California Lawyers Association (CLA) Real Property Law E-Bulletin article: “Navigating Land Use Permitting During A Pandemic”

As of the date of this article, we are in week 18 of the shelter-in-place (SIP) order first issued by the State of California Public Health Officer on March 18.  In the early days of the pandemic, land use development immediately saw construction halted, planning departments shut down, and permit processing paused.  We saw wide disparities among jurisdictions throughout California as to the strictness of SIP orders, restrictions on active construction projects, and the availability of online permit processing tools.  Below is a summary of some of the specific challenges attributable to the SIP orders in the areas of construction, due diligence, and land use permitting, as well as updates on how things have evolved over the past four months.
