Home appraisals in Montclair

Montclair sits directly on the county line. Its western boundary is Mills Avenue, where Claremont and Pomona in Los Angeles County end and San Bernardino County begins. The city was incorporated as Monte Vista, renamed Montclair, and grew mostly after the Second World War on former citrus land, so much of its housing is postwar single-family tract stock, with small income property near the Montclair Transit Center and Montclair Place. The San Bernardino Freeway, I-10, crosses the north of the city.

Montclair's pockets and eras

Most Montclair homes are single-story postwar and later tract houses on regular lots, built as the former Monte Vista orchard tracts filled in. They differ from one another mainly in additions, garage conversions, lot size and condition, which makes the permit history of each addition the most important fact on inspection day.

Around the Montclair Transit Center, the Metrolink commuter hub, and Montclair Place, the city's regional shopping center, the stock mixes in older duplexes, small apartment buildings and houses divided into units. North of the I-10 the tracts meet the Claremont and Upland lines, and south of it they continue toward Pomona and Chino.

Assessor, appeals board and Mills Avenue

Montclair property is assessed by the San Bernardino County Assessor-Recorder-County Clerk, with formal appeals to the San Bernardino County Assessment Appeals Board through the Clerk of the Board of Supervisors. Across Mills Avenue, similar postwar houses in Claremont and Pomona are assessed by Los Angeles County, heard by a different board, and served by different school districts.

That is why Montclair tax-appeal and review work so often involves the line. A sale on the Los Angeles County side can be valid evidence of Montclair market value, but only with the location difference explained; a board or a reviewer will ask why it was used.

What a reviewer throws out in Montclair

The recurring rejection is a Claremont or Pomona sale across Mills Avenue used for a Montclair house with no location adjustment, or the reverse. The houses may match; the county, the schools and the buyer pool do not, and the report must say so.

A reviewer also rejects a converted garage counted as permitted living area, a duplex compared with single-family sales, and sales pulled from south of the I-10 for a house north of it when closer tract sales exist.
