What to check before you buy a house in Vallejo

Most of what goes wrong in a house purchase is not hidden. It is written down somewhere — in a recorded document, on a tax bill, in a permit file — and nobody looked. I read those things before my clients write an offer, and the four below are the ones that turn up most often in Vallejo.

None of this is a reason not to buy a house here. It is a reason to know what you are buying before you are in contract, when you still have leverage, rather than after, when you don't.

1. The sewer lateral rule that changed in July 2025

This is the one almost nobody knows about yet, including some sellers who are about to be surprised by it.

The Vallejo Flood and Wastewater District — note: the District, not the City — adopted Ordinance 2025-73, effective July 1, 2025. If a property is for sale and ten or more years have passed since the private upper lateral was built or replaced, an inspection is required. The buyer, the seller, or either agent arranges it with a private contractor, and the report has to reach the buyer, the seller and the District at least ten days before escrow closes.

Here is the part people get wrong, in both directions. You are not required to repair or replace anything. The inspection is informational. A failed scope does not block the sale and does not obligate the seller to fix the line. It simply means both sides now know, which is the entire point. And if you do decide to replace it, the District currently offers reimbursement of up to $3,500.

Exempt: laterals installed or replaced under District permit within ten years of the sale, condominiums, and mobile homes in parks. For most of Vallejo's housing stock — which skews considerably older than ten years — assume it applies.

Practical advice: get the camera scope done early, not on day ten. A lateral problem discovered with three weeks left is a negotiation. The same problem discovered with three days left is a scramble.

2. PACE liens, which ride on the property tax bill

PACE financing pays for solar, windows, HVAC and similar upgrades, and it is repaid as a line on the property tax bill rather than as a mortgage. That matters to a buyer for one reason: it stays with the house. You inherit the payment.

California's standard seller questionnaire asks about this directly. It is still worth checking yourself. Earlier this year I reviewed the disclosure package on a Bay Area listing that was already on the market and found more than $32,000 of PACE financing against the property — on a form where that exact question had been answered "No."

I don't think that was dishonesty. I think it is genuinely common for people not to know what is recorded against their own house, particularly if the work was financed years ago by a contractor who handled the paperwork.

Two places to look: the actual property tax bill, where PACE shows up as a special assessment rather than in the base tax, and the preliminary title report, which you should read rather than skim.

3. Permit history — and it's public

The City of Vallejo's building records are searchable online through eTRAKiT, from the Building Division. Anyone can look. You don't need to be the owner and you don't need to file a records request.

One quirk that defeats most people on the first try: when searching by address, leave the street type off. Enter 1301 Georgia, not 1301 Georgia St. Including it tends to return nothing, which looks exactly like a house with no permit history.

What you are looking for is less "were there permits" and more two specific patterns: permits that were pulled but never finaled, and work that plainly exists in the house with no permit at all. Walk the house with the bedroom and bathroom count from the tax roll in your hand. If you counted four bedrooms and the county thinks there are three, something happened here and you want to know what.

4. What unpermitted work actually costs you

People treat unpermitted square footage as a paperwork nuisance. It is usually a money problem:

The appraiser may not count it. If the converted garage isn't permitted living space, it may not appear in the square footage the appraisal is built on — which can mean the house doesn't appraise at what you agreed to pay.

Your lender may balk, particularly on anything structural or any addition that reads as a second unit.

Your insurer may not cover it, and you may not learn that until you file a claim on it.

Legalizing it becomes yours the moment you close, along with whatever the current code requires, which is rarely what the code required when the work was done.

What to do with any of this

Find it early and it is a negotiation — a price adjustment, a credit, a repair, or a decision to walk with your deposit intact. Find it late and it is either an argument or a bill.

The checks above cost a camera scope and an afternoon of reading. That is a genuinely small amount of money and time set against the largest purchase most people make.

This is general information for Vallejo buyers and sellers, not legal, tax, engineering or lending advice. Requirements change and vary by property — confirm current rules with the Vallejo Flood and Wastewater District, the City of Vallejo Building Division, and your own escrow officer, inspector and lender.
