Where we build in Danville, and what each area needs
Custom railing in Danville is mostly a replacement trade, because the town filled in early. Danville started turning suburban in 1947 with tracts like Montair and Cameo Acres, and I-680 arrived in the mid-1960s. Census figures put 30% of today's homes in the 1970s and 27% in the 1990s, with only about 6% built since 2000.
Montair and Cameo Acres bring us porch, step and deck rails that are original or patched many times over. Sycamore Valley, Greenbrook and Diablo Vista mean second-story deck guards, two-story stair upgrades and pool gates. Magee Ranch and the Green Valley Rd hills are steep lots where the deck rail frames a view of Mt. Diablo. Old Town, along Hartz Ave and Railroad Ave, calls for iron that respects the town's heritage.
Permits: Town of Danville Building Division / Permit Center
Danville became a Town on July 1, 1982, and it runs its own counter. The Building Division / Permit Center is at 500 La Gonda Way (925-314-3330), open Monday through Thursday 7:30 to 4 and Friday 7:30 to 1, so plan Friday visits for the morning. Applications move through the Town's online Permit Portal (CSS).
Railing jobs often grow into deck jobs, and Planning's Accessory Structures handout (revised 11/5/25) draws a line worth knowing: a ground-level deck keeps 5-foot side and rear setbacks, but an elevated deck must meet the same setbacks as the house. That rule can decide whether a deck extension is buildable at all.
For small decks, ask the Town. Most Tri-Valley departments, including Dublin, Pleasanton, Walnut Creek and the County, exempt only small, low, detached decks, and we confirm Danville's answer before fabrication begins.
Heritage review, aging decks and Danville's Very High fire areas
Old Town and the Heritage Resources list
Danville has 21 designated Heritage Resources, 20 structures and one tree, each marked with a brass plaque and overseen by a Historic Design Review Committee. Other exterior projects may go to the Design Review Board, which meets on Thursdays. Near those properties we lean toward period-appropriate iron: square or round pickets, simple collars and cast accents instead of modern cable.
Decks that have outlived their rails
Five decades of mid-80s July heat leave 1970s wood rails checked, split and loose at the posts. Replacing more than about half of a guard is commonly treated as new work that must meet today's 42-inch height, even when the old rail stood at 36 inches; we verify that with the Town. The USGS describes the northern Calaveras Fault running from Danville to Calaveras Reservoir, so new posts are through-bolted to framing.
Very High fire areas on the 2025 maps
Among the cities we serve, Danville is the only one with Very High areas on the State Fire Marshal's 2025 local maps. Areas historically mapped that way include Magee Ranch, Cameo Acres along Green Valley Rd, and the Las Trampas Ridge edge. Chapter 7A, now in the California Wildland-Urban Interface Code (Title 24, Part 7), governs new buildings in Very High zones; remodels of existing homes are generally exempt. A deck rail still sits right where embers collect, and metal or tempered glass will not feed a fire. Check your parcel at osfm.fire.ca.gov/fhsz.
What custom railing costs in Danville
Three local factors push Danville quotes up: tearing out old wood rails and repairing the rim joist beneath them, hauling material up hillside lots, and the finer detailing heritage-minded owners ask for.
| Railing | Per linear foot, installed | Usual project range |
|---|---|---|
| Exterior deck railing (all materials) | $20–$600 | ~$400–$4,800 |
| Ornamental iron | $65–$135; hand-forged $300–$900 | ~$700–$6,000 |
| Cable | $75–$260 | ~$3,750–$13,000; about $9,000 for 50 ft |
| Glass | $150–$600 | Premium tier |
Expect permits around $50–$500 and 20–30% more for each corner or turn. We publish ranges so you can budget, then price your Danville job at a free on-site estimate. Call (925) 438-6219.

FAQ

Who handles railing permits in Danville?
The Town of Danville Building Division / Permit Center at 500 La Gonda Way, phone 925-314-3330. It is open Monday through Thursday 7:30 to 4 and closes at 1 on Fridays, and applications go through the Town's online Permit Portal (CSS). If your railing is part of a deck change, the Planning Division's setback rules may also apply. We prepare the railing drawings and can submit them for you.
My home is near a Danville Heritage Resource. Can I still choose a modern railing?
Possibly, but expect more review. Danville's 21 Heritage Resources are overseen by a Historic Design Review Committee, and other exterior changes may go to the Design Review Board. Period-appropriate iron with simple pickets tends to suit Old Town better than cable or frameless glass. We can sketch both options so you can talk with Town planners before committing to fabrication.
Do I have to use noncombustible railing on a Very High fire area lot?
Chapter 7A wildland rules apply to new buildings in Very High zones, while remodels of existing homes are generally exempt. That means a rail replacement on an existing Danville home is usually not forced into specific materials. We still recommend steel, aluminum or tempered glass on these lots, because wood rails at a deck's edge catch embers. Confirm your zone at osfm.fire.ca.gov/fhsz and any rules with the Town.
My 1970s deck railing is only 36 inches tall. Does it need to be 42?
An existing rail that met the code of its day is not automatically illegal, but once you replace it, or more than about half of it, departments commonly require today's 42-inch guard with 4-inch sphere spacing. We confirm that with the Town for your project. Raising a rail on an old deck often means new posts as well, which we include in the free estimate.
