Austin demolition permits: the 50-year rule and what stops a teardown

What needs a permit

§25-11-37(A) is broad: a person may not demolish all or part of a structure without first obtaining a demolition permit. Partial demolition counts, which catches a lot of substantial remodels.

The exception in §25-11-37(B) is narrow and specific: no permit is required to demolish all or part of an interior wall, floor or ceiling. Strip the inside out and you are outside the requirement. Touch the envelope and you are inside it.

The 50-year rule, and why it is not just about age

This is the provision that decides whether a teardown is straightforward or a six-month conversation. §25-11-213 applies to buildings in a National Register Historic District, on an approved historic survey, individually listed, designated as a state or national landmark, in an H or HD combining district — or, catch-all, determined by the historic preservation officer to have potential for designation as a historic landmark.

You escape it only through §25-11-213(C), and read the conjunction carefully. The section does not apply if the historic preservation officer determines that the structure:

1. is less than 50 years old; and
2. does not meet at least two of the designation criteria in §25-2-352(A)(3)(b); and
3. is not a contributing structure in a historic area (HD) combining district.

All three must hold. Being under 50 years old is not on its own enough, and being over 50 does not on its own mean refusal — it means the section applies and the question gets asked properly.

It is 50 years, incidentally, not the 45 that circulates informally. A house built in 1976 crosses that line this year.

What the review does to your programme

Where §25-11-213 applies, the clock is set out in the section:

• the historic preservation officer completes review within five business days of a complete application and decides whether to place it on the Commission agenda;
• if agendaed, the Commission holds a public hearing within 60 days of a complete application;
• a sign goes up on the site and notice goes to property owners, residents and registered neighbourhood associations.

The building official then cannot issue the permit until the earliest of:

• the Commission deciding not to initiate a historic zoning designation case;
• the Commission approving a certificate of appropriateness, or making recommendations;
• 75 days after the first Commission meeting at which the application was posted; or
• 180 days after a complete application, for a contributing structure in a National Register Historic District or a pending HD combining district.

So the realistic worst case on an ordinary contributing structure is around six months from complete application — and that is the timeline running its course, not a dispute.

Notice to the neighbours

§25-11-37(D) requires the applicant — not the city — to notify adjacent one-family and two-family structures, and any multi-family component of other adjacent structures. The building official adopts the rules, but the minimum is set in the code:

• on a form approved by the director, specifying the date or range of dates on which demolition may occur, which must be between five and ten days after notice is given;
• mailed or placed on adjacent properties; and
• posted on the property, visible from the primary street frontage.

The five-to-ten day window is a constraint on scheduling, not just paperwork — the notice has to name when it will happen, and then it has to happen in that window.

Asbestos and materials diversion — where houses get off lightly

Asbestos survey. §25-11-38(B) bars the building official from issuing a demolition or renovation permit without a survey by a state-licensed inspector. But §25-11-38(C)(5) exempts a single family dwelling, or a residential use with four or fewer units. For most of what we build, this requirement does not apply.

Where it does apply, §25-11-38(D) is worth knowing: a survey of the building in its entirety means no further surveys for subsequent renovations or demolitions of that building. One thorough survey beats several partial ones.

Materials diversion. §25-11-39(C) requires it for construction projects exceeding 5,000 sq ft of new, added or remodelled floor area, and for commercial and multifamily projects requiring a demolition permit. A single-family demolition is not caught by the second limb — but a large single-family build can be caught by the first.

The permit expires, in two different ways

§25-11-95 sets two independent clocks:

• the permit expires if work does not begin within two years of issue; and
• it expires if the demolition is not complete within six months of the date work begins.

The building official may grant a single one-year extension, but only if the permittee asks before the permit expires. It must be in writing, though it does not require a formal application.

And a trap worth flagging: §25-11-95(D) states that an active demolition permit does not prevent expiration of a site plan under Chapter 25-5. Holding a live demolition permit does not keep your site plan alive alongside it.
