About this home

Tired of cookie-cutter homes that all look the same? This one breaks the mold. Welcome to your tri-level Porter Ranch retreat — a 4-bedroom, 2.5-bath home with flexibility built right in. Need a separate space for in-laws, guests, or a quiet home office? The lower level has its own entrance, bedroom, bathroom, and family room — no stairs required. Step into a sleek, remodeled kitchen that blends form and function — featuring quartz countertops, custom cabinetry, and a clean, modern design that makes both everyday meals and entertaining a joy. The bathrooms have also been stylishly updated, offering a fresh, contemporary feel throughout. The home has been thoughtfully upgraded with the big-ticket items already done for you: newer roof, updated electrical panel and gas meter, tankless water heater, new A/C, and solar panels installed just 3 years ago. You’ll also enjoy a whole-house water purification system and a variable-speed pool pump — because yes, there’s a pool. And with average electric bills around $50/month, you’ll stay cool without sweating the cost with an OWNER PAID SOLAR SYTEM(NOT LEASED). Located in one of Porter Ranch’s most sought-after pockets, you’re zoned for award-winning schools like Castlebay Lane Elementary, Frost Middle School, and Granada Hills Charter and close to top private options including Chaminade and Sierra Canyon. Just minutes from shopping, hiking trails, parks and the Vineyards at Porter Ranch, plus easy access to UCLA Health, Kaiser, dining, and freeways and more. This isn’t just a house — it’s a setup that works for how you actually live today.
