11-Month Warranty Inspection in San Marcos, CA

A year goes quickly after you pick up the keys to a brand-new home, and San Marcos owners are often surprised how much their builder still owes them right up until the twelve-month mark. The first-year warranty covers workmanship and a long list of components, but only the defects you put in writing get repaired on the builder's dime. Once that window shuts, the same items land on your invoice instead.

An 11-month warranty inspection is a complete inspection scheduled for month ten or eleven, while the builder is still obligated to fix what shows up. The scope matches a standard buyer's inspection — roof, attic, framing, electrical, plumbing, HVAC, grading, and finishes — but it is written to flag the items a builder has to warrant, with the photos and locations their warranty department can act on. Across San Marcos we run these constantly in the newer hillside communities — San Elijo Hills, the University District near CSUSM, the Rancho Coronado and Discovery Hills phases, and the master-planned tracts climbing the grades off Twin Oaks Valley. This page walks through what the inspection documents, the San Marcos conditions that surface first-year defects, what we routinely find, how the report runs, and where our scope stops.

What does an 11-month warranty inspection cover on a new San Marcos home?

This is the full house, not a quick punch-list lap. We inspect every accessible system the way we would for a buyer, then frame each finding so it lines up with what the builder agreed to warrant for the first year. On a year-old San Marcos home that means:

• Roof and attic — tile or composition covering for slipped, cracked, or under-fastened pieces, flashing at penetrations, plus attic insulation depth and ventilation that may have been installed short on a fast-moving tract.
• Framing and finishes — drywall cracks at corners and seams, nail pops, separating base and crown, and door or window reveals that shifted as the house took its first season of movement on hillside fill.
• Electrical — panel labeling, GFCI and AFCI protection, grounding, and the loose fixtures, switches, and outlets a rushed builder walkthrough skips.
• Plumbing — fixtures, supply and drain connections, water-heater operation and seismic strapping, and any slow weeping under vanities or at hose bibs.
• HVAC — heating and cooling in operation, room-to-room balance, duct connections, and condensate handling after a system that ran hard through a hot inland summer.
• Exterior and lot — stucco cracking, weep-screed clearance, sealant at windows, and grading that should carry the first rains away from the foundation rather than toward it.

Each item gets a location, a plain-language description, and a photo in your HomeGauge report. We record observed condition only — we do not bid or perform the repairs we list.

Why does a year-old San Marcos build surface warranty items?

A new house keeps reacting to its lot and its climate long after closing, and San Marcos hands those first-year reactions a few local accelerators. Timing the inspection here is worth it precisely because of what this terrain does to a twelve-month-old home:

• Expansive clay soils: Large stretches of San Marcos sit on expansive clay that swells in the wet season and shrinks through the dry months. A first-year home riding that movement shows it as drywall cracks, sticking doors, and hairline stucco separations — classic items a builder repairs while coverage holds.
• Hillside cut-and-fill pads: Communities like San Elijo Hills and the University District climb steep grades on engineered cut-and-fill lots. Settlement at the fill, plus drainage and flatwork that didn't carry the first storms away, is one of the most common first-year findings on these slopes.
• Inland heat cycling: San Marcos runs a long, hot inland summer that bakes south and west walls and pushes a brand-new AC system for months. That cycling opens caulk joints, stresses the roof covering, and exposes any duct or sizing shortcut from the build.
• Tenant-occupied CSUSM rentals: A lot of newer San Marcos homes near the university get rented to students the day they close. Hard first-year use can mask or worsen builder defects, so an owner-ordered inspection separates wear from genuine warranty items before the deadline.

Which defects do we routinely catch before the San Marcos warranty closes?

Across the year-old San Marcos homes we document, the same defects come up again and again — most look cosmetic but are squarely the builder's to repair, and a few matter more than they appear. Knowing the pattern keeps you from leaving real money behind when coverage lapses:

• Settlement cracking — drywall cracks at door corners and ceiling seams, the signature of a first season on expansive San Marcos clay.
• Nail pops and seam ridging — framing shrinkage pushing fasteners back through the finish.
• Stucco hairlines and weep-screed problems — cracking at corners and windows, and screed set too close to grade or hardscape on a graded hillside lot.
• Grading that fell back toward the house — soil sloped or settled toward the foundation instead of away, a genuine concern on San Elijo Hills and Twin Oaks Valley fill pads.
• HVAC and duct shortcuts — rooms that never hold temperature, loose or crushed flex duct, and condensate routed poorly, all obvious after a full inland cooling season.
• Roof and flashing misses — lifted tiles, exposed fasteners, and thin sealant at penetrations on a roof fresh off its first summer of heat.
• Loose finish and plumbing items — unsealed grout, drips under sinks, GFCI gaps, and fixtures left loose at the tail end of the build.

We separate normal first-year settling from a defect the builder owes you, so the list you submit is one a warranty rep takes seriously instead of brushing aside.

How does the inspection run, and what do you hand the builder?

Start by pulling your closing date — that date sets the twelve-month deadline, and you want the inspection booked with a few weeks of runway so there's time to submit the claim and let the builder schedule repairs before the window shuts. Send us the address, the builder, and the close date and we'll confirm the timing.

On site we run the entire home: up on the roof and into the attic, across every room for finish movement, at the panel and each GFCI, under sinks and at the water heater, and through the heating and cooling in operation. We read the exterior stucco, the weep screed, and the lot grading with the hillside fill and expansive clay specifically in mind. A full inspection takes the time a full inspection takes — we don't skim it just because the home is a year old.

You receive a HomeGauge report, typically same day or next day, with every finding located and photographed in language a warranty department can act on without a translator. Many San Marcos owners forward it straight to the builder as their warranty submission. The report documents condition — we don't patch drywall, re-grade lots, or perform the repairs we call out, which keeps the list objective when it lands on the builder's desk. Where a finding needs a leak pressure-test or a structural opinion, we say so plainly and coordinate or refer the right licensed specialist rather than stretch the inspection past what it is.

Why do San Marcos owners have Joseph Romeo write the report?

A warranty report only holds up if the builder can't wave it off, and that comes down to the judgment behind each call. Your inspection is performed by Joseph Romeo, an InterNACHI Certified Professional Inspector (CPI) who also holds a California CSLB General Contractor license (#1113143). On a warranty inspection that builder's-side background is the whole point — he knows how these San Marcos tracts go up and where production crews cut corners, so he can tell a cosmetic settlement crack from a grading or framing defect the builder is obligated to fix, and write it so it sticks.

• 20+ years and 10,000+ inspections across San Diego County, including the newer San Marcos communities from San Elijo Hills and the University District to the Twin Oaks Valley grades.
• 4.9 stars across 106 Google reviews from buyers, owners, and agents.
• Independent and conflict-free — he doesn't perform the repairs the report calls out, so nothing on the list is padded toward work we'd profit from; it's what the builder actually owes you.

We are InterNACHI CPI and CSLB-licensed; we are not ASHI or CREIA members, and we don't post flat prices on the page — the fee depends on the home, so check the fee schedule or send the address and we'll confirm before you book.

Which related inspections suit new San Marcos homes?

The 11-month inspection drives your warranty submission, but depending on the home and the lot a few companion inspections are worth folding into the same visit in San Marcos's newer communities:

• Sewer scope — a camera down the new lateral, where construction debris, bellies, and poor slope turn up even on a year-old home and aren't part of a standard warranty walk.
• Thermal / infrared imaging — reads hidden moisture behind a first-year stucco crack and missed insulation in the attic before coverage closes.
• Roof-focused inspection — a closer standalone read when the tile or comp roof shows fastener or flashing issues after its first hot inland summer.
• Pool and spa inspection — for new backyard pools on these hillside lots, often built under a separate warranty from the house itself.
• Full home inspection — the same whole-house scope written for a buyer if you're purchasing a San Marcos resale rather than closing out a builder warranty.

Send us the address, the builder, and your close date and we'll tell you which of these genuinely apply before you spend on any of them.
