New York commercial space, matched

Every floor has a tenant looking for it.

Post the space you have or the space you need. Leasemark reads both sides, lines them up floor by floor, and shows you the score.

Have space? Listing is free, with no fees, no commission and no exclusive, so the same space can stay on LoopNet or Crexi too. Tenants, buyers and tenant rep brokers find it on Leasemark's search and neighborhood pages, and it is matched against every active requirement the moment you post. List a space, or upload a sheet or a CoStar or LoopNet export of up to 50 spaces.

Need space? Post what you need for free: the type of space, the neighborhoods, a size range, a budget and a move-in date. You need no broker, and a tenant rep can post it for you. Owners and listing brokers see the need but not your name or company, and every space that fits reaches you with a score, including spaces listed later. Post it here: https://leasemark.co/post/requirement

Or post a requirement and let listings come to you.

Questions

Straight answers before you post.

What is Leasemark?

A free marketplace for New York City commercial real estate. Owners, landlords and brokers list office, retail, industrial, flex, medical and restaurant space and development land, for lease, sublease or sale. Tenants, buyers and tenant rep brokers post the space they need. Leasemark scores every space against every requirement and introduces the two sides when both say yes.

Is it free to list commercial space on Leasemark?

Yes. Listing space, importing an availability sheet, seeing matched requirements and requesting intros are free, and they stay free. Broker Pro and Featured boosts will be optional paid extras, and neither is charging yet.

Can I list a space that is already on LoopNet, Crexi or another site?

Yes. Leasemark does not ask for an exclusive, so list the same space here as well as on LoopNet, Crexi, your own website or a sign in the window. What it adds is the other side of the market: tenants, buyers and tenant rep brokers post what they need here, and your space is scored against every active requirement the moment it is listed. Have a flyer or a listing write-up already? Paste its text or choose the PDF on the listing form, and the form fills itself in.

I own the building. Can I list it myself?

Yes. Owners list the same way brokers do, free, and every space is matched against every active requirement. If you are filling a space yourself, our landlord's checklist walks through the legal use, pricing it with city data, marketing, screening tenants, the lease and the filings the city expects afterwards. Read the landlord's checklist.

Does Leasemark take a commission or a co-broke split?

No. Leasemark is a marketplace, not a brokerage. We do not represent either side, we do not take a share of the deal, and your fee arrangement with your client is untouched.

How do I find commercial space as a tenant?

Search the listings by neighborhood, type and size, or post a requirement: the type of space, neighborhoods, size range, budget, move-in date and must-haves. Posting is free. Owners see your requirement but not your name, and spaces that fit reach you with a score and the reasons behind it, including new ones the day they list.

How do intros work?

Either side can request an intro on a match, and contact details are exchanged only after the other side says yes. A listing or a requirement can also turn on direct contact, which puts a Contact button with the poster's details on its page.

Which areas does Leasemark cover?

80 neighborhoods across Manhattan, Brooklyn, Queens, the Bronx and Staten Island, plus Jersey City. Every large office, retail and industrial building we track also has its own page with its size, owner of record and estimated property tax from city records.

Are the listings and requirements real?

Posts without a label come from real owners, brokers, tenants, buyers and reps. A few demonstration posts carry an Example label. They never match real posts and are never counted in any number on the site.
