Hardware specification for a single-family kitchen and hardware specification for a 40-unit apartment building share almost nothing in common. The criteria designers learn through residential work — finish quality, individual fit, sample matching — are necessary but not sufficient at scale. Multi-unit specification is its own discipline.
This guide covers what changes when you're specifying for ten units, fifty, or several hundred — written for the interior designers and architects we work with on apartment, condo, and mixed-use projects.
The first decision is finish standardization, not selection
On a single-family project, the question is which finish. On a multi-unit project, the question is how many finishes. Two? Five? One per floor plan?
The trade-off is straightforward. Fewer finishes mean simpler procurement, lower per-unit pricing, easier maintenance and replacement. More finishes mean more design differentiation between unit types and more flexibility in marketing.
The answer most projects converge on: one finish for everything, chosen for durability and broad appeal rather than for design distinction. The savings on procurement and the simplification of building maintenance almost always outweigh the design value of varying finishes between units.
Brushed Satin Nickel and Matte Black are the two finishes that account for ninety percent of the multi-unit work we ship. Both age well, neither dates quickly, both pair with a wide range of cabinet finishes.
Order tolerance and finish batching
Hardware is manufactured in finish batches. Within a single batch, finish is consistent within tight tolerances. Between batches, you can see subtle drift — particularly in finishes that involve hand-applied processes (oil-rubbed bronze, antique pewter, honey bronze).
For a multi-unit order, specify single-batch fulfillment in your purchase order. This means the manufacturer produces the entire order in one production run rather than pulling inventory from multiple existing batches. Single-batch orders can require longer lead times (six to twelve weeks) but eliminate the risk of finish drift between units.
Lead times for hand-finished hardware on multi-unit orders are typically:
- Standard machine finishes (polished chrome, brushed nickel, polished nickel): four to six weeks for orders up to 5,000 units.
- Hand-applied finishes (honey bronze, antique pewter, Tuscan bronze): eight to twelve weeks for orders up to 5,000 units.
- Custom finishes: twelve to sixteen weeks; minimum order quantities apply.
Spec for replacement, not just installation
Apartment and condo buildings live for fifty years. The hardware you specify will be replaced piecemeal as units turn over, finishes fail, and tenants damage cabinet fronts. Specify with replacement availability in mind:
- Choose hardware lines that have been in production for five-plus years and are unlikely to be discontinued.
- Prefer standard center-to-center distances (3", 3¾", 5", 6¼", 8") over custom sizes that limit future replacement options.
- Confirm the manufacturer's stated production commitment for the line — most established hardware brands provide a written commitment to maintain production for at least ten years.
Submittal documentation
Building owners and general contractors will require a hardware submittal package. The package should include, for every piece specified: full product specifications, finish samples (loose finish chips, not photos), MSDS or material safety documentation if requested, and a written warranty statement.
Top Knobs maintains submittal-ready documentation for every product in the line. Contact our trade desk for the documentation package and pricing for your project specifications.
Working with us
For multi-unit projects above 25 units, our trade desk handles a different workflow than our retail customer service. You'll get a single point of contact for the duration of the project, finish samples shipped to your office (not just to your client), single-batch order coordination, lead time and freight quotes priced specifically for the project, and submittal documentation prepared to your spec.
