Do I need a permit for deck construction or replacement in San Benito?

Most likely yes. Deck construction or replacement usually requires a permit in Texas. Confirm the specifics with San Benito.

Texas Local Government Code 214.212 adopts the International Residential Code as it existed on May 1, 2012 as the municipal residential code. Section R105.2 of that edition exempts only a deck of 200 square feet or less that is no more than 30 inches above grade at any point, is not attached to the house, and does not serve the required exit door. Cities may amend that code by ordinance and may take up later editions, so an attached, raised, or larger deck should be treated as needing a building permit. Confirm the rules with your city building department. Outside city limits, the county standards in Local Government Code Chapter 233, Subchapter F cover only a new house or duplex on a vacant lot and additions that grow a home by more than 50 percent, and they do not require county approval before building. Confirm which office, if any, has jurisdiction over your lot. This deck is attached to the house or will have a roof. Where a small deck exemption exists at all, it covers only small, low, freestanding decks that do not serve the home's required exit door, so an attached deck falls outside it. A ledger bolted to the house is the most common point of deck failure, which is why departments inspect the footings, framing and ledger connection before the decking goes on. Adding a roof makes the deck a covered structure that is reviewed like a patio cover or addition, including roof framing and, in high wind areas, uplift connections.
