Sec. 42-181(a)’s citywide minimums do not apply to a courtyard style development — its opening clause excludes lots in one that meets Sec. 42-194. What replaces them is not a lower minimum but an entirely different regime, and the headline number runs the other way: Sec. 42-194(e) sets a maximum lot size of 3,500 square feet, plus a cap of 1,800 square feet of floor area per unit.
Read the scope of that carve-out narrowly. The exception is written into Sec. 42-181(a) and reaches subsection (a)’s figures. Sec. 42-181(c) — which bars a subdivision plat from including any lot under 1,400 square feet unless the plat meets its own performance standards — is a separate subsection and contains no courtyard exception on its face. Nothing in the archived text resolves how the two interact, so this page does not tell you a courtyard lot may go below 1,400 square feet. Confirm that specific question with the Planning and Development Department before designing to it.
Sec. 42-194(a) is unusually explicit about why. The stated intent is to incentivise "a greater range of naturally occurring affordable housing options" and smaller homes with functioning open space in a compact pattern, closer to existing infrastructure and mobility options. The size caps are the mechanism: this is a tool for building small, and it will not accommodate a large house on a small lot.
Two gateway conditions in Sec. 42-194(b) come before any of the standards. The property must be submitted on a site plan showing compliance with the section, and it must be platted as a unified courtyard style development with single-family restricted lots, reserves and a courtyard access drive. A conventional plat that happens to include shared open space does not qualify.

The numeric standards of Sec. 42-194. Sec. 42-194(b) contains a summary chart of its own and states that where the chart, the drawings and the text conflict, the text controls — so the figures here are taken from the section text.
The minimum building line for a structure along a courtyard edge is 0 feet, provided there is at least 20 feet between opposing building facades across the courtyard, measured from edge to edge of the courtyard, including any pedestrian walkways.
Sec. 42-194(i) imposes a minimum on the main courtyard and a per-lot total, and both have to be satisfied. The main courtyard must be at least 480 square feet. Separately, at least 150 square feet of courtyard space per lot must exist within the plat boundaries.
From four lots up, the per-lot figure is the binding one — four lots already require 600 square feet against the 480 minimum, six require 900, and ten require 1,500. Additional courtyards may be used to reach that total and are not each required to meet the 480 square foot main-courtyard minimum, but every courtyard must be at least 12 feet by 12 feet to count toward it.
Sec. 42-194(j) then governs how lots relate to that space: at least half of all lots must front the main courtyard or a street, and "fronting" has a definition — at least 50 percent of the lot’s width or depth must face it. A lot clipping a corner of the courtyard does not count.
The open space is not an amenity that can be recovered later. Sec. 42-194(c) provides that common areas and courtyards cannot be replatted into any other use, and makes them subject to Sec. 42-193 — the partial replat rules, which independently restrict how a residential plat restriction may be amended. Every plat containing a courtyard style development must carry a notation to that effect on its face, so the restriction travels with the record.
Ownership and maintenance have to be arranged up front. Sec. 42-194(c)(1) and (2) require the common space to be restricted to the use and access of the subdivision’s owners and residents, and to be owned, managed and maintained under a binding agreement among the property owners. That agreement is a precondition of the development pattern, not an afterthought.
This is a recent provision. Sec. 42-194 carries a single enacting citation in the archived text — Ord. No. 2023-801, adopted 27 September 2023, effective 27 November 2023 — newer than most of Chapter 42, which carries enacting citations from 2013. The archived text establishes those dates and nothing more; how the department reads the section in practice is not something this page can tell you. Confirm a marginal reading with the Planning and Development Department.
This is how the code reads; confirm with the city — or ask a builder who's actually pulled this permit in Houston. The authoritative text is the Houston Code of Ordinances; permitting questions go to Houston Permitting Center.
