Quick answer: A home theater is a separate room built for watching, which the trade association CEDIA describes as a "Dedicated, darkened room" with "Fixed seating and large screen or projector," while a media room is "Part of your existing living space" with "Flexible seating and layout." CEDIA and CTA's immersive audio recommended practice, CEDIA/CTA-RP22 (version 1.2, September 2023), sets those names aside when it defines performance and rates a room from Level 1 to Level 4, so the label tells you less than the room does. The national MLS standard, the RESO Data Dictionary (version 2.0, as of October 24, 2026), has a "Media Room" room type and no "Theater" value, so a listing that says theater is using words outside the national standard, which may come from the listing agent or a local MLS label. In the Florida Realtors/Florida Bar AS IS contract (form ASIS-7x), "television wall mount(s) and television mounting hardware" are on the list of included items if the seller owns them and they are not excluded, but televisions, projectors, speakers and theater seating are not named, so write each one into the contract.
A listing can call a room a home theater, a theater room or a media room. Only one of those names is in the national MLS standard, and the industry's audio standard uses none of them to rate a room.
What is the difference between a home theater and a media room?
CEDIA, a trade association, puts the two side by side on its homeowner page (undated, viewed October 24, 2026). These are its words, lightly trimmed, arranged in a table:
| Home theater (CEDIA's heading: "Smart Home Theaters") | Media room | |
|---|---|---|
| The room | "Dedicated, darkened room" | "Part of your existing living space" |
| Seating and screen | "Fixed seating and large screen or projector" | "Flexible seating and layout" |
| Purpose | "Designed to feel like a movie theatre," for when "film and TV are your main focus" | TV, sport, music and gaming, in "smaller spaces and mixed use" |
The same page adds that "Home cinemas often lack windows and have fixed seating." Put plainly, a home theater is a room that does one job, and a media room is a living space that also does that job.
Does the industry standard rank a theater above a media room?
No. CEDIA and CTA publish CEDIA/CTA-RP22, the "Immersive Audio Design Recommended Practice," version 1.2, dated September 2023. Section 3.2.2 says that "For the purposes of defining performance, definitions such as dedicated/home/private cinema/theater, or media room" "are removed," and the document says a multi-use space can still reach the higher levels. It rates the room instead:
| RP22 level | What Section 3.2 says |
|---|---|
| Level 1 | "The minimum level of performance necessary to convey basic artistic intent." |
| Level 2 | "A higher level of performance that more accurately conveys artistic intent." |
| Level 3 | "Meets or exceeds reference commercial cinema exhibition standards." |
| Level 4 | "The maximum level of achievable performance across every parameter." |
The level has to hold at "the reference seating position" and "at least one adjacent seating position." ANSI's blog, in a post dated September 28, 2026, refers to CEDIA-CTA-RP22-2023 as "this American National Standard" and says it does not cover how to measure or verify a finished system's performance. If a listing claims an RP22 level, ask who designed the room and what documents back that up.
What should I look at during a showing?
| What you see | What the sources say | What to ask |
|---|---|---|
| Rows of fixed seats on steps | CEDIA's FAQ lists "tiered seating for multiple rows"; RP22 lists seat risers "to ensure head clearance" among layout constraints | Whether the seats and riser stay |
| A projector and screen | CEDIA's FAQ ties projectors to dark rooms and TVs to well-lit rooms, yet its homeowner page says "Media rooms work better with projectors" | Whether the projector, screen and mount stay |
| Speakers in the ceiling | Overhead speakers are the last number in a layout such as 7.1.4 (see below) | The installer's speaker plan |
| Panels on walls and ceiling | CEDIA's FAQ: acoustic panels "absorb sound reflections"; RP22's goal is that outside noise "should not be audible from within" | Close the door and listen |
| An equipment rack | The preview of CEA/CEDIA-CEB24, "Home Theater HVAC" (June 2012), says HVAC should be sized for "the added heat load generated by people and AV equipment" (RP22 cites CTA/CEDIA-CEB24-A, which may be a later revision; I did not read it) | How the rack is cooled |
What does 7.1.4 mean?
Dolby's guide, the Dolby Atmos Home Theater Installation Guidelines (December 2018), explains the last number: in a layout such as 5.1.4, "the .4 indicates the four speakers that play overhead sound." So a 7.1.4 room has four overhead speakers. RP22 says Dolby recommends layouts from 3.1.2 up to 24.1.10, with 5.1.4 and 7.1.4 the most common. The same Dolby guide says, "Installing all of the speakers in the ceiling will not give the optimal experience and is not recommended." I am citing Dolby only for what the last number means and for that one placement note; for the rest of a layout, ask for the installer's plan.
How far should the seats be from the screen?
CEDIA's FAQ puts seating at "typically 1.5 to 2.5 times the screen diagonal." For a screen with a 100-inch diagonal, that is 150 to 250 inches, or 12.5 to about 21 feet. RP22 says the main seat "should ideally be on the perpendicular axis of the front center speaker," "Avoid aisles in the middle of the room," and strongly recommends against a row of seats or a sofa against the back wall. No source I used gives a riser height, so I do not give one.
How does the MLS label a home theater or media room?
The RESO Data Dictionary sets the standard field names that MLS systems map to. As of October 24, 2026, its version 2.0 RoomType list has 33 values, including "Media Room": "A room that is specifically geared for the watching of movies, TV or other forms of multimedia." It has no "Theater" or "Home Theater" value; related values are "Game Room," "Bonus Room," "Family Room" and "Den."
The interior features list has "Sound System," a system that "typically includes in-wall wiring and recessed/built-in speakers and a built-in location for the amplifier," and "Wired for Sound," which says, "The wiring is in place, but equipment may not be included." It has no theater, media, soundproof or surround value, so a theater may show up only in the remarks. I did not check the field list of the local MLS behind any given listing, so I read the remarks and confirm the room in person.
Does the TV, projector or theater seating stay with the house?
What stays is set by the signed contract, and I have not found a source saying an MLS entry changes it. The Florida Realtors/Florida Bar AS IS Residential Contract for Sale and Purchase, form ASIS-7x, in the version Florida Realtors posted in February 2026, handles it in three parts of paragraph 1:
| Paragraph | What it says | For a theater |
|---|---|---|
| 1(c) Real Property | "all existing improvements and fixtures, including built-in appliances, built-in furnishings and attached wall-to-wall carpeting and flooring" | The form does not define "fixture" or "built-in," so it does not settle in-wall speakers or a fixed riser |
| 1(d) Personal Property | A list that includes "television wall mount(s) and television mounting hardware," then "Other Personal Property items included in this purchase are:" | The mount is named; the TV, projector, screen, speakers, receiver, amplifiers, rack and seating are not |
| 1(e) | "The following items are excluded from the purchase:" | Where a seller lists anything leaving with them |
The TV mount wording dates from 2021: Florida Realtors said on September 7, 2021 that "Personal Property" "now includes thermostats, doorbells, television wall mounts and television mounting hardware," effective "Nov. 1, 2021." The list applies "Unless excluded in Paragraph 1(e) or by other terms of this Contract," and only to items "owned by Seller and existing on the Property as of the date of the initial offer," and the walk-through lets the buyer confirm "that all items of Personal Property are on the Property."
So name each piece of equipment, with brand and model where you can, on the 1(d) line or in 1(e), and ask a Florida real estate attorney about any disputed item. My post on what happens when a home fails inspection under the as-is contract covers more of the form.
Will a Florida home inspection test the theater system?
Not necessarily. Under Rule 61-30.803, F.A.C., the standard of practice for electrical systems, the inspector is not required to inspect "Remote control devices" or "Low voltage wiring, systems and components, ancillary wiring and systems and components" "not a part of the primary electrical power distribution system." Under Rule 61-30.807(4), the inspector is not required to "Operate any system, appliance or feature that requires the use of special codes, keys, combinations, or devices." A theater run from a remote, keypad or app can fall under both. Ask the seller to run the system at a showing, and ask your inspector in writing what they will check.
Does home theater work need a permit?
The permit pages I read show categories, not a rule. The City of Port St. Lucie's Residential Permit Fee Schedule (effective May 2, 2022, updated July 30, 2025) has a "Low Voltage" line, and Martin County's Building Permit Application (Rev. 7-26) lists "Low voltage" among "Additional work to be done under this permit." Neither says which home audio and video work needs a permit, so ask the building department, and ask the seller for permit records for added circuits, wiring or construction. My post on what Florida sellers must disclose covers the seller's side.
NEMA's code alert says the 8th Edition (2023) Florida Building Code took effect December 31, 2023 and "includes adoption of the 2020 NEC, with no state amendments." As of October 24, 2026, the Florida Building Commission's October 2026 workplan lists December 31, 2026 as the effective date of the 9th Edition (2026), so ask the building department which edition applied when the work was permitted. I did not read the NEC and found no code text on dedicated circuits for theater equipment, so that is a question for a licensed electrician.
What does the CPSC say about securing TVs?
For any TV that sits on a stand or furniture in a media room, the Consumer Product Safety Commission (CPSC), in a February 5, 2026 release, said to "Anchor TVs and furniture like bookcases and dresser securely to the wall," and reported, "From 2013 to mid-2023, 217 tip-over fatalities were reported; 71% of those killed were children ages one to three years." For a TV on a wall mount, ask who installed the mount and what it is fastened to; whether the mount stays turns on the 1(d) conditions above.
How do I confirm a home theater at a showing?
- Is it a separate, darkened room with a door, and does it have windows?
- Are the seats fixed and in rows on risers, and is a row against the back wall?
- How many speakers are overhead? Ask for the layout, such as 7.1.4.
- With the door closed, can you hear the rest of the house?
- Where is the equipment, and how is it cooled?
- Who designed and installed it, to what RP22 level if any, and what permits were pulled?
- Which equipment, remotes and logins stay? Write them into 1(d), and anything leaving into 1(e).
Selling? Decide what stays before you list, and describe it the same way in the listing and the contract.

Questions people ask about home theaters and media rooms
What is the difference between a home theater and a media room?
CEDIA describes a home theater as a "Dedicated, darkened room" with "Fixed seating and large screen or projector," and a media room as "Part of your existing living space" with "Flexible seating and layout." The CEDIA/CTA-RP22 standard (version 1.2, September 2023) drops both labels when it defines performance and rates rooms Level 1 to Level 4 instead.
How is a home theater listed in the MLS?
As of October 24, 2026, the RESO Data Dictionary has a "Media Room" room type and no "Theater" or "Home Theater" value. Related feature values are "Sound System" and "Wired for Sound," so a theater may appear only in the listing's remarks.
What does Wired for Sound mean in a listing?
The RESO Data Dictionary, as of October 24, 2026, defines it as a property that "has been wired for a built-in sound system" and says "The wiring is in place, but equipment may not be included." Ask which speakers and electronics stay, and write them into the contract.
Does the TV stay with the house in Florida?
The ASIS-7x contract includes "television wall mount(s) and television mounting hardware" in paragraph 1(d), if the seller owns them and they are not excluded, but does not name televisions, projectors, speakers or seating. Write each item into the 1(d) line for other included items, or exclude it in 1(e).
What does 7.1.4 mean?
Dolby's December 2018 installation guidelines say that in a layout such as 5.1.4, "the .4 indicates the four speakers that play overhead sound." A 7.1.4 room has four overhead speakers.
Will my home inspector test the theater system?
Not necessarily. Florida's Rule 61-30.803 says inspectors are not required to inspect remote control devices or low voltage systems that are not part of the primary electrical power distribution system, so ask the seller to run the system and ask your inspector in writing what they will check.

Call or text (772) 800-2274 or send a message.
General information, not legal, tax, engineering, electrical, medical, lending or insurance advice, and not a guarantee of any price, fee, feature or outcome. RP22 levels describe performance, and, per ANSI, the standard does not cover verifying a finished room; I did not confirm which residential audio and video work needs a permit in any Treasure Coast or Palm Beach County jurisdiction, and the contract does not say whether in-wall speakers or seat risers are fixtures. Confirm permits with the building department, wiring with a licensed electrician and contract terms with a Florida real estate attorney. References are as reviewed on October 24, 2026.
