When Folsom homeowners ask what a home addition actually costs, they want a real number, not a sales pitch. A room addition in Folsom typically runs $180,000 to $420,000 depending on whether you’re building a single bump-out bathroom or a full second story. We’re Lodgewick ADU Sacramento, and we bring written pricing, a written guarantee, and crews who know Folsom’s HOAs and building department better than most. If you’re weighing a home addition, call (279) 256-1973 and we’ll give you a straight answer.
Why Lodgewick ADU Sacramento Is Folsom’s Preferred Home Addition Contractor Company
Our Home Addition Contractor team has spent years working inside Folsom’s master-planned communities and historic district, which means we know the difference between what works in Folsom Ranch versus what’s approvable near Sutter Street. Russ Delmar leads every project with a simple rule: the price we quote in writing is the price you pay. No change orders at the door, no vague allowances, no surprises. That’s the commitment Folsom homeowners deserve after being burned by contractors who disappear mid-project.
We put The Kingswell Guarantee on every job: a written price before work starts, a defined arrival window, a clean job site, and a written guarantee on the finished work. If something isn’t right within 365 days, we come back and make it right. That’s why Folsom clients from Parkway to Folsom Lake call us first. Our local reputation rests on showing up when we say we will and answering our phones with a real person, 24/7.
Garage Addition Contractors in Folsom
Garage Addition Contractors in Folsom handle two distinct jobs: expanding an existing attached garage to gain storage or workshop space, or converting part of a garage footprint into heated living area while preserving a bay or two for vehicles. In neighborhoods like Empire Ranch and Broadstone, where HOA rules govern rooflines and front elevations, a garage addition must match the original architecture. That’s non-negotiable with the associations here. A garage addition in Folsom typically costs $90,000 to $190,000, with the higher end reflecting engineered foundations and HVAC extension work.
Attached Garage Expansions
Some Folsom lots have side yards wide enough to push a garage out by 6 to 10 feet. We handle the structural tie-in, roof matching, and HOA architectural review package. The written price covers permits, engineering, and the matching shingle or tile roof profile.
Garage-Plus-Living Conversions
When homeowners need a home office or guest suite without losing car storage, we frame a partial conversion that keeps one bay intact. This lets parents in American River Canyon North add a private workspace while still parking their truck inside. Budget $130,000 to $220,000 for this scope.
Bathroom Addition Contractor in Folsom
A Bathroom Addition Contractor in Folsom most often works on two scenarios: adding a full bath off a primary suite in older ranch homes near the historic district, or adding a powder room near a home office in newer subdivisions like Willow Creek. Older Folsom ranch homes from the 1950s and 60s often have cast-iron drain lines that need replacement before new plumbing can tie in, and our crews account for that in the written quote rather than “discovering” it later. A bathroom addition in Folsom generally runs $55,000 to $110,000 depending on finish level and whether we’re extending plumbing through a slab or crawl space.
Spa-Style Primary Bath Additions
We’ve built heated-floor primary baths in Folsom Point and Los Cerros where homeowners wanted a true retreat rather than another cramped hall bath. These jobs run $90,000 to $140,000 and include glass enclosures, custom vanities, and moisture-rated ventilation suited to Folsom’s hot summer stretches.
Powder Room and Hall Bath Additions
For homes where a guest bath means not sharing with three kids, a compact hall bath addition runs $55,000 to $80,000. We handle the venting, waterproofing, and tile work with materials that resist cracking when temperatures swing from 105°F in August to freezing on January mornings.
Trusted Brands We Service in Folsom
Our crews work regularly with prefab and panelized systems from Cover, Dvele, and Boxabl, which keeps Folsom projects moving faster than fully stick-built additions, and we also offer Cover repair in Folsom when existing structures need attention. We match each system to the lot and the HOA’s design guidelines, not the other way around. Because we order from these manufacturers frequently for Folsom jobs, lead times stay shorter and material costs stay predictable. James Hardie siding and trim products factor into most of our Folsom additions since they hold up to Folsom’s dry heat without warping or fading.
Common Home Addition Contractor Problems We See in Folsom Homes
- HOA rejection without a proper architectural package. Empire Ranch, Broadstone, and Parkway all have design review committees that want elevations, material boards, and roof details in a specific format. Contractors unfamiliar with Folsom get bounced back, adding months to the timeline. We submit complete packages the first time.
- Cooling loads underestimated for Folsom summers. A new room with west-facing windows in a neighborhood like Folsom Point will bake in July and August. We size HVAC extensions for actual Folsom heat, not a generic California average.
- Historic district constraints near Sutter Street. Homes in and around Folsom’s historic district face additional design review before any addition moves forward. We know which details fly and which trigger resubmittal.
- Cast-iron drain failures in older ranch homes. Homes built in the 1950s and 60s near Lake Natoma often need drain line replacement as part of any bathroom or kitchen addition. A contractor who quotes without checking the existing lines will hit you with a change order later. We inspect first and quote accordingly.
Pricing for Home Addition Contractor in Folsom, CA
