ADU in Panorama City, CA
Junior ADU & Interior Conversion in Panorama City typically runs $85,000-$165,000 all-in, drawings through final inspection, while ADU Site Prep & Utilities adds $15,000-$45,000 depending on whether we’re upgrading a 1940s electrical panel or trenching new sewer laterals through the valley’s hardpan clay. We’re Ellery ADU Studio, and we’ve found that Panorama City’s concentration of Kaiser-built postwar ranch homes - nearly identical 900-1,100 square foot houses on 6,000-7,500 square foot lots - creates one of the most predictable ADU environments in Los Angeles, provided you understand what’s hiding in those walls.

Why Panorama City Homes Are Different
Panorama City sits on the flat San Fernando Valley floor where summer temperatures routinely hit 105°F, ten to fifteen degrees hotter than coastal LA. Every ADU here needs dedicated cooling, and Title 24 energy calculations use climate zone 9, not the milder coastal zones.
The housing stock is remarkably uniform: Kaiser Community Homes built hundreds of minimal-traditional wood-frame ranches between 1947 and 1955, each with a detached single-car garage sized for postwar vehicles. These garages are often too narrow for modern cars and have been informally repurposed for decades. Original 100-amp panels, galvanized supply lines, and cast-iron drains are standard issue and almost always require full upgrades when an ADU adds electrical load or a second plumbing fixture group.
Perhaps most distinctive is what we find inside those walls. Contractors pulling permits on what looks like a simple garage conversion routinely discover unpermitted electrical subpanels, rough plumbing stubbed to makeshift bathrooms, and non-code framing layered in over thirty to forty years. That means a full as-built drawing and structural assessment before LA City will accept the permit application - a reality that barely exists in wealthier Valley cities.
Our Main Panorama City Services
Panorama City homeowners call us most often for these three services:
ADU Design & Permitting in Panorama City
We produce the permit set as the core product, not an afterthought. In Panorama City, that means as-built documentation of unpermitted conditions before LA City submission, plus Title 24 energy modeling for zone 9 valley-floor conditions. ADU Design & Permitting in Panorama City covers everything from zoning verification to final plan-check approval.
Garage Conversion ADU in Panorama City
The Kaiser tract garages here are conversion candidates, but only after we address the informal electrical and plumbing that accumulated across generations. We handle the structural assessment, the permit set, and the build under one contract at one written price. Garage Conversion ADU in Panorama City starts with what we find, not what we assume.
New Detached ADU in Panorama City
With 6,000-7,500 square foot lots and generous LA City ADU setbacks, Panorama City’s lot-to-house ratio makes detached units mathematically ideal. We specify and coordinate prefab systems from Cover, Dvele, and Mighty Buildings within the same single contract. New Detached ADU in Panorama City includes full site prep and utility tie-ins.

Junior ADU & Interior Conversion in Panorama City
Junior ADU & Interior Conversion in Panorama City solves a problem specific to this neighborhood: decades of informal multi-generational living arrangements that need legalization under LA’s ADU amnesty pathway. The Kaiser-built stock - small ranches with underutilized basements, attached rooms, and garage-adjacent spaces - offers more conversion volume than new construction potential. Junior ADU & Interior Conversion is our most called-for service here because so many families already have the space, just not the permits.
Room-to-ADU Conversion
Signs you need it
An attached bedroom or den already has a separate entrance and informal kitchenette, but no Certificate of Occupancy.
What it costs in Panorama City
Room-to-ADU conversions in Panorama City typically run $85,000-$125,000 all-in, including the as-built survey, permit set, and bringing original 1940s systems up to current LA City code.
How we do it
We document existing conditions with photo record, produce as-built drawings for LA City, upgrade electrical and plumbing to support the new fixture group, and build to the permitted drawings under our single contract.
Interior JADU
Signs you need it
You have an existing bedroom or living area within the main house that could become a self-contained unit with its own entrance and efficiency kitchen.
What it costs in Panorama City
Interior JADUs in Panorama City typically run $75,000-$115,000 all-in, including fire separation, sound attenuation between units, and dedicated utility metering where required.
How we do it
We verify the owner-occupancy requirement, design the separation and egress per LA City JADU standards, produce the full permit set, and construct with documented photo record at each visit.

Can a Junior ADU share utilities with the main house?
Yes, LA City allows JADUs to share electrical and water services with the primary residence, though we often recommend sub-metering for rental clarity. Call (747) 294-4817 for an exact quote - estimates are free.
How long does a room-to-ADU conversion take in Panorama City?
From permit submission to final inspection, typically 6-9 months in Panorama City, with 2-3 months for the as-built documentation and plan check given LA City’s current ADU queue. Call (747) 294-4817 for an exact quote - estimates are free.
ADU Site Prep & Utilities in Panorama City
ADU Site Prep & Utilities in Panorama City almost always means upgrading systems that were adequate for a 900-square-foot 1948 ranch but not for a modern ADU with full kitchen, laundry, and cooling load. The valley-floor hardpan and summer heat extremes compound the challenge: trenching is slow, and every new unit needs dedicated cooling sized for 105°F peaks. ADU Site Prep & Utilities is where single-contract design-build matters most, because the electrical panel upgrade, sewer lateral, and foundation work must be coordinated before the ADU build starts.
Electrical Panel Upgrade
Signs you need it
Your main panel is 100 amps with a Federal Pacific or Zinsco breaker, or the ADU load calculation exceeds available capacity.
What it costs in Panorama City
Electrical panel upgrades in Panorama City typically run $4,500-$8,500 for 200-amp service, including LADWP coordination and permit.
How we do it
We run load calculations for the existing house plus ADU, submit the LADWP service request, install the new panel with documented photo record, and schedule city inspection before any downstream work proceeds.
Plumbing Lateral
Signs you need it
The existing sewer line is 3-inch cast iron with visible root intrusion or belly, or the ADU adds a second fixture group beyond the original design.
What it costs in Panorama City
Plumbing lateral replacement in Panorama City typically runs $8,000-$18,000, including trenching through valley hardpan, city sewer connection permit, and inspection.
How we do it
We video-inspect the existing line, produce the replacement plan for LA City, trench with minimal disruption to established landscaping, and document with photo record at pre-cover inspection.
What ADU Site Prep & Utilities Costs in Panorama City
| Item | Typical range in Panorama City |
|---|---|
| Electrical Panel Upgrade | $4,500 - $8,500 |
| Plumbing Lateral | $8,000 - $18,000 |
| Foundation & Grading | $12,000 - $28,000 |
Does LADWP require a separate meter for an ADU?
Detached ADUs require separate electric meters in most cases; JADUs and some conversions can share service with sub-metering. Call (747) 294-4817 for an exact quote - estimates are free.
How deep do you trench for sewer laterals in Panorama City?
Typical burial depth is 18-24 inches for sewer and 24-30 inches for water, though valley hardpan can require pneumatic tools that add labor. Call (747) 294-4817 for an exact quote - estimates are free.

FAQs About ADU in Panorama City
LA City Department of Building and Safety currently processes ADU permits in 3-5 months for complete applications, with Panorama City projects falling under the Van Nuys plan check district. Incomplete as-built documentation of unpermitted conditions is the most common delay.
Most Panorama City neighborhoods lack HOAs - the area was built as open tract housing in the 1940s and 1950s. Where covenants exist, state law generally overrides ADU prohibitions, though design review requirements may still apply.
We pull all permits as part of our single-contract scope, per Haven Standard Clause 3. The homeowner receives copies of every permit, inspection record, and final Certificate of Occupancy, but we handle submission and plan-check correspondence directly with LA City.
