Garage Conversion ADU in North Hollywood - Plans, Permits & Build, One Fixed Price

Fast, Reliable Garage Conversion ADU Across North Hollywood

If you own a home in North Hollywood with a detached garage sitting under-used, you’re looking at one of the best ADU conversion opportunities in Los Angeles. Most garage conversions here run $145,000-$225,000 all-in, drawings through final inspection, and the numbers pencil out faster than almost anywhere else in the Valley. That’s because North Hollywood sits inside the Metro B Line transit corridor, which triggers LA City’s most permissive ADU parking exemptions. You don’t have to replace the parking you convert, and that single fact saves $20,000-$40,000 before we even open the walls. Call (971) 497-2402 and we’ll walk you through what your specific garage can become.

We design and build Garage Conversion ADU projects here every month. Our studio coordinates the drawings, the permit set, and the construction under one contract at one written price. No designer pointing at the builder when something’s off. The schedule, the scope, and the price are agreed before work begins.

Why Ellery ADU Studio Is North Hollywood’s Preferred Garage Conversion ADU Company

Nadia Ellery founded this studio in 2015, the same year California’s ADU permitting landscape shifted. Since then we’ve designed, permitted, and built more than 900 ADUs, and every single one had a written price before work started. That’s not a marketing line. It’s Haven Standard Clause 1, and we put it in writing before we touch a drawing.

North Hollywood homeowners keep hiring us for a reason that shows up in the reviews: we document everything. Every site visit includes a photo record of what we found and what we did. When we tell you the existing slab is 4 inches and within range for a conversion, you get photographs, not a voice note. When we flag a foundation issue on a 1950s detached garage near the NoHo Arts District, the photo record backs the line item. Our crews are background-checked and uniformed. Our license number appears on every page we send you, verified, not claimed.

We know North Hollywood’s blocks. The post-WWII ranch grid. The rear alleys. The specific way the B Line terminus changes your ADU math. That local knowledge is why our North Hollywood projects move through plan check with fewer corrections, and why our estimates here are tighter than they’d be from a studio working out of a different part of the county.

Our Garage Conversion ADU Services in North Hollywood

Detached Garage Conversion

This is the dominant project type in North Hollywood, because the dominant housing stock was built for it. Most homes south of Burbank Boulevard and east of Vineland Avenue are 1950s-1960s single-story ranches on 6,000-7,500 sq ft lots, with detached two-car garages set back from the street. Those garages sit inside the Metro B Line’s ½-mile transit corridor, which means converting them triggers zero parking replacement requirements. A typical detached garage conversion in North Hollywood runs $155,000-$225,000 for a 400-500 sq ft unit, and the parking exemption alone removes a $20,000-$40,000 line item that would apply in Van Nuys or Reseda.

Garage Partition & Bathroom Add

Sometimes you don’t need a full conversion. If your two-car garage in the Valley Village side of North Hollywood is 20 by 22 or larger, we can partition it into a rental studio and leave the remaining bay for storage or a workshop. A partition and bathroom add typically runs $65,000-$95,000 in North Hollywood, including the sewer tie-in, a Title 24-compliant mini-split, and the permit set. This is the most common first step for owners who want rental income without losing the entire garage.

Garage JADU

A Junior ADU carved from a garage is the least expensive legal rental unit you can build in North Hollywood. Because LA City caps JADUs at 500 sq ft and allows them within an existing structure’s footprint, your detached garage can become a JADU for $85,000-$120,000, depending on whether you’re converting half the garage or the whole thing. The trade-off: JADUs must share the primary residence’s sewer line, which in North Hollywood’s older homes sometimes means a sewer upgrade. We flag that in the permit set before you sign anything.

Carport Conversion

Some North Hollywood lots, particularly east of Lankershim Boulevard, have carports rather than fully enclosed garages. A carport conversion runs $120,000-$170,000 and includes enclosing the structure, upgrading the foundation to meet current code, and adding a bathroom and kitchenette. The advantage: carports are rarely counted as nonconforming structures, so the permit path is shorter. The disadvantage: you will likely be building wider footings than planned, because a carport slab wasn’t engineered for habitable load.

Trusted Brands We Service in North Hollywood

When a North Hollywood homeowner wants a prefab or modular system, we specify and coordinate it within our single contract. That includes Abodu and Cover for turnkey detached units, Dvele for high-performance panelized builds, and James Hardie siding where the existing home’s stucco needs relief. Because we stock and coordinate these systems ourselves rather than subbing the ordering to a third party, our North Hollywood timelines don’t slip when a manufacturer is slow. If you already have a quote from a prefab vendor, bring it in. Our Free Second Opinion applies to any written estimate, including factory-direct pricing.

Common Garage Conversion ADU Problems We See in North Hollywood Homes

• Ignoring the transit-zone parking exemption. Owners who don’t know the B Line corridor rules sometimes design for off-street parking replacement, or worse, their HOA rejects the plans for a front-facing driveway that wasn’t needed. That’s a $20,000-$40,000 mistake. We check your parcel against the transit overlay as the first step in the permit set, before any drawings are locked.
• Under-insulating the original detached garage. North Hollywood regularly hits 105°F in summer. A 1950s single-wall garage with no insulation will fail Title 24 energy compliance and produce an ADU nobody wants to rent in August. We upgrade to California Title 24 insulation standards and specify dedicated mini-split HVAC on every detached conversion here. That spec would be over-engineered in Santa Monica. Here it’s the minimum for habitability.
• Building a front-facing entrance when a rear alley is platted. A large share of North Hollywood’s residential blocks have rear alleys from the original 1940s-1950s subdivision grid. An alley-facing entry gives your tenant fully independent access and eliminates front setback conflicts. We routinely design detached units with alley entries, and we see owners who didn’t know that was possible until we showed them the platted easement.
• Discovering a sewer line that can’t handle the new bathroom. Many of North Hollywood’s older ranch homes have original cast-iron sewer laterals. Adding a full bathroom to a detached garage sometimes requires a lateral replacement or a pump-and-lift system. We photograph the condition during discovery and give you a written line item before construction starts, under Haven Standard Clause 5. No door-side upsells. No scope creep.
