  "articleBody": "Building a detached ADU is a smart move for many Southern California homeowners, offering flexibility and value. However, the planning phase is where most projects either soar or stumble. There are several common pitfalls that, if ignored, can lead to costly delays, redesigns, or even rejection of your plans. Avoiding these mistakes upfront can make your ADU journey much smoother.\n\n- [ ] **Assuming an ADU is exempt from permitting** — While ADU regulations have streamlined the process, a building permit is almost always required for new construction. Failing to secure the necessary permits before starting can result in hefty fines and forced demolition or reconstruction. Always check with your local planning department in areas like Anaheim or Huntington Beach.\n- [ ] **Failing to verify setbacks or easements** — Property lines and easements dictate where you can legally build. Building too close to a property line or over an easement is a common and expensive mistake. Obtain an accurate survey early in the process.\n- [ ] **Overlooking utility capacity and connection costs** — Connecting utilities isn't just about running a line. You need to confirm if your existing municipal water, sewer, or electrical service can handle the extra demand, and factor in potential costs for upgrades, new meters, or even driveway work if trenches are needed.\n- [ ] **Placing underground utilities or equipment too close to property lines** — Even if your ADU structure is compliant, placing utility lines too close to boundaries can cause issues with access for maintenance or future development. Plan these layouts carefully with your contractor and utility providers.\n- [ ] **Submitting incomplete site, structural, or energy documents** — Incomplete applications lead to frustrating plan-review comments and significant delays. Ensure your plans include all required details: site plan, floor plans, elevations, structural calculations, and energy information.\n- [ ] **Treating a prefabricated unit as exempt from site, foundation, utility, or inspection requirements** — Even if you opt for a pre-fab ADU, it still needs a proper foundation, utility connections, and must pass all local inspections just like a stick-built unit. Don't let the 'prefabricated' label mislead you.\n\nHow to use this checklist:\nGo through each item as you plan your detached ADU project. Verifying these points early will help you create a realistic timeline and budget, and prevent surprises down the road. Addressing these potential issues before construction begins is key to a successful project.\n\nAffordable Home Remodeling helps clients avoid these common mistakes with our expertise in detached ADU construction.
