Why Orange County Custom Railing & Stairs Has the Best Straight-Run Stair Installation Service


Straight-run stairs remain the most practical choice for Orange County's diverse building stock, from multi-family developments in Santa Ana to single-family homes in Mission Viejo, and Orange County Custom Railing & Stairs has refined our installation approach over 20 years to address the region's specific demands. While less architecturally dramatic than curved or floating designs, straight-run configurations offer unmatched reliability for high-traffic commercial spaces and cost-effective solutions for residential projects. We've mastered material selection based on microclimate—coastal properties within five miles of the ocean receive pressure-treated lumber, galvanized fasteners, and marine-grade finishes that combat moisture, while inland installations in Placentia, Orange, and Anaheim utilize standard red oak, maple, or poplar with polyurethane sealants optimized for California's dry heat.


Our installation methodology emphasizes California Title 24 compliance, ensuring proper egress width, handrail extensions, and tread uniformity that satisfy both residential and commercial code requirements. We coordinate with Orange County building departments—each with distinct inspection protocols—to expedite permit approval and final sign-offs. Commercial projects benefit from our expertise in ADA-compliant nosing, slip-resistant tread treatments, and guardrail specifications necessary for office buildings and retail spaces throughout Irvine, Costa Mesa, and Brea.


Local material sourcing through Orange County lumber suppliers reduces lead times and supports regional businesses while ensuring consistent quality. Our closed stringer systems, box newel installations, and baluster spacing reflect the clean, functional aesthetic preferred in Orange County's residential market, delivering staircases that enhance property value through proven, time-tested construction methods rather than trendy design elements.

Straight-Run Stair Installation FAQs

  • How much does straight-run stair installation cost in Orange County?

    Straight-run stair installation in Orange County typically ranges from $8,000 to $45,000+ depending on materials, height, and application. Basic steel pan stairs with concrete fill for industrial use cost less, while commercial-grade designs with powder-coated steel stringers, hardwood treads, and aluminum or stainless steel railings increase pricing. Multi-story straight-run stairs for warehouses or office buildings requiring fire-rated construction and IBC-compliant egress widths fall on the higher end.

  • Who installs code-compliant straight-run stairs for commercial properties?

    Orange County Custom Railing & Stairs installs code-compliant straight-run stairs for warehouses, office buildings, retail centers, and industrial facilities throughout Orange County. Our installations meet CBC and IBC requirements for tread depth, riser height, handrail specifications, and egress width. We coordinate with building departments for permitting and work with structural engineers to ensure proper anchoring and load capacity for commercial applications.

  • What is the installation timeline for straight-run stairs?

    Straight-run stair installation takes 4 to 10 weeks: 1-2 weeks for engineering and design, 2-4 weeks for fabrication of stringers and treads, 1-3 weeks for permitting, and 2-5 days for on-site installation. Prefabricated steel stairs install faster, while custom-welded designs or multi-story installations require additional time.

  • Can you install straight-run stairs for warehouse mezzanines?

    Yes, Orange County Custom Railing & Stairs specializes in straight-run stair installation for warehouse mezzanines, storage platforms, and elevated work areas. We install industrial-grade steel stairs with open-grate treads, diamond plate surfaces, or solid pan treads meeting OSHA requirements for width, slope, and load capacity. Our mezzanine stairs integrate with pallet racking systems, conveyor platforms, and multi-level storage configurations.

  • What's the minimum space required for straight-run stair installation?

    The minimum space for straight-run stair installation depends on floor-to-floor height and code-compliant slope ratios. Residential applications typically require 9-12 feet of linear run, while commercial stairs need 10-15 feet to accommodate shallower rise-run ratios and wider egress requirements. For a standard 10-foot floor height, expect approximately 13-15 feet of horizontal run plus landing space. California Building Code mandates maximum riser heights of 7 inches and minimum tread depths of 11 inches for commercial applications, which determines total run length.
