Deck Railing Height, Spacing & Structural Requirements
A guardrail is a critical life-safety barrier. We fabricate and install to your approved plans, specifications, and the governing California Building Code provisions. Requirements vary by jurisdiction, adopted code edition, and project, so confirm the specifics for your property with your building department or design professional.
Guard Height Guidance
In the City of San Diego, current guidance calls for 42-inch guards on elevated decks and balconies, including decks serving single-family homes and duplexes. See the City's deck information bulletin (IB 211). Guards are generally required where the walking surface is more than 30 inches above the floor or grade below. Any exceptions are determined by the governing code and your approved plans, and we build to the height those plans show.
Openings & 4-Inch Sphere
Pickets, bars, and infill are generally spaced so a 4-inch sphere cannot pass through, with specific provisions set by the governing code and your plans.
Structural Loads
Guards must meet the structural load requirements of the governing code. Required structural design and calculations are provided by the responsible design professional; we fabricate and install to those specifications.
Infill Style & Ladder Detailing
Vertical pickets, horizontal bars, or custom ornamental patterns, as specified. Where the governing code or plans limit climbable elements, we build to them.
Substrate & Attachment
Base plate and anchor details follow the approved plans and specifications. If we find field conditions that need attention from the owner, design team, or a framing contractor, we flag them before installation.
Custom-Fabricated Steel with Galvanizing and Powder Coating for Coastal Projects
We measure on site and custom-fabricate railings to your property's dimensions and applicable project requirements. Fabrication takes place at our El Cajon shop, which is equipped with metal benders, a hydraulic ironworker, and saws. Moisture is a common cause of corrosion on exterior steel, particularly near the coast, so finish and hardware selection matter. How long a finish lasts depends on exposure, the coating system, and maintenance.
- Hot-dip galvanizing (ASTM A123): For coastal projects, fabricated steel is sent out for hot-dip galvanizing, in which the steel is immersed in molten zinc to form a protective coating. We do this for coastal properties in areas such as Pacific Beach, La Jolla, Point Loma, Coronado, and Imperial Beach. See the American Galvanizers Association FAQ for general guidance.
- Powder coating: After galvanizing, the steel is powder coated for a durable, UV-stable finish, available in black, bronze, and custom colors.
- Compatible hardware: We select corrosion-resistant fasteners and anchors that suit each project's materials and exposure.
From Field Measurement to Finished Installation
Property managers, general contractors, and homeowners get a predictable workflow:
Scope & Photo Review
Send plans, sketches, or clear photos of your deck or balcony. Luis Sr. and Luis Jr. review the layout and can often provide a preliminary estimate.
On-Site Laser Walk
We visit to laser-measure spans, review grade transitions, note the mounting conditions, and take field templates for curved or irregular runs.
Itemized Written Proposal
You typically receive a comprehensive itemized proposal within 24–48 hours of the on-site visit, with materials, finish, and attachment details. Removal and haul-away of existing railings is itemized from the start.
Fabrication & Finishing
Luis Sr. and Luis Jr. oversee fabrication at our El Cajon shop. Finishing, including galvanizing and powder coating, is completed by our finishing partners.
Installation
Our crew sets posts, secures anchors per the plans and specifications, and cleans the work area.
Resident-Aware Job Sites
On occupied properties, we coordinate work with property management: advance notice (at least 24 hours), marked work zones, cord ramps across walkways, and a dedicated safety spotter on larger multi-family jobs. Luis calls with an end-of-day progress update, including when the crew will return. Before-and-after photographs document the project.

Frequently Asked Questions: Deck & Balcony Guardrails
Clear answers about guardrail requirements, materials, and our installation process.
What is the required height for balcony and deck guardrails in San Diego?
In the City of San Diego, current guidance calls for 42-inch guards on elevated decks and balconies, including decks serving single-family homes and duplexes. Guards are generally required where the walking surface is more than 30 inches above the floor or grade below. Requirements can vary by jurisdiction, adopted code edition, and project conditions, and any exceptions are determined by the governing building code and your approved plans. We fabricate and install to the height shown on your approved plans.
What is the 4-inch sphere rule for guardrails?
Building codes generally require that pickets, horizontal bars, or decorative infill be spaced so a 4-inch diameter sphere cannot pass through the guard's openings. The rule is meant to protect small children from falls and entrapment. Specific provisions and exceptions are set by the governing code and your approved plans.
Can you mount metal guardrails to existing wood deck framing?
Yes, where the framing is structurally sound and the attachment method is specified in the approved plans or by the responsible design professional. If the framing shows dry rot or structural damage, a framing contractor or carpenter must repair it before new metal guardrails can be secured.
Do you perform SB 721 or SB 326 balcony inspections?
No. San Diego Custom Iron Works is a licensed C-23 ornamental metal contractor, not an inspection agency or structural engineering firm. We do not perform state-mandated inspections, provide engineering calculations, or issue compliance certificates. We fabricate and install guardrails based on the plans, specifications, or findings provided by your licensed inspector, engineer, or architect.
How do you protect exterior balcony guardrails from salt air corrosion?
For coastal projects, we send fabricated steel for ASTM A123 hot-dip galvanizing followed by powder coating, and we select compatible, corrosion-resistant hardware for each project. How long a finish lasts depends on exposure, the coating system, and maintenance.
Do you remove and haul away old, damaged balcony railings?
Yes. Removal and off-site disposal of existing wood or metal railings is included in every itemized proposal.
Can you match existing balcony railings across our building?
Often, yes. Because we custom-fabricate to your property's dimensions, we can work to match existing tube profiles, picket spacing, cap rail styles, and powder coat colors where practical, so new guardrails fit with the rest of your property.
How do I get a quote for deck or balcony railing installation?
Send plans, sketches, or clear photos of your deck or balcony, and Luis can often provide a preliminary estimate. For a firm bid, Luis Sr. or Luis Jr. visits to take laser measurements, and you typically receive a comprehensive itemized written proposal within 24–48 hours of that visit.

Work Directly With the Fabricators on Your Guardrail Project
Luis Lazalde Sr. learned the trade in his father's shop at age 13, continuing five documented generations of Herrera metalworking. Today he works alongside his son, Luis Lazalde Jr. For property managers, general contractors, and homeowners, that means one accountable family team you can reach throughout the project.
