MLS Public Remarks Character Limit: What Every Listing Agent Needs to Know

The MLS public remarks character limit varies by MLS system, but most platforms set a ceiling between 500 and 1,000 characters for the public-facing remarks field — the section that syndicates directly to Zillow, Realtor.com, and broker websites. Knowing your local limit is only half the job; the other half is understanding what content is and isn't permitted in those characters, because violations can get your listing flagged or pulled.

Key Takeaways

• The MLS public remarks character limit varies by board, typically ranging from 500 to 1,000 characters, so always check your specific MLS before drafting copy.
• Public remarks are visible to consumers on third-party sites like Zillow and broker websites, which is why content rules are strictly enforced.
• Agent names, phone numbers, website URLs, lender references, and agent incentives are prohibited in public remarks — seller-to-buyer incentives are allowed.
• The builder's company name may appear in public remarks, but promotional language beyond naming the builder is not permitted.
• Use every available character to describe the physical property and its surroundings — that is the intended and compliant purpose of the field.

Why the MLS Public Remarks Character Limit Matters More Than You Think

Public remarks are not just an internal data field — they are viewable by the public on third-party and broker websites [1]. That means every word you write in that field is consumer-facing copy the moment you hit submit. The character limit exists partly for data-formatting reasons across syndication platforms, but the content rules exist because the MLS is designed to be a professional resource of objective property information, not a marketing channel for individual agents or vendors [7].

When you treat the character limit as a nuisance, you end up cramming in the wrong things — agent taglines, website URLs, lender shoutouts — and leaving out the property details buyers actually need. Flip that mindset: treat the character ceiling as a discipline tool that forces you to prioritize the most compelling, compliant property details. A tight 700-character description built around the home's best physical features will outperform a bloated 1,000-character block stuffed with prohibited content every single time.

How the MLS Public Remarks Character Limit Varies by Platform

There is no universal MLS public remarks character limit. Each MLS board sets its own ceiling, and those numbers differ meaningfully across the country. Most systems land somewhere between 500 and 1,000 characters for the public remarks field specifically — separate from private agent remarks, which have their own limits and their own rules.

Because this post covers general MLS compliance principles rather than one specific board, you need to pull up your MLS's current field specifications before you draft a single word. Log into your MLS back end, navigate to the listing input form, and look for the character counter on the public remarks field. Most modern MLS platforms display a live character count as you type. If yours doesn't, paste your draft into a free word counter tool to check length before submission.

A few practical benchmarks agents ask about: Zillow displays the full remarks field as syndicated from the MLS, so whatever character limit your MLS enforces is effectively your Zillow limit too — there is no separate Zillow character limit to optimize for independently. Write for your MLS, and the syndication takes care of itself.

What Is and Isn't Permitted in Public Remarks

This is where agents get into trouble. The content rules for public remarks are specific, and ignorance of them doesn't protect you from a compliance flag. Here is a plain breakdown based on MLS guidelines:

Public remarks cannot contain agent names, phone numbers, or anything that promotes the listing agent or firm. Website information, references to branded videos or virtual tours, builder promotion beyond simply stating the builder's company name, references to lender financing or preferred lender incentives, and any reference to a selling agent bonus or agent-facing incentive are all prohibited [3]. Information about the listing company or listing agent is not permitted in any publicly viewable text field, including public remarks [2].

What is allowed: seller-to-buyer incentives are fair game — if the seller is offering a closing cost contribution or a home warranty, you can say so [4]. The builder's company name for a new construction listing may appear [5]. And of course, the core purpose of the field — describing the physical property and its surroundings — is not just allowed, it's the point [6].

Content Type	Permitted in Public Remarks?
Physical property description (rooms, features, lot)	Yes
Neighborhood and vicinity details	Yes
Seller-to-buyer incentives (closing costs, warranty)	Yes
Builder's company name	Yes
Agent name or phone number	No
Agent or firm website URL	No
Branded video or virtual tour links	No
Preferred lender references or financing incentives	No
Agent bonus or selling agent incentive	No
Builder promotional language beyond company name	No

Public Fields Are Not an Advertising Channel

This principle is worth stating plainly because it runs counter to how many agents were trained to think about listing descriptions. Public fields should not be used as advertising for agents, builders, other properties, or any third party [8]. The MLS exists to give buyers and cooperating agents objective property data — not to give listing agents a free billboard.

In practice, this means your public remarks should read like a well-written property profile, not a promotional brochure. Lead with the home's strongest physical attributes: square footage, layout, standout finishes, lot size, views, recent updates. Follow with neighborhood context — walkability, proximity to schools or transit, community amenities. Close with any seller-offered buyer incentives if applicable. That structure uses your character budget efficiently and stays squarely within compliance.

One nuance worth knowing: virtual staging is acceptable as long as photo alterations affect only personal property like furniture and not the real estate itself [9]. If you reference staged photos in your remarks, make sure the staging disclosure is accurate and that no structural alterations have been digitally added to the images.

Writing High-Impact Copy Within the Character Limit

Once you know your MLS public remarks character limit and the content rules, the craft question becomes: how do you make every character count? Here is a practical framework.

Start with a strong opening clause that names the property's single best feature — not a generic opener like 'Welcome to this beautiful home.' Buyers skim; lead with the hook. Then move through the property in a logical sequence: main living areas, kitchen, primary suite, secondary bedrooms, outdoor space, and any notable mechanical or structural updates. Each detail should be specific — 'quartz countertops and a 36-inch gas range' beats 'updated kitchen' every time.

Save your final sentence for location context and any seller incentives. Something like: 'Half-block to Riverside Park; seller offering $5,000 toward buyer closing costs.' That closing line does double duty — it grounds the listing geographically and surfaces a buyer-facing incentive that is fully compliant [4].

Avoid filler phrases that eat characters without adding information: 'must see,' 'won't last,' 'priced to sell.' They signal nothing to a buyer and waste space you could use for a specific feature that actually differentiates the property.

Frequently Asked Questions About MLS Public Remarks Rules

Can I include my website in the public remarks?

No. Website information is explicitly prohibited in public remarks and any other publicly viewable text field [3]. Your website belongs in your agent profile, not in listing copy.

Can I mention a buyer agent bonus in the public remarks?

No. Any reference to a selling agent bonus or agent-facing incentive is prohibited in public remarks [3]. Additionally, a broker fee is not enforceable on the buyer's agent through the MLS [10], so this type of language creates both a compliance issue and a legal ambiguity.

Can I tell buyers about a seller concession in the public remarks?

Yes. Seller-to-buyer incentives — such as a closing cost contribution or a home warranty — are permitted in public remarks [4]. Agent-to-agent or seller-to-agent incentives are not.

Is the character limit the same on Zillow as on my MLS?

Effectively yes. Zillow pulls the public remarks field directly from MLS syndication, so your MLS character limit is the controlling constraint. There is no separate Zillow character limit to manage independently.

Can I mention the builder's name for a new construction listing?

Yes. The builder's company name is permitted in public remarks [5]. However, broader builder promotional language — marketing slogans, model names used as advertising, incentive programs — goes beyond what is allowed [3].
