Interior Stair Railings in Alameda, CA
Custom interior stair railings and graspable handrails, from iron balusters to wood-topped balustrades, built to code for your remodel.
The railing you touch every day
Your interior stair railing is the one piece of metalwork in the house you actually put your hand on every day, so it has to be safe, comfortable, and good-looking. Whether you are remodeling a staircase, opening up a wall to a modern open-riser stair, or restoring the balustrade in a period home, we fabricate interior stair railings that fit the space and meet code. At Alameda Custom Railing we combine iron, steel, and wood into balustrades and graspable handrails tailored to your stair, then install them cleanly with minimal disruption.

What it is and who it's for
An interior stair railing is the handrail and guard along your staircase, landings, and open floor edges. It is for anyone remodeling or updating a home: replacing a dated or wobbly rail, opening a boxed-in stair, converting builder-grade pickets to iron balusters, or restoring a historic balustrade. It suits the East Bay's mix of housing perfectly, from graceful curved staircases in Alameda Victorians and Berkeley brown-shingles to straight runs in mid-century San Leandro homes. Because it is indoors, corrosion is not the concern; instead the focus shifts to fit, feel, graspability, and how the railing looks against your floors and walls.
This is detail work. The handrail profile, the baluster pattern, and the joinery where metal meets wood are what separate a custom stair railing from a hardware-store kit.
Materials and handrail profiles
We build interior stair railings in several directions:
- Iron baluster balustrades: forged or plain steel balusters, often with a stained wood top rail, for a classic or transitional look.
- All-metal modern rails: clean steel posts and a slim metal handrail for contemporary open-riser stairs.
- Wood-top handrails on metal: a warm graspable wood cap over a metal frame, a favorite for comfort underhand.
- Horizontal or cable infill for a modern interior look where code allows.
Graspability is code, not preference. A Type I handrail is a circular profile with a 1¼ inch to 2 inch outside diameter, or an equivalent graspable shape, so your hand can close around it. We build handrails to that spec, keep at least 1½ inches of clearance from the wall, and shape wood caps to feel right in the hand. The pattern and finish are yours to choose; the graspability is non-negotiable.
Code compliance
Interior stairs have their own rules. A graspable handrail must run 34 to 38 inches above the stair nosing, be continuous along the flight, and use a graspable profile, Type I circular 1¼ inch to 2 inch OD or equivalent, with at least 1½ inches of wall clearance. A guard is required where the floor or landing edge is more than 30 inches above the level below, generally at 42 inches tall, and baluster openings must not pass a 4-inch sphere (the stair-tread triangle allows up to 6 inches). Handrails must resist a 200-pound concentrated load, so anchoring into framing matters. These requirements come from the California Building Code and California Residential Code; confirm the current specifics with your local building department before finalizing a remodel.
How we build your railing
Consult & Measure
We measure the stair, discuss style and handrail feel, and plan around your remodel at no cost.
CAD & Shop Drawings

Engineering & Code Review
We confirm handrail height, graspability, guard height, and load requirements.
Shop Fabrication
We fabricate and weld the metalwork and prep any wood cap in the shop.
Finish & Install
We finish the metal, fit the railing to the stair, and anchor it into solid framing.
Inspect
We verify heights, spacing, and load, then pass final inspection.
Built for the East Bay
Interior railings do not fight salt air, but East Bay homes bring their own challenges. Alameda and Berkeley are full of Victorian, Edwardian, and brown-shingle houses with original balustrades worth restoring, and for designated historic homes the California Historical Building Code Section 8-504 can allow period-appropriate details that strict modern code would not. We match existing profiles and preserve character. In hillside Oakland and Berkeley homes along the Hayward Fault, interior stairs and split-level landings often need new guards, and we anchor handrails and posts firmly into the framing so they hold under load and movement. In mid-century San Leandro and Castro Valley homes, opening up a dated boxed stair to iron balusters or a modern metal rail is one of the most popular remodels we do.
Honest pricing
A typical interior stair railing, around 25 feet, generally runs $900 to $2,500, depending on material, baluster count, handrail profile, and whether a wood cap or historic match is involved. Curved stairs, dense forged balusters, and premium wood caps push higher, while a simple straight run of standard balusters sits lower. Removing an old railing, patching, and refinishing add labor, and permits for structural changes run $50 to $500. These are honest ranges, not a quote. The accurate number comes from a free on-site estimate where we see the actual stair.
| Scope | Typical range |
|---|---|
| Typical interior stair (~25 ft) | ~$900–$2,500 |
| Permits (structural changes) | $50–$500 |

Questions, Answered
What makes a handrail graspable under code?
A Type I handrail is a circular profile with a 1¼ inch to 2 inch outside diameter, or an equivalent graspable shape, so your hand can close around it. It must sit 34 to 38 inches above the stair nosing, run continuously, and keep at least 1½ inches of clearance from the wall. We build our stair railings to that standard.
Can you put a wood top on a metal stair railing?
Yes, and it is one of our most requested combinations. A shaped wood cap over an iron or steel frame is warm and comfortable underhand while the metal provides strength and the baluster look. We shape the wood to a graspable profile and join it cleanly to the metalwork.
Can you match the balustrade in my historic home?
Yes. Because we fabricate in-house, we can reproduce existing baluster and handrail patterns to restore a Victorian or Edwardian stair. For designated historic homes, the California Historical Building Code Section 8-504 can permit period-appropriate details, which we coordinate with your local building department.
Do I need a permit to replace an interior stair railing?
A straightforward like-for-like handrail swap often does not, but opening a stair, changing the guard, or any structural work usually does, with permits running $50 to $500. We review your specific project against local code and can pull the permit as part of the job.
How much does an interior stair railing cost?
A typical interior stair of about 25 feet generally runs $900 to $2,500, depending on material, baluster count, handrail profile, and any wood cap or historic match. Curved stairs and dense forged balusters cost more. We give an honest quote after a free on-site estimate.
