A foundation inspection should leave you knowing more than when you started. Chula Vista Structural inspects foundations for homeowners, buyers, sellers, and small landlords across the city. We look, measure, and write down what we find in language you can share with family, a lender, or your HOA. If the findings call for engineering, we coordinate with licensed engineers as needed.
Common reasons for a visit
- During escrow. A general home inspector wrote “recommend evaluation by a foundation specialist,” and now the clock is running.
- Getting ready to list. No surprises from the buyer’s side.
- Something changed. A crack you hadn’t seen, a door that started rubbing, and you want to know if it’s serious.
- HOA questions. A slope, wall, or drainage swale near your home looks wrong, and you need facts before you talk to the association. See HOA foundation concerns.
- Before a remodel. You plan to add a room, open a wall, or cut into a slab.
- Rental property. A landlord with an older house wants a baseline on record.
Where we fit next to your home inspector
Think of it as a ladder. Your general home inspector goes through everything from the roof to the water heater in one visit. Spotting a foundation sign and writing “refer to a specialist” is that inspector doing the job right. We are the next rung up: one system, studied closely, with measurements.
Above us are engineers. Engineers can do the math and stamp a repair drawing, and that’s the structural engineer’s lane. A geotechnical engineer tests the ground itself by drilling and sending samples to a lab, and on clay or canyon fill that soil work can matter a lot. When the situation calls for that, we tell you and coordinate with licensed engineers as needed.
What we check
What it sits on. A raised wood floor, a regular slab, or a post-tension slab. On newer homes in EastLake, Otay Ranch, or San Miguel Ranch, we look for stamps or markings in the garage and at the slab edge that suggest post-tensioning. That changes what repairs are safe.
Floor levels. We take elevation readings across the house (more on this in uneven floors). A pattern tells us much more than one low spot. A floor that is high in the middle and low at the edges points one way. A floor that drops toward a canyon side points another.
Crack map. Every crack we find, inside and out, gets marked on a floor plan. We note width, direction, and whether one side is offset from the other.
Doors and windows. Which ones stick, and whether they line up with the floor pattern.
Drainage. Where the downspouts empty, which way the ground slopes, how close the sprinklers spray to the foundation. On clay soil this is often the biggest clue.
Site conditions. Nearby slopes, retaining walls, canyon edges, and whether the lot looks cut, filled, or both.
Under the floor. On raised homes we crawl it: supports, beams, damp soil, rot, and whether bolts tie the house down.
The write-up
After the visit, it all goes on paper with pictures. The report is split into three parts on purpose. Part one is only what we observed and measured. Part two is our read on the cause. Part three lists repair options. A buyer, a seller, or an HOA board can take part one as plain fact without our opinions mixed in.
When a repair makes sense, the report names the next step, such as crack repair, settlement repair, or drainage work. When the cause can’t be pinned down without testing, it says that too. “This needs a soils engineer” is a better answer than a guess.
Chula Vista details we pay attention to
Two kinds of neighborhoods. West-side ZIPs 91910 and 91911 have a median build year in the early 1970s. East-side ZIPs 91913, 91914, and 91915 have a median build year around 2004 to 2006 (Census ACS 2024). Our checklist shifts with the house. Older homes get more attention to framing, bolting, and footings. Newer homes get more attention to slab behavior and drainage.
Clay and grading. Chula Vista’s grading code requires expansive soil near the surface in building areas to be removed and replaced unless a soils engineer designs around it. So we do not assume a newer house sits on raw clay. We look for evidence either way.
Jurisdiction. Bonita and Sunnyside addresses are County, not City. If our findings lead to repairs, the permit path depends on which side of that line you are on.
Inspections during escrow
Escrow timelines are short. Tell us your contingency date when you reach out. We will be clear about how soon we can visit and when the written summary will be ready. We describe conditions as we find them. We do not write reports to help a deal close or fall apart.
Questions people ask
How long does an inspection take?
It depends on the size of the house and whether there is a crawl space. We give you a time estimate when we schedule.
Should I get an engineer instead?
If the City will need stamped plans, or the soil is in question, yes, eventually. An inspection first can tell you whether you need one, and what to ask when you call.
Can you tell if my house has a post-tension slab?
Usually there are telltale marks. Original plans or builder records settle it. Until it is confirmed, nobody should drill or cut the slab.
Does a crack in my garage floor mean the foundation is failing?
Not by itself. Concrete shrinks as it cures, and a bare garage slab shows that more plainly than a finished floor. Pay attention if one side of a crack sits higher than the other or the crack keeps opening. What foundation cracks mean walks through those patterns.
