Planning an addition, ADU, patio cover, or retaining wall? The footing is the part you will never see - and the part your whole investment depends on. We pour footings in Arcadia that are permitted, inspected, and built for local soils and seismic conditions.

Concrete footings in Arcadia are the buried concrete base that holds up walls, room additions, patio covers, ADUs, and retaining walls - most residential footing projects take one to three days of active work, with the concrete ready to build on in about seven days. A properly poured footing, set to the right depth and reinforced with steel, keeps the structure above it stable through California soil movement and seismic activity.
Arcadia homeowners need footing work most often when adding a room, building a detached ADU, installing a patio cover, or replacing a retaining wall on a sloped lot. Every one of these projects in Arcadia requires a city permit, a pre-pour inspection, and footings built to current California code - which includes seismic reinforcement requirements that older homes in this area often do not meet. Getting the footing right the first time is almost always far cheaper than repairing a failing structure later.
Footing work often connects to larger structural projects. If your addition also needs a full slab, our foundation installation service covers the complete foundation system, including footings, from a single crew.
Any structure attached to your home or built above a certain size in Arcadia requires new footings as part of the permitted work. California has made ADU construction much easier, and Arcadia has processed a significant number of them - but every ADU needs proper footings before framing can begin. If you have a general contractor lined up and the plans show concrete work before framing, that is the footing phase.
Diagonal cracks running from the corners of windows or doors near an older addition or outbuilding often signal that the footing beneath it has shifted or settled. In Arcadia's variable soils, this kind of movement is not unusual in structures built in the 1960s or 1970s without current reinforcement standards. A crack that is growing or wide enough to fit a coin is worth having a professional assess before the problem gets worse.
When a footing shifts, the frame of the structure above it shifts too - and the first place you usually notice it is a door or window that no longer opens and closes the way it used to. This is especially common in Arcadia homes where additions were built decades ago under older standards. It does not always mean the footing has failed, but it is a signal worth investigating before further movement occurs.
Arcadia has significant grade changes in its hillside neighborhoods, and fences or retaining walls built on slopes need footings that go deeper and carry more reinforcement than a flat-yard fence. If your existing fence is leaning, pulling away from posts, or showing cracks at the base, the footing may have been undersized for the soil pressure it holds back. Replacing the visible structure without addressing the footing produces the same failure again.
Our footing work covers the full process from permit application through the city inspection and final handoff. We dig to the depth specified in your approved plans, set wooden forms to shape the pour, place steel reinforcing bars to meet California seismic requirements, and arrange for the city inspector to review the work before a single yard of concrete goes in. That pre-pour inspection is the checkpoint that confirms everything is correct while it can still be fixed - not after it is buried.
For projects in Arcadia where soil conditions vary - including properties where a crew may hit caliche, the hard calcified layer common in parts of the San Gabriel Valley - we flag this upfront in our estimate rather than surprising you with a change order mid-project. When your footing work is part of a larger scope, we coordinate with foundation installation or foundation raising work seamlessly under one project.
For homeowners expanding living space - sized and reinforced to support the full load of the new structure.
For detached or attached accessory dwelling units - engineered to current California code and city-inspected before the pour.
For covered outdoor structures - placed at the required depth for Arcadia's soil conditions and seismic zone.
For grade changes and sloped lots - deeper and more heavily reinforced than flat-yard applications.
Arcadia sits on alluvial soils deposited by the San Gabriel River - soils that shift, compress, and expand depending on moisture levels. In some areas, a dense caliche layer sits below the surface, making digging harder and slower. Add to that the seismic reality: Arcadia is near the Sierra Madre and Raymond fault systems, and California building code requires footings here to include specific amounts of steel reinforcement and meet depth and width standards designed to survive significant ground movement. For homeowners with 1940s through 1970s housing stock, original footings were built to older, lower standards - a fact that comes up often when adding onto these homes or when structures on the property show signs of settlement.
We serve Arcadia and surrounding communities throughout the San Gabriel Valley. Homeowners in Pomona and Glendora face similar soil and seismic considerations. For those planning an ADU, the USGS Earthquake Hazards Program publishes maps showing exactly which fault systems affect Arcadia and the surrounding valley.
We respond within 1 business day and come to your property before giving you a number - footing work is hard to price accurately without seeing the soil, access, and scope. Expect the estimate visit to take 20 to 45 minutes. We flag known risk factors like caliche in the estimate, not after work begins.
We pull the building permit from the City of Arcadia before any digging starts. Larger projects - ADUs, significant additions, retaining walls - may require stamped engineering drawings before the city approves the permit. We handle the application; you make sure we are doing it.
The crew digs to the depth in your approved plans, sets wooden forms, and places steel reinforcing bars. Before the pour, a city inspector visits to confirm depth, width, and steel placement all match the approved plans. Nothing gets buried until that inspection is done.
Concrete is poured once the inspection clears - usually delivered by ready-mix truck and directed into the forms by the crew. We apply a curing compound or cover to manage moisture loss, especially important in Arcadia's summer heat. The footing is ready to build on in about 7 days. You get a copy of the closed permit for your records.
We come to the site, walk you through what the job involves, and give you a written quote - no pressure, no obligation, and we handle the permit.
(626) 898-6986Every footing project we handle in Arcadia includes the pre-pour inspection. A city inspector checks depth, width, and steel placement before concrete goes in. This is the step that protects you - because once the concrete is poured, what is wrong cannot be fixed cheaply.
Arcadia sits near active fault systems and California code reflects that. We build every footing with the steel reinforcement and dimensional requirements the city inspector will be checking - not to a lower standard that might pass a visual look but fail when the ground moves.
We work regularly across Arcadia and surrounding cities. Local experience matters for footing work because Arcadia inspectors have specific expectations, and local soil conditions - including caliche - are not surprises to us. Contractors who rarely work here often miss these details.
Unpermitted structural work is one of the most common issues Arcadia homeowners discover during escrow. When your footing work is permitted and inspected from the start, that documentation lives with your property record permanently - protecting your investment regardless of when you sell. The American Concrete Institute publishes guidance on why footing standards matter at concrete.org.
The footing is the one part of your project that you will never be able to fix cheaply once the structure is built on top of it. Every job we do starts with that reality - and it shows in how we approach the permit, the pre-pour inspection, and the pour itself.
