Why Lodgewick ADU Sacramento Is Roseville’s Preferred Garage Conversion Contractor Company
We’re the Garage Conversion Contractor team homeowners in Roseville call after a bad experience with someone else. Russ Delmar leads our operation, and he’s built our reputation on something simple: we write the price down before work starts, and we put the 365-Day Done Right Promise in writing on every single project. If it’s not done right, we come back and make it right. That’s not a slogan. It’s the Kingswell Guarantee, and it’s been our operating rule since 2010.
Roseville homeowners tell us the same story over and over. A contractor gave a verbal estimate, then the price changed at the door. A crew showed up two days late with no call. A sub walked off mid-job. We built Lodgewick ADU Sacramento specifically so that never happens to you. A live person answers our phone 24 hours a day, seven days a week. When you call about your Roseville garage conversion, you get a human who knows your project, not a voicemail loop.
We’re also honest about what your garage actually needs. In Roseville’s older tracts, that often means telling you the panel needs upgrading before we touch a wall. Most contractors won’t mention it until the inspector stops the job. We mention it in the first conversation, because we’ve done this enough to know where the surprises hide.
Garage to Bedroom Conversion in Roseville
A garage to bedroom conversion in Roseville turns your existing attached or detached garage into a permitted sleeping room, usually without a full kitchen, and it’s the most budget-conscious way to add living space without building new square footage. In Roseville, this job typically runs $35,000 to $65,000 depending on whether we’re working with an attached garage in a 1990s tract home or a detached structure with older framing. The price includes insulation, drywall, flooring, egress windows, electrical, and bringing the room up to California Building Code for a legal bedroom.
Attached Garage Bedroom Conversions
Most Roseville homes built between 1970 and 1995 have attached two-car garages with a shared wall to the house. That shared wall usually works in your favor. The framing is already there, the roofline is established, and we can tie into the home’s existing foundation with minimal disruption. But you’ll need to address the slab, because pre-1990 garages in Roseville rarely have a moisture barrier, and you can’t put flooring over a slab that wicks groundwater.
Detached Garage Bedroom Conversions
A detached garage gives you more design freedom, and in Roseville’s 7,000 to 10,000 square foot lots, there’s usually room to work. We see a lot of these in the Foothill Junction area and along Cirby Way. The tradeoff is running utilities. Trenching electrical and plumbing from the main house to a detached structure adds $8,000 to $15,000 on average, and if the existing structure sits close to a rear property line, you may need a variance before we can pull permits.
Garage Conversion ADU in Roseville
A garage conversion ADU in Roseville takes that same garage and turns it into a fully self-contained accessory dwelling unit, with its own kitchen, bathroom, separate entrance, and usually its own utility service. This is the highest-value conversion for Roseville homeowners, because the city has worked hard to streamline ADU permitting, and a permitted unit can generate rental income or house family. Expect to pay $90,000 to $160,000 depending on the condition of the garage, the panel situation, and whether we’re doing a full gut or a partial refinish.
Attached Garage ADUs on Pre-1990 Lots
Here’s where Roseville gets specific. Homes built before 1990 in neighborhoods like Cherry Glen and Cirby Ranch almost always have original 100-amp electrical panels sized for a single household. Add a separate dwelling unit with its own kitchen, and Roseville Electric’s service standards will require a panel upgrade or a separate service drop. That’s an extra $3,500 to $8,000 most homeowners don’t see coming. We tell you about it on day one, because we’ve watched too many Roseville projects hit a stop-work order over this exact issue.
Detached Garage ADUs in Rear Yards
Detached garage ADUs in Roseville’s rear yards work well because lots are generous and the city’s zoning code favors rear-yard accessory units. But setbacks are the quiet killer. If your garage sits within 5 feet of a side property line, the city may require a setback review, and corner lots have different front-yard rules than interior lots. We map this before quoting, so the written price we give you actually reflects what the city will approve.
Trusted Brands We Service in Roseville
We work hands-on with the prefab and panelized systems that fit Roseville’s climate and lot patterns. Dvele and Mighty Buildings are two we recommend regularly here, because their wall assemblies handle Placer County’s hot, dry summers with far better insulation values than stick framing, and that matters when temperatures push past 100°F in July. For homeowners who want a faster build, we’ve also done strong work with Boxabl units, though permitting a Boxabl in Roseville requires careful coordination with the city’s design review standards. We don’t just sell a brand. We match the system to your lot, your timeline, and your budget, then we stand behind the install with the same 365-Day Done Right Promise we put on every project.
Common Garage Conversion Contractor Problems We See in Roseville Homes
- Original 100-amp panels that can’t carry a second dwelling unit. Roseville Electric’s inspectors flag this on nearly every pre-1990 conversion, and it stops work until the homeowner pays for an upgrade they weren’t planning on.
- Slabs without perimeter insulation or moisture barriers. Most Roseville garages built before 1990 sit on a 3.5-inch slab with no vapor barrier. You can’t legally finish that space without cutting, removing, and re-pouring a thickened-edge slab, which adds real money fast.
- Side-yard setback violations on corner lots. Roseville’s zoning applies different front-yard setback rules to corner lots than interior lots. A garage that looks fine on paper may be too close to the side street once the city reviews it.
- Stop-work orders from unpermitted panel work. Too many homeowners hire a handyman who says the panel is fine, then Roseville Electric’s inspector disagrees. We pull permits, coordinate with the city, and pass inspection before drywall ever goes up.

FAQs About Garage Conversion Contractor in Roseville
If your home was built before 1990 and still has its original 100-amp panel, yes, you almost certainly need a panel upgrade or a separate service drop. Roseville Electric’s service standards require a separate dwelling unit to have adequate capacity, and a 100-amp panel sized for one household can’t legally carry a second kitchen. Budget $3,500 to $8,000 for this. We confirm panel capacity before quoting, so the price we write down already accounts for it. Call (279) 256-1973 and we’ll check your panel situation directly.
It depends on your lot type. Roseville treats corner lots differently than interior lots for front-yard setbacks, and a garage that sits 4 feet from a side property line may trigger a setback review. In some cases the city grants relief; in others, you’ll need a variance hearing. We coordinate directly with Roseville’s building department before quoting so you know what’s approvable. On a Cherry Glen cul-de-sac recently, we converted a 1978 garage that sat 4 feet from the side lot line only because we applied for setback relief up front. The city approved it, but it added time to the permit phase.
You can still convert it, but you cannot legally finish over that slab as-is. Pre-1990 Roseville garages typically have a 3.5-inch slab with no vapor barrier and no perimeter insulation. Building code requires a moisture barrier and proper insulation before you can install drywall and flooring. That means saw-cutting, removing, and re-pouring a thickened-edge slab, which runs $6,000 to $14,000. We include this in the written quote when we see it, not after the fact. Call (279) 256-1973 for a site visit and we’ll tell you exactly what your slab needs.
Roseville wants ADUs to look like they belong in the neighborhood, so the city enforces design standards around rooflines, siding materials, window placement, and exterior colors. A garage conversion that changes the street-facing elevation may need to match the primary home’s architecture. In practice, that means we match stucco or siding, keep window proportions consistent, and often use James Hardie products because they hold up in Roseville’s summer heat without fading. We handle design review as part of the permit package so you’re not guessing what the city will accept.
Roseville does not require a separate electric meter for an ADU, but many homeowners choose one anyway because it makes rental billing cleaner. Water and sewer are trickier. If your garage ADU is detached, you may need a separate water service lateral and sewer connection, which means trenching across the yard and coordinating with Roseville’s utility department. We scope this during the estimate because it changes the price materially, usually by $5,000 to $12,000 depending on distance from the main line. Call (279) 256-1973 and we’ll map your utilities before we give you a number.
