Alteration & Repair Dominates 91403, Los Angeles — June 2026

Renovation, not new construction, defines what got built on paper in 91403 this window. The Sherman Oaks ZIP filed mostly the kind of permit that keeps an existing house standing and updated — Alteration & Repair work on one- and two-family dwellings — rather than ground-up homes. That single category carried the ZIP, and reading why tells you who is actually working these streets.

Every figure below is a slice of the Los Angeles sealed snapshot for the May 11 – June 9, 2026 reporting window. Scope: residential building permits (single-family and small multi-family); commercial and sub-trade permits are excluded at ingest. This is not a count of all construction permits issued in each city. A sealed snapshot is a point-in-time capture of public permit records, hashed and stored before any analysis runs, so the numbers cannot drift after the fact.

This edition is cross-sectional: it describes one 30-day window for 91403 and makes no claim about trend, momentum, or how the ZIP compares to its own past — that history does not exist in this series yet.

What Sherman Oaks Filed in 91403

The ZIP top category is Bldg-Alter/Repair / 1 or 2 Family Dwelling, surfaced in plain language as Alteration & Repair, with 16 permits in 91403. That is half of the ZIP total of 32 permits. The deep read below works through what that label actually authorizes, why it dominates a built-out residential pocket, and what the few non-alteration filings imply about the rest of the market here.

Alteration & Repair — the category carrying the ZIP

An Alteration & Repair permit on a one- or two-family dwelling is the workhorse of an established neighborhood. It covers changes to an existing structure that do not add new dwelling units or, usually, new footprint: re-wiring, re-plumbing, a kitchen or bathroom remodel, foundation repair, a new roof structure, window and door reconfiguration, seismic retrofits, and interior reframing. In Los Angeles these come through the Department of Building and Safety as the residential alteration permit type, and they are pulled by homeowners, general contractors, and specialty trades alike.

When 16 of 32 permits in 91403 are Alteration & Repair, the story is maintenance and modernization of housing that already exists. Sherman Oaks is a built-out hillside-and-flats neighborhood with limited vacant land, so the dominant economic activity is improving the housing stock rather than expanding it. That mix favors remodel contractors, electricians, plumbers, and roofers over tract builders.

Alteration & Repair on a one- or two-family dwelling authorizes remodels and repairs to a home that already exists — no new dwelling unit.

What the citywide category mix adds

The ZIP sits inside a citywide pattern with the same shape. Across Los Angeles, the top residential category is Bldg-Alter/Repair / 1 or 2 Family Dwelling at 2,486 permits, followed by Bldg-Addition / 1 or 2 Family Dwelling at 422 permits and Bldg-New / 1 or 2 Family Dwelling at 359 permits. Alteration dwarfs both addition and new build at the metro level, and 91403 mirrors that — renovation first, additions and ground-up far behind.

An Addition permit means new square footage on an existing home — a second story, a bumped-out bedroom, an ADU envelope. A New permit is a ground-up dwelling. The fact that both trail alteration so heavily, citywide and by implication in 91403, tells suppliers and contractors that the near-term work here is interior and repair-driven, not framing lumber and foundations for new houses.

ZIP 91403 Permit Activity, May 11 – June 9, 2026

The headline slice for the ZIP is small in count and modest in valuation — consistent with a neighborhood doing many ordinary remodels rather than a few showpiece builds.

A median permit valuation of $5,250 is the center of gravity for the ZIP: half the filings carry a stated value at or below that figure. Read alongside a window total of $0.7M, that low median says the typical 91403 job is a small, defined scope — a service upgrade, a bathroom, a repair — not a gut renovation. A handful of larger jobs can still lift the dollar total without moving the median, which is exactly how a remodel-heavy ZIP behaves.

The 91403 median permit valuation was $5,250 — the typical filing here is a small, defined remodel or repair, not a gut job.

For a contractor, that median is a qualifying signal. It points to ticket sizes and job types that fit a remodel or trade business rather than a production builder, and it flags 91403 as a steady-volume, small-job neighborhood worth a standing presence.

How 91403 Compares Among Los Angeles ZIPs

The same sealed snapshot ranks every Los Angeles ZIP. Placing 91403 next to the busiest residential ZIPs and the citywide row shows how a quiet, remodel-driven pocket reads against the metro's volume leaders.

The contrast is stark. 90272 alone recorded 388 permits worth $66.2M, a different market entirely — high-value coastal and hillside construction. 91403 with 32 permits and $0.7M is at the calmer end: low count, low median, repair-led. Neither is "better"; they are different jobs. A high-end remodeler or builder chases the 90272 and 90049 valuations, while a volume trade or service business may prefer the steady, predictable cadence of ZIPs like 91403, where the work is frequent and the tickets are small.

Citywide context anchors both ends. With 4,042 permits and $201.2M in reported valuation across the window — and a citywide median of $7,000 against a max single permit of $4,000,000 — Los Angeles spans pure repair tickets up to multimillion-dollar projects. The citywide lower quartile of $2,500 and upper quartile of $35,000 frame how wide that spread runs, and 91403's $5,250 median lands inside the lower half of it.

Methodology

These figures come from the Los Angeles Department of Building and Safety via data.lacity.org (Socrata), cut to ZIP 91403. All figures are computed directly from US Tech Automations' sealed daily permit snapshots; nothing is estimated, modeled, or extrapolated. The ZIP view is a straight slice of the same citywide snapshot — no separate collection, no different source.

Citywide, valuation is reported on 3,779 of 4,042 permits, a coverage of 93.5%; permits without a stated value are counted but excluded from valuation math. That coverage applies to the metro totals the ZIP sits within. We never invent a missing value or write a zero where the source is silent.

Our pipeline runs the same four steps every day:

1. Collect. Pull the day's residential permit records from the Los Angeles Socrata endpoint, filtered to the residential permit types in scope.

2. Normalize. Standardize fields — category labels, valuation, ZIP — and drop commercial and sub-trade records at ingest.

3. Seal daily. Hash each day's records and store them append-only, so the snapshot cannot change after capture.

4. Aggregate. Sum and rank across the May 11 – June 9, 2026 window, then cut the citywide result down to the 91403 slice you see here.

Because the window is a single 30-day cross-section, this report makes no month-over-month or year-over-year claim. We publish what the sealed snapshot holds and nothing beyond it. The companion Los Angeles permit report covers the citywide view in full, and our permit prediction ledger documents how these sealed snapshots are later scored against public outcomes.

Frequently Asked Questions

Q: Is 91403 only construction work?
A: No. The 91403 count of 32 covers residential building permits in scope — single-family and small multi-family alterations, additions, and new builds. Commercial and sub-trade permits are excluded at ingest, so this is not every permit issued in the ZIP.

Q: Why does the 91403 median look so low?
A: The median permit valuation is $5,250 because most filings here are small, defined jobs — repairs and remodels rather than ground-up homes. A low median with a modest $0.7M total is the signature of many small permits plus a few larger ones.

Q: What does the top category actually cover?
A: The top category is Bldg-Alter/Repair / 1 or 2 Family Dwelling, shown as Alteration & Repair, with 16 permits. It authorizes changes to an existing home — remodels, re-wiring, re-plumbing, roofing, retrofits — without adding a new dwelling unit.

Q: Who pulls these permits in 91403?
A: Homeowners and the contractors and trades they hire — general remodelers, electricians, plumbers, and roofers. With Alteration & Repair leading at 16 permits, the active parties are renovation and service businesses working existing Sherman Oaks housing.

Q: How does 91403 compare to the busiest LA ZIPs?
A: It is quieter. 91403 filed 32 permits worth $0.7M, while 90272 recorded 388 permits worth $66.2M. Citywide, Los Angeles logged 4,042 permits worth $201.2M, so 91403 is a small, repair-led slice of a large market.

Put Permit Data to Work

A ZIP like 91403 is a working signal for several trades at once. Contractors qualify neighborhoods by category mix and ticket size — the 16 Alteration & Repair filings and the $5,250 median together say "steady small-job remodel territory." Suppliers time inventory to the work types behind those permits; lenders read renovation demand from valuation; real estate agents treat alteration activity as a pre-listing tell that owners are investing before they sell.

The constraint is never the public data — Los Angeles publishes it. The constraint is turning a daily firehose of permit records into a monitored, routed, contactable stream before a competitor does. We build automations that watch the live Los Angeles permits feed, filter to the ZIPs and categories a business cares about, and route each fresh filing into lead lists and outreach drafts — the same sealed-snapshot discipline shown in our permit report, put to work on a single neighborhood.

Two neighboring San Fernando Valley ZIPs follow the same remodel-led pattern worth comparing: the Valley Village permit slice and the Northridge permit slice. If you want permit signals like these monitored and routed automatically for your market, see our real estate AI agents.
