What installation actually costs here
A cost page written for Riverside puts cabinet installation at $1,308 to $11,993 and gives a per foot figure of $150 to $380 for each linear foot of cabinets installed. That is a wide range because installation covers everything from fitting six boxes in a utility room to a full kitchen with a tall run and an island.
Nationally, installer labour on its own is published at $50 to $70 per linear foot, and the worked example alongside it is the most useful single figure in cabinet pricing: a professional charging $70 per linear foot to remove existing cabinets and assemble and fit new ones drops to $55 per linear foot when the old boxes are already out. That difference is the price of demolition, and it is the one line on a cabinet quote that a capable homeowner can take off the sheet without affecting the warranty on anything.
The published national average for a whole installation is $1,044, inside a typical range of $482 to $2,167 and an outer range of $164 to $6,187. A worked example totalling about $5,000 breaks down as about $900 for installation and about $4,000 for the cabinets, which is a reminder that in most kitchens the boxes are the big number.

Fitting cabinets you bought yourself
Supplying your own cabinets and paying for installation separately is a legitimate way to control a kitchen budget, and it works well when two things are true: what was ordered fits the room, and somebody checks that before the delivery arrives.
The single most useful thing you can do is send the order list to an installer before you place the order. An experienced fitter reading a cabinet schedule against a room measurement can usually spot the problems in ten minutes: a run that is an inch too long, a corner that has not been resolved, a sink base that is too narrow for the sink you have chosen, or an oven housing ordered for a different appliance.
The second thing to understand is the division of responsibility. An installer fitting supplied cabinets is responsible for the fitting, not for the design or the product. If the schedule is wrong, the fix is a new cabinet with a lead time, and the installation stops while that happens. That is not a fault in the fitting and it is not covered by the fitting quote, which is exactly why the pre order check is worth doing.
| Check | Why | When |
|---|---|---|
| Total run length against the measured wall | A run that is an inch over does not fit, and filler only absorbs so much | Before ordering |
| Corner resolution | Catalogue corner solutions assume a square corner | Before ordering |
| Sink base width against the chosen sink | A sink wider than its base is a common and expensive error | Before ordering |
| Oven and appliance housings against model numbers | Housings are appliance specific, including trim kits | Before ordering |
| Assembled or flat packed | Assembly is a significant part of the labour on a flat packed kitchen | Before quoting installation |
| Delivery condition and count | Transit damage and short shipments stall an installation | On delivery, before work starts |
Levelling, and why the floor is not the reference
Cabinets are levelled off the high point of the floor, not off the floor beneath each cabinet, and everything else is measured from a struck line around the room. That is the single technical decision that separates an installation that works from one that fights itself all week.
The reason is arithmetic. If each cabinet is set level on the floor beneath it, each one sits at a slightly different height, the run has a wave in it, and the countertop then has to bridge that wave. Levelling from the high point means every cabinet is shimmed down to a single plane, the run is flat, and the countertop template is straightforward.
In Riverside's housing that matters more than it does in newer stock. The median unit dates from 1976, 56.5 percent of the stock predates 1980, on American Community Survey 2024 five year estimates, covering 2020 to 2024, and slabs of that age have moved. A quarter of an inch of fall across a twelve foot run is ordinary. Shimming it out is routine; discovering it after the base run is fixed is not.
Scribing, which is most of the skilled time
Scribing is cutting a panel or a piece of trim to the exact shape of the wall it meets, so that the joint closes with no gap. It is the difference between a fitted kitchen and an installed one, and in an older house it is a large share of the hours on the job.
The alternative is caulk. A bead of caulk across a gap looks acceptable for a year or two, then cracks along its length as the house moves and the material shrinks, after which the gap is visible and the caulk line is visible as well. In a house with walls that bow half an inch across eight feet, that is not a small detail.
Scribe and filler allowances therefore belong on the quote explicitly. A quote for an older Riverside house that has no scribe allowance in it has either not looked at the walls or has priced a change order into the project without saying so.
Permits, licensing and the removal question
Installing cabinets is exempt finish work under the City of Riverside's own published list, which includes “Painting, papering, tiling, carpeting, cabinets, counter tops and similar finish work.” and appears on the Building and Safety permits page→. Permits attach to the services: plumbing for a moved sink, electrical for new circuits, mechanical or gas for a relocated range.
Where a permit is needed, two further City facts are worth knowing. Permits expire: a permit becomes invalid unless work commences within 180 days of issuance, or if work is suspended or abandoned for 180 days, with residential structures getting 12 months; the Building Official may grant written extensions of up to 180 days each. And a contractor pulling a permit in Riverside must hold a current City business licence alongside the state licence, and present a Workers' Compensation Insurance Certificate at issuance if they have employees.
On licensing, California requires a contractor licence for any work over $1,000 in labour and materials combined, and the classification covering this trade is C-6 Cabinet, Millwork and Finish Carpentry. Check a number at the CSLB licence lookup→.
One more requirement applies to the removal half of the job. Taking existing cabinets off a wall in a home built before 1978 disturbs painted surfaces, which is covered work under the federal lead rule, and the minor repair exemption of six square feet or less of paint per room inside is passed almost immediately. See the EPA renovation, repair and painting page→.
Sequence: where installation sits in a kitchen project
| Stage | Depends on | Blocks |
|---|---|---|
| Demolition and lead safe removal | Firm certification if the house predates 1978 | Everything |
| Plumbing, electrical and gas rough in | Permits and inspections | Closing up walls |
| Flooring, if it is going in first | The decision about cabinets before or after | Cabinet installation if chosen first |
| Cabinet installation | A complete and correct delivery | Countertop templating |
| Countertop template and fabrication | Installed cabinets, and a final sink selection | Splashback and final plumbing |
| Splashback, hardware and punch list | The countertop being in | Handover |
The fixed constraint is that countertops are templated off installed cabinets, never off a drawing, which is why cabinet installation sits in the middle of the sequence rather than near the end.
How the project runs
- 1Check the delivery before anything is opened
Count the boxes against the schedule, check for transit damage, and confirm that what arrived is what was ordered. Discovering a wrong cabinet on day three of a four day fit is the single most common cause of a stalled installation.
- 2Find level, plumb and the high point
A laser line around the room, the high point of the floor identified, and the walls checked for bow and for plumb. Everything else in the installation is measured from that line rather than from the floor, because the floor is not flat.
- 3Set the base run first
Base cabinets are levelled off the high point of the floor and shimmed down from there, joined to each other and fixed into framing. Getting the base run dead level is what makes the countertop template straightforward and the uppers easy.
- 4Hang the wall cabinets
Off a fixed rail or a struck line rather than off the base cabinets, so the gap between base and wall is consistent even where the floor and ceiling disagree. Fixed into framing, with blocking added where the studs are not where the drawing wanted them.
- 5Scribe, fill and trim
Every point where cabinetry meets a wall or ceiling is scribed to the surface rather than caulked across a gap. This is the step that separates a fitted kitchen from an installed one, and it is almost all of the skilled time on an installation.
- 6Hang doors, adjust and hand over
Doors and drawer fronts on, hardware fitted, every reveal adjusted, drawers run under load, and the job closed against a written punch list rather than a verbal confirmation.
What to check before you sign
- A demolition line priced separately so you can choose to do it yourself
- A scribe and filler allowance stated, not assumed
- An adjustment pass included in the scope
- For supplied cabinets, a pre order check of the schedule against the measured room
- Whether flooring is going in before or after, decided before either trade starts
- Firm lead certification if the house predates 1978, which covers most of Riverside
- The CSLB licence number, checkable in ninety seconds
The three checks that happen at install, not on the drawing
Installation is where a drawing meets a house, and three requirements are checked at that point regardless of whether the job needed a permit. They come from the electrical, mechanical and energy codes rather than from cabinet practice, and the clearest published list of them in this service area is the City of Redlands residential kitchen renovations handout→, which cites the clause numbers directly. The handout also explains why a modest looking installation can pull work with it: “Removal and replacement of the base cabinets and counter top will require compliance with the electrical outlet location requirements of the code.”
| Requirement | Clause cited | What it means during installation |
|---|---|---|
| A countertop 12 inches or wider requires a receptacle outlet | CEC 210.52(C)(1) | Any base run wider than a foot pulls a receptacle into the backsplash above it, so a continuous unbroken splash is only possible where the cabinet below is narrower than that. |
| A receptacle is required within 24 inches of any point along the countertop | CEC 210.52(C)(1) | This is the rule that sets how many outlets land in a long run, and it is measured along the counter rather than per cabinet, so a four foot and a six foot cabinet can need the same number. |
| Kitchen outlets sit on or above the countertop, and not more than 20 inches above it | CEC 210.52(C)(5) | The 20 inch ceiling is why a 15 inch splash gap with a tall upper above it still works, and why raising the uppers to gain storage can strand an outlet outside the allowed band. |
| A ducted metal exhaust hood with a smooth interior surface and back draft protection | CMC 504.1.1 and 504.3 | A recirculating hood hidden in a cabinet is not the same thing as a ducted one, and the duct route decides whether the cabinet above the hob can hold anything at all. |
| Minimum 30 inch vertical clearance above the cooktop surface to combustibles or metal cabinets | CMC 922.3 | This is the single most common reason a drawn elevation has to change. The cabinet or hood above a hob cannot simply be set at the same height as the rest of the run. |
| Undercabinet lighting switched separately from other lighting systems | California Energy Code 150.0(k)2.K | A second switch leg has to reach the run. It is a trivial cost during a cabinet job and an expensive one afterwards. |
| An approved air gap fitting on the discharge side of the dishwasher | CPC 807.3 | The air gap has to surface above the flood rim, which usually means it comes up through the countertop beside the tap rather than hiding inside the cabinet. |
| Disposal cord 18 to 36 inches, dishwasher cord 36 to 78 inches, both with a grounding type attachment plug | CEC 422.16(B)(1) and (B)(2) | Cord length decides where the receptacle inside the sink base has to sit, which decides which side of the cabinet the pull out waste bin can use. |
Clause numbers as cited in the City of Redlands residential kitchen renovations handout, which cites the 2019 code editions. These are state code clauses rather than Redlands ordinances. Confirm the current cycle with your own city's building department.
Of those, the thirty inch minimum vertical clearance above a cooktop to combustibles or metal cabinets is the one that most often forces a change on the day. An elevation drawn to keep the upper run at a single consistent height is attractive on paper and sometimes cannot be built, because the cabinet or hood above the hob has to respect that dimension. Catching it at the drawing stage costs nothing. Catching it with the run already hung costs a cabinet.
The second is outlet position, and it is the reason an installer should see the electrical layout before the uppers go on. A receptacle is required within twenty four inches of any point along the countertop, and kitchen outlets sit on or above the counter and not more than twenty inches above it. Hang a tall upper run that closes the splash gap down to twelve inches and an outlet can end up outside the allowed band, which is an electrical correction rather than a joinery one.
The third is the hood duct. A ducted metal hood with a smooth interior surface and back draft protection has a physical route, and that route decides whether the cabinet above the hob is a storage cabinet, a decorative panel or a chase. It is the single item most worth confirming before a cabinet schedule is signed.
Installation in a garage, where a different rule applies
A meaningful share of installation work in this market is in a garage or a laundry off one, and the wall there is not an ordinary wall. The California Residential Code requires the separation between a garage and the residence to be not less than 1/2 inch gypsum board or equivalent applied to the garage side, and not less than 5/8 inch Type X gypsum board or equivalent where a habitable room sits above the garage. The code section is published here→.
For an installer that means fixing to the face of the membrane and never recessing into it. It also means two door rules worth knowing before a layout is set out: Openings from a private garage directly into a room used for sleeping purposes shall not be permitted. Other doors between garage and residence have to be solid wood doors not less than 13/8 inches in thickness, solid or honeycomb-core steel doors not less than 13/8 inches thick, or 20-minute fire-rated doors and must be self-latching and equipped with a self-closing or automatic-closing device, so a run that blocks that door’s swing or defeats its self closer is a run to redraw. And ducts in the garage or passing through the separation have to be at least No. 26 gage sheet steel with no openings into the garage.
Why countertops get templated after installation
Countertops are templated off installed cabinets rather than off the drawing, and in a city whose median house dates from 1976 that sequence is not a preference, it is the difference between a scribed back edge and a caulked one.
The reason is arithmetic. A template taken from a drawing describes where the cabinets were supposed to be. A template taken from installed and levelled carcasses describes where they are. In a house whose walls bow and whose ceilings fall over a run, those two differ by enough to show, and the difference lands at the one joint a homeowner looks at daily. Templating late costs a few days in the programme and removes the single most common visible defect in a kitchen installation.
The same logic governs the order of everything else at this stage. Cabinets are set level and plumb to themselves rather than to the wall, then scribed to the wall. Hardware is adjusted after the run is fixed rather than in the shop, because the reveals follow the installed carcass. Appliances are fitted after the tops so their openings can be verified against the real aperture. And the job closes on a written punch list, because a verbal one is an argument waiting to happen.
