In California, an ADU must be at least 150 sq ft, with maximum sizes varying by type: detached units can be up to 1,200 sq ft, attached units up to 50% of the primary home's size (max 1,200 sq ft, min. 800 sq ft guaranteed), and conversion ADUs within existing structures typically have no maximum size restriction. Specific allowances depend on local regulations, zoning, and property constraints. Better Place Design & Build will evaluate your property to determine the ideal ADU size based on your local guidelines.

In California, ADU permit fees generally range from approximately $2,000 to $8,000, depending on local jurisdiction, unit size, and project scope. For example, in San Diego County, permits typically cost around $3,900 to $5,000 for units near 800 sq ft, including both plan review and permit issuance fees. Impact fees are waived for ADUs under 750 sq ft statewide, but school district fees usually apply to ADUs larger than 500 sq ft.

In 1,000 sq ft, you can comfortably fit a 3-bedroom, 2-bath layout that includes a central living, dining, and kitchen area. A well-designed 1,000 sq ft ADU typically features one primary bedroom with a private bathroom, two additional bedrooms sharing a second bath, and still provides space for amenities like laundry, storage closets, and an efficient kitchen area. Thoughtful floor planning ensures this layout feels spacious rather than cramped, making it ideal for families, rental properties, or multi-generational living.

A 1,000 sq ft space typically resembles a modest single-family apartment or a spacious two-bedroom condo, often laid out in a rectangle around 25 feet wide by 40 feet long. Within this size, you can comfortably accommodate three bedrooms, two bathrooms, and a combined living, dining, and kitchen area. Rooms in this footprint are efficiently designed but feel spacious and practical, allowing room for amenities like a laundry area, closets, and even a kitchen island. Visualizing it, think of a compact yet fully functional home, perfect for families or renters who value efficient, smartly organized spaces.

When choosing an ADU floor plan, prioritize space efficiency, privacy, storage, and versatility. Consider an open-concept design combining living, dining, and kitchen areas for enhanced functionality. Ensure bedrooms offer privacy, especially the primary suite. Include sufficient storage like closets and a pantry, dedicated laundry space, and flexible rooms that adapt over time (guest rooms, home office, rental potential). Also factor in accessibility, local regulations like setbacks and height limits, and how the ADU integrates with your existing property. A well-designed floor plan maximizes comfort, value, and usability.

No, a 1,000 sq ft home isn't considered a tiny home. Typically, "tiny homes" range from 100 to 400 sq ft, emphasizing extreme compactness and minimalism. In contrast, a 1,000 sq ft space offers significantly more room, usually accommodating multiple bedrooms, bathrooms, and ample living space—comparable to a small house or spacious apartment. It's a comfortable, practical size that balances compact living with everyday functionality.
