Fast, Reliable ADU Builders Across Upland
ADU construction in Upland typically runs $180,000 to $420,000 for a detached unit, with garage conversions landing between $95,000 and $190,000 depending on the condition of the existing structure and whether your parcel falls inside the city’s fire hazard overlay. Those numbers come from real projects we’ve priced across this city, not a national average that ignores what Upland’s zoning and terrain actually do to a budget. If you’re on a grove-era lot north of Foothill Boulevard, your quote will look different from a flat South Upland parcel, and we’ll explain exactly why before you sign anything. Our crews know Upland’s permit counter, its hillside setbacks, and its 100°F summer cooling demands. Call (254) 602-5618 and we’ll give you a written price, not a guess.
Why Lodgewick ADU Builders Is Upland’s Preferred ADU Builders Company
Homeowners in Upland hire us because we put the price in writing before a single nail is driven. That’s The Kingswell Way, and it’s what sets our ADU Builders team apart in this city. No change orders at the door, no “we discovered something” conversations that double the bill. We show up in the window we give you, keep the job site clean, and hand you a written guarantee before the work starts.
Russ Delmar leads our Upland projects, and he’s the person homeowners actually talk to when questions come up. Not a call center. Not a chatbot. A live person answers our phone 24 hours a day, seven days a week. Upland homeowners who’ve been burned before by contractors who disappear after the deposit tend to notice that.
We’ve built and converted ADUs across Upland, from the Craftsman bungalows near downtown to post-war ranch homes off Euclid Avenue and the oversized citrus-grove lots up by San Antonio Heights. That range matters. A builder who only knows new construction on flat suburban lots will miss things on a 14,000 sq ft hillside parcel. We don’t.
ADU Plans in Upland
ADU Plans in Upland are the difference between a project that sails through the permit counter and one that stalls for months. Upland’s planning department reviews every accessory dwelling unit against a patchwork of zoning districts, fire hazard overlays, and hillside grading rules that change block by block. Our planning work starts with a parcel-level review of your specific lot: zoning, VHFHSZ designation, setback requirements, sewer lateral condition, and panel capacity. We charge $2,500 to $6,500 for full ADU plans depending on whether it’s a garage conversion, a detached new build, or a prefab installation requiring site-specific engineering.
Parcel-Level Site Analysis
Before we draw a single line, we pull your parcel’s fire hazard overlay and confirm what the city will actually require. On North Upland lots above Foothill, that often means Chapter 7A ignition-resistant materials. On South Upland flat parcels, it usually doesn’t. Knowing that before we quote is what keeps your price honest.
Permit-Ready Construction Documents
We produce drawings the Upland building department can approve on the first submittal: floor plans, structural calculations, Title 24 energy compliance, and site plans showing setbacks and drainage. Every set includes the specifications for the HVAC, electrical panel, and sewer connection upgrades that Upland’s older housing stock routinely triggers.
ADU Contractor in Upland
An ADU Contractor in Upland has to do more than frame walls and hang drywall. This city’s housing stock from the 1920s through the 1960s means nearly every project involves a 100-amp panel upgrade, a clay or cast-iron sewer lateral replacement, or both. Our construction pricing runs $95,000 to $190,000 for garage conversions and $250,000 to $420,000 for detached two-bedroom ADUs, including all trade work, materials, and permit fees. We scope every line item before quoting so the number we write down is the number you pay.
Garage and Detached Structure Conversions
Upland’s original detached garages are often in decent structural shape, but the utilities feeding them rarely are. We handle the full conversion: foundation inspection and repair, panel upgrade to 200 amps, new sewer lateral if yours is original clay or cast iron, insulation, drywall, mini-split HVAC, and a full kitchen and bath build-out.
Prefab and Modular ADU Installation
We work with Abodu, Cover, and Dvele on prefab ADU installations across Upland. Prefab can shorten construction time by weeks, but Upland’s hillside parcels still need site work: grading, drainage, retaining walls, and utility trenching. We handle all of it and give you one written price for the whole job, not a factory quote plus a surprise site-work change order.
Trusted Brands We Service in Upland
We install and finish ADUs from Abodu, Cover, and Dvele, and we spec James Hardie siding on nearly every Upland project because it holds up to the Santa Ana winds and summer heat better than vinyl or stucco alternatives. Our crews know these systems cold: how the panels align, where the air sealing goes, what the factory doesn’t include, and what Upland’s inspectors will flag. That means quicker turnarounds and fewer mid-project surprises for you.
Common ADU Builders Problems We See in Upland Homes
- Fire hazard overlay surprises on North Upland parcels. A garage conversion above Foothill Boulevard gets flagged by the city’s GIS as VHFHSZ, triggering Chapter 7A ember-resistant vents, Class A roofing, and multi-pane glazing. Those materials can add $8,000 to $15,000 that a blind quote never included.
- Original 100-amp panels and clay sewer laterals. Upland homes built between the 1920s and 1960s almost always need a 200-amp panel upgrade and a lateral replacement before the city signs off on an ADU permit. A contractor who doesn’t check this before quoting is guessing.
- Mini-split oversizing on 100°F summer days. Upland sits on the Cucamonga alluvial fan at 1,200 to 1,500 feet elevation. Summer cooling loads are brutal, and an undersized unit means a tenant who can’t sleep in August. We size every system for Upland’s actual climate data, not a generic California average.
- Septic and well setbacks on grove-era acreage. Oversized North Upland lots carved from the old citrus groves often have septic systems and private wells. ADU placement has to respect those setbacks, and the county health department gets involved even when the city issues the building permit.

FAQs About ADU Builders in Upland
North Upland parcels above Foothill Boulevard sit inside the city’s Very High Fire Hazard Severity Zone, and Upland’s building department enforces CBC Chapter 7A ignition-resistant construction there. That means ember-resistant vents, Class A roofing, and multi-pane glazing that flat South Upland parcels don’t require. On a typical garage conversion, those materials add $8,000 to $15,000 before you consider grading or access challenges on hillside lots. Call (254) 602-5618 and we’ll tell you if your specific parcel is in the overlay before we quote.
Most of the time, yes, but the condition of the foundation, the electrical panel, and the sewer lateral determines whether it’s a $95,000 project or a $190,000 project. Upland’s 1920s through 1960s garages were built as storage and parking, not living space, so the city requires structural verification, a 200-amp panel upgrade, insulation, and a proper sewer connection before issuing the permit. We inspect all of that as part of our free estimate and give you a written price for the complete scope. Call (254) 602-5618 to schedule a site visit.
Yes. On oversized grove-era lots in North Upland, the city of Upland issues the ADU building permit, but San Bernardino County’s environmental health department has jurisdiction over septic systems and private wells. That means setbacks from your leach field and well head can dictate where the ADU goes and whether you need a septic system expansion. We coordinate both agencies before we finalize a quote so you’re not surprised by a county requirement mid-project. Call (254) 602-5618 and we’ll explain how it applies to your lot.
Santa Ana wind events funneling out of Cucamonga Canyon hit North Upland hard, which is why we spec Class A roofing and ember-resistant vents on foothill parcels even beyond what the fire code requires. The wind also drives air infiltration, so we pay close attention to air sealing and window ratings on the north and east exposures. A south-facing window wall looks great in renderings but turns an ADU into an oven in August. We design for the actual wind and sun patterns on your lot. Call (254) 602-5618 for a site-specific assessment.
Upland’s summer temperatures routinely pass 100°F at 1,200 to 1,500 feet elevation, and the low humidity means evaporative cooling won’t help. We install mini-split heat pump systems sized for Upland’s actual cooling load, not a generic California calculation, and we spec insulation levels that keep the unit livable through August without a $600 monthly electric bill. Every ADU we build in Upland includes a Title 24 energy report that confirms the design will actually perform here. Call (254) 602-5618 to discuss your project.
