Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

Rent & eviction protection

Is 633-635 Castro St rent-controlled?

San Francisco's Rent Ordinance caps rent increases and provides eviction protection for most residential units built before 1979 with 2+ units. Here's how this building scores.

Built before 1979
Built 1910
2 or more units

Property type
Multi-Family Residential

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

Statewide backstop · AB 1482

California Tenant Protection Act of 2019

Even when a building isn't covered by local rent stabilization, the statewide Tenant Protection Act (AB 1482) may still apply. It caps annual rent increases and requires the landlord to state a legal reason to end most tenancies.

15+ years since occupancy
Built 1910
Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
Local rent control likely takes priority. This building appears to fall under the local ordinance above, which is stronger than AB 1482. Where a local just-cause ordinance applies, its rules govern instead of the state cap.

AB 1482 does not apply to single-family homes and condos unless owned by a corporation, REIT, or an LLC with a corporate member; to owner-occupied duplexes; or to deed-restricted affordable housing. The Act is in effect until January 1, 2030. Not legal advice — see the California landlord–tenant guide.

Initial analysis

The three-unit multi-family residential building at 633-635 Castro Street, owned by Michael Sindicich, was constructed in 1910 and is classified as a TIC building with four units or less. The property has undergone several significant structural improvements in recent years, with the most recent work completed in January 2024 involving reinforcement of the retaining wall at the southeast corner. Previous retaining wall improvements were made in 2018, including modifications to increase its height and width. The building has seen comprehensive maintenance and modernization, including a major renovation in 2017 that involved removing a bearing wall between the kitchen and living room in the second-floor unit, updating bathrooms and kitchens, and replacing the rear staircase, all totaling approximately $51,000 in improvements. Other notable improvements include window replacements in 2006, interior wall alterations in 2009, and plumbing and electrical upgrades in 2019 for kitchen and bathroom remodeling.

The building's maintenance history indicates attention to safety concerns, particularly regarding fire safety and structural integrity. While there were multiple violations noted in 2005 related to interior surfaces, fire safety, stairs, and self-closing doors, these were all addressed and abated by August 2005. A 2009 complaint about missing fire resistive surfaces was resolved by December 2009. The property has maintained active responses to safety concerns, with regular inspections and prompt attention to violations. The building's history includes some infrastructure challenges, such as dry rot on rear stairs (2005), electrical issues (2005), and insulation concerns between floors (2005), all of which appear to have been addressed through subsequent repairs and upgrades. The most recent retaining wall reinforcement work in 2024 suggests ongoing commitment to maintaining the building's structural components, particularly those related to the hilly terrain of the Castro neighborhood.

Risk rating

How 633-635 Castro St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Lower risk — safer than most nearby

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Typical — about average for the neighborhood

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Higher risk — riskier than most nearby

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
39thpercentile

Out of 1278 buildings in this neighborhood, 780 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.
