A construction site preparation checklist runs in a specific order because each step depends on the one before it: pull permits and confirm zoning, survey the boundaries, mark underground utilities through 811, test the soil, secure environmental permits, screen for hazardous materials, clear and grade, compact the subgrade, install temporary facilities and safety infrastructure, and keep erosion controls inspected until the site is stabilized. Skip a step and you invite stop-work orders, environmental fines, or a foundation poured on soil that cannot hold it. Local rules add to the federal baseline, so verify jurisdictional requirements before breaking ground.
Pull Permits and Confirm Zoning First
Nothing else on the checklist matters if the paperwork isn’t in place. Most jurisdictions require a building permit before any physical work begins, and the application typically asks for the property’s legal description, its tax parcel number, and the construction drawings. Permit fees scale with the estimated value of the work. Zoning clearance is a separate confirmation that your intended use matches the local land-use plan, including density limits, setbacks, and height restrictions.
Building departments generally require the general contractor’s license number and proof of insurance, including workers’ compensation coverage, before issuing the permit. Grading, demolition, and right-of-way work may each need their own permits. Filing everything at once, and confirming approval from every relevant department, avoids weeks of back-and-forth once equipment is scheduled. Working without the right permits triggers stop-work orders and daily fines.
Order a Boundary Survey
A licensed land surveyor establishes the legal boundaries by researching recorded deeds, locating existing monuments, and marking corners with stakes or pins. The survey also identifies easements, rights-of-way, and encroachments that could restrict where you build. The finished plat becomes the reference your design team uses to position the building footprint, setback lines, and drainage features, and the elevations feed directly into the grading plan.
Finding an easement that cuts through your planned foundation is manageable during design. Finding it after the concrete cures is not. Skipping the survey is how projects end up with foundations that cross property lines or driveways that block utility easements, and both are expensive to correct.
Call 811 Before Any Digging
Federal and state law require you to contact 811, the national call-before-you-dig service, so utility companies can mark the approximate locations of buried water, gas, electric, sewer, and telecommunications lines. Technicians typically flag or spray-paint the ground within a few business days. Because the marks are approximate, most states establish a tolerance zone, commonly 18 to 24 inches on each side of the marking, where you must hand-dig rather than use mechanical equipment until the line’s exact position and depth are confirmed.
Hitting an unmarked line exposes you to civil penalties that vary by state plus the full repair cost and any service-interruption damages. A gas strike can injure or kill workers. Treat every tolerance zone as if the line is exactly where the backhoe wants to go.
Get a Geotechnical Report
A geotechnical engineer drills soil borings at multiple locations to evaluate what your foundation will be sitting on. The borings measure load-bearing capacity, moisture content, depth to bedrock or groundwater, and the presence of unstable layers like organic material or expansive clay. The resulting report tells your structural engineer whether the site can support a standard slab-on-grade, whether deep foundations like piers or caissons are needed, or whether the soil requires stabilization before any concrete is placed.
The report also flags high water table conditions that may require dewatering. Under the EPA’s Construction General Permit, uncontaminated groundwater pumped from foundations and trenches is an authorized discharge, but you must meet the permit conditions, and contaminated water may require a separate discharge authorization.1Environmental Protection Agency. Inspection and Monitoring Guide for Construction Dewatering
Handle Environmental Permits
Under the Clean Water Act, any construction activity that disturbs one acre or more of land requires a National Pollutant Discharge Elimination System (NPDES) permit for stormwater discharges. Smaller projects still trigger the requirement if they are part of a larger common plan of development that will ultimately disturb one acre or more.2US EPA. Stormwater Discharges from Construction Activities Subdivision builders often assume their individual lots are too small to matter and get caught by that second rule.
The permit requires a Stormwater Pollution Prevention Plan (SWPPP), which identifies potential pollutant sources, describes the erosion and sediment controls you will install, and names the person responsible for inspections and maintenance. Typical controls include silt fences along the perimeter, sediment basins or traps at discharge points, and stabilization measures like erosion blankets or temporary seeding on exposed slopes. The SWPPP must be updated whenever site conditions change significantly.
Wetlands and Section 404
If your site contains wetlands, streams, or other waters of the United States, Section 404 of the Clean Water Act requires authorization from the Army Corps of Engineers before you discharge any fill material, permanent or temporary, into those areas.3US EPA. Permit Program Under CWA Section 404 The Corps evaluates whether a less damaging alternative exists and whether you have minimized and compensated for unavoidable impacts. A wetland delineation done before design can save months by identifying problem areas early enough to shift the site plan.
Endangered Species Screening
Coverage under the EPA’s Construction General Permit also requires screening for threatened and endangered species and critical habitats within the project’s action area. The action area extends beyond the construction footprint to include everywhere stormwater flows from the site to receiving waters. You identify potential species impacts using the U.S. Fish and Wildlife Service’s IPaC tool and, where applicable, the National Marine Fisheries Service’s ESA Section 7 mappers. The screening determines which eligibility criterion you qualify under, and that determination is part of the permit application.4US EPA. Construction General Permit Threatened and Endangered Species
Screen for Hazardous Materials Before Demolition
Asbestos carries the strictest timing rule. Under the EPA’s National Emission Standards for Hazardous Air Pollutants, you must notify the relevant authority at least 10 working days before beginning demolition of a structure that contains asbestos, or before stripping or removing asbestos-containing material during renovation.5eCFR. 40 CFR Part 61 Subpart M – National Emission Standard for Asbestos There is no shortcut. Demolishing a building without the required survey and notification can result in enforcement actions that dwarf the cost of proper abatement.
Lead-based paint, mercury-containing devices, chemical solvents, and treated lumber are other materials commonly encountered during demolition. Under the Resource Conservation and Recovery Act, any business generating hazardous waste must determine whether the waste qualifies as hazardous through testing or process knowledge. Federal regulations divide generators into three categories by monthly volume: very small quantity generators producing 100 kilograms or less, small quantity generators between 100 and 1,000 kilograms, and large quantity generators at 1,000 kilograms or more per month.6US EPA. Categories of Hazardous Waste Generators Each category has different storage time limits, labeling requirements, and reporting obligations, and hazardous waste cannot go to ordinary construction debris landfills.
Clear, Demolish, and Grade
Clearing removes trees, brush, stumps, and root systems from the building footprint and surrounding work areas. Demolition takes down existing structures. Both generate debris that must go to properly permitted disposal facilities. Organic material left underground can decompose and create voids that cause future settling, so thorough grubbing of root systems matters more than it looks.
Grading reshapes the cleared land to match the elevations on the construction drawings, with the primary objective of directing water flow away from the future foundation and toward designated drainage features. Engineers verify that finished grades match the design within tight tolerances, sometimes fractions of an inch for critical elevations like foundation tops and drainage invert points. Rough grading establishes the overall landform; fine grading later prepares the exact subgrade surface that will receive foundations, slabs, or paving.
Compact the Subgrade and Test It
Graded soil must be compacted to a specified density before it can support structural loads. The standard approach uses a Modified Proctor test to establish the maximum achievable density for the soil type, and specifications then require compaction to a percentage of that maximum, commonly 95 percent for structural fills beneath foundations. An independent testing firm takes field samples and nuclear density readings to verify that each lift meets the specified percentage, and lifts that fail get reworked before retesting.
This is a step where cutting corners produces invisible problems. Soil that passes compaction testing supports the building as designed. Soil that does not will settle differentially, crack foundations, and misalign door frames for years. The testing reports become part of the project record and are often required by the building inspector before foundation work can begin.
Set Up Temporary Site Infrastructure
Before crews can work productively, the site needs fencing, sanitation, power, water, and safety signage. Perimeter fencing keeps unauthorized people away from open excavations, heavy equipment, and stored materials. Height and material specifications vary by jurisdiction. Chain-link is common, though some jurisdictions require solid fencing or additional screening.
OSHA requires employers to provide toilet facilities for construction workers. The minimum is one toilet for 20 or fewer employees, one toilet and one urinal per 40 workers for crews of 20 or more, and one toilet and one urinal per 50 workers once the workforce exceeds 200.7eCFR. 29 CFR 1926.51 – Sanitation Facilities that become unsanitary are considered unavailable under OSHA’s interpretation, so a dirty portable restroom does not count toward compliance even if it is physically on the site.8Occupational Safety and Health Administration. Whether Toilets at a Construction Jobsite Must Be in a Sanitary Condition
Temporary electrical service, typically through a metered construction pole, powers tools, lighting, and heating. A temporary water meter supplies water for dust suppression, concrete curing, and sanitation. Designated access points let delivery trucks enter without destroying adjacent curbs, sidewalks, or landscaping, and gravel construction entrances at those points reduce mud tracked onto public roads, which is both practical and typically required by the stormwater plan.
Signage and PPE
OSHA requires specific signage to warn workers and visitors of hazards. Danger signs are used where an immediate hazard exists, caution signs for potential hazards, and construction areas near traffic must be posted with signs and devices conforming to the Manual on Uniform Traffic Control Devices.9Occupational Safety and Health Administration. Accident Prevention Signs and Tags Signs must be visible whenever work is being performed and removed when the hazard no longer exists.
OSHA’s general safety provisions also require a fire protection and prevention program throughout all phases of construction, first aid services and medical care access, and appropriate personal protective equipment.10eCFR. 29 CFR Part 1926 Subpart C – General Safety and Health Provisions Most sites treat hard hats, high-visibility vests, eye protection, and steel-toed boots as a baseline, adding fall protection and other equipment as the scope demands.
Keep Erosion Controls Inspected
Installing silt fences and sediment traps is only the beginning. Many state permits require inspections at least once every seven days, or once every 14 calendar days plus within 24 hours of a storm event that produces a discharge. The specific frequency depends on your state’s permit, but the EPA’s guidance sets the general framework.11Environmental Protection Agency. Stormwater Best Management Practice – Erosion and Sediment Control Inspection and Maintenance
Silt fences should be repaired or replaced as soon as damage is found, and accumulated sediment must be removed before it reaches half the above-ground height of the fence. Inspect all controls within 48 hours after significant rain and document the condition of each. Inspection records belong in the SWPPP and must be available for regulator review. A pattern of missed inspections is one of the most common triggers for stormwater enforcement actions.
Line Up Insurance Before Mobilization
Most lenders and many building departments require proof of insurance before issuing permits or releasing construction loan draws. General liability covers third-party injuries and property damage. Workers’ compensation, required in nearly every state, covers employees injured on the job. Builder’s risk insurance, sometimes called course-of-construction coverage, protects the structure and permanently installed materials against fire, theft, vandalism, weather damage, and similar losses during construction. Banks frequently require builder’s risk as a condition of the loan, and government contracts may mandate it. Bind coverage before mobilization; a policy is much harder to arrange after a loss has already occurred.
