Multifamily Railings in San Ramon & the Tri-Valley

Multifamily railings for SB 721 buildings in San Ramon

Multifamily railings in San Ramon and the Tri-Valley have moved from a maintenance item to a compliance item, because the first SB 721 inspection deadline has come and gone. Owners who had their balconies inspected are now holding reports that flag loose posts, rotted wood rails, rusted post bases and guards that sit below today's height. Owners who have not inspected yet are behind.

We are the shop that turns the railing items on that report into finished, permitted work. We fabricate guardrails and handrails in our own shop, build every building on a property to one consistent spec, and install in phases so residents keep living there while the work happens. We do not perform the SB 721 inspection itself. We work from the inspector's findings and close them out.

If you have a report on your desk, call (925) 438-6219. We will walk the property with it and give you a scoped, written plan.

What SB 721 asks of apartment guardrails

SB 721, codified in Health and Safety Code section 17973, applies to buildings with three or more multifamily rental units. It targets exterior elevated elements more than six feet above grade that are exposed to weather: balconies, decks, stairways, walkways and landings, along with the guardrails and handrails attached to them. A qualified licensed professional inspects a sample of at least 15 percent of each type of element and reports on its condition.

• Deadline: the first inspection was originally due January 1, 2025. AB 2579 extended it to January 1, 2026. That date has passed, so any building without a completed inspection is late.
• Cycle: after the first inspection, the elements are inspected again every six years.
• San Ramon: the city publishes a California Balcony Laws page. Conditions that pose an immediate hazard go to the Chief Building Official within 15 days, and the owner must apply for a repair permit within 120 days.

Other Tri-Valley cities and Contra Costa County run their own enforcement, so confirm local timelines with the building department. Our SB 721 guide for Tri-Valley rentals walks through the statute in more detail, and our railing repair and SB 721 page covers smaller fixes.

Where the Tri-Valley's apartment balconies are

Multifamily housing is not spread evenly across the valley. Census data shows how much of each city's housing sits in larger buildings, which is a fair proxy for where SB 721 work concentrates.

Source: American Community Survey 2020–2024 estimates. Keep in mind that SB 721 starts at three units, so duplex-plus and small fourplex owners are covered too even though they fall outside the 5+ column. In San Ramon the larger complexes cluster around Bishop Ranch and Dougherty Valley; in Dublin they sit near the BART stations; in Walnut Creek they run from downtown out along the major corridors.

One railing spec across every building

A property that patches balcony by balcony ends up with three post styles, two colors and a guard height that changes from one stack to the next. We write one spec for the whole property and build to it everywhere:

• Guards at 42 inches wherever the walking surface is more than 30 inches above grade.
• Openings that will not pass a 4-inch sphere, with the 6-inch allowance only at the stair tread triangle.
• Stair handrails at 34 to 38 inches, continuous and graspable, sized 1¼ to 2 inches round.
• Posts and connections designed for the 200-pound concentrated load the code applies to guards and handrails.
• Welded panels and through-bolted post anchorage rather than glued or pinned joints, which matters in a valley bounded by the Calaveras Fault.
• Oven-cured powder coat over zinc primer or hot-dip galvanizing, in one color recorded on the spec sheet.

For most apartment balconies that means powder-coated aluminum railings where weight on older framing is a concern, or steel and ornamental iron where the look calls for it. Common stairs and accessible routes get ADA and commercial handrails. The spec sheet stays with you, so a future repair matches without anyone guessing.

Phased installation around tenants

Most multifamily jobs happen with every unit occupied. We plan the work as a sequence, not a single push, so no resident loses safe access to a balcony overnight.

Exterior stair towers and long walkways get their own sequence. We change handrails one flight at a time so there is always a code-compliant route down, and on walkways we stage panels so a run is never open for longer than the crew is standing next to it.

A balcony is never left open with its rail removed at the end of the day. If a section has to come off before the new panel goes on, a temporary guard or a locked door covers the gap.

Why owners hand us the railing scope

We are licensed and insured, fabricate in our own shop, and answer a local 925 number. Learn more about our shop.

Budgeting a building and next steps

Nobody can price a 40-balcony property honestly from a phone call. Cost tracks the number of elements, how each one is reached, the material and what the report actually flagged. As a starting point, installed railing in the Tri-Valley runs roughly $50–$200 per linear foot for powder-coated aluminum and $65–$135 per linear foot for ornamental iron. Corners and turns add about 20 to 30 percent, stairs cost more than flat runs, and permits typically run $50–$500. Upper-floor access that needs a lift pushes toward the high end.

The real figure comes from a free on-site estimate. We return a line-item proposal by building and by phase that you can take to ownership. Call (925) 438-6219 or send the inspection report through our contact page.

To make the site walk productive, have these ready: the inspector's report with photos, a unit and building count, any as-built drawings, notes on access limits such as carports or landscaping under balconies, and the color or style ownership prefers. With those in hand we can usually leave the walk with a clear list of what is in scope and what belongs to the framing contractor.
