§ 02   Process

The permit, in five steps.

Local procedure varies, but the underlying sequence is consistent across nearly every U.S. jurisdiction.

  1. 01
    Determine if a permit is required
    Most jurisdictions exempt minor work — finishes, like-for-like replacement, sheds under a threshold. The wiki entry on permit-exempt work covers what's typical.
    ~5 min
  2. 02
    Prepare drawings & documents
    Plans, site plan, structural calculations if required, energy compliance forms (Title 24 in CA, REScheck elsewhere), product cut-sheets.
    1–14 days
  3. 03
    Submit & pay plan-check
    Most authorities now accept e-plan submissions. Plan-check fee is typically 65% of the permit fee, due at intake.
    same day
  4. 04
    Address corrections, pay permit, pull
    Plan-checker returns redlines; you revise and resubmit. Once approved, pay the balance and pull the permit card.
    2–8 weeks
  5. 05
    Build, inspect, finalize
    Schedule inspections at each phase (foundation, framing, rough trades, insulation, final). Pass final to close the permit and clear the property record.

§ 03   Common questions

Cross-jurisdiction basics.

For city-specific fees, timelines, or contacts, see the individual jurisdiction page.

01Do I need a permit for X?
Most jurisdictions follow the IRC R105.2 list of permit-exempt work — small accessory structures, prefabricated swimming pools, fences under 7′, like-for-like finishes. A handful of cities (San Francisco, Boston) have stricter local thresholds. Always confirm against the city page.
02Can I pull my own permit as a homeowner?
In most states, yes — for work on your own primary residence, a homeowner can act as the contractor (the "owner-builder" route). You assume liability. Most cities require an affidavit at intake. The route is generally not available for rental properties or speculative construction.
03What does a permit actually cost?
Most authorities calculate permit fees as a percentage of valuation (the cost of the work), typically 1–3%, with minimum fees of $120–$300 and additional charges for plan-check, sub-trade permits, and special inspections. Each city page lists its current fee schedule.
04What happens if I built without a permit?
Most jurisdictions allow retroactive permits. Expect 2–10× the normal fee and inspections that may require opening up walls. Unpermitted work surfaces during property sales (title-company disclosure) and can affect insurance claims.
05Why is my city not in Jaspector?
If your city is unincorporated, the county handles permits — try the parent county. If it's incorporated and missing, email hi@jaspector.com — we typically add a missing jurisdiction within 5 business days.
