Accessory Dwelling Units


As part of the City of Menifee’s efforts to plan for housing needs of the community, the City is working on ways to accommodate a variety of housing in Menifee.  One way is by offering Permit Ready Accessory Dwelling Unit (ADU) plans to residents making it easier to build ADUs in Menifee. 

What is an ADU?

Accessory Dwelling Units (ADUs), also known as a "second unit," "in-law unit" or "granny flat" is an attached or detached residential accessory structure on a residential lot that provides independent living facilities for one or more persons. 

Benefits of adding ADUs to your property:

  • Creates more affordable housing 
  • Provides housing for relatives or friends
  • Allows seniors to age in place
  • Increases property value
  • Creates opportunity to earn extra income as a rental unit

Permit Ready ADU Plans and ADU Guidance Handbook

The City of Menifee is working with Design Path Studio to design the ADU plans, along with an ADU Guidance Handbook that will be a user friendly guide that will show how to successfully obtain permits to build an ADU. The plans will be complete sets of code-compliant construction plans and will range in a variety of floorplans and architectural styles.

Progress Update on the Permit-Ready ADU Construction Plans (March 2, 2022)

The Permit Ready ADU construction plans are nearing completion by the City's architect hired to prepare the ADU plans.  Once completed, the architect will submit the plans to the City for plan check review for compliance with applicable building codes.  The City will review the plans and provide comments to the architect identifying any revisions needed to be in fully code compliant. Upon completing required revisions, the architect will submit revised plans to the City for a final plan check and approval.  Once the plans are approved by the City, the plans will be ready and available for public use.  The City anticipates the plans to be available by the end the Spring of 2022. 

ADU Plans are an SB 2 Funded Effort

In March of 2019, the State of California released a Notice of Funding Availability for the Senate Bill 2 (SB2) Planning Grants Program. SB2 was part of a 15-bill housing package aimed at addressing the State's housing shortage and high housing costs. Specifically, it establishes a permanent source of funding intended to increase the affordable housing stock in California. In June of 2020, the City was a awarded with SB2 funds to streamline housing production. One of the selected projects was to prepare permit ready accessory dwelling unit (ADU) plans and an ADU Guidance Handbook. The plans are intended to incentivize, streamline, and minimize costs to homeowners wishing to build an ADU.
