Initial analysis

The four-story multi-family residential building at 23-25 Balboa Street in San Francisco's Inner Richmond neighborhood, owned by Ma Cheng and Yang Jing, was built in 1908 and has undergone significant transformations, most notably between 2008-2011. The most substantial renovation occurred in 2008 when the property was converted from a single-family dwelling to a two-unit building, including a three-story horizontal and one-story vertical addition over the existing garage, with a construction cost of $200,000. This major renovation was followed by comprehensive upgrades in 2011, including the installation of a new fire sprinkler system ($33,500), bathroom reconfigurations on all floors ($10,000), and extensive plumbing work involving nine bathrooms, two kitchens, and various utility installations. The building received necessary safety upgrades including three new 200-amp electric meters, though these permits are currently marked as expired.

Since the major renovations, the building's history has been relatively stable, with most incidents recorded through 311 calls relating to street maintenance, parking violations, and the occasional noise complaint. Notable recent concerns include a June 2024 report of furniture debris and a January 2024 complaint about driveway blockage, though both were promptly resolved. The property's infrastructure improvements from 2008-2011 demonstrate a significant investment in safety and modernization, including comprehensive plumbing and electrical upgrades, though some permits are marked as expired and may require follow-up verification. While the building has experienced typical urban maintenance issues such as sidewalk cleaning needs and parking enforcement matters, these appear to be general neighborhood concerns rather than building-specific problems.

Risk rating

How 23-25 Balboa 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

Grade A–B — Low risk

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

Grade C — Moderate risk

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

Grade D–F — High risk

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

Number of floors

Building height affects maintenance complexity and is one of the size signals the model uses.

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

Estimated permit spend (past 7 years)

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

2026
Planning Record Jan 08
COMPLAINT CLOSED. Duplicate complaint to Case No. 2025-008989ENF. No violation found. COMPLAINT SUBMITTED: Subject: Complaint Regarding Unpermitted Group Housing Use at 23–25 Balboa Street (Pi Kappa Phi Fraternity) Dear Code Enforcement Officer, I am writing on behalf of concerned neighbors regarding the property located at 23–25 Balboa Street (Parcel# 1643051). The building is currently occupied and operated as a fraternity house by Pi Kappa Phi, affiliated with the University of San Francisco. This property is operating as a fraternity house affiliated with the University of San Francisco without the required Conditional Use Authorization (CUA). Although the building is permitted only as a two-unit dwelling, its current use constitutes Group Housing as defined by the Planning Code, which explicitly includes fraternities and sororities (Planning Code § 890.88). In an RM-2 zoning district, group housing is generally permitted, but a CUA is mandatory when the use is tied to an educational institution, as in this case. The structure has a building area of approximately 4,764 sq ft on a 2,495 sq ft parcel. While group housing density controls suggest that between 6 and 12 bedrooms may be allowable in this zoning district, the property reportedly contains 9 bedrooms. Thus, while the building’s bedroom count may fall within density parameters, the current fraternity use appears unpermitted in the absence of a required Conditional Use Authorization. In addition to the lack of proper authorization, there are ongoing concerns from surrounding neighbors regarding the number of men living in the house at any given time, often well above what the permitted two-unit status would allow. This raises questions of illegal conversion, occupancy, and compliance with Housing and Building Code standards. For these reasons, I respectfully request that the Planning Department investigate whether the fraternity’s current use of 23–25 Balboa Street is consistent with its permitted status, and if not, initiate appropriate enforcement actions to bring the property into compliance. Thank you for your attention to this matter. Sincerely, Concerned Neighborhood Coalition  Correspondence Email: [email protected]
