Fast, Reliable Garage Conversion ADU Across Encino
A garage conversion ADU in Encino typically runs $185,000-$275,000 all-in, drawings through final inspection, depending on whether the garage is attached or detached and whether the parcel falls south of Ventura Blvd into the fire-hazard zone. Permitting takes 4-7 months through LADBS. The exact number on your project gets locked in writing before work starts, per Haven Standard Clause 1.
We’ve been designing and building garage conversions in Encino since the studio opened in 2015. Nadia Ellery runs the practice under one contract, one written price. No designer blaming the builder when a wall lands three inches off the permit set. If you’re considering converting a 1960s two-car garage into a JADU or full ADU, call (971) 497-2402 and we’ll walk the lot with you.
Why Ellery ADU Studio Is Encino’s Preferred Garage Conversion ADU Company
Encino isn’t one permitting environment. It’s two. North of Ventura Blvd, you’re on flat-lot ranch ground with straightforward LADBS review. South of Ventura, toward Mulholland, your parcel sits inside the Very High Fire Hazard Severity Zone. That single fact changes your framing requirements, your eave vents, your roofing material, and your inspection sequence. We check the fire-hazard tier before we quote anything on this page, because a two-block shift in address changes the entire scope.
We’ve designed, permitted, and built 900+ ADUs since 2015, every single one with a written price before work started. Encino homeowners hire us because the permit set is the product, not an afterthought. The drawings, the Title 24 calculations, the fire-hardening details, the foundation spec, the mini-split sizing. All documented. All yours.
Our crews working in Encino are background-checked and uniformed. Schedules are coordinated from our Los Angeles office, and crews serve Encino locally. When you call (971) 497-2402, a live person answers. That’s not a marketing line. Try it.
Our Garage Conversion ADU Services in Encino
Detached Garage Conversion
Detached garage conversions are the most common ADU project we handle in Encino, and the lot geometry works in your favor. Many of these 1950s and 1960s garages sit at the rear of 10,000 to 20,000 sq ft parcels, which means the conversion rarely fights the rear setback the way it does on tighter Sherman Oaks or Van Nuys lots. The question is whether your detached garage triggers fire-zone requirements. South of Ventura Blvd, LADBS will require ignition-resistant eave vents, ember-resistant window units, and Class A roofing, even if you’re not touching the roof structure. We scope those retrofits before quoting so the price you see is the price you sign.
Attached Garage Conversion
An attached garage conversion on an Encino ranch home usually means converting the original garage bay into a one-bedroom unit with a shared wall against the main house. The slab is often 4 inches thick, which can work for a conversion if we keep the roof loads light and confirm the condition. But on attached conversions, we also look at what’s above the garage. Many Encino ranches have attic truss systems that were never designed for the insulation and HVAC loads a conditioned ADU requires. That’s where the price moves. We’d rather tell you now than discover it mid-build.
Garage JADU
A Junior ADU from an existing garage conversion in Encino is the most efficient way to add a rental or in-law unit under 500 sq ft. LADBS allows a JADU within the footprint of an existing single-family home, including an attached garage conversion. The bedroom count, kitchenette spec, and separate entrance become the permitting variables. On Encino’s deeper lots, we often see a JADU permitted alongside a new detached ADU at the same time, which means your utility runs, sewer tie-in, and grading plan need to be designed as one scope, not two.
Garage Partition & Bathroom Add
Sometimes the garage doesn’t need to become a full separate unit. A garage partition and bathroom add in Encino splits the existing garage into a living or work space with a new three-quarter bath. On older ranch homes, the sewer lateral is the wildcard. Many 1960s Encino homes still have original clay sewer pipe, and tying a new bathroom into it may require a partial lateral replacement under the slab. That’s a line item we identify during the site walk, not during construction.

Trusted Brands We Service in Encino
For Encino homeowners who want a prefab or modular garage conversion rather than a stick-built job, we specify and coordinate systems from Cover, Dvele, and Boxabl within the same single contract. The prefab panel or module gets ordered against the permit set we file, so there’s no finger-pointing between the factory and the jobsite. Encino deliveries require flatbed access and a crane staging plan if you’re on a hillside parcel south of Ventura, and we map that access route before we commit to a prefab system.
Common Garage Conversion ADU Problems We See in Encino Homes
- Fire-hazard tier not checked before quoting. A 1962 ranch on a flat street north of Ventura Blvd and a 1962 ranch two blocks south on a Mulholland-area slope have completely different LADBS requirements. Out-of-area builders who miss this get flagged mid-review at the Reseda office, and the owner eats the change order. We check the tier on day one.
- Undersized HVAC for 110-degree days. Encino’s basin location records some of the highest summer temperatures in the LA metro, regularly hitting 105 to 112 degrees with almost no coastal marine influence. A mini-split sized for a coastal unit will fail Title 24 and leave tenants sweltering. Our Encino conversions get higher-capacity condensers and high-R wall assemblies sized for actual Valley heat loads.
- Clay sewer laterals failing under new bathroom loads. Original 1960s clay pipe doesn’t love new flow patterns. We inspect the lateral before finalizing the scope on any garage partition with a bathroom add, because replacing a collapsed lateral under the rear yard is a five-figure line item you should know about before signing.
- Assuming a flat-lot permit when the parcel slopes. Even a modest grade change on an Encino hillside parcel can trigger a grading review, even if you’re not adding square footage. We’ve seen a 6-inch foundation raise flag a full drainage plan at LADBS. We scope it upfront.

We write all of this into a line-item scope before you sign anything. The price is the price. No door-side upsells, per Haven Standard Clause 5.

FAQs - Garage Conversion ADU in Encino
Yes, if your parcel sits in the Very High Fire Hazard Severity Zone south of Ventura Blvd, LADBS requires Class A roofing and ember-resistant venting even when you’re only converting an existing garage, not rebuilding it. The existing roof assembly gets evaluated as part of the permit review. If it doesn’t meet the fire-hazard tier, the conversion scope expands. We flag this before quoting so it’s not a surprise at the Reseda counter. Call (971) 497-2402 for the exact requirements on your address.
Usually yes. The 4-inch slabs common under 1960s Encino garages can support a conversion if the slab is in good condition and we’re not adding significant roof loads. The exception is when termite damage or soil movement has cracked the slab beyond what LADBS will accept without repair. We excavate a test section during the site walk and document what we find. That photo record is yours, per Haven Standard Clause 4.
It drives up the required mini-split capacity and insulation values. Encino regularly hits 105 to 112 degrees in summer heat events, so a garage conversion here needs a larger condenser and higher-R wall and ceiling assemblies than the identical unit in a coastal community. Title 24 energy compliance in this climate zone doesn’t allow undersized equipment. We size the HVAC from the permit set, not a rule of thumb, and the written quote reflects the actual load calculation.
Yes. Many Encino parcels are 10,000 to 20,000 sq ft, large enough under LA City’s multi-ADU rules to permit a garage conversion, a new detached ADU, and a Junior ADU simultaneously. The advantage of doing them together is one grading plan, one drainage design, one sewer tie-in, and one mobilized crew. The permit set for a joint scope is more complex, but it eliminates the re-permitting costs of doing them sequentially. We’ll tell you if your lot supports it during the first site walk.
Potentially, yes. Any foundation work on an Encino hillside parcel can trigger a grading review at LADBS, even if the conversion stays within the existing garage footprint. The issue is usually drainage and soil stability, not square footage. We check the parcel’s grading status before we quote, so the review fee and any required drainage plan are in the written price, not added later.
