Background

Presidential Dental Associates leased Chicago dental-office space from 560 W. Washington (Chicago) LLC under a 10-year lease that expired December 31, 2023. The lease gave the tenant two five-year renewal options if it was in good standing and gave six months’ notice. Renewals would be on the same terms, except that the rental rate and “other associated deal concessions,” including free rent and tenant-improvement allowances, would be at fair market value. The parties then had 30 days to negotiate the renewal rent.

The dental practice alleged it timely exercised its first option and had invested about $167,000 in permanent improvements beyond the landlord’s $40,000 construction allowance. The parties did not agree on renewal terms. The tenant sued for specific performance and breach of contract; the landlords moved for summary judgment, contending the renewal provision was too indefinite to enforce.

The Court’s Holding

The appellate court affirmed summary judgment for the landlords. Although a fair-market-value rent term can ordinarily supply a sufficiently definite price, this renewal clause also left “other associated deal concessions” for future negotiation, including undefined items encompassed by “etc.” The court held that those unresolved terms made the renewal provision too indefinite for specific performance.

The court also rejected the breach claim premised on an alleged independent duty to negotiate in good faith. Illinois does not recognize an independent cause of action for breach of the implied covenant of good faith, and the negotiation language was intertwined with the unenforceable renewal clause. Finally, equitable estoppel could not defeat summary judgment because the tenant had not specifically pleaded that theory in its complaint.

Key Takeaways

  • A fair-market-value rent standard may be enforceable, but additional material renewal terms cannot be left undefined for later negotiation.
  • An implied duty of good faith does not create an independent Illinois claim for failure to negotiate an otherwise unenforceable renewal.
  • Equitable estoppel must be specifically pleaded; raising it for the first time in summary-judgment briefing is insufficient.

Why It Matters

Commercial lease renewal provisions should identify all material economic terms or provide an objective method for determining them. A clause that fixes rent by market value but leaves concessions and other deal terms open can fail for indefiniteness.

The decision also underscores the pleading consequences of relying on equitable theories: tenants seeking estoppel must place that defense or claim in the pleadings before summary judgment.
