Selling your San Mateo home soon? One of the simplest ways to protect your price and shorten escrow is to get ahead of buyer questions with targeted pre-list inspections. You want a smooth process, fewer surprises, and the confidence to negotiate from facts. In this guide, you’ll learn which inspections matter most in San Mateo, typical costs and timelines, how results feed your disclosure packet, and a simple plan to go from prep to “just listed” without last‑minute drama. Let’s dive in.
Why pre-list inspections matter in San Mateo
Pre-list inspections help you find issues early, set clear expectations, and back up your pricing. When you disclose known conditions with reports and estimates, buyers have fewer reasons to reopen negotiations later. In San Mateo, older sewer laterals, roof wear, and termite activity are common friction points. Addressing these upfront can reduce contingency periods and keep your sale on schedule.
California also requires sellers to disclose material facts about the property. Standard forms, such as the Transfer Disclosure Statement and the Seller Property Questionnaire, plus a Natural Hazard Disclosure report, are routine. If your home was built before 1978, expect a lead-based paint disclosure too. Having inspection findings ready makes completing these documents faster and more accurate.
The must-do inspections in San Mateo
General home inspection
A whole-house inspection covers structure, exterior, systems, interior, insulation and ventilation, and basic roof observations. In the San Mateo area, this typically costs about 400 to 800 dollars, with reports delivered in 24 to 72 hours. Common findings include aging HVAC, older wiring in very old homes, signs of water intrusion, window or flashing wear, localized wood rot, and settlement in older bungalows. Remedies range from minor repairs to moisture mitigation and foundation stabilization, with receipts and permits included in your packet.
Roof inspection
A roof specialist will assess the covering, flashings, penetrations, and attic for evidence of leaks and ventilation issues. Expect 150 to 400 dollars for a standalone roof inspection. Coastal humidity and winter storms can shorten roof life or reveal vulnerabilities. Solutions can include patching, re-flashing, and targeted repairs, or a full replacement when needed. Collect contractor estimates and permits if work proceeds.
Termite and WDO inspection
A licensed structural pest control operator checks for termites, wood decay, and conducive conditions like wood-to-soil contact. This inspection often runs 75 to 300 dollars. In San Mateo, inspectors frequently find localized drywood or subterranean activity and moisture-related decay near decks or eaves. Treatments, structural repairs, and clearance or repair reports should be documented for buyers.
Sewer lateral camera inspection
A plumber runs a camera through your private sewer lateral to check for blockages, root intrusion, breaks, or misaligned joints. Budget 250 to 700 dollars depending on access and length. Many Peninsula homes have older laterals that can become high-cost escrow issues. Some Bay Area cities require certification or repair at sale. Confirm current City of San Mateo rules before listing, and consider repairing or offering a credit with estimates in hand.
Permit and records review
Pull your property’s permit history and compare it to what is present today. Unpermitted work must be disclosed and may require retroactive permits or remediation. Check with the City of San Mateo Building Division for city properties or San Mateo County for unincorporated areas. This step helps you decide whether to permit work now or disclose and price accordingly.
How inspections speed your sale
When you publish a clean, complete disclosure packet, buyers can shorten or waive certain contingencies because key issues are already quantified. That often reduces the risk of last-minute price cuts triggered by unknowns. In practice, the best results come from combining inspection reports with repair receipts and permits, plus clear estimates for any items you choose not to fix.
A simple pre-list timeline
Use the following plan 4 to 6 weeks before you intend to hit the market. Adjust based on scope and contractor availability.
- Week 1: Hire your listing agent and set inspection scope. For older Peninsula homes, prioritize general, WDO, roof, and sewer lateral. Order the Natural Hazard Disclosure report as part of your packet.
- Days 3 to 5: Receive inspection reports. Review for safety, structural issues, and major system failures.
- Week 2: Get written estimates from licensed contractors. Include permitting where required.
- Weeks 2 to 3: Decide your approach.
- Complete major safety or structural repairs and collect receipts and permit signoffs.
- Tackle easy fixes like roof flashings or water heater strapping and disclose the rest with estimates.
- Price accordingly and offer credits or an escrow holdback for larger items like lateral replacement.
- Weeks 3 to 4: Assemble your disclosure packet: TDS, SPQ, NHD, WDO, sewer camera, roof and general inspections, permit records, receipts, and HOA docs if applicable.
- Week 4+: Launch with inspection summaries available to buyers. Market the home as pre-inspected to help expedite due diligence.
Typical full prep takes 3 to 6 weeks, longer if major permits are needed and shorter if your contractor schedule is flexible.
What it costs in San Mateo
- General home inspection: about 400 to 800 dollars
- Roof inspection: about 150 to 400 dollars
- Termite/WDO inspection: about 75 to 300 dollars
- Sewer lateral camera: about 250 to 700 dollars
- Repairs and permits: vary from a few hundred dollars for minor fixes to 5,000 to 25,000 dollars or more for full lateral or major structural work
Your choices after inspections usually fall into three paths: fix major safety or structural issues, fix easy visible items and disclose the rest, or offer pricing credits backed by written estimates. In every case, documentation builds trust and reduces renegotiation risk.
Build a rock-solid disclosure packet
A complete packet helps buyers write stronger offers with fewer contingencies. Assemble:
- Transfer Disclosure Statement and Seller Property Questionnaire
- Natural Hazard Disclosure report
- General, roof, termite/WDO, and sewer camera reports
- Repair receipts, contractor invoices, and permit signoffs
- HOA documents if applicable
- Tax or assessment information, including any special district taxes where relevant
- Manuals, warranties, and receipts for major systems
Make sure to verify any city or county requirements that may apply to your sale. Requirements change, so checking the City of San Mateo and San Mateo County resources before listing is smart.
How to vet inspectors and contractors
- General inspectors: look for ASHI or InterNACHI experience and Bay Area references. Confirm insurance.
- Termite/WDO: use a company licensed by the California Structural Pest Control Board and ask for standard state reporting forms.
- Sewer lateral: hire a CSLB-licensed plumbing contractor experienced with camera inspections and clear written reports.
- Contractors: verify CSLB licenses, insurance, and local references. Confirm they will pull required permits and obtain final inspections.
Keep copies of license numbers and verification records in your file. This makes buyers more confident in the quality of work.
