Every unit, its own lot.
Complete Condo Services has guided condominium conversions since 1996. We take buildings of 2 to 200+ units from the first document to a separate tax lot for every unit, across New York City and the tri-state area.
Over 30 years and thousands of repeat clients.
Since 1996 we’ve helped generations of owners convert their buildings across New York City and the tri-state area. Most of our work comes from clients who’ve done it with us before.

Questions
Don’t see yours? Call us. After 30 years, we’ve probably heard it.
What is a condominium conversion?
It’s the legal process of dividing a building into units that can each be owned, sold and mortgaged separately. In New York it involves an offering plan reviewed by the Attorney General, a condominium declaration, and city filings that give every unit its own tax lot.
What size buildings do you handle?
Any size, from 2-unit buildings to 200 units and beyond: small multi-family homes, mid-size and large apartment buildings, new construction and mixed-use properties.
Where do you work?
All five boroughs of New York City and across the tri-state area. Our office is at 610 Broadway in Brooklyn.
Do I still need an attorney?
Yes. The offering plan and declaration are legal documents prepared by an attorney. We aren’t a law firm. We work alongside your attorney and handle the coordination, document gathering and agency work around them.
How long does a conversion take?
It depends on the building, how quickly documents come together, and review times at the Attorney General and city agencies. After intake we’ll give you a realistic estimate for your building.
My conversion is already started. Can you take it over?
Yes. We step into stalled or half-finished files, work out what’s missing and move them forward.
What happens after the offering plan is accepted?
The plan has to be kept current with amendments. We track the deadlines and help prepare extension and post-closing amendments so it doesn’t lapse.
Do you only work on conversions?
No. We also handle Exhibit I and III, confirmatory deeds, easements and restrictive declarations as standalone jobs, from order through recording.
