coastal demand meets limits on collectible growth.

Coastal and inland ZIP-index medians

These selected county sets use only September 2026 observations. They include inland portions of coastal counties. They are analytical comparisons, not six official regions covering all California or commute recommendations.

Bay Area–Sacramento and LA–Inland Empire gaps

The Bay Area set is $1,142 above the Sacramento set per month ($13,704 annualized). Los Angeles + Orange is $357 above the Inland Empire ($4,278 annualized). Those are differences between geographic benchmarks, not the savings from moving an identical home.

San Francisco is only one part of the nine-county Bay Area; Los Angeles city is only part of the LA + Orange set. Check an actual work trip and lease before treating lower rent as a lower household budget. MTC’s commute-pattern resource gives regional context; the worksheet below uses your own travel assumptions.

Monthly amounts are rounded for display; annual gaps use the unrounded median difference. The comparisons summarize tracked ZIPs, not matched apartments.

California cities: find the local ZIP directory

The table links all 82 currently eligible city pages. It groups Zillow’s postal-city labels and requires at least three ZIPs; a mailing-city group is not a surveyed municipal rental market.

Median and mean of included ZIP indices, whole dollars, equal ZIP weights. City samples have different month ranges. Source: shared ZIP data / Zillow Research. Use the regional table for the common-month cut.

Find a ZIP and its actual observation month

Filter by ZIP, postal city or county. The actual observation month is shown with each record. Zillow covers locations with sufficient data, not every California ZIP.

The separate ZIP and bedroom lookup supplies HUD references. Those are not bedroom-specific ZORI asking rents or approval of a particular lease.

Does lower rent survive the extra trip?

A rent discount is the starting budget for added travel, parking and utilities. Enter two real offers rather than the regional indices. Geography changes the search area; the lease and your daily routine determine the household result.

Check the home before using the benchmark

1. Match the lease model. Separate whole homes from rooms, furnished stays and seasonal rentals. A coastal all-size index does not establish a year-round apartment comp.
2. Match bedrooms and daily use. Compare usable space, condition, parking, cooling and access. Price tenant-paid utilities explicitly. Nearby ZIPs can contain different buildings.
3. Normalize the first lease. Compare the same lease length and concessions. Keep refundable deposits and moving cash separate from rent; budget full-rent months even if a concession lowers the average.
4. Check address and tenancy. An asking-rent index does not establish existing tenants’ rent or a lawful increase. Start with California Attorney General tenant guidance and the applicable local rules.

Bedroom rents and growth need different evidence

The shared table stores one latest available all-size observation per ZIP. It cannot support one-bedroom or two-bedroom asking-rent averages, matched-period growth or a forecast. Comparing samples with different dates is not a time series.

Investors can test a unit-matched rent and downside case in the rental cash-flow calculator. The California cap-rate report adds transaction and underwriting context. For your own home, use the California rent-versus-buy directory. The county market directory and investment screening answer related questions with different measures.

Read-only freshness audit, October 20, 2026: the shared database’s 953 eligible state ZIPs matched the upstream September 2026 observation month. No upstream ZIP was missing from storage and no matched stored observation lagged the source. Storage also held 83 older June–August observations outside the current sample; 83 stored ZIPs were absent from the downloaded file. These are dated audit counts, not a promise of future coverage. The lookup’s displayed dates and counts follow the shared validated refresh. Quarterly apartment research elsewhere on this page uses its own named sources, periods and cohorts.

Sources, dates and coverage

Source and weighting: Zillow Research, ZIP-level smoothed all-home ZORI. Its repeat-rent methodology explains internal weighting and controls for changing stock. Our additional ZIP aggregation is not Zillow’s official statewide series or a household-weighted average.

Shared refresh: the ZIP-index tables above come from the same database as our rent directories. The central pipeline validates and publishes source versions, retaining prior observations for provenance. Non-current records are excluded from rent estimates after publication. Successful scheduled ingestion invalidates the rent-page caches. This page has no independent rent snapshot or manual rent overrides.

Limits: tracked ZIPs are not all ZIPs, households or active listings. Coverage and housing mix can change rankings. This page does not trim high values from the eligible sample; check listings before using an extreme as a comp. Annualized geographic gaps do not predict moving savings or returns.

Visuals: licensed photographs reuse our California research library, with dates, photographers and adaptation notes beside each image. Original graphics have an HTML table or visible arithmetic. No generated local scenes or external expert review are claimed.
