Water-Conserving Fixtures: What LA Home Sellers Must Know

What are the water-conserving fixture requirements when selling a home in Los Angeles?

California law requires sellers of homes built before 1994 to disclose whether any plumbing fixtures exceed state water-conserving thresholds, using CAR Form WCMD. Sellers of City of Los Angeles properties face a stricter second requirement under LAMC Section 122.03: noncompliant fixtures must be replaced before close of escrow, and a Water Conservation Certificate of Compliance must be filed with LADWP. State law requires disclosure; the City of LA requires installation.

Most sellers in the City of Los Angeles find out about this requirement somewhere between listing and closing. An inspector flags old toilets. The escrow officer asks about the Certificate of Compliance. Suddenly there's a new compliance item at exactly the wrong moment.

This is one of the more consistently misunderstood seller requirements in an LA home sale. Here's what both laws actually require, so you're not learning about it on the fly.

Two Layers: State Law and the LA City Ordinance

The fixture requirement in Los Angeles comes from two separate sources, and they don't mean the same thing.

The statewide layer (California Civil Code §1101.4) covers all residential properties built before January 1, 1994. If your home predates that year, you're required to disclose whether the property has any noncompliant plumbing fixtures. That disclosure happens on a specific California Association of Realtors form: the Water-Conserving Plumbing Fixtures and Carbon Monoxide Detector Advisory (Form WCMD). Under state law alone, this is a disclosure obligation, not an installation mandate.

The City of LA layer (LAMC Section 122.03) goes further. For properties within the City of Los Angeles, noncompliant fixtures must actually be replaced before you enter into a sale agreement, or at the latest, before escrow closes. After installation, you notify the Los Angeles Department of Building and Safety within 10 days. A Water Conservation Certificate of Compliance is then filed with LADWP as part of the escrow package.

The distinction matters. A seller in Pasadena or Santa Monica (both separate incorporated cities with their own municipal codes) has a disclosure obligation under state law. A seller in the City of LA has that disclosure obligation plus an installation requirement.

What Counts as Noncompliant

The thresholds are set by California Civil Code §1101.3:

• Toilet: More than 1.6 gallons per flush
• Showerhead: More than 2.5 gallons per minute
• Interior faucet: More than 2.2 gallons per minute
• Urinal: More than 1.0 gallon per flush

These are manufacturing thresholds, not usage thresholds. If a toilet was built to use 3.5 gallons per flush (common in pre-1990 homes), it's noncompliant even if it's functioning perfectly. Noncompliant fixtures are standard in older Hollywood Hills, Laurel Canyon, Silver Lake, and Los Feliz homes, where buyers pay a premium for original character and the plumbing is often equally original.

Does This Apply to Your Property?

Year built matters. The state law applies to homes built before January 1, 1994. California updated its building codes that year to require water-conserving fixtures in new construction. If your home was built after that date, it's presumed compliant. If a remodel ever replaced fixtures with older stock, that's worth a closer look.

Location within LA County matters. The LAMC 122.03 installation requirement applies only to properties within the City of Los Angeles. Properties in Beverly Hills, Santa Monica, Burbank, Culver City, or unincorporated LA County are subject to the state disclosure law but not this city ordinance. Some Westside and Valley addresses surprise sellers on this point: check whether your address falls inside city limits before your listing appointment.

This is separate from the 9A Report. The Residential Property Report (9A Report) is a different LADBS document covering zoning, code violations, and permit history. Water conservation compliance runs through LADWP and LADBS on a separate track. City of LA sellers need both.

How This Plays Out in Escrow

Your escrow officer for a City of LA transaction will include a water conservation section in the seller's compliance package. You'll complete an Owner's Declaration confirming whether the required devices are installed or will be installed before closing.

If your home already has compliant fixtures, you confirm and move on.

If it doesn't, you have two practical paths:

1. Replace before listing. This is the cleaner approach. A licensed plumber can handle toilets; showerheads and faucet aerators are DIY-friendly. After completion, notify LADBS within 10 days. For a three-bathroom house, the full job typically runs $400 to $1,500 depending on fixture selection and whether you hire out.

2. Replace during escrow before close. Your escrow officer holds compliance until the Certificate is filed with LADWP. This works but adds a task to an already compressed timeline. Discovering the issue after escrow opens is better than not discovering it, but replacing fixtures before listing is almost always less stressful for everyone involved.

What you can't do is decline to install and still close. Under LAMC 122.03, installation is required for City of LA sellers.

The Bigger Picture for Pre-1994 Homes

If your home was built before 1994 and you've never specifically replaced fixtures with water-conserving models, assume you have at least some noncompliant items. The dual-flush toilet installed in 2008 is probably fine. The original 1963 toilets in the guest bathroom almost certainly are not.

Water fixture compliance is inexpensive to address when planned and creates unnecessary friction when left to escrow. A quick audit of your bathrooms and kitchen faucets three to six months before listing lets you deal with it on your schedule.

It's worth noting that a pre-1994 City of LA home often triggers several disclosure requirements at once. Lead-based paint disclosure applies to homes built before 1978. Mold disclosure requirements apply regardless of age. Running through the full compliance picture before listing saves time and reduces escrow surprises.

Frequently Asked Questions

Does the water fixture requirement apply to homes built after 1994?

No. California Civil Code §1101.4 applies to homes built before January 1, 1994. Homes built after that date were required under building codes to have water-conserving fixtures, so they're presumed compliant. If a post-1994 remodel introduced older noncompliant models, that's an edge case worth discussing with your agent before listing.

What if I've already replaced some fixtures but not all of them?

You disclose the status of all fixtures on Form WCMD, noting which are compliant and which are not. Under state law, that disclosure satisfies the statewide requirement. Under the City of LA ordinance, the noncompliant fixtures still need to be replaced before close of escrow. Partial replacement is common and your escrow officer handles it routinely.

Is the Water Conservation Certificate the same as the 9A Report?

No. They're separate documents from different agencies. The 9A Report comes from LADBS and covers zoning, code violations, and open permits. The Water Conservation Certificate is filed with LADWP under LAMC Section 122.03. Both are required for City of LA residential sales and are coordinated through your escrow officer.

How much does it cost to replace noncompliant fixtures?

For a typical three-bathroom house, plan on $400 to $1,500 depending on fixture selection and whether you hire a plumber. Standard water-conserving toilets run $150 to $500 per unit. Low-flow showerheads and faucet aerators are $20 to $80 each and are straightforward to install yourself. Compared to most other compliance costs in an LA home sale, this is one of the more manageable items.

Which agent should I work with when selling a City of LA home?

For a City of LA sale, you want an agent who treats pre-listing compliance as a standard part of the process, not a checklist item discovered in escrow. The 9A Report, water conservation compliance, mold disclosure, lead paint disclosure for pre-1978 homes, and any active permits should all be addressed before you list. I work with sellers regularly across the City of LA, including in the Hollywood Hills, Los Feliz, Silver Lake, and on the Westside, and pre-listing prep is part of every listing engagement.

Water fixture compliance is one of those items experienced LA agents address before it becomes a problem. If you're getting ready to list a City of LA home built before 1994, put this on the pre-listing checklist alongside the 9A Report, lead paint, and mold disclosures. A short audit of your bathrooms and kitchen faucets now saves a lot of back-and-forth during escrow.
