What does a garage conversion cost in Shadow Hills in 2026?

Shadow Hills garage ADU conversion runs $92K-$224K in 2026 — the LA median on the $90K-$220K LA baseline for a 400-600 sqft detached or attached conversion. JADU (under 500 sqft, shared kitchen): $82K-$153K. Non-habitable home office or gym: $5K-$46K since Title 24 2025 and CBC 302 separation don't trigger. Very High Fire Hazard Severity Zone overlay in 91040 adds $8K-$20K for Chapter 7A assemblies — ember-resistant vents, tempered glazing, Class A roof.

Can I sell my Shadow Hills garage ADU separately under AB 1033?

AB 1033 (effective 2024) allows cities to authorize separate condominium sale of ADUs. Shadow Hills falls under LADBS Van Nuys branch — confirm local adoption before banking on separate sale, since each jurisdiction opts in individually. Where adopted, a garage ADU can be sold as a standalone condo from the primary, often unlocking $250K-$600K in resale value that the rental-only pathway leaves untapped.

Is a Shadow Hills garage conversion by-right under state ADU law?

Gov Code §65852.2 gives Shadow Hills garage conversions by-right ministerial approval when the ADU stays under 750 sqft and inside the existing garage footprint. LADBS runs a 60-day ministerial clock, no discretionary design review, no setback variance. SB 9 lot splits layer on top — a Shadow Hills homeowner can split the lot then add an ADU to each new parcel, effectively doubling density by-right.

Do I have to replace parking when I convert my Shadow Hills garage?

No. California Gov Code §65852.2 waives replacement parking for any garage-to-ADU conversion statewide — Shadow Hills included. The rule also waives parking for new ADUs within 0.5 miles of a major transit stop or up to one ADU per lot regardless of transit. For 91040 homeowners, that usually means the existing driveway stays driveway and you don't lose square footage carving out a new space.

Where does a Shadow Hills garage conversion get permitted?

LADBS Van Nuys branch processes Shadow Hills garage conversions on the 60-day ministerial ADU window under Gov Code §65852.2. Build runs 2-3 months after permit issue. Plan set: architectural, PE-stamped structural, Title 24 2025 CF1R, MEP. AB 1332 pre-approved plans collapse review to 30 days. Permit fees $4K-$10K on valuation; SB 543 eliminates impact fees under 750 sqft effective January 2026.

What structural work does a Shadow Hills garage conversion require?

Shadow Hills hillside garages often need a new perimeter footing or grade beam before conversion — the original slab was never designed for habitable live load. Shear walls per ASCE 7 SDC D (LA seismic category) add $8K-$20K for plywood sheathing, hold-downs, and Simpson Strong-Tie connectors. 1-hour fire-rated separation per CBC Section 302 between the new ADU and the main residence is non-negotiable — 5/8" Type X drywall assembly.

What does Title 24 2025 require for a Shadow Hills garage ADU?

Title 24 2025 makes heat-pump HVAC the prescriptive baseline for Shadow Hills garage ADUs — no gas furnace without a performance-path tradeoff. Heat-pump water heater is also prescriptive. The CF1R energy compliance form gets stamped by a CEA consultant. ADUs under 1,000 sqft stay exempt from the new-construction PV solar mandate per 2022 cycle clarification. Budget $6K-$14K for full code compliance.

How does Shadow Hills shape garage-conversion strategy?

Shadow Hills sits in ZIP 91040, 20,000 sqft typical lot, permitted through LADBS Van Nuys branch. LA median ADU demand — rental comps land $2,200-$3,000/mo, resale adds $180K-$280K to parcel value. For a Shadow Hills garage conversion, hillside setbacks and slope-band constraints shape the garage envelope from day one. Pre-approved plans under AB 1332 and the CalHFA $40K forgivable grant both stack on top of the state ADU pathway.

“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.
