Garage Sale Signs That Actually Bring Cars (San Antonio Rules Included)

Shoppers can't buy from a sale they never find. Online listings do the planning, but signs do the last half-mile — they catch the neighbor two streets over, the driver who took a wrong turn, the passerby who didn't know today was sale day. A good sign chain turns a quiet street into a steady stream of cars. A bad one — tiny letters, no arrow, illegal placement — gets ignored or removed. Here's how to do signs right in San Antonio, rules included.

Design: readable at 30 miles per hour

Your reader is a driver with about two seconds of attention. Design for that reader:

• Few words, huge letters. "GARAGE SALE" plus an arrow, your street number, and the hours. That's the whole message — everything else is decoration the driver will never read.
• Contrast beats color. Black marker on white or neon poster board reads from a moving car. Thin pens, light colors, and glitter gel pens do not.
• The arrow is the product. A sign without a clear, bold arrow is an advertisement, not a direction. Every sign in your chain needs one, pointing the correct way — double-check from a driver's seat, not the sidewalk.
• Same look, every sign. Same colors, same lettering. Drivers follow a trail they recognize from corner to corner.
• Sturdy and weatherproof. Corrugated plastic or foam board on a stake survives a San Antonio morning; a paper flyer in plastic wrap does not survive the humidity.

Placement: build a breadcrumb trail

Think like the driver. Put your first sign where traffic already flows — the entrance to your neighborhood or the nearest busy corner (placed legally, see below) — then a sign at every turn between there and your driveway. Miss one turn and your trail dies. Finish with the sign at the sale itself, and park a car with balloons or a bright marker near the curb if your street looks like every other street. Then, the step everyone forgets: drive your own route before the sale opens. If you can't follow your signs at speed, neither can your shoppers.

The San Antonio sign rules (from the city)

Signs aren't a free-for-all inside city limits — they come with your garage sale permit, and the rules are specific. As laid out in our San Antonio garage sale permit guide:

• Three signs, total. One goes at the sale itself; the other two can go off-premise to guide drivers in.
• 6 square feet maximum per sign — big enough for bold letters, small enough to stay legal.
• Off-premise signs must carry the sign decals that come with your permit. Off-premise signs without decals placed in the public right-of-way can be removed and discarded without notice.
• Never on poles. Don't tape or attach a sign to a utility pole, street sign, traffic sign, or light pole — the city treats that as a misdemeanor.
• Timing: signs can go up two days before your sale, and they all come down when the permit expires. Take them down on time — leftover signs are how neighborhoods (and code officers) learn to dislike garage sales.

Signs bring the neighborhood. Listings bring the city.

Signs only reach people already driving near you. The hunters planning Saturday routes across San Antonio are online — checking the weekend map and the Deal Board to decide which sales make the trip. Post your sale there too, with photos of the good stuff, and your signs become the final turn-by-turn for shoppers already on their way. One more courtesy that pays off: when you take your signs down Sunday, do a quick loop for any strays — a clean neighborhood is a neighborhood that welcomes your next sale.
