Real Estate Abbreviations and Listing Jargon Decoded for South Florida Buyers and Sellers

Real estate abbreviations fill South Florida listings, and many of them mean little to someone new to the area. A listing might say "3/2 CBS, FROG, impact glass, 2,100 SF under air, no HOA." To a local agent, that is a clear picture of the house. To a buyer from out of state, or a seller writing their own description, it can read like code. This guide decodes the terms you will see most in Palm Beach County, groups them by topic, and explains why each one can affect price, insurance or your offer.

Key takeaways

• CBS means concrete block and stucco construction. It is common across South Florida and matters for insurance and buyer appeal.
• Under air means air-conditioned living area. Property appraisers often report a different, larger "adjusted" area, so the two numbers rarely match.
• A bath count of 2.1 means two full baths and one half bath. Appraisers count a three-quarter bath as full.
• An estoppel certificate shows what a seller owes the HOA. Florida law requires the association to deliver it within 10 business days of a request.
• A CDD can add a yearly assessment on top of property taxes. Florida requires a bold disclosure in contracts for the first sale of a home in a district.

Why real estate abbreviations matter

Listings have limited space. Agents use short codes to fit key facts into a few lines. However, those codes carry real weight. A term like "CBS" or "impact glass" can change what a buyer pays for insurance. Likewise, a phrase like "estoppel" or "CDD" points to costs that do not show up in the list price.

For sellers, the right terms help buyers find your home in searches and filters. For buyers, knowing the codes helps you sort listings faster and ask better questions. So it pays to learn the main ones before you start touring.

Real estate abbreviations for size and layout

BR, BA, 3/2 and 2.1: BR means bedroom and BA means bathroom. Florida listings often write a home as "3/2," which means three bedrooms and two baths. You may also see bath counts like 2.1. In that format, the number before the period counts full baths and the number after it counts half baths.

Appraisers follow a similar rule. Under Fannie Mae's Uniform Appraisal Dataset, a three-quarter bath counts as a full bath, and a room with only a toilet is not counted. So a listing with an extra toilet room may still show the same bath count as a home without one.

Square footage terms: SF, under air and FROG

SF, sq ft and under air

SF and sq ft both mean square feet. In South Florida, though, you will often see "under air." That means the air-conditioned living area. It leaves out garages, open patios and screened porches.

This is where buyers get confused. Property appraiser records may show an adjusted or total area that includes garages, patios and covered entries at a fractional rate. The Broward County Property Appraiser explains that its adjusted figure can be higher or lower than the living area in MLS listings. So when two numbers differ, ask which one each source is using.

FROG: FROG stands for finished room over garage. It is often used as a bonus room, office or guest space. When you see it, ask whether the room is cooled by the main system and whether it counts toward the under air figure. Also ask whether it was permitted as living space.

Real estate abbreviations for construction and storms

CBS: CBS means concrete block and stucco. The outside walls are concrete block covered with stucco. Many buyers and insurers like CBS homes in hurricane country. By contrast, a "frame" home uses wood framing for its outer walls.

Impact glass, IW and hurricane shutters: Impact glass, sometimes written as impact windows or IW, is glass built to resist windborne debris. Shutters are a separate form of protection that covers openings before a storm. Both can matter for the wind mitigation form that insurers use to set discounts. So when a listing says "full impact," ask for the product approvals and the permit records.

NOA and roof age: NOA means Notice of Acceptance, a Miami-Dade product approval. You may see it on window and roof listings. Roof age also shows up often in remarks, such as "2021 roof." Buyers care because roof age affects insurance. Under Florida Statutes section 627.7011, an insurer may not refuse to write or renew a policy solely because a roof is less than 15 years old.

HOA and community real estate abbreviations

HOA, POA and COA: HOA is a homeowners association. POA is a property owners association, which works in a similar way. COA means condo owners association. Each can set rules and collect fees. Our guide to how HOAs work in Florida covers the basics.

Estoppel or estoppel certificate: An estoppel certificate is a statement from the association that shows what the seller owes in dues, assessments and fees. Title companies order it before closing. Under Florida Statutes section 720.30851, an HOA must issue it within 10 business days of a request. The statute also caps the fee, starting at $250 for an account in good standing, with set extras for rush service or delinquent accounts. Those caps adjust for inflation every five years.

CDD: CDD stands for community development district. It is a special district that can fund roads, water systems and other public works in newer communities. Under Florida Statutes section 190.048, contracts for the first sale of a home in a CDD must carry a bold disclosure. It warns that the district may levy taxes or assessments on top of county taxes. So always ask how much the yearly CDD charge is.

HOPA and 55+: HOPA refers to the federal Housing for Older Persons Act. A "55+" community uses this exemption to limit sales to older buyers. Under federal rules, at least 80% of occupied units must have at least one resident who is 55 or older.

Real estate abbreviations about status and sale type

DOM and CDOM: DOM means days on market. CDOM, or cumulative days on market, adds time from earlier listings of the same home. A high CDOM can hint that a home was relisted to reset the clock.

For context, in August 2026 Palm Beach County single-family homes took a median of 40 days to go under contract, according to Miami Realtors. Condos and townhouses took 69 days. So a house with far more time than that may have room to negotiate.

REO and SS: REO means real estate owned, a home that a lender took back through foreclosure. SS means short sale, where the lender agrees to accept less than the loan balance. Both can bring longer timelines and extra paperwork.

As is: "As is" means the seller does not plan to make repairs. In Florida, many sales use an "AS IS" contract form. Buyers can usually still inspect and may be able to cancel during the inspection period. Read the contract terms with your agent.

Water and location real estate abbreviations

Water access is a big deal here, so listings use short codes for it.

• WF: waterfront. Ask whether the water is a canal, lake, river or the Intracoastal.
• ICW: Intracoastal Waterway, the inland water route that runs along the coast.
• Ocean access: a canal that connects to the ocean, usually through an inlet. Bridge heights may limit boat size.
• East of 95 or east of US 1: a location cue that suggests the home is closer to the coast.

Buyers searching in West Palm Beach or Boca Raton will see these codes often. Ask your agent to confirm water access and any flood zone before you write an offer.

Marketing phrases to read between the lines

Some listing words are not abbreviations, but they still carry a hidden message.

• Priced to sell: usually the seller wants a fast sale. Compare it to recent sales anyway.
• Cozy: often means small.
• Bring your ideas or TLC: expect updates or repairs.
• Motivated seller: the seller may accept terms or a price below asking.
• Highest and best: the seller has more than one offer and wants final bids by a deadline.

Sellers should use these phrases with care. A vague term in the remarks can attract the wrong buyers. Clear facts, such as roof year, impact glass and under air size, usually work better.

Frequently asked questions

What does FROG mean in a Florida listing?

It means finished room over garage. Ask whether it is cooled, permitted and included in the living area figure.

Why is under air smaller than the property appraiser's figure?

Under air counts only cooled living space. Appraiser records may include garages and patios at partial rates, so their total is often larger.

What does 2.1 baths mean?

It means two full baths and one half bath. A half bath usually has a toilet and sink but no tub or shower.

Which real estate abbreviations affect insurance most?

CBS, impact glass, NOA and roof age matter most. Each one ties to the wind mitigation form or to roof rules insurers use.

Are CDD fees the same as HOA fees?

No. A CDD is a special district that levies taxes or assessments, often on the property tax bill. HOA dues are set by the association and paid to it.
