About the Review Disciplines
Technical Review
Any permit exhibits not sealed and signed by a Texas-registered architect or certified building designer will be subject to a limited
technical review. The technical review is not intended to be exhaustive of all possible building code requirements.
Erosion Hazard
There is a review of structural design if a property is located in the Erosion Hazard Zone, as defined by the boundaries located on the City
of Austin GIS map. These zones align with locations where water flow and watershed could lead to erosion damage of the surrounding
land features (e.g creeks, stream beds, etc).
Fire Review
There is additional review of a project if the square footage of a structure exceeds 3,600 square feet in area. The 3,600 sq. ft. includes the
total gross building area: all first, second, and additional floor areas; attached covered porches, patios, decks, and balconies; attached
garages; and any other attached roofed areas. The review ensures adequate proximity to fire hydrants and sufficient water supply to the
hydrants based on the total gross area of the structure. Properties within 200 feet of a hazardous pipeline may also require additional
review. Projects within the Wildland Urban Interface will require a fire review. Projects that will have NFPA 13D automatic sprinkler
system installed will require a fire review. All 3-unit projects will require a Fire review.
Floodplain Review
Any work requiring a permit on property located within 100 feet of the 100-Year floodplain will require additional review. If review is
anticipated, include supporting information such as FEMA elevation certificate form 086-0-033 and/or topographic surveys referencing
NAVD88. To check your property for proximity to a flood plain visit www.ATXFloodPro.com or the City’s
Floodplain Development
Information website.
Historic Review
There is additional review of exterior changes if property is a City Landmark or located in a Local Historic District, National Register
Historic District, H or HD zoned district, or partial demolition of exterior features on property over 45 years old
City of Austin | Residential New Construction and Addition Permit Application
8/12/2024| Page 6 of 9
Tree Review
All design proposals must abide by the Tree Preservation Criteria set forth in Section 3.5.2 of the City of Austin’s Environmental Criteria
Manual. Cut and fill is limited to 4” within ½ Critical Root Zones (foundations cannot adhere to this), canopy removal is limited to 25% or
less per tree, and 50% or more of the full Critical Root Zone must be kept at natural grade with natural ground cover. If proposing to
remove a tree that is dead, diseased or an imminent hazard, please provide a Tree Risk Assessment from a Certified Arborist and/ or
photographic evidence.
Austin Energy Review
All overhead and underground electrical facilities need to be clearly shown and labeled on the plot plan including: pad mount transformer
and pad, pull boxes, all underground electric wires on site including service wire, utility poles, all overhead wires on subject property and
adjacent properties including service wires, down guy wires, existing electric meter location. All electric easements and public utility
easements need to be shown and labeled on the plot plan. AE will review based on current Austin Energy Design Criteria
for required
safety clearance per section 1.10. Any construction not listed in this application will NOT be considered part of the review. Please note if
your project has existing transmission facilities and or transmission easements this BSPA and plot plan will be reviewed by our AE
Transmission group. The Transmission review is separate from the Distribution review. The Transmission review group may require
additional documentation than the Distribution review.
