Tomball council adopts Unified Development Code on first reading, clears path to codify zoning updates

Tomball’s City Council voted Nov. 17 to adopt the city’s new Unified Development Code (UDC) on first reading, consolidating separate zoning, subdivision, signs and manufactured‑home chapters into a single, updated code and setting the schedule for final adoption.

The UDC — presented by Erica Craycraft of consulting firm Friese & Nichols — combines four chapters and incorporates recent state law changes and recommendations from Tomball’s comprehensive plan. Craycraft said the update is intended to clarify rules, reduce duplicate definitions and make the code easier for staff and applicants to use. “The purpose of the update is to align with current state law…and to reflect our comprehensive plan,” Craycraft said during her presentation.

Why it matters: Council and staff said the UDC will simplify permitting, reduce internal conflicts in definitions and allow the city to more consistently handle development requests. The code also adds tools to encourage walkability and ‘‘missing‑middle’’ housing and sets clearer procedures for administrative approvals.

Key changes included in the draft

- Consolidation and definitions: Article 5 brings a single set of definitions into one place to eliminate conflicts between separate ordinances. Craycraft said this reduces ambiguity for applicants and staff.

- Zoning and housing tools: The draft creates an MF‑1 (multifamily 1) district to allow 3‑ and 4‑plex buildings in appropriate locations to expand ‘‘missing‑middle’’ housing options while noting the district is not mapped automatically.

- Rezoning protest threshold: The draft incorporates a state law change affecting rezoning protest thresholds. Craycraft explained the state updated how protests are counted and when a supermajority is triggered; in some circumstances the statutory trigger is now 60 percent of property owners in the relevant radius, which the city will apply consistent with state guidance. Councilmembers asked several clarifying questions about the geographic radius (state law uses 200 feet; Tomball’s notice radius is 300 feet) and how the supermajority requirement interacts with council quorum rules.

- Home occupations and short‑term rentals: The UDC aligns with the recent legislative rule that ‘‘no‑impact’’ home occupations must be permitted (no extra permit if the activity is not visible from the street, does not increase parking demand or cause noise). Craycraft said short‑term rentals remain treated as residential unless council opts to regulate them separately.

- Alternative compliance and parking: The code authorizes limited administrative deviations (for landscaping and parking) so staff can approve minor alternatives without a variance. Craycraft said the director may reduce off‑street parking by up to 15 percent under specified conditions, such as documented off‑site parking or an accepted parking study.

- Subdivision standards and connectivity: The draft adds maximum block lengths and requires street stub‑outs to adjoining undeveloped parcels except in clearly constrained situations (cemeteries, easements, etc.), to encourage future vehicular and pedestrian connectivity.

Adoption timeline and next steps

Council adopted the UDC on first reading at the Nov. 17 meeting; staff confirmed public hearings and the first reading have occurred and a second reading is scheduled for Dec. 1. Craycraft and city staff said the code is intended to be a living document and that council can revisit and tweak specific sections after the UDC is in place.

What council members said

Council members praised the effort to consolidate and simplify the code while raising routine questions about implementation and future tweaks. One councilmember noted the UDC can be amended over time and suggested staged workshops to review specific articles if needed; Craycraft agreed that periodic review workshops make sense.

Legal and procedural notes

The draft incorporates state law references discussed in the presentation, including the state provisions governing expiration of concept plans and the notice/threshold rules that affect rezoning protests as presented by staff. The city will continue following statutory posting and public‑hearing requirements as the ordinance proceeds to second reading.

Next step: The UDC will return for second reading and final action on Dec. 1; staff said administrative procedures and public guidance materials will follow adoption to help applicants and neighbors understand the changes.
