General Contracting — Tenant Improvements

Office, Medical & Retail Tenant Improvements

Turning a raw or dated commercial space into a working suite — on schedule and on budget. We manage the full buildout: permit coordination, MEP trades, finishes, and ADA compliance. We work in occupied buildings without shutting down the floor around you.

What We Do

From raw shell to move-in ready — without the scheduling drama.

A commercial tenant improvement sounds straightforward until you're three weeks in and the HVAC sub is waiting on a framing inspection that's waiting on the electrician. Coordination failures are the most common reason TI projects run late — and late means rent running while the space sits unoccupied.

YKCA operates as a licensed C-10 & General B contractor, which means we hold the general contract and manage the full trade lineup — mechanical, plumbing, sprinklers, finishes — under one schedule we actually control. The result is a buildout that moves predictably, with one point of contact when a decision needs to be made.

What's in Scope

Every phase of the buildout, managed under one contract.

From landlord shell prep through tenant fit-out and final inspection, we keep the schedule honest and the trade sequence tight.

Landlord vs Tenant Scope

We build both sides — warm-shell and spec buildouts for landlords before lease-up, and full fit-outs for tenants moving into raw or dated space. One contractor who understands both perspectives.

Occupied-Building Protocols

Off-hours and weekend scheduling for noisy work, dust containment barriers, coordinated utility outages with advance notice to property management — neighboring tenants stay operational.

MEP Coordination

HVAC, plumbing, and fire sprinkler trade partners managed under one schedule. Rough-in sequences are locked before walls close, so inspections don't stall waiting on one trade.

ADA & Title 24 Compliance

Path-of-travel upgrades, accessible restroom buildout, occupancy and daylight controls — scoped before permit submittal so plan check comes back clean.

Finishes & Flooring

LVP, carpet tile, polished concrete, paint, millwork, and storefront glass — installed after rough-in sign-off so finishes go in without rework.

Permits & Inspections

We pull the permit, manage the city relationship, and close out every inspection stage — framing, MEP rough, and final — delivering a complete permit file at close-out.

Working in Occupied Buildings

The hardest part of a TI isn't the construction — it's not disrupting everyone around it.

Multi-tenant buildings have no tolerance for surprise outages, uncontained dust, or noise at 10 AM on a Tuesday. Property managers need a contractor who communicates before anything happens — not after a complaint lands in their inbox.

We schedule demolition, core drilling, and any planned utility outages during off-hours or weekends. Dust barriers go up before demo starts. Every power or HVAC interruption is coordinated with property management days in advance, with a written window sent to affected tenants. The suite next door stays functional from day one to move-in.

We also handle the electrical and low-voltage scope in-house — panels, lighting controls, data, and security — so there's no gap between the GC rough-in and the electrical inspection. See our electrical-only scope

Off-hours scheduling

Noisy and disruptive work runs evenings and weekends — business hours stay clean for your neighbors.

ADA & Title 24 built in

Path-of-travel upgrades and energy compliance scoped before permit submittal — not discovered at plan check.

Trade sequence locked early

MEP rough-in is planned against the framing schedule — walls close on the right day, not after a callback.

FAQ

Tenant improvement questions, straight answers.

The schedule depends on the existing condition, design decisions, landlord approvals, permit review, equipment availability and inspection sequence. Develop a property-specific schedule with separate milestones for design, construction and opening readiness rather than relying on a generic number of weeks.

Occupied-building work needs a property-specific phasing plan. Review noise, dust, shared air systems, access and utility interruptions with building management before setting work hours. Some activities may require temporary relocation or planned shutdowns; uninterrupted operations cannot be assumed.

The lease and construction agreements determine the allocation. Review landlord-delivered work, allowance eligibility, excluded expenses and reimbursement timing together. The construction team can organize the scope and pricing; the lease team should confirm the commercial terms and legal interpretation.

Assign permit preparation, submission, correction responses and inspection coordination explicitly in the project agreement. The required design professionals, contractors and approval agencies depend on the scope. Confirm the closeout documents and final authorizations needed before scheduling occupancy.

Accessibility and energy requirements need separate review of the proposed alteration. Accessibility can involve altered features, connecting routes and shared facilities; lighting and mechanical changes can affect energy compliance. Have the design team identify the applicable requirements, code edition and responsibility boundaries before the scope and budget are fixed.

Five decisions worth resolving early.

Start with the short answer, then open the full guide for choices, examples and a practical checklist.

How should we budget around a landlord tenant improvement allowance?

Compare eligible scope, landlord-delivered work and payment timing. Reimbursement may arrive after construction invoices are due, so review the lease requirements alongside the project cash schedule.

What should we check before signing a lease for a build-out?

Review the proposed use, existing approvals, system capacity, accessibility and landlord delivery conditions. A coordinated walkthrough and records review help identify costs and dependencies before the lease commitment.

How should we plan the tenant improvement timeline?

Build the schedule from design decisions, landlord approvals, permit review, procurement, inspections and turnover. A property-specific sequence is more useful than a generic construction-duration estimate.

How can we reduce unexpected tenant improvement costs?

Define the scope and existing-condition assumptions before bidding, separate allowances from risk reserves, and document changes with their cost and schedule effects before authorization.

Control Tenant Improvement Costs Before Change Orders Start →

When should accessibility be reviewed for a tenant improvement?

Review it while the layout and lease scope are being developed. The assessment may involve the altered suite, connecting routes and shared facilities, with responsibilities coordinated among tenant, landlord and design professionals.
