Lodgewick ADU Builders is the ADU company of the Kingswell family, established in 2010. We specialize in accessory dwelling units, garage conversions, and home additions – a lodge is a small house on a larger property, which is exactly what an ADU is. Led by Russ Delmar, our team serves Chino from our Inland Empire office, and we know this city’s housing stock better than most contractors who just pass through.

Why Lodgewick ADU Builders Is Chino’s Preferred Home Addition Contractor Company

Chino homeowners don’t need another contractor who talks fast and disappears. They need someone who knows that older ranch homes near downtown Chino hide aluminum branch wiring and undersized 2×4 framing behind those 1950s and 1960s walls. They need a company that puts every commitment in writing before a single nail is driven. That’s the Kingswell Guarantee: a written price before work begins, a defined arrival window, a clean job site, and a written guarantee on every job.

Every Chino project gets the same treatment. Russ Delmar and our crew walk the site first, inspect what’s actually there, and give you a written price that accounts for what we know we’ll find – not what we hope we’ll find. If something unexpected shows up after walls are open, it gets priced and approved in writing before we touch it. That’s not a sales pitch. That’s how we’ve operated since 2010, and it’s why homeowners from the College Park area to the older streets around Chino Avenue call us back when they’re ready for the next project.

Our 365-Day Done Right Promise covers every addition we build in Chino. If it’s not done right, we make it right, and that commitment is in writing on every project. A live person answers our phones 24/7 – no voicemail loops when you have a question about your build or your guarantee.

Garage Addition Contractors in Chino

Garage Addition Contractors in Chino deal with a specific set of conditions that most builders in neighboring cities never see. Chino’s identity as a former dairy capital means the city holds an unusual concentration of oversized residential lots – many 9,000 to 15,000+ square feet – carved from converted agricultural parcels. That rear-yard depth makes detached garage additions and garage-to-living-space conversions physically possible in ways they simply aren’t on the 4,000 to 5,000 square foot lots typical of Chino Hills or Ontario Ranch. The lot size is rarely the limiting factor here.

A garage addition in Chino typically runs $45,000 – $95,000 depending on whether you’re extending an existing garage, converting an attached space, or building a new detached structure with living quarters above. Permit fees, engineered plans, and the geo-soil work we’ll discuss below all factor into that number before we ever hand you a quote.

Detached Garage Additions on Dairy-Parcel Lots

Chino’s converted agricultural parcels bring one issue no one in a newer subdivision deals with: expansive clay soil. That soil moves when it gets wet and shrinks when it dries, which is why so many original garage slabs around this city are cracked and shifted. We order the geotech report alongside the design package instead of after plan check, so deeper footings or piering are priced into your written estimate before demo starts – not dropped on you as a change order later.

Garage Conversions and Tied-In Additions

When we open the wall between a Chino home and a garage addition, we’re prepared for what’s behind it. Aluminum branch wiring from the 1960s, 2×4 framing that doesn’t meet current lateral load code, and failed waterproofing at the transition are all common in this city’s housing stock. We flag those as allowances in the contract up front, and anything we find gets approved by you in writing before we touch a single stud.

Bathroom Addition Contractor in Chino

A Bathroom Addition Contractor working in Chino has to respect something the climate demands: this inland basin traps heat, regularly exceeding 105°F in summer. When we add a bathroom to a Chino home, we’re thinking about dedicated HVAC runs, proper insulation, and exhaust fans that can actually handle a space that’ll bake for four months a year. A bathroom addition here typically costs $28,000 – $55,000, with higher-end builds touching $70,000 when they include heated floors or custom tile work.

Bathroom Additions in Older Ranch Homes

Homes near downtown Chino – the 1950s through 1970s single-story ranches – often have a single bathroom that was never meant for a family of four. Adding a second or third bathroom to these homes means working with original cast-iron plumbing, concrete foundations that predate modern anchoring codes, and wall cavities packed with materials no one’s touched in sixty years. Every one of those conditions is predictable, and we write our quotes accordingly.

Bathroom Additions in Newer Tract Homes

College Park and similar master-planned tracts from the 2000s and 2010s present a different set of constraints: tighter lot lines, HOA CC&Rs that can restrict plumbing location, and post-tension slab foundations that require stud detection and careful coring. We work with the HOA’s architectural review process from day one so your bathroom addition doesn’t stall at the approval desk.

Trusted Brands We Service in Chino

We’re hands-on with a number of prefab and materials brands Chino homeowners ask about: Abodu, Cover, and Dvele among them. Whether you’re planning a full ADU from a prefab manufacturer or an addition built with James Hardie siding and conventional framing, we match the system to your lot, your budget, and your timeline. We stock and source parts locally for Chino customers, and our suppliers deliver to this area weekly, so material runs don’t hold up your permit schedule.

Common Home Addition Contractor Problems We See in Chino Homes

• Aluminum branch wiring from the 1960s. Chino’s ranch-era homes frequently contain aluminum circuits that fail modern inspection standards. Opening a wall for an addition triggers a code upgrade on anything we touch – and we flag that before we ever open the wall.
• Expansive clay soil on former dairy parcels. The clay under many Chino lots expands and contracts with moisture, cracking slabs and shifting framing. A soil engineering report adds roughly 2 – 4 weeks to permitting, but skipping it means change orders you never saw coming.
• Failed waterproofing at garage-to-house transitions. Chino’s summer heat and occasional heavy rain wreak havoc on flat transitions between attached garages and living space. We inspect first, price fixes as a written allowance, and you approve everything before work begins.
• HOA restrictions in newer Chino tracts. College Park and other HOA-governed communities have CC&Rs that can limit addition size, placement, and even exterior materials. We pull HOA guidelines on day one and design within them instead of fighting them after plans are drawn.
