  "articleBody": "Embarking on an Accessory Dwelling Unit (ADU) project is exciting, but successful site planning is crucial to avoid costly mistakes. This isn't just about where to place the building; it's about making sure your ADU fits seamlessly and legally onto your property. Overlooking key details during site planning can lead to delays, budget overruns, or even redesigns down the line. A thoughtful approach now can save you a lot of headaches later. Use this checklist to help identify potential pitfalls before they become real problems, ensuring your ADU project starts on solid ground.\n\n### Your ADU Site Planning Checklist\n- [ ] **Accurate Property Survey** — Don't rely on old maps or approximate property lines; a current boundary/topographic survey is essential for precise planning.\n- [ ] **Easement Identification** — Verify all easements on your property, as these can restrict building locations, utility runs, and access, impacting your ADU's placement.\n- [ ] **Utility Corridor Review** — Confirm the location and capacity of all existing utility lines (water, sewer, electrical, gas); inadequate service can lead to expensive upgrades.\n- [ ] **Grading and Drainage Analysis** — Understand how the ADU will affect site drainage and whether significant grading is required; proper water management prevents future issues.\n- [ ] **Finished Grades and Building Height Verification** — Ensure your planned ADU height complies with zoning by factoring in finished grades, not just foundation height.\n- [ ] **Fire Access Requirements** — Check local fire codes for access routes, defensible space, and potential construction requirements, especially in high-fire zones.\n- [ ] **Coastal/Hazard Zone Review** — If applicable, understand specific requirements for coastal areas, flood zones, or other environmental constraints that might affect your design.\n- [ ] **Standard Plan Suitability** — Don't assume a generic ADU plan will fit your unique site without adjustments; site-specific modifications are almost always necessary.\n\n### How to Use This Checklist\nGo through each item on this checklist before finalizing your ADU site plan. Each point represents a common pitfall that can derail an ADU project if not addressed early. By systematically checking these off, you'll identify potential issues and ensure your site plan is robust and compliant. If any item raises a red flag or you're unsure how to proceed, that's your cue to seek professional guidance. A qualified architect, civil engineer, or experienced contractor can help you navigate these complexities and ensure your ADU is planned correctly.\n\nReady to refine your ADU site plan?
