Separate Utilities  ADU (Accessory Dwelling Unit)

Features of ADUs, including separate utilities:

  • Independent Living: ADUs often have separate utilities, including electricity, water, and gas meters, allowing for independent living from the main house.

  • Privacy: Separate utilities enable tenants or family members living in the ADU to maintain their privacy and autonomy, without relying on the main household for utilities.

  • Cost Efficiency: With separate utility meters, tenants can be billed directly for their usage, promoting accountability and potentially reducing utility costs for both parties.

  • Flexibility: Having separate utilities allows for flexible arrangements, such as renting out the ADU or accommodating extended family members, without affecting the main household’s utility consumption.

  • Legal Compliance: In many jurisdictions, having separate utilities for ADUs may be a requirement to comply with building codes and zoning regulations, ensuring the unit meets legal standards for habitability and safety.

ADU's Allow For More Livable Space

  • Increased Property Value: ADUs can significantly boost the value of your property by adding desirable living space.

  • Rental Income: Renting out the ADU provides a reliable source of additional income, helping offset mortgage costs or supplementing your monthly budget.

  • Multigenerational Living: ADUs offer a convenient living arrangement for extended family members, allowing for privacy and independence while staying close to loved ones.

  • Home Office or Studio: ADUs provide a separate space for working from home, pursuing hobbies, or running a small business without disrupting the main household.

  • Guest Accommodations: Having an ADU offers comfortable lodging for guests, ensuring they have their own space and privacy during visits.

  • Aging in Place: ADUs can be designed to accommodate aging family members, allowing them to stay close while maintaining independence and privacy.
