FAQ: Home Remodeling & Construction in San Jose

Do I need a permit to remodel my kitchen or bathroom in San Jose?

A permit is required when the work involves electrical, plumbing, mechanical, or structural changes. Cosmetic-only updates—painting, swapping cabinet doors, replacing countertops without moving utilities—do not need a permit. The City of San José confirmed this rule in a January 2026 blog post: “Cosmetic-only work (like cabinets or countertops with no utility changes) typically does not require a permit. If your remodel involves electrical, plumbing, mechanical or structural changes, a building permit is required”. Starting January 1, 2026, San Jose also mandates a seismic assessment for bathroom projects that add significant weight (e.g., natural stone tile). D&D Home Remodeling handles permit paperwork for every project, so the process stays compliant without extra homeowner legwork.

Major layout changes or structural work push the price to 80,000150,000. Cabinets alone consume 25–35% of the budget, and labor runs 8,00040,000+ depending on scope.

What are the rules for building an ADU in San Jose in 2026?

San Jose follows California state ADU law with local overlay requirements. Key rules effective in 2026: owner-occupancy requirements are permanently eliminated under AB 976, meaning you can rent both the main house and the ADU. Most new detached ADUs must include solar panels and meet strict Title 24 energy standards. Permit fees for a standard detached ADU under 1,000 square feet run 4,0009,500, which is lower than fees for a comparable room addition. The city offers an ADU Ally contact at adu.ally@sanjoseca.gov or 408-793-5302 for navigation help. D&D Home Remodeling has completed ADU projects of 650 sq. ft. and larger, managing design, permits, and construction.

How long does it take to get a building permit in San Jose?

Timelines vary widely by project type. Simple electrical or water-heater permits can be obtained in 1–2 weeks through the online portal (SJPermits.org). Major remodels involving plan review typically take 8–12 weeks. An Express Plan Check program offers plan review comments in 2–3 days for an additional fee (plan review is 325/hour, permit issuance is 227/hour). Permit approval for bathroom projects requiring seismic review currently averages 6–7 weeks. D&D Home Remodeling submits plans in the format San Jose reviewers expect, which helps avoid re-submission delays.

Does a home remodel in San Jose need to comply with Title 24 energy codes?

Yes. The 2025 California Energy Code (Title 24, Part 6) took effect January 1, 2026, and applies to all new construction, additions, and alterations that require a permit. The updated code mandates higher energy efficiency for lighting, HVAC, insulation, windows, and roofing. For example, cool-roof requirements now apply to re-roofing projects on single-family homes in certain climate zones. D&D Home Remodeling incorporates Title 24 compliance into every permitted project, including energy calculations and product specifications that meet the 2025 standards.

What is the true cost of a seismic retrofit for a San Jose home?

A basic bolt-down retrofit for a standard raised foundation in San Jose costs 3,0007,000. A full cripple-wall retrofit with plywood sheathing and hold-downs runs 5,0008,000. Soft-story retrofits (garage or first floor) cost 8,00015,000, and hillside or steep-slope foundations can exceed 20,000 [reference:17] .Permits 500–$1,500. The single largest cost variable is access; tight crawl spaces or finished basements can add 30–50%. Homes built before 1980 in San Jose were typically not designed for lateral movement and sit on soil types that amplify shaking, making retrofit a high-priority upgrade.

What should I check before hiring a general contractor in San Jose?

Three things: license, complaint history, and local permit experience. Verify the contractor’s license at the CSLB website (https://www.cslb.ca.gov) and confirm the license is active with no disciplinary actions. Get at least three detailed bids and compare scope, not just price. Confirm the contractor regularly pulls permits with the City of San José and can provide references from recent projects in Santa Clara County. D&D Home Remodeling is license #1128719, has a 5.0 rating on Houzz across 12 reviews, and manages permits in-house for every project.
