ADU in Woodland, CA
ADU Design & Permitting in Woodland usually starts with a site assessment, because the city’s housing stock splits into two very different permitting realities: 1890s-1930s historic-core homes on deep parcels, and 1950s-1970s tract homes on tighter lots with slab foundations. Most Woodland projects we see land between $95,000 and $420,000 all-in, depending on whether you’re converting an existing garage or building new detached construction. If you’re weighing an ADU here, call (971) 497-2402 and we’ll walk you through what your specific property can support.
Why Woodland Homes Are Different
Woodland is the primary rental-market relief valve for UC Davis and the City of Davis, where Measure D requires voter approval for most major housing development. That means a Woodland ADU can command near-Davis rents while being built on significantly cheaper Woodland land, which changes the math on how much square footage makes sense to build. The historic core around downtown holds late-Victorian and Craftsman homes from the 1890s through the 1930s, often with detached garages framed in old-growth redwood that are surprisingly good conversion candidates. The east and south sides are 1950s-1970s tract stock, slab-on-grade, with tighter setbacks and utility routing that needs earlier attention. Summers here routinely exceed 105°F, so a detached ADU needs a properly sized HVAC system on its own meter, not a duct tap off the main house. And some streets near downtown sit in the city’s historic resources inventory, which can trigger a design-compatibility review for materials, roofline, and massing that most Sacramento-area suburbs don’t require.
Our Main Woodland Services
Woodland homeowners most often call us about two projects: converting an existing garage into rent-ready square footage, and building a new detached unit in the backyard. Both carry different permitting paths and different price structures in Woodland.
Garage Conversion ADU in Woodland
Woodland’s historic-core homes often have detached garages on deep parcels, and many of those older buildings are better framed than what we see in newer Sacramento subdivisions. The catch: if your garage sits on a lot in the historic resources inventory, expect a design-compatibility review before you pull permits. We handle that step as part of the permit set rather than letting it surface mid-construction. Garage Conversion ADU in Woodland pricing starts with a written quote before any work begins.
New Detached ADU in Woodland
A new detached ADU on a Woodland tract-home lot means early attention to setback compliance and utility stub-out routing, since the 1950s-1970s parcels run tighter than the historic core. The 105°F summers also mean your cooling load sits on a dedicated meter, which affects both panel sizing and the solar-plus-storage conversation. New Detached ADU in Woodland covers the full path from site assessment through final inspection at a single written price.

ADU Design & Permitting in Woodland
ADU Design & Permitting in Woodland means producing a permit set that accounts for two very different city realities: historic-core compatibility review on the west side, and tight-lot setback math on the east and south. A 1950s tract home with slab-on-grade construction and a shallow side yard needs a different foundational approach than a 1910 Craftsman on a deep parcel with an existing detached garage. We handle the full design and permit path under one contract at one written price, through our ADU Design & Permitting service.
Site Assessment
Signs you need it
You have a parcel in north or east Woodland where you’re not sure whether the city’s setback rules will allow the size of ADU you want.
What it costs in Woodland
Site assessments in Woodland run $450-$1,200, depending on whether we’re evaluating a simple conversion or full new construction with utility routing questions.
How we do it
We measure the lot, check the zoning overlay, identify any historic-resources trigger, and document existing utility stubs and slab conditions in a written site report with photos.
ADU Design & Blueprints
Signs you need it
You’ve decided on an ADU but need a complete permit set that Woodland’s building department will approve without rounds of corrections.
What it costs in Woodland
Design and blueprint packages for Woodland ADUs typically run $8,000-$20,000, depending on size, site complexity, and whether historic compatibility review applies.
How we do it
We produce a full permit set: site plan, floor plan, elevations, structural drawings, Title 24 energy compliance, and the written scope that locks the project before construction starts.
Permit Application
Signs you need it
You want someone else to manage Woodland’s submittal, review cycles, and the inevitable correction requests from the building department.
What it costs in Woodland
Permit application management in Woodland adds $2,000-$6,000 to a project, covering our time on submittal, revision responses, and city coordination.
How we do it
We submit the permit set, track the review, respond to every correction in writing, and keep you updated with each city response until the permit is issued.

|---|---|
| Site assessment | $450-$1,200 |
| Design & blueprints | $8,000-$20,000 |
| Permit application management | $2,000-$6,000 |
How long does ADU design and permitting take in Woodland?

Will my Woodland ADU need design-compatibility review?
Only if your property sits within the city’s documented historic resources inventory, mostly concentrated near downtown. We check that early in the site assessment so it never becomes a mid-project surprise. Call (971) 497-2402 for a property-specific answer.
Junior ADU & Interior Conversion in Woodland
A Junior ADU in Woodland often means carving rentable space out of an existing garage, basement, or oversized bedroom in one of the city’s 1950s-1970s tract homes, where the parcel won’t support a detached unit. Those slab-on-grade homes make attached conversions the practical path, and Woodland’s rental demand near UC Davis means even a 350-square-foot JADU can generate meaningful income. Through our Junior ADU & Interior Conversion service, we handle the design, permit set, and build under one contract.
Interior JADU
Signs you need it
You have an oversized primary bedroom or a den with its own exterior wall and want to convert it into a rentable unit with a private entrance.
What it costs in Woodland
Interior JADU conversions in Woodland typically run $70,000-$140,000 all-in, from drawings through final inspection.
How we do it
We frame the interior separation, add the private entrance, run new electrical and plumbing as needed, and produce the permit set that documents every wall before we open one.
Room-to-ADU Conversion
Signs you need it
You have an existing bonus room or workshop space that’s already conditioned but lacks a kitchenette, bath, or legal egress.
What it costs in Woodland
Room-to-ADU conversions in Woodland run $55,000-$120,000, depending on how much plumbing and electrical infrastructure the existing space already has.
How we do it
We add the kitchenette and bath, upgrade the electrical panel if needed, bring egress up to code, and document the work with a photo record at every visit.
What Junior ADU & Interior Conversion Costs in Woodland
| Item | Typical range in Woodland |
|---|---|
| Interior JADU | $70,000-$140,000 |
| Room-to-ADU conversion | $55,000-$120,000 |
| Above-garage ADU | $140,000-$220,000 |
Does a JADU in Woodland need its own kitchen?
Yes, Woodland follows California JADU standards: you need an efficiency kitchen, which means a small cooking appliance, a sink, and storage. Full-size ranges aren’t required. Call (971) 497-2402 and we’ll confirm the current code path for your project.
Can I convert part of my Woodland house without a separate address?
A JADU shares the primary residence’s address in Woodland, which simplifies permitting and avoids the utility-meter complications of a detached unit. It does mean the owner must occupy either the main house or the JADU. Call (971) 497-2402 to talk through your layout.
ADU Site Prep & Utilities in Woodland
ADU Site Prep & Utilities in Woodland means solving the two issues that end most backyard projects before they start: slab conditions on tract-home lots and electrical service capacity on older panels. A 1950s home in east Woodland with a 100-amp panel and a shallow side yard needs both a service upgrade and careful trench routing before any foundation work happens. Our ADU Site Prep & Utilities team handles the below-grade and utility work as part of the same contract, so the drawings, the panel, and the trench are all one scope.
Foundation & Grading
Signs you need it
You’re building a new detached ADU on a Woodland tract-home lot where the existing pad slopes toward the house or the soil hasn’t been tested for bearing capacity.
What it costs in Woodland
Foundation and grading for a Woodland detached ADU runs $12,000-$35,000, depending on soil conditions, slab size, and whether piers are required.
How we do it
We test the soil, grade the pad, pour the slab or install piers, and document the entire sequence with photos you receive at each visit.
Electrical Panel Upgrade
Signs you need it
Your Woodland home still runs a 100-amp panel and the new ADU needs its own meter and a dedicated HVAC circuit.
What it costs in Woodland
Panel upgrades for Woodland ADUs run $3,500-$8,500, including the new sub-panel, meter, and city inspection.
How we do it
We upgrade the main panel, add the ADU sub-panel, run the feeders through properly sized conduit, and pull the electrical permit under the same written scope as the build.
What ADU Site Prep & Utilities Costs in Woodland
| Item | Typical range in Woodland |
|---|---|
| Foundation & grading | $12,000-$35,000 |
| Electrical panel upgrade | $3,500-$8,500 |
| Plumbing lateral | $4,000-$12,000 |
Do I need a separate water meter for a Woodland ADU?
Not typically. Woodland allows most ADUs to share the primary water service, though the city may require a separate shutoff valve at the ADU. We confirm this during the site assessment. Call (971) 497-2402 for your parcel’s specifics.
How deep are utility trenches in Woodland?
Gas lines in Woodland run 18 inches below grade, electric typically 18-24 inches, and water 24-30 inches depending on the district. The 105°F summer heat means we schedule trenching in the morning when crews can work safely. Call (971) 497-2402 to talk about your site.

FAQs About ADU in Woodland
Site assessments usually happen within a week of your call. The full timeline from assessment to permit issuance in Woodland runs 4-8 months, depending on design complexity and whether historic review applies. Call (971) 497-2402 to get a schedule for your specific property.
Most Woodland neighborhoods predate HOAs or have none at all. If your subdivision does have covenants, California Civil Code 4751 overrides any HOA restriction on ADUs, though architectural review may still apply. We check this during the site assessment.
Yes. Yolo County reassesses the added value of the ADU, typically 1% of the improvement value annually. Many Woodland owners offset this with rental income, which near-Davis demand makes consistently achievable. Call (971) 497-2402 and we can walk you through the math for your property.
If you’re weighing an ADU in Woodland and want a written price before any work starts, call (971) 497-2402. Nadia Ellery and our team will schedule a free site assessment, walk your parcel, and put the full project scope in writing with a documented photo record on every visit.

What Woodland 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."Every allowance was itemised at the start, so the finish selections did not turn into a surprise at the end."
