ADU Remodeling in Westchester

Your Trusted Local ADU Partner

Whether you picture a detached backyard cottage for family or a rental unit for the LMU and LAX crowd, KN Remodeling is here to bring your ADU vision to life in Westchester.

Westchester is a Westside Los Angeles neighborhood built around Loyola Marymount University, Otis College of Art and Design, and LAX, with the wider Kentwood section known for its larger mid-century lots. That mix of steady university and airport-area demand, plus proximity to the growing Playa Vista tech corridor, makes an ADU here a strong income property, whether you are renting to students, staff, or young professionals. We understand City of Los Angeles zoning for this part of the Westside and design ADUs that fit comfortably with Westchester's mid-century architecture.

Frequently Asked Questions

Pricing depends on the square footage, whether you are building a detached backyard cottage or converting an existing garage, and the interior finishes you choose. As a general guide for the Los Angeles area:

  • Garage conversion or Junior ADU (JADU): roughly $90,000 to $150,000
  • Detached custom ADU (500 to 800 sq ft): roughly $180,000 to $260,000
  • Larger detached luxury ADU (800 to 1,200+ sq ft): $280,000 to $350,000+

Site prep for hillside properties, trenching long utility lines, or foundation upgrades can influence final costs. We provide a written, itemized estimate after your free in-home consultation so there are no vague allowances or surprise line items later.

Most detached ADU construction takes three to five months of active on-site work. Garage conversions can often be completed slightly faster, typically within two to four months.

  • Architectural design, structural engineering, title-24 energy calculations, and city permit approval take place before breaking ground and typically add two to four months
  • Custom elements like cabinetry, specialized roofing, and window packages require lead times, so we order them early
  • You receive a clear written schedule at the start and regular updates throughout the build

We streamline every phase to ensure your project moves forward smoothly without unnecessary delays.

Yes. KN Remodeling is a licensed Class B general contractor in California with more than 30 years of building experience. We carry full general liability and workers' compensation insurance on every project.

  • Structural framing, electrical panels, and plumbing connections are performed by licensed professionals and signed off by city inspectors

Yes. Westchester is part of the City of Los Angeles, so ADU permits are processed through the LADBS Development Services Center like the rest of the city. We handle the plan check, structural engineering, and inspection process from start to finish.

Westchester's mid-century character comes with a few local factors worth planning around:

  • Mid-Century Lots: the Kentwood section in particular tends to have larger, more flexible yards for a detached unit
  • Strong Rental Demand: proximity to LMU, Otis College, LAX, and the Playa Vista tech corridor supports steady tenant interest
  • Established Neighborhood Character: many homes here are mid-century in style, and we design ADUs to complement that look
  • Utility Access: older homes sometimes need utility upgrades to support a fully independent second unit

We evaluate all of these site-specific conditions during your free initial consultation.
