Does your balcony comply with SB 721
(California State Balcony Inspection Law)?

SB 721 (Chapter 445, Stats. 2018) was signed by Governor Brown in response to the 2015 Berkeley balcony collapse. The balcony collapsed due to decayed wooden joist; six young adults on the balcony were killed and seven others were injured, mostly Irish citizens, visiting California as part of UC Berkeley's summer exchange program. While some local governments already impose a local inspection program, this California law requires inspection of specific balconies throughout California.

What Building Must Be Inspected?

Building with 3 or more units that have:

  • Balconies, decks, porches, stairways, walkways and entry structures that extend beyond exterior walls of the building and that rely in whole or in substantial part on wood or wood-base products for structural support or stability; and
  • A walking surface that is elevated more than 6 feet above the ground level; and
  • Balconies designed for human occupancy or use.


Buildings that are proposed for conversion to condominiums to be sold to the public after January 1, 2019, must be inspected prior to the first close or escrow to see if they need balcony repairs.

When Must the Building be Inspected? Inspections of the balconies, decks, porches, stairways, walkways, and entries as described above must be inspected by January 1, 2025, with certain exceptions, and requires subsequent inspections every 6 years.

The inspection of building for which a building permit application has been submitted on or after January 1, 2019, shall occur no later than 6 years following issuance of a certificate of occupancy from the local jurisdiction and shall otherwise comply with the provisions of this law.

If the property was inspected within 3 years prior to January 1, 2019, by an inspector as described in the law and a report of that inspector was issued stating that the exterior elevated elements and associated waterproofing elements are in proper working condition and do not pose a threat to the health and safety of the public, no new inspection shall be required until January 1, 2025.

  • Licensed civil or structural engineer,
  • General Contractor holding any or all A, B, or C-5 License issued by the Contractors State License Board with a minimum of 5 years’ experience in constructing multistory wood frame buildings;
  • Individuals certified as a building inspector or building official, as specified; (these individuals cannot be employed by the local jurisdiction while performing these inspections).

What Must the Inspector Cover?
The inspector required by this law must, at a minimum, include:



  • Identification of each exterior elevated element or associated waterproofing elements that, if found to be defective, decayed or deteriorated to the extent that it does not meet its load requirements, would, in the opinion of the inspector, constitute a threat to the health or safety of the occupants.
  • “Associated waterproofing elements” are define to mean slashing, membranes, coating and sealants that protect the load-bearing components of exterior elevated elements from exposure to water and the elements.
  • Assessments of elevated elements using methods allowing for evaluated of their performance by direct visual examination or comparable means of evaluating their performance. For purposes of this section, a sample of at least 15 percent of each type of exterior elevated element shall be inspected.
