Variance (land use)

Variance (land use) is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Variance (land use) rather than just read about it. In short: A variance is a deviation from the set of rules a municipality applies to land use and land development, typically a zoning ordinance, building code or municipal code. The manner in which variances are employed can differ greatly depending on the municipality.

Key takeaways

  • Variance (land use) belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Variance (land use) to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Variance (land use) from memory before moving on to harder problems.

Reference excerpt

A variance is a deviation from the set of rules a municipality applies to land use and land development, typically a zoning ordinance, building code or municipal code. The manner in which variances are employed can differ greatly depending on the municipality. A variance may also be known as a standards variance, referring to the development standards contained in code. A variance is often granted by a Board or Committee of adjustment.

Description A variance is an administrative exception to land use regulations. The use and application of variances can differ considerably throughout the great number of municipalities worldwide that regulate land use on this model. The issuance of variances may be very common, or nearly unheard-of in a given municipality. This can depend on a municipality's regulations, built environment and development pattern, and even political climate. One city may view variances as a routine matter, while another city may see variances as highly unusual exceptions to the norm. Community attitudes and political climates can change within a city as well, affecting the manner in which variances are granted even when no changes are made to the regulations governing variances. Typically, in the United States, the process for a variance must be made available to a landowner upon request, or the municipality may be in danger of committing a regulatory taking. The variance process has been described as "a constitutional safety valve" to protect the rights of landowners.

Types Two broad categories of variances generally are used in the practice of local land use planning: area (or bulk) variances and use variances. An area variance is the most common type. It can be requested by a builder or landowner when an odd configuration of the land, or sometimes the physical improvements (structures) on the land, requires a relaxation of the applicable regulations to avoid denying the landowner the same rights and use of the property enjoyed by owners of neighboring properties. A textbook example would be a house built on an oddly-shaped lot. If the odd shape of the lot makes it onerous for the landowner or builder to comply with the standard building setbacks specified in the code, a variance could be requested to allow a reduced setback. Another would be a house built on a sloping lot. If the slope of the lot makes it onerous to comply with the height limit—typically due to the way the municipality's code requires height to be measured—then a variance could be requested for a structure of increased height because of the special conditions on the lot. A use variance is a variance that authorizes a land use not normally permitted by the zoning ordinance. Such a variance has much in common with a special-use permit (sometimes known as a conditional use permit). Some municipalities do not offer this process, opting to handle such situations under special use permits instead. Grant of a use variance also can be similar, in effect, to a zone change. This may, in certain cases, be considered spot zoning, which is prohibited in many jurisdictions. In either case, the variance request is justified only if special conditions exist on the lot that create a hardship making it too difficult to comply with the code's normal requirements. Likewise, a request for a variance on a normal lot with no special conditions could judiciously be denied. The special conditions or hardship typically must arise from some physical configuration of the lot or its structures. The financial or personal situation of the applicant normally cannot be taken into consideration. Under most codes governing variances, approval of the variance must not result in a public health or safety hazard and must not grant special privilege to the property owner. In other words, when a variance is granted, any other property owner with similar site conditions should be able to obtain a similar variance; this criterion is often addressed by citing precedent.

Worked examples

Example 1 — a first encounter with Variance (land use)

Start with the simplest possible case. Write down what Variance (land use) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Variance (land use) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Variance (land use) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Variance (land use)

In research
Variance (land use) appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Variance (land use) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Variance (land use) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Local government in the United States, Zoning, so understanding it makes those chapters shorter.
In everyday life
Look for Variance (land use) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Variance (land use) in simple terms?

A variance is a deviation from the set of rules a municipality applies to land use and land development, typically a zoning ordinance, building code or municipal code. The manner in which variances are employed can differ greatly depending on the municipality.

Why does Variance (land use) matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Variance (land use)?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
