Who’s Doing the Work on Your Rebuild? Why Licensing and Documentation Matter in Altadena

Rebuilding a home involves a long list of specialized trades, and much of the most important work happens before there is much to see above ground.
That came up recently in an onsite conversation shared by HPP CARES with Jerry Sprague of Diggin Cali, one of the trade partners working with Remington Rebuilds in Altadena. Jerry was discussing excavation and over-excavation work and raised an important point for homeowners: who performs the work — and whether they are properly qualified and licensed for that scope — matters.
As rebuilding moves forward throughout Altadena, it is a good reminder that a faster process should still be a careful one.

Different Work Requires Different Expertise
A homebuilder coordinates the overall construction of a home, but many individual stages are completed by specialty trade partners.
Excavation and grading are good examples.
In California, the Contractors State License Board defines a C-12 Earthwork and Paving Contractor as a contractor whose work includes excavation, grading, trenching, backfill and other earthwork. An A General Engineering Contractor classification also encompasses earthmoving, excavating and grading work.
For homeowners, the important takeaway is not necessarily memorizing license classifications. It is knowing that specialized construction work should be performed by contractors who are appropriately licensed and qualified for the work they are doing.
A good builder should know who is working on your property, understand the scope each trade is responsible for and verify that the right professionals are in place.

Why This Matters Before the Foundation
We recently shared a closer look at what happens before a foundation is poured, including excavation, over-excavation, backfill and compaction testing.
These early stages can be easy to overlook because much of the work eventually disappears beneath the home. But the foundation depends on the conditions and preparation of the soil below it.
Depending on the property and engineered requirements, that process may involve a soils engineer, excavation contractor, compaction testing, inspections and documentation before construction can move forward to the next stage.
Each property is different, and not every rebuild will require exactly the same site work. Understanding the existing conditions on the lot is an important part of determining what engineering, site preparation and construction requirements may apply.
Permitting Can Move Faster. The Work Still Has to Be Done Correctly.
Los Angeles County has introduced resources intended to help Eaton Fire homeowners move more efficiently through the rebuilding process.
That is welcome progress.
But streamlining portions of permitting does not mean eliminating the building, fire, health and safety requirements that apply to a rebuilt home. Even qualifying like-for-like rebuilds must comply with current Building, Fire, and Health and Safety Code requirements.
Construction still moves through required reviews and inspections along the way.
The goal is not to make rebuilding unnecessarily complicated. It is to make sure that each stage is ready for the one that follows.

What Can Homeowners Ask Their Builder?
You do not have to become a construction expert to ask good questions.
As your rebuild moves into construction, consider asking:
Who will be performing the major scopes of work on my home?
Does my builder work with established trade partners?
How are contractor licenses and qualifications verified?
What engineering, testing or documentation is required for my property?
What inspections need to happen before the project can move to the next stage?
Who is responsible for coordinating those inspections and keeping the appropriate documentation?
Your builder should be able to explain not only what is happening on your property, but also who is responsible for it and what needs to happen before the project moves forward.
Licensing and trade qualifications are also part of the larger question of what to look for in a rebuilding partner.

The Work You Don’t See Still Matters
Rebuilding a home is a sequence. Excavation supports the foundation. The foundation supports the framing. The framing makes way for the systems and finishes that eventually turn a construction site into a home. Learn more about our rebuilding process.
Doing each stage properly helps protect everything that comes after it.
