Impervious Cover

Austin, TX · City rule · Reviewed 2026-09-28

Austin limits impervious cover by property and zoning context, so roofs, driveways, patios, and other surfaces can constrain a project even when the use itself is allowed.

More about this rule

The rule in plain language

Land-use review considers impervious cover with zoning, setbacks, height, compatibility, landscaping, and other site rules. How a surface is counted depends on current code definitions and the site's approvals.

Common follow-up questions

What should I do first?

Start with a current survey and calculate all existing and proposed covered or paved areas using the City's current definitions.

What can change the answer?

Zoning, watershed, lot size, existing development, surface design, prior approvals, and redevelopment scope can change the limit and calculation.

What to keep in mind

Do not estimate only the new building footprint. Existing structures and paving count toward the property total, and gravel, decks, pools, or partially pervious systems need fact-specific classification.
