San Antonio Fire Lane Marking Requirements for Property Owners

If you own or manage a commercial property in San Antonio, the city's fire code decides how your fire lanes are marked. The short version is that San Antonio requires fire lane signs, and fire lane curbs are painted red with white "Fire Lane, No Parking" lettering 4 inches tall, spaced no more than 40 feet apart.

The rest of this post walks through what the code says, how the rules change outside San Antonio city limits, and how often fire lanes need to be repainted. We stripe fire lanes for a living and don't practice law, so treat this as a plain-English guide and confirm anything specific to your property with the Fire Marshal.

Who Decides Where Your Fire Lanes Go

In San Antonio, the Fire Marshal designates fire lanes. On new construction, the fire lanes are drawn on the fire protection site plan, and that plan has to be approved before a building permit is issued.

Once a fire lane is designated, the Fire Marshal notifies the owner, and from then on marking it and keeping it clear is the owner's job. That is why fire lane work almost always lands on the property manager's desk instead of the city's.

What San Antonio's Fire Code Requires

San Antonio adopts the International Fire Code with its own local amendments, and its version of section 503.3 spells out how fire lanes are marked. You can read the full text in the city's 2024 fire code amendments, but here is what it means for your property:

• Signs are required. Once a fire lane is designated, the owner posts signs that read "Fire Lane - No Parking at any Time City Ord. 54547."
• Red curbs. Owners can choose to paint fire lane curbs red, and the Fire Marshal can also require it.
• White lettering. Red curbs are stenciled in white with "Fire Lane, No Parking" in 4-inch letters, with no more than 40 feet between each set of wording.
• Red stripes where needed. If a fire lane isn't clearly defined, the Fire Marshal can require a 4-inch red stripe that marks its edges.

Once the signs are up or the red curbs are painted, it is unlawful for anyone but an emergency vehicle to park in the fire lane. The code also allows property owners to have vehicles towed from a fire lane. Both of those only work if drivers can actually see the markings, which is why the paint matters as much as the signs.

Fire Lane Rules Outside San Antonio

Every city around San Antonio adopts its own fire code, so the wording, letter size, and spacing can change as soon as you cross a city line. Live Oak's fire code, for example, has called for 4-inch white lettering every 25 feet, along with paint on both the face and the top of the curb.

If no local rule applies, Texas law sets a default. Under Texas Occupations Code section 2308.251, fire lane curbs are painted red and marked "FIRE LANE TOW AWAY ZONE" in white letters at least 3 inches tall. Those markings go no more than 50 feet apart, but a city's own fire lane rule takes priority wherever it has one.

If your property is in New Braunfels, Schertz, Boerne, Converse, or another city around San Antonio, confirm the standard with that city's fire marshal before any paint goes down. We do that as part of every fire lane striping job outside San Antonio.

How Often Fire Lanes Need to Be Repainted

None of the fire codes we work with set a fixed schedule for repainting. The model fire code says fire lane markings have to stay clean and legible; in practice, that means you repaint them whenever they start to fade.

In San Antonio's sun, solvent-based paint usually lasts around 2 to 3 years, so most properties repaint their fire lanes with every restripe. If your red curbs have faded to pink, repainting them before an inspection is quite a bit easier than repainting them after one. Our post on how often to restripe a parking lot covers the other signs to watch for.

What It Costs to Repaint a Fire Lane

Fire lane curbs are priced by the linear foot, up to $1.20 per linear foot, because the paint has to cover both the top and the face of the curb. If your property has 200 feet of fire lane curb, that's up to $240 for the curb paint.

Stencils, pavement stripes, and signs are listed separately on the quote, so you can see what each part costs. Our post on parking lot striping costs explains how the rest of a striping quote comes together.
