Are you a homeowner in Atherton curious about the potential of building an Accessory Dwelling Unit (ADU) on your property? With housing shortages becoming a growing concern, many homeowners are turning to ADUs as a practical solution. This guide will walk you through everything you need to know about building an ADU in Atherton, from understanding local regulations to exploring the benefits and steps involved.

What is an ADU and Why They're Becoming Popular

Accessory Dwelling Units, or ADUs, are secondary housing units built on the same property as a primary residence. These units can be detached, attached, or even converted from existing structures like garages. The popularity of ADUs has skyrocketed in recent years, fueled by their potential to address housing shortages, provide additional income, and offer flexible living arrangements.

ADUs are especially appealing in high-demand areas like Atherton, where the housing market is tight. They offer a practical way to increase living space without the need for extensive new construction, making them an attractive option for both homeowners and tenants.

Understanding Atherton's ADU Regulations

Atherton has been proactive in updating its ADU regulations to make it easier for homeowners to build these units. Here's a quick overview of the key policies:

  • Allowed Locations: ADUs are generally permitted on properties where residential uses are allowed. You must have an existing or proposed single-family home or an existing multi-family building.
  • Minimum Lot Size: There's no minimum lot size restriction, so any property size is eligible for an ADU.
  • Number of ADUs Allowed: For single-family homes, you can typically have one or two ADUs. The number of ADUs on multi-family properties depends on various factors.
  • Maximum Square Footage: The size limit of your ADU varies based on whether it's detached or attached.
  • Maximum Height: ADUs can generally be one-story and up to 16 feet in height.
  • Minimum Setbacks: Detached and attached ADUs must be at least 4 feet from the side and rear property lines.
  • Parking Requirements: Conversion and junior ADUs usually don't require parking spaces, whereas attached and detached ADUs might need one parking space.
