For Urban Walkers, a Patchy Dilemma: Who Owns the Sidewalk?

July 06, 2026 — Linda Poon – Bloomberg
In 2007, New York City’s sanitation department threatened Natalie Shea with a $300 fine for defacing public property with graffiti. Her crime: drawing a blue flower in front of her family’s Park Slope home with sidewalk chalk. She was six years old. The incident, which made local and national news at the time, captures the fraught role that sidewalks often play in US cities. These patches of pavement do more than carry pedestrians to their destinations: They’re also places for commerce, social interaction and childhood play, from chalking to learning how to ride a bike. Urbanist Jane Jacobs once likened the range of activities that city sidewalks attract to an “intricate ballet.” In the new book Sidewalk Nation: The Life and Law of America’s Most Overlooked Resource (Harvard University Press), author Michael Pollack explores the “tangled web of state and local regulation” that governs sidewalks, with cities often passing along responsibilities for tasks like clearing snow and keeping walkways safe. He paints a portrait of the American sidewalk a disorderly and often neglected network, filled with literal and metaphorical cracks that give rise to all sorts of conflict, from mundane clashes over maintenance to more consequential fights over accessibility and inequality.

Preventing Common and Costly Water Intrusion Events in Construction

July 13, 2026 — Andrew Swift - Construction Executive
Water leaking into a building is a leading cause of damage and loss in the construction industry. On one jobsite, heavy rains flooded a sub-basement, damaging a new electrical transformer—all because a roof drain was not property connected. On another jobsite, a drinking-fountain supply line broke in a multistory building that was undergoing renovation, causing water to run—undetected—for an entire weekend, resulting in water damage to all lower floors, where construction had been finished. Those loss scenarios could have been prevented with a comprehensive and effective water damage prevention plan (WDPP). This includes routine site inspections to identify uncontrolled water damage exposures and basic maintenance to make sure drains are clean of debris and divert them to a catch basin or low point away from the building. An effective WDPP plan also incorporates technology such as backflow preventers on sewer connections and water sensing technology to monitor the most vulnerable exposures.

Construction Liens and the “Substantial Performance” Doctrine

April 08, 2026 — David Adelstein - Florida Construction Legal Updates
In a recent case dealing with a construction lien, the driving issue was whether the air conditioning contractor “substantially performed” before recording its construction lien against residential property. The importance here pertains to the substantial performance doctrine with respect to construction liens. The Third District Court of Appeal explained, with relevant citations, this doctrine as follows: Under Florida law, a contractor is entitled to a mechanic’s lien if he complies with all provisions of Chapter 713, governing construction liens, and “has substantially performed the contract.” Grant v. Wester, 679 So. 2d 1301, 1307 (Fla. 1st DCA 1996) (quotation omitted); Langley v. Knowles, 958 So. 2d 1149, 1151 (Fla. 5th DCA 2007) (“The substantial performance doctrine recognizes that a contactor who complies with all of the provisions of the contactor’s lien statute is entitled to enforce a lien if he has substantially, but not completely, performed his contractual obligations.”). Substantial performance is performance “so nearly equivalent to what was bargained for that it would be unreasonable to deny the promisee the full contract price subject to the promisor’s right to recover whatever damages may have been occasioned him by the promisee’s failure to render full performance.” Ocean Ridge Dev. Corp. v. Quality Plastering, Inc., 247 So. 2d 72, 75 (Fla. 4th DCA 1971). Read the full story...

Risks of Using an AI Chatbot for Legal Advice: Lessons from United States v. Heppner

April 08, 2026 — Payne & Fears LLP
Imagine that you are an executive (who is not a lawyer) and are concerned about what your company plans to do is legal. You could call your lawyer who might bill you for the call. Or, you can ask your AI chatbot, such as Claude or ChatGPT, about the legal risk. The chatbot will likely compliment you on the incisive question, provide you with highly confident answer (that may or may not be right) and will not bill you on an hourly basis. That is essentially what financial services executive Bradley Heppner did. It did not end well. A federal court recently ruled that Heppner’s chats with the AI tool Claude were not protected by attorney-client privilege or the work-product doctrine. That means that the other side (in this case, the federal government) could get access to his chatbot prompts, uploads and responses, and learn a great deal about, for example, whether Heppner knew what he was doing was illegal.

The Deadline to File Suit on a Public Works Payment Payment Bond is Triggered by a Claimant’s Work on a Project Not by a Claimant’s Work Under a Contract

June 02, 2026 — Garret D. Murai - California Construction Law Blog
California law requires that prime contractors furnish a payment bond – providing for payment to lower-tiered subcontractors and suppliers – on state and local public works projects with a value in excess of $25,000. There are three conditions that must be satisfied when a claimant makes a claim against a payment bond on a public works project in California:

1. First, generally, the claimant must have served a preliminary notice, unless the claimant is a first-tier subcontractor or supplier;
2. The claimant must have “ceased to provide work” on the project; and
3. The claimant must file suit against the payment bond no later than six (6) months after the period in which a stop payment notice must be given or, in other words, the earlier of 270 days after completion of the public works project or 210 days after a notice of completion or cessation was recorded on a public works project.

In Tarlton & Sons, Inc. v. Great American Insurance Company, 111 Cal.App.5th 376 (2025), the 2nd District Court of Appeal examined whether a subcontractor timely filed a claim against a payment bond when a prime contractor was terminated and replaced by another prime contractor who the subcontractor continued to perform work for.

From Dark Data to Building Intelligence

July 13, 2026 — Aarni Heiskanen - AEC Business
In this episode, I talk with Mark Sorsa-Leslie, founder and CEO of Auttaa AI, whose team just won first place in Luotea’s inaugural hackathon in Helsinki for turning property maintenance from reactive firefighting into proactive forecasting with AI. Mark is a chartered surveyor with 30 years of real estate data experience, previously the founder of the UK sensor company Beringar. We discuss why so much building data stays dark and siloed, from outdated networking technology to the shortage of people who understand both engineering and property. Mark explains how Auttaa bridges real-time building data with large language models, using what he calls an “influence graph” to surface correlations and causation across previously disconnected systems, such as linking occupancy patterns to CO2 readings to diagnose ventilation problems in minutes rather than days.

Insurer Cannot Raise Issues on Appeal that Were Not Presented to the Trial Court

June 15, 2026 — Tred R. Eyerly - Insurance Law Hawaii
The Florida Court of Appeals affirmed a judgment on a collapse claim for the insured, rejecting the insurer’s arguments that were not presented to the trial court. Homeowner’s Choice Prop. & Cas. Ins, Co. v. Oakes, 2026 Fl. App. LEXIS 2086 (Fl. Ct. App. March 18, 2026). The insured’s ceiling collapsed in the secondary home on the insured’s property. The claim was reported to the insurer, but coverage was denied after its investigation. The insured sued the insurer for breach of contract. Under the Additional Coverage provisions of the policy, collapse was covered if it was “abrupt.” An abrupt collapse was not covered, however, if exclusions for “Fungi, Wet or Dry Rot” and “faulty, inadequate or defective design, specifications, workmanship, repair, construction, renovation, remodeling, materials or maintenance” applied. The collapse provisions contained no language stating that the coverage granted in the provision was also subject to all the other exclusions in the policy. Read the full story...
