Footings sit below the visible parts of a building, but they carry a critical job. They spread structural loads into the soil and support foundation walls, columns, posts, and other elements. Our residential foundation footing basics guide explains what happens below grade.
At The Legend Concrete & Construction, we bring more than 13 years of experience to concrete and construction work in the Dothan area. We serve both residential and commercial customers with licensed and insured service, free estimates, and 24-hour availability when urgent construction issues arise.
What Does a Concrete Footing Actually Do?
A footing creates a wider bearing surface beneath a foundation or support, spreading wall or column loads across more soil.
Proper footing design helps provide a stable base. Dimensions depend on structural loads, soil, foundation type, and applicable code.
Footing Depth for Alabama Homes Is Not One Fixed Number
There is no universal footing depth for every Alabama project. Depth depends on local code, soil, grade, erosion risk, structural loads, and what the footing supports.
Dothan has a mild winter climate, but footings still need suitable bearing soil and must meet approved plans and local code.
Conditions That Can Change Footing Depth
- Soft or disturbed soil near the surface
- Sloped building sites
- Recent fill material
- Heavy structural loads
- Drainage or erosion concerns
- Changes in finished grade
- Engineering requirements
Footing Size and Layout by Project Type
| Project | Main Footing Concern | What Must Be Planned |
|---|---|---|
| New home | Continuous wall loads | Width, depth, reinforcement, and elevations |
| Room addition | Connection to existing foundation | Matching loads and avoiding uneven movement |
| Porch or covered patio | Point loads at posts | Individual footing size and location |
| Commercial structure | Higher or concentrated loads | Engineered footing and inspection requirements |
| Exterior column | Load concentrated in a small area | Centering, reinforcement, and bearing soil |
Why Foundation Footing Layout Must Be Accurate
Footing layout establishes the structure’s position. A small error underground can create larger alignment problems later.
Before concrete is placed, verify dimensions, corners, elevations, setbacks, and foundation locations. Approved plans or engineering documents should guide larger projects.

Concrete Footing Reinforcement
Reinforcement helps concrete handle tensile forces. Rebar size, spacing, position, lap lengths, and concrete cover should follow the approved design and code.
Adding steel without a plan is not a substitute for correct footing dimensions or suitable soil.
Common Mistake: Reinforcement placed directly on the soil may not end up in the intended position inside the concrete. Rebar should be supported and placed according to the project requirements before the pour.
Soil and Water Matter Before the Pour
Dothan’s rainfall makes site drainage important before the foundation is built. Loose soil, standing water, or disturbed material can reduce support in a footing trench.
The excavation should be checked before concrete placement. Soft spots, excessive water, or unexpected soil conditions may need correction before the project continues.
Watch for These Site Problems
- Standing water in footing trenches
- Loose soil falling from trench walls
- Organic material at bearing level
- Over-excavated areas filled without proper correction
- Runoff entering the foundation area
Dothan Permits and Foundation Inspections
The City of Dothan requires permits for applicable residential and commercial construction, and its residential guidance includes foundation and floor-slab inspections.
Footing work should follow approved plans and the inspection schedule. Do not place concrete before any required footing or foundation inspection.
Dothan’s permit system also allows residential and commercial permit applications online. Because requirements vary by project, confirm the permit, plan, and inspection needs before excavation begins.
Why Commercial Footings May Need More Planning
Commercial buildings can place larger loads on foundations. Plans may call for wider footings, deeper excavation, larger reinforcement, grade beams, or column pads.
Residential projects can also require engineering when soil conditions, spans, additions, or unusual structural loads fall outside standard construction details.
What Should a Footing Installation Estimate Cover?
A footing estimate should describe excavation, dimensions, forming, reinforcement, concrete placement, access, cleanup, and any work that depends on plans, engineering, or inspections.
At The Legend Concrete & Construction, we provide free estimates and work with residential and commercial property owners. Our regular hours are Monday through Saturday from 6:00 a.m. to 8:00 p.m. We also maintain 24-hour availability for urgent service needs.
Frequently Asked Questions
How deep should footings be in Dothan, Alabama?
Depth depends on the structure, soil, grade, approved plans, and code requirements. A contractor should evaluate the project instead of relying on one standard depth.
Do concrete footings always need rebar?
Reinforcement requirements depend on the footing design, structure, loads, and applicable code. When rebar is required, its size and placement should follow the approved design.
Can concrete be poured if the footing trench has water?
Standing water and soft soil should be evaluated before placement. The bearing surface needs to meet project requirements so the footing starts on suitable support.
Does Dothan inspect residential foundation footings?
Foundation work is included in the city’s residential inspection process for permitted construction. Required inspections should be completed before concrete placement when applicable.
Do you provide footing estimates for commercial projects?
Yes. At The Legend Concrete & Construction, we provide free estimates for residential and commercial footing and foundation concrete projects in Dothan and nearby areas.
Build the Foundation From the Ground Up
Footings are difficult and expensive to correct after the rest of the structure is built. Careful layout, solid bearing conditions, proper reinforcement, and inspection coordination are worth getting right from the beginning.
