Fast, Reliable ADU Builders Across Sherman Oaks
Building an ADU in Sherman Oaks means working with a contractor who actually understands what sits under these 1950s and 60s ranch homes. A detached ADU here typically runs $280,000 – $420,000, a garage conversion $160,000 – $240,000, and a JADU $90,000 – $140,000, but those numbers shift fast if the LADBS permit history turns up post-Northridge foundation work that was never properly recorded. We are ADU Builders who pull that history before we price, not after we open the walls. Call (254) 602-5618 to get a written estimate that accounts for what your lot actually holds.
Why Lodgewick ADU Builders Is Sherman Oaks’s Preferred ADU Builders Company
Sherman Oaks homeowners keep calling us because we put the painful parts of an ADU build on paper before they happen.

Our ADU Builders in Sherman Oaks reputation rests on the 365-Day Done Right Promise: if the work isn’t right, we come back and make it right, in writing, on every single project.
Every Lodgewick crew member is background-checked and uniformed. You know exactly who is on your property. The price is written before work starts. The arrival window is real. The job site gets cleaned daily, and the guarantee is delivered in writing before a single nail is driven. That’s the Kingswell Way, and it’s why homeowners who have been burned by a price that changed at the door call us instead.
JADU in Sherman Oaks
A JADU in Sherman Oaks is typically a junior accessory dwelling unit carved out of the existing footprint of your single-family home, capped at 500 square feet, most often built from a spare bedroom, den, or underused attached space. Sherman Oaks homeowners choose this route when they want rental income or a private space for aging parents without adding a whole new structure to the lot. A JADU here runs $90,000 – $140,000 depending on whether the space needs its own kitchenette, separate entrance, and bathroom, which LADBS requires for legal occupancy.
The LA City Layered Opportunity
The quiet advantage most Sherman Oaks homeowners don’t know they have: because this side of the hill sits inside City of Los Angeles, a standard R1 lot can support both a full detached ADU and a JADU at the same time. That means the bonus room conversion plus a new backyard unit, two rentable spaces, one tax parcel. Burbank and Glendale don’t allow that layered configuration under their own codes. We flag this in every consultation because it changes the entire project math.
When the Interior Needs Reconfiguring
Opening up an older Sherman Oaks interior for a JADU almost always triggers code upgrades. The existing wiring may be cloth-insulated. The bathroom may sit on a slab that drains incorrectly. LADBS will require the new unit to meet current electrical, egress, and ventilation standards, even if the adjacent rooms don’t. Russ Delmar builds those allowances into the written estimate so the price doesn’t creep after demo begins.
ADU Plans in Sherman Oaks
ADU Plans in Sherman Oaks are the full construction documents we submit to LADBS on your behalf, including site plans, structural drawings, Title 24 energy calculations, and the fire-safety details that apply to hillside parcels along the Mulholland corridor. Homeowners need us to handle ADU Plans when their architect’s drawings don’t account for the local permitting triggers, or when a prefab manufacturer’s stock plans need local adaptation. Plan-drawing and permit coordination for a Sherman Oaks ADU typically runs $8,000 – $18,000 depending on site complexity and fire-zone requirements.
Plans That Account for Northridge History
The permit history on a pre-1994 Sherman Oaks home often shows foundation repairs, shear-wall retrofits, or rebuilt garage framing filed after the quake. Those records live at LADBS, and any competent ADU plan must reconcile them with what’s actually on the ground today. We have seen repaired footings that never made it into the file, which means the structural drawings have to be verified against the physical foundation, not just the paperwork.
Plans for Prefab and Modular Builds
When a Sherman Oaks homeowner chooses a prefab or modular ADU, the factory provides the base plans, but LADBS still needs site-specific engineering for the foundation, anchoring, utility connections, and fire-rated assemblies if the lot sits in a Very High Fire Hazard Severity Zone. We adapt factory drawings from Abodu, Cover, Dvele, and others to meet Sherman Oaks and LA City requirements before submitting. That step prevents a rejected permit and a two-month delay.
Trusted Brands We Service in Sherman Oaks
We work with established prefab and materials brands that perform well on Sherman Oaks lots: Abodu for fast backyard units, Cover for precision-built modulars, James Hardie for fire-rated siding that satisfies Mulholland corridor requirements, and Dvele for high-performance envelope systems. Because we are local, we don’t wait on out-of-state shipments for common parts and materials. Our Sherman Oaks projects move on schedule because the supply chain and the crew are both rooted here on the Valley floor.
Common ADU Builders Problems We See in Sherman Oaks Homes
- Unreinforced 1960s garage slabs cracked from Northridge settling. These pours are typically 3.5 inches thick, uninsulated, and not engineered for habitable space. We budget for slab replacement or a raised floating-floor system before we quote, not after the concrete comes up.
- Post-quake foundation patches that never made it into the LADBS permit file. A homeowner may believe the garage is original, but a shear-wall retrofit or stem-wall repair from 1995 changes the structural picture. We pull the permit history upfront and reconcile it with the actual foundation.
- HVAC sized for coastal LA, not the Sherman Oaks summer. The Valley floor hits 100 – 108°F routinely, which is 15°F or more above the Westside. An undersized mini-split fails Title 24 and turns the ADU into an unlivable box by June.
- Contractors who never flag the JADU-plus-ADU option. On a standard R1 lot in Sherman Oaks, you can build both a detached ADU and a JADU. Missing that layered opportunity leaves rental income and square footage on the table, and we see out-of-area contractors skip it entirely.
Pricing for ADU Builders in Sherman Oaks, CA
Here are real ranges for this market. A detached ADU in Sherman Oaks typically lands between $280,000 and $420,000. A garage conversion runs $160,000 to $240,000. A JADU sits in the $90,000 to $140,000 range. A custom build with higher-end finishes on a hillside lot along Mulholland can push past $450,000 because of fire-rated assemblies and defensible-space work. The single biggest swing factor on older Sherman Oaks homes is what the permit history reveals: a cracked slab, an unpermitted patio roof over the proposed site, or a post-quake retrofit that changes the foundation plan. That’s why our written price includes inspection-first allowances and any surprise is priced and approved in writing before we touch it. Call (254) 602-5618 for a free estimate with real numbers.

FAQs About ADU Builders in Sherman Oaks
Because contractors who don’t pull LADBS permit history price the job off the surface only. A 1960s garage slab that looks fine may be 3.5 inches thick, uninsulated, and cracked from Northridge settling, which means slab replacement or a raised floating-floor system gets discovered mid-project. We run the inspection first, write allowances into the contract, and price every surprise approval in writing before we demo. Call (254) 602-5618 and ask Russ Delmar how we handle the unknowns on an older Sherman Oaks lot.
Yes, because Sherman Oaks sits inside City of Los Angeles, which allows a JADU plus a full detached ADU on a standard R1 zoned lot. That layered configuration is not permitted in Burbank or Glendale under their municipal codes. We confirm your lot’s eligibility during the consultation and build both units into the written plan from the start.
Your home was likely built before the quake, and if it was repaired afterward, those foundation patches, rebuilt garages, or soft-story retrofit records live in the LADBS permit file. If the paperwork doesn’t match the physical foundation, the ADU plans have to be corrected before submittal. We reconcile that history as step one so your build doesn’t stall at plan check. Call (254) 602-5618 for a free estimate that starts with the permit file, not the sales pitch.
Almost never. Sherman Oaks garage pours from that era are typically 3.5 inches thick, uninsulated, and frequently cracked from Northridge settling. A habitable-space conversion requires an insulated slab of adequate thickness and proper drainage, which usually means replacement or a raised floating-floor system. We caught a hairline crack running through a stem wall on Libbit Avenue that the permit file never showed, and we priced the fix in writing before the demo crew touched it.
Yes on both counts. Sherman Oaks summers routinely hit 100 – 108°F, so the ADU needs a right-sized mini-split for Title 24 and actual livability. If your parcel sits along the Mulholland Drive corridor in a Very High Fire Hazard Severity Zone, the wall assemblies, roof, and defensible space all have to meet fire-rated standards. Both factors affect the written price, and both are in our first estimate. Call (254) 602-5618 to schedule your free assessment.
