Turn an Austin Address Into a Feasibility Record

An online map or builder phone call can begin the process. Neither is a substitute for a coordinated property review. The deliverable should be useful even if the owner changes designer or contractor.

Confirm the reviewing authority

Map the parcel against Austin city limits and any relevant ETJ or neighboring municipality. Record the legal parcel, current zoning, subdivision, utility providers and appraisal information. Do not rely only on the postal city.

Inside Austin, the City’s Property Profile and Development Services resources are primary starting points. Outside it, use the matching jurisdiction guide. The difference can change the allowed use, application, inspections and fees.

Describe the proposed dwelling arrangement

Write the current and proposed number of dwellings. State whether the new home is detached, connected or internal and whether any building will be removed. Include the intended household use, bedrooms, accessibility goals, approximate size and privacy needs.

Then test whether the proposal belongs under standard ADU guidance, HOME Phase 1 two-unit or three-unit residential use, or another path. The HOME decision guide helps frame this discussion, but City review controls the property answer.

Build a source-labeled base plan

Gather the latest survey, recorded plat, easements, existing plans, title/deed information and available permit history. Draw the property at a useful scale and label where each dimension came from.

Show:

• boundaries and setbacks;
• existing roofs, porches and paving;
• easements and service corridors;
• tree trunks, canopies and likely protected root areas;
• grade, drainage paths and flood information;
• parking and vehicle access;
• potential dwelling footprints; and
• construction access and staging.

If the survey is old or does not show the information needed, define the update rather than stretching it beyond its evidence.

Separate regulatory fit from physical fit

A concept can appear allowed yet still be impractical. Score the leading placement on four independent tests:

1. Land-use fit: use, dwelling count, lot and development standards.
2. Building fit: separation, structure, energy and life-safety path.
3. Site fit: trees, grade, drainage, access and existing improvements.
4. Service fit: power, water, wastewater and equipment routes.

A “pass” in one column cannot cancel a major unknown in another.

Investigate trees and drainage early

Austin’s mature canopy and intense rain events can shape a backyard project. Plot significant trees and obtain professional input when the proposed building, foundation, trench or access route may affect them. Avoid assuming that moving the footprint a few feet solves root or canopy conflicts.

Document existing runoff and downstream conditions. New roof and hardscape alter impervious area and flow. The feasibility stage should identify whether civil, grading or drainage design is likely and which current City criteria apply.

Sketch all service routes

Identify the existing electrical service and panel, water meter/service, wastewater connection or septic system and likely HVAC locations. Draw at least one proposed route for each. Note elevation basis and access for installation.

Ask for a preliminary demand/capacity view where an upgrade could materially change cost. Austin Energy, Austin Water or another provider may need project-specific coordination. The site and utilities guide provides the detailed register.

Check addressing and access

Austin requires a unique address or building number for a new dwelling before the residential permit application. Confirm who requests it and when.

Also map ordinary resident access, emergency considerations and the contractor’s construction path. Narrow side yards, fences, overhead lines and protected landscape can change equipment, labor and restoration assumptions.

Test the budget against the actual concept

Prepare a high-level owner forecast using the likely size, design path, foundation, services and site work. Add professional fees, permits/provider charges, building work, restoration and reserve. Use current market figures only as reasonableness bands.

If the concept exceeds the owner’s limit, change scope during feasibility. Do not ask the estimator to hide known work inside a low allowance. See the complete cost guide.

Finish with a decision matrix

The report should conclude with one of four outcomes:

• Proceed: the principal path and next design stage are adequately supported.
• Proceed after investigation: named evidence must arrive first.
• Revise: another placement, size or dwelling arrangement is more credible.
• Stop: a controlling constraint or budget mismatch makes the current idea unsuitable.

For every open issue, record the responsible party, expected deliverable, target date and consequence if the result is unfavorable.

What a paid feasibility scope should identify

Ask the provider to state:

• records and official sources it will examine;
• whether a site visit and measurements are included;
• consultants included or excluded;
• number of placement or program options;
• level of utility and cost work;
• meetings and revision rounds;
• the final written/graphic deliverables; and
• whether the work can be used by another team.

Avoid a scope that promises only “research” or “a concept” without a decision file.
