Tenant Improvement Services for Custom, Code-Compliant Spaces

Tenant Improvement Services for Custom, Code-Compliant Spaces

When a new tenant moves in — or a business outgrows its current layout — a smart, efficient tenant improvement can make all the difference. At Alcala Architecture, we provide full-service design and construction for commercial tenant improvements across Southern California. From initial layout planning to final build-out, our team delivers customized, code-compliant spaces that meet your business needs and reflect your brand.

Whether you're a landlord preparing a space for a new occupant or a tenant upgrading your facility, we streamline the improvement process through our integrated architectural and construction services.

What Are Tenant Improvements?

Tenant improvements (TIs) are alterations made to commercial or industrial spaces to meet the specific needs of a tenant. This can range from small updates — like new finishes or lighting — to full interior reconfigurations.

  • Existing condition assessments
  • Space planning and layout optimization
  • Demolition and interior remodeling
  • Electrical, HVAC, and plumbing coordination
  • ADA accessibility compliance
  • Interior finishes and branding elements
  • Permit submittal and inspections
  • Final walkthroughs and occupancy support

Our team ensures the space not only looks right, but performs to current building codes and safety standards.

Commercial Tenant Improvement Services

Alcala Architecture serves a wide range of commercial clients throughout Southern California. We create flexible, efficient interiors designed to support productivity, flow, and customer experience.

  • Office reconfigurations and shared workspaces
  • Retail build-outs for storefronts or showrooms
  • Restaurants and hospitality upgrades
  • Medical and dental office renovations
  • Warehouse conversions and light industrial modifications
  • Multi-tenant commercial suite preparations

We balance aesthetics with function — delivering polished spaces that are ready for business.

Landlord and Property Manager Support

For landlords, maintaining flexible, leasable space is key to attracting and retaining tenants. We partner with property managers and building owners to prepare suites for occupancy, improve layout efficiency, or make necessary updates for compliance.

  • "White box" preparation and interior shell build-outs
  • Customizations based on lease agreements
  • Code upgrades for fire, egress, and ADA compliance
  • Energy and lighting improvements
  • Multi-tenant space coordination

Our team can work directly with tenants or manage improvements on behalf of ownership — providing documentation, scheduling, and construction oversight throughout the process.

Design-Build for Tenant Improvements

As both licensed architects and contractors, Alcala Architecture offers a streamlined design-build model for tenant improvements. This single-source delivery method reduces change orders, accelerates schedules, and improves budget control.

  • One point of contact from design through construction
  • Clear and consistent communication
  • Accurate as-builts and documentation
  • Rapid response to field adjustments
  • Coordination with building engineers, city agencies, and landlords

This approach is especially valuable for fast-track projects and complex occupancy requirements.

  • ADA and Code Compliance Upgrades

    Many tenant improvement projects involve bringing older spaces up to current accessibility and life safety standards. We identify gaps and implement solutions that meet California building code and ADA requirements.


    Services include:


    • Barrier removal and access route improvements
    • Restroom and entry modifications
    • Door hardware and signage updates
    • Emergency egress planning
    • Compliance documentation for final inspection

    We work closely with inspectors and plan checkers to keep your project moving and compliant.
