REO property preservation is the work that keeps a vacant, foreclosed home secure, safe and saleable until it sells: securing doors and windows, winterizing, cleaning out, maintaining the yard and pool, and documenting the condition. In California it’s also a legal duty. The owner of a vacant home bought at or acquired by foreclosure must maintain the exterior, and after notice a local agency can fine up to $2,000 a day, rising to $5,000 a day after 30 days, under Civil Code §2929.3.
This guide covers the tasks, the California rules and how to document the work.
What California requires of a vacant REO owner
Civil Code §2929.3 applies to residential property purchased at a foreclosure sale or acquired through foreclosure, once it’s vacant. It defines failure to maintain as failing to care for the exterior, giving examples:
- Permitting excessive foliage growth that lowers the value of surrounding properties
- Failing to prevent trespassers or squatters from remaining on the property
- Failing to prevent mosquito larvae from growing in standing water, such as an unmaintained pool
The process is notice first: the local agency must give written notice describing the problem, at least 14 business days to start fixing it (with a possible 10-business-day extension) and at least 16 more to finish, unless a condition threatens public health or safety. Fines then start the day after the period ends, and the agency must consider good-faith efforts. Many cities and counties also run their own vacant-property registration or blight programs, so check local rules for each property.
Fire safety: defensible space and weeds
Many North Bay properties sit in mapped fire hazard severity zones. In state responsibility areas, anyone who owns or controls a building must keep defensible space for 100 feet around it under Public Resources Code §4291, and cities and counties enforce their own weed-abatement rules. A vacant home with overgrown grass and brush is a fire risk to neighbors, a likely citation, and a harder sale. Schedule mowing and brush clearing before fire season, and keep the records.
The preservation checklist
| Task | When | Notes |
|---|---|---|
| Occupancy check | Immediately after the foreclosure | Confirm vacancy before any lock change; occupied homes need lawful notices |
| Initial securing | Once confirmed vacant | Rekey, secure windows and doors, board only where needed; post contact signage where local rules require |
| Initial inspection and photos | At securing | Dated photos of every room, the exterior, utilities, damage and personal property |
| Utilities | At securing | Decide on shutoff or service per the owner’s policy; protect against freeze where needed |
| Winterization | Before cold weather, especially at elevation | Drain and pressure-test plumbing; tag fixtures; record the method |
| Debris and personal property | After required notices | Follow California’s rules for property left behind; don’t simply dump belongings |
| Yard, weeds and defensible space | Recurring | Mow, clear brush, remove hazards; fire-season priority |
| Pool and standing water | Recurring | Drain, treat or cover; mosquito control |
| Roof tarps and emergency repairs | As needed | Stop active leaks; document before and after |
| Recurring inspections | On a set schedule | Check for break-ins, leaks, squatters and code notices |
Occupied properties: don’t preserve your way into an eviction
Preservation work starts only after the home is confirmed vacant. Changing locks, removing doors or windows, or shutting off utilities to force someone out is unlawful self-help, and Civil Code §789.3 makes a landlord liable for damages plus up to $100 a day for it. Tenants after a foreclosure are entitled to at least 90 days’ written notice, and fixed-term leases signed before the sale can often run to their end (Code of Civil Procedure §1161b). Former owners who stay must be served a 3-day notice to quit and removed only through the courts. Coordinate occupied properties with counsel; see REO asset management for how occupancy fits the overall timeline.
Documentation that protects the owner
- Dated, labeled photos before and after every visit and every job
- Work orders, invoices and contractor licenses and insurance
- Copies of every notice from a city or county, and the response
- A log of utility status, winterization dates and inspection visits
- An inventory of personal property found, and how it was handled
These records answer most later disputes with code enforcement, buyers, insurers and auditors. They also feed the condition notes in a broker price opinion; see BPOs and REO valuation.
Preservation and the sale price
Well-kept REOs show better and draw more financed buyers, because lenders’ appraisers flag safety hazards, missing systems and active leaks. A neglected vacant home can lose value quickly to water damage, mold, theft and vandalism. When a buyer’s inspection turns up damage that happened after the foreclosure, it becomes a price negotiation. Buyers can read our buyer’s due diligence checklist to see what they’ll look for.
Who handles preservation
Large servicers usually use national preservation vendors, with a local listing broker monitoring the property, reporting problems and recommending work. Smaller lenders and private-money lenders often rely on the listing broker to coordinate local contractors directly. Either way, someone local should see the property regularly.

Questions owners and asset managers ask
Who is responsible for a vacant foreclosed home in California?
The legal owner, usually the lender or whoever bought it at the trustee’s sale, under Civil Code §2929.3.
How much can a city fine for a neglected REO?
Up to $2,000 a day after the notice and cure period, rising to up to $5,000 a day after 30 days.
Can we change the locks right after foreclosure?
Only once the property is confirmed vacant. If anyone lives there, follow the notice and court process.
Do we need to winterize in the North Bay?
At higher elevations and in colder pockets, yes. Freeze damage to plumbing in a vacant home is a common and expensive surprise.
