Checking whether storage is part of the unit or separately assigned
Learn how to determine if your condo storage space is deeded to your unit or a limited common element to avoid ownership and maintenance surprises.
The short answer
In Illinois, condo units consist of specific boundaries, while common elements serve the entire association. Storage areas are often designated as limited common elements reserved for specific units rather than deeded property. Reviewing the declaration and the plat of survey is essential to confirm if your storage space is legally tied to your unit or assigned by the board.
Understanding Unit Boundaries and Common Elements
Illinois law defines unit boundaries typically by finished surfaces like flooring and paint. Everything outside these boundaries is usually a common element. Before assuming a storage locker belongs to you, verify if it falls within your unit's legal description found in the declaration.
Identifying Limited Common Elements
Storage units are frequently classified as limited common elements. This means they are reserved for your exclusive use, though you may not technically own them in fee simple. Check if your declaration explicitly mentions these areas as being allocated to your specific unit number.
Consulting the Recorded Plat
The plat of survey, which must be recorded with the declaration, acts as the official map for your property. A licensed Illinois Land Surveyor provides these details. If your storage space is not clearly mapped on this document, it may be a common area managed entirely by the association.
Planning Your Research Worksheet
Create a worksheet to track your findings: 1) Does the declaration list the storage unit as part of the unit's percentage of common elements? 2) Is there a separate assignment letter? 3) Does the board hold the right to reassign the space? 4) Are there monthly fees specifically tied to this storage area?
Checklist
- Request the full declaration from the association management.
- Obtain the recorded plat of survey from your closing agent.
- Check the unit's legal description for storage space mentions.
- Ask the board if storage assignments are recorded in minutes.
- Confirm if the space is treated as a limited common element.
Common questions
Can the association take back my storage unit?
If the space is a limited common element defined in the declaration, your right to use it is generally protected under the governing documents unless the declaration provides specific board authority for reallocation.
What if my storage space is missing from the legal description?
If it is not in the legal description or on the plat, ask the board of managers to provide written clarification on the usage status and whether this usage is revocable.
