Wellborn Home Additions & ADU: The San Francisco Owner’s Guide
If you’re planning a home addition or ADU in San Francisco and want Wellborn cabinetry in the build, plan on $53,100 – $153,400 for the full project, with cabinetry usually running $4,720 – $15,340 installed depending on series and how many linear feet you’re running. We stock, spec, and install Wellborn cabinets for additions and ADUs throughout San Francisco, and we can usually have your materials ordered and scheduled within two weeks. Most homeowners call us when they realize their existing Wellborn cabinets won’t survive the scope of an addition, or when they’re starting an ADU and need a cabinet package that matches the quality of the main house without blowing the budget.
Here’s the reality: a home addition or ADU is not a cabinet swap. It’s a structural project that happens to include cabinetry, and the Wellborn pieces need to be ordered, delivered, and installed on a schedule that doesn’t hold up framing, drywall, or electrical. We run the whole project, which means your Wellborn cabinets arrive when the walls are ready for them, not three weeks before or two weeks after.
Which Wellborn Models This Applies To
Wellborn runs three main cabinet lines: Essentials, Select, and Estate. Essentials is their entry line, Select is mid-grade with more door styles and finishes, and Estate is the full-custom program. For an ADU or addition in San Francisco, we typically spec Select for the kitchen and Essentials for the bathroom vanity and any kitchenette areas. The price gap between lines is real, and putting Estate cabinets in a rental ADU usually doesn’t pencil out.
Here’s the compatibility gotcha most homeowners learn the hard way: Wellborn cabinet box dimensions are not cut-to-order at the Essentials and Select tiers. They come in 3-inch increments, and you build the layout from standard widths. If your ADU kitchen is 11’4″ long, the design has to work around that increment. A designer who doesn’t know Wellborn will draw custom widths and then you’ll wait six weeks for a corrected order. Curtis Lane reviews every cabinetry takeoff against the actual framed wall dimensions before the order goes in.
On the OEM-versus-aftermarket question for Wellborn specifically: hinges, drawer glides, and shelf pins are all standard hardware, and we use the manufacturer’s hardware engineering specs for replacements. What’s not interchangeable is the finish. Wellborn’s Maple Cider stain is not the same as anyone else’s Maple Cider. If you need a door, drawer front, or panel matched, you order it from Wellborn with the original cabinet code. That’s the only way to get a match that doesn’t show in daylight.
Styles & brands we work with
Signs Your Wellborn Home Additions & ADU Is Failing
- The cabinet run is out of level after the foundation settled. San Francisco homes move, especially older ones in the Richmond and Sunset districts. Cabinets that were dead level in 2010 might be off an eighth of an inch now, and doors start binding at the corners. That’s a framing and shimming issue, not a cabinet defect.
- Drawer faces have hairline cracks near the handle. This is almost always moisture expansion. Fog-driven dampness finds its way into kitchens that don’t get enough ventilation, and the wood moves. Once a face cracks, it’s a replacement piece.
- Soft-close hinges no longer catch. The hinge mechanism wears out after about 8 – 10 years of daily use in a busy kitchen. Worse, a hinge that’s been adjusted too many times strips the mounting plate, and the door sags.
- The finish is flaking near the dishwasher or sink. That’s not a finish failure. That’s steam and moisture escaping from an unsealed gap and working behind the face. The cabinet needs sealing at the edge and the finish needs repair before the substrate swells.
- Upper cabinets have pulled away from the wall. This one is serious. In San Francisco’s older homes, installers sometimes anchor uppers into lath and plaster instead of the studs. When the cabinet starts to lean, it’s a mounting failure, and the cabinet has to come down and get re-hung properly.

AfterReplacement Cost & What’s Included
Installed Wellborn cabinet work in San Francisco runs $4,720 – $15,340 for a typical kitchen package, and $945 – $3,540 for a bath vanity. That includes the cabinets, hardware, delivery, install, and the written line-item quote before anything is ordered. What drives the range:
- Line and door style. Essentials shaker is the bottom of the range. Estate with a custom finish is the top.
- Linear feet. A 10-foot ADU kitchen is worlds apart from a 24-foot main-house kitchen.
- Existing wall condition. If the studs aren’t square, we fix the wall before the cabinets go up. That’s framing labor, and it’s in the quote.
- Hardware upgrades. Soft-close everything adds roughly 10 – 15% over standard hinges and glides.
Every Wellborn cabinet job we do is covered under the 365-Day Done Right Promise. If a door delaminates, a hinge fails, or a drawer binds inside that first year, we come back and fix it at no charge. The written guarantee is in your hand at close-out, with the scope documented and the final numbers matching the original quote.
DIY or Call Us?
You can measure your rough openings, count your linear feet, and write down which door style you currently have. That’s useful information when you call. You should not try to remove or re-level cabinets yourself in a home addition scenario. A loaded upper cabinet weighs 60 to 120 pounds, and when it comes off the wall, it comes down on you, your counters, or your floor. Beyond the safety issue, if you scratch one door panel during a DIY install attempt, you’re buying a replacement door from Wellborn, and lead times can run four to six weeks. Measuring is free to do. Mistakes aren’t. Call (831) 610-5598 and we’ll send someone out to take the real numbers.
FAQs
With proper install and average use, expect 20 – 30 years from Wellborn cabinet boxes in San Francisco’s climate. The hardware will need replacement around year 10, and the finish may need attention if the kitchen has chronic moisture issues. Fog-heavy neighborhoods like the Outer Sunset tend to age cabinet faces faster than the Mission or Noe Valley unless ventilation is handled.
Yes, in about 70% of cases we see in San Francisco. Hinges, glides, shelf pins, and drawer tracks are all swappable same-day if we have the hardware on the truck. Finish damage and cracked faces usually require ordering a new piece from Wellborn using your original cabinet code, which takes a few weeks.
For a kitchen-and-vanity package in an ADU, installation takes 2 – 3 working days once the cabinets arrive on site. Order lead time from Wellborn is usually 3 – 5 weeks for Select and Essentials. We order the cabinets the same week the rough framing passes inspection so materials arrive before the drywall is painted.
We stock standard Wellborn-compatible hinges, drawer glides, shelf pins, and mounting hardware, and we carry matching hardware in the most common finishes. Finish-matched doors, drawer fronts, and panels are order-only from Wellborn, made to your original cabinet code. We also support KraftMaid, Cambria, and Silestone hardware where the part is shared across manufacturers. Call (831) 610-5598 and tell us the part you’re after. If it’s on the truck, we’ll tell you over the phone.
