Where Can You Legally Put a Real Estate Sign in Seminole County?

Updated September 2026 · Reviewed by Adams, Cameron & Co.

Why this is genuinely harder in Seminole County than most markets

Nobody covers this in pre-licensing, and most agents learn it when a code enforcement officer has already pulled a sign out of the ground.

Two separate rules govern a real estate sign. What must be printed on it is a state rule and it is identical everywhere in Florida. Where you may put it is a local rule, and in Seminole County there are eight separate sets of them: the county's own code for unincorporated areas, plus 7 incorporated cities, each with its own sign ordinance.

That is a lot of boundaries for a county this compact. An agent working Longwood, Oviedo, Sanford, Lake Mary in a single week is crossing four ordinances, and the rules genuinely differ at the line.

The rule that is the same everywhere: stay out of the right-of-way

The public right-of-way is the strip of land along a road that belongs to the government rather than to the homeowner. It usually extends several feet past the edge of the pavement, often past the sidewalk, and frequently includes the grassy strip a homeowner mows and reasonably assumes is theirs. It is not theirs, and it is not yours to put a sign in.

Every jurisdiction in this county prohibits signs in the public right-of-way in some form. What varies is what happens next, and in Florida the common answer is that the sign is simply removed, frequently with no notice step written into the code at all. You do not get a warning; you get an empty post hole.

The practical test on a listing is simple. If you are unsure where the line is, set the sign well inside the property, closer to the house than feels necessary. A sign two feet too far back still gets seen. A sign two feet too far forward gets taken.

Do not attach a sign to a pole, a tree, or a fence

This is close to universal across Florida codes and it is the rule most often broken by open house directional signs on a Sunday afternoon.

Utility poles deserve a specific warning, because dismissing this as bureaucratic is a mistake. A utility pole is not public infrastructure for your convenience. It belongs to a utility, it is climbed by line workers, and a staple or nail left behind is a genuine hazard to someone whose job involves putting a hand where your sign used to be. Traffic control devices are worse again, because obscuring or adding to one creates a safety problem rather than an aesthetic one.

The HOA layer, and the Florida fact that surprises people

A city sign code sets the outer boundary. Inside a deed-restricted community the recorded covenants can be stricter, and in Florida they are allowed to be a great deal stricter.

Some states protect a homeowner's right to advertise their own property for sale. Florida does not. The Florida Homeowners' Association Act addresses signs in one narrow place: under F.S. 720.304(6), a parcel owner may display a sign of reasonable size provided by a contractor for security services within ten feet of an entrance to the home. That is the protection, and it covers the alarm company sign by the front door. There is no companion provision protecting a for sale sign.

Where an association's recorded governing documents restrict or prohibit for sale signs, that restriction generally stands. A seller who assumes a sign is their right is assuming something the statute does not say, and this matters more in Seminole than in most places: Lake Mary, Oviedo and Winter Springs carry a high proportion of master-planned, association-governed communities, which is exactly where this comes up.

Read the governing documents before the listing appointment, not after the sign goes in the ground.

Which jurisdiction is your listing actually in?

Worth stating because it is the question that decides everything above, and it is not always obvious from a mailing address. A property with a Sanford or Oviedo postal address may sit in unincorporated Seminole County and be governed by the county's code rather than the city's.

The eight sets of rules in play here:

• unincorporated Seminole County
• Sanford
• Lake Mary
• Longwood
• Oviedo
• Winter Springs
• Altamonte Springs
• Casselberry

How many working agents sit in each, counted from the state license file on September 22, 2026, which is a fair proxy for how often each set of rules comes up in practice:

• Longwood: 931 active licensees
• Oviedo: 853 active licensees
• Sanford: 800 active licensees
• Lake Mary: 746 active licensees
• Altamonte Springs: 606 active licensees
• Winter Springs: 570 active licensees
• Casselberry: 314 active licensees
• Unincorporated Seminole County and smaller places: the balance of the county's 4,254 active licensees

Longwood, Oviedo, Sanford and Lake Mary between them account for 3,330 of those licensees, so four of the eight rule sets cover most of the working agents here. If you are going to research only some of them, research those.

Check the parcel against the county property appraiser record rather than the mailing address. It takes a minute and it is the difference between the right rule and a plausible guess.

Where to get the current figures for your city

Now the honest part, because you are entitled to know what this page does and does not tell you.

This page does not give you the permitted sign dimensions, setbacks or time limits for each of those eight jurisdictions. Those numbers exist, they differ meaningfully between cities, and they are amended often enough that a figure published here would be reliable for an unpredictable length of time. Publishing a number that is wrong by the time you read it would be worse than publishing none, because you would act on it.

Two places will give you the current answer:

1. The Governmental Affairs Department at your REALTOR association. For Seminole County that is the Orlando Regional REALTOR Association, which maintains sign ordinance guidance for the jurisdictions it covers and exists precisely to answer this. This is the fastest route and it is included in what your dues already pay for.
2. The city or county planning and development services department directly. Slower, and definitive. Worth doing once for the two or three jurisdictions you actually work, and writing the answers down.

Ask four things each time: maximum sign area, how far the sign must sit back from the right-of-way, whether a permit is required, and how soon after closing the sign must come down. Those four answers cover almost every situation you will meet.

What this means for how you work a listing

Build it into your process rather than treating it as something to remember. Three habits cover it.

Confirm the jurisdiction when you take the listing, from the parcel record rather than the address, and note it in the file alongside the association status. Keep a one-page note of the four answers for each jurisdiction you work, because you will work the same three or four repeatedly and the research is a one-time cost. And treat open house directional signs as the higher-risk category, because they sit on corners and verges you do not control, on a Sunday when nobody is answering a phone at the city.

None of this is difficult. It is simply not taught, and the cost of getting it wrong lands on the licensee rather than on the brokerage.

Where Adams, Cameron & Co. fits

Stated plainly, because it saves your time: all nine of our locations are in Volusia and Flagler counties, and we have been a brokerage on that coast since 1963. We do not have an office in Seminole County. The nearest is our West Volusia office in DeLand, roughly 22 road miles from Sanford and further from the south of the county.

What is not a problem is the MLS. That office sits in the West Volusia Association of REALTORS, which uses Stellar MLS, the same system Seminole agents use, so an agent working out of it is not cut off from Seminole inventory.

We publish this page because knowing a market at this level of detail is the job rather than a flourish on top of it. Use it whether or not the drive works for you.
