Building a New Home in Almaden: House Permits, Hillsides, Trees and the City Path

Planning guide · updated November 2026

Almaden Valley sits at the south edge of San José, where valley-floor neighborhoods climb into foothill lots with oaks, creeks and wildland edges. New custom homes here almost always replace an existing house, and the City of San José — not a separate Almaden agency — issues the permits. Here is how we plan a new home in Almaden so the Single-Family House Permit, the hillside clearances, the trees and the fire rules are clear before drawings are final.

Harrod Built builds new custom homes and whole-home rebuilds across the South Bay and the Peninsula, Almaden Valley included. Own an Almaden or South San Jose lot or an older house you plan to replace, or hold a plan set that needs pricing? Phone 805-712-8993 or fill in the form at the bottom of this page.

The short answer

In Almaden Valley and the rest of San José, a new single-family home goes through the City Development Services Permit Center. Many new houses need a Single-Family House Permit from Planning before Building will issue a building permit; others go straight to Standard Plan Review when none of the City triggers apply. After Planning, plans upload through SJPermits.org and SJePlans for Building and San José Fire Department review, with Public Works clearances for grading, geologic hazards and frontage on lots that need them. (we confirm per lot)

1. Who reviews what

One City, several desks

Almaden is inside the City of San José, so every new house uses the same Development Services Permit Center as the rest of the city. The Development Services Permit Center page connects Building, Planning, Fire and Public Works; SJPermits.org online permit portal is the online front door. This is how the work splits on a new Almaden house:

Summarized from City of San José Development Services Permit Center, Standard Plan Review, Single-Family House Permit, Design Considerations, Geological Hazard Review, Preparing for Wildfire and Tree Removal Permits pages, read November 5, 2026.

Unlike Sunnyvale, San José runs its own Fire Department rather than Santa Clara County Fire, and hillside and WUI lots are common enough in Almaden that Public Works and SJFD show up early. Our Los Gatos and South Bay custom home page describes the homes we build in the South Bay, and our Sunnyvale and Cupertino permit guide cover cities next door. (we confirm per lot)

3. Design guidelines and neighborhood character

What Planning expects to see

The City’s Design Guidelines page list includes the Single-Family Design Guidelines for non-historic homes, Your Old House guidance for preserving San José homes, and the San Jose Eichler Neighborhood Design Standards. The Single-Family House Permit page points designers to those guidelines for neighborhood character and compatibility.

On a typical Almaden lot the guidelines steer scale to the street, privacy toward neighbors, garage placement, roof form and materials that fit the block. Eichler standards matter when the address sits in an adopted Eichler area; historic guidance matters when the inventory lists the house or site. We read which set applies before a concept is drawn, because the same floor plan can look very different under Eichler rules than under the general single-family guidelines.

The Design Considerations page also flags Planned Development zones, where the architectural standards of that PD and any HOA rules apply on top of the base zoning. Checking zoning and PD status on SJPermits.org online permit portal is part of the first lot review.

5. Hillsides, geology and grading

Why Almaden lots often need Public Works first

South San Jose foothill lots — including many in Almaden Valley — commonly sit near mapped geologic or seismic landslide zones, or need cut and fill that triggers a grading permit. The Geological Hazard Review page requires a Geologic Hazard Clearance from the Director of Public Works before discretionary approvals, grading or building permits when the site is in a City Geologic Hazard Zone or a State seismic landslide zone of required investigation. Lots in a State liquefaction zone need a Geologic Clearance from the City Geologist before grading or building permits.

The Design Considerations page adds that grading needs either a Grading Permit or a Notice of Exemption from Public Works, and that steeper sites follow the City’s hillside grading path rather than the flat-site path. Flood Zone A, AE, AH or AO lots follow the Building Division’s floodplain plan-set rules. We pull the address on SJPermits.org online permit portal and with Public Works early so soils, geology and grading sit on the critical path instead of arriving as a surprise after architectural drawings are done.

7. The building submittal

SJPermits.org, SJePlans and Standard Plan Review

New single-family and duplex homes must use the City’s Standard Plan Review Service page. Anyone can start the online application, but after plan approval the permit is issued only to the property owner or a licensed contractor. The steps are:

• Start at SJPermits.org online permit portal. Create an account, apply for a new permit, add the property, collaborators and scope; the system issues an application number.
• Upload to SJePlans. Only the ePlan Applicant uploads plans and answers comments. Files follow the City’s naming tool and formatting rules (separate PDFs for plan types, sub-trades and supporting documents, landscape stamp spaces, searchable text).
• Plan review. Review begins after the invoice is paid and a complete set is uploaded. Building, and often Planning, Public Works and Fire, mark comments in SJePlans; the applicant resubmits until the set is clear.
• Issuance. After final payment and any outstanding forms, staff upload the Permit Card and approved plans in SJePlans.

A soils report, structural calculations and Title 24 energy documents ride along with the drawings. Owners weighing whether to pull permits themselves can read our owner-builder comparison.

9. Before you design

Questions to answer about your Almaden lot

1. Is the lot inside San José city limits in Almaden Valley or South San Jose, and is there a current boundary and topographic survey?
2. Which zoning district applies, and does a Planned Development overlay add its own standards?
3. Does the concept trip any Single-Family House Permit trigger (height, stories, floor area ratio, creek, historic listing or large hardscape)?
4. Is the house or site on the Historic Resources Inventory, or in an Eichler area with its own standards?
5. Which trees are ordinance-size, street or heritage trees, and can the footprint keep them?
6. Is any part of the lot in a flood, geologic hazard, seismic landslide, liquefaction or WUI area?
7. Do title easements or a riparian setback narrow the buildable area?
8. What grading, driveway and sidewalk work will Public Works ask for with a new dwelling?

Owners with an architect can send us drawings to estimate and build; owners starting from scratch can have Harrod Drafting & Design, our sister studio, draw the house and the permit set.

How we help

What Harrod Built brings to an Almaden new home

Harrod Built (CSLB #986950) is a family-run general contractor building on the Peninsula, in the South Bay and on the Central Coast. On a new home or a whole-home rebuild in Almaden Valley, our part usually includes:

• Lot review up front. Zoning, Single-Family House Permit triggers, trees, geologic and flood mapping, WUI status and fire review, checked before an estimate.
• Estimates during design. Pricing while choices are still open, including height and floor area against the Planning thresholds.
• Demolition lined up. Utility disconnects, demolition permit, tree protection and any Special Use Permit questions for a replacement house set before the old house comes down.
• Site work from engineered plans. Soils, geology, grading, foundation, drainage and frontage built from the real set, not allowances.
• Run to City rules. SJPermits.org workflow, online inspections and a clean, quiet site for the street.
• Design support. Harrod Drafting & Design can draw the house and permit set, or we build from your architect’s plans.
• Landscape. Paso Robles Landscaping, our landscape company, handles planting, irrigation and hardscape to the approved plan, including fire-wise planting on WUI lots.

Before hiring any builder, look up the license on the state license lookup; the CSLB’s advice on hiring a contractor and our article on how to check a CSLB license explain what to check. Nearby we also build in Los Gatos, Saratoga, Palo Alto, Atherton and Woodside and Portola Valley, and farther south in Monterey, San Luis Obispo and Santa Barbara counties, through general contracting or design-build. Our process page walks from estimate to move-in, and our contract type comparison explains fixed-sum and cost-plus agreements. For the local market, see our page on custom homes in Los Gatos and nearby South Bay towns.

Pricing a new home or a full rebuild in Almaden? Send the address and any drawings you have. We check the zoning district, whether a Single-Family House Permit applies, the trees, geologic and flood mapping, WUI status and the submittal package, then return a written estimate.
