2020 California Construction Law Update


As 2020 fast approaches, we ring in many new changes to California’s construction laws.

Among other changes, California adopted its 2019 triennial revisions to the California Building Code which take effect on January 1, 2020. Revisions include aligning state structural steel and masonry construction engineering requirements with national standards, minor revisions to standards for wood construction, support and anchorage requirements of solar panels in accordance with industry standards, and clarification of testing and special inspection requirements for selected building materials during construction.

On the state legislative side, California enacted a number of new laws in the areas of affordable housing and alternative energy use.

So, without further ado, here are the new laws going into effect on January 1, 2020:

Reduces the number of days a lead agency is required to approve or disapprove a project from 120 to 90 days for a development project and 90 to 60 days for a development meeting certain affordability conditions. Prohibits a county or city from enacting policies, standards, or conditions changing land use designation or zoning of property a less intensive use within an existing zoning district below what was allowed under the general plan or specific plan land use designation and zoning ordinances of the county or city; impose or enforce a moratorium on housing development; impose or enforce non-objective new design standards; or establish or implement limits on number of permits issued.

AB 68/AB 670/AB 881/AB 587/SB 13 – Deletes minimum lot size requirements to build an accessory dwelling unit (aka in-law unit) and prohibits imposition of limitations on lot coverage, floor to area ratio, open space, and minimum lot size if they prohibit construction of accessory dwelling units meeting those limitations. Makes any covenant, restriction, deed, contract, security instrument, or any provision of a governing document that prohibits or restricts the construction of an accessory dwelling unit on a lot zoned for single-family residential void and unenforceable.

AB 1485 – Adds a new class of eligible projects qualifying for streamlined permitting approval under SB 35 because of the difficulty for developers to meet the affordability requirements of SB 35.  Adopted in 2017, SB 35 requires local entities to approve certain housing projects through a ministerial approval process within certain timeframes and excepted from the California Environmental Quality Act (CEQA) analysis as well as Conditional Use Authorization requirement.

Projects located in certain qualifying San Francisco Bay area cities or unincorporated areas (Counties of Alameda, Contra Costa, Marin, Napa, San Mateo, Santa Clara, Solano, Sonoma, and San Francisco), containing 10 or more units and providing 20% affordable housing to households earning below 120% AMI, qualify for streamlined project approval.

Participating counties must submit a report describing, among other things, the projects awarded using the best value procedure.
