Chapter 42 gives the Planning Commission two ways to let a plat depart from the rules, and the most useful thing to know before filing is how much of the code each one cannot touch.
A variance under Sec. 42-81 is the broader instrument: it reaches requirements of the chapter generally, and it rests on hardship or on strict application making the project infeasible because of unusual physical characteristics — or producing a development that is impractical or contrary to sound public policy. A special exception under Sec. 42-82 reaches only Article III, and rests on circumstances unique to the land, the proposed subdivision or the development — and not generally applicable to other land, subdivisions or developments in the city or its ETJ — rather than on hardship to the owner.
Both are barred from the chapter’s performance standards. Sec. 42-81(a) also bars a variance from the chapter’s definitions and from any provision of state law, and Sec. 42-81(g) puts Article IV outside the variance power altogether. So the honest summary is that relief exists, but the map of what it reaches is narrower than the existence of two named procedures suggests.
| Variance (Sec. 42-81) | Special exception (Sec. 42-82) | |
|---|---|---|
| Reaches | Requirements of Chapter 42 | Provisions of Article III only |
| Rests on | Hardship / infeasibility | Circumstances unique to the land, subdivision or development, and not generally applicable elsewhere |
| Ordinary vote | Majority of members present and voting | Majority of members present and voting |
| Vote on a protested replat | Three-fourths of members present, or such other number as state law sets | Three-fourths of members present, or such other number as state law sets |
| Cannot reach | Performance standards, definitions, state law, Article IV | Lot size, compensating open space, building lines, performance standards |
| Size limit on the relief | None stated | Not available at 33% or more |
From Sec. 42-81 and Sec. 42-82. Both sections also require that the intent and general purposes of the chapter be preserved and that the grant not be injurious to the public health, safety or welfare.
Sec. 42-81(a) and Sec. 42-82(a) both say the commission may grant relief when it finds that each of the listed conditions exists. These are not factors to be weighed against each other; a failure on any one is fatal, which is why Sec. 42-47(a)(4) and Sec. 42-48(a)(4) require the application itself to address every condition individually.
One category is expressly outside this. Sec. 42-81(a) grants the variance power "when the commission finds that each of the following conditions exist, except for variance requests submitted under subsection (e)." A vested-rights variance under Sec. 42-81(e) is therefore not judged against the five findings at all — it turns solely on whether the owner has established a vested right, and the commission shall grant it when they have. See below.
For a variance the five are: (1) either an undue hardship depriving the applicant of the reasonable use of the land, or strict application making the project infeasible because of unusual physical characteristics affecting the property, or producing a development that is impractical or otherwise contrary to sound public policy; (2) the circumstances supporting the variance are not the result of a hardship created or imposed by the applicant; (3) the intent and general purposes of the chapter are preserved; (4) the grant is not injurious to public health, safety or welfare; and (5) economic hardship is not the sole justification — cost alone will not carry a variance.
For a special exception the five are: circumstances unique to this land, subdivision or development and not generally applicable to other land, subdivisions or developments in the city or its extraterritorial jurisdiction; the result contemplated by the Article III standard is still achieved; the modification is not disproportionate; the intent of the chapter is preserved; and no injury to public health, safety or welfare. Where a provision of Article III sets out more specific findings of its own, Sec. 42-82(a) makes those control.
Whatever the commission finds becomes part of the record: both sections require the findings and the specific facts they rest on to be written into the official minutes of the meeting where relief was granted.
The commission shall not grant a special exception to any of the following: (1) Lot size requirements; (2) Compensating open space requirements; (3) Building line requirements; or (4) Performance standards of this chapter.
Sec. 42-82(a)(3) contains the only hard numeric limit on relief anywhere in these two sections, and its wording matters. It does not say the commission should be reluctant above some threshold — it says the commission shall not be authorized to grant a special exception if the modification of the standard is 33 percent or greater. That is a limit on the commission’s power, so no amount of merit in the application reaches it.
The same provision helps at the other end: a modification of a measurable standard by 10 percent or less is presumed not disproportionate. A small ask therefore starts with the presumption in its favour on that finding, though the other four findings still have to be made.
Every other provision here is permissive — the commission "is authorized to" grant relief. Sec. 42-81(e) is different. It says the commission shall grant a variance to an owner whose lot is subject to a special minimum building line or special minimum lot size requirement, on determining that the owner has established a vested right.
The test is reliance, and it has a date attached. The owner must show that, in good faith and material reliance on the rules that applied before, they either expended a substantial sum that cannot be recovered prior to the effective date of the special requirement, or irreversibly changed position before that date in a way that will require substantial future expenditure.
The section then puts the cheapest version of that argument on the back foot. It is a rebuttable presumption that holding a contract to purchase, or an option contract on, the affected property is not the expenditure of a substantial sum. Being under contract when the designation landed does not establish a vested right by itself — but the presumption is rebuttable, so it shifts what you have to show rather than closing the door.
Asking for relief can trigger notification under Sec. 42-83, and the cost of it falls on the applicant — Sec. 42-47(c) and Sec. 42-48(c) both say so expressly. Two limits before the mechanics: Sec. 42-81(f) and Sec. 42-82(f) impose it only where the property is all or partly within the city, and each then lists specific cases where no notice is required — those exemptions turn on Article III sections this page does not cover, so check them against your own application rather than assuming notice is owed.
The director has a choice under Sec. 42-83(a)(1). Either mail the owners of all lots or tracts within 300 feet of the plat boundary, at least 20 days before the hearing or first commission meeting — the 20 days attach to this option — or simply cause the information to be made readily available to the public in an electronic format, for which the subsection states no deadline at all. The director also notifies registered neighbourhood associations for the area, the district council member’s office, all at-large council offices, the Super-Neighborhood Alliance, the super-neighbourhood, and any management districts or tax increment reinvestment zones involved.
The applicant posts the signs. At least one, facing each public street or private roadway bordering the site, a minimum of four by eight feet, no more than 15 feet from the roadway, legible from it, up at least 20 days before the meeting. If more than four signs would be required you may ask the director to approve an alternative arrangement.
Two obligations run past the filing. If the plat is deferred or the hearing postponed, Sec. 42-83(c)(2) requires every sign to be updated to reflect any change in the date, time and place of the meeting — not the date alone — and proof of the change provided to staff. And Sec. 42-83(d) requires the signs to come down within 60 days after the commission acts, you withdraw, or the director deems the application inactive.
Relief does not set a precedent. Sec. 42-81(b) and Sec. 42-82(b) both provide that a grant applies only to the specific property it was approved for, and does not change the chapter or establish any policy, rule or regulation contrary to it. A variance your neighbour obtained is not authority for yours — though the facts that supported it are in the commission’s minutes, because both sections require the findings and their supporting facts to be recorded there.
Sec. 42-47(a) and Sec. 42-48(a) set out four requirements each, and they are close to identical: identify the specific requirement you want relief from, state the extent of the relief sought, give a detailed explanation of the hardship (variance) or of the circumstances and facts (special exception) that justify it, and provide a statement addressing each of the conditions the commission has to find.
You are not locked into your opening position. Sec. 42-47(b) and Sec. 42-48(b) both allow an application to be amended to request relief that was not sought initially — which is the same door Sec. 42-78(c) opens when the director refers an administratively reviewable plat up to the commission.
