Reading the Place Before the Quote

Why this matters

Two houses with the same floor plan, the same equipment and the same customer request can be two different jobs, because one sits on clay with a 42 inch frost line and hard well water and the other sits on sand in a town with a 12 inch frost line on city water. The house does not tell you which one you are standing in. The quote that ignores the place gets corrected later, either as a change order the customer resents or as labor the shop eats. Reading the place is the ten to twenty minutes of research that decides whether your first number is your real number.

What counts as a significant job

Not every call needs this. A filter change does not. A common starting point, tune it to your trades: run the place questions on any job that puts something in the ground, mounts something outside the envelope, sizes equipment to a load, or runs more than one crew-day. Those four triggers cover the jobs where the place sets a requirement: footings, trenches, outdoor units, generators, water heaters, treatment equipment, roofing, additions and decks.

The questions are cheap before the quote and expensive after it. A trench depth discovered at the inspection is a re-dig. A design temperature discovered after the install is a callback every cold snap. A rear easement discovered after the pad is poured is a move at your cost.

The place questions, and what each one changes

There are ten. Each answers a different question, comes from a different source, and changes a different part of the quote. The last column is the point of this card: it tells you whether a surprise lands on price (same work, more of it), scope (different work), product (different equipment or material) or permit (a different approval path).

Two notes on the table. The jurisdiction is the question that sets the answers to several others, because the frost depth, design temperatures, flood rules and code edition all come from whichever building department has the address, and the city name on the mailing address is not always the one that does. An unincorporated address outside town lines usually belongs to the county. Second, a question can land in two columns: a flood zone changes the scope (elevating the unit) and the permit (a floodplain review). The table names the column a surprise most often lands in, not the only one.

Which ones change the price and which change the job

The split matters because the customer conversation is different.

Price surprises are the same work in a larger quantity: a deeper trench, more concrete, more hours. They are easy to explain and easy to quote once known. They are also the ones shops most often absorb, because they feel like "part of the job" and nobody wants to re-open a signed number for a few hours of digging.

Scope surprises change what you are building. Clay that needs a wider footing, a flood elevation that puts the condenser on a platform, an easement that moves the generator to the other side of the house and adds 30 feet of gas line and conduit. These need a revised proposal, sometimes a different trade, and the customer has to agree to the new thing.

Product surprises change the equipment line. A cold-climate heat pump instead of a standard one because the design temperature is below the standard unit's useful capacity. A coated coil because the house is in the warranty's coastal zone. These belong in the first quote, because swapping them later reads as an upsell even when it is not.

Permit surprises change the timeline more than the price: a plan review, a floodplain permit, an HOA architectural approval that meets monthly. Tell the customer the calendar, not just the cost.

How deep to go, by job size

The research scales with the job. A reasonable default:

• A one-day outdoor job (condenser replacement, a pad, a hose bib): jurisdiction, frost depth if anything goes in the ground, coastal exposure, and a look at the lot for lines and easements. About ten minutes.
• A multi-day job or anything sized to a load (system replacement, water heater conversion, treatment system): all ten questions, with the design temperatures and the water data pulled from source rather than remembered.
• Anything structural, below grade, or in a mapped hazard zone (addition, deck, generator, foundation work, a flood-zone install): all ten, plus the property research checklist for large jobs and, where the soil or the flood map says so, a professional's input before the quote is final.

The failure in practice is not that shops never check. It is that they check from memory, using the frost depth or design temperature from the town where the owner learned the trade. A crew that works across two or three jurisdictions should keep a profile for each one rather than a number in someone's head. See related: The Jurisdiction Profile SOP.

A worked example

A shop is asked to replace a gas furnace and air conditioner with a heat pump, and to run a water line and a 120 V circuit 80 feet to a detached workshop. The owner of the shop learned the trade one county south, where the frost depth is 30 inches and the 99 percent heating design temperature sits in the high teens.

The research, about fifteen minutes from the office:

• Jurisdiction. The address says the city, but the parcel map shows it is outside city limits, so the county building department has it. The county adopts the IRC with a local amendment table.
• Frost depth. The county's climatic design table lists 42 inches. The water line must be below that, and the plumbing code adopted there puts exterior water piping at least 6 inches below the frost line, so the trench bottom goes to at least 48 inches, not the 30 the crew is used to.
• Design temperature. The county table lists a winter design temperature of 2 F (illustrative for this example). The standard heat pump in the shop's usual quote is rated down to about 5 F with a steep capacity drop. That forces a cold-climate unit, or the standard unit plus a larger backup heat strip.
• Water. The house is on a private well. The customer mentions white crust on the faucets. That points at hardness, which matters for the heat pump water heater the customer asked about "maybe later". Flag it, test on the visit.
• Lot lines and easements. The recorded plat shows a 10 foot utility easement along the rear line. The workshop sits 14 feet from that line, so the trench path crosses the easement for about 10 of its 80 feet. Work inside a utility easement is allowed in most cases, but the locate call matters more there because that is where the buried utilities are.
• Flood, coastal, wildfire. None mapped.

What that does to the quote, against the version the shop would have written from habit:

• Trench. From 30 inches to 48 inches is 1.6 times the depth over the same 80 feet. With hand finishing and the larger spoil pile, the crew lead estimates the trench at 6 hours instead of 4. Two hours of labor is a price change, and it goes in the first number.
• Equipment. The cold-climate unit is a product change, and the largest line in the quote. It goes in the first proposal as the recommendation, with the standard unit shown as the alternative and the backup heat it would need.
• Easement crossing. Not a cost change, but the locate ticket notes the easement section, and the proposal says the trench crosses it.
• Trench safety. At 48 inches the trench is 4 feet deep, which is the depth at which OSHA's construction excavation standard requires a safe means of egress for workers in it (29 CFR 1926.651(c)(2)). Under 5 feet a protective system can be skipped only where a competent person finds no indication of a possible cave-in (1926.652(a)(1)). The proposal does not change, but the crew plan does: a ladder or ramp in the trench, and someone deciding about the walls before anyone climbs in.

The total research took about fifteen minutes and moved three things into the first quote that would otherwise have been a change order, a callback and an inspection failure.

What would change the answer. If the parcel had been inside city limits and the city lists 36 inches, the trench goes to 42 inches, and the 6 hour estimate drops back toward 5. If the customer had been on city water, the hardness question would come from the utility's annual report instead of a test. If the rear easement had been a drainage easement with a recorded restriction on structures and trenches, the path would need the easement's own terms read, and possibly a different route.

How to tell you read the place correctly

Three checks before the quote goes out:

1. Every place-driven number has a source written next to it. "Frost 42 in, county table" can be checked by the next person. "Frost 42" cannot, and a remembered number with no source is the most common way the wrong jurisdiction's value gets in.
2. The jurisdiction is confirmed from the parcel, not the mailing address. If the two disagree, the parcel wins.
3. Each surprise is in the right column. Price changes are in the number. Product changes are in the recommendation. Scope changes are named in the proposal text. Permit changes are in the timeline you give the customer.

The failure that gets past all three is the question nobody asked because the job did not look like it needed one. A water heater swap does not look like a place job until the well water has scaled the last one shut in three years. When a job surprises you after the fact, add the question that would have caught it to your trigger list.
