Groundline Assessments
Groundline Book a walk

Every system. Every crack. Priced.

We survey every visible system in older New York buildings and give your board a ten-year repair plan with a cost and a year on every line. Fewer surprises at budget time.

Why New York is different

Old roofs. Tight blocks. A city that inspects.

Tanks, parapets, cornices and steam plants age on a schedule nobody wrote down. We write it down.

One finding.
Shown the way you’ll get it.

Every issue gets a photo, a marked-up location, a rating and a price. Your facilities team can act on it Monday. Your board can understand it in ten seconds.

Spalled brick and open joints, north wall

What we sawBrick faces have popped off across the bay. Mortar has washed out of the joints, so water now gets into the wall.
Why it mattersLoose brick over a sidewalk is a safety issue. We flagged it to the owner the same day, and it will come up at the next facade inspection.
ActionCut out and replace failed brick, repoint the bay, check the lintels above.

One scale. Used on every line.

A rating means the same thing on the roof as in the boiler room, so you can compare a $12,000 item against a $180,000 one and decide what goes first.

Good

Working as designed. Routine upkeep only. More than half its expected life remains.

Fair

Showing wear. Plan for repair or replacement within the ten-year window.

Poor

Failing or near the end of its life. Budget for it in the next one to three years.

Immediate

A safety, code or water-damage risk. We tell you the same day, not in the report.

Priority 1

Priority 2

Keeps water and weather out

Priority 3

How we’re different.

Most assessments end at a list of problems. Ours ends at a plan your board can act on.

Format

Typical: A long PDF that gets filed and forgotten.

Groundline: A two-page summary up front. The detail sits behind it for the people who fix things.

Findings

Typical: Paragraphs of text, a few small photos.

Groundline: One plate per issue: photo, location, rating, action and cost.

Cost

Typical: A lump sum, or a range with no year.

Groundline: A cost and a year on every line, in today’s dollars and escalated.

The plan

Typical: A fixed document the day it is printed.

Groundline: A live spreadsheet you can sort and update as work gets done.

New York

Typical: A generic checklist from somewhere else.

Groundline: Built around the city’s own inspection cycles, so the plan lines up with your filings.

Price

Typical: Hourly, or open-ended until it is done.

Groundline: One fixed fee for a written scope.

Next step

Typical: Findings only. Pricing the work is your problem.

Groundline: Scopes written clearly enough to send to any contractor for a bid.

Example Positioning copy for illustration.

The city runs on cycles. So does your plan.

New York buildings carry their own inspection clocks. We line your plan up with them. The inspections and filings themselves are done by the licensed professionals and owners each law names.

Local Law 11

Facade

Every 5 years for buildings over six stories. Repairs found here often drive the biggest line in a plan.

Local Law 152

Gas piping

Every 4 years, scheduled by community district. We note when yours falls.

Local Law 87

Energy audit

Every 10 years for large buildings. Our findings cover the same systems.

Local Law 97

Carbon limits

Yearly limits for larger buildings. We flag heating and lighting upgrades worth timing with planned replacements.

What we ask of you

Drawings and past reports if you have them, and access to roofs, cellars and mechanical rooms.

What we do not do

We do not open walls, test equipment or give structural engineering opinions. What we cannot see, we flag rather than guess.

What sets the fee.

Each proposal has one fixed price for a written scope. These six things affect the price. Published prices from other firms show the range.

Your priceOne fixed fee for a written scopeNo hourly billing. Nothing added after the walk.
  1. Floor area

    More square feet means more days on site.

    Biggest driver

    Published exampleOne architect's flat fees: $1,500 under 5,000 sq ft, $2,500 up to 15,000, $4,000 up to 50,000.

  2. Building age

    Older buildings have more hidden history to review.

    Can add

    Published exampleOne inspector adds $50 per 2,500 sq ft for buildings built before 1950.

  3. Systems in scope

    A shell-only survey costs less than a full look at heating, plumbing and electric. The price includes anything that needs an engineer's opinion.

    Can add

    Published exampleNo firm we checked lists a price for each system. The proposal sets the price.

  4. Extra reports

    A cost-to-fix list, a long-range capital plan or an accessibility review each adds work.

    Can add

    Published exampleOne inspector: capital forecast +3 cents per sq ft ($300 minimum), cost-to-fix +2 cents ($250 minimum). One architect: accessibility review $1,200 to $2,000.

  5. Several buildings

    Visiting several buildings in one trip can lower the price for each.

    Can lower

    Published exampleOne firm: $1,200 to $2,000 per property in a group, compared with $1,500 to $2,500 for one.

  6. Yearly refresh

    Updating a plan costs less than starting over.

    Can lower

    Published exampleOne reserve study firm: an update with a site visit is 50% to 80% of a full study, and 25% to 50% without one.

Priced in your proposal Access (roof hatches, locked rooms, occupied spaces), rush dates, reliance letters for lenders, and travel. None of the firms we checked lists a set price for these. One bills travel at cost.

What we need for a price

  • Address and number of buildings
  • Floor area
  • Year built
  • Systems in scope
  • Your deadline
  • Who will rely on the report

These are other firms' published prices, checked October 26, 2026. Scopes differ, so use them as a rough guide. Sources: M. J. DeVere, Architect · Hill Property Inspections · Envicon Group · Association Reserves

Questions boards ask.

How is this different from the city facade inspection?

A facade inspection covers the exterior walls for a city filing. A condition assessment covers every system in the building and turns it into a priced, multi-year plan. We note where your facade cycle stands. The facade inspection itself is done by the licensed inspector the law requires.

Will you disrupt classes or residents?

We schedule the walk around your calendar. For schools that often means early mornings, weekends or breaks. Occupied rooms are entered only with your staff.

Do you open walls or test equipment?

No. The assessment is visual and non-destructive. Where something can’t be judged by sight, we say so and recommend the right specialist test.

How accurate are the costs?

They are planning estimates for budgets, not contractor bids. Each one is shown in today’s dollars and escalated to the year the work is planned.

What happens after the report?

You keep the spreadsheet and update it as work gets done. We also offer a short yearly refresh so the plan stays current.

The details a board asks for.

The rules and prices here are researched, with a link to each source, checked October 25, 2026. Lines tagged “Sample firm detail” are made up, because Groundline is an example firm.

People and credentials

Who may legally do this work in New York.

  • Licensed engineer or architect
  • City-approved facade inspector
  • Loan rule: 5+ years in the field

Sample firm detail A principal who is a New York licensed engineer or architect, a field assessor and a cost estimator. Names, license numbers and years of experience go here. Check any license number with the state before you hire.

Sources and detail

In New York, only a licensed engineer or architect may practice those professions or use the title. The law counts consulting, investigation and evaluation that protects people and property. A city facade inspection must be done by an exterior wall inspector the Department of Buildings has approved. A parking garage inspection needs a licensed engineer approved for it. Freddie Mac, which buys apartment loans from lenders, wants the consultant to have a related degree, five or more years in the field, and three or more years of apartment-building inspections.

Insurance

What coverage to ask for before you hire.

  • Workers' comp for most employers
  • City contracts: $1M liability minimum
  • Loan rule: original certificate

Sample firm detail Professional liability, general liability and workers’ compensation. Carrier and limits go here. A certificate is sent on request.

Sources and detail

Most New York employers must carry workers’ compensation. City contracts set insurance in each contract, and the city’s procurement office says general liability must be at least $1,000,000. Freddie Mac, which buys apartment loans from lenders, makes the consultant hand over an original certificate of insurance.

Sources: NY Workers’ Compensation Board · NYC DCAS procurement FAQ · Freddie Mac Guide §62.8

Scope and limits

A walk-through survey, not a full test.

  • Representative sample
  • Findings as of the visit day
  • Costs are estimates, not bids

Sample firm detail Anything we could not see, such as locked rooms and areas behind finishes, is listed as not observed instead of guessed.

Sources and detail

The standard behind these reports (ASTM E2018-24) is built on a walk-through of the building. It looks at a representative sample and can extend what it sees to similar areas. It is not technically exhaustive and cannot remove all uncertainty. Findings reflect the day of the survey. Cost figures are opinions of what a fix might cost, not bids. Freddie Mac also has the consultant review maintenance records and elevator, boiler and safety certificates.

Sources: ASTM E2018-24 · Freddie Mac Guide §62.4

Pricing

Published fees start around $1,500.

  • $1,500 under 5,000 sq ft
  • $4,000 for 15,000 to 50,000 sq ft
  • Reserve studies: $10,000 to $40,000

Sample firm detail One fixed fee, quoted after a scope call. No hourly billing.

Sources and detail

Published fees for a basic condition assessment run from $1,500 for a building under 5,000 sq ft to $15,000 and up for the largest. One architect lists $4,000 for 15,000 to 50,000 sq ft. Another firm’s 2025 guide says $5,000 to $10,000 for 50,000 to 200,000 sq ft. In 2023 a New York property manager told a news site a co-op or condo reserve study, a broader service than a basic assessment, costs $10,000 to $40,000. These are firm web pages and one interview, and scopes differ, so use them as a rough guide only.

Timing

Reports usually arrive 2 to 3 weeks after the visit.

  • Site visit: 1 to 3 days
  • Report: 2 to 3 weeks later
  • Loan rule: report within 6 months

Sample firm detail A reply in one business day, a site walk within two weeks, and the summary three weeks after the walk.

Sources and detail

Published guides put the report two to three weeks after the site visit, and the visit itself at one to three days. One architect’s price page says 10 to 15 business days after the inspection. Loan rules add dates: Freddie Mac wants the report dated within six months before the loan package is sent, and the site visit within 30 days before the report date.

Sources: M2E guide, 2025 · M. J. DeVere, Architect · Freddie Mac Guide §62.3

Who may rely on the report

The contract says who may rely on the report.

  • The parties who sign
  • Others only by agreement
  • Lenders decide for themselves

Sample firm detail The owner who hires us may rely on the report. Lenders and buyers get a reliance letter on request, written by counsel. No consultant can promise a lender will accept a report.

Sources and detail

The standard for these reports (ASTM E2018-24) says they are usually for the parties who sign the contract. Others may rely on a report only by agreement, and only as of the day of the visit. Loan rules spell it out: Freddie Mac requires a set statement in the report that names the lender and other listed parties. A lender also decides for itself whether the report and the building are acceptable, and it can add requirements.

Sources: ASTM E2018-24 · Freddie Mac Guide §§62.3, 62.7

Sample report

See the format before you hire.

  • Photo, rating and price
  • Ten-year plan
  • Spreadsheet cost table

Sample firm detail A full sample would be a PDF of these same parts for an invented building.

More detail

The page already shows the parts: one finding with a photo, a rating and a price, the rating scale, the ten-year plan, and the table of largest items. Download that cost table as a spreadsheet to see the format.

Service area

Five boroughs, five counties.

  • Bronx
  • Brooklyn
  • Manhattan
  • Queens
  • Staten Island

Sample firm detail All five boroughs. Nearby counties by request.

Sources and detail

New York City has five boroughs, and each is also a county: the Bronx (Bronx County), Brooklyn (Kings), Manhattan (New York), Queens (Queens) and Staten Island (Richmond). The city facade law covers buildings higher than six stories, and the inspection comes around every five years.
