When a building permit is required

The city says permits are required for new residential and non-residential buildings, additions, remodels, repairs and changes in use. Inspection services cover those same categories, and inspections can be scheduled online. If the project involves public works construction in city streets, land use development or fire systems, additional permits apply.

Simple permits for common home projects

Santa Clara offers a Building Simple Permit for limited, like-for-like residential work on single-family homes, duplexes and ADUs. The city lists these project types:

• Like-for-like furnace, air conditioner and ductwork replacement
• Residential solar (PV) through SolarAPP+
• Re-roofing, excluding structural work
• Water re-piping, water or sewer service line replacement from the house to the property line and clean-out replacement or installation
• Like-for-like water heater replacement

Simple permits are not available for townhomes, apartment complexes or condos, and projects in historic areas, with active code enforcement cases or with other parcel conditions are not eligible. Property line clean-out work also needs an encroachment permit from Public Works.

The city says approval typically comes within one to two business days: an application that passes the automatic compliance check is issued instantly, and one flagged for review is issued within one to two business days once approved.

Fees depend on the project and are non-refundable and not credited toward a corrected application. If you are unsure which record type to use, the city advises applying for a Building Regular Permit. After the work, schedule a final inspection.

How Santa Clara inspections work

Inspections are scheduled, cancelled and checked through the Permitting Online Portal.

The city says it assigns a two-hour inspection window and sends it by email to the applicant and the designated inspection contact by 8 a.m. on the day of the inspection; it is also visible on the portal, or you can call (408) 615-2440 after 8 a.m. Someone familiar with the project has to be on site for the whole window, the inspection area must be open and free of construction debris, and the permit card and the city-approved plans, printed in color, must be on site.

Plans and the permit can be downloaded from the Documents section of the permit on the portal.

If you need an inspection outside normal hours, the city offers overtime inspections. They need approval from the Inspection Manager, carry additional fees, and require an overtime inspection application emailed to building@santaclaraca.gov. The city also says all final inspections must be scheduled for the same day, so plan the last steps of a project together rather than one trade at a time.

Final inspections, occupancy and temporary certificates

A final building inspection is required before a building can be occupied. The city warns that without occupancy approval, owners or tenants could be cited for illegal use or occupancy that violates the city code.

When a building must be used before every item is finished, the city has a Temporary Certificate of Occupancy, requested with a TCO application and subject to the current fee schedule.

For a seller, the takeaway is simple: a project with work completed but never finaled is not a finished project in the city’s eyes.

Permit expiration and extensions

Santa Clara permits are valid for 365 days from the date of issuance or from the last passed inspection. If a permit expires before the work is finished, work can start again only after a new permit is obtained.

The Building Official may extend an active permit for up to 365 days, but an extension can be given only once, and permits associated with code violation cases may not be extended. A request is made by uploading the Building Permit Extension Request form to the portal.

If you are buying or selling a house with an old, lapsed permit, ask the city what the status is before you rely on it.

Simple permit fees and limits

Fees for a Building Simple Permit depend on the project type and scope, and the city states that fees paid are non-refundable and are not credited toward a future or corrected application.

The city points applicants to the current Municipal Fee Schedule under Building, and to its list of frequently assessed fees for minor residential permits. If you are not sure which record type fits your project, the city says to apply for a Building Regular Permit instead.

Why final inspections matter to buyers

A re-roof, HVAC or water heater swap that was never finaled can show up as an open permit in a buyer’s review. Before you list, confirm that each permit on your address has a final inspection, and keep the paperwork with your records.

California disclosure rules when permits are missing

If you know of work done without a required permit, raise it with your agent or escrow officer.

Civil Code section 1102.1 keeps your duty to disclose material facts in an as-is sale and does not allow waiver of the transfer disclosure statement, and under section 1102.3 a buyer who gets a late disclosure can cancel within three days of in-person delivery or five days of mailing.

See our statewide as-is guide and our Santa Clara code enforcement guide for how open cases can affect a sale.

Natural hazard disclosure for a Santa Clara home

After permits, buyers ask about hazard zones.

California requires the seller, or the seller’s agent, to disclose whether the property is in a special flood hazard area, an area of potential flooding from dam failure, a very high fire hazard severity zone, an earthquake fault zone, a seismic hazard zone or a state responsibility wildland area.

A waiver is void, and a late disclosure can let the buyer cancel. See our natural hazard disclosure guide.

What a Santa Clara sale costs

The county documentary transfer tax is $0.55 per $500 of value or fraction, and a city with its own tax can add half that amount per $500. On a $600,000 sale the county amount is $660.

Loan payoff, escrow and title, any agreed commission and the proration of the year’s property tax come out of proceeds. Simple permit fees are non-refundable in Santa Clara, so budget carefully before you apply. Our seller closing costs guide includes a net proceeds calculator.
