Condo capital assessment framework (765 ILCS 605/18)
Non-emergency capital improvements exceeding 5 percent of the annual budget require 2/3 owner approval. Emergency assessments for immediate threats to structural integrity, health, or safety may be levied by board vote alone. Multi-year assessments are permitted; entire amount counts in year 1.
CICAA assessment framework
Board may levy emergency assessments unilaterally. Non-emergency improvements require majority owner approval at meeting. Budget increases above 115 percent of prior year trigger a member referendum if 20 percent petition. Multi-year assessments permitted.
Borrowing
Both statutes grant boards corporate borrowing powers without owner approval. Many declarations require approval for material loans. Loan obligations should be disclosed in resale certificate planned-capital sections.
Disclosure of pending assessments
Section 22.1 certificate must include planned capital expenditures for current and next 2 fiscal years. Approved-but-not-yet-billed and discussed-but-not-approved assessments may not appear. Read 18+ months of board minutes.
