CA Senator Jerry Hill Introduces SB-721 Contractors: decks and balconies: inspection Supports Requiring Deck Inspections

Bill Duplicates Berkeley Bill Langauge in Who Can Perform Inspections

Should structural pest control operators, general contractors, architects or engineers inspect deck inspections as the state of CA is proposing?

They will be if the consulting and inspection industry doesn’t act quickly and object. Senator Hill has just introduced a bill that uses much the same language Berkeley’s city ordinance does.

“The inspection shall be performed by a licensed general contractor, structural pest control licensee, licensed architect, licensed engineer, or other licensee as approved by the Department of Consumer Affairs. The purpose of the inspection is to verify that all of the balconies and other elevated walking surfaces covered by this section are in generally safe condition, adequate working order, and free from hazardous dry rot, fungus, deterioration, decay, or improper alteration to the extent that the life, limb, health, property, safety, or welfare of the public or the occupants is not endangered.”

My thoughts-

Structural Pest Control Licensee-pest control licensee’s inspect buildings for termites/wood destroying organisms. They do not test roofs (or balconies) for water tightness, nor are they qualified to do so. Roof contractors can do so, but generally exclude themselves from inspecting decks. Pest control licensee’s do not know about waterproof coated decks, how they are installed, what problems to look for when doing an inspection and even if they do see a problem, don’t understand what caused it, what degree of a problems it is or how to repair it.

General Contractors-Most GC’s I know don’t know much about waterproofed coated decks and even less about the problems they may have. Indeed, I give seminars on Best Building Practices Building & Waterproofing Decks where the room is filled with GC’s. Ask a GC about flashings and door pans and coating application procedures and their eyes will usually glaze over; they just don’t know. Think of a General Contractor as a Doctor practicing general medicine-they know enough to get by and enough to refer you to a specialist. You wouldn’t go see your general practitioner for a heart problem and you wouldn’t call a General Contractor to come fix your waterproof deck. You would call a specialist who practices waterproofing every day just like you’d call a heart specialist for an operation.

Architects- in my review of the plans for Berkeley, I found multiple design issues with the deck plans. I called a friend of mine who graduated from the Cal-Poly SLO school of architecture and asked him how many classes or lectures he had on waterproofing in general and deck waterproofing specifically. None was his answer. I checked various architecture schools websites for classes on waterproofing. I am still searching, there’s got to be one.  I’ve been on jobs arguing with the architect about his design and how I’m supposed to waterproof it in…they are asking me what I think. Listen you are the one with the degree you just threw in my face; you design the waterproofing system, I’m only the waterproofing contractor.  Either I walk off the job because they’re an egotist asshole or they admit they need my help and I help them. What makes anyone think they know what’s wrong with a waterproof deck?

Engineers- Unless the intent is to push business to the large waterproofing consulting firms, who charge fees that many can’t afford, few engineers are or want to be qualified to inspect waterproofing projects.

So Who Should Be Inspecting Waterproof Decks?

Answer-Qualified Deck Inspectors. What makes a “qualified” deck inspector? People who have been in the trade. People who actually have experience installing waterproof decks.

Members of NADRA, the North American Deck & Railing Association, has a deck inspection course and qualified deck inspectors many of whom are also home inspectors.

I believe a course on how to inspect waterproof decks, with a checklist of items to use during the inspection, should be developed. As with home inspectors, no license is required. This should be the case here as well. There are many qualified individuals who could perform deck inspections but would be removed from doing so if the bill passes with it’s current language. recommends changes to the bill in regards to who can perform the deck inspections. What do you think?

Waterproofing Classifications CSLB-Maybe a license classification for waterproofing contractors should be reinstated by CSLB, currently several classes of contractors can waterproof decks, inc roofers, painters and synthetic products contractors. This creates confusion and disparity in the industry as roofers even of they are exempt from workers comp because they have no employees, must still have a workers comp policy in place. A painter is exempt from being required to have workers comp as is the synthetic products contractor.


The full text of the bill is below. Please register and comment on the bill to add your thoughts.

An act to add Section 7071.20 to the Business and Professions Code, relating to contractors.



SB 721, as introduced, Hill. Contractors: decks and balconies: inspection.
Existing law provides authority for an enforcement agency to enter and inspect any buildings or premises whenever necessary to secure compliance with or prevent a violation of the building standards published in the California Building Standards Code and other rules and regulations that the enforcement agency has the power to enforce.
This bill would require the inspection of decks, balconies, and elevated walkways more than 6 feet above ground level in a building containing 3 or more multifamily units by a person licensed to perform these inspections by the Department of Consumer Affairs. The bill would require the inspections and any necessary repairs to be completed by January 1, 2021, and would require subsequent inspections every 5 years, except as specified. The bill would require a copy of the inspection report to be filed with the county recorder and made available, as specified. The repairs made under these provisions would be required to comply with the latest edition of the California Building Standards Code and all local jurisdictional requirements. The bill would authorize local enforcing agencies to recover enforcement costs associated with these requirements.
Because this bill would impose new duties upon local enforcement authorities, it would impose a state-mandated local program.
The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement.
This bill would provide that no reimbursement is required by this act for a specified reason.



Section 7071.20 is added to the Business and Professions Code, to read:


(a) All buildings containing three or more multifamily dwelling units, any existing balcony or other elevated walking surface exposed to water, including, but not limited to, rain, snow, or irrigation, with structural framing that is protected by an impervious moisture barrier shall be inspected. For purposes of this section, balconies or other elevated walking surfaces less than six feet above grade are not included. The inspection shall be performed by a licensed general contractor, structural pest control licensee, licensed architect, licensed engineer, or other licensee as approved by the Department of Consumer Affairs. The purpose of the inspection is to verify that all of the balconies and other elevated walking surfaces covered by this section are in generally safe condition, adequate working order, and free from hazardous dry rot, fungus, deterioration, decay, or improper alteration to the extent that the life, limb, health, property, safety, or welfare of the public or the occupants is not endangered.

Building elements, including the walking surface, structural frame and connector hardware, weatherproofing, landings, stairway systems, guardrails, handrails, and any other elements critical to the safety of the balcony or elevated walking surface, found to be in need of repair or replacement, hazardous, structurally deficient, or noncompliant shall, upon determination by the licensed professional, be immediately corrected by the property owner or individual responsible for management or operation of the building. All necessary permits for repair or replacement of exterior balconies and elevated walking surfaces shall be obtained from the local jurisdiction. All repair and replacement work, including installation and inspection of impervious moisture barrier systems, must be performed in compliance with manufacturer’s instructions, the latest edition of the California Building Standards Code, and all local jurisdictional requirements.
(b) The inspection and repairs shall be completed by January 1, 2021, and every five years thereafter. The licensed professional conducting the inspection shall produce an initial report that states the condition of the building features and recommendations for repair, conditioning, or replacement and a final report indicating that all of the required repairs have been completed. A copy of the final report shall be submitted to the county recorder for recordation. Local enforcing agencies may determine the information to be provided in the report and require a copy of the initial or final reports, or both, to be submitted to the local jurisdiction in lieu of recordation.
(c) Multifamily buildings of three units or more for which a building permit application has been submitted on or after February 1, 2017, are exempt from the inspection certification requirements for a period of five years following issuance of a certificate of occupancy from the local jurisdiction.
(d) The continued and ongoing maintenance of balconies and elevated walking surfaces and parts thereof, in a safe and sanitary condition, shall be the responsibility of the owner or the owner’s designated agent. To determine ongoing compliance with this subdivision, the enforcing agency shall have the authority to require reinspection of those structures.
(e) Local enforcing agencies shall have the ability to recover enforcement costs associated with the requirements of this section.

SEC. 2.

No reimbursement is required by this act pursuant to Section 6 of Article XIII B of the California Constitution because a local agency or school district has the authority to levy service charges, fees, or assessments sufficient to pay for the program or level of service mandated by this act, within the meaning of Section 17556 of the Government Code.

San Francisco Chronicle & Los Angeles Times Utilize Our Expertise in Understanding the Berkeley Deck Failure

Building & waterproofing decks isn't hard, but the devil is in the details and proper design and sequencing the construction is essential to a successful job.
No one wants to see a headline like this, with 6 dead & 7 others seriously injured.
Both the LA Times & San Francisco Chronicle have used us as a source
on their investigative articles. provides consumers with information, videos articles and more for buyers to make informed decisions on deck systems. We also provide articles to major trade magazines for the HOA, Construction and Architectural industries. 

Now we are pleased to say our expertise is helping reporters understand the problems that caused the recent Berkeley deck tragedy where the a waterproofed balcony, only 7 years old, failed catastrophically and thirteen people plunged to the ground, killing six and seriously injuring the other seven survivors.

Both the the Los Angeles Times and the San Francisco Chronicle have interviewed us for their investigative articles into the how and why this tragedy occurred.

From the Chronicle  article-This is all a vicious combination,” Leys said. “The penetrations, the drainage and lack of ventilation underneath — they all combined in a catastrophic failure.
