1. Submitting Incomplete or Outdated Property Information
One of the biggest reasons for permit rejection is missing or incorrect paperwork. This includes poorly drawn or outdated site plans, missing floor plans, or incorrect property information.
How to Avoid It
Use professionally drafted, GIS-based site plans that include all required features like property lines, structures, setbacks, and lot dimensions. Explore our Plans & Pricing page to choose the right option.
2. Not Understanding Local Permit Requirements
Each city or county has its own rules—and assuming “one-size-fits-all” leads to unnecessary rework. For example, a swimming pool permit in Florida might require tree impact documentation, while a garage addition in Texas might require detailed setback overlays.
Tip
Always review your local building department’s checklist, or consult with a planner. We also recommend visiting the National Association of Home Builders for broader construction regulations by region.
3. Ignoring Zoning and Land Use Restrictions
Building in the wrong zoning district, exceeding height limits, or encroaching on easements can halt your permit altogether. Many applicants overlook this crucial step.
How to Avoid It
Check your zoning classification and allowable uses before submitting your plan. We can include zoning-compliant features in your site plan if noted during your custom quote request.
4. Choosing the Wrong Type of Site Plan
A basic site plan may be sufficient for a small shed, but if you’re building an ADU, installing a driveway, or subdividing property, you’ll need more detail.
Tip
Our Advanced and Elite plans are designed for larger or more regulated projects—and include setbacks, easements, and topography when required.
5. Skipping Pre-Application Consultations
Many municipalities offer pre-application meetings that can save you time and money by identifying issues early.
Why It Matters
You can avoid multiple rounds of costly revisions by getting expert feedback in advance. Use it to clarify expectations around environmental impact, utilities, and fire code access.
6. Underestimating Permit Timelines
Some permits are issued in 5 days. Others? 5 months. Failing to plan realistically can delay your entire project.
Tip
Always pad your timeline by 2–3 weeks to allow for revisions, especially if you’re in a busy jurisdiction. Ask your planner directly for an estimated review cycle.
7. Starting Work Without a Permit
This is the most expensive mistake. If caught, you could face fines, stop-work orders, or be forced to tear down completed work.
⚠️ Reminder
Always wait until your permit is officially approved and in hand before beginning any construction.
8. Submitting DIY or Hand-Drawn Plans
While tempting to save money, most building departments do not accept hand-drawn plans, especially if they’re not to scale or lack necessary zoning info.
Pro Tip
Let professionals handle it. Our permit-ready site plans include parcel ID, rooflines, setbacks, and GIS-verified layouts that align with local standards. Learn more on our Site Plan Services page.
9. Not Accounting for Environmental or Historic Regulations
If you’re near wetlands, heritage properties, or protected zones, you’ll need additional documentation like impact reports or architectural compatibility statements.
What To Do
Check your local environmental and historic preservation office requirements, or start with a site assessment tool from the EPA.
10. Not Hiring the Right Professionals
Many delays stem from unclear communication, incorrect plans, or missing technical input. A strong team—including a drafting expert, architect, or civil engineer—can help you avoid these missteps entirely.

Frequently Asked Questions About Building Permits and Site Plan Submissions
❓1. What documents are typically required for a building permit application?
Most building departments require a site plan, floor plan, elevation drawings, and sometimes additional documents like engineering reports, zoning compliance forms, or environmental assessments. Submitting a complete package is crucial to avoid delays or rejections.
❓2. Can I submit a hand-drawn site plan for a building permit?
In most jurisdictions, hand-drawn or unscaled site plans are not accepted. Instead, you should submit a professionally drafted site plan that includes key elements like property lines, existing structures, setbacks, and dimensions. Learn more on our Site Plan page.
❓3. How long does it take to get a building permit approved?
Approval times vary based on your local jurisdiction, the complexity of your project, and whether revisions are needed. While simple permits may be processed in a few days, others can take several weeks or months. Planning ahead is key.
❓4. What happens if I start construction before getting a permit?
Starting work without an approved permit can result in fines, stop-work orders, or even demolition of the work already completed. It’s important to wait until your permit is fully approved before beginning construction.
❓5. How do I know which site plan package I need for my permit?
The site plan you need depends on your project’s scope and your local authority’s requirements. For example, a shed or fence permit may require a Basic Site Plan, while a new build or subdivision may need an Elite Site Plan. Not sure? Request a custom quote and our team will guide you.
