A permit filed August 3 for a single-family dwelling near the ocean end of 45th Avenue details the deletion of a ground-floor bedroom, a hallway narrowed to under four feet, and a tub added upstairs — quiet interior changes, and a notation in the filing that raises questions about how many households the address actually holds.

At 1229 45th Avenue, a few blocks from the ocean on one of the Sunset's quieter residential stretches, a permit filed this month documents a rearrangement of interior space: one bedroom removed from the ground floor, the hallway narrowed to 3 feet 9 inches, a tub added to an existing upstairs bathroom.

The filing — permit 202608035940, logged with the Department of Building Inspection on August 3 — carries an estimated cost of $1, the placeholder figure that appears when a permit revises prior-approved work rather than authorizing a new project from scratch. It amends two earlier permits, 202606189000 and 202606153217, both filed in June. San Francisco's Over-the-Counter track, the city's streamlined process for minor interior residential remodels including layout changes and wall removal, handles these kinds of revisions same-day or near-same-day at the Permit Center — no additional neighborhood notification, no extended review required.

What the permit describes, in DBI's compressed notation, is a home reorganizing itself across two floors. The ground-floor space — labeled "unit 1" in the filing — loses a bedroom; the hallway running through it will measure under four feet wide. Upstairs, in "unit 2," the existing bathroom gains a tub. The property is listed in city records as a one-family dwelling, but the permit's own floor-by-floor notation points to a home that already functions as something more layered: two distinct spaces stacked in a structure the city classifies as single-family. Whether the current changes formalize that arrangement or begin to unwind it, the permit doesn't say.

DataSF records show 12 eviction notices filed in Sunset/Parkside in the last 90 days — including one on the 1400 block of 39th Avenue, filed July 29, and another on the 1200 block of La Playa Street, filed July 20. Residents have logged 506 requests through 311 in the past week. That's the texture of a dense residential district running from the park to the ocean, block after block of similar-looking homes where interior arrangements shift considerably without the façade ever changing.

Someone walking past 1229 45th Avenue won't see much from outside. On a floor plan that will look different once the contractors are done, there is now one fewer bedroom.
