Many new concrete foundations need a building permit, and some also need an engineer’s design, depending on the type of structure, its size, the site conditions and local requirements. The safest approach is to confirm what applies with the local building department before any work begins.
Foundations carry the weight of everything above them, so they are reviewed more closely than many other concrete projects. The exact requirements depend on the project, which is why they should be checked early.
Why Foundations Are Reviewed
A foundation supports the structure, resists frost and moisture and must work with the soil on the site. Mistakes are hard and costly to fix once a building is in place.
Permits and inspections help confirm that the foundation follows the codes that apply. Inspections may happen at certain stages, depending on the jurisdiction and the project.
Lenders, insurers and future buyers may also ask whether permitted work was inspected, so following the process can matter long after the concrete is placed.
When an Engineer May Be Involved
Some foundations can be built from standard designs allowed by the building code. Others need an engineer, such as foundations on challenging soil, steep or unusual sites, larger or heavier buildings, commercial projects or designs outside standard code options.
An engineer may review soil information, loads and site conditions to design footings, walls and reinforcement for that project. That design is specific to the site and should not be swapped for general rules.
Additions to existing homes can raise their own questions, such as how the new foundation will meet the old one. These details are often part of the design review.
Local Requirements in Kalamazoo
Requirements can differ between the City of Kalamazoo and surrounding townships. For properties in the city, the City of Kalamazoo building permit information is a helpful starting point. That page notes that a building permit is needed for structural work.
For properties outside the city, check with the township or county that handles building permits for that location.
Planning Steps
Before construction, gather plans, site information and any engineering documents the project needs. Ask who is responsible for pulling permits and scheduling inspections, and build time for review into the schedule.
Michigan weather can also affect timing, since foundation work needs suitable conditions. Planning permits early can help keep the project on track for the building season.
This article is general information and not legal or engineering advice. Requirements should be confirmed for each specific project.
Keep copies of approved plans, permits and inspection records. They can be helpful for future work, insurance questions or a sale of the property.
