Your home inspection under Form 35

Form 35 makes your purchase conditioned on your satisfaction with inspections you order, and it gives you a fixed number of days to act. This guide explains how the Inspection Period is counted, the four notices you can give on Form 35R and what silence means, how to choose inspectors, what a Washington home inspection covers and does not, and how the repair negotiation is structured.

The first days after mutual acceptance: the Inspection Period is the number of days written in Form 35 paragraph 3 (10 if the blank is empty), counted from mutual acceptance, and every option you have must be exercised by written notice before it ends.

Forms and documents that govern this step

  • Form 35 — Inspection Addendum to Purchase and Sale Agreement
  • Form 35R — Inspection Response for Form 35
  • Form 21 — General Terms k (Notices) and l (Computation of Time)
  • Form 22S / 22S-King — Septic Addendum (referenced by Form 35 paragraph 9 when the property is on an on-site sewage system)

The Inspection Period: the days written on Form 35

Form 35, the Inspection Addendum, makes your contract conditioned on your subjective satisfaction with inspections of the property. Paragraph 3 sets the Inspection Period: the number of days written on the form after mutual acceptance, 10 days if the blank is empty. That number is counted under Form 21 General Term l. The period starts the day after mutual acceptance and ends at 9:00 p.m. on the last day. A period longer than 5 days counts calendar days and rolls to the next business day only if the last day falls on a Saturday, Sunday or legal holiday. Your agent and our transaction administrator compute the exact deadline the day the contract goes mutual.

Paragraph 2 puts the inspection in your hands: all inspections are ordered by you, performed by inspectors of your choice, and completed at your expense. You may not alter the property without the seller's permission, you must restore anything an inspection disturbs, and you are responsible for damage an inspection causes.

Book the general inspection within the first two or three days. The report typically arrives the same day or the next, and if it recommends a specialist you need time inside the window to act on it, either by scheduling the specialist or by giving notice of additional inspections, described below.

Your four options on Form 35R, and what silence means

Before the Inspection Period ends you give the seller one of four notices, usually on Form 35R. The first three need only one buyer's signature; a repair request is a proposal all buyers sign.

Paragraph 3 spells out the cost of doing nothing: the contingency is conclusively deemed waived and the seller has no obligation to make repairs or modifications. Missing the deadline by an hour equals approving the inspection. The 9:00 p.m. cutoff and the delivery rules in Form 21 General Term k (a notice to the seller counts only when received by the seller or the listing side) are why your agent will ask you to sign early on the last day.

  • Approve the inspection and waive the contingency. The contract proceeds as written.
  • Disapprove the inspection and terminate. The Earnest Money is refunded to you.
  • Give notice of additional inspections. Under paragraph 5, if an inspector recommends further evaluation (a sewer scope, a roofer, an engineer, a septic specialist), you give written notice before the period expires, with the inspector's recommendation if the seller requested it. The Inspection Period then expires the days written in paragraph 5 after your notice, 5 if blank.
  • Request repairs or modifications, including a price adjustment or a repair credit. This opens the paragraph 6 negotiation, covered in the last section.

Choosing inspectors, and what a Washington home inspection covers

Form 35 paragraph 1 requires your general home inspection to be performed by you or by a person licensed under RCW 18.280, Washington's home inspector licensing law, administered by the Department of Licensing. Check the license number on the DOL site. Beyond the license, choose on experience with the housing type (a 1960s Bellevue rambler, a 2005 Issaquah Highlands townhome and a downtown Kirkland condo are different inspections), on report quality (photos, plain-language summaries, clear severity ratings), and on availability inside your window. Your agent can name inspectors RexMont clients have used; the choice and the contract with the inspector are yours.

A Washington home inspection is a visual, non-invasive examination of readily accessible systems and components, performed to the standards of practice in WAC 308-408C. Expect the inspector to cover the roof (from the ground, a ladder or a drone), exterior and site grading, structure and foundation as visible from the crawl space and attic, the electrical panel and a sample of outlets, plumbing supply and drains, the water heater, heating and cooling equipment, interior surfaces, windows and doors, insulation and ventilation, and the attached garage.

Plan to be there for the last half hour. The walk-through summary, with the inspector pointing at the things that matter, is worth more than the PDF.

What it does not cover: sewer, septic, pests and specialists

The standards also define what a home inspection is not. The inspector does not move furniture, open walls, test for mold, asbestos, radon or lead, evaluate code compliance, operate systems that are shut down, inspect underground piping or tanks, or predict remaining life. Several items Eastside buyers care about are separate inspections by separate specialists:

  • Sewer scope. Form 35 paragraph 1(a) says your inspection may include a sewer line video inspection unless the may-not box is checked. A camera runs from the house to the city main or the septic tank; the general inspector cannot see that pipe. Older Seattle, Kirkland and Bellevue side sewers in concrete, clay or Orangeburg are why this is routine.
  • Septic. Form 35 paragraph 9 advises that on-site sewage systems are outside Form 35 and points to Form 22S (Form 22S-King in King County). The septic inspection is a separate contingency with its own clock.
  • Pests. Wood-destroying organism inspections require a structural pest inspector license from the Washington State Department of Agriculture. Many home inspectors hold both licenses; the report says whether a WDO inspection was performed.
  • Specialists. Roofers, electricians, HVAC technicians, chimney inspectors (Level 2 camera), structural or geotechnical engineers, and oil tank locators. Form 35 paragraph 8 limits tank inspections to presence or absence unless the parties agree otherwise in writing.

Repair negotiations, the report rule, and the seller's response

If you request repairs or modifications, paragraph 6 governs the negotiation. The seller has the days written in 6(a), 3 if blank, to agree to all, some or none, or counter. If the seller does not agree to everything, you have the days in 6(b), 3 if blank, from the seller's response (or from the end of the seller's period if the seller is silent) to accept, agree on other remedies, or terminate with your earnest money refunded. The form warns in capitals: these periods do not repeat, and your inaction during your reply period waives the contingency. Both 3-day periods are business days under Form 21 General Term l.

Paragraph 4 surprises buyers: you shall not give the inspection report, or any portion of it, to the seller unless the seller requests it in writing; if you do, the contingency is conclusively deemed waived. You may describe the repairs you want and attach contractor bids. Checkboxes on page one of Form 35 show whether the seller asked in advance.

What to ask for, and whether a credit beats a repair, is your agent's job with you. Repairs the seller agrees to are done at the seller's expense, no fewer than the days in paragraph 7 (3 if blank) before closing, and you may pay for a re-inspection.

Your checklist

  1. 1Get the computed Inspection Period deadline from your agent or our transaction administrator the day the contract goes mutual, and calendar it with the 9:00 p.m. cutoff.
  2. 2Book a home inspector licensed under RCW 18.280 within the first two or three days; ask whether they also perform WDO (pest) inspections.
  3. 3Order the sewer scope at the same time unless Form 35 says may not, and read the septic guide if the home is on an OSS.
  4. 4Attend the last half hour of the inspection for the verbal summary, and ask the inspector what needs a specialist.
  5. 5If a specialist is recommended and time is short, have your agent deliver notice of additional inspections before the period ends.
  6. 6Decide with your agent: approve, request repairs or modifications, or terminate. Sign Form 35R early on the final day, not late.
  7. 7Do not send the inspection report to the seller or the listing agent unless the seller requested it in writing.
  8. 8If you requested repairs, calendar the seller's response deadline and your reply deadline; your reply period does not repeat.

  • We check that inspections are scheduled inside the window by the end of the second day and flag your agent if they are not.
  • We confirm each Form 35R notice is delivered the way Form 21 General Term k requires, signed and received by the listing side, and log the time.
  • We track the seller's response and your reply windows in the repair negotiation, and remind you before your reply period closes.
  • We calendar the seller's repair deadline before closing and any re-inspection you elect, and confirm completion before signing.

Questions

Common questions about your home inspection under form 35

How many days do I have for the inspection?

The number written in Form 35 paragraph 3, counted from mutual acceptance; the form's default is 10 days if the blank was left empty. Under Form 21 General Term l the period starts the day after mutual acceptance and ends at 9:00 p.m. on the last day, rolling to the next business day if it lands on a weekend or legal holiday. Your agent and our transaction administrator send you the exact date.

Should I attend the inspection?

Yes, at least for the end. Inspections typically run two to four hours; the last thirty minutes is the walk-through, where the inspector shows you what matters and what does not. You hear severity in the inspector's voice that a written report flattens. It is also when to ask which items need a specialist, so you can act before the Inspection Period ends.

The inspector recommended a sewer scope or an engineer and my window is almost over. What now?

Use Form 35 paragraph 5. Before the Inspection Period expires, your agent delivers written notice that you will conduct additional inspections, attaching the inspector's recommendation if the seller requested it. The Inspection Period then expires the number of days written in paragraph 5 after that notice, 5 if blank. Book the specialist immediately; that extension does not repeat.

Can I send the seller the inspection report to prove the repairs are needed?

Not unless the seller asked for it in writing. Form 35 paragraph 4 says providing any portion of the report without the seller's written request or consent conclusively waives the inspection contingency. You can describe the repairs and attach contractor bids on Form 35R. If the seller checked a request box on Form 35, or asks on Form 35C, then you provide what was requested.

What happens if I miss the deadline?

Form 35 paragraph 3 says the contingency is conclusively deemed waived and the seller is not obligated to make any repairs or modifications. Your ability to terminate over the inspection ends with it. The same result applies if you stay silent during your reply period in a repair negotiation. Deadlines under Form 35 end at 9:00 p.m., and the notice must be received by the listing side, not just sent.

Does the seller have to fix what the inspection finds?

No. The seller has no repair obligation unless the seller agrees to one in writing. Under Form 35 paragraph 6 the seller may agree to all, some, or none of your requests, or propose alternatives. If you do not reach written agreement, your remedy is to terminate before your reply deadline with your earnest money refunded, or to accept the property and proceed. Negotiating that outcome is your agent's job.
