Monterey Peninsula Water Credits: Important Changes Coming in January 2027

For homeowners, buyers, sellers, and investors on the Monterey Peninsula, water is often one of the most important factors affecting a property's value and future remodeling potential. The Monterey Peninsula Water Management District (MPWMD) has adopted changes that property owners should understand, particularly regarding water credits and how long they remain available for future use.

Water credits are a valuable resource that can be created when legal water fixtures are permanently removed, replaced with qualifying high-efficiency fixtures, or when portions of a property's historical water use are permanently abandoned. These credits may be used for future improvements on the same property, subject to MPWMD rules and approval.

As of today, MPWMD Rule 25.5 states that a documented Water Use Credit may be used on the property for up to ten years following the documented permanent abandonment of use. After that period, any unused credit expires. In January 2027, things may be changing. If water credit expiration periods are shortened from 10 years to 5 years for certain credits, property owners with unused credits could face a much narrower window to utilize those credits for future improvements.

This is especially important for:

• Owners considering future remodels or additions

• Vacant land owners planning future construction

• Buyers evaluating a property's expansion potential

• Sellers marketing a property with documented water credits

Water credits can significantly affect a property's development opportunities, making it important to understand exactly what credits exist and when they expire. Because every property is different and water credits can have unique timelines and requirements, property owners should always confirm the status of their credits directly with the District before making plans based on them.

MPWMD has also published changes to certain credit calculations. For example:

• Credits for some High Efficiency Toilets (HETs) expire on January 1, 2027.

• Credits for Ultra High Efficiency Toilets (UHETs) are reduced beginning January 1, 2027.

These changes further highlight the importance of confirming current rules before planning a project.

My Advice: Verify Before You Buy, Sell, or Remodel. Water regulations on the Monterey Peninsula are unique and frequently updated. While articles like this can provide a helpful overview, they should never be considered a substitute for direct confirmation from the Monterey Peninsula Water Management District.

Before making decisions based on water credits, always:

1. Request documentation of any existing water credits.

2. Verify expiration dates directly with MPWMD.

3. Confirm that credits can be used for your intended project.

4. Check for any recent ordinance changes that may affect the property.

Rules, calculations, and eligibility requirements are always subject to change, and each property may have unique circumstances.
