Who Actually Decides What You Can Do to Your Home: The Five Authorities Explained
The same confusion turns up across nearly every question a household asks about a long-owned property. Someone gets a favorable answer from one office and assumes it settles the matter, only to discover a second, entirely separate authority governs the part they actually needed answered. This is not a failure of research. It is that five distinct bodies can each hold jurisdiction over a single Palm Beach County parcel, and a favorable answer from one is not an answer from any of the rest.
This piece exists because that confusion is expensive to resolve after the fact and inexpensive to resolve before it. It sits alongside our five housing paths framework as a reference for any of the five paths that touches what a property is permitted to do.
The Five Authorities, and What Each One Actually Decides
The Five Authorities
- The Palm Beach County Property Appraiser. Administers assessed value, exemptions, and portability. Does not hold permit authority, does not determine what may be built, and does not set millage rates. It's common for someone to know the Property Appraiser and stop there, when the actual question belongs to one of the other four.
- The building authority with jurisdiction. Issues permits and determines what may be built, from a code standpoint. Which authority that is depends on the parcel — the municipality where a property sits inside city limits, or Palm Beach County's building function where it sits in unincorporated territory. This is not always obvious from the address alone: in Boca Raton, the City notes on its own site that a Boca Raton address does not necessarily place a property inside its limits.
- The zoning function. A distinct process from permitting, usually housed within the same municipality or county, that determines setbacks, lot coverage, height limits, and whether a given use is permitted in that district at all. A structurally straightforward project can fail here on a setback, which is why the zoning question belongs before design work begins, not after.
- An association's architectural review, where one exists. A separate approval with its own standards, its own submission requirements, and its own calendar. It does not run on the building department's schedule, and board meeting cycles do not adjust to an owner's timeline. The governing documents set the actual standards and are available to owners.
- Overlay and historic review, where it applies. Layered on top of the other four for some parcels and not others. In Delray Beach, properties inside one of the locally designated historic districts require a Certificate of Appropriateness for exterior alterations, additions, and demolition, while interior work and general maintenance typically remain at the owner's discretion. In Wellington, the Equestrian Preserve Area is a land-use overlay governing what may be built on parcels within it. In Juno Beach and along the coast, a property's position relative to the state's Coastal Construction Control Line can affect what's permitted, including beachfront lighting requirements. In West Palm Beach, jurisdiction, historic designation, zoning overlay, and airport noise mapping can each apply to a single address independently of the others.
None of the five answers for any of the others. A favorable zoning determination is not an association approval. An association approval is not a permit. And nothing on this list determines assessed value or tax treatment — that stays entirely with the Property Appraiser.
Do you know which of the five apply to your specific parcel?
Most owners can name the Property Appraiser and stop there. Establishing the other four is a records exercise, answerable in a handful of phone calls rather than a set of drawings.
Why This Gets Compressed So Easily
What we've seen repeatedly is that the five authorities get collapsed into one another: whichever office someone reaches first gets treated as though it speaks for the rest. A call to the Property Appraiser about assessed value gets remembered as "I checked, and it's fine" for a question that was actually about permitted use. A neighbor's account of what the association allows gets treated as a substitute for the governing documents.
The order in which these get checked matters as much as checking them at all. Zoning and jurisdiction belong before a contractor's estimate, not after — a project that turns out to conflict with a setback or an overlay is money spent to learn something a phone call would have established. Association review belongs before a submission deadline is a surprise. Historic and overlay review belongs before exterior work is scheduled, since a Certificate of Appropriateness process has its own timeline entirely separate from a building permit's.
Frequently Asked Questions
How do I find out which of the five actually apply to my property?
Start with jurisdiction: confirm whether the parcel sits inside a municipality or in unincorporated Palm Beach County, since that determines which building authority and which zoning function have jurisdiction. From there, check whether an association exists and request its governing documents, and ask the relevant municipality or county directly whether the parcel sits within any historic district or overlay. Each of these is a records question rather than an inspection, and each office is the correct source for its own answer.
If I get approval from one of the five, does that mean the project is cleared?
Not necessarily. Each authority answers only its own question. A property could clear zoning and still require association architectural review, or clear a building permit and still fall inside a historic district requiring separate approval for exterior work. The only way to know a project is fully cleared is to establish which of the five apply and confirm each one separately.
Who do I ask if I'm not sure which authority governs a specific question?
A real estate advisor can generally help identify which of the five a given question belongs to and point you toward the right office, without answering the substantive question themselves — that stays with the authority that actually holds it. Where a governing document is ambiguous or the stakes are significant, an attorney is the appropriate professional to interpret it.
In our experience, this confusion is usually caught only once a project is already underway, when correcting course costs real time and money. The five authorities are establishable in advance, and doing so changes very little about what a property can do — it only changes when you find out. If you'd like help identifying which apply to your specific parcel, a practical conversation is a reasonable place to begin.
