Alteration & Repair Dominates 91345, Los Angeles
Alteration and Repair dominates the residential permit picture in ZIP 91345 during the 30 days ending June 9, 2026. Of the 15 residential building permits filed in this Mission Hills ZIP over that window, 12 fell into the "Bldg-Alter/Repair / 1 or 2 Family Dwelling" category — the raw source label from the Los Angeles Department of Building and Safety. The remaining three permits round out a small but consistently renovation-focused slice of the broader Los Angeles metro permit picture.
A residential building permit is the city's written authorization for regulated construction or modification work on a single-family or small multi-family structure. This report covers that scope only; commercial and sub-trade permits are excluded at ingest, and the figures here represent a slice of the Los Angeles metro's sealed daily snapshot, not all construction in the city. Every figure is drawn verbatim from our sealed permit ledger — nothing is estimated, modeled, or extrapolated.
The $6,000 median valuation for 91345 and the $0.3M total declared valuation for the window place this ZIP in the middle of its peer band: meaningfully above the lowest-valuation peers, below the higher-scope clusters. That positioning reflects a renovation market where the typical project is substantive enough to require a permit but anchored firmly in the moderate-cost range.

What Is Getting Built in 91345: A Deep Dive on Alteration and Repair
The Dominant Category in Depth
The LADBS source label is "Bldg-Alter/Repair / 1 or 2 Family Dwelling" — shortened in this pipeline to the friendly label Alteration and Repair. It is the single largest residential permit category in Los Angeles as a metro, accounting for 2,486 of the city's 4,042 residential permits during the same window. In 91345, 12 of 15 permits fell here, a concentration that is consistent with the metro pattern and reinforces what the category itself suggests: this is a market of owners and landlords investing in existing structures rather than building new ones.
What does an Alteration and Repair permit actually require in Los Angeles, and what kinds of jobs trigger it? The category is intentionally broad, capturing any scope of residential work that modifies an existing single-family or two-family structure without adding net new square footage or creating an additional dwelling unit. Within that boundary, the types of projects are numerous:
Seismic retrofitting. Los Angeles has an active mandatory retrofit ordinance for soft-story apartment buildings, but single-family homes on raised wood foundations are also candidates for voluntary seismic improvement. The standard "cripple-wall bracing and bolting" scope — anchoring the mudsill to the foundation and bracing the cripple walls — requires a building permit even when the visible scope of work is limited to the crawlspace. In a ZIP like 91345, with a substantial stock of pre-1980 single-family homes, seismic retrofits are a recurring driver of Alteration and Repair permit activity.
Roof replacement with structural components. A simple re-roofing job using identical material and no structural work often falls under a separate roofing permit. But when the scope involves replacing deteriorated sheathing, repairing or sistering rafters, or addressing ridge-board damage, it crosses into building-permit territory under Alteration and Repair.
Kitchen and bathroom renovations. A cosmetic kitchen update — new cabinet faces, a new sink on existing plumbing rough-in — may not require a building permit. But when the renovation involves moving walls, changing the plumbing rough-in location, adding a window or door opening, or altering load-bearing framing, the project requires an Alteration and Repair permit in addition to whatever sub-trade permits the plumber and electrician pull independently.
Structural repairs. Homes with deteriorated posts, sagging girders, foundation issues, or earthquake-damaged framing require permitted structural repair work. These projects can range from a single beam replacement to a full foundation repair, all captured under the same category label.
HVAC and mechanical system replacements. When an HVAC replacement requires structural access — cutting through joists, enlarging duct chases, or modifying the building envelope — it may trigger a building permit in addition to the mechanical permit. In older homes with original ductwork in unusual configurations, this is common.
The $6,000 median for 91345 is consistent with the lower end of the renovation scopes listed above. Structural-only scopes such as a seismic retrofit on a cripple-wall bungalow tend to carry modest declared valuations before any cosmetic finish work. A kitchen or bath renovation with structural involvement can run higher, but when the structural component is modest, the declared valuation for the building permit portion alone stays on the lower end of the range.
"12 of 15 permits in ZIP 91345 were Alteration and Repair — the same category that dominates the Los Angeles metro as a whole, concentrated here in a mid-size renovation market." — computed from the sealed permit snapshots, May 11 – June 9, 2026
What the Remaining Three Permits Tell Us
The display set for 91345 confirms the top category count of 12. The remaining three permits fall into other residential building categories; the display set does not enumerate them individually at the ZIP level. At the metro level, the next categories are Additions (422 permits) and New Construction (359 permits). Whether any of the three non-Alteration permits in 91345 represent additions or new builds cannot be confirmed from the sealed ZIP-level data — only the Alteration and Repair concentration of 12 is sealed at the ZIP level in this edition.
Metro Category Context
| Metro Category | Count |
|---|---|
| Bldg-Alter/Repair / 1 or 2 Family Dwelling | 2,486 |
| Bldg-Addition / 1 or 2 Family Dwelling | 422 |
| Bldg-New / 1 or 2 Family Dwelling | 359 |
| All other residential categories | — |
| Total metro permits | 4,042 |
The metro-level distribution confirms that Alteration and Repair is not just the largest category — it is the dominant one by a substantial margin. Additions and new construction together do not approach it in volume. ZIP 91345's permit mix, with 12 of 15 in Alteration and Repair, mirrors this metro pattern at the neighborhood scale.

Frequently Asked Questions
Q: Does the Alteration and Repair count of 12 include all permit types that involve renovation work?
A: The count of 12 reflects only the LADBS category labeled "Bldg-Alter/Repair / 1 or 2 Family Dwelling" as captured in this pipeline. Sub-trade permits — standalone electrical, plumbing, and mechanical permits — are excluded at ingest. A full renovation project may generate multiple permits across categories; this report counts only the building-permit component, which is one piece of the total permit picture for a given project.
Q: How does the $6,000 median relate to actual project costs in 91345?
A: The $6,000 median is the midpoint of declared valuations for the 15 permits in this window, not an estimate of total project cost. Declared valuation in Los Angeles is the amount the permit applicant reports for the scope covered by that permit — it often reflects the structural or building-permit scope alone, not the full cost of a renovation that also involves separate sub-trade permits. Actual project costs are typically higher.
Q: Why is the 91345 total valuation ($0.3M) different from the 90059 total ($0.8M) when both filed 15 permits?
A: The per-permit median in 91345 is $6,000 versus $6,450 in 90059, and the 90059 pool included some higher-valuation projects that pulled the total up. The $0.3M vs $0.8M difference reflects a distribution difference in the pool, not a difference in count. Both ZIPs filed 15 permits; the project scopes in 90059 were larger on average than in 91345 during this window.
Q: Who should look at this data for 91345 specifically?
A: Contractors working the north San Fernando Valley — Mission Hills, Sepulveda, and adjacent neighborhoods — will find a consistent renovation-permit market here. Listing agents working the area can use recent permit activity to identify improvement-minded sellers. Suppliers serving residential renovation contractors in the Valley can use this data to calibrate territory planning and inventory for repair-tier work.
Q: This is a small slice — 15 permits. How reliable is a median from that sample?
A: The $6,000 median is a direct measurement from the 15 permits in this window, not an estimate or model. It is accurate for what it represents: the midpoint of declared valuations in this sealed set. Small samples are genuinely small — a single high-value project would shift the median noticeably — and this report makes no claim beyond the 15-permit window. Context comes from the metro-level data and the peer band, both of which are larger samples.
Put Permit Data to Work
Three professional audiences find the 91345 permit picture most immediately actionable.
Specialty and general contractors working the north San Fernando Valley can use the consistent Alteration and Repair volume to justify outreach investment in 91345. Fifteen permits in 30 days is a moderate signal — not a high-density target, but enough to make direct outreach and neighborhood marketing worthwhile for contractors specializing in seismic retrofits, roofing, kitchen and bath renovation, and structural repairs. The $6,000 median tells a contractor that the typical scope here is focused and mid-range — a project they can complete efficiently without the overhead of a large-scale renovation.
Listing agents active in Mission Hills and Sepulveda can monitor permit activity as a prospecting signal. Homeowners who complete permitted improvements — especially structural and renovation work with a declared valuation — often transition to the sale market within a relatively short window after the work is inspected and closed out. An agent with visibility into recent permit filings can identify those owners and initiate a conversation grounded in neighborhood market data rather than a cold outreach.
Investors and lenders evaluating north Valley properties can use permit activity as a health indicator for the local housing stock. A ZIP where owners are actively pulling renovation permits is a market where investment in existing structures is ongoing — a positive signal for property condition and maintenance culture, even at the modest per-permit valuations visible here.
US Tech Automations automates permit monitoring for all three of these audiences, pulling daily from the LADBS feed, categorizing new filings by ZIP and permit type, and routing them to contractors, agents, or investors according to their territory and filter criteria. The system can be configured to automate outreach drafting when permits matching specific criteria are filed — removing the need for manual tracking of public data.
