Bastrop P&Z narrows ADU rules: one ADU by right, second allowed administratively with infrastructure conditions

The Bastrop Planning & Zoning Commission on Dec. 19 approved an amendment to the development code adding accessory dwelling units (ADUs) to the lot‑occupation table and changing how many ADUs are allowed per property.

Why it matters: Staff explained the change adds ADUs to the table so regulations are clear and creates a two‑step approach: one ADU allowed by right; a second ADU may be allowed administratively by the Development Review Committee if the site meets parking, drainage and infrastructure requirements. Staff said parking guidance follows a bedroom‑based council decision (one parking space per bedroom) and emphasized appeal rights to the commission and council if staff denies an administrative ADU.

Public comment and rationale: Pablo Serna (1104 Hill Street) urged using net density per acre — including ADUs — instead of per‑lot allowances to protect neighborhood character and suggested parking requirements be expressed per dwelling unit. He told the commission a net density approach would avoid sudden intensification on small historic lots.

Commission response and decision: Commissioners and staff discussed alternatives (setbacks, impervious cover, administrative variances) and emphasized the need to protect neighborhood infrastructure and character. The commission voted unanimously to adopt the staff proposal: one ADU by right and administrative consideration for a second ADU when parking, drainage, water and sewer capacity and other infrastructure conditions are satisfied.

Next steps: The change is effective following the commission action and staff will return with related code clarifications (including further discussion of setbacks and density averages) in upcoming meetings.
