San Diego, CA Building Permits Guide

By Permit Place  |  Last updated: March 2026

Building permit review in San Diego, CA varies by project type and complexity, with the city offering multiple processing tracks to match different project needs. Simple residential projects may qualify for Rapid Review and be issued within days, while complex commercial projects typically require 4 to 8 weeks or more for initial plan review. The city publishes a weekly permit processing timeline snapshot that tracks current intake, review, and issuance times. Below is a full breakdown of permit timelines, costs, the application process, and how to apply through San Diego’s online permitting system.

San Diego’s Development Services Department processes thousands of building permits annually across one of California’s largest and most active construction markets. The city has invested heavily in streamlining its permitting process, offering programs like Rapid Review, Express Plan Check, and dedicated expedite tracks for affordable housing and life science projects. Understanding which processing track your project qualifies for is key to getting your permit issued as quickly as possible.

What Building Permits Do You Need in San Diego?

San Diego requires permits for most construction activity. The Development Services Department issues building permits across several categories, and the type of permit you need depends on your project scope, building use, and whether the work affects structural, mechanical, electrical, or plumbing systems. The city also requires separate trade permits and may require discretionary approvals depending on zoning and environmental factors.

Commercial Building Permits

• New commercial construction: Full plan review with the longest timeline, reviewed by multiple divisions simultaneously including building, fire, planning/zoning, and public works. Requires construction drawings, structural engineering, MEP plans, Title 24 energy compliance, and storm water documentation.
• Tenant improvements and interior buildouts: Plan review for structural, electrical, plumbing, and mechanical changes inside an existing commercial space. Simple interior office TI projects up to 20,000 square feet may qualify for Professional Self-Certification, which can significantly reduce review time.
• Change of use: Required when converting building use (for example, retail to restaurant, office to medical clinic, or warehouse to lab space). May trigger additional zoning review and fire department requirements.
• Shell and core: Covers the building envelope and base building systems, separate from tenant improvement permits.
• Master plan permits: Available for phased development projects, allowing the overall project to be reviewed comprehensively while individual phases are permitted separately.
• Capital Improvement Projects (CIP): Separate building permit category for publicly funded capital improvement projects.

Residential Building Permits

• New home construction (single dwelling unit): Full plan review including structural, mechanical, electrical, plumbing, Title 24 energy compliance, and solar PV requirements. New homes in San Diego must include solar photovoltaic systems under the 2022 California Energy Code.
• Additions and remodels: Required when modifying structure, adding square footage, or making changes that affect load-bearing walls, electrical panels, plumbing, or HVAC systems.
• Accessory Dwelling Units (ADUs): San Diego allows up to three ADUs on a single-family lot by right: one detached ADU, one converted from existing space, and one Junior ADU (JADU). The Affordable ADU Bonus Program allows up to five total units. New detached ADUs over 620 square feet require solar panels under Title 24.
• Multi-family residential: Full plan review for apartments, condominiums, and mixed-use residential projects. Separate permit category from single-family construction.
• Decks, pools, fences, retaining walls: Separate permits with typically faster review. In-ground pools always require permits. Retaining walls over 3 feet require a building permit.

What Does Not Require a Permit in San Diego?

Some minor work in San Diego does not require a building permit under San Diego Municipal Code Section 129.0203:

• Repairs involving replacement of components with similar materials for maintenance purposes, with aggregate valuation under $1,000, that do not affect electrical, plumbing, or mechanical installations
• Replacement doors and windows in existing openings in detached single-dwelling units, duplexes, or townhouses when no modifications to exterior flashings or rough openings are needed
• Patio covers, carports, and horse shade covers accessory to residential properties up to 300 square feet of projected roof area
• Repair, installation, or removal of household appliances in residential buildings (except connections to electrical sources unless using a permanently installed receptacle)
• Replacement water heaters with no change to unit type when installed by a licensed plumbing contractor
• Replacement toilets, bidets, showerheads, or faucets when limited to repair or replacement by the building owner or licensed plumber
• Prefabricated above-ground pools of 5,000 gallons or less
• Painting interior or exterior surfaces
• Cosmetic finish work that does not affect structure, electrical, plumbing, or mechanical systems

Note: All in-ground swimming pools require a permit. All solar PV installations require a permit. When in doubt, contact DSD at (619) 446-5000 or check the city’s “What Permits Do I Need?” online tool.

Other San Diego Permit Types

• Demolition permits: Required before any teardown or partial demolition. Structures 45 years or older require a photographic survey and county building records review before demolition.
• Sign permits: Required for new or modified signage on commercial properties.
• Grading permits: For earthwork, excavation, and site preparation. Governed by Information Bulletin 502.
• Public right-of-way permits: For work in city streets, sidewalks, and public areas.
• Solar PV permits: Required for all photovoltaic installations. The city has streamlined the solar permitting process to support California’s clean energy goals.
• ADU permits: Dedicated permitting track for accessory dwelling units with specific application requirements under Information Bulletin 400.

Trade Permits

Individual trade permits are required for electrical, plumbing, gas, and mechanical (HVAC) work. These are separate from the building permit and are governed by Information Bulletin 103 (Fee Schedule for Mechanical, Electrical, Plumbing/Gas Permits). Trade permits may be pulled by licensed trade contractors. Fire alarm and fire sprinkler work also requires separate permits and inspections.

How the San Diego Permit Review Process Works

Step 1: Determine Your Permit Requirements

Before submitting, determine which permits your project needs. San Diego’s online “What Permits Do I Need?” tool helps identify required permits based on your project type. For commercial projects, you will typically need a building permit plus separate trade permits for electrical, plumbing, mechanical, and fire protection work. You may also need discretionary approvals (site development permits, conditional use permits) depending on your project’s zoning and environmental context.

Step 2: Prepare Your Application Documents

Gather all required documents before submitting. For commercial projects, you will typically need architectural construction plans, structural engineering plans, MEP (mechanical, electrical, plumbing) drawings, a site plan, California Title 24 Energy Efficiency Standards forms, a Storm Water Requirements Applicability Checklist (DS-560), and a Project Contacts Information form (DS-345). Residential projects require construction drawings, site plans, and Title 24 compliance documentation. Structures 45 years or older require a photographic survey. Non-residential projects require a Hazardous Materials Reporting Form (DS-165).

All documents must be submitted as properly formatted PDF files. Use the city’s Scout tool to validate your PDFs and ePlanSNAPP to verify sheet numbering before submitting. Improperly formatted files are a common cause of delays during the intake phase.

Step 3: Submit Through Accela

Submit your permit application online through the Accela Citizen Access portal. You will need to create a user account if you do not already have one. Once submitted, your application enters the intake phase where DSD staff screen it for completeness. If documents are missing or improperly formatted, DSD will request corrections before the application moves to plan review. For assistance with user accounts or document uploads, call (619) 446-5000.

Step 4: Plan Review

The city reviews your submitted plans for compliance with the 2022 California Building Code, structural integrity, fire and life safety, energy code (Title 24), ADA accessibility, storm water management, and applicable zoning requirements. Commercial projects are reviewed by multiple divisions at the same time. The initial review takes 4 to 8 weeks for standard commercial projects, though timelines vary by complexity and current DSD workload. The city publishes a weekly timeline snapshot with current estimated processing times.

Step 5: Corrections and Resubmittal

If the city issues correction comments, you will need to revise your plans and resubmit through Accela. Each recheck cycle adds approximately 2 to 4 weeks. Most commercial projects go through 2 to 3 correction cycles before final approval. Submitting a complete, code-compliant application on the first attempt is the single best way to shorten your total permit timeline. Express Plan Check includes up to two rechecks in the fee for qualifying projects.

Step 6: Permit Issuance and Inspections

Once all review divisions approve your plans, the building permit is issued and fees are due. Permit issuance typically takes 1 to 2 business days after all approvals are received. Schedule inspections through the Accela portal as work progresses. San Diego requires inspections at key construction milestones including underground utilities, foundation, framing and rough-in (all trades), insulation, and final. All frame and rough inspections must be completed after all rough floor, wall, and roof framing is complete and all electrical, mechanical, plumbing, fire alarm, and fire sprinkler components are properly installed.

Expedited Review Options

San Diego offers several programs to accelerate permit processing:

• Rapid Review: For minor-scope projects determined at the time of submittal. No additional cost. Formerly called Over-the-Counter review. Many simple residential projects qualify.
• Express Plan Check: Available for most project types and disciplines. Charges an administrative fee plus 1.5 times the standard plan check fee. Includes up to two rechecks. Significantly reduces the standard review timeline.

San Diego Permits: Self-Filing vs. Using a Permit Expediter

San Diego County and City Permit Jurisdiction

San Diego is the county seat of San Diego County, the second most-populous county in California. If your project is within San Diego city limits, you apply through the City of San Diego Development Services Department. Projects in unincorporated San Diego County outside city limits follow San Diego County Planning and Development Services (PDS) rules, which have different requirements, fee schedules, and timelines. The county’s PDS office can be reached at (858) 565-5920.

San Diego County also contains 17 other incorporated cities, each with their own permitting departments. Check your project address carefully to determine whether your property falls under the City of San Diego, unincorporated county jurisdiction, or another incorporated city. Properties near city boundaries may fall under different jurisdictions than expected.

California-Specific Requirements for San Diego Projects

San Diego projects must comply with several California-specific requirements that do not apply in other states:

• Title 24 Energy Code (2022): All new construction and major renovations must comply with California’s energy efficiency standards. New single-family homes and low-rise multi-family buildings must include solar photovoltaic systems. New detached ADUs over 620 square feet also require solar panels. Energy compliance documentation must be submitted with permit applications.
• CALGreen (Title 24, Part 11): California’s green building standards code requires water efficiency measures, material conservation, indoor air quality protections, and construction waste diversion for new construction and major renovations.
• Seismic requirements: San Diego is in Seismic Design Category D. All structures must meet California’s earthquake-resistant design standards, which are more stringent than the base International Building Code. A Strong Motion Instrumentation surcharge is added to all building permits.
• Climate Action Plan: The City of San Diego’s Climate Action Plan targets net-zero emissions by 2035. This drives building electrification requirements and energy efficiency standards that may exceed state minimums. All-electric construction is encouraged and may become mandatory for certain building types.
• Historical structures (45+ years): Structures 45 years or older require a photographic survey and county building records review before permits for demolition or significant alteration are issued.
