Construction Window
Permit review takes weeks. California's dry season doesn't wait.
Every week your permit sits in review is a week of prime building weather gone. A complete first submission is the cheapest schedule insurance you can buy.
- 01Winter rains slow excavation, concrete pours, and framing—or stop them outright.
- 02Contractors and city inspectors book out further as the dry season closes.
- 03Each correction cycle costs weeks. Getting the package right the first time protects your window.

Permit Basics
In California, Almost Every Home Project Needs a Building Permit
It's not just ADUs and additions. Cities require permits for far smaller changes than most homeowners expect—and unpermitted work surfaces later as fines, escrow surprises, or forced rework.
Windows & exterior doors
Most cities require a permit even for same-size replacement windows and doors.
Water heaters & furnaces
Water heater, furnace, and A/C replacements need plumbing or mechanical permits.
Kitchen & bathroom remodels
Moving plumbing, electrical, or walls triggers building, electrical, and plumbing permits.
Electrical panel upgrades
Panel upgrades and new circuits require an electrical permit and inspection.
Re-roofing
Tear-off and re-roof projects need a permit in most California jurisdictions.
Decks & patio covers
Decks, patio covers, and pergolas beyond minimal size or height need structural review.
Exact requirements vary by city and project scope—some minor repairs are exempt. When in doubt, we verify the local rules for you as part of a free consultation.
Already finished work without a permit?
Cities discover unpermitted work through complaints, aerial imagery, and home sales. Acting before a Notice of Violation arrives is dramatically cheaper—and a path to legalization usually exists.

Why You Need This
Why Professional Permit Handling Saves Time and Money
Cities have complex and inconsistent permit processes—our dedicated team ensures your plans move quickly through review.
Why DIY Permit Filing Often Fails
Homeowners struggle to find the correct department

Unable to interpret city comments
Correction notices require professional architectural and structural revisions.

Unpermitted Work Legalization
Need to Bring Existing Work Into Compliance?
If a remodel, addition, garage conversion, or ADU was completed before permits were issued—or City records do not match the property—you may still have a path to legalization. We help document existing conditions, identify required corrections, prepare permit plans, and coordinate with the City through final inspection.
This may apply if:
- 01Work was completed before permits were issued or finalized.
- 02You bought the property and later discovered missing permit records.
- 03You received a Notice of Violation, Stop Work Order, or correction deadline.

Published Los Angeles Example
A missed City deadline can multiply enforcement costs.
LADBS states that an Order to Comply Code Violation Inspection Fee is $356.16 when paid within 30 days. If it becomes late, an $890.40 penalty is added. This is one published Los Angeles enforcement example—not a statewide fee rule.
LADBS Code Enforcement Bureau Fees ExplainedActual deadlines, fees, penalties, and legalization options depend on the notice, jurisdiction, zoning, safety conditions, and project scope. We review the document you received before recommending a response path.

Everything you need to know about getting your plans approved faster.

We first verify the jurisdiction, permit type, review path, and required documents. We then coordinate submissions and correction responses to reduce avoidable delays. The reviewing agency controls timing and approval.
Yes. Every project receives a dedicated permit coordinator who manages communication, tracking, scheduling, and all interactions with the city.
Most projects require architectural plans, structural calculations (if applicable), site plans, and supporting engineering documents. We assemble and prepare the full submission package.
Timing depends on the jurisdiction, permit type, project scope, application completeness, required departments, correction cycles, and current agency workload. We confirm the published review path and available City targets before giving a project-specific planning range.
We interpret plan checker comments, revise your documents, and resubmit quickly. Our team resolves corrections efficiently to keep your project moving.
We work with jurisdictions across Northern and Southern California, including Los Angeles, San Jose, Fremont, Sacramento, Oakland, San Diego, and many more.
A permit expediter verifies the jurisdiction and review path, organizes required forms and supporting documents, coordinates the submittal, tracks agency comments, and keeps correction responses moving. The City still makes every review and approval decision.
Cost depends on the jurisdiction, project scope, current plan status, required departments, and whether corrections are already open. We review those inputs before defining the service scope; City permit, plan-check, consultant, and inspection fees are separate.
