However, with the larger size and complexity of this type of build, it’s essential to consider several key factors to ensure the final result aligns with your needs, preferences, and long-term goals.

The choice between a single-story and two-story ADU depends on your property’s size, zoning regulations, and intended use:

• Two-Story ADU: If your lot size is limited or you want to preserve yard space, a two-story ADU is an excellent option. This design allows you to maximize square footage vertically, often providing better privacy and separation between bedrooms and living areas. Keep in mind that some cities in California have height restrictions, such as limiting ADUs to the height of the main residence or a maximum of 16 feet. Ensure your plans comply with local ordinances.
• One-Story ADU: For homeowners prioritizing accessibility, a single-story ADU might be the better choice. This option eliminates the need for stairs, making it ideal for aging-in-place designs or properties where steps could pose a challenge.

A 4-bedroom ADU typically includes 2 bathrooms to balance functionality and space limitations.

• For fewer bedrooms used as sleeping quarters, 1 full bathroom may suffice.
• In two-story ADUs, a half bath on the first floor and a full bathroom on the second is a popular option.

Consider how the four bedrooms will function:

• A master bedroom and guest room are common choices.
• Remaining rooms can be used as an office, yoga studio, home gym, or hobby space.
• Defining each room’s purpose will help determine the floor plan and space allocation.

Storage needs depend on how each room will be used:

• Bedrooms intended for regular use should include spacious closets.
• Rooms used as offices or hobby spaces can have smaller or no closets to maximize room size.

A 4-bedroom ADU is essentially a second home on your property.
