Task 1. Decay Protection Inspection
Newly constructed homes that aren’t inspected for decay and water intrusion have the ability to become compromised. Water can enter into the walls, causing mold growth, rot and structural issues at the worst. These issues can become very costly to those who live in the home, there can also be health related problems that may arise. Having a home inspection is very important in uncovering these possible issue before they become major problems.
While a home inspector is not expected to provide an engineering analysis, he or she should be alert to possible issues with the allowable spans and materials in a home. In some cases the inspector may notice sagging in the framing which could indicate an issue with materials and span. I inspected a new home with a very loud squeak in the flooring in the entryway, but there was no noticeable or visible sagging in the joists in the crawlspace. When we had a structural contractor check the framing with a laser level, we discovered that the floor joists had been placed 20 inches on center instead of 16 inches as called for in the plans. All new homes should be inspected before the expiration of the warranty period.
Pretty much every course is this way when an entire lesson within the course is a video. Any time you close the course and/or log out, the system will only track what lesson/page you were on, not where you were in the video. The video lessons in this course are pretty long, so just plan enough time to get through an entire video before stopping, otherwise you will have to keep doing what you are doing.
Remember, if you do finish a video lesson and want to call it quits for the day, be sure to click the “Next” tab at the bottom of the page. If you don’t, the system won’t know that you actually finished the video and will have you play the video again before it will let you move on.
Decay protection is a vital consideration when inspecting residential properties, as it directly impacts the structural integrity and longevity of a home. Without proper safeguards against moisture intrusion and decay, a home can quickly deteriorate, leading to significant repair costs and potential health hazards.
Neglecting inspections or conducting inadequate ones can have serious consequences. In a newly constructed home, failure to inspect for water intrusion can lead to structural decay before the homeowner even moves in. Moisture that enters the home through improperly sealed areas or damaged roofing can cause wood rot, mold, and mildew, which can go unnoticed in the early stages but result in costly repairs later on. Moreover, unaddressed decay can weaken the structure, compromising safety and creating a less energy-efficient living environment.
When framing a home, an important aspect to consider is that the framing members are properly sided and spaced for support of the barring weight. If compression and tension of the framing members are not taken into consideration, a live load of that area can cause a failure of the framing members.
Task 1: Decay protection inspection essay
When inspecting a new construction for Decay protection in Idaho it is imperative to remember the different seasons that we have. Snow in the winter is always an issue that then turns into water issues come spring when it melts. Ensuring that there is proper protection from the snow and melting snow from allowing moisture into the structure and supports is very important. If there is not proper separation from the ground to the siding for example there is going to be moisture introduced to the structural supports behind the insulation when snow is sitting next to the siding and melting. Also making sure the the drainage is correct around the property so that when the snow begins to melt is very important for making sure there is no moisture intrusion.
Allowable Spans and Material:
The pre-drywall inspection is the last time many of the elements can be seen prior to covering material such as drywall is installed. It is also the best time to make any corrections to the framing with the least amount of destruction and time delay to the building schedule. The investment made for a pre-drywall inspection can save the contractor time and money in possible future repairs and provide the buyer with a well built home.
If a home is not inspected for sufficient allowable span supports there can be major repercussions. The allowable span supports are there to ensure that the house has the correct support in all areas. Especially areas that have large spans that need increased supports like large doors or windows. If these areas are not supported correctly then damage can occur that can be very expensive to repair after the house is completed. If these can be inspected prior to drywall installation then they can be addressed before it becomes harder to do and more expensive.
Task 1:
Clearance, Clarence. Inspecting for proper decay protection on a new build is largely about clearance to grade or exposed ground. Wood framing directly on a concrete or masonry foundations less than 8" from grade needs to be treated. At the exterior, wood siding, sheathing, and framing less than 6" from from grade or less than 2" from concrete surfaces must be treated. In a crawl space, the following must be treated: wood joists closer than 18"; girders closer than 12"; and wood columns closer 8 inches. Failure to have proper treatment in these areas will result in decay issues in a relatively short amount of time.
Task 1 Decay Prevention
Inspecting for decay protection involves going back to the basics and following the IRC; specific guidelines are in place to protect wood and wood-based products in moisture-prone locations, Making sure there is proper drainage and proper clearances and the use of appropriate materials that are decay resistant along with the proper fasteners for material and location.
Failing to properly perform these inspections and identify obvious deficiencies opens the inspector up to liability and a clients home risk of future problems.
Task 2
Inspecting for Termite Protection
Being in Florida it is imperative to have proper termite protection in place as this area is indicated as a very heavy infestation region.
A new home not having the proper termite protection can lead to very costly damages to the home.
During the planning stages of a home determination of what methods of protection will be used and during the inspection determine the proper execution of these methods were completed. This would be the physical barriers, chemical treatments, properly treated or naturally resistant materials. Because this is a Very High infestation probability area verification of proper clearances and proper products are essential to appropriate protection.

Task 1 termites
When reviewing a new deck that is installed, it is important to check that there is no earth wood contact with untreated wood. This would be an obvious mistake in new construction, and would cause the rot of wood and be a avenue for termites.
Tension loads must be considered when viewing floor joints. The wood material for this load must also be known. If you missed this issue, you could have a bowing floor and possibly collapse under high-weight loads.
Checking the allowable spans (maximum distance ) in a home inspection is crucial for ensuring a safe strong home. Different species and products have different allowable spans. An inspection will allow identification that the proper product was used for a particular span, If the wrong materials are used, like using regular wood where you need engineered lumber can be hazardous.
Inspection of allowable span essay: Failing to perform an inspection can lead to structural and safety problems, such as beam, joist or rafter exceeding allowable spans and sagging and uneven floors or even collapse.
Task 1: Decay Protection Inspection
Inspecting for the potential of decay in a new construction consists of checking for termite and moisture mitigation in accordance with the IRC. Ensuring untreated lumber is high enough off the ground, or is pressure treated is important to preventing moisture and WDI intrusion. Checking that hardware is compatible with treated wood is also important.
Task 1. Inspection of allowable spans and material. The structural behavior of any element will depend on its shape and dimensions. Thus, structural beams have a maximum capacity of resistance to transfer loads without deforming, which is considered to establish the separation between the support points. This distance between the support points is known as SPAN and is the free horizontal distance of a beam that can tolerate the maximum allowable deformation to maintain the reliability of the structural design. Maintaining these maximum distances is crucial to achieve the correct transfer of loads to the foundation. The inspector must consider the information tabulated in the building regulations to verify the adequate spacing between the supports available in the structure.
Task 1. Inspection of allowable spans and material
The consequences of not inspecting for proper spans and materials is severe. If a beam or girder is over spanned, it can bend, deflect and even fail causing catastrophic damage and collapse. The same can be said for using a sub-standard material instead of what is required in the IRC. Inspecting for proper spans is critical to determine if a structure was built properly and is safe.

The 2021 International Residential Code provides detailed guidelines on allowable joist spans, which depend on factors such as wood species, grade, size, and load requirements. Joist span tables in the IRC ensure structural integrity by specifying the maximum unsupported distance a joist can safely span under designated loads. For example, a 2x10 joist made from Douglas Fir-Larch under a live load of 40 pounds per square foot may span up to 16 feet, depending on spacing. Proper adherence to these standards ensures a safe and durable structure, preventing issues like sagging or failure. Builders and inspectors rely on these tables to meet code requirements and maintain building safety.
Neglecting to inspect for decay and moisture protection during a home inspection can lead to significant, costly damage. Over time, undetected moisture buildup can foster wood rot, mold growth, and structural weakening, compromising the integrity of a home’s foundation, walls, and roofing. Without proper moisture protection, areas like basements, attics, and crawl spaces are particularly vulnerable to these issues. Homeowners may face expensive repairs, health risks from mold exposure, and a decrease in property value. Preventive inspection can identify early signs of decay, enabling timely repairs that save money and protect the overall safety and longevity of the home.
