Why Benson ADU Sacramento Is Parkway’s Preferred Home Addition Contractor Company
Parkway isn’t Sacramento proper, and the difference matters when you’re pulling permits. Our crews work regularly in this unincorporated pocket of Sacramento County, so we know what county plan check expects before we submit anything. That means fewer rejected plans and fewer stalled projects. Troy Eastman leads our Parkway work, and he’s the person who reviews your contract line by line before you sign, so you’re never handed a number that shifts once the crew shows up.
Homeowners in Parkway tell us the same thing: they wanted a contractor who’d answer the phone and show up when promised. We staff a live person around the clock, and every technician who steps onto your Parkway property is background-checked and in uniform. You’ll know exactly who’s at your door. Our Parkway customers also get the 365-Day Done Right Promise in writing: if something isn’t right within a full year, we make it right at no charge.
Second Story Addition Contractor in Parkway
A second story addition in Parkway gives you square footage without sacrificing yard space, which matters on the generous but not infinite lots common to this area. As a Second Story Addition Contractor in Parkway, we handle the structural engineering, floor system, staircase placement, and roof tie-in that a project like this demands. Parkway homes from the 1950s and 1960s often have solid stick framing that can carry a second floor, but the foundation needs a structural review first, and the existing first-floor walls may need shear reinforcement to meet current county code.
Second story additions in Parkway typically run $220 – $380 per square foot, with a full two-bedroom upper level commonly landing between $150,000 and $260,000. The range depends on whether you’re adding a bathroom upstairs, how much of the roof has to come off, and what the county requires for stair width and egress windows. We include the structural engineering and the permit set in that price.
What to expect when we open your roof
On a 1950s home off Park Ridge Drive, our crew opened a rear bedroom wall and found degraded wood framing behind the stucco and a brittle 100-amp panel feeding the whole house. We had already written an electrical upgrade allowance into the contract, so when we found undersized circuits and a cast iron sewer lateral that couldn’t support the new bathroom, we priced both in writing and got approval before touching anything further. That’s how every Parkway second story starts: inspection, then written numbers, then work.
Setbacks and height limits above the first floor
Because Parkway is unincorporated Sacramento County, Home Addition Contractor projects must meet county setback and lot-coverage rules that can be more restrictive than those of the City of Sacramento only blocks away, a distinction many homeowners discover only when their plans are rejected. A second story also triggers a height limit review, and on some Parkway lots that means adjusting the roof pitch or stepping the upper floor back from the property line. We check all of that before you spend a dollar on plans.
Garage Addition Contractors in Parkway
A garage addition in Parkway usually means one of two things: converting an existing attached or detached garage into living space, or building a new garage with a room above it. As Garage Addition Contractors in Parkway, we’ve done both on the older single-family lots that dominate this area. Garage conversions in Parkway typically run $80,000 to $140,000 when the slab and framing are sound, while a new detached garage with living space above runs $120,000 to $200,000 depending on square footage and whether you add a bathroom.
Many Parkway garages from the 1940s through 1970s were never insulated and sit on slabs without vapor barriers, which means they’ll fail a county inspection as living space unless we address moisture and insulation. We factor that into the written estimate from the start, so you’re not blindsided at rough inspection.
Slab, sewer, and power checks come first
Before we quote a garage conversion, we camera the sewer lateral and check the electrical service. On older Parkway lots, a collapsed clay pipe or a 100-amp panel that’s already maxed out will add $8,000 to $25,000 to the project, depending on the repair. We’d rather tell you that on day one than let it surface after the slab is cut.
Detached garage ADU option
If you’re weighing a garage addition against an ADU Builders in Parkway option, we can show you what works under Parkway’s county lot-coverage rules. The math on a new detached structure with living space often comes out close to an ADU once you count plumbing and electrical, and an ADU gives you rental income flexibility that a plain garage won’t. We’ll price both options in writing so you can decide with real numbers.
Trusted Brands We Service in Parkway
We build with materials Parkway homeowners can research themselves. For exterior cladding that holds up to Sacramento County’s triple-digit summers and wet winters, we often specify James Hardie fiber cement siding and trim. For panels and envelope systems, we can price Abodu, Cover, and Dvele options so you get factory-built precision with site-built flexibility. Our Parkway customers get access to these brands without chasing down a single product rep. We order, schedule, and warranty the whole package.
Common Home Addition Contractor Problems We See in Parkway Homes
- Aging sewer laterals on 1940s – 1970s lots. Starting without a sewer lateral camera inspection is the single most expensive mistake we see on Parkway additions. A collapsed clay pipe found after the slab is cut can add $10,000 to $20,000 and two weeks of delay.
- Original 100-amp electrical panels. Many Parkway homes still run on service that can’t support new circuits. Leaving the panel untouched until final inspection means a failed inspection and an unplanned upgrade. We price the panel replacement into the contract up front.
- Rotted framing and failed waterproofing behind stucco. Parkway homes from the post-war era often have wood framing that’s been wet for decades. Once walls are open, we regularly find sections that need replacement before new work can be tied in.
- Insufficient roof ventilation for county summers. Parkway sees triple-digit days every summer, and an addition with poor attic ventilation turns into an oven. We design for ridge and soffit venting from the start, and we often pair it with ductless mini-splits for cooling without ductwork.

FAQs About Home Addition Contractor in Parkway
Parkway falls under Sacramento County’s Building Department, not the City of Sacramento, so your addition must meet county setback and lot-coverage rules that can be more restrictive on the same size lot. The practical impact is often a smaller allowable footprint or a higher rear-yard setback, which can force a redesign if plans were drawn assuming city rules. We verify the exact parcel constraints before we draw anything, so your plan gets through plan check the first time. Call (279) 254-1808 and we’ll check your specific lot.
In most Parkway homes built before the 1980s, yes. A 100-amp panel can’t support the added circuits, lighting, and HVAC load that a habitable addition requires, and county inspectors will fail final if the service isn’t upgraded. A standard 200-amp panel replacement with grounding typically runs $4,000 to $7,000 on Parkway properties, and we write that allowance into your contract before work starts. For a precise number on your home, call (279) 254-1808 for a free estimate.
We inspect first, before demolition, so most surprises are already known before a single wall is open. When we do find rotted framing or failed waterproofing that wasn’t visible from the outside, we stop work, document it with photos, and hand you a written price for the repair before we proceed. You approve the number in writing, and nothing gets added to the job without your sign-off. That process is part of our 365-Day Done Right Promise, and it’s stamped on every Parkway contract.
On lots with homes built from the 1940s through the 1970s, it’s common. Parkway has a high concentration of older cast iron and clay sewer laterals, and adding a bathroom or kitchen often means the existing lateral can’t handle the added flow, or it fails a camera inspection outright. A lateral replacement in Parkway typically runs $8,000 to $18,000 depending on depth, length, and whether a sidewalk cut is needed. We camera the lateral before we quote so you know on day one, not after the slab is cut. Call (279) 254-1808 to get yours inspected.
We design Parkway additions for Sacramento County’s climate, not a northern California template. That means ridge and soffit venting matched to the new roof assembly, R-38 or better ceiling insulation, and in most cases a ductless mini-split for cooling instead of extending old ductwork that was never sized for the added square footage. Proper ventilation isn’t optional here; a poorly vented Parkway attic hits 140°F and makes the rooms below it miserable. Your estimate includes the full insulation and ventilation scope in writing.
