Frequently Asked Questions - Construction in Mountain View, CA
We've been building and remodeling across Mountain View and the Peninsula since 2007. Here are the questions we hear most often, answered with the specifics you'd ask for if we were standing in your driveway.
Pricing & Cost FAQs
A typical home addition in Mountain View runs between $350 and $550 per square foot, with most projects landing in the $150,000-$400,000 range depending on foundation work, roofing tie-ins, and whether you're extending into a second story. Mountain View's older neighborhoods like Old Mountain View and Monta Loma often need seismic upgrades that newer developments don't, which adds $8,000-$15,000 to the foundation budget. We quote every addition with a fixed price and written scope before we pull the first permit. Call (669) 215-4852 for a free written estimate on your specific project.
Mountain View kitchen remodels typically range from $85,000 for a mid-range update to $180,000 for a full gut with layout changes, which tracks slightly below Los Altos Hills and Atherton but above Santa Clara and Newark due to permit complexity. Mountain View's building department requires more detailed electrical and plumbing plans than Santa Clara County's unincorporated areas, adding roughly 10-15% to permitting costs. We itemize every line in our quotes so you see where the money goes before you commit. Call (669) 215-4852 to schedule your free estimate.
Quotes vary because contractors often price different scopes, not the same job. One quote might assume you'll keep existing drywall; another prices full replacement. One includes permit fees; another treats them as your problem. Our Haven Standard, Clause 1, requires a written scope with every price, so you know exactly what's included. We also document what we found during site assessment with photos, so there's no guessing. The price we write is the price you pay, with change orders signed before any extra work begins.
Hidden costs usually come from surprises underground or inside walls, not from us. In Mountain View's Cuesta Park neighborhood, we've found deteriorated clay sewer lines that needed replacement before foundation work could proceed. In the San Antonio area, older homes often have unpermitted additions that must be brought to code. We build a contingency line into every quote, typically 5-8%, and we flag likely risks during our initial walkthrough. Nothing gets added to your bill without a signed change order first. That's Haven Standard, Clause 5: no surprises.
Mountain View building permit fees typically run 1.5-2.5% of total construction value, with a minimum fee around $1,200 for smaller projects. Plan check fees add another $800-$1,500, and trade permits for electrical, plumbing, and mechanical each carry separate fees. The city requires Title 24 energy calculations and, in many zones, bird-safe glazing documentation. We pull all permits and manage plan check revisions as part of our project management. The permit costs appear as a line item in your written quote, not a surprise later.
Service & Process FAQs
We walk the property with you, take measurements, photos, and notes on existing conditions, and ask how you actually use the space. Within 48 hours, you'll receive a written summary of what we found, a preliminary scope, and a price range. If you move forward, we produce detailed construction drawings, handle Mountain View plan check submittal, and schedule a pre-construction meeting where we introduce your project lead and set the weekly communication rhythm. You'll get a named contact, a real schedule window, and text notifications when crews are en route. That's Haven Standard, Clause 2: arrive on schedule.
A kitchen remodel takes 10-14 weeks from permit approval to final inspection. A full home addition runs 6-9 months. Mountain View's plan check timeline is currently 4-6 weeks for residential projects, which we build into our scheduling. Weather rarely delays interior work, but winter rains can push exterior framing in January and February. We don't promise impossible timelines to win the job. Every contract includes a written completion window, and we update you weekly if anything shifts. We've delivered over 4,000 projects since 2007 with documented records of when we started and when we finished.
We work both ways. For smaller projects, our in-house design team produces permit-ready plans, which saves you architect fees of $8,000-$15,000. For complex additions or homes in Mountain View's R1-H historic zones, we partner with local architects who know the city's design review board. Either way, we manage the entire process: design, engineering, permit submission, and construction. You don't coordinate between separate firms. The price in your quote covers everything we've agreed to deliver.
We regularly build in Old Mountain View, Monta Loma, Cuesta Park, Blossom Valley, and the San Antonio area. Each has distinct construction realities. Monta Loma homes from the 1950s often need electrical service upgrades from 100 to 200 amps. Old Mountain View's smaller lots require creative setback solutions. Blossom Valley's newer homes have HOA design guidelines we navigate during planning. This local knowledge means we spot issues early and price them accurately, not discover them halfway through demolition.
For kitchen remodels, most Mountain View homeowners set up a temporary kitchen in the garage or a spare room and stay put. For whole-home renovations or additions affecting multiple bathrooms, we typically recommend moving out for 6-10 weeks. We've coordinated temporary housing referrals for clients in Los Altos Hills and Palo Alto who didn't want the dust and noise. We seal work areas with ZipWall barriers and run HEPA filtration to minimize disruption. Your project lead will tell you honestly whether staying is realistic for your specific scope.
Brands & Parts FAQs
We specify windows based on your home's exposure, budget, and Mountain View's Title 24 requirements. For coastal exposure homes in Menlo Park and Atherton, we often recommend ES Windows for their impact-rated vinyl frames and thermal performance. For modern builds in Mountain View's North Bayshore area, ECO Window Systems provides the thin sightlines and U-factors that meet strict energy codes. For traditional homes in Los Altos and Los Altos Hills, CWS offers divided-light profiles that match existing architecture. Every window spec includes the NFRC rating, installation method, and warranty terms in writing before you approve.
Homes near Highway 101, the 85 corridor, or Caltrain lines in Mountain View and Sunnyvale benefit from laminated glass with an acoustic interlayer. Mr-Glass supplies laminated units that reduce exterior noise by 8-12 decibels compared to standard dual-pane windows. For a home we recently worked on near Castro Street, the combination of laminated glass and proper installation detailing dropped interior noise from 62 dB to 48 dB, which the owner described as the difference between "living next to the highway and living near it." We measure actual noise levels during site assessment and specify glass accordingly.
You choose from options we pre-qualify. We present 2-3 selections per category, flooring to fixtures, that we've verified are in stock, meet code, and perform well in our climate. This prevents the three-month delay of backordered tile or the nightmare of discovering your selected countertop cracks in direct sun. If you have a specific material in mind, we'll vet it for availability, warranty support, and suitability. The final selections are written into your scope with model numbers, so there's no substitution without approval.
Licensing & Insurance FAQs
Is Rowan Construction Group licensed to work in Mountain View?
Every pro working under our name is required to hold the California contractor's license and insurance the state requires, with license numbers documented on your contract. Mountain View requires all contractors to register with the city and carry minimum $1 million general liability coverage. We maintain active registration and provide certificates of insurance naming you as additional insured upon request. Haven's Verified Crews standard, Clause 3, means background checks and license verification are conditions of working under our brand, not promises we make after the fact.
What insurance should we verify before hiring any Mountain View contractor?
Require general liability, workers' compensation, and a commercial auto policy. Ask for certificates naming you as additional insured, not just a policy summary. Verify the license number on CSLB's website, and check that it matches the company you're contracting with, not a borrowed or expired number. We provide all documentation before you sign, not after you ask. If a contractor hesitates, that's information worth acting on.
Do you pull permits, or is that our responsibility?
We pull every permit required for your project and manage plan check responses, revisions, and inspections. Mountain View requires separate permits for building, electrical, plumbing, and mechanical trades, plus a demolition permit if we're removing load-bearing elements. We schedule inspections in sequence so no work proceeds without proper sign-off. You receive copies of every approved permit and inspection card for your records. This is standard in our process, not an add-on service.
Emergency & Response FAQs
True emergencies involve structural compromise, active water intrusion, or safety hazards: a failed retaining wall, a roof deck leak flooding interior space, or compromised framing after a vehicle impact. We take these calls during our operating hours, Monday through Friday 7:00 AM - 8:00 PM, Saturday and Sunday 7:30 AM - 8:00 PM, and dispatch for temporary stabilization the same day when possible. For after-hours structural emergencies, we recommend contacting Mountain View Fire Department for immediate safety assessment, then calling us first thing in the morning for repair planning. We do not claim 24/7 availability because honest scheduling beats broken promises.
Our lead time is typically 4-8 weeks from signed contract to first day on site, depending on permit status and trade availability. If you already have approved permits and engineered plans, we can sometimes start within 2-3 weeks. Mountain View's plan check queue moves faster than Palo Alto's but slower than Santa Clara's. We don't inflate urgency to pressure a signature, and we don't accept deposits for work we can't schedule. Your written contract includes a start-by date with remedies if we miss it.
Yes. Our service area includes Los Altos, Los Altos Hills, Sunnyvale, Palo Alto, Stanford, Cupertino, Santa Clara, Menlo Park, Newark, Atherton, and Saratoga. Each city has different permit requirements, inspection schedules, and design guidelines. Our project managers know which Mountain View-adjacent jurisdictions accept reciprocal plan check and which require separate engineering. This regional knowledge saves weeks on projects near city boundaries, like the Mountain View-Los Altos border or the Sunnyvale-Cupertino line.
Warranty & Guarantees FAQs
Our workmanship warranty covers defects in installation for one year, with structural elements warranted for ten years. Manufacturer warranties on windows, roofing, and fixtures pass through to you with registration assistance. The Haven Standard requires that every warranty term is written, not verbal, and included in your project documentation. If something fails, we document what we found with photos, repair or replace it, and add the record to your project file. Since 2007, every one of our 4,000+ projects has left with this documentation.
Call us. We answer during business hours, Monday through Friday 7:00 AM - 8:00 PM, Saturday and Sunday 7:30 AM - 8:00 PM, and schedule a site visit within one week for warranty items. For non-warranty issues, we diagnose the problem, photograph what we found, and quote any repair before starting work. We don't disappear after final payment. Our documentation system means we know exactly what was installed, by whom, and when, which resolves most issues faster than starting from scratch.
Only if you request changes and sign a change order first. Haven Standard, Clause 1, is explicit: no work proceeds on a change until the change order is signed. This is why our projects finish within a few percent of the original quote. If we encounter concealed conditions, like the deteriorated sewer lines we sometimes find in Monta Loma's 1950s slabs, we stop, photograph, explain, and quote the repair. You approve before we continue. The alternative, padding every quote for worst-case scenarios, means you overpay on nine jobs to cover one surprise. Our method is fairer and more precise.
Evidence. Haven Standard, Clause 4, requires photos and readings of what we actually found and what we installed. You'll receive a project closeout folder with before/during/after photos, inspection sign-off cards, manufacturer warranty registrations, and an as-built drawing showing any field changes. For energy-related work, we include blower door and duct leakage test results. This documentation protects your investment, supports future resale, and proves we did what we said we'd do. It's not trust us, it's show you.
