TI electricians: coordination skill matters as much as technical skill.
Commercial TI electrical contractor selection affects project timeline, cost, and quality. TI work differs from standard commercial — coordination with GCs and other trades matters more than for standalone scopes.

Choosing a TI electrician in Marin: look for documented commercial TI portfolio (30+ TI projects past 5 years), specific space-type experience for your project type (restaurant TI needs restaurant TI experience; medical TI needs medical TI experience), comfortable working with general contractors (most TI projects multi-trade), familiar with Marin AHJ TI processes, after-hours scheduling capability for some TI scopes. C-10 licensing is baseline; TI-specific experience differentiates qualified from less-qualified contractors.
01What makes TI electrical different from other commercial scopes.
TI electrical happens within a larger construction project managed by general contractor — different from standalone scopes (service upgrade, panel replacement) where electrical contractor manages everything. Coordination with other trades determines whether project completes on schedule. Schedule integration with GC's overall plan determines whether electrical work supports or delays project completion. Communication discipline matters as much as technical execution.
Multi-inspection coordination is more involved than standard commercial. Restaurant TI has 3 inspection regimes (building, fire, health); medical has additional health-facility considerations; office has standardized inspection sequence but with more frequent inspections (rough-in, trim, final). Inspection coordination requires preparation discipline, scheduling alignment, and quality work that passes inspections first time. Failed inspections delay overall project timeline disproportionately.
02Evaluation criteria.
TI-specific portfolio
30+ TI projects in past 5 years, with examples in your specific space type. Restaurant experience for restaurant TI; medical experience for medical TI; office experience can be more general but recent. References from GCs and prior tenants in similar space types.
GC working relationships
Active relationships with multiple Marin commercial GCs. Ask about communication patterns, project management capability, dispute resolution experience. Contractors who work well with GCs deliver smoother projects than those with adversarial trade relationships.
Inspection track record
Ask about first-pass inspection rate (good answer: 90%+ first-pass on TI projects). Multiple-inspection projects (restaurant) need especially strong inspection preparation. Contractors with high re-inspection rates indicate weaker quality or preparation discipline.

Common questions.
Do I need a specialty TI electrician or any commercial electrician works?
For straightforward TI scope (office TI, simple retail), any qualified commercial electrician works. For complex space types (restaurant, medical, larger retail), TI-specific experience meaningfully improves outcomes. The cost difference between average and best TI contractors is modest; the outcome difference can be significant. Match contractor capability to project complexity.
Should the GC select the electrical contractor?
GC may have preferred electrical contractors based on past working relationships — usually a quality signal. Tenant may also have preference or want to evaluate options. Both approaches work. For TI projects, tenant selection of electrical contractor is common in Marin; GC accommodates tenant choice within reasonable parameters. We work with both GC-selected and tenant-selected arrangements.
How do I get a TI electrical quote?
Provide architectural drawings, scope definition documents, equipment list (especially for medical/restaurant), space type and approximate square footage, target timeline. Site walk during quoting to verify existing conditions. Quote response typically 1-2 weeks for typical commercial TI; complex projects may take longer for accurate estimates.
What questions should I ask during the quote?
How many [your space type] TIs have you done in past 5 years? Can you provide references? What's your first-pass inspection rate? How do you coordinate with GCs? What's your schedule realism on your past projects (delivered on time)? Will the same crew that quotes execute the project? Good answers to these questions correlate with project success more than just lowest price.
How do you handle pricing — flat fee or hourly?
Both, depending on scope. Routine service calls and predictable scope (panel replacement, EV charger install, transfer switch install, fixture replacement) are flat-fee quoted up front. Diagnostic visits and emergency scope are hourly because we don't know what we'll find. Either way, you get a written quote before work starts on anything significant, and we don't proceed beyond the quote without your sign-off.
How quickly can you schedule?
Depends on scope and season. Emergency dispatch: same-day across Marin County (1-3 hours business hours, 1-4 hours after-hours). Same-day standard service: 3-6 hours from call when capacity allows; otherwise next business day. Scheduled service work: 1-3 weeks typical. Larger projects requiring permits and PG&E coordination: 4-12 weeks depending on scope. We're upfront about timeline at the quote stage.
What warranty do you offer on work?
Our standard residential warranty: 2 years on labor, manufacturer warranty on parts (varies by product — typically 1-10 years). Major installs (panels, generators, EV chargers) often have longer manufacturer warranties (5-10 years). If there's an issue with our work in the warranty period, we come back and fix it at no cost. We also stand behind work past warranty — repeat customers and referrals matter more than a transactional fix.
