New Plumbing Codes in Riverside for 2026 — What You Need to Know

As we approach 2026, homeowners, contractors, and business owners in Riverside need to prepare for important changes to local plumbing regulations. The city is adopting the latest statewide building standards — and that includes updated plumbing codes that will affect everything from remodels to new construction. At Elite Plumbing & Drains LLC, we believe it’s vital for you to know what’s changing, why, and how it might impact your next project or repair.

What’s Changing: Adoption of the 2025 Code

On January 1, 2026, the city of Riverside, CA will begin enforcing the updated 2025 California Building Standards Code (Title 24), which includes the revised 2025 California Plumbing Code (Part 5). Riverside+2Riverside+2

This update is part of the state’s triennial code cycle and applies to all new permit applications submitted on or after January 1, 2026. Projects already submitted and “deemed complete” before that date may continue under the older 2022 standards — as long as the plan‑check remains active. Riverside+1

In simple terms: if you’re planning any remodels, additions, or new construction requiring a plumbing permit — starting 2026 — you’ll be under the new regulations.

Major Impacts & Changes to Know

While the full 2025 Plumbing Code is long and detailed, here are some of the key changes and trends that homeowners and contractors in Riverside should be aware of (based on statewide code updates and recent amendments proposals).

• Updated Standards for Fixture Efficiency & Water Use

Water conservation remains a big priority across California. The new code reflects this with more stringent requirements for plumbing fixtures — especially in newly built or remodeled residences and accessory units. Expect stricter standards for water‑efficient toilets, showerheads, and faucet fixtures. All Pro Plumbers+2Sacramento Plumbing Solutions+2

This means if you’re doing a bathroom or kitchen remodel (or building an ADU/secondary dwelling), plan for fixtures that meet low‑flow and efficiency requirements.

• Revised Regulations for Recycled Water / Greywater & Water Safety

Under changes proposed to the new plumbing code, there is more emphasis on safe use of recycled water systems — including design standards for plumbing related to greywater reuse (for irrigation, etc.). These changes aim to regulate supply, back‑flow prevention, and distribution systems. Water California+2California Housing Dept.+2

For Riverside homeowners interested in sustainable plumbing options — such as greywater reuse — this is promising news. However, it also means that installations must meet stricter code requirements and may require more careful design and permitting.

• Stricter Material & Installation Requirements (Especially for Older Systems)

The 2025 Plumbing Code updates references, among other things, to the newer 2024 Uniform Plumbing Code (UPC), which means material allowances, installation practices, and compliance standards may shift compared to older codes. California Housing Dept.+1

For older homes in Riverside — especially those with older plumbing material (galvanized steel, outdated piping) — this may affect remodels or repairs. Contractors (like us) will need to ensure upgrades meet new safety and compliance standards.

• Permitting & Plan‑Submittal Process — Getting in Before 2026

Because the code goes into effect January 1, 2026, any permit applications submitted before that date (and deemed complete) can still follow the old 2022 code. Riverside+2Riverside+2

If you’re planning a remodeling or plumbing upgrade project soon, it may be worth submitting permit applications now — to avoid any unexpected cost or compliance increases linked to the new code.

But once 2026 begins, all new applications, late submissions or restarted permits will need to meet the 2025 standards.

What This Means for Riverside Homeowners & Landlords

• If you own an older home and plan bathroom/kitchen remodels — expect stricter requirements for fixtures, materials, and possibly more thorough inspections. 
• For property owners aiming to install greywater or recycled‑water systems — newer regulations could make compliance easier (with clearer rules), but design and installation must meet the updated code. 
• Willful ignorance of the new standards won’t hold up: as of January 1 2026, compliance is mandatory for new permits — non‑compliant work may be rejected, delayed, or require rework. 
• For maintenance, small repairs, or existing systems: Unless you’re making structural changes or significant upgrades, they likely remain unaffected — but if you upgrade or replace major components (water heaters, drainage, piping), then new code standards may apply.
