Investment and duration figures are estimates. Your written quote sets the final price and schedule.

Kevin's company was finishing an office tenant improvement in the Corona business park, with 3 break room counters on two floors and a move-in date that could not slip. We installed white quartz after hours so the floors already occupied stayed open, one floor per evening, an estimated $3,400 to $5,600 job spread over an estimated 1 to 2 days of night work. All three break rooms were finished before the tenant's move-in date, and the general contractor closed the suite on schedule.

Scope and Project Size for Tenant Improvements

Our tenant improvement work in Riverside County ranges from a single break room counter to every stone surface in a multi-suite buildout, and these are the scopes we bid most often:

  • Office break rooms and coffee stations, each scoped like a wet bar or home bar top with a sink cutout.
  • Reception and transaction counters, built to the counter height shown on your accessibility sheets.
  • Medical and dental suite tops for nurse stations and lab counters, often solid surface with an integrated sink.
  • Full staff kitchens on a corporate floor, scoped like a kitchen countertop replacement (30 to 45 sq ft) per kitchen.
  • Restroom vanity runs on every floor of an office building, priced per top.

Offices, Medical Suites and Retail Spaces We Build For

Tenant improvement demand in our area comes from real building stock: office suites downtown near the county buildings, the Hunter Industrial Park and Sycamore Canyon Industrial Park, and medical offices around Riverside Community Hospital and the Kaiser campus. In Corona we work the office and biotech suites of the business park corridor, in Eastvale the distribution offices of the Goodman Commerce Center, and in Temescal Valley the small professional suites along Interstate 15. Retail TIs at centers like the Galleria at Tyler and Riverside Plaza add cash wraps and display tops to the list.

How a Tenant Improvement Countertop Job Runs

A tenant improvement countertop job runs on the general contractor's schedule, and our part of it follows seven fixed steps.

  1. Plan review and takeoff: we count every top, cutout and edge from the casework sheets.
  2. Bid: a written proposal with the material, finish and per-top pricing broken out.
  3. Submittals: slab photos, color samples and shop drawings for the architect to approve.
  4. Field template: a laser template after the casework is set, so the stone fits the cabinets actually installed.
  5. Fabrication: wet-cut and polished in our Riverside shop, typically 1 to 3 weeks after the field template.
  6. Install: at night or on a weekend when the building is occupied, coordinated with the plumber for sink and faucet hookups.
  7. Closeout: punch walk, care sheets and the warranty letter for the owner's file.

Working in Occupied Office and Medical Buildings

Most tenant improvements happen in buildings where the neighboring suites stay open, so we treat quiet and clean as part of the scope. Stone arrives finished from the shop, field cuts are kept to small trims under dust extraction, and slabs ride the freight elevator on protected carts at the times building management sets. Medical buildings get an install window outside patient hours, and the work area is sealed off from occupied corridors.

Tenant Improvement Countertop Pricing in Riverside

Tenant improvement countertops in Riverside are priced per top or per square foot from the plans, and installed surfaces are estimated at roughly $65 to $145 per sq ft for quartz, $70 to $130 per sq ft for solid surface and $55 to $120 per sq ft for porcelain.

SurfaceEst. installed priceWhere it fits in a TI
Engineered quartzEst. $65 to $145 per sq ftBreak rooms and reception, never needs sealing
Solid surfaceEst. $70 to $130 per sq ftMedical and lab tops, integrated sinks
Porcelain and sintered stoneEst. $55 to $120 per sq ftHot coffee stations, stain resistant
GraniteEst. $55 to $135 per sq ftLobby and executive suites, sealed at install

The count of tops, sink and grommet cutouts, edge upgrades and after-hours labor move a TI price the most, and repeated tops on several floors typically come in toward the low end of each range.

These numbers are budgetary estimates for Riverside and are subject to change; the written quote, confirmed on bid from your drawings and the field template, sets the final price and the install schedule.

Why General Contractors Choose Riverside Custom Countertops

General contractors choose us because one company handles takeoff, fabrication and install, so the stone schedule never depends on a broker.

After 12 years of Inland Empire work, we can send references from builders and property managers with the bid.

Tenant Improvement Countertop Questions

What is the smallest TI job you bid?

A single break room counter of roughly 12 to 20 sq ft is the smallest tenant improvement we bid, typically estimated at $750 to $2,400 installed.

Do you bid from TI drawings?

Yes, we bid from the architect's drawings and the finish schedule, then confirm every dimension with a laser template once the casework is in place.

How soon after award can you install?

Most TI tops install an estimated 1 to 3 weeks after the field template, so we schedule the template the day the casework installer finishes.

Can you work after hours in an occupied building?

Yes, night and weekend installs are standard on occupied floors, which is how the Corona office got one floor per evening.

Do you price repeated tops per unit?

Yes, repeated break rooms and vanities are priced per top, the same way our builder white quartz unit turnovers are priced, and volume typically lowers the per-top estimate.

Who supervises on site?

Our lead installer runs every install, and our estimator remains the general contractor's single point of contact.

Do you use in-house crews or subcontractors?

Our own crews template, fabricate and install every top, with only the plumbing hookup handled by the project plumber.

What closeout documents do you provide?

You get finish care sheets, the warranty letter and the quartz maker's warranty details for the building owner's file.
