ADU in Encino, CA
Junior ADU and interior conversion in Encino typically runs $85,000-$165,000 all-in, while site prep and utilities add $18,000-$55,000 depending on whether we’re upgrading a 60-amp sub-panel or trenching new sewer laterals across a 15,000 sq ft lot. We’re Ellery ADU Studio, and we’ve handled Junior ADU & Interior Conversion projects here since before the 2020 state law changes made these builds standard.

Why Encino Homes Are Different
Encino’s post-WWII ranch stock sits on some of LA City’s largest residential lots - 12,000-20,000+ sq ft between Ventura Boulevard and the 101 - but the structures themselves carry original 60-amp electrical service and no gas stub-outs, making utility upgrades a near-universal first cost. Summer temperatures routinely hit triple digits, 15-20°F above coastal LA, so HVAC load calculations here run substantially higher than city norms; undersized mini-splits fail fast. Fall Santa Ana winds bring ember risk from the Santa Monica Mountains, which means fire-rated exterior finishes and ember-resistant vents matter beyond code compliance. Many detached garages measure 20×20 ft finished interior, triggering full Title 24 energy compliance at exactly 400 sq ft - a permit milestone that adds 3-5 weeks for unprepared projects.
Our Main Encino Services
Encino homeowners call us most often for these three core services.
ADU Design & Permitting in Encino
We produce the full permit set - structural, Title 24, drainage - as the core deliverable, not an afterthought. In Encino, that means addressing the 400 sq ft Title 24 trigger on garage conversions and documenting oversized-lot drainage for new detached units. Every set is submitted under our license with a written price locked before drafting begins. ADU Design & Permitting in Encino covers the full path from feasibility study to LADBS approval.
Garage Conversion ADU in Encino
Encino’s 1950s two-car garages are prime conversion candidates - 20×20 ft or larger, already roofed and slabbed - but the 60-amp panels and lack of gas lines mean electrical and plumbing rough-in drives the schedule. We handle the full conversion under one contract, including the permit set and the build. Garage Conversion ADU in Encino covers everything from slab moisture testing to final inspection.
New Detached ADU in Encino
Oversized Encino lots allow detached ADUs that denser Valley neighborhoods simply cannot fit - 800-1,200 sq ft units with proper setbacks and parking compliance. We design, permit, and build these as a single contract, including site prep and utility trenching. New Detached ADU in Encino covers the full process from feasibility to certificate of occupancy.

Before
AfterJunior ADU & Interior Conversion in Encino
Encino’s 1948-1975 ranch homes offer exceptional Junior ADU and interior conversion potential - existing floor plans with separate entrances, attached garages with direct house access, and room configurations that convert cleanly under JADU rules. The challenge is the electrical: original 60-amp service cannot handle added dwelling loads, and the summer heat demands properly sized HVAC from day one. We handle Junior ADU & Interior Conversion as a single contract, drawings through final inspection, with a written price before any work starts per Haven Standard Clause 1.
Room-to-ADU Conversion
Signs you need it
You have a ground-floor bedroom or den with exterior access, a separate entrance, and you’re willing to share utility meters with the main house under JADU rules.
What it costs in Encino
Room-to-ADU conversions in Encino typically run $85,000-$140,000 all-in, including the mandatory electrical panel upgrade from 60-amp service.
How we do it
We verify the existing space meets JADU square-footage limits, design the kitchenette and wet bar layout, produce the full permit set, upgrade electrical service, and build to final inspection with a documented photo record at every visit.
Above-Garage ADU
Signs you need it
Your detached garage has unused attic space or a structurally sound roof framing system that can support a second-floor dwelling unit with proper stair access.
What it costs in Encino
Above-garage ADUs in Encino typically run $120,000-$165,000 all-in, including structural reinforcement for the added floor load and full utility rough-in.
How we do it
We assess the existing framing for live-load capacity, design the stair and egress path, produce structural calcs and the permit set, reinforce as needed, and build the unit with fire-rated separation per code.
What Junior ADU & Interior Conversion Costs in Encino
| Item | Typical range in Encino |
|---|---|
| Room-to-ADU conversion | $85,000 - $140,000 |
| Above-garage ADU | $120,000 - $165,000 |
| Electrical panel upgrade (required) | $8,000 - $15,000 |
Can a Junior ADU have its own electric meter in Encino?
No - JADUs by state law must share utility meters with the primary residence, though we separate sub-panels so your tenant’s usage is trackable. Call (424) 523-8492 for an exact quote - estimates are free.
How long does a room-to-ADU conversion take in Encino?
Typically 4-6 months from permit submission to final inspection, assuming no LADBS backlog; the electrical upgrade and Title 24 compliance are the critical-path items. Call (424) 523-8492 for an exact quote - estimates are free.
ADU Site Prep & Utilities in Encino
Encino’s large lots and aging infrastructure make site prep and utilities a standalone project phase - trenching across 15,000 sq ft, upgrading 60-amp panels to 200-amp service, and extending gas lines where none existed. The summer heat and Santa Ana wind exposure also mean we spec fire-rated hardscape and ember-resistant venting as standard, not optional. We handle ADU Site Prep & Utilities under the same single contract as the build, with the same written-price guarantee.
Electrical Panel Upgrade
Signs you need it
Your existing panel is 60 amps, has no open breaker slots, or shows corrosion from decades of Valley heat cycling.
What it costs in Encino
Electrical panel upgrades in Encino typically run $8,000-$15,000, including the new 200-amp service, grounding, and LADBS inspection.
How we do it
We pull the LADBS permit, coordinate DWP service disconnect, install the new panel with proper grounding, and pass inspection before any ADU rough-in begins.
Plumbing Lateral
Signs you need it
Your ADU location is more than 30 feet from the main sewer line, or the existing lateral is original cast iron with visible corrosion or root intrusion.
What it costs in Encino
Plumbing lateral extensions in Encino typically run $12,000-$25,000 depending on trench length across large lots and any street-to-main work.
How we do it
We camera the existing line, design the new lateral path, trench with proper slope and bedding, install ABS or PVC to code, and test before backfill.
What ADU Site Prep & Utilities Costs in Encino
| Item | Typical range in Encino |
|---|---|
| Electrical panel upgrade | $8,000 - $15,000 |
| Plumbing lateral extension | $12,000 - $25,000 |
| Gas line extension | $5,000 - $15,000 |
Do I need to upgrade my electrical panel before ADU work starts?
Almost always yes in Encino - original 60-amp service cannot handle added dwelling loads, and LADBS will not issue an ADU permit without adequate service capacity. Call (424) 523-8492 for an exact quote - estimates are free.
Can site prep be done under the same contract as the ADU build?
Yes - that’s our standard model; site prep, utilities, and construction are one contract at one written price per Haven Standard Clause 1, so no contractor can blame a separate designer for scope gaps. Call (424) 523-8492 for an exact quote - estimates are free.

What Encino Customers Say
"The rental income has covered the payment since the second month. They were realistic about the numbers rather than optimistic."
- Odette N."They walked us through setbacks and utility capacity before we paid anything, and told us one of our two options was not going to get approved."
- Mireille T."The permit set and the build were one contract with one number. Our neighbours used two firms and spent a year watching them blame each other."
- Helena V.
