Orange County

  • Tustin Primary

    Kemlux is based around Tustin, from the older ranch homes near Old Town to the newer construction around Tustin Legacy and Tustin Ranch.

  • Orange Primary

    From Old Towne Orange, where a remodel often has to work around a historic-district review, to the newer tracts near Santiago Hills, Orange is the other city Kemlux is built around.

  • Santa Ana

    A regular service area, with everything from post-war single-story homes to larger properties near Floral Park.

  • Irvine

    Additions, remodels and ADUs across Irvine’s villages, where HOA design review is often part of the permit timeline.

  • Villa Park

    Larger-lot, older-stock homes are common here, which usually means more structural and systems work bundled into a single remodel.

  • North Tustin

    An unincorporated community bordering Tustin, with a mix of ranch homes and larger custom properties on bigger lots.

  • Anaheim Hills

    Hillside lots and split-level layouts here often shape what an addition or ADU can do before design even starts.

  • Yorba Linda

    Larger single-family homes across Yorba Linda, from single-room remodels to full additions.

  • Costa Mesa

    A mix of older single-story homes near the Eastside and newer construction further west, with remodels and additions the most common calls.

  • Garden Grove

    Mostly post-war single-story homes on larger lots, which often leaves room for an ADU or addition without a variance.

  • Fountain Valley

    A regular service area of mostly single-family tract homes built from the 1960s through the 1970s.

  • Placentia

    Single-family neighborhoods throughout Placentia, from smaller ranch homes to larger custom lots.

Los Angeles County

  • Norwalk

    Just across the county line, with mostly post-war single-story homes where a remodel or addition is the common project.

  • Lakewood

    One of the country’s original large-scale planned suburbs, with single-story tract homes that are frequent candidates for a remodel or ADU.

  • Bellflower

    Post-war single-family neighborhoods throughout Bellflower, with additions, remodels, and ADUs the most common requests.

  • Long Beach

    From older bungalow neighborhoods like Bixby Knolls and California Heights to newer construction elsewhere in the city, Long Beach covers a wide range of remodel and addition work.

  • Cerritos

    Newer single-family construction throughout Cerritos, where remodels tend to focus on updated finishes and layouts.

  • La Mirada

    Suburban single-family tract homes across La Mirada, close enough to the county line to be a regular service area.
