I’M PLANNING A PROJECT

Where should I begin?

Build the scope, budget, sequence, and questions for the project team.

I OWN AN OLDER HOME

What needs approval?

Check records, historic review, permits, and shared-building requirements.

ANSWERS FIRST

Start with the question in front of you.

Open a question for the short answer, then follow the guide for scope details, sources, and the next decisions.

Plan the project

Where should I start before collecting renovation bids?

Define what must change, what can stay, and the finished result. Review records and investigate assumptions that could materially change the scope before comparing prices.

Budgets and sequencing ↗
What should the budget include beyond construction?

Account for investigation, design, approvals, owner purchases, temporary arrangements, finish restoration, inspections, and a reserve for identified uncertainty. Avoid treating exclusions as contingencies.

Budgets and sequencing ↗
How long will the renovation take?

Ask for a property-specific schedule separating design, review, procurement, construction, inspections, and corrections. Identify the dependencies behind the completion date.

Budgets and sequencing ↗
Should I renovate before selling?

Compare repairs, modest preparation, and a larger remodel using likely net proceeds, carrying costs, time, and execution risk. Do not assume every dollar of renovation cost returns at sale.

Budgets and sequencing ↗

Check records and approvals

Does my renovation need permits?

Have DBI and the project professionals classify the actual work. Building, electrical, plumbing, mechanical, structural, and use changes can raise different requirements.

Permits and historic homes ↗
What changes for a Victorian or historic home?

Check resource status and discuss the proposed work with Planning. Exterior details, windows, additions, and designated interiors may need review before products are ordered.

Permits and historic homes ↗
Can I renovate inside a TIC or condo without asking other owners?

Check the governing documents for common elements, approvals, insurance, access, shutdowns, and work hours. Private approval and city permits are separate requirements.

Permits and historic homes ↗
What if earlier work has incomplete permit records?

Investigate the actual layout, authorized use, application and inspection history, and any violations. An application or issued permit does not by itself establish completed sign-off.

Permits and historic homes ↗

Investigate the systems

Does visible knob-and-tube mean the wiring is active?

Not necessarily. Old supports can remain after replacement, while hidden sections may still be energized. Have a licensed electrician establish the extent and condition.

Knob-and-tube wiring ↗
Does a newer electrical panel mean the home was rewired?

No. Panel, service, and branch-circuit work are different scopes. Ask what remains active and how the proposed changes fit the current and planned loads.

Knob-and-tube wiring ↗
How should I compare rewire costs?

Use the same circuit and room scope and account for permits, access, service changes, material assessment, plaster repair, painting, inspections, and documentation.

Knob-and-tube wiring ↗
Should I repair a stain before investigating the leak?

Establish the source and affected materials first. Roof, exterior, supply plumbing, drains, and condensation can require different investigations and repairs.

Roofs, plumbing and moisture ↗

Plan a kitchen or bathroom

Why does moving fixtures change the remodel scope?

Relocation can affect plumbing, electrical demand, ventilation, shared systems, structure, and neighboring spaces. Resolve those dependencies before treating the design as a fixed-price job.

Kitchens and bathrooms ↗
What should the contractor specify behind the tile?

Request the proposed waterproofing assembly, compatible products, installation responsibility, and required testing or inspections. The finished tile alone does not document concealed work.

Kitchens and bathrooms ↗
Is buying a new exhaust fan enough?

Confirm capacity, routing, discharge, and shared-system conditions with the appropriate professional. A new fan may not resolve an unsuitable duct or a separate moisture source.

Kitchens and bathrooms ↗
When should I order cabinets, fixtures, and appliances?

After dimensions, compatibility, approvals, and the procurement schedule are coordinated. Assign responsibility for delivery, damage, storage, missing parts, and installation accessories.

Kitchens and bathrooms ↗

Review structural questions

Does a crack or sloping floor prove a foundation problem?

It is an observation that needs investigation, not a diagnosis. Have the appropriate professional assess the cause, scope, and limitations of the available information.

Foundations and seismic work ↗
Can I remove a wall or enlarge an opening?

Have the design and engineering team assess the building’s load path and the proposed change before pricing demolition. Confirm permits and any shared-building approvals.

Foundations and seismic work ↗
Does soft-story program status establish earthquake safety?

No. Review the actual program record, permits, scope, and completion evidence. Mandatory-program coverage and a building’s broader vulnerabilities are different questions.

Foundations and seismic work ↗
Does a retrofit make a home earthquake-proof?

No retrofit should be treated as a promise of no damage. Ask a qualified engineer what the completed scope addresses and what vulnerabilities or limitations remain.

Foundations and seismic work ↗

Understand older materials

Should I repair plaster or replace it with drywall?

Compare condition, required access, original details, repair skill, and applicable building requirements. Price the finished result rather than assuming either approach is always cheaper.

Plaster, lead and asbestos ↗
Do I need to consider lead paint before opening walls?

Work in pre-1978 housing can disturb lead-containing paint and create dust. Confirm the assessment and applicable lead-safe requirements with appropriately qualified professionals before disturbance.

Plaster, lead and asbestos ↗
Can I tell whether old flooring or insulation contains asbestos?

Appearance is not a reliable test. Arrange a qualified professional assessment when suspected material is damaged or work would disturb it; do not take samples yourself.

Plaster, lead and asbestos ↗
Can I stay in the home during the work?

Resolve safe access, usable services, work-area separation, household needs, and specialist restrictions before starting. Occupancy depends on the actual scope and professional plan.

Budgets and sequencing ↗

Hire and finish well

How do I compare contractors beyond the price?

Check licensing, relevant experience, references, supervision, insurance, exclusions, allowances, permit responsibilities, and closeout. Give every bidder the same scope.

Contractors and bids ↗
How much should a contractor ask for upfront?

CSLB states a general home-improvement down-payment limit of the lesser of $1,000 or 10%, with a narrow bonded-licensee exception. Verify the applicable rule and any claimed exception.

Contractors and bids ↗
How should changes be approved?

Use the required written, signed change order identifying the changed work, price, schedule effect, and approval implications. Track the current approved total.

Contractors and bids ↗
What should I collect before the project is closed out?

Reconcile the scope, corrections, permits, inspections, applicable payment documentation, warranties, reports, and maintenance information. Keep evidence of what was actually completed.

Permits and historic homes ↗
THE RENOVATION LIBRARY

Plan the work behind the finish.

Each guide answers a different project question. Read the whole path or go straight to the system or decision that needs attention.

BEFORE WORK STARTS

Put the scope and the unknowns in writing.

Keep the records, assessments, approvals, bids, contract, and open questions together. Make the handoffs between professionals explicit.

Open the printable project checklist ↗
  1. Establish the building’s condition and authorized use.
  2. Agree on the scope, exclusions, and full project budget.
  3. Confirm the approvals, contract, and inspection sequence.
  4. Document changes and collect the completion evidence.

Use the guides to ask better project questions.

The center connects official city, state, and federal resources with practical project-planning questions. It does not diagnose a building or replace design, engineering, electrical, environmental, insurance, or legal review. Cost examples are labeled illustrations; contractor quotes and agency requirements must fit the actual property.
