California Mandatory Seller Retrofits: What LA Sellers Must Do Before Close of Escrow
What are California sellers required to do before close of escrow?
California law requires all sellers to install working smoke detectors, carbon monoxide detectors, a water heater seismic bracing strap, and to disclose (and often replace) non-compliant water-conserving plumbing fixtures before escrow closes. In the City of Los Angeles, sellers face additional obligations: obtaining a Residential Property Report (RPR/Form 9) from LADBS, installing a Seismic Gas Shut-Off Valve (SGSOV), certifying water conservation device compliance with LADWP, and confirming impact glazing or approved safety film on sliding glass doors. These are statutory requirements — not requests — and they apply whether you're selling as-is or doing a full renovation first.
California Mandatory Seller Retrofits: What LA Sellers Must Do Before Close of Escrow
One of the most common surprises I see sellers face happens about two weeks into escrow, when they get a list from the escrow company of mandatory retrofit items they need to complete before closing. Not optional. Not negotiable as part of the inspection. Required by law.
It's not a huge financial hit in most cases — though it can be, depending on what's already in place. But it's a stressor sellers didn't see coming, and in a transaction where timing is everything, discovering you need to schedule a plumber, an HVAC tech, and a city report all before close of escrow isn't something you want to figure out mid-deal.
Here's what California law actually requires of sellers, what's specific to the City of Los Angeles, and what you should take care of before you list — not after you're already in contract.
The As-Is Misconception
First, the big one: selling your home as-is in California does not exempt you from mandatory retrofits.
An as-is sale means you won't be making repairs that come up during the buyer's inspection period — foundation cracks, deferred maintenance, the roof that's at the end of its life. That's all negotiable and subject to the buyer's inspection contingency.
Statutory retrofits are different. They're conditions of sale set by California state law and, in Los Angeles, by the municipal code. The escrow company's closing checklist includes them as line items that must be checked off before escrow can close. Selling as-is doesn't move them into the "as-is" category. They remain your obligation as the seller.
I walk every client through this before we even sign the listing agreement. It saves a lot of scrambling later.
What California Requires Statewide
These items apply to every residential property sale in California, regardless of county or city.
Smoke Detectors
California Health & Safety Code Section 13113.8 requires that every single-family home sold have working smoke detectors in every bedroom, outside each sleeping area, and on every floor. For most single-family homes, battery-operated detectors are sufficient. Buildings with three or more units require hard-wired detectors with battery backup.
The seller must provide a written statement to the buyer confirming compliance. In Los Angeles County, this is typically documented on the Smoke Detector and Carbon Monoxide Alarm Compliance form signed at or before close of escrow.
Cost: $25–$60 per detector. A typical three-bedroom SFR in West Hills or Woodland Hills might need 4–6 units if they haven't been updated recently.
Carbon Monoxide Detectors
California Health & Safety Code Section 17926 (the Carbon Monoxide Poisoning Prevention Act, SB 183) requires CO detectors in any home with a gas appliance, attached garage, or fireplace. Every level of the home needs one, and it must be within 10 feet of each bedroom door.
Sellers must provide the same written compliance statement as for smoke detectors.
Cost: $25–$60 per unit. Combination smoke/CO detectors ($45–$90) can satisfy both requirements in one device, which many sellers opt for when replacing aging units.
Water Heater Seismic Bracing
California Health & Safety Code Section 19212 requires that all residential water heaters be braced, anchored, or strapped to resist earthquake motion. This applies statewide. If your water heater doesn't have a double-strap system securing it to the wall, it needs one before you can close.
This one is frequently missed on older homes. A water heater that was installed in the 1990s might have a single strap or no strapping at all. An inspector or licensed plumber can handle this in under an hour.
Cost: $150–$400 installed, depending on access and whether the straps need custom hardware for your tank location.
Water-Conserving Plumbing Fixtures (Disclosure + Possible Replacement)
Under California Civil Code Section 1101.4, all single-family homes were required to have water-conserving plumbing fixtures installed by January 1, 2019. The standards are: toilets must use no more than 1.28 gallons per flush, shower heads no more than 2.5 gallons per minute, and interior faucets no more than 2.2 gallons per minute.
Sellers must complete a C.A.R. Water-Conserving Plumbing Fixture Disclosure (Form WCPF) and deliver it to the buyer. If the property isn't compliant, you must disclose that in writing. Technically, the law doesn't force you to upgrade the fixtures yourself before closing — it transfers the obligation to the buyer — but buyers and their agents increasingly push for compliance as a condition of closing. Many lenders on FHA and VA loans won't fund without it either.
Practically speaking: if your toilets are pre-1994 (3.5 gpf or higher) or your shower heads haven't been replaced in 20+ years, budget for this. Non-compliant toilet replacement runs $50–$400 per toilet plus installation. Shower heads can often be swapped out for $30–$80 each.
If you're selling a home in the City of Los Angeles, this dovetails with the LADWP water conservation certificate requirement below.
Additional Requirements: City of Los Angeles
If your property is within the City of Los Angeles — which includes much of Woodland Hills, Tarzana, Encino, Sherman Oaks, and parts of West Hills — there are additional mandatory items beyond the statewide requirements. Calabasas and unincorporated county pockets have fewer obligations; the full list below is specific to City of LA parcels.
To confirm whether your address falls inside city limits, you can check the LADBS website or ask your agent to pull it up on the city's parcel viewer. It's a quick look-up and it matters.
Residential Property Report (RPR / Form 9)
Under LAMC Section 96.300, the seller of any residential property within the City of Los Angeles must obtain a Residential Property Report from the Los Angeles Department of Building and Safety (LADBS) and deliver it to the buyer before close of escrow — actually, before the buyer signs the purchase agreement, under the strict reading of the code.
The RPR (sometimes called Form 9) discloses any open building permits, code violations, zoning designations, or conditions noted on the property's record with the city. It doesn't catch everything, but it flags what LADBS has on file. If there's an open permit from a 2012 kitchen remodel that was never finalized, it will show up here.
The RPR must be ordered directly from LADBS. Processing takes 3–10 business days in typical conditions, though it can stretch longer during high-volume periods. Order it early — this is one you want in hand before you list, not scrambling to get during the inspection contingency period.
Cost: Approximately $70–$95 for the LADBS fee. If the report reveals open permits or violations, resolving those is a separate cost and timeline conversation.

Seismic Gas Shut-Off Valve (SGSOV)
Under LAMC Section 94.1217, properties with natural gas service in the City of Los Angeles must have an approved Seismic Gas Shut-Off Valve installed on the gas meter before close of escrow. The valve automatically shuts off gas flow when it detects earthquake motion above a threshold (typically 5.4 magnitude), which reduces post-quake fire and explosion risk.
This is a City of LA requirement — not a countywide or statewide rule. If your property is in Calabasas, West Hills near the county line, or unincorporated Ventura County, this doesn't apply to you the same way.
The SGSOV must be an approved model and installed by a licensed contractor. The Southern California Gas Company website maintains a list of approved devices. Most installations are a half-day job.
Cost: $150–$300 for the valve, plus $100–$250 for installation — roughly $250–$550 all in. SoCal Gas sometimes offers rebates; check their website or ask your contractor.
Properties without any gas service are exempt.
Water Conservation Certificate (LADWP)
Under LAMC Section 122.03, sellers within the City of Los Angeles must certify that the property meets LADWP's water conservation requirements — or commit to installing compliant devices — before escrow closes. A Certificate of Compliance must be filed with LADWP.
This is essentially the city's enforcement mechanism for the statewide low-flow fixture requirement, layered on top of the C.A.R. Form WCPF disclosure. In practice, it means an extra step: completing the LADWP form and confirming all toilets, faucets, and shower heads meet the required flow rates. Your plumber or contractor can document this as part of any fixture replacement work.
Impact Glazing or Approved Film on Sliding Glass Doors
Under LAMC Sections 91.6101 and 96.302, sliding glass doors in City of LA properties must have either impact-resistant glazing or approved safety film applied to prevent shattering and injury. The seller must confirm compliance or certify installation before close.
Most sliding glass doors installed or replaced after 1977 already use tempered safety glass, which typically satisfies this requirement. If your home has original 1960s or early 1970s sliding glass doors, this is worth checking.
Cost: If the doors already have tempered glass, the cost is zero — just documentation. If they need safety film applied, budget $3–$8 per square foot installed. Full door replacement is a larger project and is typically only necessary if the doors are failing anyway.
What's Not Required (But Often Confused)
A few items that come up in escrow are sometimes mistaken for mandatory retrofits but are actually negotiable:
- Termite clearance: Not mandated by California law, though VA loans require it. In SoCal, the custom is that the seller typically pays for a Section 1 clearance, but it's a convention — not a legal mandate.
- Roof certification: Not required by California law. Buyers can request it; sellers don't have to provide it.
- Foundation repairs: Required only if a licensed contractor's report identifies structural safety issues, and only to the extent agreed upon in the C.A.R. RPA.
- HVAC servicing: Not mandatory, but frequently requested.

The Timing Argument: Do This Before You List
Sellers who wait until they're in escrow to handle mandatory retrofits end up under timeline pressure. Your buyer's contingency period is typically 17 days for inspections. If you're scrambling to order an RPR from LADBS, schedule an SGSOV installation, and get a plumber out to strap the water heater — all while the buyer's clock is running — you're adding stress and potential delay to the deal.
The smarter move is handling all of this before you list. It typically takes 1–3 weeks to get everything checked off, and completing it in advance gives you a clean, verified retrofit compliance sheet you can share with buyers as part of your disclosure package. It signals that you've done things right.
It also eliminates one of the most common last-minute deal complications I see: a buyer's agent who flags missing retrofit compliance in week two of escrow and uses it as leverage for a price reduction. When your home is already fully compliant, that conversation never happens.
When I prep a listing in West Hills, Woodland Hills, or anywhere else in the West SFV, going through the mandatory retrofit checklist is one of the first conversations we have. If there's an older water heater, 1980s sliding glass doors, or a property that hasn't had an RPR pulled in years, we take care of it before the sign goes up.
If you want to know exactly what the full pre-sale process looks like — from retrofit compliance to pricing strategy — that's exactly the kind of walkthrough I do with sellers before we go to market. Reach out anytime.
Frequently Asked Questions
Does selling a California home as-is mean the seller doesn't have to do the mandatory retrofits?
No. An as-is sale in California means the seller won't make repairs negotiated after inspections — it does not exempt the seller from statutory retrofit requirements. Smoke detectors, carbon monoxide detectors, water heater seismic bracing, and the low-flow fixture disclosure must still be completed before close of escrow regardless of the as-is designation. See Fix Up or Sell As-Is in Woodland Hills? for more on what as-is does and doesn't cover.
What is the RPR (Residential Property Report) and who needs one in Los Angeles?
The RPR, also called Form 9, is a report issued by the Los Angeles Department of Building and Safety (LADBS) under LAMC Section 96.300. It's required for all residential property sales within the City of Los Angeles — not unincorporated county areas. The seller must order it and deliver it to the buyer before escrow closes. It discloses any open permits, code violations, or zoning issues on record with the city. Processing typically takes 3–10 business days from LADBS.
Does every Los Angeles home need a Seismic Gas Shut-Off Valve (SGSOV) when selling?
In the City of Los Angeles, yes — if the property has natural gas service, the seller must install an approved SGSOV under LAMC Section 94.1217 before escrow can close. The valve automatically shuts off gas flow during a seismic event above 5.4 magnitude. The device and installation together run $250–$550. Properties without gas lines are exempt. This requirement does not apply to unincorporated LA County or cities like Calabasas.
Are water-conserving fixtures actually required, or just disclosed?
It's both. California Civil Code Section 1101.4 required that all single-family homes have low-flow toilets (1.28 gpf or less), shower heads (2.5 gpm or less), and faucets (2.2 gpm or less) installed by January 1, 2019. Sellers must disclose compliance status in writing using C.A.R. Form WCPF. If the property isn't compliant, the obligation to upgrade technically transfers to the buyer — but many buyers and their lenders push for pre-close compliance, especially on FHA and VA transactions.
How much do all the mandatory seller retrofits typically cost in Los Angeles?
For a typical single-family home in the City of Los Angeles, budget $700–$2,500 total depending on what's already installed. Smoke detectors run $25–$60 each, CO detectors $25–$60 each, water heater strapping $150–$400 installed, SGSOV $250–$550 installed, water-conserving fixture upgrades $50–$400 per fixture as needed, and the RPR fee from LADBS runs $70–$95. Older homes in Tarzana, Encino, or Sherman Oaks that haven't been updated since the early 1990s tend to hit the higher end of that range.
