Single-story inventory is the tightest segment of the Porter Ranch market. Roughly 12-18% of 91326 single-family homes are true single-story, and they sell faster and at a premium to comparable two-story floor plans. I'm Brian Cooper, a Porter Ranch REALTOR with eXp Realty. If you're downsizing into a home you can age in place in, this guide covers which tracts have single-story product, what to expect on price, and the floor plan features that matter most.
Why Single-Story Inventory Is Tight
Porter Ranch was master-planned during eras that favored two-story product. Toll Brothers' Renaissance, Westcliffe Skyline, and Hillcrest collections are nearly all two-story or two-plus-loft. Builders maximize square footage per lot, and hillside tracts work better with two-story footprints because they sit lighter on the pad.
The single-story homes that do exist concentrate in Pacific Enterprises tracts from the 1990s (around Tampa, Sesnon, and Devonshire west of Mason), select KB Home plans from the early 2000s, and the Toll Brothers Bella Vista community where a few one-level plans were offered.
Which Tracts to Search
If true single-story is non-negotiable, focus your search on Pacific Enterprises tracts north of Rinaldi (1,800-2,400 sqft, often on 7,500-9,500 sqft lots), KB Home single-story plans in the Aliso Canyon area (2,100-2,800 sqft, 6,500-8,500 sqft lots), and resale Bella Vista one-level plans (2,400-3,200 sqft).
Porter Ranch Estates has a small number of one-story homes from the original 1980s build phase, but most have been added onto. Confirm in the appraisal that any second-floor addition was permitted before you write your offer.
| Source | Typical SqFt | Lot Size | Price Range (May 2026) |
|---|---|---|---|
| Pacific Enterprises 1990s | 1,800-2,400 | 7,500-9,500 | $1.05M-$1.35M |
| KB Home early 2000s | 2,100-2,800 | 6,500-8,500 | $1.15M-$1.45M |
| Toll Brothers Bella Vista | 2,400-3,200 | 6,500-9,000 | $1.55M-$1.95M |
| Porter Ranch Estates original | 1,700-2,300 | 8,500-12,000 | $1.10M-$1.45M |
The Single-Story Premium
Across May 2026 comps, true single-story homes have closed at a 4-8% premium over comparable two-story homes in the same tract, same square footage, same lot. The premium widens for buyers over 55 and narrows for first-move-up buyers who prefer the bedroom separation a two-story floor plan offers.
Days on market for single-story listings runs 12-18 days versus 23 for the broader 91326 market. Multiple offers are more common, especially at $1.1M-$1.4M.
Aging-in-Place Features to Look For
Step-down living rooms, sunken family rooms, and large grade changes between rooms are common in 1980s and 1990s Porter Ranch product. They're fixable but expensive. Walk every threshold during your showing.
Doorway widths in older tracts often run 30 inches, below the 32-36 inch ADA-recommended minimum. Master bathroom layouts in Pacific Enterprises tracts often have a step into the shower; KB Home plans more frequently have curbless shower-ready layouts.
- Zero or low thresholds between rooms
- Doorways at 32 inches or wider
- Master bath on the main level (true single-story is rare with a bonus loft)
- Curbless or convertible shower in the master
- Laundry on the main level (verify, some plans put it in the garage)
- Hallway widths of 36 inches or more
- Reachable storage in the kitchen
Garage and Driveway Considerations
Most Porter Ranch single-story homes have two-car or three-car attached garages. Hillside tracts often have steep driveways — verify the grade if you anticipate mobility changes or want safer ingress in wet weather.
Pacific Enterprises and KB Home single-story plans more commonly offer side-entry garages that allow a flatter driveway approach. Renaissance and Westcliffe Skyline tracts (mostly two-story) often have steeper short driveways because lot pads were graded for two-story massing.
How to Win in a Tight Segment
Set MLS alerts for 91326, single-family, 1 story, and adjust the price band 5-10% above your target — listings get bid up. Be ready to write an offer within 48 hours of first showing. Pre-underwritten financing or proof of cash is a meaningful advantage in this segment.
If you can be flexible on cosmetic condition, broaden your search to include homes with dated kitchens or bathrooms. Renovation in a single-story shell is far cheaper than waiting six months for the next clean listing.
