  "articleBody": "When you're thinking about tiny living, you've probably heard the terms \"ADU\" and \"tiny house\" used interchangeably. But for placement planning, understanding the core difference isn't just helpful — it's absolutely crucial! At Zen Tiny Homes, we've helped hundreds of people in San Diego navigate this, and it really comes down to legal classification and foundation.\n\n**Key Difference 1: Legal Classification.** An Accessory Dwelling Unit (ADU) is a legal, land-use classification. It's a secondary housing unit on a property that already has a primary home, defined by zoning. Think of it as a specific type of structure recognized by local government. A \"tiny house,\" on the other hand, is mostly a marketing or descriptive term for any small home. It describes the size and often the aesthetic, not necessarily its legal status.\n\n**Key Difference 2: Foundation.** This is where the rubber meets the road for placement. An ADU is always a permanent real estate asset, built on a foundation, legally tied to your property. It's designed to build equity, much like your main home. A mobile tiny house, often called a THOW (Tiny House On Wheels), is usually considered personal property, like an RV. While it offers flexibility in lifestyle, it typically depreciates in value and has different placement rules.\n\n**When to Choose Each for Placement:** If your goal is a permanent structure that adds value to your property, provides a long-term rental income, or serves as multi-generational housing on an existing lot in areas like Carlsbad or Chula Vista, an ADU (which can *be* a tiny house in size) is likely what you need. Zen Tiny Homes has extensive experience with the engineering and code requirements for foundation-based tiny homes.\n\nIf you're seeking a more flexible lifestyle, perhaps wanting to move your home periodically, and you understand the personal property implications, a THOW might be your preference. However, even THOWs have specific parking and usage regulations that vary wildly by location within San Diego County and beyond. Our team is well-versed in helping clients understand these nuances.\n\n**Cost and Timeline Implications:** Generally, an ADU might involve more upfront costs due to foundation work, permits, and connecting to utilities, but it's a long-term real estate investment. THOWs can sometimes have a lower initial build cost, but their legal placement for permanent residence can be trickier and may not contribute to property value. Our typical build timeline for pre-designed homes is 90 days, but foundation work for ADUs will influence the overall project timeline.\n\n**The Zen Tiny Homes Advantage:** We've spent years working with city and county officials to expand accessibility for tiny home living. This deep local knowledge helps us guide you past the foundational misconception and towards a realistic plan, ensuring your placement choice aligns with your goals and local regulations in areas like Encinitas, Poway, or La Mesa.",
