Commercial Tenant Fit-Outs & Change of Use

A promising storefront, office or commercial suite still has to work for your business—and for the agencies reviewing it. Baca Williamson Architects, PLLC helps tenants, owners and landlords evaluate a space, plan the layout and prepare permit drawings for interior work, tenant changes and changes in use or occupancy.

Review the space before construction starts. A new tenant, different use or apparently simple renovation can affect occupancy, exits, accessibility, plumbing, mechanical systems, parking and agency approvals.

Projects we can help plan

  • Office and professional-service interiors
  • Retail stores and showrooms
  • Restaurants, cafés and food-service spaces
  • Medical or personal-service offices
  • Interior alterations in existing buildings
  • Tenant changes and changes in use or occupancy

Services may include

  • Existing-condition documentation
  • Zoning, use and occupancy review
  • Test fits and space planning
  • Permit and construction drawings
  • Accessibility and life-safety coordination
  • Structural and MEP consultant coordination

A clearer path from lease to permit

  1. Understand the business and the space. We discuss the proposed operation, staffing, customer areas, equipment and schedule.
  2. Review records and existing conditions. We compare the intended use with available certificates, plans, zoning information and the actual space.
  3. Prepare a test fit. We arrange the program while keeping exits, accessibility, utilities and likely approvals in view.
  4. Develop the permit set. We prepare architectural drawings and coordinate required engineering or specialty information.
  5. Support agency review. We respond to architectural comments and help the project team track outstanding approvals, construction and inspections.

What is a change of use?

It generally means the proposed activity or occupancy differs from the approved use of the space. The classification and filing requirements are determined by the applicable code and municipality.

Does a new tenant always need a permit?

Not everywhere and not in the same way. Some jurisdictions have a specific change-of-tenant process; alterations or a different use may require a broader filing.

Should an architect review a space before lease signing?

A feasibility review can help uncover zoning, occupancy or layout concerns before you commit, although it is not a guarantee of approval or construction cost.
