What is a Joist? Understanding Its Role in Balcony Inspections
Table of Contents
Balcony safety is a critical aspect of building maintenance, especially in states like California, where regulations such as SB 326 inspection and SB 721 inspection mandate regular inspections of exterior elevated elements (EEEs). One of the key components of any balcony or deck structure is the joist, which plays a significant role in the stability and safety of the structure. But what exactly is a joist, and how can an engineer assess its condition? This blog will delve into the importance of joists and the inspection process that ensures your building’s balconies meet the required safety standards.
What Is a Joist and Why Is It Important?
A joist is a horizontal structural component that supports the decking of a balcony or deck. It is typically made of wood, steel, or engineered wood products, and it is positioned between beams to distribute weight and provide stability to the balcony. Joists are essential because they ensure that the balcony can safely support the load of people, furniture, and other elements without bending, warping, or failing.
Over time, joists can become compromised due to wear and tear, moisture, or exposure to the elements, particularly in climates like California where extreme weather and moisture can weaken the structural integrity. A compromised joist can lead to unsafe conditions, including sagging or collapsing balconies, making it vital to inspect them regularly.
How Can an Engineer Inspect the Condition of a Joist?
Determining the condition of a joist involves several steps, from visual inspection to more advanced diagnostic tools. Below are the key ways an engineer can assess whether the joist is in good condition or in need of repair or replacement.
What Are the Signs of Joist Damage?
The first step in assessing a joist is a visual inspection. During this stage, an engineer will look for the following signs of damage:
- Cracks or Splits: Joists that have large cracks or splits may not be able to support the balcony’s load effectively.
- Sagging or Bowing: If the joist is sagging, this indicates that it may no longer be structurally sound.
- Water Damage or Rot: Joists, especially wooden ones, are susceptible to moisture damage. Water intrusion can lead to wood rot, which significantly weakens the structure.
- Corrosion: In steel or metal joists, rust and corrosion are clear signs that the joist has been compromised and could lead to structural failure.
These signs may indicate that the joist has deteriorated, but further tests may be required to assess the full extent of the damage.

While visual inspections are helpful, engineers often use more advanced tools to determine the joist’s condition thoroughly. Some of these tools include:
- Moisture Meters: These devices detect the amount of moisture present in wooden joists, which is important for identifying hidden wood rot or water damage.
- Infrared Cameras: Infrared cameras can detect temperature variations, which may indicate areas where moisture has infiltrated the joist. This is particularly useful for spotting hidden damage.
- Load Testing: In some cases, engineers will conduct load tests to determine whether the joist can still support the intended weight. Load testing applies pressure to the joist to see if it responds within safe parameters.
- Core Sampling: This involves taking a small sample of the joist to test its internal condition. Core sampling can reveal signs of decay or damage not visible from the surface.

My property is well-maintained. Do I really need SB-326/SB-721 inspections?
YES! Even with excellent maintenance, hidden issues can develop due to construction errors, material flaws, or severe weather exposure. Inspections are about ensuring those don’t turn into major problems.
Our balconies were inspected a few years ago – isn't that enough?
Unfortunately, no. California laws mandate inspections on a set schedule, often every 6 years. Deterioration can happen quickly, making regular assessments essential.
Can I use my regular handyman for the balcony inspection?
It’s not recommended. Unless they hold specific licenses (architect, structural engineer, etc.) their inspection won’t be considered valid for SB-326/SB-721 compliance.
What if the inspection uncovers major issues?
First, don’t panic! Early detection often means less extensive (and expensive) repairs are needed. Work with your inspector to prioritize fixes, and explore if they offer repair services for a streamlined solution.
I'm worried about the cost of inspections. Are there any resources to help?
Start by getting detailed quotes from multiple companies. Factor in that proactive inspections help you avoid even bigger costs down the line due to neglected problems. Some property management associations offer guidance on budgeting for balcony compliance.

I started off by doing 1 inspection with them back in June because I knew it needed work done. Now, they’ve completed 2 of my properties and have 2 more inspections coming up this month. All great so far! They’re great at keeping me updated
