Vacant Building Violations and Registration Ordinances

Every list I pull starts the same way. I sort by case type, and the vacant building cases go to the top before I read anything else.

A vacant building violation is a code enforcement case opened against an unoccupied building that fails the standards a city applies to empty structures: open to entry, unsecured against weather, surrounded by debris or overgrowth, or not registered where registration is required. It is a maintenance case, not a penalty for the building being empty, and it is public record like any other code violation.

What matters to an investor is what the case implies about the owner. Nobody lives there. Somebody still pays the taxes, plus a monthly inspection fee in cities that run a monitoring program, on an asset producing nothing. That is a specific kind of stuck, and it lands in the record long before anything hits the MLS. This sits inside the wider investor's guide to building code violations.

What counts as a vacant building

There is no national definition. Each city writes its own, so the same house gets treated three ways in three jurisdictions. The common elements are an occupancy clock (30 days, 60, a year), a condition trigger, and a complaint or inspection that opens the file. Most cities do not care that a building is empty. They care that an empty building is open to entry, deteriorating, or drawing complaints.

Seattle codifies its standards in SMC 22.206.200: secured against unauthorized entry, protected from the weather, and clear of debris, overgrowth, junk vehicles, and graffiti. Tacoma is blunter. TMC 2.01.040 defines a derelict building as any structure "not approved for human occupancy," folding condition and vacancy into one status. Both sit on top of RCW 35.80, Washington's unfit-dwellings statute, which lets a city declare a building unfit and bill the owner for repair, securing, or demolition. That is where the teeth come from.

Keep one distinction straight, because cities and list vendors blur it constantly: a vacant property is empty, an abandoned property is empty and neglected. Vacant building violations live on the second one. An empty rental between tenants does not get a case.

What the city does after the flag

Seattle and Tacoma both publish their case type, and they run the escalation almost backwards from each other. The contrast is the useful part.

In the Seattle column the number that matters is the monthly fee: at the top of that range an owner pays over $9,000 a year to keep a building empty, and the city knows exactly who to invoice. In the Tacoma column it is the Certificate of Complaint, because that one attaches to the title and has to clear before a clean sale. Neither city is unusual. Chicago's 13-12-125 requires registration within 30 days of vacancy and treats every unregistered day as a separate offense. Register, secure, maintain, or the city does it and bills you.

Registration ordinances and the records they leave

Registration is the part most investors skip, and it produces the best contact data on the list.

A registration form is not a citation. It is a form the owner fills out and signs. Tacoma gives an owner ten calendar days from the Certificate of Complaint to file one, carrying the street address, the tax parcel number, the name and daytime and evening phone numbers of the owner or a responsible party, and how long they expect the building to stay vacant. The owner then records a notice with the county auditor confirming it.

Think about what that is: a phone number, volunteered by an owner, attached to an empty building, in a public file. The tax roll gives you a mailing address that might be a decade stale. The registry gives you somebody who answered the question this year. That is why finding the owner of a vacant house starts at the registry when one exists. Where a city runs one, the list is usually requestable, and our public records request walkthrough covers the wording.

What 2,170 vacant building cases look like

The honest limitation first. Of our seven Puget Sound markets, only two publish a Vacant Building case type at all: Seattle and Tacoma. The rest use a generic category or leave the field blank, and 49,848 of 88,179 cases carry no type. These counts are a floor, not a census.

Source: FlaggedLeads production database, pulled 2026-09-02. Sample: 88,179 code violations on 48,915 properties across Seattle, Tacoma, Bellevue, Burien, Shoreline, Mountlake Terrace, and unincorporated Pierce County.

Three findings I would not have guessed.

The two cities disagree about what "resolved" means. Tacoma closes 88% of its vacant building cases. Seattle closes 32% and parks the rest in statuses like NOV Issued (153), Emergency Order to Vacate and Close (151), and Under Investigation (126). The oldest Seattle case still sitting in NOV Issued opened on 19 May 2011. Fifteen years. Read each city's status conventions before you filter on them.

These are repeat offenders. The average property across our markets carries 1.80 code violation cases. A property with a vacant building case carries 2.93, and 41% of them carry three or more against 17% of all properties in the file. That is the co-occurrence signal stacking runs on. 371 (23%) have had two or more separate vacant building cases over the years. One has twelve.

Vacancy and emergency orders travel together. 333 of the 1,609 vacant building properties (21%) also carry an Emergency case, against 6.8% of all properties in the file. Roughly three times the rate. An empty building the city has also called an emergency is about as loud as the public record gets.

Why the empty ones get read first

Vacancy is rare, which is what makes it worth sorting on. ATTOM put the national rate at 1.3% of 104.6 million residential properties in Q3 2026, and of the 259,666 properties in foreclosure, only 8,482 were already abandoned. Vacancy plus a code case is a thin slice of a thin slice.

It is also expensive to sit on. The US Fire Administration counted an estimated 23,800 vacant residential building fires a year from 2013 to 2015, about 6% of all residential building fires, and our fire-damaged property leads data runs on that overlap. An empty building catches fire, gets squatted, gets stripped, and costs more to save every winter. The owner already knows it is a liability, which makes for a very different conversation than the one you have with somebody who thinks their house is fine.

How to find vacant building violations

1. Pull the city's code enforcement export and filter case type to vacant, derelict, unfit, unsafe, or dangerous structure. Mechanics: how to look up code violations. Whether your city publishes any of it is in our directory of code enforcement open data by city.
2. Search the vacant building registry separately. Different list, often a different department, usually better contact data.
3. Check status conventions before filtering. As the Seattle and Tacoma split shows, "Closed" means different things in different systems.
4. Stack it. A vacant case plus an emergency order plus an old unresolved date beats a lone vacant case from last month, and our distress signal data shows how often they pile up on one parcel.
5. Attach an owner. Registry first, assessor roll second. Full method: the distressed property playbook.

For a whole market rather than one address, pulling a vacant property list from public records is the list-building version of this page, and which violation types signal a motivated seller ranks vacancy against the other case types.

Frequently asked questions

What counts as a vacant building?

Most cities pair an occupancy test (empty 30, 60, or 90 days) with a condition test (open to entry, unsecured, deteriorating, or drawing complaints). Seattle requires a vacant building to stay secured, weather-tight, and clear of debris and overgrowth. Tacoma skips the clock and defines a derelict building as one not approved for human occupancy. An empty rental between tenants almost never qualifies.

What happens when a building is declared vacant?

The owner gets a notice and a compliance deadline. Miss it and the escalation is similar everywhere: monitoring or registration, recurring fees, daily penalties, then the city securing or demolishing the building at its own expense and billing the owner. In Washington that cost recovery runs through RCW 35.80.030, and an unpaid bill becomes a lien. Full ladder: the code enforcement process.

Do I have to register a vacant property?

If your city has a registration ordinance and your building meets the trigger, yes, and the deadlines are short. Tacoma gives ten calendar days from the Certificate of Complaint; Chicago gives 30 days from the building becoming vacant. Failing to register is itself a violation, and most ordinances treat each day as a separate offense.

How much does a vacant building violation cost the owner?

Two meters run at once. Fines start at $150 per day in Seattle and $250 per occurrence in Tacoma. Program fees are charged whether or not anything is contested: Seattle's monitoring runs $336.82 to $781.84 per month, Tacoma charges $250 to register plus $500 each anniversary. Abatement costs land on top if the city boards the building up.

Can the city demolish a vacant building?

Yes, after process. Washington's unfit-buildings statute allows an order to repair, close, or demolish once a building is found unfit, with notice, a hearing, and appeal rights. Cities avoid it because they rarely recover the cost. Far more common: the city secures the building, bills the owner, and records a lien, covered in what happens if you ignore a code violation.

Is a vacant building the same as a condemned house?

No. Vacant means unoccupied. Condemned means the city has formally found the structure unfit and barred occupancy. A vacant building can be structurally sound; a condemned one cannot be legally occupied until repaired and re-inspected. The trail for both is in how to find condemned houses.
