ADU in Studio City, CA
Junior ADU and interior conversions in Studio City typically start at $85,000 and can reach $175,000 depending on whether you’re working with a 1950s ranch foundation or a hillside property with fire-hardening requirements. We’re Ellery ADU Studio, and we’ve found that Studio City’s split personality - flatland ranch lots south of Ventura versus hillside parcels toward Mulholland - makes every interior conversion a unique permit puzzle. Call (424) 325-4322 for a written price before any work starts.
Why Studio City Homes Are Different
Studio City straddles two ADU realities that rarely coexist in one neighborhood. South of Ventura Boulevard, the flatland grid holds 1940s-1960s California ranch homes on 6,500-12,000 square foot lots, often with detached single-car garages and original 100-amp electrical panels. These are textbook conversion candidates, except most still run galvanized or cast-iron supply lines that LADBS will flag before any permit issues.
North toward Mulholland, hillside parcels sit in the Very High Fire Hazard Severity Zone. CAL FIRE defensible-space mandates and fire-resistant construction requirements add substantial cost. The Santa Ana winds channel through Fryman Canyon, intensifying scrutiny of every fire-hardening detail. Some hillside lots lack gravity-fed sewer laterals entirely, forcing engineered perc tests or uphill sewer extensions that flat-lot neighbors in the Carpenter School district never face. Summer temperatures above 110°F in unshaded rear yards make mechanical system sizing critical, not optional.
Our Main Studio City Services
Studio City homeowners call us most often for these three services, each with its own dedicated page and local pricing.
ADU Design & Permitting in Studio City
Our permit set is the core product, not an afterthought. In Studio City, that means navigating both LADBS’s standard review track for flatland conversions and the fire-department coordination required for hillside builds. We produce construction drawings, structural calcs, and Title 24 energy compliance as one package under a single written price. ADU Design & Permitting in Studio City covers the full process from feasibility study to issued permit.
Garage Conversion ADU in Studio City
The detached single-car garages common south of Ventura make ideal conversion candidates, but most need slab evaluation, panel upgrades, and sewer lateral replacement before LADBS will sign off. We handle the feasibility assessment, drawings, and build as one contract with one written price. Garage Conversion ADU in Studio City details flatland and hillside garage-specific requirements.
New Detached ADU in Studio City
Flatland lots with alley access or wide side yards can accommodate new detached units under LA’s permissive ADU ordinance, while hillside builds demand retaining-wall engineering and fire-resistant exterior assemblies. We coordinate prefab systems from Abodu, Cover, and Dvele within the same single contract. New Detached ADU in Studio City explains site constraints and modular options.

Junior ADU & Interior Conversion in Studio City
Junior ADU and interior conversions in Studio City solve a specific problem: homeowners who need rental income or family housing but lack the lot space or budget for a detached unit. The 1940s-1960s housing stock south of Ventura offers generous floor plans and separate entrances, while hillside homes often have underutilized lower levels with separate access. We handle Junior ADU & Interior Conversion as a single contract from measured drawings through final inspection, with every step documented.

We measure existing conditions, produce a permit set with Title 24 energy compliance, upgrade the electrical panel if needed, rough in kitchen and bath, install fire-rated separation, and pass final inspection with a documented photo record at each visit.

Your hillside or split-level home has a walk-out basement with separate entry, low ceilings, and no current legal occupancy status.
What it costs in Studio City
Basement ADU conversions in Studio City range $110,000-$175,000 depending on excavation for headroom, moisture mitigation, and whether the sewer lateral needs pumping to grade.
How we do it
We assess ceiling height and egress window requirements, design moisture barriers and mechanical ventilation, produce structural drawings for any underpinning, and coordinate LADBS and fire-department sign-off for below-grade occupancy.

Does a Junior ADU need its own meter in Studio City?
No, a Junior ADU shares utilities with the primary residence by definition, though we often recommend a sub-meter for rental fairness and LADBS compliance on electrical load calculations. Call (424) 325-4322 for a written quote on your specific layout.
Can I convert any room in a Studio City hillside home?
Not every room qualifies; hillside properties need legal egress, adequate ceiling height, and fire-rated separation that meets CAL FIRE standards for the Very High Fire Hazard Severity Zone. We assess feasibility before any design work begins.
ADU Site Prep & Utilities in Studio City
ADU site prep and utilities in Studio City address the hidden conditions that kill projects after permits are pulled: corroded galvanized lines, 100-amp panels that can’t handle a second kitchen, and hillside lots where sewer laterals don’t exist. We handle ADU Site Prep & Utilities as a defined scope with a written price, so your conversion or new build isn’t delayed by surprises.
Electrical Panel Upgrade
Signs you need it
Your 1950s ranch still has the original 100-amp panel, or your main breaker trips when the AC and dryer run together.

How we do it

Plumbing Lateral
Signs you need it
Your pre-1970 home runs galvanized or cast-iron supply lines, or your hillside lot lacks a gravity-fed sewer connection to the city main.
What it costs in Studio City
Plumbing lateral replacement in Studio City runs $8,000-$18,000 for flatland properties and $15,000-$35,000 for hillside lots requiring engineered pump systems or uphill extensions.
