Initial analysis

The two-unit residential building at 81 Carl Street, located in the Parnassus/Ashbury Heights neighborhood, has undergone significant recent renovations and improvements in 2024. The property, owned by Ronald S. Armada, has completed major infrastructure upgrades including a $32,000 reroofing project, installation of two direct vent gas inserts, a new furnace and ductwork system, and an electrical service panel upgrade to 200 amps serving both units. These improvements began in early 2024 and continued through May 2024, demonstrating proactive maintenance of the nearly 120-year-old structure.

The building has experienced a series of parking enforcement issues in late 2024, with multiple complaints (ten reported incidents between October and December 2024) regarding vehicles blocking driveways, resulting in several citations. Additionally, the owner completed a tenant buyout at the adjacent 83 Carl Street address in June 2024, involving three tenants and totaling $80,300. Historical records show the property had completed earlier improvements including window and door replacements, and built-in cabinet installations in 1986, while a re-roofing project from 1990 was listed as expired. The extensive 2024 renovation work, particularly the upgrade to modern heating systems and electrical infrastructure, suggests significant investment in improving the building's systems and amenities.

Risk rating

How 81 Carl 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.

Neighborhood percentile

Out of 526 buildings in this neighborhood, 37 are predicted to be safer.

12-Month severity forecast
No violation 77.1%
Moderate concern 12.2%
Severe concern 10.7%
