Testing a $171,400 renovation budget for a 1,290 sq ft Austin country home

If this estimate is wrong, I could commit most of the money before discovering that essential work has been left out. The working budget is $171,400 for renovating a 1,290 sq ft, five-bedroom country home in Austin, without adding any floor area.

I have allowed for new kitchen and bathroom work, floors, decorating, an electrical review and some energy-efficiency improvements. Before deciding how much contingency to hold, I want to understand what is behind the walls and what each contractor has omitted. Which inspections would you commission first, and how detailed should the electrical scope be? I would also ask bidders to identify long-lead materials and explain how those delivery dates affect the order of work.
 
With several rooms and systems involved, I would keep contingency separate from the quoted work rather than letting it disappear into allowances. Something in the 15–20% range would be my starting point until access and existing conditions are clearer. Ask each contractor to list exclusions for demolition, electrical corrections, plumbing behind walls, moisture damage, permits and making good after investigative work.
 
A few missing facts could change that answer: approximate age, foundation type, number of bathrooms, whether it is occupied during construction, and whether water and drainage are municipal or private. Also, can the plumbing be reached from below, and has anyone opened the electrical panel? Five bedrooms in 1,290 sq ft suggests sequencing and storage will be tight even without an extension.
 
I’m less convinced that choosing a contingency percentage first solves the problem. Spend some effort reducing uncertainty before fixing the number: selective openings in the wet areas, a clearly defined electrical inspection, and a plumbing assessment focused on access and condition. A smaller budget for investigation can be more useful than adding a large reserve while leaving every contractor to assume something different.
 
Daniel’s point is important, but some reserve still needs to survive the investigation because not everything will be visible. I’d ask bidders for a room-by-room sequence showing when services are isolated, inspections occur, walls are closed and finishes begin. Also identify every owner-supplied item and its required delivery date. A cheap cabinet or fixture that arrives late can hold up several trades.
 
How are the “moderate energy upgrades” defined? That phrase can hide a lot of scope. I would separate insulation or air-sealing work from equipment and electrical work, then decide it only after moisture paths are understood. Otherwise you risk improving one part of the envelope and discovering that an existing leak or ventilation issue needed attention first.
 
One terminology point for the opening poster: by “survey,” do you mean a property survey, a building-condition inspection, or specialist visits? A boundary-style survey will not answer the hidden-condition questions being discussed. And no extension does not automatically mean no structural work—demolition may expose framing that needs repair. Ask who decides when that becomes an engineer question and how the cost is authorized.
 
For contractor comparisons, insist that exclusions sit beside the price rather than in vague notes. Useful line items include demolition and disposal, protection of retained areas, patching after electrical or plumbing work, permit costs, inspection delays, cleanup, and temporary kitchen or bathroom arrangements. Austin timing should be confirmed against the actual permit scope; don’t let anyone build the programme around an unverified approval date.
 
Following Katarina’s sequencing point: I would not set the demolition date merely because a contract is signed. First confirm measured dimensions, product selections, expected delivery windows and where materials can be stored safely. Then map which bathroom remains usable while the other is open. In a compact five-bedroom house, keeping one functioning route through the home may matter as much as trade efficiency.
 
If the full $171,400 is assigned before demolition starts, one concealed defect could force a rushed cut elsewhere. I would recast the budget as firm scope, provisional allowances and money that remains untouched for surprises.

Send that same breakdown and the same inspection findings to every bidder, then request a programme showing selection and ordering deadlines. If sensible allowances leave nothing in reserve, postpone flooring, paint or another cosmetic item rather than counting on the hidden work being cheaper than expected.
