Do I need a permit in San Bernardino, CA?
San Bernardino's permit requirements follow California's Building Standards Code (Title 24), which adopts and modifies the 2022 IBC. The City of San Bernardino Building Department administers permits across a geographically diverse jurisdiction: the city proper sits in the inland empire's hot-summer basin; the surrounding unincorporated county areas climb into mountains where frost depth and seismic risk change dramatically. What triggers a permit in one part of San Bernardino may differ from another, so local zoning and environmental factors matter as much as the state code.
The state allows owner-builders to pull permits for their own residential work under California Business and Professions Code § 7044 — but there's a critical catch: you cannot do electrical, plumbing, HVAC, or gas work yourself. Those trades must be licensed. Many San Bernardino homeowners miss this distinction and end up in disputes with the city or facing failed inspections. A 90-second call to the Building Department before you start saves weeks of rework.
San Bernardino's inland location means high summer heat, occasional seismic activity, and in the mountains, freeze-thaw cycles that affect footing depth. The city has adopted local amendments to Title 24 addressing these conditions. Deck footings in the foothills, for example, must account for the frost line if you're above 3,000 feet elevation. Pool barriers must meet California's specific safety code — not just the IRC. These local wrinkles are easy to miss if you're copying a permit template from another state or county.
Most projects — decks, sheds, roof replacements, interior remodels, solar installations, room additions — require permits. The building department offers both over-the-counter and by-appointment plan review. Turnaround times vary: simple projects (residential electrical subpermits, roof replacements) often get approved same-day; complex remodels or commercial projects can take 2–4 weeks.
What's specific to San Bernardino permits
San Bernardino adopted the 2022 California Building Standards Code with local amendments. The city does not use the 2022 IBC directly; California modifies and augments it, and San Bernardino adds further requirements. The most common surprise: California and San Bernardino's electrical code (Title 24 Part 3, based on the NEC) includes demand-response and Title 24 Title 20 efficiency rules that the base NEC doesn't. If you're hiring an electrician, they'll know this. If you're doing your own minor work (under the owner-builder exemption, which excludes electrical), the city will verify Title 24 compliance during plan review and inspection.
Seismic compliance is built into every permit. San Bernardino sits in a seismically active region (San Andreas Fault proximity, local shear zones). All new construction and most significant remodels trigger seismic review. This means foundation bolting (cripple-wall bracing) for older homes, lateral bracing for new additions, and seismic connectors for mechanical equipment. The building department's plan reviewers flag seismic deficiencies routinely; expect to revise drawings if you haven't addressed it upfront.
The frost-depth issue is location-specific and easy to mishandle. In the city proper (lower elevation), frost depth is minimal — the IRC's 12-inch minimum typically applies. But if your project is in the San Bernardino Mountains or foothills (elevation above 2,500 feet), frost depth can reach 18–30 inches, and the local amendments require footings to extend below the frost line. The city's online resources or a 10-minute call to the Building Department will clarify which frost-depth rule applies to your address. Get it wrong and you'll fail footing inspection and have to excavate deeper.
Plan review in San Bernardino is thorough and occasionally slow. The building department requires detailed site plans, foundation details, electrical one-line diagrams, and Title 24 compliance documentation before most permits are issued. Incomplete submittals get rejected with a detailed list of deficiencies; resubmission averages 1–2 weeks. The city has made progress with an online permit portal, but as of this writing, many projects still require in-person or mail submission. Check the current portal status when you file — the department updates its process regularly.
Pool and spa permits are a flashpoint. California Title 24 Part 2 (Building Standards Code) includes strict pool safety rules: barriers must be 4 feet high, gates must self-close and self-latch, drain systems must meet VGBA (Virginia Graeme Baker Act) standards, and anti-entrapment compliance is verified at rough-in and final inspection. Homeowners who build first and permit after often find themselves replacing entire barrier systems or drain covers. File the pool permit before construction starts, not after.
Most common San Bernardino permit projects
These are the projects that land on San Bernardino homeowners' desks most often. Each has its own filing path, fee structure, and inspection cadence. Click through to the detailed guide for your project type.
Residential Decks and Patios
Attached decks over 30 inches high, any deck on an elevated lot or hillside, and all decks in seismically active foothills require a full building permit. Ground-level patios (6 inches or less) are typically exempt. San Bernardino's frost-depth rule applies if you're above 2,500 feet; deck footings must be certified below the frost line. Plan for 2–3 inspections: footings, framing, final.
Roof replacement
Roof replacements and major repairs in San Bernardino require a permit and seismic review if the work involves removing and replacing more than 25% of the roof. Re-roofing with like material over 75% of the roof area can sometimes qualify for a simpler permit path. Title 24 cool-roof requirements apply to any roof replacement; white or light-colored roofing is required in many cases to meet energy efficiency standards.
Room additions
Adding a bedroom, expanding a living area, or converting a den into a bedroom requires a building permit, Title 24 energy compliance review, and often a planning review. Bedrooms must have an egress window per California Title 24 Part 2. San Bernardino's seismic overlay will require foundation assessment and lateral bracing if you're connecting to an existing structure. Expect 3–4 weeks for plan review and 4 inspections.
Solar Installations
California's streamlined solar-permit process (Assembly Bill 2188) applies in San Bernardino for residential rooftop PV systems. Single-family homes can file a simplified permit form; the city has 10 days to approve or issue corrections. Battery storage, ground-mounted arrays, and commercial systems follow the full permit path. Most residential solar permits are approved same-day or within 5 business days.
Pools and Spas
Every pool and spa requires a building permit in San Bernardino, regardless of size. Barriers, electrical service, plumbing, and structural work all trigger plan review and multiple inspections. California Title 24 safety rules are non-negotiable: 4-foot barriers, self-closing gates, VGBA-compliant drains. Plan for 3–5 weeks of plan review and at least 6 inspections (footing, framing, barrier, electrical, plumbing, final).
Interior Remodels and Kitchen/Bath Updates
Bathroom and kitchen remodels that involve moving plumbing lines, electrical circuits, or wall removal require a full building permit. Title 24 compliance is checked during plan review (ventilation, insulation, lighting efficiency). If you're removing a wall, structural bracing and seismic assessment are required. Most kitchen/bath permits require 3–4 inspections and plan review takes 2–3 weeks.
Accessory dwelling units (ADUs)
California's ADU law (AB 68 and AB 881) permits detached and attached accessory dwelling units in San Bernardino. The city has adopted an ADU ordinance; filing is streamlined but requires title documentation, utility plans, and proof of water/sewer capacity. Expect 2–4 weeks for plan review. Local zoning may impose setback or parking restrictions not present in the state statute.

California context for San Bernardino permits
San Bernardino operates under California Building Standards Code (Title 24), adopted state-wide. Title 24 Part 1 (General) and Part 2 (Building Standards, based on the 2022 IBC) set the baseline. California then modifies and augments—for example, California's earthquake safety rules exceed the IBC, and Title 24 Part 6 (Title 20) imposes statewide energy efficiency standards that are stricter than the IBC's energy provisions.
Owner-builders can file permits for residential work on property they own and will occupy, under California Business and Professions Code § 7044. However, you cannot perform electrical, plumbing, HVAC, or gas work yourself—those require licensed contractors. If you hire a contractor for any trade, they pull the subpermit, not you. San Bernardino's building department enforces this distinction strictly.
California also requires seismic compliance in all permits, Title 24 energy review for renovations, and accessibility review (Title 24 Part 2, Chapter 11) for public-facing work. San Bernardino adopts these state mandates without exception. Local amendments are relatively minor—mostly clarifications on frost depth in the foothills and seismic zone mapping. State code drives nearly every permit decision.
Common questions
Do I need a permit to replace my roof in San Bernardino?
Yes. Any roof replacement requires a building permit in San Bernardino. The city approves most residential roof permits quickly (same-day or next-day over-the-counter), but you must file first. If you're replacing more than 25% of the roof, expect a full structural review and seismic assessment. Title 24 cool-roof requirements also apply: white or light-colored roofing is required in many cases. Cost is typically $150–$400 depending on roof size and complexity. Failure to permit a roof replacement can trigger code-enforcement action and require expensive remediation.
Can I build a deck without a permit if it's low to the ground?
Not in San Bernardino. Any deck over 30 inches high, or any deck that includes stairs, requires a building permit. Even ground-level elevated decks typically need a permit if they're more than a few feet off grade. The city's frost-depth rule also applies in the foothills: footings must extend below the frost line (18–30 inches in higher elevations). A permit costs $200–$600 and includes plan review and 2–3 inspections. Unpermitted decks create problems when you sell or if the city learns of them; fixing it after the fact is expensive.
What's the difference between owner-builder and contractor permits in California?
As an owner-builder in California, you can pull a permit for work on property you own and occupy. You can do the actual construction work yourself, except for electrical, plumbing, HVAC, and gas — those trades must be licensed. If you hire a licensed contractor for any phase of the project, they pull the permit for that phase, not you. San Bernardino's building department verifies contractor licensing before issuing permits, so don't try to file as an owner-builder if you've actually hired trades for the work.
How long does plan review take in San Bernardino?
Simple projects (roof replacements, solar installations, straightforward repairs) can be approved same-day or within 3 business days. Complex projects (additions, remodels, pools, seismic upgrades) typically take 2–4 weeks. The city's online portal has reduced turnaround for eligible projects. Incomplete submittals are rejected with a detailed deficiency list; resubmission averages 1–2 weeks. Submit complete drawings, Title 24 documentation, site plans, and seismic assessment before you file to avoid delays.
Are there frost-depth requirements for decks and foundations in San Bernardino?
Yes, but they vary by location. In the city proper (low elevation), frost depth is minimal and the IRC's 12-inch minimum applies. In the San Bernardino foothills and mountains (above 2,500 feet), frost depth can reach 18–30 inches, and local amendments require footings to extend below the frost line. This is a common trap: homeowners copy deck plans from other regions and fail footing inspection because the footings are too shallow. Call the Building Department or check the city's geological survey map for your specific address.
What are the pool safety rules in San Bernardino?
California Title 24 Part 2 and San Bernardino local code require all pools to have 4-foot barriers, self-closing self-latching gates, and VGBA-compliant drain systems. Every pool requires a building permit (no exceptions for size), and the city conducts rough-in and final inspections on barriers, electrical, plumbing, and drains. Failing to permit a pool or using non-compliant components triggers expensive remediation and can create liability. Plan for 3–5 weeks of plan review, 6+ inspections, and $800–$2,500 in permit costs depending on pool size and complexity.
Can I do electrical work on my home if I'm an owner-builder in California?
No. California Business and Professions Code § 7044 explicitly excludes electrical, plumbing, HVAC, and gas work from owner-builder scope. You cannot pull a permit for these trades or perform them yourself, even on your own home. You must hire a licensed contractor, who pulls the electrical subpermit. Title 24 compliance is verified by the city during plan review and inspection. Homeowners who try to DIY electrical work and file it as owner-builder work face permit denial and code-enforcement action.
How much does a building permit cost in San Bernardino?
Permit fees are based on the project valuation. San Bernardino uses a tiered fee schedule: typical residential permits cost $150–$800. A roof replacement might run $200–$400. A deck or small addition costs $300–$600. A pool or major remodel costs $800–$2,000+. Plan review and inspections are included in the base fee; there are no surprise add-ons. Call the Building Department or check their fee schedule on the city website to estimate your specific project.
What is Title 24 and why does it matter for my permit?
Title 24 is California's Building Standards Code, adopted state-wide. Part 2 is the building code (based on the 2022 IBC, with California amendments). Part 6 (Title 20) is the energy efficiency code. When you file a permit in San Bernardino, the building department reviews your plans against Title 24 compliance. This includes earthquake safety, ventilation, insulation, lighting efficiency, cool roofs, and accessibility. Title 24 is stricter than the base IBC, so you can't use out-of-state plans as-is. Your contractor or designer should verify Title 24 compliance before submitting.
Do I need a permit for a solar installation in San Bernardino?
Yes, but California streamlines the process. Assembly Bill 2188 requires San Bernardino to approve residential rooftop solar permits within 10 business days using a simplified form. Most residential PV systems are approved same-day or next-day. Ground-mounted arrays, battery storage, and commercial systems require full permits. Cost is typically $200–$400. The city offers an online solar-permit portal for eligible systems. Battery-storage installations have additional requirements; verify with the Building Department.
Ready to file your San Bernardino permit?
Contact the City of San Bernardino Building Department before you start work. A 10-minute phone call will confirm whether your project needs a permit, what fee applies, and what documents you'll need to submit. If you're unsure about seismic requirements, frost depth, Title 24 compliance, or whether your work qualifies for owner-builder exemption, ask — the department's plan reviewers see the same issues repeatedly and can point you in the right direction. Submit complete drawings, site plans, and Title 24 documentation the first time to avoid rejection and resubmission delays. Unpermitted work creates problems at resale, complicates insurance claims, and invites code-enforcement action. Permitting takes 2–5 weeks for most residential projects and costs a few hundred dollars — a small investment to protect your home and avoid expensive fixes later.
