Building Setbacks & Zoning in Lafayette, LA

Lafayette maintains 120 local ordinances across all categories, and 2 of those deal specifically with building setbacks & zoning. Here is a breakdown of what the city actually requires, what is prohibited, and where Lafayette falls on the strict-to-permissive spectrum compared to other cities.

Structure Height Limits

Lafayette's "RS-1" and "RS-2" single-family districts don't carry a flat maximum-story number the way denser districts do. Instead, Sec. 89-9(b)'s bulk plane caps a house at 3 stories for the first 50 feet from any lot line, adding one more story per additional 50 feet, and Sec. 89-27(a)(3) fixes each of those regulated stories at a maximum of 14 feet.

Key details: Bulk plane start: 3 stories within 50 ft of any lot line. Additional stories: +1 per extra 50 ft from setback. Restriction ends: Beyond 200 ft from any lot line. Regulated story height cap: 14 feet per story (§89-27(a)(3)). Attic exemption: Under 7.5 ft clear height, ≤50% of floor.

A house or accessory structure that exceeds the 3-story/50-foot bulk-plane progression relative to an RS district boundary, or that miscounts an enclosed attic as habitable space above the 7.5-foot attic threshold, fails the Article 10 permit-checklist review requiring disclosed "number of stories" and can be rejected at plan review before a building permit is ever issued.

Setback Rules

Lafayette ties yard setbacks to the zoning district under Code of Ordinances § 89-38(e)(3), but where parish land is unzoned, § 89-38(e)(7) sets a flat baseline: 20-foot front, 5-foot side, and 10-foot rear setbacks. A platted RS-1 corner lot gets its own worked example: 20 feet front, 10 feet on the side street, five feet on the interior side.

Key details: Unzoned parish setbacks: Front 20 ft, side 5 ft, rear 10 ft. RS-1 corner lot example: 20 ft front, 10 ft side street, 5 ft interior. Governing section: Code of Ordinances § 89-38(e). Small-lot reduction: 1% per foot under 100 ft deep. Appeal path: Planning & zoning commission or BOZA.

Building inside a required setback without qualifying for one of the encroachment-table exceptions in § 89-38(e)(4) is a zoning violation the administrator can act on; an owner facing practical difficulty can request an administrative modification under § 89-38(g), with any denial appealable to the planning and zoning commission or BOZA under §§ 89-68 and 89-69.

The Bottom Line

Lafayette's building setbacks & zoning rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Lafayette is broadly strict or permissive.

Keep in mind that Lafayette can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
