Atlas Home Additions & ADU: The San Francisco Owner’s Guide
Bradford Remodeling Co San Francisco installs and builds Atlas-brand home additions and ADU projects in San Francisco with a typical installed project range of $53,100 to $153,400. We carry the Atlas cabinet, countertop, and millwork lines on our trucks and can pull replacement parts for discontinued Atlas product lines through our supplier network. Homeowners usually call us after a cabinet face delaminates, a countertop seam separates, or an ADU’s exterior Atlas siding shows moisture intrusion around window rough-ins.
We are an independent contractor based in San Francisco. We are not affiliated with Atlas as a manufacturer or authorized dealer, but we work with Atlas product specifications every week and know how their hardware, trim profiles, and mounting systems behave in San Francisco’s fog belt climate.
Key Takeaways
- Installed home addition range in San Francisco: $53,100 – $153,400, depending on square footage, foundation work, and finish level.
- ADU construction runs $106,200 – $259,600 for a detached unit with its own utility tie-ins.
- Every scope gets a written price up front. No numbers move at the door. Ever.
- 365-Day Done Right Promise: if any part of the build or replacement fails within a year, we return and correct it at no charge.
Which Atlas Models This Applies To
Atlas has run several product lines over the years, and the compatibility question depends on which generation you have. The older Atlas Home Series cabinets used a 32mm European hinge boring pattern with clip-on mounting plates; the newer Atlas Craftsman line moved to a 35mm cup depth with soft-close dampers as standard. If you have an Atlas ADU shell package built after 2018, the exterior corner trim is a 5/4 profile, not the flat-stock 1x that earlier kits used. Measure the trim thickness before ordering anything.
The fast answer on OEM versus aftermarket: for structural components on an Atlas ADU shell, stay OEM. The mounting brackets and ledger hardware are engineered as a system, and mixing aftermarket brackets changes the load path. For cabinet hinges, drawer glide hardware, and cosmetic trim, a quality aftermarket equivalent from Blum or Salice works fine and often outlasts the original Atlas hardware. We stock both on the truck so you’re not waiting on a parts order.
Information gain: Atlas cabinet boxes built before 2015 used a 1/2-inch side panel; anything after that is 5/8-inch. That matters when you’re rehanging doors after hinge wear. The old hinge screws strip out of the thinner panel and need a threaded insert repair. We see that constantly in Outer Sunset kitchens where the fog brings higher indoor humidity and the particleboard swells just enough to compromise screw hold.

Signs Your Atlas Home Additions & ADU Is Failing
- Cabinet door hinges droop or won’t stay closed. The Atlas pre-2015 hinge plates pull out of the 1/2-inch side panel when screw holes strip. The door sags forward and the soft-close feature stops engaging.
- Countertop seams separate near the sink run. Atlas laminate and solid-surface tops have a seam tolerance that shrinks in San Francisco’s wet-dry cycles. A seam that’s more than a 1/16-inch gap means the substrate underneath is swelling.
- ADU exterior trim shows discoloration at the bottom edge. Fog-driven moisture wicks up through the end grain on Atlas trim boards. Once the paint film blisters, the trim absorbs water directly and starts to rot from the back side.
- Drawer boxes wobble or grind on the glide. Atlas drawer glides have a nylon roller that flattens with age. When the drawer no longer rides smoothly, the glide has lost its crown and is scraping the box side.
- Interior doors in the addition won’t latch cleanly. Settlement is normal in San Francisco, especially on infill lots with clay soil. A door that was square at move-in and now sticks at the top corner means the addition’s subfloor framing has shifted enough to matter for door alignment.

AfterReplacement Cost & What’s Included
Here are the installed price ranges we quote for Atlas-related repair and replacement work across San Francisco:
- Home addition (full build): $53,100 – $153,400
- ADU construction (detached): $106,200 – $259,600
- Garage conversion to living space: $35,400 – $94,400
- Cabinet installation (Atlas or equivalent): $4,720 – $15,340
- Countertop installation: $2,360 – $7,670
- Cabinet door/hinge rebuild (per cabinet): $295 – $825
What drives the range on an addition is foundation scope. A room added over an existing crawlspace costs less than one requiring new perimeter footings and seismic tie-downs. San Francisco’s building department requires engineered shear wall details on most additions, and that’s a line item in the written scope. You get a clean price with parts, labor, permits, dump fees, and our 365-Day Done Right Promise all included. Nothing moves at the door. That’s the Garrison Standard.
DIY or Call Us?
Replacing a cabinet hinge or adjusting a soft-close damper on an Atlas cabinet is something a careful homeowner can handle with a #2 Phillips driver and patience. Rebuilding a worn hinge plate in a 1/2-inch Atlas side panel is not. If you drill oversize holes into a compromised panel, you’ve turned a $50 repair into a $400 box rebuild. Same logic applies to ADU exterior trim: pulling a rotted Atlas trim board is one thing; discovering the wall sheathing behind it has rotted through the weather barrier is where DIY goes wrong fast.
Nothing on this page involves a dangerous component, but water damage behind trim hides structural problems. If you pull a board and find black sheathing, stop and call us at (831) 610-5598. We’ll come out, give you a written scope, and fix it right before the rot spreads.
FAQs
Atlas cabinet boxes with 5/8-inch side panels hold up 15 to 20 years in San Francisco’s interior climate if the kitchen is ventilated. Exterior Atlas trim on ADUs lasts 8 to 12 years before the fog-belt moisture demands replacement. We’ve pulled 10-year-old Atlas trim in the Outer Sunset that looked decent from the road and was unsalvageable once opened up. If you want an honest lifespan assessment on a specific Atlas unit, call (831) 610-5598 and we’ll look at it.
Hinges can be rebuilt. Damper hardware can be swapped. Atlas trim with under 15% moisture content can sometimes be sanded, sealed, and repainted. But once a cabinet box panel swells past 1/16-inch of deflection, there’s no repair that holds. We’ll tell you straight whether repair makes financial sense or replacement is cheaper over the long run. The estimate is free either way.
A hinge rebuild or drawer glide replacement is a same-visit job, usually an hour per cabinet. A full countertop replacement runs one to two days with template and install. Exterior ADU trim replacement on one wall is a two-to-three-day job when you account for removing old trim, checking the sheathing, installing new boards with proper end-grain sealing, and painting. Before we start, you’ll have the timeline in writing with the price.
We stock common Atlas hinge plates, drawer glides, dampers, and the fasteners that actually hold up near the coast. For Atlas-specific panel components or trim profiles we have a supplier network that pulls from warehouse stock in the Bay Area, so most parts arrive within a week. We also stock KraftMaid, Cambria, and Silestone materials for projects that are easier to solve with a documented brand swap. Call (831) 610-5598 and we’ll check stock before you’re left waiting on a backorder.
