Tenant Improvement Architecture | Get Your Space Built Out Right
Commercial renovation and tenant improvement design that maximizes your buildout budget, accelerates permitting, and gets your business open on schedule.
The Challenge of Building Out a Commercial Space on Time and on Budget
Your lease is signed and rent is ticking — every month of delay costs real money
Understanding what your TI allowance actually covers versus what you'll pay out of pocket
Navigating ADA compliance, building codes, and permit requirements that vary by jurisdiction
Coordinating between landlord requirements, your business needs, and contractor capabilities without an experienced guide
We understand the pressure of a signed lease with a clock running. You need your space designed, permitted, and built as efficiently as possible — without cutting corners that create problems later. Whether you're a medical practice needing specialized rooms, a restaurant requiring health department approval, or a professional office wanting a space that reflects your brand, the buildout process has to be fast, budget-conscious, and done right the first time.
How Entero Architects Delivers Tenant Improvements That Work
We've designed tenant improvements for medical offices, restaurants, fitness studios, professional services firms, and retail businesses across Sonoma County and the Bay Area. Our approach is built around speed and budget efficiency — we know how to maximize your TI allowance, fast-track the permit process, and coordinate with contractors to get you open for business on schedule.
Speed to Occupancy
We front-load permit-critical items, maintain direct relationships with local building departments, and use overlapping design-permit-construction scheduling to compress your timeline. Typical TI projects go from kickoff to permit submission in 6–10 weeks.
Budget Optimization
We help you understand exactly what your TI allowance covers, identify what the landlord is responsible for versus your costs, and design to maximize value within your budget. No surprises, no scope creep.
Permit Expertise
We prepare complete, code-compliant permit packages that get approved the first time. Our familiarity with Sonoma County, Marin, and Bay Area jurisdictions means fewer plan check comments and faster approvals.
Our Tenant Improvement Design Process
From Vision to Reality: A Clear, Collaborative Journey
Initial Site Visit
Every project begins with an on-site visit where Entero Architects listens to your vision, gathers key information, and assesses your project's unique needs to set clear goals and expectations.
Fee Proposal
Once Entero Architects completes the initial site visit, we will send you a fee proposal of the cost to draw the plans for your project.
Programming and Pre-Design
Creating a clear vision is one of the most important steps in any building project, and it begins with programming and pre-design. During this phase, Entero works with you to develop a "basis of design" document that captures your goals and serves as a foundation for all future decisions.
Schematic Design & Design Development
Entero starts by documenting existing conditions—whether raw land or an industrial building slated for adaptive reuse—to establish a clear starting point. From there, we develop and refine conceptual designs, assess structural, mechanical, and electrical systems, and leverage our team of consultants to address any project challenges.
Construction Documents
This technical phase is where Entero Architects transforms the final design into detailed Construction Documents—technical drawings reviewed by local building officials for code compliance and used by your contractor to guide the building process.
Permit Submittal and Plan Check
This phase involves submitting the final construction documents to the local building department for plan check review. Your plans will go through a comprehensive review process by several departments, including Planning, Building, Fire Life Safety, Mechanical, Electrical, Plumbing, and Public Works. It's important to note that some back-and-forth communication is normal during this phase. Entero Architects will coordinate directly with building department officials to respond to any comments or required revisions, working diligently to keep the process on track.
Permit Issuance, Bidding and Construction
Once your permit review is complete, you'll receive your building permit and official job card—an exciting milestone! From here, most homeowners begin the search for a builder (unless you've chosen a design-build approach from the start). We will be right there with you, guiding you through the bidding process and helping you choose the contractor that's the best fit for your project. Once you've made your choice... it's time to kick things off—let the demolition begin!
Construction Administration & Inspections
As your project moves forward, the building department will conduct inspections at key stages to make sure everything is being built safely and up to code. These checkpoints include (but aren't limited to): trenching, rebar, foundation concrete, framing, mechanical, electrical, plumbing, exterior sheathing, stucco layers, insulation, drywall, and finishing work—just to name a few! Throughout construction, Entero will work closely with both you and your builder to help answer questions, solve problems, and keep things on track. We're with you every step of the way, providing construction administration services to support a smooth and successful build.
Final Inspection and Job Close Out
As your project nears completion and you're getting ready to move in, we'll work closely with you and your builder to wrap things up. This includes completing the final punch list inspections, collecting warranty information, issuing final certificates for payment, gathering release of liens, and helping to officially close out your project. Once the final walk-through is complete—congratulations, you're done! But our support doesn't stop there. Entero is still here for you with post-occupancy services, if you need them. Our relationship doesn't end when you move in—we're with you for the long haul, whenever you need us.
