Key takeaways
- Call 811 before any digging so underground utilities are marked.
- Many structures need permits, including taller walls, fireplaces, chimneys and structural work.
- Neighborhood associations may add their own rules.
- Cutting masonry and concrete makes dust that should be controlled.
Call 811 first
Before digging for footings, posts, trenches or even a shallow base, call 811 so buried gas, power, water and communication lines are marked. It is free to request and it is the law in Tennessee. Damaging a line can be dangerous and expensive.
Your mason may make the request, but the homeowner should know it has been done and respect the marks.
Permits and inspections
Permits are usually needed for structures, fireplaces and chimneys, taller retaining walls, gas lines and some outdoor kitchens. In Nashville, the Codes Department handles building permits and inspections for Davidson County, and neighboring counties have their own offices.
Ask early, because permits and engineering can take time. A good contractor helps you find out what applies.
Checking a contractor
Ask for references, photos of past work and a clear written scope. Tennessee has contractor license requirements that vary with the size and type of the job, and the state offers an online lookup. Ask whether the work needs a specialist trade, such as gas or electrical, and who will do it.
Be wary of anyone who asks for large payments up front or who cannot explain how they will handle drainage, bases and flashing.
Dust, safety and neighbors
Cutting brick, block, stone and concrete creates fine dust that contains silica, which is harmful to breathe. Professional crews use water, vacuums and respirators to control it, and you should keep children and pets away from the work area.
Good crews also protect landscaping, keep the site tidy and let neighbors know about noise and deliveries.
