Thinking about turning that bonus room or den into a real office or a guest room in Marina Woods? You want it to look great, feel comfortable, and add value, but the permit process can feel like a maze. The good news is you can convert flex space the right way with a simple plan. In this guide, you’ll learn what triggers a permit in El Dorado County, the bedroom code must-haves, the approval and inspection steps, and a checklist that helps you avoid appraisal or lender headaches later. Let’s dive in.
When a permit is required
Not every project needs a permit. Many do, especially if you plan to use the space for sleeping or you are changing systems.
Projects that need a permit
- Structural changes, like removing or moving a load-bearing wall or enlarging openings.
- Adding or altering windows or doors that affect egress.
- Any new or modified electrical, plumbing, or mechanical work.
- Converting a room into a sleeping room, because egress, alarms, and electrical must meet current code.
Projects that usually do not need a permit
- Cosmetic work such as paint, carpet, baseboards, and trim.
- Replacing finishes without changing layout or systems.
Always verify your specific scope with El Dorado County Planning & Building Services. County rules and adopted code editions change.
When ADU rules may apply
If your conversion adds a separate kitchen or a dedicated exterior entrance that creates an independent unit, accessory dwelling unit rules may apply and a different permit pathway is required. A den converted to an office or guest room that remains part of the main home typically does not trigger ADU rules.
Bedroom vs office: code basics
If you want the space to count as a bedroom or safe sleeping room, a few code items are non-negotiable.
Safe egress for sleeping rooms
A sleeping room must have an approved emergency egress opening, such as a qualifying window or an exterior door. The opening must meet minimum clear opening size and height limits, and the window sill must be below a set height from the floor. If your room lacks an egress window, it may work as an office but not as a legal sleeping room.
Natural light and ventilation
Habitable rooms need natural light and ventilation. That usually means a window sized in proportion to the room, plus an openable sash or mechanical ventilation. If your planned office does not have an exterior window, you may need mechanical ventilation to comply.
Minimum room size and ceiling height
Common standards include at least 70 square feet of floor area, no dimension less than 7 feet, and a minimum ceiling height of about 7 feet for most of the room. Confirm the exact dimensions under the current California Residential Code adopted by El Dorado County.
Smoke and carbon monoxide alarms
Modern code requires smoke alarms in each sleeping room, outside sleeping areas, and on each level. Carbon monoxide alarms are required if your home has fuel-burning appliances or an attached garage. If walls or ceilings are opened, the county may require inter-connected, hard-wired alarms with battery backup.
Electrical and receptacles
Outlets must be spaced per code, with GFCI or AFCI protection in certain circuits. New lighting or new circuits require permits and inspections. Proper spacing and protection help you pass final inspection.
Heating and energy compliance
Habitable rooms must have a permanent heat source. If you close off ducts or change airflow, you may need a supplemental register or approved heat. Some alterations trigger California Title 24 energy documentation. The county will tell you which forms are required at plan check.
Marina Woods HOA and CC&Rs
Marina Woods likely has an HOA with architectural rules. HOA approval is separate from county permitting, and you may need it first.
Get approvals before you apply
- Review CC&Rs and architectural guidelines.
- Submit for HOA/Architectural Review Committee approval if you plan any exterior change, such as a new or enlarged window, a new exterior door, or visible vent terminations.
- Obtain written HOA approval to avoid enforcement actions and delays at the county.
Exterior visibility matters
Changes visible from the street or common areas often have additional standards. Confirm window style, trim, and placement requirements before you design your plan set.
Your permit pathway in El Dorado County
A straightforward plan and clean submittal reduce review time.
Pre-submittal checklist
- Confirm whether your scope needs a permit with El Dorado County Planning & Building Services.
- Decide if the room will be used for sleeping. Plan for egress and alarm locations if yes.
- Check Marina Woods HOA requirements and obtain written approval if required.
- If your project will exceed $500 in labor and materials, hire a licensed contractor. Using licensed professionals helps prevent rework and inspection setbacks.
What to include in your plans
- Completed county building permit application forms.
- Scaled floor plans showing existing and proposed layout, wall types, door and window sizes, and closet locations.
- Structural details if you are altering load-bearing walls or enlarging openings. Engineer or architect stamps may be required.
- Electrical plan with outlets, switches, lighting, smoke detectors, and any new circuits.
- HVAC notes if you are adding a register, moving ducts, or installing supplemental heat.
- Window schedule with sizes and egress details for sleeping rooms.
- Energy compliance documentation if required by Title 24.
- Wildfire or defensible space notes if the county requests them.
Fees are typically based on the stated valuation of work and may include plan review, permit issuance, and inspections. Confirm the current fee schedule with the county.
Reviews, fees, and timing
- Minor, interior, non-structural projects can be reviewed in days to a few weeks.
- Structural changes and exterior openings often take longer, typically 2 to 6 weeks or more.
- If plan check requests revisions, your timeline extends until you resubmit and receive approval.
After approval, you pay permit fees and receive your permit card and inspection instructions.
Inspections: what to expect
Your inspector will check that the work matches the approved plans and meets code.
Typical inspection sequence
- Rough framing, if you removed, moved, or opened walls.
- Rough electrical, plumbing, and mechanical, before insulation or drywall.
- Insulation inspection if walls or ceilings are opened.
- Drywall or final framing checks if needed.
- Final inspection to verify egress, alarms, electrical protection, and heating.
Use the county’s inspection scheduling system and have your permit number ready. If the inspector issues corrections, complete them and schedule a reinspection.
Final sign-off and records
Once you pass final inspection, the county issues a final approval. Keep that finaled permit, inspection card, plans, receipts, and HOA approvals together. You will need these for appraisers, lenders, title companies, and future buyers.
Appraisals, lending, and resale value
Permits protect your investment. Appraisers generally count only legal, permitted living area in the home’s gross living area. Unpermitted spaces can lead to rooms not counted as bedrooms, lender conditions, or closing delays.
To make your conversion work for you at sale:
- Include permit numbers and final status in your listing paperwork and agent remarks.
- Keep before-and-after photos with dates.
- Make sure a “bedroom” meets egress and alarm rules, so an appraiser can treat it as a sleeping room.
Timeline and cost overview
- Planning and HOA approvals: a few days to a few weeks.
- County plan review: a few days to several weeks, depending on scope and workload.
- Construction and inspections: several days to a few weeks, depending on complexity.
- Total timeline for a simple interior conversion without structural changes: often 2 to 8 weeks from start to final.
Permit and plan-check fees are based on your project’s valuation and the county’s fee schedule. Contractor pricing varies with scope and finishes. In California, projects over $500 require a licensed contractor.
Common pitfalls to avoid
- Assuming interior changes never need a permit. Verify with the county first.
- Calling a room a bedroom without egress. Plan for a compliant egress window or exterior door.
- Missing smoke and carbon monoxide alarms or failing to interconnect them when required.
- Skipping HOA approval for an exterior change.
- Hiring an unlicensed contractor for work over the state threshold.
- Forgetting Title 24 documentation when window or envelope changes trigger it.
- Not finaling the permit. Always pass final inspection and keep the records.

FAQs
Do I need a permit to add a closet to my den in Marina Woods?
- Adding a closet alone may not need a permit if it is non-structural and does not involve electrical, mechanical, or plumbing, but converting the space to a sleeping room triggers egress and alarm requirements. Verify your scope with El Dorado County Planning & Building Services.
Can a room without an egress window be called a bedroom for appraisal?
- No. A sleeping room needs a compliant egress opening. Without it, appraisers typically do not treat the space as a legal bedroom, which can affect value and financing.
What inspections will the county require for an interior conversion?
- Typical inspections include rough framing, rough electrical/plumbing/mechanical, insulation, and final. Inspectors often verify egress, smoke/CO alarms, electrical protection, and heating at final.
How long does county plan review usually take in El Dorado County?
- Minor, non-structural interior plans can move in days to a few weeks. Structural changes or exterior openings often take 2 to 6 weeks or more, plus time for any resubmittals.
What are the minimum size and height requirements for a bedroom?
- Common standards include at least 70 square feet, no dimension less than 7 feet, and roughly 7-foot ceiling height over most of the room. Confirm exact requirements under the current California Residential Code adopted by the county.
Do I need a licensed contractor for this kind of project?
- In California, any project with labor and materials over $500 requires a licensed contractor. Hiring licensed pros helps you pass inspections and keep permits on track.
Does converting a den into a guest room make it an ADU?
- No, not if it remains part of the main dwelling. If you add a separate kitchen or an exterior entrance that creates a standalone unit, ADU rules and a different permit pathway may apply.
