In December 2017, Andreu Osika and his wife Aleksandra Kenar moved into a freshly renovated house on Nevada Street in Bernal Heights. Six weeks later, Osika walked into his bathroom and found sewage backing out of the shower drain. The decades-old ceramic sewer line beneath the house had disintegrated, and what started as a $6,000 plumbing fix unraveled into major structural defects in the foundation and throughout the home, an ordeal that eventually cost the couple at least $650,000. The renovation that hid those problems had been inspected by a city employee who later went to prison for taking bribes.
That house is not an isolated bad-luck story. It is one thread in a Department of Building Inspection corruption case that swept up a director of Public Works, a former president of the city's Building Inspection Commission, and a senior building inspector, and the fallout has a specific bearing on hillside neighborhoods like Bernal. If you are preparing to sell a Bernal Heights home this year, the permit history behind any addition, deck, or slope retrofit deserves as much attention as your comps.
Why a corruption case from 2020 still matters to your listing
Mohammed Nuru, the former director of San Francisco Public Works, was arrested by federal agents in January 2020, and the investigation that followed reached deep into the Department of Building Inspection. Rodrigo Santos, a structural engineer who had served as president of the city's Building Inspection Commission, pleaded guilty to bank fraud, honest services fraud, and tax evasion, and admitted to stealing $775,000 from his own clients. He was sentenced to 30 months in prison, ordered to pay the city nearly $122,000 for audit costs, and in 2025 settled a related civil suit for $1.425 million. Bernie Curran, a senior DBI inspector, pleaded guilty to bribery after admitting he accepted $260,000 from a developer to pay off a personal mortgage.
None of this is ancient history for anyone selling in Bernal. Both Santos and Curran worked on renovation and construction projects across the city, and the properties connected to them did not disappear when the men went to prison. Their sign-offs are still sitting in permit files that title companies, lenders, and buyer's agents can pull today.
What the city's own audit tells you about hillside lots
After the arrests, San Francisco auditors began reviewing more than 5,400 buildings connected to work by Curran and Santos to check whether the corruption had produced actual safety issues. The audit split properties into tiers, and the second tier singled out any property connected to either man that also sat within what the city called a slope protection zone, meaning the lot was in a landslide zone, on a steep slope, or subject to construction that could affect slope stability. That is not a small technical footnote if you own property in Bernal. The neighborhood is built across a hill, with distinct north-slope, south-slope, and west-slope pockets, and hillside construction, retaining walls, and view decks are exactly the kind of work that lands a property in that review category.
The findings from that audit were not catastrophic. Investigators reported no imminent life-safety hazards at the properties they had reviewed by that point, but they did find incomplete trade permits, missing job cards, expired permits needing renewal, and plan reviews that needed a second look. More than 4,000 properties were still awaiting review when that reporting came out. The takeaway for a Bernal seller is not that your home is suspect. It is that a thin or incomplete permit file is common enough in this specific pocket of the city that a serious buyer's agent will check for it, and you want to know what is in that file before someone else finds it during their inspection contingency.
The paperwork that actually protects you
California's Transfer Disclosure Statement and Seller Property Questionnaire already require you to disclose known unpermitted work, and that obligation does not go away if the work was done by a previous owner or if you are selling as-is. What has changed is how much detail the law now demands from anyone who has recently taken title.
Under California Civil Code section 1102.6h, the so-called Flipper Disclosure Law that took effect for offers accepted on or after July 1, 2024, a seller of a single-family home who accepts an offer within 18 months of taking title has to disclose any contractor-performed room additions, structural modifications, or repairs, name the contractors who did the work, and deliver the related permits or permit applications. In a neighborhood where renovate-and-resell has been a common path to market, this rule puts real weight behind the permit file rather than a seller's memory of what was done.
Since January 1, 2026, California sellers have also had to disclose the presence of gas-powered appliances and whether tobacco or nicotine products have been used inside the home, additions to the standard disclosure package that apply regardless of neighborhood. None of these forms replace a buyer's own inspection, but together they mean the permit history you can document upfront does more work for you than it used to.
Reading Bernal's price by slope, not by neighborhood median
Bernal Heights does not price like a single market, and the spread in recent sales data makes that obvious. In the three months ending April 2026, the median sale price across the neighborhood sat at $1.6 million with a median price per square foot around $1,120, according to public listing data. Two-week snapshots from local brokerage reports in July and August 2026 put closed sales anywhere from $728,371 to $6 million in the same short window, with price per square foot running closer to $1,220 to $1,230 and homes typically finding a buyer in 14 days.
That range is not noise. It reflects the same slope geography that puts certain properties inside the city's audit review zone. North-slope homes between the park and Precita often carry downtown view premiums, east-facing south-slope homes look toward the Bay, and prices generally step down as you move south from Cortland Avenue and east from Banks Street, with the Holly Park pocket in the southwest holding value better than blocks further southeast. A buyer's agent pricing a home in this neighborhood is not just comparing square footage. They are comparing which slope the lot sits on, what work has been done to it, and whether that work has a clean paper trail, because on a hillside lot, an unpermitted retaining wall or a deck built without a slope stability review is a different kind of risk than a garage conversion in a flat part of the city.
Five records worth pulling before you list
- A full permit history for the property from the Department of Building Inspection, not just the permits you personally pulled, going back through prior owners if the house has changed hands recently.
- Documentation on any retaining wall, slope grading, or hillside excavation work, including whether it required a special inspection or engineer sign-off.
- Contractor names and permit numbers for any room addition, structural change, or major repair completed within the last 18 months, which California now requires you to name explicitly under the Flipper Disclosure Law.
- A current sewer lateral inspection, given how often older ceramic lines in Bernal's housing stock show up as a surprise during escrow.
- Any notices of violation, open complaints, or expired permits tied to the address, which a title search or a DBI records request will surface even if you were not the one who caused them.
Frequently asked questions
If the unpermitted work was done by a previous owner, do I still have to disclose it? Yes. California's disclosure standard is what you know or reasonably should know, not who did the work. If you are aware that an addition or renovation lacks proper permits, that goes on the Seller Property Questionnaire regardless of when it happened or who was living there at the time.
Does the Flipper Disclosure Law apply if I've owned the home for years but just finished a renovation? The 18-month clock runs from when you took title to when you accept an offer, not from when the renovation finished. If you bought the home more than 18 months before listing it, the specific contractor-naming requirement under Civil Code 1102.6h does not apply, though your general disclosure obligations for known defects and unpermitted work still do.
Will a thin permit file actually cost me money, or is this an overcorrection? It can go either way. A buyer's lender may hesitate to count unpermitted square footage toward the appraised value, and title insurers commonly exclude unpermitted-structure risk from standard coverage. A clean, well-documented permit file does not just avoid a problem. It gives your agent something concrete to put in front of a buyer's agent during a multiple-offer negotiation, which matters in a market where homes are still moving in about two weeks.
Bernal Heights rewards sellers who treat the permit file as part of the pricing conversation, not an afterthought handled during escrow. If you are weighing when to list or want a second read on what your specific slope and street are commanding right now, Russell Pofsky can walk through the permit history, the comps that actually apply to your block, and a pricing strategy built around both.
