“Permit history is a disclosure obligation in California real estate. Unpermitted work discovered by a buyer's inspector typically results in price reductions, repair requirements, or deal cancellations. The permit cost is 1.5–3% of project cost. The value of the permit record — as insurance, as a quality control checkpoint, and as future resale protection — is easily 10x the permit fee.”
Request a payment bond on any project over $50,000. A payment bond ensures that subcontractors and material suppliers are paid even if the general contractor defaults. Without a payment bond, you can be required to pay twice for the same work if the GC fails to pay their subs. Payment bonds cost 1–2% of the contract amount — the cheapest insurance available.
Yes. Any kitchen or bathroom remodel in San Dimas that involves electrical changes (new circuits, outlet additions), plumbing changes (moving fixtures, replacing supply/drain lines), or structural changes (removing walls, adding windows) requires LADBS permits. Working without required permits creates unpermitted improvement disclosure obligations at sale and can result in stop-work orders and fines.
In San Dimas, spring (March–June) and early fall (September–October) are the optimal times to start renovations. These periods avoid the Valley's peak summer heat (which affects worker productivity and material handling) and the December–February rainy season (which can affect exterior work and grading projects). Starting in spring also allows permit applications to process before the busy summer season.
For kitchen remodels and bathroom remodels in San Dimas, most clients stay in the home with reduced access to the affected spaces. For full home renovations, ADU construction, or room additions, temporary accommodation for 2–6 months is often preferable. Dust control, noise during work hours (7am–6pm per LA noise ordinance), and disruption to HVAC systems are the primary quality-of-life considerations.
