Monterey County ADU Resource Guide

Ready to start planning your ADU? Here are some local resources that can help.

WATER AVAILABILITY

If you’re located on the peninsula, water availability may be a challenge. The cities of Seaside and Pacific Grove currently do have water credits available for purchase. Several areas of the Peninsula have water availability issues. However, it may still be possible that you have water credits available or existing water credits to accommodate certain planned ADUs. Click here for a form from the Monterey Peninsula Water Management District (MPWMD) which can help to calculate the amount of water that is needed for your ADU or find other useful forms on MPWMD’s website. Learn more about the Pacific Grove Water Purchase wait list. For more information on how to move around water credits in your home, read this guide and look at this list of rules from the MPWMD. Contact the Monterey Peninsula Water Management District for more questions at (831) 658-5601.

WATER SAFETY

If you live in unincorporated North County areas, you may have issues with water quality that could stand in the way of constructing an ADU. To find out more, contact the county at (831) 755-5025.

FINANCING

One of the biggest barriers for most homeowners is financing their ADU. There are currently no ADU specific loan products available in Monterey County. However, conventional financing options may be an option for you to finance your ADU.

PUBLIC PLANS

Monterey County does not have pre-approved plans available at this time. However, to save on cost of design, some publicly available plans from San Diego have been verified by our partners as locally adaptable.

ARCHITECTS

There are several local architects who are knowledgeable about ADU design and can adapt plans or design new plans for you. Please contact Kelly deWolfe, Impact Associate for Affordable Housing at kelly.dewolfe@unitedwaymcca.org for more information. 

PREFABRICATED OPTIONS

United Way of Monterey County, with the help of our partners, has created a list of local building companies creating prefabricated ADUs. Building your ADU prefabricated can save on construction costs.

LOCAL CODE AND STATE LAW

Some restrictions may still apply to your property; however, many local limits have been eliminated as of January 1, 2020. Learn more about the local city code for your area and the 2020 state law information.
