Fast, Reliable ADU Builders Across Irvine
If you’re searching for ADU builders in Irvine, the first thing to understand is that this city runs on a dual-approval system you won’t find at the same scale anywhere else in Orange County. Every ADU here needs a city permit plus sign-off from your village’s HOA architectural committee, and the second review dictates materials, colors, roof profiles, and even window mullions. We handle both tracks from day one, so your project doesn’t stall with a half-open garage bay while a committee meets. Call (254) 602-5618 to talk through your lot and what’s buildable.
Lodgewick ADU Builders is the ADU company of the Kingswell family, built since 2010 on one promise: a written price before work begins, a real arrival window, a clean job site, and a written guarantee on every project. Russ Delmar leads our ADU Builders team, and every crew member on an Irvine job is background-checked and uniformed. This matters when your rear yard becomes a construction site for three to six months. You should always know who’s on your property, and we make that a given.
Why Lodgewick ADU Builders Is Irvine’s Preferred ADU Builders Company
Irvine homeowners repeatedly tell us the same thing: they’ve been quoted one number and billed another, or they’ve had a crew disappear mid-project. We don’t work that way. The Kingswell Guarantee means your price is in writing before we start, your arrival window is defined, and if the work isn’t done right within 365 days, we come back and make it right. That’s written down and handed to you before the first nail goes in.
Our familiarity with Irvine specifically means we show up already knowing your village’s architectural guidelines, not discovering them at the submittal stage. We know that Woodbridge and University Park are loaded with single-car garages from the 1970s and 80s that convert beautifully into JADUs. We know that Great Park Neighborhoods homes have different lot geometries than Northwood. We know that Shady Canyon-adjacent properties may trigger wildfire-hardening requirements. That local knowledge compresses months off typical timelines.
Every call to Lodgewick is answered by a live person, 24 hours a day, seven days a week. That means when you call at 9 p.m. with a question about your submittal packet, you get Russ or a member of his team, not a voicemail loop.
ADU Plans in Irvine
ADU Plans in Irvine are where dual-approval reality hits hardest. Before we draft a single elevation, we pull your village’s CC&R design standards and the city’s zoning requirements side by side. Irvine is one of the most comprehensively HOA-governed cities in California, and the architectural committee typically requires your ADU’s exterior palette, roof tile profile, and window style to match the primary home’s original elevation exactly. A plan set that sails through the city can still get rejected by the committee for a paint sheen or trim detail.
Our plan sets for Irvine projects run from about $4,500 to $9,800 depending on ADU size and whether structural engineering or Title 24 energy modeling is already included. Detached two-bedroom ADUs land at the upper end; a garage-conversion JADU plan set typically runs $3,800 to $6,200. Every plan set includes the HOA submittal package with elevation drawings keyed to your home’s recorded finish schedule.
What the submittal packet contains
We assemble a complete packet: site plan showing setbacks and lot coverage, floor plan, all four elevations, roof plan, finish schedule with exact stucco texture and paint codes, window schedule, and a written narrative explaining how the ADU matches the primary home’s original elevation. The HOA architectural committee in Irvine reviews against CC&Rs that predate AB 670, and while they cannot prohibit an ADU outright, they absolutely control exterior appearance.
Sequencing plan review with construction start
We file the city permit and the HOA submittal in parallel, not sequentially. That’s the difference between starting framing the week approvals land and staring at a hole in your garage wall for six weeks. In Irvine, plan review plus HOA review typically adds four to ten weeks to the calendar, and we build that window into the schedule from day one.
ADU Contractor in Irvine
An ADU Contractor in Irvine is only as good as their sequencing discipline. Because nearly every Irvine village operates under Irvine Company-era CC&Rs with an architectural review committee, the contractor who files the city permit and then discovers the HOA review exists is the contractor who leaves your rear yard torn open for two months. We don’t do that. We track both approval tracks on a shared calendar you can see, and we don’t schedule demolition until both signatures are in hand.
On the construction side, Irvine’s housing stock is overwhelmingly post-1970 stucco-and-concrete-tile tract construction with standardized, often modest lots. Rear-yard depths in older villages like Woodbridge and Turtle Rock frequently cap detached ADU footprints at 500 to 700 square feet before setback and lot coverage rules bite. Courtyard and zero-lot-line layouts common in 1980s and 90s attached product make garage-conversion JADUs the highest-value path, not an afterthought.
Detached ADU construction in Irvine rear yards
A detached one-bedroom ADU in Irvine typically runs $210,000 to $290,000 all-in, including design, permits, construction, and utility connections. Two-bedroom units run $280,000 to $380,000. The range reflects things like soil conditions, sewer lateral locations, and whether your property falls within a High Fire Hazard Severity Zone along the eastern edge near the Lomas Ridge interface, which can add $12,000 to $25,000 in hardening requirements.
Garage-conversion JADUs in older Irvine villages
A garage-conversion JADU in Irvine typically runs $95,000 to $160,000. In neighborhoods like Woodbridge and University Park, where single-car garages from the 1970s and 80s are common, these conversions are often the most economical way to add a rental unit or family suite. The catch is the dimensional and finish-match requirement: the HOA architectural guidelines still require the garage-door bay to be infilled with materials matching the original elevation exactly.
Trusted Brands We Service in Irvine
We work hands-on with established ADU manufacturers and material suppliers so Irvine homeowners get matched to the right system for their lot, budget, and HOA constraints, not whatever product is easiest to source. For prefab and panelized builds, we install Abodu and Cover units where lot dimensions and committee approval allow. For projects requiring exact stucco texture and trim profile matching, James Hardie siding and trim let us key the new elevation to the original recorded drawings. We also have direct experience with Dvele for homeowners pursuing high-performance detached units on larger lots in the Great Park Neighborhoods and Northwood. Inventory moves, but our familiarity with the brands means we can tell you honestly what fits your village and what the committee will push back on.
Common ADU Builders Problems We See in Irvine Homes
- City permit filed, HOA packet never submitted. The crew starts demolition, the HOA architectural committee reviews the design three weeks later, and rejects the roof tile profile or window mullion. Now the job sits half-open while you re-file. We file both on the same day, every time.
- Modern cladding on a post-1970 tract home. An owner loves the idea of standing-seam metal or fiber-cement panel cladding. Irvine committees routinely reject anything that doesn’t mirror the primary home’s stucco texture, concrete-tile roof, and window style. We tell you this before you pay for a design that won’t pass.
- Detached ADU setbacks underestimated. Rear-yard depths in Woodbridge, University Park, and parts of Northwood often run shallower than owners assume. A 750-square-foot detached unit that fits on paper in another city may not clear Irvine’s setback and lot coverage rules. We survey the yard before the plan set is finalized.
- Wildfire-zone surprises near Shady Canyon. Properties along the eastern edge near Shady Canyon and the Lomas Ridge interface sit inside Orange County’s High Fire Hazard Severity Zones. That triggers ember-resistant venting and ignition-resistant siding requirements that add cost and permitting complexity. We flag this in the estimate, not as a change order mid-build.

FAQs About ADU Builders in Irvine
Yes. Nearly every Irvine village operates under Irvine Company-era CC&Rs with an architectural review committee, and while California’s AB 670 prevents HOAs from outright prohibiting ADUs, they still control exterior appearance. You need both approvals before construction starts, and we file both submittals in parallel. Call (254) 602-5618 to have us pull your village’s specific design standards.
Plan for an additional four to ten weeks on top of city permit review. Committee meeting cadence varies by village; some meet monthly, others twice a month. We sequence the HOA submittal and the city permit filing on the same day so the two reviews run concurrently rather than back-to-back, which is what typically causes stalled projects.
A complete packet includes a site plan, floor plan, all four elevations, roof plan, finish schedule with exact stucco texture and paint codes, window schedule, and a written narrative explaining how the ADU matches the primary home’s original elevation. The finish schedule is where Irvine committees focus hardest. We handle the packet assembly so you don’t have to interpret CC&R language.
Often yes. These villages have large numbers of single-car garages from the 1970s and 80s, and the existing garage footprint typically clears setback rules without needing a rear-yard build. The constraint is finish matching: the HOA requires the infilled garage bay to match the original elevation’s stucco texture, paint color, and trim profile exactly. We source materials like James Hardie panels and match exterior finishes to the recorded elevation drawings so the bay reads as original wall, not a covered opening.
Yes. Properties along Irvine’s eastern edge fall inside Orange County’s High Fire Hazard Severity Zones, which triggers ember-resistant venting, ignition-resistant siding, and sometimes defensible-space landscaping requirements. These add roughly $12,000 to $25,000 to a typical ADU and must be designed into the plan set from the beginning. We identify this during the initial site assessment, before you’ve committed to a design that needs rework.
