Basement and in-law apartments are common and affordable around DC and Montgomery County. The good ones are great; the questions below separate them from the ones you'll regret.
Light, air, and moisture
- How many windows, and is there an egress window for safety?
- Has the unit ever flooded or had moisture or mold? What was done about it?
- How's the ventilation and humidity in summer?
Utilities and cost
- Are utilities included, or split with the upstairs household — and how?
- What's the real monthly total including internet?
Access and privacy
- Is there a private entrance, and can you come and go freely at any hour?
- Is laundry, kitchen, or storage shared or private?
- Who else has a key or access to the space?
Rules and legality
- Is the unit a legal rental? (Ask directly — it affects your rights.)
- What are the house rules on guests, noise, and parking?
Practical
- What's the lease length and is a 3–9 month term possible?
- When is it available, and what deposit is required?
Always tour in person or by live video before paying anything, and pair this with the basement inspection checklist.
