Zoning answers how much. Design review answers how it looks. The two are separate processes with separate standards, and a project can satisfy every dimensional rule in the code and still be sent back for redesign.
Owners find this frustrating until they see the constraint on the other side: reviewers are not free to impose personal taste either. They apply ADOPTED CRITERIA, and criteria are public.
What design review covers
Scope varies by city and by project type, but the recurring subjects are massing and scale relative to neighbors, roof form, facade articulation, materials and finishes, window proportion and placement, entry treatment, landscaping, screening of mechanical equipment and trash areas, lighting, and signage where applicable.
Notice what is absent: floor plans, interior layout, and the owner's program. Review generally addresses what is visible and how it relates to its context, not how the household intends to live.
Who reviews, and at what level
Small projects are usually reviewed administratively by staff against a checklist. Larger or more visible ones go to an architectural or design body, sometimes to the planning commission. The threshold is set in the code, and it typically turns on size, visibility, or whether the project already requires another discretionary approval.
If a project also needs a variance or a conditional use permit, the applications commonly travel together and are heard at the same meeting. That is efficient and it means a design objection can surface in a hearing you thought was about setbacks. Our pieces on variances and on conditional use permits cover those companion tracks.
The criteria are the argument
Every well-run design process rests on written criteria: guidelines, standards, or a design chapter within a plan area. Whoever knows those criteria controls the conversation.
An applicant who says "we like it this way" is arguing preference. An applicant who says "the guideline calls for horizontal emphasis on street-facing elevations and this facade achieves it through the belt course and the window banding" is arguing the standard. Reviewers respond to the second.
The same is true for a neighbor. A comment that the design is ugly is not usable. A comment that a specific guideline about second-story mass adjacent to single-story neighbors is not met is directly usable, and it is the kind of comment that produces a condition.
The context question
Most criteria include some form of compatibility test with the surrounding built context. This is where the real judgment sits, and where applicants most often misjudge.
Compatible does not mean identical. Adopted standards in this field usually favor work that relates to context in scale, rhythm, and material while remaining legible as new. Copying a neighboring style badly is frequently criticized more sharply than a well-executed contemporary design that respects the massing pattern.
If a parcel carries a historic designation or sits in an overlay district, an additional and stricter standard set applies on top of the ordinary criteria. That layer is covered in our piece on historic overlays.
How to prepare a submittal that survives
Five habits that separate approvals from redesigns.
- Meet early. A pre-application conversation costs an hour and identifies the objections while the drawings are still cheap.
- Draw the context. Streetscape elevations showing the neighbors let a reviewer evaluate compatibility instead of imagining it.
- Specify materials honestly. Name the actual product and finish. Vague material notes get conditioned into a follow-up review.
- Address the criteria explicitly. A short narrative walking the guidelines in order, stating how each is met, does the reviewer's work for them.
- Show the mechanical and trash solution. These get flagged constantly and are easy to solve on paper.
The common failure points
Reviewers see the same three problems repeatedly, and all three are avoidable on paper.
Bulk at the boundary. A second story pushed to the side property line beside a single-story neighbor is the most frequently conditioned element anywhere. Stepping the upper floor back resolves most of the objection before it is raised.
Material substitution late in the process. A project approved with one finish and built with a cheaper lookalike creates an enforcement problem and a bad record for the next application. If cost forces a change, request the amendment rather than substituting quietly.
Landscaping treated as decoration. In most criteria sets, landscaping is doing work: screening, softening mass, defining the entry, managing runoff. A plan that treats it as an afterthought invites a condition that dictates it in detail.
Conditions instead of denial
Design bodies rarely deny outright. They approve with conditions: a material change, a setback of an upper floor, added landscaping, a revised fence detail, a lighting cutoff requirement. Those conditions become binding obligations, and they persist after a sale.
An owner should read them as construction instructions, because that is what they become. Our piece on conditions of approval explains how they are tracked and enforced.
If the decision goes badly
Design decisions are appealable like other planning decisions, on a short clock. An appeal that argues the criteria were misapplied has a chance. An appeal that argues the reviewers had bad taste does not.
The procedure and the deadline problem are covered in our piece on appealing a planning decision.
What buyers should notice
Two things. First, if a home you are buying was approved through design review, its approval carries conditions that may still govern exterior changes. Ask for them.
Second, if you plan visible exterior work after purchase, find out now whether it triggers review and at what level. A remodel budgeted for a permit timeline and delivered on a design review timeline is a budget problem that arrives late.
The underlying point
Design review is the part of the process people describe as subjective and that is largely written down. The criteria exist, they are public, and reading them before drawing is the whole trick.
Get the applicable guidelines from the city rather than from any summary, this article included, and check whether your parcel sits in a plan area or overlay with its own stricter set. Start at the City Development hub.

Frequently asked questions
Does design review cover interior layout?
Generally no. Review addresses what is visible and how it relates to context, including massing, materials, roof form, landscaping, screening, and lighting.
Is design review just personal taste?
It is supposed to apply adopted written criteria. Arguments that cite a specific guideline carry weight from applicants and neighbors alike; arguments about taste do not.
Does my project have to match the neighbors?
Usually not. Most criteria ask for compatibility in scale, rhythm, and material rather than imitation, and a well-executed contemporary design that respects the massing pattern often reviews better than a poor copy.
Can I appeal a design decision?
Yes, on the same short appeal clock as other planning decisions. The appeal must argue that the adopted criteria were misapplied, not that the reviewers had poor taste.
