Tax season ends. Family begins.

Adopt a relative.
Avoid a pied-Γ -terre tax.

New York's new vacancy surcharge punishes empty second homes. We connect property owners with warm, dependable, tax-exempt-by-blood strangers willing to be legally adopted into the family β€” so your Tribeca pied-Γ -terre stays beautifully occupied and 100% tax-free.

How it works

Three steps to a beautiful, tax-deductible bond.

We've streamlined kinship the way Stripe streamlined payments. It's almost uncomfortable how easy this is.

01

Browse the family tree.

Filter prospective relatives by warmth, discretion, dietary requirements, and ability to call you "Mama" without flinching at the holiday table.

02

Sign the paperwork.

Our white-shoe partner firm handles the adoption, the deed, the trust amendment, and the awkward email to your actual children.

03

Skip the tax. Forever.

Your new relative moves in. The unit is occupied. The auditor exhales. You exhale. Everyone wins, except the city budget.

The marketplace

Meet your new family. Or your new home.

Every listing is background-checked, vibe-checked, and lightly notarized.

Real warmth. Real loopholes.

I now have a son named Brent. He lives in my Soho place, waters the orchids, and saved me $97,000 last quarter. We're closer than I am with my actual kids.

I went from couch-surfing in Bushwick to brownstone-sitting in the Heights. My new "mother" lives in Aspen. I water the fig. I am the fig now.

The tax was a vibe killer. Heirbnb sent over a charming young man named Aleksei who calls me Tante on Tuesdays. We've never been happier. The auditor agrees.

Questions you whispered to your accountant

Frequently dodged questions.

Is this… legal?

Heirbnb operates in the lush grey area where the tax code meets the family code. Our adoptions are real, our deeds are real, and our paperwork has been very lightly winked at by a real lawyer. Consult yours.

What if I already have children?

You can have more. Many of our most successful clients describe their original children as "starter children." Your new relative will be told about them on a need-to-know basis.

Can my adoptee throw parties?

Family plans of The Heir Apparent tier and above include two (2) tasteful gatherings per quarter. Dynasty members may negotiate a private nightclub clause.

What if we don't get along?

Our concierge team handles emotional disentanglement, legal de-adoption, and a courteous goodbye basket. Most families just stop returning each other's calls β€” which, statistically, is normal.

What if the city closes this loophole?

We have already begun work on Heirbnb 2: trust-based shell families. Your subscription will be grandfathered. Pun very much intended.

Is this a real website?

No. This is satire. Please do not adopt a stranger to dodge a tax. Probably.

Your apartment is empty.
Your family doesn't have to be.
