Development projects fail their timelines in predictable ways. After working with developers, landowners, and businesses navigating the permitting process across multiple states, we see the same mistakes surface again and again. None of them are inevitable. All of them are avoidable with the right legal groundwork in place before you break ground.
Here are five permitting pitfalls that routinely stall projects, and what you can do to stay ahead of each one.
1. Starting Construction Before All Permits Are in Hand
This sounds obvious, but it happens more often than you might expect. A project is behind schedule, a contractor is ready, and one permit is still pending. The decision to start anyway can result in stop-work orders, fines, mandatory restoration of disturbed areas, and in some cases, denial of the outstanding permit because work began without authorization.
Regulatory agencies have long memories. A stop-work order on one project can complicate permitting relationships for years. The cost of waiting for proper authorization is almost always lower than the cost of getting caught without it.
A single stop-work order can delay a project by months and add tens of thousands of dollars in compliance costs. Proper permit sequencing before mobilization is always worth the wait.
2. Failing to Account for Environmental Review Timelines
Federal and state environmental review processes operate on their own timelines, and those timelines do not bend to project schedules. The National Environmental Policy Act (NEPA), state equivalents, and agency-specific review requirements can add months or years to a project, particularly when the review uncovers issues that require mitigation.
The mistake most developers make is treating environmental review as a box to check rather than a process to manage. Reviews that are engaged proactively, with legal counsel helping to shape the scope and quality of submissions, move faster and produce fewer surprises than reviews that are treated as administrative formalities.
Early identification of potential environmental issues allows you to design around them or develop mitigation plans before you are in front of an agency. Discovering those issues mid-review is much more costly.
3. Missing Public Comment Periods
Many permits, particularly those involving zoning changes, conditional use approvals, and environmental permits under federal and state law, require public notice and a comment period. These periods are not just procedural formalities. Comments from neighbors, advocacy groups, or competing interests can influence permit conditions, require additional studies, or in some cases result in denial.
Developers who are not monitoring the public comment process cannot respond to concerns before they become conditions or objections. Legal counsel with experience in permitting can track comment periods, identify who is likely to comment and why, and prepare responses that address concerns directly rather than letting them accumulate into a formal opposition record.
Public participation also creates appeal rights for third parties. Understanding who might appeal a permit decision, and engaging them before they do, is one of the most underused tools in development law.
4. Inadequate Site Assessments Before Acquisition or Application
Buying land or filing a permit application without a thorough understanding of environmental conditions on the site is one of the most expensive mistakes in development. Phase I and Phase II environmental site assessments exist for exactly this reason, but developers sometimes skip or minimize them to save time or money at the front end of a project.
Discovering contamination, wetlands, protected species habitat, or floodplain issues after acquisition locks you into a site with complications that may be impossible or prohibitively expensive to resolve. The same discovery during permitting can halt a project indefinitely while remediation, mitigation, or redesign is worked out.
A thorough site assessment before you commit to a property or a project design is the single most cost-effective environmental legal step a developer can take.
5. Misunderstanding Jurisdictional Overlaps
Development projects frequently require permits from multiple agencies at the federal, state, and local levels. Army Corps of Engineers wetlands permits, state water quality certifications, local zoning and building permits, fire marshal approvals, and utility easements can all be required for a single project. Each has its own application requirements, timelines, and standards.
The mistake is treating these as independent processes. In reality, the conditions attached to one permit can affect the design requirements for another. An Army Corps permit condition requiring a specific buffer width, for example, may conflict with local setback requirements or reduce the buildable area below what makes the project viable.
Understanding how permits interact, and sequencing applications strategically, can save months of back-and-forth between agencies. Legal counsel who works across all relevant regulatory frameworks can map the full permitting landscape for a project before applications are filed, surfacing conflicts early enough to design around them.
What Good Permitting Looks Like
Projects that move through the permitting process efficiently share a few common characteristics. They begin legal review before site selection is finalized. They invest in thorough environmental due diligence up front. They engage counsel who understands the specific regulatory landscape for the project type and location. And they build realistic timelines that account for agency review periods rather than treating permits as a formality that will resolve itself.
Environmental and land use law is not a back-office function. It is a front-end project management discipline, and the developers who treat it that way consistently outperform those who do not.
