Lienor Dealing With “Show Cause” Summons by Condominium Unit Owner

September 01, 2026 — David Adelstein - Florida Construction Legal Updates
One of the statutory vehicles to shorten a construction lienor’s statute of limitations to foreclose on a construction lien is through a “show cause” summons that essentially requires the lienor to foreclose on the lien within 20 days from receipt of the “show cause” summons. This is a statutory procedure under Florida’s Lien Law in Fla. Stat. s. 713.21(4). If a lienor receives a “show cause” summons and lawsuit, the lienor should, without delay, counterclaim or file a separate lien foreclosure lawsuit within the 20-day period without exception. This is provided the lienor wants to move forward with its lien. If a lienor does not, the lien will be discharged of record. If you are a lienor and receive a “show cause” summons, please immediately consult with construction counsel that can best advise you and perfect your lien rights. Read the full story...

In the recent case of Cty. of Erie v. Selective Ins.

Builders Oppose Senate Housing Bill Over Investor Ban Provision

March 24, 2026 — Katy O'Donnell - Bloomberg
A powerful group representing the nation’s home builders is coming out against the most significant housing legislation in more than a decade over a provision negotiated by the White House that would restrict institutional investors from purchasing single-family homes. The builders’ objection could imperil the bill’s chances of becoming law, even as leaders of both parties are desperate to show they are doing something to alleviate voters’ cost-of-living concerns. The Senate voted 90-8 to clear a procedural hurdle for the bill on Wednesday, with a vote on final passage expected early next week. The inclusion of the investor ban in a broader housing bill was key to getting the White House on board, Senate Banking Committee Chairman Tim Scott, a Republican from South Carolina, told reporters Tuesday.

Prefatory Contract Language Cannot Be Used to Create an Ambiguity with Operative Provisions

May 12, 2026 — David Adelstein - Florida Construction Legal Updates
Contract drafting and interpretation matters. A case dealt with the potential conflict with prefatory language in an agreement compared with operative provisions in the agreement. The trial court held that the operative provisions control. I discussed this case here where the appellate court reversed based on the prefatory language. But, through a motion for rehearing, the appellate court reconsidered its position and affirmed the trial court based on the operative provisions, mainly that the prefatory language cannot be used to create an ambiguity with operative provisions. Consider this explanation in affirming the trial court:

Because the trial court correctly found that the initial language in the contract was prefatory and could not be used to create an ambiguity in the remainder of the contract, we affirm the final judgment.

Kahana Feld Obtains Favorable Result in High-Exposure NY Premises Liability Case

June 15, 2026 — Leigh Katz - Kahana Feld
Kahana Feld partner Leigh Katz obtained a significant victory in a recent matter involving a videotaped alleged trip and fall on the sidewalk in front of the client’s commercial residence. The plaintiff claimed he suffered a knee injury that necessitated surgery, along with other assorted injuries that prevented him from continuing high-level athletic activities. Leigh was able to demonstrate that the fall was staged and received a voluntary discontinuance with prejudice. At mediation, Leigh emphasized that KF’s expert witness challenged the plaintiff’s claim that the fall was caused by a sidewalk height differential after reviewing the videotape footage and determining the plaintiff’s fall began before his feet made contact with the alleged defect. Based on this analysis, the expert concluded the reported height differential did not initiate the fall, which supported KF’s position that the incident depicted in the video was unrealistic and appeared staged.

Applying Jury Verdict Method in Quantifying Damages Due to Defective Specifications

March 31, 2026 — David Adelstein - Florida Construction Legal Updates
An older case deals with three important considerations: (1) defective specifications; (2) whether the defective specifications were misleading or misrepresentative; and (3) applying the jury verdict method in quantifying damages. In Metric Construction Co., Inc. v. U.S., 80 Fed. Cl. 178 (Fed. Cl. 2008), a contractor was contracted by the federal government to construct a warehouse. There were defects in the structural steel design specifications underlying the standing seam metal roof installed by the contractor and, as a result, the roof system leaked causing damage. The contractor incurred significant costs in repairing the damage, and pursued recovery of these costs against the government. The contractor claimed the structural steel design serving as the framework for the metal roof was defective and misleading and caused the leaks. Read the full story...

How Mobile Tools Are Capturing Safety Data on Jobsites

April 08, 2026 — Michael Bruns - Construction Executive
Traditionally, construction safety management is “reactive compliance”—reporting on an incident, filling out a form on paper or electronically, taking a picture and filing it away for compliance purposes. Safety management is shifting from reactive to proactive. Forward-thinking companies are using data and leading indicators to identify risks before incidents happen, not just document injuries after the fact. Mobile tools have completely changed the way safety operations work on construction sites, enabling that transition to proactive safety management.
