calls for things it simply doesn't handle, enough that it printed a sheet spelling them out. It can't issue your physical address, can't give you a survey, can't hand over a subdivision plat or a copy of a deed, can't tell you a subdivision's building restrictions, and can't issue a permit to move or build anything.
Each one comes with a forwarding address. Permits and addresses go to the Starr County Planning Department, or to your city's planning office if the property sits inside Rio Grande City, Roma, Escobares, or La Grulla. Plats, deed copies, and subdivision restrictions are the County Clerk's department, reachable at 956-716-4800.
One that bites mobile-home owners: the CAD won't combine a mobile home onto the land account without a Statement of Ownership and Location proving you own it as real estate. Sort that paperwork out before you expect one tax bill instead of two. The appraisal district is for value, exemptions, and ag or homestead questions; everything else routes to planning or the clerk.
