How do you figure undivided interest in a condominium?

Every condominium community calculates this differently, and your answer is available in your governing documents.

Look in every index for 'Allocated Interest', and review which scheme is in use for your community.

Often, interest is divided by unit square footage, or a raw percentage of total ownership.

• The square footage model is usually used in communities where some units are situated in a more 'desirable' location than other units, i.e., top floor penthouses.
• The raw percentage model is used if all units are equally desirable and of an equal size.

To find the particular undivided interest of any particular unit can be difficult in some cases. If all the units were created at the same time, the common interests remain static and can usually be determined by an exhibit attached to the Master Deed. That information is required by most, if not all, condominium statutes.

However, in some jurisdictions, condominium projects are created in phases over a period of time. In that case, when completed units are sold, the developer builds a few more units using the proceeds. As units are added the undivided interests change for all the units (so they always add up to 100%) and are set forth in a new exhibit to each phasing amendment to the Master Deed. The final analysis can be difficult to determine and must be accomplished by a review of all the condo documents that have been recorded in the land records.
