What is a Single Family Dwelling?

A single family dwelling (also referred to as a one family dwelling) is a residential structure designed to house one family unit. Unlike multi-family homes (such as duplexes or townhouses), a single family dwelling definition highlights that it is a standalone property with no shared walls, utilities, or land with other households.

Key Characteristics of a Single Family Dwelling

• Detached Structure: Stands alone on its own lot
• Private Entrance & Utilities: No shared systems with neighbors
• Exclusive Outdoor Space: Often includes a yard, garden, or driveway
• Zoning Compliance: Typically follows residential zoning laws for one family dwelling properties

Single family dwellings remain popular due to their privacy, space, and customization potential. However, with California’s rising housing demand, many homeowners are now exploring accessory dwelling units (ADUs) as a smart way to expand their property’s functionality and value.

What is an Accessory Dwelling Unit (ADU)?

An accessory dwelling unit (ADU) is a secondary living space on the same property as a single family dwelling. ADUs can be:

• Detached (a separate backyard cottage)
• Attached (connected to the main house)
• Converted (from garages, basements, or attics)
• Junior ADU (JADU) – A smaller unit within the primary home (max 500 sq ft)

Why Are ADUs Gaining Popularity in California?

• Housing shortages: ADUs provide affordable living spaces.
• Rental income potential: Homeowners earn passive income.
• Multi-generational living: Ideal for aging parents or adult children.
• Increased property value: ADUs boost resale value significantly.

Top Benefits of ADUs

Adding an ADU to your property offers numerous advantages:

Increased Property Value

One of the most common questions homeowners ask is, "How much value does an ADU add?" Research indicates that a well-designed ADU can increase property value by 20-30%, depending on location, size, and quality.

Extra Rental Income

ADUs provide a steady revenue stream, whether through long-term rentals or short-term stays (Airbnb). In high-demand areas like Los Angeles or San Francisco, ADUs can generate $1,500–$3,500/month in rental income.

Flexible Living Arrangements

• Guest house for visitors
• Home office or studio for remote work
• Multi-generational housing for family members

Affordable Housing Solution

ADUs help combat California’s housing crisis by adding livable space without major land development.

Faster Approval Than New Construction

Recent California laws (AB-68, SB-13) have simplified ADU permits, making the process quicker than building a new single family dwelling.

How Much Value Does an ADU Add to Your Home?

The exact value an ADU adds depends on several factors:

Example: A 500 sq ft ADU in Los Angeles could add $150,000–$250,000 to your home’s value while generating $2,000+/month in rent.
