What does a green-building project cost in Porter Ranch in 2026?

Green-building scopes in Porter Ranch (91326) run $9K-$132K in 2026 at the Valley-premium tier (+10% versus LA baseline). A 10kW solar PV array lands $22K-$30K installed, a Tesla Powerwall 3 battery adds around $18K, and a heat-pump HVAC swap runs $3,500-$25,000 before LADWP rebates. Baily scopes the exact mix once it knows your current panel size and roof orientation.

Is the federal 30% solar tax credit still available in Porter Ranch?

No. The federal 30% residential solar ITC under IRS Section 25D expired December 31, 2025 under the OBBBA legislation, and most contractor websites still advertising it are out of date. For 2026 Porter Ranch projects, LADWP rebates are now the primary incentive — up to $2,500 per ton on heat pump HVAC and up to $2,500 per unit on heat pump water heaters, both active as of November 1, 2025.

Does Title 24 require solar on a new ADU in Porter Ranch?

Yes. California's Title 24 2025 solar mandate applies to all new single-family homes, low-rise multifamily, and ADUs in Porter Ranch (91326) — your new ADU must include solar PV sized to cover its projected annual load. Orientation and shading exemptions exist for deeply shaded parcels, but they require an engineer's shading analysis filed with the permit. Re-roofs over 2,000 sqft also trigger solar-ready conduit and panel-space requirements even if you defer the panels.

How does LADWP net metering change solar payback in Porter Ranch?

LADWP still runs true net energy metering with retail-rate export credits of roughly $0.22-$0.37 per kWh, which is why solar-only payback in Porter Ranch lands near 7 years even without a battery. LADWP also pays up to $350 per year per enrolled Powerwall through its Virtual Power Plant program. That stacks on top of the Title 24 compliance value, and Baily factors both into the scoped 10kW number.

Do I have to upgrade my electrical panel for heat pumps and solar in Porter Ranch?

Most Porter Ranch homes sit on 100A or 125A service, which is tight once you stack solar + battery + heat pump HVAC + heat pump water heater + EV charger. A 200A upgrade runs $2,000-$7,500 with a LADBS Van Nuys branch permit. The alternative is a SPAN smart panel at $7,250-$8,250 installed — it load-manages the existing service so you avoid the trenching and utility upgrade. Baily models both paths for your 91326 address.

What overlay reviews affect green-building projects in Porter Ranch?

In Porter Ranch, Very High Fire Hazard Severity Zone triggers WUI Chapter 7A ember-resistant vents and Class A roofing on any solar re-roof; hillside-ordinance grading review can add 3-8 weeks when a subpanel trench crosses a slope-constrained area. Separately, LA City Council's all-electric mandate for new construction drives heat pump and induction specs, which removes gas-line permit scope on qualifying rebuilds. Baily flags which of these actually affect your scope before a contractor call.

Can I still install gas appliances during a rebuild in Porter Ranch?

LA City Council unanimously approved an all-electric mandate for new construction, and in Porter Ranch's Very High Fire Hazard Severity Zone, eliminating gas also removes a meaningful ignition-source risk in an ember event. Heat pump HVAC ($3,500-$25,000), heat pump water heater ($1,200-$5,500), and induction cooking cover the full load. LADWP rebates offset roughly 20-30% of the electrification cost on qualifying projects.

What's a realistic whole-home electrification scope for a Porter Ranch house?

A full electrification project in Porter Ranch — solar PV, battery, heat pump HVAC, heat pump water heater, induction range, EV charger, Title 24 insulation + windows — runs $53K-$88K before incentives. LADWP rebates typically recover 15-20%, so the net lands roughly $44K-$79K. Expect 4-8 weeks on site with a LADBS Van Nuys branch permit, plus 2-4 weeks of design and utility coordination upstream.

“A string of bright beads of sunlight, breaking through the valleys along the moon’s rim.”

— Francis Baily, 1836

Origin

Who is Baily?

Baily is named after Francis Baily — an English stockbroker who retired at 51, became an astronomer, and in 1836 described something on the edge of a solar eclipse that nobody had properly articulated before: a string of bright beads of sunlight breaking through the valleys along the moon’s rim.

He wasn’t the first to see them. Edmond Halley saw them in 1715 and barely noticed. Baily’s contribution was clarity — describing exactly what was happening, in plain language, so vividly that the whole field of astronomy paid attention. The phenomenon is still called Baily’s beads.

That’s what we wanted our AI to do. Every inbound call and text has signal in it — a homeowner’s real question, a timeline, a budget, a hesitation that means “yes but.” Baily listens to every one, 24/7, and finds the beads of light.

Baily was a businessman before he was a scientist. That’s our vibe too.
