California's Expanded Habitability Standards: What San Diego Landlords Should Inspect Before Listing Rentals (2026)

California's definition of what makes a rental unit legally habitable got more specific on January 1, 2026. Assembly Bill 628, signed by Governor Newsom in October 2025, amended Civil Code §1941.1 to add working stoves and refrigerators to the list of habitability requirements. Rental units covered by new, renewed, or amended leases after January 1, 2026 must include both appliances in good working order, maintained by the landlord, for the duration of the tenancy.

That sounds like a narrow change (just two appliances), but it signals something broader. California is tightening the habitability framework, and the enforcement consequences for landlords who list units with unresolved defects are getting sharper. A tenant in a unit that doesn't meet habitability standards has legal grounds for repair-and-deduct actions, rent withholding, and civil claims. And under AB 628 specifically, a recalled appliance that isn't repaired or replaced within 30 days puts the landlord in violation.

For San Diego landlords preparing to list rental properties this fall, a pre-rental inspection isn't a suggestion anymore. It's the cheapest way to document that your unit meets the current habitability standard before a tenant moves in and finds out it doesn't.

What AB 628 Actually Requires

AB 628 amends the habitability statute to require landlords to provide and maintain a working stove (capable of safely generating heat for cooking) and a working refrigerator (capable of safely storing food) in every rental unit subject to a new, renewed, or amended lease after January 1, 2026.

The law adds these appliances to the same legal category as heat, plumbing, hot water, and weatherproofing. That means a unit without a working stove or refrigerator is legally uninhabitable under the same framework that applies to a unit without running water.

Key details verified from the bill text and legal analyses:

The landlord must maintain both appliances in good working order throughout the tenancy. If either appliance is subject to a manufacturer recall, the landlord must repair or replace it within 30 days of receiving notice. There's a narrow exception for refrigerators: if the tenant and landlord agree in writing at the time of lease signing, the tenant may provide their own refrigerator. But the landlord cannot condition the tenancy on the tenant providing their own appliance. And the stove cannot be waived under any circumstances.

What this means practically: Before listing a rental unit in San Diego, confirm that both the stove and refrigerator are present, functional, in safe condition, and not subject to any active recalls. If either appliance is aging, unreliable, or producing error codes, replace it before the lease is signed. A $500 appliance replacement now prevents a $5,000 habitability claim later.

The Broader Habitability Standard Landlords Must Meet

AB 628 is one update within a habitability framework that already covers a substantial list of building conditions. Under Civil Code §1941.1 (as amended), a habitable rental unit in California must have effective waterproofing and weather protection of the roof and exterior walls (including unbroken windows and doors), plumbing maintained in good working order, a water supply approved under applicable law and capable of producing hot and cold running water, heating facilities maintained in good working order, electrical lighting with wiring and equipment maintained in good working order, adequate garbage receptacles, floors, stairways, and railings maintained in good working order, and (as of 2026) a working stove and refrigerator.

A unit that fails on any of these items is legally uninhabitable, and the tenant has remedies. That's been the law for years. What's changed is that enforcement is getting more aggressive, tenant awareness of rights is higher, and the financial consequences for landlords who list deficient units are escalating.

What a Pre-Rental Inspection Evaluates

A pre-rental property inspection checks the same systems that define habitability, giving the landlord documented evidence that the unit meets the standard before a tenant takes occupancy.

Appliances. The inspector tests the stove for proper operation (all burners, the oven, temperature consistency) and the refrigerator for cooling function, temperature accuracy, and any signs of refrigerant leaks, compressor failure, or electrical problems. The dishwasher, disposal, and range hood (if present) are also tested.

Plumbing. Every faucet, toilet, and drain is tested for function. Water pressure is checked. Supply line condition is evaluated where visible. The water heater's age, temperature output, and safety devices (T&P valve, expansion tank) are assessed. Any signs of active leaks, past water damage, or moisture conditions are documented.

Electrical. The electrical panel is evaluated for capacity and condition. Outlets are tested for function, polarity, and grounding. GFCI protection in bathrooms, kitchens, laundry areas, and exterior locations is verified. Smoke detectors and carbon monoxide detectors are tested (both are required by California law in rental units).

HVAC and ventilation. The heating system is tested for operation. Bathroom exhaust fans are checked for proper function and exterior venting. Kitchen range hood operation is verified. Any HVAC equipment is evaluated for age and condition.

Doors, windows, and weatherproofing. Every window and door is checked for operation, locking hardware, weatherstripping condition, and glass integrity. Any broken windows, failed seals, or non-functional locks are documented.

Moisture and mold conditions. The inspector checks for signs of moisture intrusion, water staining, and conditions conducive to mold growth. Under California law, landlords must disclose known mold contamination, and a pre-rental inspection identifies moisture conditions before a tenant moves in and develops health concerns.

Our mold inspection service provides laboratory testing when moisture conditions suggest mold may be present.

Structural safety. Floors, stairs, and railings are checked for stability and condition. Any trip hazards, loose railings, or structural deficiencies are documented.

System	What's Checked	AB 628 / Habitability Connection
Stove	All burners, oven, temperature consistency	New AB 628 requirement (2026)
Refrigerator	Cooling function, temp accuracy, condition	New AB 628 requirement (2026)
Plumbing	Function, pressure, leaks, water heater	Civil Code §1941.1 habitability
Electrical	Panel, outlets, GFCI, smoke/CO detectors	Civil Code §1941.1 habitability
HVAC	Heating function, ventilation, exhaust fans	Civil Code §1941.1 habitability
Windows/doors	Operation, locks, weatherstripping, glass	Civil Code §1941.1 habitability
Floors/stairs/railings	Stability, condition, trip hazards	Civil Code §1941.1 habitability

Why Documentation Matters More Than Ever

AB 2801 (effective April 1, 2025) requires California landlords to photograph the unit's condition before a tenant moves in. This documentation supports security deposit accounting and protects both the landlord and the tenant by establishing a condition baseline.

A pre-rental inspection report takes this further. It doesn't just photograph surfaces. It evaluates systems, tests function, and documents the working condition of every component that defines habitability. If a tenant later claims the stove was broken when they moved in, or that the water heater wasn't producing hot water, or that the bathroom had a mold condition, the inspection report provides dated, photo-documented evidence of the unit's condition at the time of listing.

That evidence is the landlord's best protection against habitability claims, repair-and-deduct actions, and rent withholding disputes.

The Cost of a Pre-Rental Inspection vs. the Cost of a Habitability Claim

A pre-rental inspection in San Diego costs $300 to $500 depending on the unit size. Compare that to the financial exposure of an uninhabitable unit.

Exposure	Potential Cost
Repair-and-deduct (tenant fixes and deducts from rent)	Cost of repair + lost rent
Rent withholding (tenant withholds until defect is fixed)	Full rent amount until remedied
Habitability lawsuit (tenant sues for damages)	$1,000 to $10,000+ in damages and legal fees
Code enforcement citation	$100 to $1,000 per violation per day
Stove/refrigerator replacement (if caught during tenancy)	$500 to $2,000 plus emergency response cost
Mold remediation (from undiscovered moisture condition)	$1,500 to $10,000+
Lost tenant (vacancy from unresolved habitability issue)	One to three months of lost rent

The inspection costs less than a single month's vacancy in most San Diego rental markets.

San Diego-Specific Considerations

San Diego rental properties have a few local factors that make pre-rental inspections especially important.

Older units with aging plumbing. Properties built before the 1980s may have galvanized steel supply lines or cast iron drains that are approaching end of life. Low water pressure, slow drains, and pinhole leaks are habitability concerns that show up during tenancy if they weren't caught before listing. Our cast iron plumbing guide covers how these systems deteriorate.

Coastal moisture and stucco. Rental properties near the coast are exposed to marine layer moisture that can penetrate stucco cracks and cause concealed framing damage. A pre-rental inspection with moisture measurement identifies these conditions before a tenant moves in and discovers them. Our stucco problems guide covers the most common patterns.

Ventilation in older condos and apartments. Bathroom exhaust fans that vent into the attic (instead of to the exterior) create moisture and mold conditions that become habitability issues. The inspection checks every exhaust fan's operation and termination point.

Smoke and CO detector compliance. California requires working smoke detectors in every sleeping room and on each level of the dwelling, plus carbon monoxide detectors where required. The inspection verifies all detectors are present, properly located, and functional.

How 360 Supports San Diego Landlords

We inspect rental units for landlords and property managers throughout San Diego County. Our pre-rental inspection evaluates every system that defines habitability under current California law, including the AB 628 appliance requirements, and documents the findings with photos in a clear report.

The report serves as your baseline condition documentation and your evidence of compliance. When a tenant moves in, you have a dated record showing that the stove worked, the refrigerator cooled, the plumbing ran, the electrical was safe, and the unit met the habitability standard on the day it was inspected.

For properties where moisture conditions suggest possible mold, we offer mold testing with laboratory analysis. For a broader view of what our inspections cover, our home inspection guide covers the full scope.

Frequently Asked Questions

Q: What is AB 628 and when did it take effect?

AB 628 amended California Civil Code §1941.1 to require landlords to provide and maintain a working stove and refrigerator in rental units. It applies to leases entered into, renewed, or amended on or after January 1, 2026.

Q: Can a tenant withhold rent if the stove or refrigerator breaks?

Under California habitability law, tenants have legal remedies when the unit doesn't meet habitability standards, including repair-and-deduct and rent withholding. Since AB 628 added stoves and refrigerators to the habitability standard, a broken appliance now triggers these same protections.

Q: How much does a pre-rental inspection cost in San Diego?

Most pre-rental unit inspections cost $300 to $500 depending on the size of the unit. This is significantly less than the cost of a single habitability claim, code enforcement citation, or vacancy caused by an unresolved defect.

Q: Does the landlord have to replace recalled appliances?

Yes. Under AB 628, a landlord must repair or replace a stove or refrigerator that is subject to a manufacturer or public entity recall within 30 days of receiving notice.

Q: Can a tenant provide their own refrigerator instead of the landlord?

Yes, under narrow conditions. The agreement must be in writing, made at the time the lease is signed. The landlord cannot condition the tenancy on the tenant providing the appliance. And the tenant can reverse the election with 30 days written notice. The stove cannot be waived under any circumstances.

Q: What else does California habitability law require besides appliances?

Effective waterproofing, working plumbing with hot and cold water, adequate heating, working electrical systems, maintained floors and stairs, unbroken windows and doors, and adequate garbage receptacles. AB 628 added stoves and refrigerators to this list.

Q: Should I get a pre-rental inspection for a condo I'm renting out?

Yes. The habitability standard applies to all residential rental units regardless of property type. A condo unit inspection checks every system inside your unit that defines habitability.

Q: Does a pre-rental inspection check for mold?

The inspection identifies moisture conditions conducive to mold growth (water stains, elevated moisture readings, ventilation deficiencies). Confirming mold presence requires separate laboratory testing with air and surface sampling.

Q: How often should I inspect my rental property?

There's no state-mandated frequency for ongoing inspections, but inspecting before each new tenancy and periodically during long tenancies (annually or every two years) helps catch maintenance issues before they become habitability violations.

Q: What documentation should I keep from the inspection?

Keep the full inspection report with photos, the inspector's findings, and any follow-up repair documentation. This file, combined with the AB 2801 move-in photos, creates a comprehensive condition record that protects you in any dispute.

The Compliance Question Has Changed

California's habitability standard isn't getting simpler. AB 628 is the latest expansion, and it won't be the last. Each update narrows the gap between what a landlord can ignore and what a tenant can enforce.

A pre-rental inspection closes that gap before it becomes a dispute. The unit either meets the standard or it doesn't. The inspection tells you which, documents the evidence, and gives you the opportunity to fix what needs fixing before someone else finds it for you.
