San Bernardino County is one of the most popular areas in Southern California for home projects — garage conversions, room additions, remodels, new patios, detached units, or full new construction. With fast growth in cities like San Bernardino, Fontana, Ontario, Rancho Cucamonga, and Victorville, many homeowners want to know: how do you get building permits fast in San Bernardino County?

In 2026, San Bernardino County typically issues building permits in 50–90 days if everything is submitted correctly — one of the faster timelines in Southern California. But mistakes in plans, missing Title 24 reports, or incomplete applications can add months. Here’s a step-by-step guide to getting your building permit fast in San Bernardino County.

Step 1: Check Zoning & Eligibility (1–2 weeks)

Confirm your project is allowed.

Allowed zones: Most residential zones (R-1, R-2, R-3, etc.) permit additions, remodels, garages, patios, and ADUs.
Size limits: ADUs up to 1,200 sq ft; additions/remodels follow lot coverage and setback rules.
Setbacks: 4 ft side/rear minimum, no front setback if attached (state ADU law overrides stricter local rules).
No parking minimums: Eliminated for ADUs near transit (most areas qualify).
Height: 16–18 ft for detached structures.
HOA rules: State law prevents HOAs from banning ADUs or most additions.

Check your parcel on the San Bernardino County Zoning Map or call Planning (909-387-8311). Michael's Drafting can do a quick eligibility check for your address.

Step 2: Design & Drafting (2–6 weeks)

Accurate plans are the #1 way to speed up permitting.

Hire a drafter familiar with San Bernardino County rules (Michael's Drafting specializes in this, typically 2–3 weeks for permit sets).
Plans needed: Site plan, floor plans, elevations, sections, MEP (mechanical, electrical, plumbing), Title 24 energy report, structural calculations.
Include: Fire separation, tempered glazing, dryer vent details, future EV/ESS readiness, aging-in-place features.
Cost: $3,500–$12,000 for full permit-ready set.

Michael's Drafting reviews early drafts to avoid common county corrections (e.g., Title 24 or setback issues).

Step 3: Submit Permit Application (Day 1)

Use San Bernardino County’s Online Permitting Portal (Accela) or Planning Department.

Required forms: Building Permit Application, ADU Checklist (if applicable), Zoning Clearance.
Submit: Plans (PDF), Title 24 report, owner affidavit, fees ($5,000–$15,000 depending on project size).
Electronic submittal is fastest.

Michael's Drafting can prepare and submit your package.

Step 4: Plan Review & Corrections (30–60 days)

Reviewers check CRC, Title 24, and local codes.
Common issues: Missing Title 24 report, inadequate dryer vent routing, garage fire separation, or setbacks.
Comments usually 1–2 rounds.
Respond within 30 days — Michael's Drafting handles revisions fast.
