Permits for your San Jose remodel: what's needed & how long it takes.

Reviewed July 2026. Permit timelines and processing volumes shift, so treat the figures below as planning estimates and confirm current numbers with us before you budget a start date.

Permits are one of the most confusing parts of a remodel, and one of the most important to get right. Skipping them can stall a future home sale, void insurance, and trigger costly do-overs. Here's a plain-English guide to what San Jose requires, how long it takes, and how we handle it.

When you need a permit

As a rule, any remodel that touches electrical, plumbing, structural, or layout is going to require a permit. That includes adding or moving circuits and outlets, relocating sinks or gas lines, removing or opening walls, and reconfiguring a room. Purely cosmetic work (painting, swapping fixtures in place, refacing cabinets, or replacing countertops without moving plumbing) usually doesn't. When it's a gray area, it's always cheaper to confirm up front than to fix it later.

Who pulls the permit

We do. As your licensed contractor (CSLB #1050108), we handle the paperwork, plan review, and inspection scheduling with the City of San Jose so you don't have to navigate the permit center yourself. Pulling permits in the contractor's name also keeps the responsibility, and the liability, where it belongs.

How long it takes

How long a San José permit takes depends on which path your project qualifies for. The City publishes four:

• Online permit: the City says you can download a permit for 56 types of simple projects at SJPermits.org, most with no plans. Minor kitchen and bathroom remodels on single-family homes and duplexes are among them. See which equipment swaps qualify.
• Over the counter: for qualifying projects on single-family or duplex properties, the permit is issued during your visit if the plans and documents are accurate. Properties with an open code enforcement case, or in certain flood, landslide or wildland zones, do not qualify.
• Residential Express: for qualifying single-family projects, the permit is issued during an online meeting booked up to two weeks ahead, for a fee of 1.5 times the plan review fee.
• Standard plan review: required for remodels over 750 sq ft on a one-story home, remodels of any size on a duplex or multistory home, additions over 500 sq ft, and ADUs. The City's target for an alteration with no structural calculations is 10 working days for the first review and 5 for each round after. The clock starts only once fees are paid and complete plans are uploaded. In our experience, work that needs engineering takes longer.

Review times also depend on application volume, which is exactly why we start permitting early and run it in parallel with material ordering, so construction can begin the moment you're ready instead of months later.

ADUs are the one exception to "more scope means more wait." State law puts ADU permits on a faster, ministerial review track: the Government Code sets a deadline for the City to act on a complete application, so an ADU permit often moves quicker than this general remodel estimate, not slower. See our ADUs & additions page for what that looks like in practice.

Title 24 (energy)

California's Title 24 energy code applies to most permitted remodels that involve lighting, electrical, or mechanical work. In practice that means high-efficiency LED lighting, proper ventilation, and a documented energy-compliance report submitted with your permit. We build this into the plan from the start so it's never a surprise. See our full Title 24 and SB 407 guide for the specifics.

SB 407 (plumbing fixtures)

California's SB 407 requires water-conserving toilets, showerheads and faucets in homes built on or before January 1, 1994, and replacing old fixtures can be a condition of your permit final. For those older homes it covers the whole house, not just the room being remodeled, so we flag it early and fold it into your scope and budget. Full GPF/GPM thresholds and deadlines are in the same Title 24 and SB 407 guide.

For equipment swaps, see water heater, HVAC, panel and solar permits. For outdoor structures, see shed, fence and deck permit rules.

Inspections

Permitted work is inspected at key stages: typically rough-in (before walls are closed) and final. We schedule and meet every inspection, fix anything that comes up, and don't consider the job done until it has passed and you're thrilled with the result. See how San José building inspections work.

Work already done without a permit?

Permits can also be pulled after the fact. Most cities charge extra for it, often double the normal permit fees, and the inspector may need walls opened to see the work. Our guides cover legalizing unpermitted additions, legalizing an unpermitted unit as an ADU, California's ADU amnesty, and the penalty rules by city across Santa Clara County.
