Adding an accessory dwelling unit (ADU, a separate living space with its own kitchen, bath, and entrance) to a La Riviera lot is one of the smartest moves a homeowner here can make. The large ranch-style lots in unincorporated Sacramento County give you room to build, and the county’s rules are friendlier than the city of Sacramento’s. Most La Riviera ADU projects run from $180,000 for a compact studio to $420,000 for a larger two-bedroom detached unit. Call Lodgewick ADU Sacramento at (279) 256-1973 and we’ll give you a written price before any work begins.
We know La Riviera’s housing stock: 1950s and 1960s single-story ranchers on slab foundations, wide side yards, mature fruit trees, and clay-heavy soil that holds water in winter. That knowledge changes how we quote, design, and build. Russ Delmar leads our team, and every project runs on The Kingswell Guarantee: a written price first, a real arrival window, a clean job site, and a written guarantee on the finished work.
Why Lodgewick ADU Sacramento Is La Riviera’s Preferred ADU Builders Company
La Riviera homeowners don’t need a contractor who treats their street like just another map pin. They need someone who knows that a 1962 rancher off La Riviera Drive likely has cloth-insulated wiring behind the drywall, and that the flat clay soil means a French drain isn’t optional. That’s the kind of local knowledge that keeps a budget from blowing up once walls are opened. Our ADU Builders team has walked through enough La Riviera backyards to know where the setbacks fall, where the sun hits hardest in July, and which side of the lot drains toward the house.
We answer our own phones, 24/7. When a La Riviera homeowner calls with a question about their build or their written guarantee, a live human picks up. Not a voicemail, not a chatbot. Russ Delmar reviews every La Riviera project scope personally before we send out a written price. And if the work isn’t right, our 365-Day Done Right Promise means we come back and make it right at no charge. That promise is in writing on every project, before the first nail goes in.
ADU Contractor in La Riviera
An ADU Contractor in La Riviera manages the full build, from demolition through final inspection. On a 1960s ranch, that’s not a simple framing job. It means opening walls and finding what’s been hiding for sixty years: two-wire electrical, undersized headers, rotted sill plates from sprinkler overspray, and sometimes asbestos in old flooring or drywall compound. A full detached ADU build in La Riviera typically runs $220,000 to $380,000, depending on size and site conditions. A garage conversion into an ADU runs $140,000 to $240,000.
What a La Riviera ADU Permit Actually Triggers
Once you pull a permit in unincorporated Sacramento County, the county inspector checks more than the new structure. They look at what the new unit touches: the existing electrical panel, the water heater capacity, smoke and carbon monoxide coverage, and structural connections. If your 1960s panel is a 100-amp Zinsco or Federal Pacific, the inspector will likely require an upgrade to 200 amps before the ADU can pass. We write allowances for those exact upgrades into our contract so the surprise is already priced and approved.
Inspection-First Building, Not Guesswork
We don’t quote a La Riviera ADU blind. Before we give you a written price, we open the relevant walls, check the slab with a level, test the soil for drainage and compaction, and order asbestos testing if we’re touching original materials. Then the price we hand you covers what we actually found, not what we assumed. That’s the difference between a project that stays on budget and one that spirals when the inspector shows up.
ADU Design in La Riviera
ADU Design in La Riviera means working with what’s actually on the lot: a mature orange tree in the back corner, a slab that’s settled a half-inch over sixty years, and a side yard that’s wider than the house footprint itself. Design work for a detached ADU here runs $6,000 to $15,000 depending on complexity and whether we’re working with a prefab unit or a fully custom build. That design fee rolls into your total project price when we build.
Keeping Your Trees, Building Your Unit
La Riviera’s old citrus trees aren’t just landscaping. They’re shade, privacy, and part of what makes these lots feel like home. We design ADU placement around root zones and canopy spread, often tucking the unit behind a mature tree instead of cutting it down. That means slab-on-grade with pier and beam adjustments in root zones, and foundation depths specified by a soils engineer before we place any concrete.
Designing for 100-Degree Summers and Winter Rain
A La Riviera ADU needs to stay cool through July without costing a fortune, and it needs to stay dry through February. We spec mini-split heat pumps as standard for ADUs here, sized for a space that will hit 100°F outside in August. And we design drainage from the start: roof runoff directed into French drains, grading sloped away from both the new unit and the existing house, and a perimeter drain if the lot sits low on the street.
Trusted Brands We Service in La Riviera
We work with established ADU manufacturers and materials suppliers that hold up under Sacramento’s climate, including Abodu, Cover, and Mighty Buildings. For La Riviera homeowners who want a faster path to occupancy, a prefab unit from Abodu or Mighty Buildings can cut site time significantly. For custom builds, we spec James Hardie siding and quiet, high-efficiency mini-split systems that keep La Riviera ADUs cool without tripping the main panel. We match the brand to your lot, your budget, and your timeline during design, before you’re locked into anything.
Common ADU Builders Problems We See in La Riviera Homes
- Cloth-insulated wiring behind 1960s drywall. Two-wire cloth cable doesn’t have a ground, and once a permit inspector sees it, a panel upgrade and rewire of the affected circuits is usually mandatory. We test for it before we quote, so the price already includes it.
- Rotted sill plates from decades of sprinkler overspray. The bottom plate of a framed wall sitting next to a lawn line is often soft and compromised. We replace it with pressure-treated lumber and fix the drainage that caused it, so the rot doesn’t return.
- Unflat 1960s slabs that crack under new footings. Older slabs settle unevenly on La Riviera’s clay-heavy soil, especially after wet winters. We check the slab with a laser level and run a soils report before placing the new unit’s footings, because a cracked slab is a structural fault, not a cosmetic one.
- Water pooling at the base of the new ADU after a wet winter. Standard gutters won’t move water away from a flat lot. We install French drains and grade the surrounding soil so rain runs away from the structure, not into the framing.

FAQs About ADU Builders in La Riviera
Most 1960s La Riviera homes have a 100-amp electrical panel, two-wire cloth-insulated circuits, and no exterior wall insulation. A permit for an ADU almost always triggers a panel upgrade to 200 amps, a rewire of any circuit the new unit ties into, and GFCI/AFCI protection on affected outlets. We write those upgrades into the written allowance in your contract before we start, so the permit inspection doesn’t turn into an unbudgeted expense. Call (279) 256-1973 for a site walk-through and we’ll tell you exactly what your house will trigger.
We test before we touch anything. Older sheet vinyl flooring, drywall compound, and some insulation in 1950s and 1960s homes can contain asbestos. We pull samples and send them to a certified lab before demolition begins. If the results come back positive, we bring in a licensed abatement crew, and that cost is already accounted for in your written price. No surprises, no workarounds.
Yes, in most cases you can keep the tree and build the unit. We design the ADU footprint around the root zone rather than cutting into it, which often means moving the unit a few feet toward the lot line or adjusting the foundation to a pier-and-beam detail near the roots. A mature La Riviera orange or lemon tree provides real shade and privacy for the new unit, and it’s almost always worth working around. We’ll show you the tree line on the site plan before you approve anything.
La Riviera’s clay-heavy soil drains slowly, and the flat lots don’t give water anywhere to go. A French drain along the ADU’s foundation moves roof runoff and groundwater away from the slab, preventing rot, mold, and cracking. And a mini-split heat pump is the most efficient way to cool a small space through Sacramento summers and heat it through the cool, wet winters. These aren’t upgrades; they’re baseline requirements for a unit that lasts.
We open the relevant walls, check the slab, test the soil, and run asbestos sampling before we hand you a written price. Then the number on the page is the number you pay, because the contract has written allowances for the hidden conditions we found and anything similar we might find during the build. Any change order is priced and approved in writing before our crew touches it. That’s how a La Riviera ADU stays on budget and on schedule. Call (279) 256-1973 to start the process with a free inspection.
