Lost Canyons, Simi Valley (93063)

We're Steve Hise and Tricia Garcia, and we've spent 10 years helping people buy and sell across Simi Valley and Ventura County. This page tracks what's planned at Lost Canyons, where things stand, and what to know if you're thinking about buying a new home there.

Where is Lost Canyons?

Lost Canyons is in the hills at the north end of Tapo Canyon Road, at 3301 Lost Canyons Drive. The site covers about 1,770 acres, including Dry Canyon and Tapo Canyon.

A short history

• 2001: Lost Canyons Golf Club opened as a public club with two 18-hole courses, the Shadow Course and the Sky Course, designed by Pete Dye and Fred Couples.
• 2006: A plan was proposed to build 364 homes on part of the site.
• 2016: The golf club closed for good.
• 2020: The Planning Commission gave final design approval for the first phase of 184 homes.
• 2026: A revised plan dropped the golf course and moved most of the homes north of Lost Canyons Drive.

What's planned now?

Here's the revised plan as reported in August 2026:

• 364 homes total, the same number approved before. 178 homes would move from south of Lost Canyons Drive to the former fairways on the north side.
• Much more open space. The building footprint would shrink from about 500 acres to under 300, and open space would rise to almost 90% of the site, up from about 43%. Most of the land south of Lost Canyons Drive, including Dry Canyon, would stay open.
• No golf course. The plan for a new golf course was dropped.
• Public trails. Old golf cart paths would become public walking trails, and a public trailhead is planned at Tapo Canyon Road and Lost Canyons Drive.
• Road work. Tapo Canyon Road would get bike lanes, a sidewalk, and a new traffic signal at Lost Canyons Drive.
• The builder. The land developer is Newport Pacific Land Co., and Toll Brothers is expected to build the homes.

Where do things stand?

On August 10, 2026, the City Council gave the revised plan unanimous initial approval, after a 4-0 Planning Commission recommendation on June 3. A final council vote was still pending at that time. Grading for roads and infrastructure has started under the earlier approval, and home construction is expected to begin next year if the revised plan gets final approval. Plans can still change, so we'll update this page as the city acts.

What will the homes be like?

The first phase, as approved in 2020, called for 184 single-family homes of about 3,000 to 4,000 square feet. Floor plans, prices, and HOA details for the revised plan haven't been released yet. When they are, we'll add them here.

Thinking about buying a new home at Lost Canyons?

• Bring your own agent on your first visit. Many builders only work with your agent if they're with you, or registered, the first time you visit the sales office. Builders often pay the buyer's agent, and we'll confirm how it works at Lost Canyons before your first visit.
• Get pre-approved early. New-home releases can move fast, and builders often want proof of financing before you reserve a lot.
• Plan the sale of your current home. New construction takes months. We line up the sale of your current home with the builder's closing date so you move once.
