Why Ellery ADU Studio Is Woodland’s Preferred Garage Conversion ADU Company

Ellery ADU Studio has designed, permitted, and built over 900 ADUs since 2015, and Woodland represents a meaningful share of that portfolio because the city’s housing stock matches what our design-build model handles best: older garages with real structural issues that need engineering, not just drywall. We’ve converted detached garages on the deep lots north of Main Street, where 1920s Craftsman homes sit 60 feet back from the curb, and we’ve partitioned attached garages in the southeast tract neighborhoods where the 1950s slab-on-grade construction demands a different utility approach. The permit set we produce reflects what we actually find in Woodland garages, not a generic plan pulled from a template.

Nadia Ellery founded the studio in 2015, the year California’s ADU permitting landscape shifted dramatically, and she built the practice around a single contract: the drawings, the permit set, and the construction are one written price, eliminating the designer-versus-builder blame gap that stalls projects. Woodland customers work directly with our design-build team, not a rotating cast of subcontractors with no stake in the outcome. When something goes wrong on a Woodland job, there’s one entity accountable. That’s the entire point.

Every project carries the 365-Day Done Right Promise in writing before we start: if the finished ADU isn’t built to the permitted drawings, we make it right. Under Haven Standard Clause 1, the price is written before any work begins, so a Woodland homeowner never hears the phrase “call for a quote” from us. The number is already on the page.

Key Takeaways for Woodland Garage Conversions

• Typical all-in cost in Woodland: $165,000 to $245,000, with detached garages at the top of that range.
• Downtown parcels listed in the city’s historic resources inventory can trigger a design-compatibility review before permits are issued.
• Every Woodland ADU needs a dedicated HVAC system sized for 105°F summer days, not a shared duct tap from the main house.
• Slab-on-grade utility stubs on 1950s east Woodland lots frequently require re-routing once trenching begins.
• UC Davis rental demand keeps Woodland garage conversion ADUs cash-flowing at near-Davis rents.

Our Garage Conversion ADU Services in Woodland

Attached Garage Conversion

An attached garage in Woodland means the ADU shares a wall with the main house, which helps with plumbing and electrical runs but creates its own compliance issues: the shared wall must meet Yolo County fire separation standards, and the existing footing may need verification before the city signs off. We’ve converted attached garages across the 95776 and 95695 zip codes, and the process usually moves faster than a detached conversion because the utility connections are closer. Expect $155,000 to $195,000 for a well-finished attached conversion in Woodland.

Detached Garage Conversion

Detached garages dominate the older Woodland neighborhoods west of Highway 113, where lots are deep and the garages are genuine structures built between 1910 and 1940. These buildings present what our team calls the “Woodland three”: outdated wiring, undersized framing, and no sill-plate waterproofing. We price the repair scope into the written contract as an allowance, then bring any discovered condition back as a line-item approval before work proceeds. Detached conversions in Woodland typically run $180,000 to $245,000 because the building envelope needs more from the start.

Carport Conversion

A carport conversion in Woodland is rare but feasible on the mid-century lots east of East Street, where carports replaced garages entirely. The challenge is that a carport has no framed walls, so we’re building the envelope from the ground up: new foundation, new wall framing, new roof structure. The cost lands around $140,000 to $180,000 in Woodland, and the city treats it as new construction for permitting purposes, which means the full plan review cycle applies.

Garage Partition & Bathroom Add

On Woodland lots where the garage is oversized, we often partition the space and add a full bathroom within the existing footprint rather than converting the whole structure. This keeps part of the garage for storage or parking while creating a rentable or in-law unit on the other side. The approach works well in the Craftsman neighborhoods north of Main Street, where garages run 400 to 600 square feet and a partition plus bath at $95,000 to $140,000 pencils out faster than a full conversion.

Garage JADU

A Junior ADU inside an existing garage is the budget path for Woodland homeowners who want rental income without a full kitchen build-out. Yolo County allows JADUs up to 500 square feet within an existing structure, and a garage JADU in Woodland typically runs $85,000 to $130,000 including the required separate entrance and efficiency kitchen. We’ve placed several of these in the 95776 tract neighborhoods, where the smaller footprint matches the tighter lots and the UC Davis rental pool fills them quickly.

Trusted Brands We Service in Woodland

Our Garage Conversion ADU team specifies and coordinates prefab and modular systems from Abodu, Cover, and Dvele within the same single contract that covers design, permitting, and construction. That means a Woodland homeowner who wants a prefab shell for the framing phase gets the same written-price guarantee as a fully custom build, with the manufacturer’s warranty documented alongside our own 365-Day Done Right Promise. For exterior cladding and the hard-wearing surfaces that hold up to Woodland’s summers, we specify James Hardie fiber cement routinely. It resists the heat cycling that cracks vinyl siding on 1950s garages within a decade.

Common Garage Conversion ADU Problems We See in Woodland Homes

• Knob-and-tube wiring in pre-1940 garages. Older detached garages near downtown Woodland frequently still carry knob-and-tube circuits. The city won’t pass a garage conversion with live knob-and-tube, so the panel replacement and re-wire must be priced before the permit set is submitted, not discovered mid-rough-in.
• Undersized roof rafters on 1920s structures. We’ve opened Woodland garages where 2×4 rafters spanning 12 feet have sagged visibly under decades of valley heat. A conversion that doesn’t engineer a reinforcement plan will fail structural review, so our Woodland proposals always include a roof-framing allowance.
• No sill-plate waterproofing on slab foundations. Woodland’s winter rains saturate the ground around older garage slabs, and without a moisture barrier at the sill plate, the bottom plates rot within a few wet seasons. We write a moisture barrier and sill replacement into the baseline scope for any pre-1960 Woodland garage.
• Slab-on-grade utility stubs that don’t match the plan. On 1950s and 1960s east Woodland lots, the sewer and water stubs often run under mature trees or cross the property in a way the original tract maps don’t show. We camera-inspect the sewer line before we commit to a fixture layout, because re-routing after trenching starts is the single most expensive surprise in a Woodland conversion.

How We Handle the Unknown in Older Woodland Garages

Our Garage Conversion ADU process starts with an inspection that opens the walls, not one that walks the perimeter and guesses. On a late-1920s Craftsman near downtown, our crew opened the detached garage and found knob-and-tube wiring buried in the wall, undersized 2×4 rafters that had sagged under decades of valley heat, and no sill-plate waterproofing. We wrote the replacement panel, engineered roof reinforcement, and a new moisture barrier into the change order only after the owner approved a line-item quote, then brought the finished ADU to a UC Davis PhD student within the fall semester. That’s the model: inspection first, allowances written into the contract, and any surprise priced and approved in writing before we touch it. Haven Standard Clause 5 locks the scope at signing, so no door-side upsells, no scope creep.

The Woodland Cost Drivers No Generic Page Tells You About

Woodland is the primary bedroom community for UC Davis and the City of Davis, which enforces some of California’s most restrictive slow-growth policies. Measure D requires voter approval for major residential development, so rental demand within a 10-minute commute of UC Davis is chronically unmet. That means a Woodland ADU can realistically command near-Davis rents while being built on significantly cheaper Woodland land, a return-on-investment ratio that doesn’t exist for ADUs in Sacramento, Dixon, or Vacaville. But the same market that makes Woodland ADUs profitable also sets the performance bar: a garage conversion permitted without a dedicated HVAC circuit fails a 105°F summer cooling load and becomes unrentable to UC Davis tenants. Student renters in Woodland check the cooling system first. We size a dedicated HVAC system for every detached ADU we build here, because the cooling load is a code necessity in the Sacramento Valley, not an upgrade.

Portions of Woodland’s older residential streets near downtown are documented in the city’s historic resources inventory. A proposed backyard ADU on an affected parcel can trigger a design-compatibility review for materials, roofline, and massing, a step that doesn’t apply in most Sacramento-area suburbs and can add weeks to permitting for contractors who don’t identify it early in the pre-application stage. We run the historic-inventory check before we draw the first elevation, and we write the review timeline into the project schedule so there are no surprises at the counter. A pre-application review that misses this listing is the most avoidable delay in Woodland ADU permitting.
